Description

  The present invention relates to a configuration description information providing apparatus that communicates with a wireless communication apparatus that can support a plurality of wireless communication systems.

  Currently, with the explosive spread of wireless communication systems, a plurality of wireless communication systems with different standards are mixed. In general, a wireless communication device is prepared for each wireless communication system. Recent mobile radio communication devices are required to be compatible with various application services such as e-mail, data communication, and Web (world wide web) browsing as well as conventional voice calls. Therefore, there is an increasing demand for a so-called multimode terminal apparatus that can handle a plurality of wireless communication systems and various application services.

  As a technique for realizing a multi-mode terminal device, a software defined radio has been proposed. In a software defined radio, a programmable device such as a DSP (digital signal processor) is used to realize at least a part of signal processing necessary for transmission / reception by software processing. A software defined radio can support various wireless communication systems and various application services by replacing software. For example, it is possible to shift from voice call to data communication, or handoff the wireless communication system from the W-CDMA system to the cdma2000 system. The basic idea of such a software defined radio is known, for example, from Japanese Patent Application Laid-Open No. 9-331579 and others, but disclosure about how to implement the device in consideration of various situations is insufficient.

  For example, in a wireless communication system, the rate of digital information to be transmitted is increased, and a standard change accompanying it is frequently made. Every time this standard is changed, it is necessary to design and develop software defined radios. The portion of the software defined radio that handles baseband signals, the so-called modem unit, has a large amount of processing and requires strict specifications such as processing delay. For this reason, the design of the modem unit is changed whenever the standard of the wireless communication system is changed. The aforementioned programmable device can flexibly cope with such a design change by changing the software. However, the capability of a programmable device such as a DSP may be insufficient for high-speed processing of broadband wireless communication signals.

  In order for a software defined radio to support various wireless communication systems and application services by switching software, it occupies many resources of the terminal device. In order to support a new wireless communication system or add an application service function, it is necessary to prepare necessary free resources. There is also a need for resource management for optimally allocating one resource for a wireless communication system or communication service. In particular, in mobile radio communication devices for mobile communication, resource management is important because the amount of resources is limited because miniaturization and low power consumption are required. A resource refers to a processor such as a CPU or DSP, hardware such as a memory, a processing capability of the processor, and the like.

  In a general design concept of a mobile radio communication apparatus, resources are fixedly allocated to a plurality of signal processes. When this concept is applied to a software defined radio, the radio must be compatible with a plurality of radio communication systems and a plurality of application services, so that resource utilization efficiency is significantly reduced. Resource management found in computers is mainly specialized in the memory area, and no consideration is given to resource management based on hardware space and resource management according to radio quality.

  In the software defined radio, for example, as described in JP-A-9-331579, a software module is downloaded through a communication line and stored in a storage device. When the software radio is repeatedly downloaded in order for the software defined radio to support a new communication service, the amount of modules stored in the storage device increases. Since the capacity of the storage device in the wireless device is finite, in reality, it is necessary to delete unnecessary modules from among the modules already stored before downloading. In response to the module upgrade, it is also necessary to consider updating the module stored in the storage device. In order to delete or update a module, it is inefficient to determine the module to be deleted or updated by referring to the name or version of the module in the storage device. Realization of a mechanism for efficiently managing modules is desired.

  In the various applications described above that can be handled by the software defined radio, a list of Web pages browsed by the user of the radio and a list of telephone numbers and e-mail addresses of specific communication partners of the user are displayed as menus. It is generally done. However, in general, a software defined radio capable of supporting a plurality of wireless communication systems cannot use the files of these lists if the wireless communication system to be adapted is changed. Each wireless communication system provides a unique application service defined by a communication service company that operates the system, and a browser and mail system according to a unique specification.

  Since application service specifications differ for each wireless communication system, a list file of Web pages, telephone numbers, and mail addresses must be prepared for each wireless communication system. This is because the file format used in the application service specific to each wireless communication system is a format specific to the application service. Therefore, in a software defined radio, a Web page, a telephone number, and an e-mail address list file described in a file format compatible with a certain wireless communication system cannot be diverted to other wireless communication systems. When the user of the software defined radio changes the wireless communication system to be used, a list file for the application service of the wireless communication system must be newly created. Furthermore, there is an inconvenience that the user must manage the list file for each of a plurality of wireless communication systems that may be used.

  An object of the present invention is to enable accurate and efficient resource management of a signal processing device in a wireless communication apparatus.

  In order to solve the above problems, according to the present invention, there is provided a configuration description information providing apparatus for communicating with a wireless communication apparatus including a signal processing device having a resource for performing signal processing related to at least a modem function and a protocol function, A storage device for storing the configuration description information describing a configuration of a signal processing function related to a modem function and a protocol function corresponding to each wireless communication system, and resource usage status of the signal processing device transmitted from the wireless communication apparatus. And receiving the configuration description information describing the configuration of signal processing functions related to other modem functions and protocol functions corresponding to each of the plurality of wireless communication systems and resource allocation information to the wireless communication device A configuration description information providing apparatus comprising a wireless transmission / reception device is provided. It is.

  ADVANTAGE OF THE INVENTION According to this invention, the resource management of the signal processing device in a radio | wireless communication apparatus can be performed accurately and efficiently.

(First embodiment)
Referring to FIG. 1A, the mobile radio communication apparatus according to the present embodiment receives an RF (high frequency) signal from a base station (not shown) via an antenna 1 and transmits an RF signal to the base station. Do. A reception signal from the antenna 1 is converted into a digital reception IF (intermediate frequency) signal by the wireless transmission / reception device 2 and supplied to the signal processing device 3. The digital transmission IF signal generated by the signal processing device 3 is converted into a transmission RF signal by the wireless transmission / reception device 2 and supplied to the antenna 1.

The signal processing device 3 includes hardware resources such as an LSI processor, a memory, and a logic circuit, and mainly performs processing of the modem unit 3A and the protocol 3B necessary for transmission / reception as shown in FIG. Specification of the modem units 3A and protocol. 3B, for example with respect to the W-CDMA (Wide band code- division multiple access) system, as defined in TS 25 series of ^{3 rd Generation Partnership Project (3GGP TM} ), GSM (Global system for mobile communications) is defined in 3GGP ^TM TS 05 series.

  The processing of the modem unit 3A (also referred to as a baseband unit) is signal processing in a region (baseband region) close to the wireless transmission / reception device 2. More specifically, the process of the modem unit 3A is a process of demodulating a sampled digitized IF (intermediate frequency) signal output from the wireless transmission / reception device 2 to generate a reception baseband signal, transmission data Is a process for generating a transmission burst band signal. The processing of the protocol unit 3B (also referred to as L2 / L3 protocol unit) is protocol processing determined according to the wireless communication system in which the mobile wireless communication device is used.

  The resources of the signal processing device 3 are controlled by the resource controller 4. With this control, it is possible to immediately respond to changes in the functions and specifications of the mobile radio communication apparatus accompanying changes in usage conditions, thereby making it possible to easily implement handover control associated with movement between different radio communication systems. Specifically, the function of the mobile radio communication apparatus is desired by the resource controller 4 performing software change control, logic circuit configuration method change control, or both controls on the resources of the signal processing device 3. Changed to In this way, the resources of the signal processing device 3 are adaptively controlled by the resource controller 4 so that the limited amount of resources can be used effectively.

  Of the resources of the signal processing device 3, an area for performing processing sufficient for software processing is realized by a general-purpose processor and a memory, and an area for which processing speed is required is a DSP (digital signal processor) or PLD (programmable). It is realized by a hardware circuit such as a logic device. The DSP performs desired signal processing according to the program read from the storage device 5 under the control of the resource controller 4. The PLD performs a desired process by describing a circuit configuration according to a program read from the storage device 5 under the control of the resource controller 4.

  The storage device 5 holds software (a program and a module that is a component of the program) used in the signal processing device 3, processing data such as reception data and transmission data, and a database such as a telephone book and an address book. ing. The storage device 5 reads / writes necessary programs and data under the control of the resource controller 4 or the system controller 6 that controls the entire interior of the mobile radio communication device. A program read from the storage device 5 is described in the signal processing device 3. As the storage device 5, a small hard disk drive device or a semiconductor memory such as FROM is used.

  The input / output device unit 7 connected to the system controller 6 includes various input / output devices that serve as an interface with the user of the mobile radio communication apparatus, such as a microphone for voice input, a speaker for voice output, a keyboard, and a display. Is included. The keyboard is used for dial keys, function key operations, text input, editing operations, and the like. On the display, incoming call information, contents, menus, and the like are displayed. The input / output device unit 7 further has an MPEG interface for performing moving image compression / decompression processing and a USB interface for performing serial input / output with an external device. These components of the input / output device unit 7 are connected by an internal bus, and the internal bus is connected to the system controller 6.

  FIG. 2 shows an example of a specific configuration of the wireless transmission / reception device 2 in FIG. The reception system will be described. An RF reception signal from the antenna 1 is guided to a low noise amplifier 11 by a transmission / reception changeover switch (or duplexer) 10. An RF signal amplified to a required level by the LNA 11 is input to a mixer 13 via a BPF (band pass filter) 12, where it is mixed with the first local signal LO 11 for reception from the frequency synthesizer 20, thereby down-converting. Is done. The output signal from the mixer 13 is input to the mixer 16 via the IF amplifier 14 and the band-pass filter 15, where it is mixed with the second local signal LO12 for reception from the synthesizer 20, thereby down to the required intermediate frequency. Converted. An output signal from the mixer 16 is input to the A / D converter 18 through the low-pass filter 17 and converted into a digital IF signal 19. The IF signal 19 is input to the signal processing device 3.

  In the transmission system, the digital IF signal output from the signal processing device 3 is converted into an analog signal by the D / A converter 22 and then input to the mixer 24 through the low-pass filter 23, where it is transmitted from the synthesizer 20. Up-converted by being mixed with the trusted first local signal LO21.

The output signal from the mixer 24 is input to the mixer 27 via the band-pass filter 25 and the IF amplifier 26, where it is mixed with the second local signal LO22 for transmission from the synthesizer 20 to increase the required RF frequency. Converted. An RF output signal from the mixer 27 is amplified by a power amplifier 29 through a bandpass filter 28, guided to the antenna 1 by the switch 10, and radiated from the antenna 1 as a radio wave.

  The signal processing device 3 in FIG. 1A includes a general-purpose processor (CPU) 31, a signal processing unit 32 (SPU), a memory 33, and an input / output interface 34, for example, as shown in FIG. Yes. The CPU 31 executes processing according to a program given in advance, and transmits predetermined commands and data to the SPU 32 to cause the SPU 32 to perform advanced signal processing. Conversely, the CPU 31 can change the processing content in accordance with a command or trigger from the SPU 32.

  By installing a program in the CPU 31 and the SPU 32 by the resource controller 4, the signal processing functions of the CPU 31 and the SPU 32 are defined. Further, the resource controller 4 determines the sharing of processing to be performed by the CPU 31 and the SPU 32. In FIG. 3, the resource controller 4 is described as being realized by a program operating on the CPU 31, but can also be realized by a sequencer on a DSP or a logic circuit.

  The SPU 32 is a programmable dedicated processor specialized for signal processing, and specifically, at least one of a DSP and a PLD is used. The SPU 32 performs signal processing using the memory 33 as a work memory. The SPU 32 inputs a signal to be processed and outputs a processed signal between the wireless transmission / reception device 2 and the system controller 6 via the external interface 34. Examples of specific processing performed by the SPU 32 include “correlation calculation”, “complex operation”, “maximum value detection”, “memory address conversion”, “sequencer”, “high-speed input / output processing”, “cumulative addition” ", And" function operation ".

  A case where the radio signal processing device according to the present embodiment is applied to a CDMA (code-division multiple access) system will be specifically described. For example, the SPU 32 in the signal processing device 3 or both the SPU 32 and the CPU 31 is provided with a resource (a despreading circuit resource) including, for example, a plurality of logic circuits that performs the despreading process in the CDMA system. The resource is controlled by the resource controller 4. The CDMA system requires a function of a RAKE receiver that operates at finger timing corresponding to multipath transmission and a function of periodically searching for finger timing. The finger timing search is performed in consideration of a mobile communication environment in which multipath timing varies. Both of these functions are realized by a despreading circuit including a correlation circuit. Conventionally, separate despreading circuits are fixedly assigned to both functions.

  According to the present embodiment, the resource management by the resource controller 4 makes it easy to use the despread circuit resources used for RAKE reception in the search process at regular intervals or at any time according to communication quality or the like. It is. This ensures high-quality communication with a smaller circuit scale. In a CDMA receiver that receives a plurality of code channels, a despreading circuit resource is allocated to each channel by resource management by the resource controller 4 according to connection / disconnection of the code channel. In this way, RAKE reception of a plurality of channels can be realized with finite despreading circuit resources, and the circuit scale can be reduced.

  As illustrated in FIG. 3B, the SPU 32 includes, for example, a plurality of DSPs 37 </ b> A and 37 </ b> B and a PLD 38, and these are connected by an internal bus 39. The processing of the despreading circuit resource can be performed by both the DSPs 37A and 37B and the PLD 38. In the case of this configuration, the processing capabilities or MIPS values of the DSPs 37 </ b> A and 37 </ b> B and the PLD 38 correspond to a part of the resources of the signal processing device 3. In the example of the CDMA system, if a processing capacity of one despreading circuit is 10 [MIPS], a DSP having a processing capacity of 100 [MIPS] is treated as a despreading resource similar to 10 despreading circuits. be able to.

  The resource controller 4 uses the resources of the DSPs 37A and 37B at that time in order to realize the functions of the mobile radio communication apparatus (RAKE reception, multipath search, neighboring cell search, multichannel reception, etc.) applied to the CDMA system. The total resources of the signal processing device 3 are allocated so as to be applied to all functions required in step (1). For example, when resources corresponding to a total of 15 despreading circuits are requested, the PLD 38 has a processing capacity of 100 [MIPS] equivalent to the capacity of 10 despreading circuits, and the remaining 5 despreading circuits The DSP 37A or 37B is provided with a processing capacity of 50 [MIPS] equivalent to the circuit capacity. The resource allocation of the signal processing device 3 is not limited to use in the same wireless communication system. For example, a CDMA system and a time-division multiple access (TDMA) system, a TDMA system and a frequency-division multiple access (FDMA) system, and an FDMA system and a CDMA system have common processing elements. For processing that is common between these different wireless communication systems and that does not compete with time, resource allocation of the signal processing device 3 can be performed in the same manner as described above.

  As described above, since the mobile radio communication apparatus according to the present embodiment can be reconstructed with a high degree of freedom, the cost and development period required for adding a function are reduced. The functions of the modem unit 3A and the protocol unit 3B shown in FIG. 1B included in the signal processing device 3 are necessary for reconstructing the function of the mobile radio communication apparatus. By dividing the function of the signal processing device 3 into the modem unit 3A and the protocol unit 3B in this way, it becomes easy to share the same function in a plurality of wireless communication systems.

  Furthermore, the functions of the modem unit 3A and the protocol unit 3B shown in FIG. 1B included in the signal processing device 3 can be freely reconfigured because the mobile radio communication apparatus can move between service areas of different radio communication systems. It is useful when it is used. That is, the mobile radio communication device can select a radio communication system that can be optimally used according to the reception state of radio waves at the destination and the congestion level of the radio channel, and can perform communication under the selected system. . This facilitates roaming and handover.

As shown in FIG. 4, the general-purpose processor (CPU) 31 functions as a program sequencer (PS) 41 and an arithmetic unit (ALU) 42 that manage program execution. The signal processing unit (SPU) 32 shown in FIG. 3A performs signal processing in accordance with the start or end of processing itself or a programmed sequence, and supplies a trigger signal or an interrupt signal to the CPU 31. . The trigger signal or interrupt signal supplied to the CPU 31 is detected by the PS 41. Thereby, the CPU 31 can recognize the state of the SPU 32, for example, “end of signal processing”, and change the processing content of the ALU 42 based on the recognition.
As described above, by causing the CPU 31 and the SPU 32 to cooperate and share processing, it is possible to execute complicated calculations at high speed.

  As shown in FIG. 5, the SPU 32 includes an arithmetic logic unit (ALU) 51, an instruction memory 52, a data memory 53, and an input / output interface 54. The ALU 51 performs “correlation calculation”, “complex number calculation”, “array conversion”, “maximum value detection”, “memory address conversion” in accordance with input data from the outside, data in the memory 33 and processing instructions and data from the CPU 31. Advanced signal processing such as “sequencer” and “high-speed input / output”. The processing result from the ALU 51 is written in the data memory 33, the memory and register in the CPU 31, the memory 33, and the input / output interface 34. As described above, the high-level signal processing that is heavy for processing by the CPU 11 is performed by the SPU 12 that is a dedicated processor, thereby reducing the burden on the CPU 11 and improving the processing speed.

  FIG. 6 shows an address conversion circuit for the SPU 32. The address conversion circuit is composed of two address decoders 61 and 62 of the memory 60, and a required conversion pattern is written in each. One of the address decoders 61 and 62 is selected by an instruction from the SPU 32, and the decoding contents are switched. The register group 63 in the memory 60 is a memory cell in the memory such as a RAM (Random Access Memory). The decode contents of the write address decoder and the read address decoder provided in the normal RAM are the same. Therefore, if bit array conversion processing such as bit interleaving included in the processing of the SPU 32 is to be realized by a normal RAM, it is necessary to perform address calculation for each reading.

  According to FIG. 6, if the address decoders 61 and 62 are used as a write address decoder and a read address decoder, respectively, such an address calculation becomes unnecessary, and conversion processing such as interleaving with a large amount of processing can be performed at high speed. Can do. The address decoders 61 and 62 may be rewritable devices such as RAMs, and the address conversion table may be written to them. Thereby, since it can respond to a plurality of conversion patterns, flexible processing corresponding to various patterns can be realized with a simple configuration.

  As shown in FIG. 3A, data can be exchanged directly between the CPU 31 and the SPU 32 via the register array 36 in the CPU 31. Register array 36 is accessed directly from SPU 32. That is, the SPU 32 can directly write the data output from itself to the register array 36 and can directly read the data from the register array 36. The CPU 31 can capture the contents of the register array 36 and write data to the register array 36.

  As described above, when the register array 36 is used for data exchange between the CPU 31 and the SPU 32, the CPU 31 may access the register array 36 regardless of the operation status of the SPU 32 in the data exchange. Therefore, the data transfer process in the CPU 31 can be speeded up, and the processing of the signal processing device 3 can be speeded up.

  The operation in the case where the signal processing device 3 shown in FIG. 3A receives and processes the digitized reception IF signal from the wireless transmission / reception device 2 by the input / output interface 34 will be described. If the received signal is to be processed only by the CPU, much of the CPU's computing power is consumed only by input / output processing, and only the remaining capacity of the CPU can be directed to other processing. According to the signal processing device 3 shown in FIG. 3A, the processing capacity of the CPU 31 is applied to processing other than the input / output processing by causing the SPU 32 to perform the input / output processing without using the CPU 31 using the register array 36. be able to.

  The reception IF signal fetched by the input / output interface 34 is sequentially fetched by the SPU 32, and if a fixed process is necessary, the SPU 32 performs a required signal process. The processing result from the SPU 32 is written into the memory 33 or the register array 36. The CPU 31 performs necessary processing using data written in the memory 33 or the register array 36.

  In this way, by allowing the SPU 32 to share input / output processing and signal processing, the load on the CPU 31 can be reduced. In other words, by distributing the processing load of the signal processing device 3 to the CPU 31 and the SPU 32, the signal processing device 3 as a whole can realize high-speed signal processing. In order to further distribute the load, a plurality of CPUs may be provided, and the processing to be shared by the CPU 31 in FIG. 3A may be distributed to each CPU.

  Hereinafter, other embodiments of the present invention will be described. In the following embodiments, the basic configuration of the mobile radio communication apparatus is the same as that of the first embodiment, and other variations of the components or operation modes of the mobile radio communication apparatus are disclosed.

(Second Embodiment)
The signal processing device 3 shown in FIG. 7 includes a circuit configuration description memory 71, a program sequencer 72, a programmable hardware device 73, and a memory 74. The programmable hardware device 73 is hardware capable of redefining a circuit configuration such as PLD or FPGA (field programmable gate array), and is an aggregate of various logic circuits that perform basic operations of signal processing. The programmable hardware device 73 may be a device that realizes a required processing function by allowing a combination of various logic circuits to be changed programmably by a switch.

  The circuit configuration description memory 71 holds a circuit configuration description for each processing content for realizing a required signal processing function by combining various logic circuits in the programmable hardware device 73 in a programmable manner. The memory 74 stores a program that indicates a procedure of processing to be executed by the programmable hardware device 73.

  The program sequencer 72 receives the resource management program from the resource controller 4, reads the program from the memory 74, controls the circuit configuration description memory 71 and the programmable hardware device 73 accordingly, and performs signal processing according to the program. The program is executed by the programmable hardware device 73.

  In a processor such as a general CPU or DSP, the circuit configuration of the internal ALU portion is fixed. A dedicated circuit corresponding to each instruction set is configured as an ALU so that the processor can realize processing contents according to the given instruction set. On the other hand, the processing normally performed by the ALU in the present embodiment is realized by the programmable hardware device 73 whose circuit configuration can be redefined.

  The circuit configuration description memory 71 stores a circuit configuration description necessary for realizing a desired process in the programmable hardware device 73 as a program. More specifically, the circuit configuration description memory 71 has a circuit configuration for realizing basic processing such as “four rule operations”, “data transfer”, and “bit shift” included in a normal ALU by hardware. In addition to the description, for example, “correlation calculation processing”, “complex multiplication processing”, “maximum value detection processing”, “absolute value calculation”, and the like are realized in hardware by processing performed by a normal processor in multiple steps. And a program showing a circuit configuration description indicating a combination of basic arithmetic processing. By using such a circuit configuration description memory 71, each time a signal processing function of the signal processing device 3 is newly defined, the circuit configuration description of the programmable hardware device 73 is changed so that the signal processing function can be realized. The

  In the program area 74A on the memory 74, a number of programs for performing the circuit configuration description as described above for the memory 71 are described. A necessary program is read from the block area 74 </ b> A under the control of the program sequencer 72 and given to the circuit configuration description memory 71. As a result, the circuit configuration of the programmable hardware device 73 is redefined.

  Thus, according to the present embodiment, the processing of the signal processing device 3 is realized by the programmable hardware device 73 whose circuit configuration can be redefined. Therefore, an ordinary processor that performs software processing can perform processing that requires tens to hundreds of steps at high speed within a few cycles, and can flexibly cope with the definition of various signal processing functions.

(Third embodiment)
In the signal processing device 3 shown in FIG. 8, a CPU 75 is added in addition to FIG. The circuit configuration description memory 71, the program sequencer 72, the programmable hardware device 73, and the memory 74 are basically the same as those described with reference to FIG. However, here, the program sequencer 72 further selects a device corresponding to the processing contents so that the programmable hardware device 73 performs predetermined complicated signal processing and the CPU 75 performs normal signal processing. A function and a function of performing a parallel processing by operating the programmable hardware device 73 and the CPU 75 at the same time.

  In particular, in the signal processing of the modem unit 3A shown in FIG. 1B of the signal processing device 3, the signal processing device 3 should have the resource management program from the resource controller 4 executed by the program sequencer 72. In accordance with the signal processing function, the sharing of processing to be performed by the programmable hardware device 73 and the CPU 75 is determined. The circuit configuration description selected from the memory 71 according to this determination is given to the programmable hardware device 73. At the same time, the CPU 75 is instructed by the program sequencer 72 to execute the processing to be shared by the CPU 75.

  By the control as described above by the program sequencer 72, signal processing complicated and heavy for the CPU 75 is performed by the programmable hardware device 73 which is a processor dedicated to signal processing, and other processing is performed by the CPU 75. Accordingly, high-speed processing is possible, and it is possible to easily cope with signal processing functions and design changes that the signal processing device 3 should have, and the time required for developing a new product of the mobile radio communication device is shortened.

(Fourth embodiment)
The signal processing device 3 shown in FIG. 9 is different from the configuration shown in FIG. 7 in that it has two programmable hardware devices 73A and 73B. The program sequencer 72 is added with a function of performing control to share processing with the programmable hardware devices 73A and 73B. With such a configuration, the processing function of the signal processing device 3 can be changed with a higher degree of freedom, and more complicated signal processing can be executed. The configuration of this embodiment may be expanded to have three or more programmable hardware devices.

  FIG. 10 shows the signal processing device 3 shown in FIG. 9 more specifically. The program memory 80 and the data memory 81 correspond to program areas 74A and 74B in the memory 74, the control circuit 92 corresponds to the program sequencer 72, the circuit description memory 83 corresponds to the circuit configuration description memory 71, and the SPU 84 corresponds to the programmable hardware device 73, respectively. To do.

  An instruction or data from the external device, that is, the resource controller 4 or the system controller 6 in FIG. 1A is taken into the signal processing device 3 through the input register group 85 and is passed to the register group 86 to be temporarily held. Then, it is sent to the output register group 87 and passed to the SPU 84.

Assume that the following processing program is stored in the program memory 81, for example.
a = A + B (i)
b = C × D (ii)
(A, b) = (A, B) * (C, D) (iii)
These processing programs (i), (ii) and (iii) represent addition, multiplication and complex multiplication, respectively. X and Y in (X, Y) represent the elements of the real part and imaginary part of the complex number, respectively. * Represents complex multiplication.

  In the circuit configuration description memory 83, circuit configuration descriptions for realizing the respective operations are recorded. The control circuit 82 stores the circuit configuration description memory 83 in accordance with the contents of the program stored in the program memory 80. By accessing, the circuit configuration description of the SPU 84 that is a programmable hardware device is rewritten. Therefore, in the example of the processing program described above, an adder circuit, a multiplier circuit, and a complex multiplier circuit are formed in the SPU 84. The signal processing performed by the SPU 84 is not limited to addition / subtraction / multiplication / division, and any processing is possible as long as the circuit configuration can be described, such as correlation calculation and maximum / minimum value determination. As the processing becomes extremely complicated, the processing efficiency is improved by recombination with a hardware configuration dedicated to the processing, so that a further high-speed processing effect can be enjoyed.

(Fifth embodiment)
As shown in FIG. 11, the signal processing device 3 according to the fifth embodiment of the present invention has, as hardware resources, an area 3A in which the signal processing function cannot be redefined, an area 3B in which the signal processing function cannot be redefined, and a switch unit (SW). 110. In the non-redefinable region 3A, frequently used logic circuits such as a CRC attach block 101, a CRC check block 102, a Viterbi decoder 103, a turbo decoder 104, a correlator 105, an accumulator 106, a demodulator 107, and a demodulator are provided. An interleaver 108 is implemented. The redefinable area 3B includes a plurality of PLDs 109 that are components of the FPGA. The switch unit 110 switches the connection between the region 3A and the region 3B and the connection of each block in the region 3B by control from the resource controller 4.

  12 and 13 show a connection state corresponding to a single wireless communication system realized by switching the switch unit 110 of the signal processing device 3 shown in FIG. The received signal input to the signal processing device 3 is input to the correlator 105 and the demodulator 07, and the output signal from the correlator 105 is input to the accumulator 106. An output signal from the accumulator 106 is input to the demodulator 107. An output signal from the demodulator 107 is used as an output signal of the signal processing device 3 via the deinterleaver 108, the Viterbi decoder 103, and the CRC check block 102. In FIG. 13, an equalizer 111 assigned with a function to the PLD 109 is added to FIG. The input signal is input to the demodulator 107 via the equalizer 111.

  FIG. 14 shows a connection example in which the signal processing device 3 is compatible with the two wireless communication systems A and B. The demodulator 107 is commonly used in both the systems A and B. In both systems A and B, the output signal from demodulator 107 is input to deinterleaver 108, and the output signal from deinterleaver 108 is input to Viterbi decoder 103 in system A and to turbo decoder 104 in system B. The Output signals from the Viterbi decoder 103 and the turbo decoder 104 are output from the signal processing device 3 via the CRC check block 102.

  The resource size of the signal processing device 3, particularly the size of the areas 3 </ b> A and 3 </ b> B, differs for each mobile radio communication apparatus. In a mobile radio communication apparatus in which several application service functions are installed, many signal processing functions are already defined in the resources of the signal processing device 3. The amount of surplus resources of the signal processing device 3 changes from moment to moment according to the usage status of the mobile radio communication apparatus.

  As shown in FIG. 15, the resource controller 4 includes a resource management table 130, a resource manager 131, an update system 132 that updates resources of the signal processing device 3, a buffer 133 for temporarily storing various data, and a signal A resource monitoring system 134 for monitoring the resource usage status of the processing device 3 is provided.

  The resource manager 131 updates the resource management table 130 that is a resource usage list based on the monitoring result from the resource monitoring system 134. The resource manager 131 grasps the surplus resource amount in the redefinable area 3B of the signal processing device 3 by referring to the resource management table 130 or based on the monitoring result from the resource monitoring system 134.

  Based on the configuration description information for realizing a new signal processing function that is additionally defined in the resource of the signal processing device 3, the resource manager 131 is a resource required in the redefinable area 3B to define the function. Know the amount. The resource manager 131 uses the resource update device 132 to add a new signal processing function to the redefinable area 3B of the resource of the signal processing device 3 according to the required resource amount and the surplus resource amount.

  According to the present embodiment, even if the mobile radio communication apparatus has an environment in which the resources of the signal processing device 3 owned and the usage status of the resources are different, the efficiency depends on the usage status of the resource that changes every moment. Thus, it becomes possible to add a new signal processing function. In other words, by adding a new signal processing function using information on the status of resources already used by itself, it is possible to optimally allocate resources.

  FIG. 16 shows a configuration of a radio communication system including mobile radio communication apparatus 10 according to the present embodiment as a terminal. In this wireless communication system, a configuration description information providing apparatus 140 exists in a base station. The configuration description information providing apparatus 140 describes information (hereinafter referred to as configuration description information) describing the configuration of the signal processing function to be additionally defined in the resource of the signal processing device 3 in the mobile radio communication apparatus 10 as the mobile radio communication apparatus 10. To provide.

  In this example, the configuration description information providing apparatus 140 includes an antenna 141, a wireless transmission / reception device 142, and a buffer 143 for storing the configuration description information in order to provide the configuration description information to the mobile radio communication apparatus 10 by radio communication. . Communication between the mobile radio communication device 10 and the configuration description information providing device 140 may be wired. For example, in a service center that updates the function of the mobile radio communication device 10, the configuration description information providing device 140 may be used as a device that performs the function update.

  As shown in FIG. 1, the mobile radio communication apparatus 10 includes an antenna 1, a radio transmission / reception device 2, a signal processing device 3, a resource controller 4 storage device 5, a system controller 6, and an input / output device unit 7. As shown in FIG. 15, the resource controller 4 includes a resource management table 130, a resource manager 131, a resource update system 132, a buffer 133, and a resource monitor system 134 for monitoring the resource usage status of the signal processing device 3. .

  In the configuration description information providing apparatus 140, configuration description information corresponding to the signal processing function newly added to the wireless communication apparatus 10 is read from the buffer 143. The read configuration description information is transmitted to the mobile radio communication apparatus 10 by the radio transmission / reception device 142. The configuration description information transmitted to the mobile radio communication apparatus 10 is received by the radio transmission / reception device 2. The resource controller 4 grasps the required resource amount for the signal processing device 3 to realize a desired signal processing function based on the received configuration description information. In the resource controller 4, the unused resource amount that is not used by the signal processing device 3 is grasped based on the usage status of the resources monitored by the resource monitor system 134. The resource controller 4 performs optimal resource allocation for the signal processing function to be additionally defined in the resources of the signal processing device 3 according to the required resource amount and the surplus resource amount.

  FIG. 17 shows another configuration of the wireless communication system including the mobile wireless communication device 10 according to the present embodiment. The configuration description information providing apparatus 140 further includes a resource controller 144 in addition to the antenna 141, the wireless transmission / reception device 142, and the buffer 143 described with reference to FIG. Information indicating the resource usage status of the signal processing device 3 monitored by the resource monitoring system 134 when a new signal processing function should be additionally defined in the resource of the signal processing device 3 in the mobile radio communication apparatus 10 Is transmitted to the configuration description information providing apparatus 140 via the antenna 1 by the wireless transmission / reception device 2.

  In the configuration description information providing apparatus 140, configuration description information indicating a signal processing function to be newly defined in the signal processing device 3 is read from the buffer 143. Based on the configuration description information, the resource controller 144 grasps a required resource amount for additionally defining a new signal processing function in the resource of the signal processing device 3. Further, the resource controller 144 grasps the surplus resource amount of the signal processing device 3 based on the usage status of the resources monitored by the resource monitor system 134. The resource controller 144 calculates an optimal resource allocation for the signal processing function additionally defined in the resources of the signal processing device 3 according to the required resource amount and the surplus resource amount, and outputs resource allocation instruction information. This resource allocation instruction information is transmitted to the mobile radio communication apparatus 10 via the antenna 141 by the radio transmission / reception device 142.

  The resource allocation information transmitted to the mobile radio communication apparatus 10 is received by the radio transmission / reception device 2 via the antenna 1 and passed to the resource controller 4. The resource controller 4 performs optimal resource allocation for the signal processing function to be additionally defined in the resource of the signal processing device 3 according to the resource allocation information. Thus, the calculation for resource allocation is executed by the configuration description information providing apparatus 140. That is, a calculation required for adding a new signal processing function to the resource of the signal processing device 3 in the mobile radio communication apparatus 10 is performed outside the mobile radio communication apparatus 10. As a result, the amount of calculation performed by the resource controller 4 of the mobile radio communication device 10 is reduced, which can contribute to cost reduction of the mobile radio communication device 10. That is, the processing load required for resource allocation of the signal processing device 3 of the terminal is assisted by the base station, thereby reducing the processing load on the terminal required for resource allocation.

  The operation of the present embodiment will be described with reference to FIGS. Referring to FIG. 18, first, the mobile radio communication apparatus 10 receives configuration description information transmitted from the configuration description information providing apparatus 140 (step S101). In the mobile radio communication apparatus 10, the resource controller 4 uses the received configuration description information to obtain a required resource amount required for additional definition of the signal processing function to the signal processing device 3 (step S102). The required resource amount is compared with the resource amount (initial resource amount) that the signal processing device 3 has at the time of shipment of the mobile radio communication apparatus 10 (step S103). If the required resource amount is larger than the initial resource amount, the configuration description information providing apparatus 140 is notified that additional definition of the signal processing function is impossible (step S104).

  If the required resource amount is smaller than the initial resource amount, the resource controller 4 grasps the current resource usage status of the signal processing device 3, for example, the surplus resource amount, by the resource monitor system 134 (step S105). The surplus source amount and the required resource amount are compared, and it is determined whether or not a new signal processing function can be additionally defined in the signal processing device 3 (step S106). When the additional definition is possible, the resource update system 132 defines a new signal processing function as the resource of the signal processing device 3 (step S107). In step S107, the resource allocation of the signal processing function already defined in the signal processing device 3 is changed as necessary. If additional definition of a new signal processing function is impossible, the fact is notified to the configuration description information providing apparatus 140 (step S104). The process of step S103 may be omitted.

  Referring to FIG. 19, the process from step S201 to S204 is the same as the process from step SS101 to S104 in FIG. In step S <b> 205, the current resource usage status of the signal processing device 3, for example, the surplus resource amount is grasped by referring to the resource management table 130. In the next step S206, it is determined whether or not the signal processing device 3 can additionally define a new signal processing function. If additional definition is possible, the resource update system 132 defines a new signal processing function in the resource of the signal processing device 3 (step S207), and updates the resource management table 130 accordingly (step S208). .

  According to FIG. 20, the processing of steps S301 to S305 and steps S307 and S308 are the same as the processing of steps SS201 to S204 and the processing of steps S206 and S207 in FIG. In FIG. 20, after the process of step S305, the resource management table 130 is updated in step S306 before a new signal processing function is defined in the resource of the signal processing device 3 in step S307.

  As described above, the resource size of the signal processing device 3 is generally different for each mobile radio communication apparatus. Accordingly, the configurations and sizes of the non-redefinable area 3A and the redefinable area 3B illustrated in FIG. 11 are different for each mobile radio communication apparatus. Therefore, in order to efficiently allocate resources for the signal processing function of the signal processing device 3, details of the resources of the signal processing device 3, such as the number of CRC additional blocks 101 and CRC check blocks 102 in FIG. There is a need to.

  In the wireless communication system shown in FIG. 17, a resource controller 144 is provided in the configuration description information providing apparatus 140 that is an apparatus other than the mobile wireless communication apparatus 10 having the signal processing device 3. When the resource controller 144 performs an operation necessary for additionally defining a new signal processing function for the resource of the signal processing device 3 in the signal mobile radio communication apparatus 10, the resource controller 144 performs the signal processing device 3. You need to be able to understand the details of your resources.

  Hereinafter, taking the radio communication system of FIG. 17 in which the configuration description information providing apparatus 140 is provided in the base station and the mobile radio communication apparatus 10 is a terminal as an example, the resources of the signal processing device 3 in the mobile radio communication apparatus 10 (hereinafter, A method for grasping the details of the terminal resource in the base station will be described.

  As shown in FIG. 21, the layer configuration (L1 / L2: layer 1 / layer 2) in a normal base station has a data link control (DLC) and a physical layer (PHY). The DLC includes a media access control (MAC), an error control block (EC), and a radio resource controller (RRC). In the base station, an error control block (EC) receives data transmitted from an upper layer, and performs signal processing so as to have resistance against errors occurring in the wireless transmission / reception device. The signal output from the error control block (EC) is sent to the media access control (MAC). The signal output from the MAC is sent to the physical layer (PHY). In PHY, signal processing for modulation is performed, and an RF signal to be used for wireless transmission is generated. EC, MAC and PHY are controlled by a radio resource controller (RRC). Conversely, when the base station receives a transmission signal from a terminal, processing is performed in the reverse order of the above-described signal flow.

  In FIG. 22, the layer structure in the base station of the radio | wireless communications system according to this embodiment is shown. In FIG. 22, a controller for controlling terminal resources is newly added to the L1 / L2 layer configuration shown in FIG. Specifically, TRC (Terminal Resource Control) is added as a component of DLC (Data Link Control). The TRC independently communicates with RRC (Radio Resource Control), thereby acquiring the machine number or model information of the terminal. That is, the TRC acquires the device number or model information of the terminal by monitoring the communication between the terminal and the base station.

  As one of the methods for grasping the resources owned by the terminal from the machine number or the terminal model information, there is a method using a table. An example of such a table is shown in FIG. In the table, a resource list showing details of terminal resources is referred to. In the resource list, as illustrated in FIG. 24, the function block name and the quantity of each function block are described, and further special items such as the simultaneous use being impossible are described. As described above, resources are divided into non-redefinable areas and redefinable areas.

  The TRC uses the information of the resource list as illustrated in FIG. 24 to grasp the required resource amount for defining a desired signal processing function in the terminal resource, obtains the optimal resource allocation by calculation, Output information. The resource allocation instruction information is transmitted from the base station to the terminal. The table shown in FIG. 23 is updated each time a new terminal is released.

  FIG. 25 shows the layer configuration of the base station (BS) and terminal (MT) according to the present embodiment. A TRC is provided in the base station BS, and a resource controller (RC) is provided in the terminal MT. The TRC has a resource list for each terminal. Terminal resources differ from terminal to terminal. The RC has a resource management table indicating the usage status of terminal resources. The ratio of the non-redefinable area and the redefinable area of the terminal resource differs for each terminal. The usage status of the terminal resource is monitored by the resource monitor system.

  The TRC provided in the base station BS communicates with the RC provided in the terminal MT, and acquires information on the usage status of terminal resources from the terminal. For example, the TRC transmits a message as illustrated in FIG. 26 to the RRC in order to grasp the usage status of the terminal resource. Upon receiving this message, the RRC of the base station BS requests the RC provided in the terminal MT to report the usage status of the terminal resource to the base station. Upon receipt of this request, the RC of the terminal MT updates the terminal resource usage status table and transmits the table to the base station BS. The TRC of the base station BS has a resource list of the terminal MT, and the list identifies the type and quantity of resources owned by the terminal MT. Therefore, the resource usage status table sent from the MT terminal to the base station BS is simplified to a table in which only numerical values are described according to a predetermined order as shown in FIG. The RRC that has received the resource usage status table transmits a message as shown in FIG. 28 to the TRC provided in the base station.

  Through the above procedure, the TRC can grasp the usage status of the terminal resource. Based on the information such as the machine number or the terminal model, the resource owned by the terminal is grasped, and the usage status of the terminal resource is acquired from the terminal. Further, the TRC calculates the optimum resource allocation required for the newly added function based on these information, and outputs the resource allocation instruction information. This resource allocation instruction information is transmitted from the base station to the terminal.

  In a terminal capable of changing the signal processing function, the resource usage changes sequentially. That is, a part of functions once set in the terminal may be unnecessary. Therefore, resource management based on the latest information can be performed by updating the resource management table at the time of adding a function.

  In order to notify the terminal that the signal processing function cannot be added, for example, in the wireless communication system shown in FIG. 16, an additional definition of the function is sent from the mobile wireless communication apparatus 10 to the configuration description information providing apparatus 140. What is necessary is just to add the mechanism which communicates that it was impossible. When trying to define additional signal processing functions, additional definitions of all the signal processing functions may lack resources. In such a case, the base station can grasp that the terminal side cannot add a new signal processing function. When the base station grasps this fact, the base station transmits configuration description information so that the terminal side can additionally define a minimum signal processing function according to the amount of surplus resources. With such a minimum additional definition, service improvement as a wireless communication system is achieved.

(Sixth embodiment)
FIG. 29 shows a mobile radio communication apparatus according to the sixth embodiment of the present invention. This mobile radio communication apparatus includes an antenna 1, a radio transmission / reception device 2, a signal processing device 3, a resource controller 4, and a storage device 5 as in the previous embodiments. In FIG. 29, the system controller 6 and the input / output device unit 7 shown in FIG. 1 are omitted.

  The signal processing device 3 is configured by a processor that performs signal processing in software, such as a CPU or a DSP, or a programmable hardware device such as a PLD. Taking the case where the signal processing device 3 is a processor as an example, the processor has a storage area such as a RAM area into which an execution program is read, and a module group constituting a program for performing signal processing in the storage area. Signal processing is executed by reading. The module here is a compiled executable file, and each signal processing function is made into a software module.

  The storage device 5 stores programs and data files. In particular, as a program, a group of modules whose specifications in the signal processing device 3 are assumed is stored. Thereby, a module group required when the mobile wireless communication apparatus is switched to another mode, for example, a mode for receiving another channel, can be read from the storage device 5 and passed to the signal processing device 3.

  FIG. 30 shows an example of the storage area of the signal processing device 3 and the contents of the storage device 5. The signal processing device 3 includes a DSP 210 as a processor, and an audio transmission module 211 and an audio reception module 212 are read in the storage area. The storage device 5 stores a data transmission module 221, an equalizer module 222, a Viterbi decoder module 223, and a CRC module 224.

  The resource controller 4 includes a source management table 200, a resource manager 201, a resource rewrite processor 202, and a download buffer 203. The resource management table 200 stores information on storage locations of modules that can be executed by the signal processing device 3. The resource manager 201 controls (a) the order in which resources are replaced, (b) the determination of whether to replace, and (c) the timing of replacement. The resource rewrite processor 202 rewrites the module to the processor of the signal processing device 3 stored in the storage device 5 according to an instruction from the resource manager 201. The download buffer 203 temporarily stores a module downloaded from the outside.

  The basic operation of the mobile radio communication apparatus according to the present embodiment is the same as that of the embodiments described so far, and the specific operation is as follows. It is assumed that the wireless transmission path between the mobile radio communication device and a base station (not shown) deteriorates due to shadowing, that is, the mobile radio communication device enters a shadow, and the desired communication quality is not satisfied. The communication quality is detected by, for example, an electric field measurement function that the wireless transmission / reception device 2 has.

  When the desired communication quality is not satisfied, the resource controller 4 determines that it is necessary to newly incorporate an equalizer module in the resource of the signal processing device 3 in order to improve the communication quality. Based on this determination, in the resource controller 4, if the signal processing device 3 has sufficient resources, the resource manager 201 performs control to incorporate the equalizer module into the resource. The resource manager 201 confirms whether an equalizer module exists in the storage device 5 by referring to the resource management table 200.

  As shown in FIG. 30, if there is an equalizer module 222 in the storage device 5, the resource controller 4 reads it into the signal processing device 3 as an execution file of the processor that is the signal processing device 3. If there is no equalizer module in the storage device 5, the resource controller 4 issues a download request, acquires the module, and stores it in the download buffer 203.

  When a module necessary for the signal processing device 3 in the mobile radio communication apparatus is not stored in the storage device 5, the download request is made to, for example, a base station having a service area in the area where the mobile radio communication apparatus is currently located. To be issued. The base station transfers the received download request to a network (not shown). The network transmits the requested module via the base station to the mobile radio communication apparatus that has issued the download request.

  Thus, the necessary signal processing function is defined in the signal processing device 3 by exchanging the programs held in the storage area of the processor which is the signal processing device 3. As a program, a necessary module is fetched only when necessary. As a result, it is possible to suppress wasteful use of resources, that is, unnecessary occupancy of memory resources due to modules that are normally unnecessary being resident in the storage area of the processor. Therefore, it is possible to cope with roaming and handoff between different wireless communication systems while effectively utilizing resources with limited capacity.

  Next, a more specific operation example of the mobile radio communication apparatus according to the present embodiment will be described. First, a case will be described in which the type of communication is switched, such as switching from a state in which the mobile wireless communication device is used for voice calls to a state in which data communication such as Web browsing is used.

  When the communication type is switched from, for example, voice communication to data communication, a voice call module, for example, a voice CODEC module is not necessary, and a module with a new TCP / IP is required instead. The resource manager 201 confirms whether or not the TCP / IP module exists in the storage device 5 with reference to the resource management table 200. If there is a TCP / IP module in the storage device 5, it is read into the storage area of the processor as an execution file of the processor which is the signal processing device 3. A voice call module such as a voice CODEC module that has become unnecessary is cleared from the storage area of the processor.

  If the TCP / IP module is not in the storage device 5, the resource manager 201 obtains it by downloading as described above. The acquired TCP / IP module is stored in the storage device 5 and then written in the resource management table 200. The resource manager 201 confirms again by the resource management table 200 whether the TCP / IP module exists in the storage device 5. If there is a TCP / IP module in the storage device 5, it is read as an executable file into the storage area of the processor. Thereby, data communication becomes possible thereafter.

  This operation will be described with reference to FIGS. As shown in FIG. 31, the voice transmission module 211 and the voice reception module 212 are read in the storage area of the signal processing device 3 as in FIG. 30. The storage device 5 stores a data transmission module 221, a data reception module 225, an audio transmission module 226, and an audio reception module 227.

  In the first step S401, the DSP 210 uses the voice transmission module 211 and the voice reception module 212 to perform signal processing for a voice call. In this state, it is assumed that the user of the mobile radio communication apparatus next operates the input / output device unit 7 shown in FIG. In response to this instruction, the resource controller 4 issues a resource update request (step S402). Thereby, the resource manager 201 of the resource controller 4 refers to the resource management table 200 and checks whether there is a data communication module in the storage device 5 (step S403). If there is no data communication module in the storage device 5, a download request is issued, and if there is, a rewrite start notification is sent to the DSP 210 (step S404). As a result, the DSP 210 stops the execution of the module currently in the storage area.

  Next, the resource controller 4 uses the rewrite processor 202 to delete the voice transmission module and the voice reception module currently in the storage area of the DSP 210, read the data transmission module and the data reception module from the storage device 5, and store the storage area of the DSP 210. (Step S405). When the rewriting process by the rewriting processor 202 is completed, the resource controller 4 notifies the DSP 210 of rewriting completion (step S406). Upon receiving the rewrite completion notification, the DSP 210 executes the data transmission module and the data reception module in the storage area, and performs signal processing for data communication (step S407).

  In this manner, modules in the storage area of the DSP 210 (memory resources possessed by the DSP 210) are replaced under the management of the resource controller 4. Thus, the signal processing function of the DSP 210 can be changed from the voice call function to the data communication function, and the signal processing function can be replaced by using the limited storage area of the DSP 210. Therefore, the occupation of memory resources by unnecessary modules can be suppressed.

  In the example of FIG. 33, a programmable hardware device such as a PLD 230 is used as the signal processing device 3 in place of the DSP. The PLD 230 is operated by a module group 231 (for example, modules A, B, C, and D), and a module group 240 (for example, modules A, B, and C) that is assumed to be used in the PLD 231 is stored in the storage device 5. , D, E, F,...) Are stored. The module referred to here is a module of a circuit configuration program (circuit configuration description), for example, a layout wiring diagram of a PLD.

  The operation will be described with reference to FIG. 34. First, the PLD 230 performs signal processing using modules A, B, C, and D for constructing a circuit configuration for performing signal processing for voice communication (step S501). ). In this state, it is assumed that the user wants to perform data communication and operates the input / output device unit 7 shown in FIG. In response to this instruction, the resource controller 4 issues a resource update request (step S502). The modules B, C, and D are assumed to be modules for constructing a circuit configuration related to signal processing necessary for both voice communication and data communication.

  In data communication, since it is stored in advance that the modules B, C, D, and E are necessary, the resource controller 4 needs to replace the module A with the module E by checking the current module configuration in the PLD 230. Know that. The resource manager 201 of the resource controller 4 refers to the resource management table 200 (step S503) and checks whether or not the storage device 5 has a module E for constructing a circuit configuration for performing signal processing for data communication. (Step S504).

  When the module E is in the storage device 5, the resource manager 201 gives the rewrite processor 202 an instruction to rewrite the module A in the module group 231 held in the PLD 230 to the module E. Upon receiving this rewrite instruction, the rewrite processor 202 sends a module rewrite start notification to the PLD 230 (step S505). As a result, the PLD 230 stops the process execution in the circuit configuration by the currently held module. Next, the rewrite processor 202 discards the module A held by the PLD 230, and instead reads the module E from the storage device 5 and replaces it with the module A (step S506).

  When the module rewriting process of the PLD 230 by the rewriting processor 202 is completed in this way, the resource controller 4 notifies the PLD 230 of the rewriting completion (Step S507). Upon receiving this rewrite completion notification, the PLD 230 constructs a circuit configuration using the newly held module group 231 (modules B, C, D, E), and uses the circuit configuration to perform signal processing for data communication. Is performed (step S508).

  On the other hand, if there is no module E in the storage device 5 in step S504, the resource controller 4 issues a download request (step S509). With this request, the module E is downloaded and temporarily stored in the download buffer 203. Thereafter, in step S505, the PLD 230 is notified of the start of rewriting (step S505). As a result, in step S506, the module E held in the download buffer 203 is read by the rewrite processor 202 and written to the PLD 230.

  In this way, the downloaded module E can be written into the PLD 230 while downloading or immediately after the download is completed, and it is possible to shift from voice call to data communication in a short time. The module acquired by downloading is not only temporarily stored in the download buffer 203 but also stored in the storage device 5 as necessary for use thereafter.

(Seventh embodiment)
In the sixth embodiment, when switching the signal processing function of the signal processing device 3, among the necessary modules, the module is replaced with an unnecessary module for realizing a new signal processing function. Each module group in which modules necessary for each application are set may be prepared, and when switching the signal processing function, the module groups may be replaced. Thereby, the signal processing function of the signal processing device 3 can be switched at high speed.

  FIG. 35 shows a mobile radio communication apparatus according to the seventh embodiment that performs such module group unit replacement. This mobile radio communication apparatus can be applied to a plurality of different radio communication systems. Accordingly, the storage device 5 stores module groups 241 and 242 for performing signal processing for communication in different wireless communication systems. These module groups 241 and 242 can be updated by replacing the storage device 5. The DSP 210 of the signal processing device 3 operates by reading the module group 213.

  Now, assuming that the mobile radio communication apparatus is currently communicating with the base station by the radio communication system X, it is necessary to communicate with the base station by the radio communication system Y in order to perform a handover in this state, for example. . In this case, the resource manager 201 determines that the mobile radio communication apparatus needs to communicate with the radio communication system Y, and controls the order in which the resources are exchanged, the judgment as to whether or not to exchange, the timing for the exchange, and the like. The resource manager 202 releases an unused module in the system X, and gives an instruction to the rewrite processor 202 to install a module for the system Y. Upon receiving this instruction, the rewrite processor 202 performs module rewrite processing from the storage device 5 to the DSP 210.

  Here, since the wireless communication system X is still in use, it is necessary to leave the module to be used among the module group for the system X written in the storage area of the DSP 210. Therefore, an unused module is checked, the module is released from the storage area of the DSP 210, and a module for the system Y is incorporated into a storage area as a surplus resource generated thereby. As a result, the mobile radio communication apparatus can communicate with both the radio communication systems X and Y.

  36, the module X1 to perform communication under the system Y from the state in which the DSP 210 performs signal processing using the modules X1, X2, X3, and X4 for performing communication under the system X. Will be described when the module Y1 is read by releasing.

  First, in step S601, modules X1, X2, X3, and X4 for performing communication under the system X are written in the storage area of the DSP 210. The DSP 210 uses the modules X1, X2, X3, and X4 to transmit signals. Processing is in progress. In this state, for example, when a handover occurs, the resource controller 4 generates a module update request (step S602). The resource manager 201 receives the module update request, refers to the resource management table 200, checks whether the storage device 5 has a module group for the communication system Y, and determines the configuration of the module group for the communication system X. A check is made (step S603).

  The resource manager 201 determines a module necessary for communication in the wireless communication system Y, determines which module group for the wireless communication system X is replaced, and determines the order in which the resources are replaced. As a result, the resource manager 201 determines that the module X1 is unnecessary, the module Y1 is necessary, and Y1 should be written after deleting X1. Furthermore, the resource manager 201 gives an instruction to the rewrite processor 202 to rewrite the module X1 in the module group 213 held in the DSP 210 to the module Y1. In response to this instruction, the rewrite processor 202 sends a module rewrite start notification to the DSP 210 (step S604). As a result, the DSP 210 stops the process execution by the currently held module.

  Next, the rewrite processor 202 discards the module X1 in the module group 213 held in the DSP 210, and instead reads the module Y1 from the storage device 5 and replaces it with the module X1 (step S605). When this rewriting process is completed, the resource controller 4 notifies the DSP 210 of the rewriting completion (step S606). Upon receiving this notification, the DSP 210 performs signal processing for data communication using the held module group 213 (modules X2, X3, X4, Y1) (step S607).

  In this way, by replacing the modules in the DSP 210 under the management of the resource controller 4, the module storage area (the memory resource having a limited capacity) of the DSP 210 can be used effectively under the communication system X until now. It is possible to perform communication that has been performed only in the communication systems X and Y. Thereby, the handover can be easily realized.

  With reference to FIG. 37, another operation example in the present embodiment will be described. It is assumed that the mobile radio communication apparatus is communicating under the radio communication system U. When a mobile radio communication apparatus performs a handover to communicate under another radio communication system V at a cell (ie, service area) boundary, resources of the DSP 210 that is a signal processing device used in the radio communication system U are The modules are partially replaced so that they are gradually used in the wireless communication system V. By doing so, soft handover between different wireless communication systems becomes possible.

  Specifically, the module read by the DSP 210 is gradually occupied by the system V from the state occupied by the system U. The module for the system V is used if it is stored in the storage device 5 in advance, and is acquired by downloading otherwise.

  In FIG. 37, a state in which communication is performed under the wireless communication system U (assuming that a handoff occurs and a module update request is generated in step S701 (step S702). In step S701, the DSP 210 stores data in the storage area. It is assumed that modules U1, U2, U3, U4 are written as the module group 213, and signal processing is performed using these modules.

  The resource manager 201 refers to the resource management table 200 that stores the storage locations of modules that can be executed by the DSP 210, determines the order in which resources are replaced, determines whether to replace them, and when to replace them, and rewrites based on these determinations. Rewrite start is notified to the processor 202 and the DSP 210 (steps S703 to S704). As a result, the DSP 210 stops the process execution in the module group 213 currently held. At this time, the module group 213 already written in the DSP 210 is a module U1, U2, U3, U4 for performing signal processing for communication under the system U, as shown in step S705. A module for performing signal processing for communication in the system V is not included.

  Therefore, the rewrite processor 202 first releases the storage area of the module U1 in order to gradually rewrite the module group 213 written in the DSP 210 under the control of the resource manager 202. Next, the rewrite processor 202 writes the module V1 read from the storage device 5 in the released area (step S706). Next, the rewrite processor 202 releases the storage area of the module U2, and writes the module V2 read from the storage device 5 in the released area (step S707). Similarly, next, the rewrite processor 202 releases the storage area of the module U3, and writes the module V3 read from the storage device 5 in the released area (step S708). Next, the rewrite processor 202 releases the storage area of the module U4, and writes the module V4 read from the storage device 5 in the released area (step S709).

  In this way, under the control of the resource manager 201, the rewrite processor 202 gradually rewrites the module in the storage area of the DSP 210. If all necessary are rewritten, the resource manager 201 notifies the DSP 210 of completion of rewriting (step S710). Receiving this notification, the DSP 210 performs data communication processing using the currently held module group 213 (modules V1, V2, V3, V4) (step S711).

  In this way, the module group 213 in the DSP 210 is gradually replaced in accordance with the required signal processing function under the management of the resource controller 4. This enables soft handover between different wireless communication systems while effectively utilizing the module storage area (memory resource with a limited capacity) of the DSP 210, that is, suppressing the occupation of resources by unnecessary modules.

(Eighth embodiment)
As shown in FIG. 38, in the mobile radio communication apparatus according to the seventh embodiment of the present invention, a common hardware resource 232 is prepared for the signal processing device 3 using a programmable hardware device, for example, a PLD 230. The common hardware device 232 may be hardware different from the PLD 230, or may be a part of the PLD 230, for example, the non-redefinable area 3A shown in FIG.

  When the mobile radio communication apparatus is communicating under a certain radio communication system, it may be necessary to monitor another radio communication system. In such a case, in this embodiment, a part of the module group 231 read into the PLD 230 is released, and a part of the module for the wireless communication system to be newly monitored is incorporated. The procedure for opening and incorporating may be the same as the procedure described in the seventh embodiment.

  The common hardware device 232 is a device commonly used for a plurality of wireless communication systems. Therefore, the device 232 is used in common under the radio communication system used for communication by the mobile radio communication apparatus and another radio communication system to be monitored. By using the common hardware device 232, the resource processing load of the PLD 230 is reduced.

  As described above, even in a configuration using a programmable hardware device such as the PLD 230 for the signal processing device 3, a module that is a circuit configuration description for changing the circuit configuration of the PLD 230 is required when monitoring the wireless communication system. Accordingly, by taking in or replacing the storage area of the PLD 230, occupation of resources of the PLD 230 by unnecessary modules can be suppressed, and resources can be effectively used.

(Ninth embodiment)
In the mobile radio communication apparatus according to the ninth embodiment of the present invention shown in FIG. 39, the signal processing device 3 stores an execution file 214 common to a plurality of radio communication systems. As described in the eighth embodiment, consider a case where a mobile radio communication apparatus monitors another radio communication system in a state where communication is performed under a radio communication system. In such a case, similar to the procedure described in the seventh embodiment, a part of the module group 213 read into the DSP 210 is released, and a part of the module for the wireless communication system to be newly monitored is incorporated.

  The fixed common execution file 214 is commonly used for each wireless communication system. Therefore, the execution file 214 is used in common under the radio communication system used for communication by the mobile radio communication apparatus and another radio communication system to be monitored. By using the common execution file 214, the resource processing load of the DSP 210 is reduced.

(Tenth embodiment)
According to the mobile radio communication apparatus according to the tenth embodiment of the present invention shown in FIG. 40A, the resource controller 4 has a module management table 300, a module manager 301, a module rewrite processor 302, and a download buffer 303. In this example, the signal processing device 3 includes a DSP 310 and a program memory 311 in which a program indicating a signal processing procedure of the DSP 310 (hereinafter referred to as a processing module) is stored. The signal processing device 3 may be realized by a programmable hardware device such as PLA or FPGA in place of the DSP, and in this case, a software module describing the circuit configuration of the programmable hardware device is processed in the program memory. Stored as a module.

  The module management table 300 records the storage status of processing modules used in the mobile radio communication apparatus, the allocation status of the processing modules to the resources of the signal processing device 3, and the usage history of the processing modules by the resource controller 4 itself. And used. The module management table 300 includes at least a module storage state table 3001, a module allocation state table 3002, and a module usage history table 3003 as shown in FIG.

  The storage state of the processing module is managed by a module storage state table 3001. The allocation status of processing modules to resources is managed by a module allocation status table 3002. Information on the usage history of the processing module including the allocation status information to the resource of the module and the storage status information is managed by the module usage history table 3003. The module manager 301 records processing module usage history information in the module management table 300, and uses the module management table 300 to store, delete, and update processing modules.

  The download buffer 303 is a buffer area used for temporarily storing the downloaded processing module when the processing module is downloaded from the wireless line. In response to an instruction from the module manager 301, the module rewrite processor 302 performs processing module assignment from the storage device 5 to the signal processing device 3, and notification of processing module rewrite start / end. The signal processing device 3 to which the processing module is assigned by the module rewrite processor 302 fetches the assigned processing module from the storage device 5 and executes the signal processing procedure described in the processing module.

  In FIG. 40A, a display device 321 and an input device 322 are shown as components of the input / output device unit 7. Further, an interface 8 and an external storage device 9 that can be connected to the mobile wireless communication device via the interface 8 are prepared as necessary.

  Next, the operation of the mobile radio communication device according to this embodiment will be described. Assume that the signal processing device 3 includes a DSP 310 and a program memory 311 as shown in FIG. Now, at the point where the user of the mobile radio communication device is located, two types of radio communication systems (referred to as system A and system B) provide services, and these radio communication systems are used by the mobile radio communication device. Suppose you are in a possible situation.

  In the mobile radio communication apparatus, it is assumed that the user designates using a desired radio communication system, for example, the A system, by operating the key of the input device 321. The A system use designation information generated by this operation is taken into the resource controller 4. The resource controller 4 refers to the module management table 300 and recognizes the storage state of the processing module required under the designated A system and the allocation state of the signal processing device 3 to the resource. As a result, if a necessary processing module is insufficient, a download request for the insufficient processing module is generated.

  The download request generated by the resource controller 4 is transmitted from the wireless transmission / reception device 2 to the base station via a control channel prepared as a channel common to each wireless communication system, for example. In the base station, the processing module indicated by the received download request is read from a server in the base station or a server provided on a network to which the base station is connected, and transmitted to the requesting mobile radio communication apparatus.

  The processing module transmitted from the base station to the mobile radio communication apparatus is received by the radio transmission / reception device 2 and passed to the resource controller 4. The processing module received, that is, downloaded, is temporarily stored in the download buffer 303 by the resource controller 4 and then transferred to and stored in the storage device 5.

  Next, in the resource controller 4, a processing module assignment request is issued from the module manager 301 to the module rewrite processor 302. The module rewrite processor 302 performs control to read a necessary processing module from the storage device 5 in accordance with the processing module allocation request and write it into the program memory 311 of the signal processing device 3. In the signal processing device 3, the DSP 310 executes the processing module written in the program memory 311, thereby realizing signal processing determined by the processing module. Therefore, the user of the mobile radio communication apparatus can use a new function by the processing module written in the program memory 311.

  The module manager 301 effectively uses the finite memory capacity of the program memory 311 as described below when performing a control of reading a necessary processing module from the storage device 5 and writing it to the program memory 311. With reference to the contents of the module usage history table 3003 recorded in the module management table 300, the order of replacement of the processing modules with respect to the program memory 311, determination of whether to replace, the replacement timing, and the like are controlled.

  The module manager 301 further performs control for deleting unnecessary processing modules among various processing modules held in the storage device 5 and upgrading the version of the held processing modules. As a result of this control, if the program memory 311 lacks processing modules necessary for the next processing in the signal processing device 3, the module manager 301 generates a processing module allocation request.

  The processing module allocation request is given to the module rewrite processor 302, and the necessary processing module is written in the program memory 311 by the processor 302. In the signal processing device 3, the processing module written in the program memory 311 is executed by the DSP 310. Thereby, the function realized by the processing module written in the program memory 311 is realized by the mobile radio communication apparatus. That is, a new function by the processing module newly written in the program memory 311 is added to the mobile radio communication apparatus.

  A plurality of processing modules can be written in the program memory 311 of the signal processing device 3. In the signal processing device 3, an arbitrary processing module is executed by the DSP 310 in a state where a plurality of processing modules coexist in the program memory 311. The capacity of the program memory 311 and the capacity of the storage device 5 are both finite. Since the module manager 301 controls the order in which the processing modules in the signal processing device 3 are replaced, the determination of whether to replace them, and the replacement timing, the situation in which the capacity of the program memory 311 is insufficient can be suppressed.

  If the mobile radio communication device downloads a new processing module each time the processing module is stored in the storage device 5, the free storage area of the storage device 5 may eventually become insufficient. When there is no more free storage area in the storage device 5, it is necessary to secure other storage modules by deleting other processing modules stored in the storage device 5. In that case, it is desirable to delete the processing module that is not necessary for the mobile radio communication apparatus, that is, the processing module that has a low probability of being used in the mobile radio communication apparatus next time. For this reason, the use frequency of the processing modules used in the past is constantly monitored by the module manager 301, and the monitoring result is recorded in the module use history table 3003 of the module management table 300. The module manager 301 deletes the processing module with the lowest usage frequency on the module usage history table 3003. As a result, an empty storage area of the storage device 5 is secured, and the downloaded new processing module is stored in the storage device 5.

  FIG. 41A shows a list of items described in the module usage history table 3003 in the module management table 300. Module usage history items include module name, module size, usage frequency, storage status, and allocation status. The module name is the name of the processing module. The module size is a capacity of the storage device 5 necessary for storing the processing module. The usage frequency is the number of times the processing module has been used in the mobile radio communication device. The storage state is information indicating a state in which the processing module is stored in the storage area. Specifically, if the processing module is stored, it is an address of the program memory 311; NO. The allocation state is information indicating whether or not the processing module is allocated to the program memory 311. The allocation status is ON if the processing module is allocated, and is OFF if it is not allocated.

  A processing module whose resource allocation state is OFF is stored in the storage device 5 but is not allocated to the program memory 311. A processing module to be deleted is selected from processing modules whose resource allocation state is OFF. When all the processing modules are allocated to the program memory 311, the processing module to be deleted is deleted after the allocation to the program memory 311 is released.

  FIG. 41B shows a specific content example of the module usage history table 3003. In this example, module names include QPSK modulation, correlator, convolutional coding, PN coding, and Walsh coding. Module size is 10200Byte, 15300Byte, 12900Byte, 25000Byte, 18000Byte, usage frequency is 320, 230, 202, 23, 98, respectively. The address is 0x3000, NO (where 0x indicates hexadecimal notation), and the assignment status is indicated as ON, ON, OFF, OFF, OFF, respectively.

  With reference to FIG. 42, a processing procedure for deleting unnecessary processing modules in the storage device 5 using the usage frequency information recorded in the module usage history table 3003 shown in FIG. 41B will be described. This processing procedure is executed by the module manager 301. When the deletion of the module is started (step S701), the usage frequency is referred to among the items recorded in the module usage history table 3003 (step S702). With this reference, the processing module with the lowest use frequency is searched for among the processing modules whose allocation state is OFF, and an instruction to delete the processing module from the storage device 5 is given to the resource controller 4. The resource controller 4 deletes the processing module instructed to be deleted from the storage device 5 (step S703). The module manager 301 deletes the history information of the deleted processing module from the module usage history table 3003 (step S704). The operations in steps S702 to S704 are repeated until it is determined in step S705 that the necessary free space has been secured.

  For example, according to the example of the contents of the module usage history table 300 shown in FIG. 41 (b), the usage frequency of Walsh encoding among convolutional encoding, PN encoding, and Walsh encoding, which are processing modules whose allocation state is OFF. Is the least. Therefore, this Walsh encoding processing module is deleted. The history information of the processing module of the Walsh code is deleted from the module usage history table 3003. When the necessary capacity is ensured in the storage device 5 in this way, the deletion of the processing module is finished (step S706). As a result, the contents of the module usage history table 3003 shown in FIG. 41 (b) are updated as shown in FIG. 41 (c).

  By deleting processing modules by the module manager 301 in such a procedure, processing modules that are frequently used, that is, processing modules that are likely to be used next are stored in the storage device 5. Therefore, the processing module that is highly likely to be used is not subjected to unnecessary download processing, thereby reducing the processing load on the mobile radio communication apparatus.

  Next, the case where the module use history table shown in FIGS. 43A to 43C is used will be described. As shown in FIG. 43A, a list of items described in the module usage history table 3003 is shown. As for the items of the module usage history, the usage frequency is replaced with the latest usage date and time. It is the same. Specifically, the latest use date and time is the latest time stamp when the processing module read from the storage device 5 is written in the program memory 311. As shown in FIG. 43 (b), the contents example of the module usage history table 3003 is 2005/04 / 14,2005 / 12 / 21,2003 / 05 / 04,2005 / 02 / 03,2005 as the usage update date. / 08/14, except that is entered, is the same as FIG. 41 (a).

  Referring to FIG. 44, a processing procedure for deleting unnecessary processing modules in the storage device 5 using the latest usage date / time information recorded in the module usage history table 3003 shown in FIG. To do. This processing procedure is executed by the module manager 301. When the deletion of the module is started (step S801), the latest use date and time is referred to among the items recorded in the module use history table 3003 (step S802). With this reference, the processing module having the oldest use date and time is searched for among the processing modules whose allocation state is “OFF”, and an instruction to delete the processing module from the storage device 5 is given to the resource controller 4. The resource controller 4 deletes the processing module instructed to be deleted from the storage device 5 (step S803). The module manager 301 deletes the history information of the deleted processing module from the module usage history table 3003 (step S804). The operations in steps S802 to S804 are repeated until it is determined in step S805 that the necessary free space has been secured in the storage device 5.

  For example, according to the example of the contents of the module usage history table 300 shown in FIG. 43 (b), the latest use of convolutional coding among convolutional coding, PN coding, and Walsh coding, which is a processing module whose allocation state is OFF. The date is the oldest. Therefore, the convolutional encoding processing module is deleted from the storage device 5, and the convolutional encoding processing module history information is deleted from the module use history table 3003. When the necessary capacity is secured in the storage device 5 in this way, the deletion of the processing module is finished (step S806). As a result, the contents of the module usage history table 3003 shown in FIG. 43 (b) are updated as shown in FIG. 43 (c).

  By deleting the processing module by the module manager 301 in such a procedure, the processing module with the latest use date and time, that is, the processing module that is likely to be used next is stored in the storage device 5. Therefore, the processing module that is highly likely to be used is not subjected to unnecessary download processing, thereby reducing the processing load on the mobile radio communication apparatus. Furthermore, when a mobile radio communication apparatus is used by a user whose usage status frequently changes, it is possible to add and delete processing modules without waste according to the usage status.

  Next, the case where the module use history table shown in FIGS. 45 (a) to 45 (c) is used will be described. As shown in the list of items described in the module usage history table 3003 in FIG. 45 (a), the items in the module usage history are the same as those in FIG. 41 (a) except that the usage frequency or the latest usage date / time is deleted. And it is the same as FIG. 43 (a).

  Referring to FIG. 46, a processing procedure for deleting unnecessary processing modules in the storage device 5 using the module size information recorded in the module usage history table 3003 shown in FIG. . This processing procedure is executed by the module manager 301. When the deletion of the module is started (step S901), the module size is referred to among the items recorded in the module use history table 3003 (step S902). With this reference, the processing module having the largest module size is searched for among the processing modules whose allocation state is “OFF”, and an instruction to delete the processing module from the storage device 5 is given to the resource controller 4.

  The resource controller 4 deletes the processing module instructed to be deleted from the storage device 5 (step S903). The module manager 301 deletes the history information of the deleted processing module from the module usage history table 3003 (step S904). The operations in steps S902 to S904 are repeated until it is determined in step S905 that the necessary free space has been secured.

  For example, according to the example of the contents of the module usage history table 300 shown in FIG. 45 (b), the module size of Walsh encoding among convolutional encoding, PN encoding, and Walsh encoding, which are processing modules whose allocation state is OFF. Is the largest. Accordingly, the Walsh encoding processing module is deleted from the storage device 5, and the Walsh encoding processing module history information is deleted from the module usage history table 3003. When the necessary capacity is secured in the storage device 5 in this way, the deletion of the processing module is finished (step S906). As a result, the contents of the module usage history table 3003 shown in FIG. 45 (b) are updated as shown in FIG. 45 (c).

  By deleting processing modules by the module manager 301 in such a procedure, processing modules whose allocation state is OFF and whose module size is large are sequentially deleted from the storage device 5. Therefore, a necessary free storage area is secured on the storage device 5. By deleting the processing module having the largest size, there is a high possibility that an area larger than the required storage area size will be secured on the storage device 5 by one deletion operation. As a result, the processing module can be deleted only a minimum number of times, and the processing load required for the deletion can be reduced.

  Next, an example in which the module usage history table 3003 is added with a function of checking and saving version information of processing modules used by the mobile radio communication apparatus will be described.

  As shown in FIG. 47A, a list of items described in the module usage history table 3003 is shown, except that the module usage history item has a version instead of the usage frequency or the latest usage date and time. This is the same as (a) and FIG. The version is revision information of the processing module. For example, as shown in FIG. 47 (b), the versions of QPSK modulation, correlator, convolutional coding, PN coding and Walsh coding are 2.1, 1.3, 3.1, 2.3 and 1 .8.

  Referring to FIG. 48, a processing procedure for updating the module in the storage device 5 to a newer version using the version information shown in FIG. 47B will be described. When the module update process starts and a module update request, that is, a new process module use request is input to the module manager 301 (steps S1001 to S1002). The module manager 301 refers to the contents of the module use history table 3003 in the module management table 300 (step S1003), and checks whether the necessary processing module exists in the storage device 5 (step S1004).

  If the necessary processing module does not exist in the storage device 5, a necessary version of the processing module is downloaded from the wireless line (step S1005) and stored in the storage device 5 (step 1006). As a result, a new version of the processing module is newly stored in the storage device 5, so that the module rewrite processor 302 next writes the necessary processing module including the new processing module in the storage device 5 in the program memory 311. (Step S1010).

  On the other hand, if the result of the check in step S1004 is that the necessary processing module exists in the storage device 5, the module manager 301 refers to the module usage history table 3003, and the version of the processing module in the storage device 5 and the actually required module. The version of the processing module is compared (step S1007). As a result of the comparison, if the version of the processing module in the storage device 5 is equal to the version of the required processing module, the required processing module is loaded from the storage device 5 and written in the program memory 311 (step S1010).

  If the version of the processing module stored in the storage device 5 is old as a result of the check in step S1007, the required version of the processing module is downloaded from the wireless line (step S1008), and the old version existing in the storage device 5 is downloaded. The processing module is replaced (step S1009). Since the processing module in the storage device 5 is now updated to the new version, the module rewrite processor 301 next writes the necessary processing module in the storage device 5 in the program memory 311 (step S1010). When the processing of step S1010 is performed, the version update processing of the processing module ends (step S1011).

  Here, for example, consider using a convolutional coding processing module that is not assigned to the program memory 311 in accordance with the content example of the module usage history table 3003 shown in FIG. The required version of the convolutional encoding processing module is 4.0. The module manager 301 refers to the module usage history table 3003 and knows that the convolutional coding processing module is stored in the storage device 5. From the module usage history table 3003, it can be seen that the version of the convolutional encoding processing module stored in the storage device 10 is 3.1 and is older than the required version 4.0.

  Therefore, the module manager 301 requests the wireless transmission / reception device 2 to download the version 4.0 convolutional coding processing module. Accordingly, the version 4.0 convolutional encoding processing module downloaded via the wireless transmission / reception device 2 is replaced with the original old processing module and stored in the recording device 5. At the same time, the module usage history table 3003 is updated. Thereafter, the new processing module is assigned to the program memory 311. In this way, each time the processing module is used, the required processing module and the version of the processing module stored in the storage unit 5 are compared. If the version of the processing module in the storage device 5 is old, the version is updated. The

  Next, an example in which the user who uses the mobile radio communication apparatus selects a processing module to be deleted and secures a free space in the storage device 5 will be described. In order to allow the user to select a processing module to be deleted by himself or to input a command to delete the selected processing module, the display device 321 and the input device 322 provided in the input / output device unit 7 Is used. As the input device 322, a key input device such as a keyboard, a cursor key, and a cross key, a touch panel installed on the display surface of the display device 321 or a pointing device is used. The display device 321 displays the module name, the module size, and the current allocation status of the currently held processing module when the user sets the mode for securing the free storage area in the storage device 5. . The user can select and designate a processing module to be deleted by viewing this display. For this purpose, the module manager 301 refers to the function of managing the module usage history table 3003 in the module management table 300 and the contents of the table 3003, and the module name of each processing module currently held in the storage device 5. And at least a function of extracting information on the module size and the current allocation state. The resource controller 4 displays the information extracted by the module manager 301 on the display device 321 and the processing module to be deleted specified by the user operating the input device 322 according to the display from the storage device 5. Has a function to delete.

  The module manager 301 (a) a function for monitoring whether or not there is a shortage of processing modules in the program memory 311; and (b) referring to the module usage history table 3003 when there is a shortage of processing modules, and processing in the program memory 311 It has a function of controlling the order of replacement of modules, determination of whether to replace them, and the timing of replacement, and (c) a function of controlling deletion and version upgrade of processing modules in the storage device 5. When a processing module assignment request is issued from the module manager 301 to the module rewriting processor 302, the processor 302 writes the processing module obtained by downloading via the wireless line or loading from the storage device 5 into the program memory 311. The signal processing procedure (processing module) written in the program memory 311 is executed by the DSP 310, whereby the function realized by the written processing module is realized by the mobile radio communication apparatus.

  The module name in the module usage history table 3003 is accompanied by information on the file capacity of the corresponding processing module. When the module manager 301 assigns a processing module to the program memory 311 or replaces the processing module using the file capacity information, the module manager 301 rewrites the information on the allocation status of the corresponding processing module in the module usage history table 3003. It has a function to grasp. In accordance with this function, the module manager 301 acquires information to be displayed on the display device 321 with reference to the module usage history table 3003 when the mode for managing the free capacity of the storage device 5 is set. The resource controller 4 causes the display device 321 to display the information acquired by the module manager 301 in a predetermined format.

  The input operation result by the user from the input device 322 is recognized by the resource controller 4 which is a CPU. Based on this recognition result, the resource controller 4 shifts to the selected mode, selects and designates the module name, and deletes the processing module of the selected module name from the storage device 5.

  The user can replace the processing module by inputting an instruction to select a desired wireless communication system via the input device 322. When the user designates the use of a certain wireless communication system, for example, the A system via the input device 322, this designation information is taken into the resource controller 4. The module manager 301 refers to the module management table 300 including the contents of the module usage history table 3003 and knows information on processing modules required in the designated A system from the module management table 300.

  The module manager 301 knows the storage status of the currently used processing module and the allocation status to the resource (program memory 311) of the signal processing device 3 from the information in the module management table 300, and the processing module is insufficient. If it is recognized, a download request for the missing processing module is generated. The download request is sent from the resource controller 4 to the base station via the wireless transmission / reception device 2. The base station reads the processing module indicated by the received download request from the server and transmits it to the requesting mobile radio communication apparatus.

  The processing module transmitted from the base station to the mobile radio communication apparatus is received by the radio transmission / reception device 2 and passed to the resource controller 4. The processing module received, that is, downloaded, is temporarily held in the download buffer 303 by the resource controller 4. At this time, the free capacity of the storage device 5 is checked by the resource controller 4. As a result of this check, if there is sufficient free space for storing the processing module held in the download buffer 303, the processing module is read from the download buffer 303 and stored in the storage device 5. Accordingly, the contents of the module usage history table 3003 are updated by the module manager 301.

  If the storage device 5 does not have enough free space as a result of the above check, the storage area is secured by deleting other processing modules stored in the storage device 5 by the module manager 301 and then downloaded. The processing module read from the buffer 303 is held in the storage device 5. That is, when the free space of the storage device 5 is insufficient or when a request for securing the free space is generated, the module manager 301 refers to the contents of the module usage history table 3003 and stores all of the storage device 5. Extract the information of the processing module. The display device 321 is controlled by the module manager 301 based on the information, and the module name, module size, and status (current usage status) of the processing modules are displayed in a list. From this display, the user can know the module names and capacities of the processing modules currently held in the storage device 5 and whether each processing module is being used. From the display, the user searches for a processing module whose status is not in use, that is, whose allocation status is OFF. When the user finds a processing module whose assignment state is OFF, the user selects a desired module using the input device 322, and further instructs to delete the selected processing module. In accordance with this instruction, the resource controller 4 deletes the corresponding processing module in the storage device 5. Further, the module manager 301 deletes information regarding the deleted processing module from the module usage history table 3003.

  The above processing flow will be described with reference to FIG. For example, when the user designates a mode for deleting unnecessary processing modules by operating the input device 322, the module manager 301 executes the processing in FIG. When module deletion starts (step S1101), the module manager 301 refers to the module usage history table 3003 (step S1102), extracts necessary information from the information recorded in the table 3003, and displays it. The information is displayed on the device 321 (step S1103). When the user selects and designates a processing module to be deleted from the display content by operating the input device 322 (step S1104), the module manager 301 deletes the selected processing module from the storage device 5 (step S1105). .

  50A and 50B show a list of items described in the module usage history table 3003 and specific examples of the contents of the table 3003, similar to the examples given so far. . FIG. 50C shows an example of a history information display screen on the display device 321 in step S1103. In this display screen example, the module name of the processing module currently stored in the storage device 5, the size of the module, and the current state are displayed. The state indicates whether or not the corresponding processing module is being used in the mobile radio communication apparatus. If the state is not in use, “-” is displayed.

  The processing module to be deleted is designated by inputting a number indicating the name of the module to be deleted with the input device 322 at the bottom of the display screen in FIG. Thereafter, when a confirmation instruction operation is performed, the designated processing module is deleted from the storage device 5 by the module rewrite processor 302 controlled by the module manager 4. As the processing module to be deleted, it is desirable to designate one of the processing modules whose allocation status is OFF. If there is no processing module whose allocation state is OFF, one module appropriately selected from the processing modules whose allocation state is ON may be selected, and the processing module may be released and then deleted.

When the processing module designated in this way is deleted, the contents of the module usage history table 3003 are updated by the module manager 301 (step S1106). The operations in steps S1102 to 1106 are repeated until it is determined in step S1107 that the necessary free space has been secured in the storage device 5. If the necessary free space is secured, the deletion of the processing module ends (step S1108).
In this way, information regarding the processing modules stored in the storage device 5 is displayed on the display device 321, and the user of the mobile wireless communication device refers to this to select a processing module to be deleted, thereby obtaining a signal. The signal processing function of the processing device 3 can be selected. Therefore, it is possible to customize the mobile radio communication device with a function suitable for the user's usage mode.

  In the above description, the processing modules necessary for the mobile radio communication apparatus are supplied from the network side via download from the radio line, that is, the base station. On the other hand, as shown in FIG. 40A, a large-capacity external storage device 9 can be connected to the mobile radio communication device via the interface 8, and necessary processing modules are transferred from the external storage device 9 to the mobile radio communication device. It is also possible to take in the storage device 5. As a result, when the mobile wireless communication device requires a processing module that is insufficient or a new version of the processing module, the mobile wireless communication device can be downloaded from other than the wireless line, and the external storage device 9 can store the storage device 5 in the mobile wireless communication device By transferring and storing the processing modules stored in the database, it is possible to back up important processing modules. As the external storage device 9, for example, a semiconductor memory card, hard disk drive, MO (magneto-optical disk drive), CD-ROM drive, CD-R / RW drive, DVD drive, or the like is used.

  In the above description, deletion of a processing module in the storage device 5 is based on one of a plurality of items (for example, usage frequency, latest usage date and time, and module size) recorded in the module usage history table 3003. Done. On the other hand, the user of the mobile radio communication apparatus may be able to select an arbitrary item as a reference for deleting the processing module from the plurality of recorded items. As a result, the user can manage the processing modules according to various usage forms.

(Eleventh embodiment)
FIG. 51 shows a mobile radio communication apparatus according to the eleventh embodiment of the present invention. In each of the following embodiments, for simplicity, for example, two wireless communication systems (A system and B system) provide services, and the mobile wireless communication apparatus is an arbitrary system of the A system and the B system. It is assumed that it can be used after moving to. The A system and the B system are wireless communication systems provided by communication carriers A and B, respectively. The mobile radio communication apparatus shown in FIG. 51 makes it possible to use one telephone directory as a telephone directory file having a format dedicated to application software unique to each system in the A system and the B system.

  The signal processing device 2 includes a DSP 310 and an execution file storage unit 311 that stores a modulation / demodulation execution file (processing module) that can be directly executed by the DSP 310. The resource controller 4 includes a CPU 401 and a RAM 402 that records the current management status of resources of the signal processing device 2. The input / output device unit 7 includes a display for displaying various types of information to the user, and an input device such as a keyboard and cursor keys for the user to input operations.

  The storage device 5 includes an execution file 501 and a unique telephone number file 503 for the call management system A, an execution file 502 and a unique telephone number file 504 for the call management system B, a common telephone number file 510, a translator A511, and a translator B512. Stored.

  The call management system A execution file 501 is application software used only in the A system, and the unique telephone number file 503 is a telephone directory file for the application software. Similarly, the call management system B execution file 502 is application software only in the B system, and the unique telephone number file 504 is a phone book file for the application software.

  The unique telephone number file 503 for the call management system A is described in a file format that can be used only by the call management system A. Similarly, the unique telephone number file 504 for the call management system B is described in a file format that can be used only by the call management system B. Therefore, the unique telephone number files 503 and 504 cannot be diverted to different call management systems.

  The common phone number file 510 is a phone book file (phone number list file) described in a common file format, for example, a text file format, which is different from the unique phone number files 503 and 504 for the system A and the system B. is there. The file 510 is a file that does not allow the application software to be used in the mobile radio communication apparatus even if it is used as it is.

  The execution files 501 and 502 for the call management system A and the call management system B are application software for management related to a call, and have the following functions. The execution files 501 and 502 refer to the unique telephone number files 503 and 504 for the call management system A and the call management system A, which are telephone books, respectively, and list telephone number lists registered in the file 503. Display or search display. The execution files 501 and 502 make a dial call to a telephone number when a desired telephone number is selected and designated by a user operation from the displayed telephone numbers. The execution files 501 and 502 can add a phone number that the user desires to add to the phone book or delete an unnecessary phone number. These application software uses a translator to convert the file and update the contents when there is a change in the wireless communication system or when the unique telephone number files 503 and 504 are changed. It has a function to control as much as possible.

  The translator A511 and the translator B512 are software for converting the file format. The translator A511 and translator B512 are used for mutual conversion between the common telephone number file 510, which is a common list file, and the list file specific to the application used in the wireless communication system defined by the modulation / demodulation execution file. It is done.

  That is, the translator A511 converts a list file specific to the application software for the A system into a common telephone number file 510 that is a common list file, and converts the common list file into a list file specific to the application software for the A system. Have Similarly, the translator B 512 converts a list file specific to the application software for the B system into a common telephone number file 510 that is a common list file, and converts the common list file into a list file specific to the application software for the B system. It has a function.

  An operation example of this embodiment will be described. First, it is assumed that the mobile radio communication apparatus operates as a terminal accommodated in the A system. In this state, the modulation / demodulation execution file (processing module) executed by the DSP 410 corresponds to the A system, and the file is stored in the execution file storage unit 411. At this time, the fact that the DSP 410 is executing a modulation / demodulation execution file (processing module) corresponding to the A system is recorded in the RAM 402 by the CPU 401. At this time, the user uses the call management system A dedicated to the A system through the input / output device unit 7. Accordingly, the call management system A execution file 501 stored in the storage device 5 is read into the resource controller 4 and executed by the CPU 401.

  A menu list “Phonebook A” (that is, a telephone number list based on the unique telephone number file 503 for the call management system A), which is a list of telephone numbers of the other party the user frequently calls, is displayed through the input / output device unit 7. Suppose you make the request shown above. At this time, the CPU 401 in the resource controller 4 reads the content of the unique telephone number file 503 for the call management system A read into the resource controller 4 from the storage device 5 and displays it on the display device in the input / output device unit 7. Is done.

  The user can add phone number information to be added to the menu list after making a call with reference to the display of the phone number file on the display device or when a call is received. Is possible. The new telephone number information to be added is first added to the unique telephone number file 503 for the call management system A read in the resource controller 4. Next, when the user ends the use of the call management system A, the CPU 401 executing the call management system A execution file 501 rewrites the unique telephone number file 503 for the call management system A as a storage device. 5 is stored.

  According to the present embodiment, the rewritten telephone number information of the unique telephone number file 503 for the call management system A is managed by being converted into the common telephone number file 510 by the translator A511 stored in the storage device. As a result, the modulation / demodulation execution file executed by the DSP 410 is converted from the file format corresponding to the A system to the file format corresponding to the B system, and the telephone number information is used even when another call management system is used. Is possible.

  Specifically, when the user ends the use of the call management system A (application software as the call management system A execution file 501), or the modulation / demodulation execution file executed by the DSP 410 corresponds to the A system. When the file format is converted to a file format corresponding to the B system and the RAM 402 is rewritten, the CPU 401 executes the translator A511. As a result, the unique telephone number file 503 for the call management system A is converted into a common file format by the translator A511, and the common telephone number file 510 is overwritten with the converted file.

  The flow of this processing will be described below with reference to FIG. As an initial state, it is assumed that the user who possesses the mobile radio communication device is located in the service area of the A system, and the mobile radio communication device functions as a terminal suitable for the A system. Thereafter, when the user moves and the distance between the A system and the base station increases, the received field strength of the mobile radio communication device decreases, and it becomes difficult for the mobile radio communication device to function as a terminal of the A system. At this time, it is assumed that the user is in the service area of the B system, and the mobile radio communication apparatus is in a state where a sufficient received electric field strength can be secured for the base station of the B system.

  The mobile radio communication apparatus uses a radio channel for pilots connected between base stations of the A system and the B system to monitor which radio communication system and communication channel can be secured, thereby It has a mechanism that can be switched. Therefore, the mobile radio communication apparatus can not maintain the line with the A system and can know that the line with the B system can be secured instead. At this time, the modulation / demodulation execution file executed by the DSP 410 is changed by the resource controller 4 to a file corresponding to the B system stored in the execution file storage unit 411, and this change is recorded in the RAM 402 (step S2001). .

  It is checked whether or not the common telephone number file 510 has been overwritten by the translator A 511 according to the call management system A unique telephone number file 503 last updated up to this point (step S2002). If not overwritten, the resource controller 4 executes the translator A512. As a result, the unique telephone number file 503 for the call management system A is converted into the common file format, and the common telephone number file 510 is overwritten with the converted file (step S2003). Thereafter, the process proceeds to step S2004. As a result of the check in step S2002, if overwritten, the process proceeds to step S2004. Step S2004 is not necessarily a necessary process, but in step S2004, the “phone book B” of the call management system B is activated by the user.

  In the next step S2005, the translator B 512 is activated, and the translator B 512 converts the file format of the common phone number file 510 into the file format of the call management system B unique phone number file 504. A telephone number file 504 is generated or overwritten.

  As described above, the unique telephone number files 503 and 504 for the call management system A and the call management system B are described in file formats that can be used only by the corresponding call management systems A and B, respectively. When the contents of the file 503 or 504 are changed, the changed file is once converted into a common file format and stored as a common telephone number file 510. When the radio communication system used by the mobile radio communication apparatus is changed, the common telephone number file 510 is converted into a file so that it can be used under the changed radio communication system. That is, even if the contents of the file 503 or 504 are changed before the wireless communication system used by the mobile wireless communication device is changed, You can use files that reflect changes in.

  Therefore, the user can reflect the call management system A unique telephone number file 503, which has been changed in the A system, to the call management system B unique telephone number file 504 after the transition to the B system. “Phonebook B” becomes available (step S2006). That is, when the menu list “phone book B”, which is a list of frequently used telephone numbers in the call management system B used only in the B system, is displayed, it is updated in the call management system A used in the A system. The contents of the menu list “phone book A” can be used as they are. This eliminates the need for the user to individually manage data for different wireless communication systems, and the latest telephone directory can be used regardless of which wireless communication system is used.

  In the above description, the unique telephone number files 503 and 504 for the call management system A and the call management system B exist on the storage device 5, but these files 503 and 504 are stored in the resource controller as needed. 4 may be a temporary file generated on the memory in the memory 4.

(Twelfth embodiment)
In the mobile radio communication apparatus according to the twelfth embodiment of the present invention shown in FIG. 53, the storage device 5 has web browser A and web browser B execution files 601 and 602, web browser A and web browser B unique URLs. Files 603 and 604, a common URL (Uniform Resource Locators) file 610, a translator A611, and a translator B612 are stored. Executable files 601 and 602 are Web browsing software specific to the A system and the B system used only in the A system and only in the B system, that is, application software for displaying the contents of the data file of the WWW page. is there. Execution files 601 and 602 are read into the resource controller 4 and executed by the controller 4 to realize the functions thereof. The unique URL files 603 and 604 are favorite URL information list files described in a unique file format used by the web browser A and B execution files 601 and 602, respectively. On the other hand, the common URL file 410 is described in a predetermined common file format.

  The translator A411 and the translator B412 are application software for mutually converting the file format between the common URL file 410 and a list file unique to browsing software used in the wireless communication system defined by the modulation / demodulation execution file. . The translator A411 converts the Web browser A specific URL file 603, which is a list file specific to the browsing application software for the A system, into a common list file, and converts the common list file into the Web browser A specific URL file 603. It has the function to do. Similarly, the translator B 412 converts the web browser B unique URL file 604, which is a list file unique to the B system browsing application software, into a common list file, and converts the common list file into the web browser B unique URL file. It has a function of converting to 604. These unique URL files 603 and 604 are both read into the resource controller 4 and executed by the controller 4 to realize their functions.

  As described above, the unique URL file 603 for the web browser A is described in a file format that can be used only by the web browser A, and the unique URL file 604 for the web browser B is described in a file format that can be used only by the web browser B. ing. Therefore, the web browser A cannot designate a web page address unless a URL file described in a dedicated file format is used. Similarly, the Web browser B cannot specify a Web page address unless a URL file described in a dedicated file format is used.

  According to the present embodiment, the URL file is stored in the format of a common list file. When the radio communication system used by the mobile radio communication device is changed, the format of the common list file is changed by the translator to the radio to be changed. Converted for communication systems. The URL information of the Web page can be used on the browser using the converted URL file.

  An operation example of this embodiment will be described. First, it is assumed that the mobile radio communication apparatus operates as a terminal accommodated in the A system. In this state, the modulation / demodulation execution file (processing module) executed by the DSP 410 corresponds to the A system and is stored in the execution file storage unit 411. The signal processing procedure according to the modulation / demodulation execution file is executed by the DSP 410, whereby the function realized by the execution file is realized by the mobile radio communication apparatus.

  On the other hand, the web browser available to the user through the input / output device unit 7 at this time is the web browser A used only in the A system. The web browser A execution file 601 stored in the storage device 5 is read into the controller 4 under the control of the resource controller 4 that recognizes that the mobile wireless communication device is operating under the A system. By being executed by the CPU 401, browsing by the web browser A is enabled. Here, the web browser A is provided with a function for selecting a registered web page address unique to the web browser A by the unique URL file 603 for the web browser A.

  When the user wants to browse a web page that is often browsed on the screen of the web browser A and performs a predetermined operation on the input / output device unit 7, the web browser A uses the unique URL file 603 for the web browser A. Is displayed, and a favorite menu list (favorite Web URL information list) in the web browser A is displayed as a list. The user selects and designates a desired Web page from the displayed favorite menu list on the input / output device unit 7. Then, the signal processing device 3 is controlled by the resource controller 4 and the URL information of the Web page is generated by the DSP 410. The URL information is passed to the wireless transmission / reception device 2 and transmitted to the base station of the A system. The Web site indicated by the URL information on the Internet is accessed from the base station via the Internet provider, and the information on the Web page is read out. The read web page information is transmitted from the base station to the mobile radio communication apparatus along the reverse path.

  In the mobile radio communication apparatus, the received Web page information is sent to the signal processing device 3 via the radio transmission / reception device 2, processed by the DSP 410, and then passed to the resource controller 4. In the resource controller 4, the received web page information is displayed on the screen of the display device in the input / output device unit 7 by the processing of the web browser A by the CPU 401.

  In this way, the user can browse the favorite Web page with a simple operation. It is assumed that the user finds a newly interested web page while browsing the web page. The user can add the URL information of the found Web page to the favorite menu list. In that case, when the user performs a registration operation in the favorite menu list, the resource controller 4 causes the CPU 401 executing the web browser A to read the new URL information that the user wants to register in the web browser A that is read into the resource controller 4. This is added to the unique URL file 603 for use. Thereafter, when the user finishes using the web browser A, the CPU 401 stores the web browser A-specific URL file 603 additionally written in the storage device 5. As a result, the unique URL file 603 for the web browser A stored in the storage device 5 is updated.

  Thus, the updated unique URL file 603 for the web browser A in the storage device 5 has a file format dedicated to the web browser A and cannot be referred to or updated by the web browser B. Therefore, the unique URL file 603 for the web browser A is converted into a file of a common file format and stored in the storage device 5 as the URL common file 610.

  According to this embodiment, the rewritten URL information of the unique URL file 603 for the web browser A is converted into the URL common file 610 format by the translator A 611 stored in the storage device 5 and managed. Thus, even when the modulation / demodulation execution file executed by the DSP 410 is changed from the file corresponding to the A system to the file corresponding to the B system and the web browser B is used, the URL information can be used. Is possible.

  Specifically, when the user ends the use of the web browser A, or the modulation / demodulation execution file executed by the DSP 410 is converted from a file format corresponding to the A system to a file format corresponding to the B system, and the RAM 402 At the time when is rewritten, the CPU 401 executes the translator A611. As a result, the unique URL file 603 for the web browser A is converted into a common file format by the translator A611, and the common URL file 610 is overwritten by the converted file.

  The flow of this processing will be described below with reference to FIG. As an initial state, it is assumed that the user who possesses the mobile radio communication device is located in the service area of the A system, and the mobile radio communication device functions as a terminal suitable for the A system. At this time, the modulation / demodulation execution file executed by the DSP 410 is changed by the resource controller 4 to a file corresponding to the B system stored in the execution file storage unit 411, and this change is recorded in the RAM 402 (step S2011). . Thereafter, when the user moves and the distance between the A system and the base station increases, the received field strength of the mobile radio communication device decreases, and it becomes difficult for the mobile radio communication device to function as a terminal of the A system. At this time, it is assumed that the user is in the service area of the B system, and the mobile radio communication apparatus is in a state where a sufficient received electric field strength can be secured for the base station of the B system. As described above, the mobile radio communication apparatus can no longer maintain the line with the A system, and can know that the line with the B system can be secured instead.

  It is checked whether or not the common URL file 610 has been overwritten by the translator A 611 according to the unique URL file 603 for the web browser A last updated up to this point (step S2012). If not overwritten, the resource controller 4 executes the translator A611. Thereby, the unique URL file 603 for the web browser A is converted into the format of the common URL file 610, and the common URL file 610 is overwritten by the converted file (step S2013). Thereafter, the process proceeds to step S2014. Although step S2014 is not necessarily a necessary process, in step S2014, “favorite” of Web browser B is activated by the user.

  In the next step S2015, the translator B 612 is activated, the translator B 612 converts the file format of the common URL file 610 into the file format of the unique URL file 604 for the web browser B, and the URL file 604 is generated or overwritten.

  As described above, the unique URL files 603 and 604 for the web browser A and the web browser B are described in file formats that can be used only by the corresponding web browser A and web browser B, respectively. Therefore, if the unique URL file described in the dedicated file format is not used in the web browser A, it cannot be used for designating the web page. Similarly, in the web browser B, the unique URL file described in the dedicated file format is used. If you use it, you cannot specify your favorite Web page even if you find it and register it in a file. According to this embodiment, the unique URL file is converted into a common file format URL common file 610 and stored, and the URL common file 610 is further converted into a file format corresponding to the web browser used. It can be used with the web browser. In this way, a list of Web pages based on the browser specific URL file can be used. A user who has migrated from the A system to the B system needs the unique URL file 604 for the web browser B in order to display the favorite menu list in the web browser B used only in the B system. According to the present embodiment, the unique URL file 604 for the web browser B in which the changed contents are reflected by the file format conversion can be obtained. Therefore, when the favorite menu list is displayed, the web browser A used in the A system is displayed. It is possible to reflect the contents of the favorite menu list updated in step S2016 as it is (step S2016). This eliminates the need for the user to individually manage such data in different wireless communication systems, greatly improving convenience.

  In the above description, the unique URL files 603 and 604 for the web browser A and the web browser B exist on the storage device 5. However, these files 603 and 604 are stored in the resource controller 4 as necessary. It may be a temporary file generated on the memory.

(13th Embodiment)
In the mobile radio communication apparatus according to the thirteenth embodiment of the present invention shown in FIG. 55, the mail apparatus A and mail system B executable files 701 and 702, the mail system A and mail system B specific reception are stored in the storage device 5. Mail files 703 and 704, a received mail common file 710, and translators A711 and B712 are stored.

  The execution files 701 and 702 are mail systems unique to the A system and the B system used only in the A system and only in the B system, that is, mailing software used for sending and receiving electronic mail. The execution files 701 and 702 are read by the resource controller 4 and executed by the controller 4 to realize a mailing function.

  Mail files 703 and 704 are received mail files described in a specific file format used in the execution files 701 and 702, respectively. On the other hand, the received mail common file 710 is described in a predetermined common file format.

  Translators A711 and B712 convert the file format between the received mail common file 710 and the specific received mail file having a specific file format in the mail system used in the wireless communication system defined by the modulation / demodulation execution file. File conversion application software. The translator A711 has a function of converting the mail system A specific received mail file 703, which is a received mail file specific to the mailing application software for the A system, into the file format of the received mail common file 710, which is a common file format. Similarly, the translator B 712 has a function of converting the received mail common file 710 into the mail system A specific received mail file 703. These files 703 and 704 are both read into the resource controller 4 and executed by the controller 4 to realize the function.

  As described above, the mail system A specific received mail file 703 is described in a file format dedicated to application software that can be used only by the mail system A, and the mail system B specific received mail file 704 is used only by the mail system B. It is described in a file format dedicated to possible application software.

  The operation of this embodiment will be described. First, it is assumed that the mobile radio communication apparatus operates as a terminal accommodated in the A system. In this state, the modulation / demodulation execution file (processing module) executed by the DSP 410 corresponds to the A system and is stored in the execution file storage unit 411. The signal processing procedure according to the modulation / demodulation execution file is executed by the DSP 410, whereby the function realized by the execution file is realized by the mobile radio communication apparatus.

  On the other hand, the mail system used by the user through the input / output device unit 7 at this time is the mail system A dedicated to the A system. The mail system A execution file 701 stored in the storage device 5 is read into a memory (not shown) in the resource controller 4 and executed by the CPU 401 in the resource controller 4 so that the mail system A can be used. It has become.

  The user issues a request to display on the display through the input / output device unit 7 a menu list “received mail”, which is a list of received mails that have been sent to him / her and stored in the storage device 5. Upon receiving this request, the CPU 401 causes the display device in the input / output device unit 7 to display the contents of the mail system A specific received mail file 703 read from the storage device 5 into the resource controller 4. Therefore, the user can browse the received mail, reply to the received mail, or add a new incoming mail to the list. In this case, the CPU 401 first adds the contents of the new received mail to the mail system A specific received mail file 703 read into a memory (not shown) in the resource controller 4. Thereafter, when the user ends the use of the mail system A, the CPU 401 stores the added mail system A specific received mail file 703 in the storage device 5.

  According to the present embodiment, the file format is converted so that the received mail file that has been used so far can be used even when the mobile radio communication apparatus is shifted to another radio communication system. That is, when the mobile radio communication apparatus uses the A system, the content of the received mail received by the mail system A dedicated to the A system and stored in the mail system A specific received mail file 703 is the mobile radio communication. When the apparatus is transferred to the B system, the mail system B dedicated to the B system can be used. For this reason, when the mail system A specific received mail file 703 is updated, or after the mobile radio communication apparatus has shifted to the B system, the specific received mail file 703 is stored by the translator A 421 stored in the storage device 5. It is converted into the format of the common received mail file 420 and managed by the common received mail file 420.

  Specifically, when the user ends the use of the mail system A, or the modulation / demodulation execution file executed by the DSP 410 is converted from a file corresponding to the A system to a file corresponding to the B system, and the RAM 402 is rewritten. At that time, the CPU 401 executes the translator A712. As a result, the mail system A specific received mail file 703 is converted into a common file format by the translator A 710, and the common received mail file 420 is overwritten by the converted file.

  Hereinafter, the flow of this process will be described with reference to FIG. As an initial state, it is assumed that the user who possesses the mobile radio communication device is located in the service area of the A system, and the mobile radio communication device functions as a terminal suitable for the A system. At this time, the modulation / demodulation execution file executed by the DSP 410 is changed by the resource controller 4 to a file corresponding to the B system stored in the execution file storage unit 411, and this change is recorded in the RAM 402 (step S2021). . Thereafter, when the user moves and the distance between the A system and the base station increases, the received field strength of the mobile radio communication device decreases, and it becomes difficult for the mobile radio communication device to function as a terminal of the A system. At this time, it is assumed that the user is in the service area of the B system, and the mobile radio communication apparatus is in a state where a sufficient received electric field strength can be secured for the base station of the B system. As described above, the mobile radio communication apparatus can no longer maintain the line with the A system, and can know that the line with the B system can be secured instead.

  According to the mail system A specific received mail file 703 last updated up to this point, the translator A 712 checks whether or not the common received mail file 710 has been overwritten (step S2022). At that time, the file format is converted by the translator A 712 from the mail system A specific received mail file 703, and the common received mail file 420 is overwritten according to the converted file (step S2023). Thereafter, processing proceeds to step S2024. Step S2024 is not necessarily a necessary process, but in step S2024, the “inbox” of the mail system B is activated by the user.

  In the next step S2025, the translator B 712 is activated, and the translator B 712 converts the file format of the common received mail file 420 into the format of the mail system B specific received mail file 704, and the received mail file 704 is generated or overwritten. (Step S2025).

  As described above, the mail system B specific received mail file 704 is described in a file format that can be used only by the mail system B. Therefore, when the user displays the menu list “inbox”, which is a list of received mails in the mail system B, by the file conversion, the contents of the menu list “received mail” updated in the mail system A can be reflected as they are. It becomes possible (step S2026). This eliminates the need for the user to individually manage such data for each different wireless communication system, greatly improving convenience.

  In the above description, it is assumed that the mail system A and B specific received mail files 703 and 704 exist on the storage device 5, but these files 703 and 704 are not shown in the resource controller 4 if necessary. It may be a temporary file generated on the memory. In the above description, the received mail is replaced with the transmitted mail, and the same management as described above can be performed on the information of the mail transmitted by the user in the past. The same management as described above is also possible for the mail address information of the partner with whom the user frequently sends and receives mail.
