Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio communication device which can cope with a plurality of radio communication systems.

[0002]

2. Description of the Related Art At present, with the explosion of wireless communication systems, a plurality of wireless communication systems having different standards are mixed. The wireless communication devices are generally prepared for each wireless communication system. Recent mobile wireless communication devices are not only used for traditional voice calls, but also for e-mail,
It is also required to support various application services such as data communication and Web (world wide web) browsing. Therefore, there is an increasing demand for a so-called multi-mode terminal device that can support a plurality of wireless communication systems and various application services with one device.

[0003] As one method for realizing a multimode terminal device, a software defined radio has been proposed. Software-defined radios use programmable devices such as DSPs (digital signal processors)
At least a part of signal processing required for transmission and reception is realized by software processing. The software defined radio can support various wireless communication systems and can support various application services by replacing software. For example, a shift from voice communication to data communication or a wireless communication system using W-CDM
It is possible to perform handoff from the A method to the cdma2000 method. The basic idea of such a software defined radio is described in, for example, Japanese Patent Application Laid-Open No. 9-33157.
No. 9, et al., But the disclosure of how to realize the device in consideration of various situations is insufficient.

[0004] For example, in wireless communication systems, the rate of digital information to be transmitted is being increased, and standards are frequently changed accordingly. Each time this standard is changed, it is necessary to design and develop a software defined radio. A portion of a software defined radio that handles a baseband signal, a so-called modem portion, has a large amount of processing and requires strict specifications such as processing delay. For this reason,
The design of the modem is changed every time the standard of the wireless communication system is changed. The programmable device described above 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 a broadband wireless communication signal.

In order for a software defined radio to respond to various radio communication systems and application services by switching software, resources occupied by the terminal device are occupied a lot. In order to support a new wireless communication system or add an application service function, it is necessary to prepare necessary free resources. Resource management for optimally allocating one resource for a wireless communication system or communication service is also required. In particular, in a mobile radio communication device for mobile communication, the size of resources and the reduction in power consumption are required, so that the amount of resources is limited, so that resource management is important. The resources refer to hardware such as a processor and a memory such as a CPU and a DSP, and the processing capability of the processor.

[0006]

According to the general design concept of a mobile radio communication apparatus, resources are fixedly assigned to a plurality of signal processes. If 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 the resource utilization efficiency is significantly reduced. Resource management found on computers is
It is mainly specialized in the memory area, and no consideration is given to resource management based on hardware space or resource management according to radio quality.

In a software defined radio, for example,
The software module is downloaded through a communication line and stored in a storage device as described in US Pat. No. 3,331,579. When software modules are repeatedly downloaded 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 limited, it is actually necessary to delete unnecessary modules from the modules already stored at the time of downloading. It is necessary to consider updating the module stored in the storage device in accordance with the version upgrade of the 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 for deleting or updating the module. It is desired to realize a mechanism for efficiently managing modules.

[0008] 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 a specific communication partner of the user are stored. A menu display is generally performed. However, in general, a software defined radio capable of supporting a plurality of wireless communication systems cannot use files in these lists if the wireless communication system to be adapted is changed. The 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 unique specifications.

Since the specification of the application service differs for each wireless communication system, a list file of Web pages, telephone numbers, and mail addresses must be prepared for each wireless communication system. The reason is that a file format used in an application service specific to each wireless communication system is a format specific to the application service. Therefore, in the software defined radio, a list file of Web pages, telephone numbers, and e-mail addresses described in a file format compatible with a certain wireless communication system cannot be used for another wireless communication system. When the user of the software defined radio changes the radio communication system to be used, a new list file for application services of the radio communication system must be newly created. Further, there is an inconvenience that the user has to manage the list file for each of a plurality of wireless communication systems that may be used.

[0010] An object of the present invention is to provide a radio communication apparatus for accurately and efficiently managing resources of a signal processing device.

The RF output signal is amplified by a power amplifier 29 through a band-pass filter 28, guided to an antenna 1 by a switch 10, and emitted from the antenna 1 as a radio wave.

The signal processing device 3 in FIG. 1A is, for example, as shown in FIG.
PU) 31, a signal processing unit 32 (SPU), a memory 33, and an input / output interface 34. CP
The U31 executes a process according to a program given in advance, and transmits a predetermined command 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 a trigger from the SPU 32.

The resource controller 4 controls the CPU
The signal processing function of the CPU 31 and the SPU 32 is defined by installing the program in the SPU 31 and the SPU 32. Further, the resource controller 4 determines the sharing of the 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 may be realized by a sequencer on a DSP or a logic circuit.

The SPU 32 is a programmable dedicated processor specializing in signal processing, and specifically uses at least one of a DSP and a PLD. SPU32
Performs signal processing using the memory 33 as a work memory. The SPU 32 outputs the input of the signal to be processed and the output of the processed signal via the external interface 34,
This is performed between the wireless transmitting / receiving device 2 and the system controller 6. Examples of specific processing contents performed by the SPU 32 include “correlation calculation”, “complex calculation”, “maximum value detection”,
Examples include “memory address conversion”, “sequencer”, “high-speed input / output processing”, “cumulative addition”, and “function operation”.

The radio signal processing device according to the present embodiment is a CD
A case where the present invention is applied to an MA (code-division multiple access) system will be specifically described. The SPU 32 in the signal processing device 3 or the SPU 32 and the CP
For both U31, a resource (a despreading circuit resource) composed of, for example, a plurality of logic circuits for performing a despreading process in the CDMA system is prepared. The resources are controlled by the resource controller 4. In a CDMA system, a function of a RAKE receiver operating at finger timing according to multipath transmission and a function of periodically searching for finger timing are required. The search for the finger timing is performed in consideration of the mobile communication environment in which the multipath timing fluctuates. 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 allows the despreading circuit resources used for the RAKE reception to be used for the search processing at a fixed period or at any time according to the communication quality or the like. It is easy. This ensures high quality communication with a smaller circuit scale. In a CDMA receiver that receives a plurality of code channels, despreading circuit resources are allocated to the respective channels by resource management by the resource controller 4 in accordance with connection / disconnection of the code channels. With this configuration, RAKE reception of a plurality of channels can be realized with limited despreading circuit resources, and the circuit scale can be reduced.

As illustrated in FIG. 3B, the SPU3
2 is, for example, a plurality of DSPs 37A and 37B and a PLD 3
8 and are connected by an internal bus 39. The processing of the despreading circuit resources can be performed by both the DSPs 37A and 37B and the PLD 38. In the case of this configuration, the processing capability or the MIPS value of each of the DSPs 37A and 37B and the PLD 38 corresponds to a part of the resources of the signal processing device 3. In the example of the CDMA system, the processing capacity of one despreading circuit is 10 [MIPS].
Is a DSP with a processing power of 100 [MIPS]
Can be treated as a despreading resource similar to ten despreading circuits.

The resource controller 4 allocates the resources of the DSPs 37A and 37B to realize the functions (RAKE reception, multipath search, peripheral cell search, multi-channel reception, etc.) of the mobile radio communication device applied to the CDMA system. The total resources of the signal processing device 3 are allocated so as to apply to all functions required at that time. For example, when a resource equivalent to a total of 15 despreading circuits is 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. 50 [MIPS] equivalent to the capability of the circuit
Of the processing load of the DSP 37A or 37B.
The resource allocation of the signal processing device 3 is not limited to the use in the same wireless communication system. For example, C
DMA system and TDMA (time-division multiple a
ccess) system, TDMA system and FDMA (frequ
ency-division multiple access) system, FDMA
The system and the CDMA system each have common processing elements. For processes that are common among these different wireless communication systems and do not compete in time, resources can be allocated to the signal processing device 3 in the same manner as described above.

As described above, since the function of the mobile radio communication device according to the present embodiment can be reconstructed with a high degree of freedom, the cost required for adding the function and the development period are reduced. The modem unit 3A and the protocol unit 3B shown in FIG. 1B included in the signal processing device 3.
This function is necessary when the function of the mobile radio communication device is reconstructed. 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 similar functions in a plurality of wireless communication systems.

Further, the function of the modem unit 3A and the protocol unit 3B included in the signal processing device 3 shown in FIG. This is useful when used between mobile phones. That is, the mobile wireless communication device can select an optimally usable wireless communication system according to the reception state of radio waves at the destination and the degree of congestion of the wireless channel, and perform communication under the selected system. . This facilitates roaming and handover.

As shown in FIG. 4, a general-purpose processor (CPU) 31 includes a program sequencer (PS) 41 for managing program execution and an arithmetic operation unit (AL).
U) 42. The signal processing unit (SPU) 32 shown in FIG. 3A starts or ends its own processing or performs signal processing according to a programmed sequence, and supplies a trigger signal or an interrupt signal to the CPU 31. . The trigger signal or the interrupt signal supplied to the CPU 31 is detected by the PS 41.
This allows the CPU 31 to change the state of the SPU 32, for example,
Recognizes "end of signal processing" and sets AL based on the recognition.
The processing content of U42 can be changed. By causing the CPU 31 and the SPU 32 to cooperate with each other and to share the processing with each other, it becomes possible to execute complicated calculations at high speed.

As shown in FIG. 5, the SPU 32 has an arithmetic and logic unit (ALU) 51, an instruction memory 52, a data memory 53, and an input / output interface 54. The ALU 51 stores input data from the outside and the memory 33.
In accordance with the data in and the processing instructions and data from the CPU 31, “correlation calculation”, “complex number calculation”, “array conversion”,
Performs advanced signal processing such as “maximum value detection”, “memory address conversion”, “sequencer”, and “high-speed input / output”.
The processing result from the ALU 51 is stored in the data memory 33, the CP
The data is written in the memory and the register in the U 31, the memory 33 and the input / output interface 34. Thus, the CPU 1
The high-level signal processing, which is a heavy burden for processing in step 1, is performed by the SPU 12, which is a dedicated processor, thereby reducing the load 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 constituted by two address decoders 61 and 62 of the memory 60, and a required conversion pattern is written in each address decoder. SPU32
, One of the address decoders 61 and 62 is selected to switch the decoding contents. A register group 63 in the memory 60 is a RAM (random access memory)
Is a memory cell in the memory. The decode contents of a write address decoder and a read address decoder provided in a normal RAM are the same. Therefore,
If a bit array conversion process such as bit interleaving included in the process of the SPU 32 is to be realized by a normal RAM, it is necessary to perform an address calculation for each read.

According to FIG. 6, the address decoders 61 and 6
If 2 is used for the write address decoder and the read address decoder, respectively, such address calculation becomes unnecessary, and conversion processing such as interleave, which requires a large amount of processing, can be performed at high speed. Each of the address decoders 61 and 62 may be a rewritable device such as a RAM, for example, and an address conversion table may be written therein. As a result, since a plurality of conversion patterns can be handled, flexible processing corresponding to various patterns can be realized with a simple configuration.

As shown in FIG. 3A, the CPU 31 and the SPU 32 are connected via a register array 36 in the CPU 31.
It is also possible to exchange data directly with the server. The register array 36 is directly accessed from the SPU 32. That is, the SPU 32 can write its own data output directly to the register array 36, and can also read data directly from the register array 36. CP
U31 can capture the contents of register array 36 and write data to register array 36.

When the register array 36 is used to transfer data between the CPU 31 and the SPU 32, the CPU 3
1 only needs to access the register array 36 regardless of the operation state of the SPU 32 at the time of data transfer. Therefore, the data transfer processing in the CPU 31 can be speeded up, and the processing in the signal processing device 3 can be speeded up.

The operation when the signal processing device 3 shown in FIG. 3A receives the digitized reception IF signal from the radio transmission / reception device 2 at the input / output interface 34 and processes it will be described. Receive signal to CPU
If only the processing is performed, much of the computational power of the CPU is consumed only by input / output processing, and only the remaining power of the CPU can be allocated to other processing. According to the signal processing device 3 shown in FIG. 3A, the SP is used without using the CPU 31 by using the register array 36.
By causing the U32 to execute the input / output processing, the processing capacity of the CPU 31 can be used for processing other than the input / output processing.

The received IF signals captured by the input / output interface 34 are sequentially captured by the SPU 32. If fixed processing is required, the SPU 32 performs required signal processing. The processing result from the SPU 32 is stored in the memory 33.
Alternatively, the data is written to the register array 36. CPU31
Performs necessary processing using data written in the memory 33 or the register array 36.

As described above, the input / output processing and the signal processing are performed by the SPU.
32, 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, high-speed signal processing is realized as a whole of the signal processing device 3. CPU for further load distribution
May be provided, and the processing to be shared by the CPUs 31 in FIG. 3A may be distributed to the respective CPUs.

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

(Second Embodiment) The signal processing device 3 shown in FIG. 7 has 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 a PLD or FPGA (field program).
This is hardware that can redefine a circuit configuration such as a mable 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 enables a combination of various logic circuits to be programmably changed by a switch and realizes a required processing function.

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

The program sequencer 72 receives the resource management program from the resource controller 4 and reads out the program from the memory 74 as appropriate.
In accordance therewith, the circuit configuration description memory 71 and the programmable hardware device 73 are controlled to cause the programmable hardware device 73 to execute signal processing according to the program.

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

The circuit configuration description memory 71 stores, as a program, a circuit configuration description necessary for realizing a desired process in the programmable hardware device 73. More specifically, the circuit configuration description memory 71 stores “four rules operation”, “data transfer”,
In addition to the circuit configuration description for realizing basic processing such as “bit shift” by hardware, for example, “correlation calculation processing”, “complex multiplication processing”, “maximum value detection processing”, “absolute value calculation” And a program showing a circuit configuration description for realizing a process performed by a normal processor in a plurality of steps by hardware, and a circuit configuration description showing 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. You.

In the program area 74A on the memory 74, a number of programs for describing the circuit configuration as described above for the memory 71 are described. A necessary program is read from the block area 74A under the control of the program sequencer 72, and supplied to the circuit configuration description memory 71. Thereby, the circuit configuration of the programmable hardware device 73 is redefined.

As described above, 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 requiring several tens to several hundred steps at high speed within several cycles, and can flexibly cope with various definitions of signal processing functions.

(Third Embodiment) The signal processing device 3 shown in FIG. 8 has a CPU 75 in addition to the components shown in 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 in FIG. However, here, the program sequencer 72 further selects a device in accordance with the processing content so that the programmable hardware device 73 performs predetermined complicated signal processing and the CPU 75 performs normal signal processing. It has a function and a function of controlling the programmable hardware device 73 and the CPU 75 to operate simultaneously to execute parallel processing.

In particular, in the signal processing of the modem unit 3A of the signal processing device 3 shown in FIG. 1B, the resource management program from the resource controller 4 is executed by the program sequencer 72 so that the signal processing device 3 Of the processing to be performed by the programmable hardware device 73 and the CPU 75 is determined according to the signal processing function to be provided by the CPU. 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 given an instruction from the program sequencer 72 to execute the processing to be shared by the CPU 75.

Under the above-described control by the program sequencer 72, the signal processing complicated and burdensome for the CPU 75 is performed by the programmable hardware device 73, which is a processor dedicated to signal processing, and the other processing is performed by the CPU 75. .

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

32.

According to the present embodiment, even in an environment where the resources of the signal processing device 3 owned by the mobile radio communication apparatus and the resource usage are different from each other, the mobile radio communication apparatus can respond to the ever-changing resource usage. Thus, a new signal processing function can be efficiently added. In other words, by adding a new signal processing function using information on the status of resources that are already being used by itself, optimal allocation of resources becomes possible.

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

In this example, the configuration description information providing device 140 transmits the configuration description information to the mobile radio communication device 1 by wireless communication.
In order to provide the configuration information, an antenna 141, a wireless transmission / reception device 142, and a buffer 143 for storing configuration description information are provided. Communication between the mobile wireless communication device 10 and the configuration description information providing device 140 may be wired. For example, in a service center that updates a function of the mobile wireless communication device 10, the configuration description information providing device 140 may be used as a device that updates the function.

As shown in FIG. 1, the mobile radio communication device 10 has an antenna 1, a radio transmission / reception device 2, a signal processing device 3, a resource controller 4, a storage device 5, a system controller 6, and an input / output device unit 7. The resource controller 4 includes the resource management table 130 and the resource manager 13 as shown in FIG.
1, a resource update system 132, a buffer 133, and a resource monitor system 34 for monitoring the use status of resources of the signal processing device 3.

In the configuration description information providing device 140,

The read configuration description information is transmitted to the wireless transmitting / receiving device 14.
2 to the mobile radio communication device 10.
The configuration description information transmitted to the mobile wireless communication device 10 includes:
Received by the wireless transmitting / receiving device 2. The resource controller 4 grasps a 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 amount of the surplus resources that the signal processing device 3 is not using is grasped based on the usage status of the resources monitored by the resource monitoring system 134. The resource controller 4 optimally allocates resources to signal processing functions to be additionally defined as resources of the signal processing device 3 according to the required resource amount and the surplus resource amount.

FIG. 17 shows another configuration of a radio communication system including mobile radio communication apparatus 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 usage status of the resources of the signal processing device 3 that is monitored by the resource monitor system 134 when a new signal processing function is to be additionally defined for the resources of the signal processing device 3 in the mobile radio communication device 10. Is transmitted from the wireless transmitting / receiving device 2 to the configuration description information providing apparatus 140 via the antenna 1.

In the configuration description information providing device 140,
The configuration description information indicating the signal processing function to be newly defined for 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 to the resources 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 resource monitored by the resource monitoring system 134. The resource controller 144 calculates the optimum resource allocation for the signal processing function additionally defined as the resource of the signal processing device 3 according to the required resource amount and the surplus resource amount, and outputs the resource allocation instruction information.
This resource allocation instruction information is transmitted to the wireless transmitting / receiving device 14.
2, the mobile radio communication device 1 via the antenna 141
Sent to 0.

The resource allocation information transmitted to mobile radio communication apparatus 10 is received by radio transmitting / receiving device 2 via antenna 1 and passed to resource controller 4. The resource controller 4 performs an optimal resource allocation for a signal processing function to be additionally defined as a 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 device 140. That is, the calculation required to add a new signal processing function to the resources of the signal processing device 3 in the mobile radio communication device 10 is as follows:
This is performed outside the mobile radio communication device 10. As a result, the amount of calculation performed by the resource controller 4 of the mobile wireless communication device 10 is reduced, so that the mobile wireless communication device 1
0 can be reduced. That is, the processing required for resource allocation of the signal processing device 3 of the terminal is assisted by the base station, so that the processing load on the terminal required for resource allocation is reduced.

The operation of the present embodiment will be described with reference to FIGS. Referring to FIG. 18, first, mobile radio communication apparatus 10 receives the configuration description information transmitted from configuration description information providing apparatus 140 (step S10).
1). In the mobile radio communication device 10, the resource controller 4 obtains the required resource amount required for additionally defining the signal processing function for the signal processing device 3 using the received configuration description information (step S102). The required resource amount is compared with the resource amount (initial resource amount) of the signal processing device 3 when the mobile radio communication device 10 is shipped (step S103). If the required resource amount is larger than the initial resource amount, the configuration description information providing apparatus 140 is notified that the 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 use 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 is compared with the required resource amount, and it is determined whether or not a new signal processing function can be additionally defined in the signal processing device 3 (step S106). If additional definition is possible, a new signal processing function is defined in the resources of the signal processing device 3 by the resource update system 132 (step S1).
07). In step S107, the allocation of the resource of the signal processing function already defined in the signal processing device 3 is changed as necessary. If it is not possible to add a new signal processing function, it notifies the configuration description information providing device 140 of that (step S104). The process of step S103 may be omitted.

Referring to FIG. 19, the processing from steps S201 to S204 is performed at step SS201 in FIG.
This is the same as the processing from 101 to S104. In step S205, 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 the signal processing device 3 can be additionally defined with a new signal processing function. If additional definition is possible, the resource update system 13
2, a new signal processing function is added to the signal processing device 3
(Step S207), and updates the resource management table 130 accordingly (step S207).
208).

According to FIG. 20, steps S301 to S301
Steps 305 and S307 and steps S308 are the same as steps SS201 to S204 and 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 generally differs for each mobile radio communication device. Accordingly, the configurations and sizes of the non-redefinable area 3A and the redefinable area 3B illustrated in FIG. 11 also differ for each mobile wireless communication device. Therefore, in order to efficiently allocate resources to the signal processing functions of the signal processing device 3, the details of the resources of the signal processing device 3, for example, the number of CRC addition 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 a configuration description information providing apparatus 140 which 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 a resource of the signal processing device 3 in the communication mobile radio communication apparatus 10, the resource controller 144 uses the signal processing device 3. You need to be able to understand the details of the resources.

Hereinafter, the configuration description information providing device 140 is provided in the base station, and the mobile radio communication device 10 is a terminal.
7 as an example, the mobile radio communication device 1
A method for ascertaining details of resources of the signal processing device 3 within 0 (hereinafter referred to as terminal resources) in the base station will be described.

As shown in FIG. 21, the layer configuration in a normal base station (L1 / L2: layer 1 / layer 2)
Has a data link control (DLC) and a physical layer (PHY). DLC stands for Media Access Control (MAC), Error Control Block (E
C) and a radio resource controller (RRC). In the base station, the error control block (EC) receives the data transmitted from the upper layer, and performs signal processing to withstand the error generated in the wireless transmission / reception device. The signal output from the error control block (EC) is used for media access control (M
AC). The signal output from the MAC is sent to the physical layer (PHY). In the 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 signal flow.

FIG. 22 shows a layer configuration in a base station of the radio communication system according to the present embodiment. 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). TRC has its own RRC (Radio Resource Control)
Communication with l), thereby obtaining the machine number or model information of the terminal. That is, the TRC monitors the communication between the terminal and the base station to obtain the machine number or model information of the terminal.

One of the methods for grasping the resources owned by the terminal from the machine number or the terminal model information is as follows.
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. In the resource list, as illustrated in FIG. 24, a function block name and the number of each function block are described, and further, special notes such as that simultaneous use is impossible are described.
As described above, resources are divided into non-redefinable areas and redefinable areas.

Using the information of the resource list as exemplified in FIG. 24, the TRC grasps the required resource amount for defining the desired signal processing function in the terminal resource, and obtains the optimum resource allocation by calculation. Outputs resource allocation instruction 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 a base station (B) according to the present embodiment.
S) and the layer configuration of the terminal (MT). Base station BS
And a resource controller (RC) in the terminal MT. The TRC has a resource list for each terminal. Terminal resources are different for each terminal. RC
Has a resource management table indicating the usage status of terminal resources. The ratio between the non-redefinable area and the redefinable area of the terminal resource differs for each terminal. The usage status of the terminal resources is monitored by the resource monitoring system.

The TRC provided at the base station BS is a terminal M
Communication is performed with the RC provided in T, and information on the usage status of the terminal resources is obtained from the terminal. The TRC, for example, as shown in FIG.
6 is transmitted to the RRC.
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 resources to the base station. R of terminal MT
Upon receiving this request, C updates the terminal resource usage 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 recognizes the type and quantity of resources owned by the terminal MT based on the list. 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. RRC receiving the resource usage table
Transmits a message as shown in FIG. 28 to the TRC provided in the base station.

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

In terminals capable of changing the signal processing function, the amount of resource used changes successively. That is, there may be a case where some of the functions once set in the terminal become unnecessary. Therefore, by updating the resource management table at the time of adding a function, it is possible to perform resource management based on the latest information.

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

(Sixth Embodiment) FIG. 29 shows a mobile radio communication device according to a sixth embodiment of the present invention. This mobile radio communication device 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. 29, the system controller 6 and the input / output device unit 7 shown in FIG. 1 are omitted.

The signal processing device 3 is constituted by a processor that performs signal processing by 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 from which an execution program is read, and includes a module group constituting a program for performing signal processing in the storage area. The signal processing is executed by reading. The module here is a compiled executable file, and each signal processing function is a software module.

The storage device 5 stores programs and data files. In particular, as the program, a module group assumed to have specifications in the signal processing device 3 is stored. Thereby, the mobile radio communication device is in 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 has 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 includes a data transmission module 221, an equalizer module 222, a Viterbi decoder module 223, and a CRC module 2
24 are stored.

The resource controller 4 includes a source management table 200, a resource manager 201, a resource rewriting processor 202, and a download buffer 20.
3 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 the resources are replaced, (b) whether to replace the resources, and (c) the timing for the replacement. The resource rewriting processor 202 rewrites the module of 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 embodiment described above.
The specific operation is as follows. It is assumed that the wireless transmission path between the mobile wireless communication device and a base station (not shown) is deteriorated due to shadowing, that is, the mobile wireless communication device is behind a shadow, and the desired communication quality is not satisfied. The communication quality is detected by, for example, an electric field measuring function of the wireless transmitting / receiving device 2.

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

As shown in FIG. 30, the storage device 5
If there is an equalizer module 222 therein, the resource controller 4 reads it into the signal processing device 3 as an execution file of the processor which 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.

Signal processing device 3 in mobile radio communication device
If the required module is not stored in the storage device 5, a download request is issued to, for example, a base station having an area where the mobile radio communication device is currently located as a service area. 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 wireless communication device that issued the download request.

The necessary signal processing functions are defined in the signal processing device 3 by exchanging the programs stored in the storage area of the processor as the signal processing device 3 as described above. As a program, necessary modules are imported only when necessary. As a result, it is possible to suppress the waste of resources due to the resident modules that are normally unnecessary in the storage area of the processor, that is, the unnecessary occupation of the memory resources. 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 device according to the present embodiment will be described. First, a case in which the communication type is switched, such as switching from a state in which the mobile wireless communication apparatus is used for voice communication to a state in which data communication such as Web browsing is used, will be described.

When the type of communication is to be switched from, for example, voice communication to data communication, a module for voice communication, for example, a voice CODEC module is not required. Instead, a module with a new TCP / IP is required. Become. The resource manager 201 checks whether or not a 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. Unnecessary voice CO
A voice call module such as a DEC module is cleared from the storage area of the processor.

[0103] The resource manager 201
If it is not in the TCP / IP module, it is obtained by downloading as described above. Obtained TCP / IP
After the module is stored in the storage device 5, it is written to the resource management table 200. Resource Manager 2
In step 01, the resource management table 200 checks again whether a TCP / IP module exists in the storage device 5. If a TCP / IP module exists in the storage device 5, it is read into the storage area of the processor as an execution file. This enables data communication thereafter.

This operation will be described with reference to FIGS. 31 and 32. As shown in FIG. 31, in the storage area of the signal processing device 3, the audio transmission module 211 is stored as in FIG.
And the voice receiving module 212 are read. 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 21
0 uses the voice transmission module 211 and the voice reception module 212 to perform signal processing for voice communication. In this state, it is assumed that the user of the mobile wireless communication apparatus next operates the input / output device unit 7 shown in FIG. 1 to give an instruction to shift to data communication. Upon receiving this instruction, the resource controller 4 issues a resource update request (step S402). Thereby, the resource controller 4
Resource manager 201 of the resource management table 2
With reference to 00, it is checked whether or not the data communication module exists 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 so, the DSP 210 is notified of rewriting start (step S404).
As a result, the DSP 210 stops executing the module currently in the storage area.

Next, the resource controller 4 deletes the voice transmitting module and the voice receiving module present in the storage area of the DSP 210 using the rewriting processor 202, reads the data transmitting module and the data receiving module from the storage device 5, and reads 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 the 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).

Thus, the resource controller 4
The storage area of the DSP 210 (DSP 210
Module in the memory resource). As a result, the signal processing function of the DSP 210 is changed from a voice communication function to a data communication function.
The signal processing function can be replaced by utilizing the limited storage area of the data processing apparatus. Therefore, occupation of memory resources by unnecessary modules can be suppressed.

According to the example of FIG. 33, the signal processing device 3
Instead of a DSP, a programmable hardware device that can be rewritten programmatically, for example, a PLD 230
Is used. The PLD 230 includes a module group 231
(For example, modules A, B, C, and D), and the storage device 5 has a module group 240 (for example, modules A,
B, C, D, E, F,...) Are stored. The module mentioned here is a circuit configuration program (circuit configuration description)
Module, for example, as shown in a PLD layout diagram.

The operation will be described with reference to FIG.
The LD 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. 1 to give an instruction to shift to data communication. The resource controller 4
In response to this instruction, a resource update request is issued (step S
502). It is assumed that the modules B, C, and D are modules for constructing a circuit configuration related to signal processing required for both voice communication and data communication.

In the data communication, the modules B, C, D,
Since E is required in advance, the resource controller 4 knows that the module A needs to be replaced with the module E by checking the current module configuration in the PLD 230. 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 is a rewriting processor 202
, The module group 2 held in the PLD 230
An instruction to rewrite module A in module 31 to module E is given. In response to the rewrite instruction, the rewrite processor 202 sends a rewrite start notification of the module to the PLD2.
30 is performed (step S505). This allows
The PLD 230 stops the execution of the processing in the circuit configuration by the currently held module. Next, the rewriting 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).

In this manner, the rewriting processor 202
Is completed, the resource controller 4 notifies the PLD 230 of the completion of rewriting (step S507). Upon receiving the rewriting completion notification, the PLD 230 constructs a circuit configuration using the newly held module group 231 (modules B, C, D, and 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).
In response to this request, the module E is downloaded and temporarily stored in the download buffer 203. After that, in step S505, the PLD 230 is notified of the start of rewriting (step S505). This allows
In step S506, the module E held in the download buffer 203 is read by the rewriting processor 202 and written to the PLD 230.

As described above, the downloaded module E can be written to the PLD 230 during the download or immediately after the download is completed, and it is possible to shift from the voice call to the data communication in a short time.
The module obtained by the download is not only temporarily stored in the download buffer 203, but is also stored in the storage device 5 as needed, and used for subsequent use.

(Seventh Embodiment) In the sixth embodiment,
When the signal processing function of the signal processing device 3 is switched, a module that is unnecessary for realizing a new signal processing function among a plurality of necessary modules is replaced. A module group in which modules required for each application are set may be prepared, and when switching the signal processing function, the modules may be replaced in units of module group.
This makes it possible to switch the signal processing function of the signal processing device 3 at high speed.

FIG. 35 shows a mobile radio communication apparatus according to the seventh embodiment for performing such replacement in units of module groups. This mobile radio communication device is adaptable to a plurality of different radio communication systems. Therefore, 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, 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 using the radio communication system X, in this state, it is necessary to perform communication with the base station using the radio communication system Y in order to perform a handover, for example. Assume that it has occurred. In this case, the resource manager 201 determines that it is necessary for the mobile radio communication device to perform communication with the radio communication system Y, and controls the order of exchanging resources, the decision whether or not to exchange resources, and the timing of exchanging resources. The resource manager 202 releases an unused module in the system X and issues an instruction to the rewriting processor 202 to incorporate a module for the system Y. Upon receiving this instruction, the rewriting processor 202 performs a module rewriting process on the DSP 210 from the storage device 5.

Here, since the radio communication system X is still in use, it is necessary to leave the used module among the modules for the system X written in the storage area of the DSP 210. Therefore, a module that is not used is checked, the module is released from the storage area of the DSP 210, and the module for the system Y is incorporated in the storage area generated as a surplus resource. Thereby, the mobile radio communication device can perform communication in both the radio communication systems X and Y.

Referring to FIG. 36, modules X1, X2, X
The operation in the case where the module X1 is opened and the module Y1 is read in order to perform communication under the system Y from the state where signal processing is performed using X3 and X4 will be described.

First, in step S601, the DSP 2
Modules X1, X2, X3, and X4 for performing communication under the system X are written in the storage area 10 and the DSP 210 stores the modules X1, X2, X3, and X4.
Is used for signal processing. In this state, for example, when a handover occurs, the resource controller 4 issues a module update request (step S602). The resource manager 201 receives the module update request, refers to the resource management table 200, and
It is checked whether there is a module group for the communication system Y, and the configuration of the module group for the communication system X is checked (step S603).

The resource manager 201 determines the modules required for communication in the wireless communication system Y, determines which one of the modules for the wireless communication system X is to be replaced, and determines the order in which the resources are replaced. . As a result, the resource manager 201 does not need the module X1, needs the module Y1,
After deleting X1, it is determined that Y1 should be written. Further, the resource manager 201 gives an instruction to the rewriting processor 202 to rewrite the module X1 in the module group 213 held in the DSP 210 to the module Y1. Rewrite processor 202
Receives this instruction and notifies the DSP 210 of the start of module rewriting (step S604). As a result, the DSP 210 stops the execution of the process by the currently held module.

Next, the rewriting processor 202
The module X1 of the module group 213 held in P210 is discarded, and the module Y1 is read from the storage device 5 and replaced with the module X1 instead (step S605). When the rewriting process is completed, the resource controller 4 notifies the DSP 210 of the rewriting completion (step S606). DSP210
Receives this notification, and holds the module group 21
Signal processing for data communication is performed using module 3 (modules X2, X3, X4, Y1) (step S607).

Thus, the resource controller 4
By exchanging the modules in the DSP 210 under the management of, the module storage area of the DSP 210 (memory resource with a finite capacity) is effectively used, and the communication that has been performed only under the communication system X until now is communicated. X and Y can be performed. Thereby, handover can be easily realized.

Another operation example of this embodiment will be described with reference to FIG. Assume that the mobile radio communication device is communicating under radio communication system U. When the mobile radio communication apparatus performs a handover to perform communication under another radio communication system V at a cell (ie, service area) boundary, the resources of the DSP 210 which 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. This enables soft handover between different wireless communication systems.

More specifically, the module read by the DSP 210 is gradually occupied by the system V from the state of being occupied by the system U. As for the module for the system V, if it is stored in the storage device 5 in advance, it is used; otherwise, it is obtained by downloading.

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

[0127] The resource manager 201
0, the resource management table 200 storing the storage locations of the modules that can be executed is determined by referring to the resource replacement table, the determination of whether or not to replace the resources, the timing of the replacement, and the like. The rewriting processor 202 and the DSP 210 Then, the start of rewriting is notified (steps S703-S704). This gives D
In SP210, the module group 213 currently held
Cancel the execution of the process in. At this point, the modules 213 that have already been written to the DSP 210 include all the modules U1, U2, and U for performing signal processing for communication under the system U, as shown in step S705.
3, U4, and does not include a module for performing signal processing for communication in the system V.

Therefore, the rewriting processor 202 controls the DSP 210 under the control of the resource manager 202.
First, the storage area of the module U1 is released in order to gradually rewrite the module group 213 written in the module U1.
Next, the rewrite processor 202 writes the module V1 read from the storage device 5 in the opened area (Step S706). Next, the rewriting processor 20
2 releases the storage area of the module U2, and writes the module V2 read from the storage device 5 into the released area (step S707). Similarly, next, the rewrite processor 202 releases the storage area of the module U3,
The module V3 read from the storage device 5 is written in the opened 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 into the released area (Step S709).

As described above, under the control of the resource manager 201, the DSP
Rewriting of the module in the storage area 210 is performed gradually. If all necessary information has been rewritten, the resource manager 201 notifies the DSP 210 of the end of rewriting (step S710). DSP2 that received this notification
10 performs data communication processing using the currently held module group 213 (modules V1, V2, V3, and V4) (step S711).

Thus, the resource controller 4
213 in the DSP 210 under the management of
Are gradually replaced according to the required signal processing function. This enables soft handover between different wireless communication systems while effectively utilizing the module storage area (memory resource having a finite capacity) of the DSP 210, that is, suppressing occupation of resources by unnecessary modules.

(Eighth Embodiment) As shown in FIG. 38, in a mobile radio communication apparatus according to a seventh embodiment of the present invention, a programmable hardware device, for example, a PLD
230, a common hardware resource 232 is prepared for the signal processing device 3 using the same. 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.

While the mobile radio communication device 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 a module for a wireless communication system to be newly monitored is incorporated. The procedure of 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 commonly used under the wireless communication system used by the mobile wireless communication device for communication and another wireless communication system to be monitored. By using the common hardware device 232, the processing load of the resources of the PLD 230 is reduced.

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

(Ninth Embodiment) In a mobile radio communication apparatus according to a ninth embodiment of the present invention shown in FIG. 39, an execution file 214 common to a plurality of radio communication systems is stored in the signal processing device 3. ing. As described in the eighth embodiment, a case is considered in which the mobile wireless communication device monitors another wireless communication system while communicating under a certain wireless communication system. In such a case, similar to the procedure described in the seventh embodiment, the DSP 2
A part of the module group 213 read into the module 10 is released, and a part of a module for a wireless communication system to be newly monitored is incorporated.

The fixed common execution file 214 is used in common for each wireless communication system. Therefore, the execution file 214 is commonly used under the wireless communication system used for communication by the mobile wireless communication device and another wireless communication system to be monitored. By using the common execution file 214, the processing load of the resources 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. 40 (a), the resource controller 4 includes the module management table 300, the module manager 301, It has a 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 (hereinafter, referred to as a processing module) indicating a signal processing procedure of the DSP 310 is stored. The signal processing device 3 may be realized by a programmable hardware device such as a PLA or an FPGA in place of the DSP. Stored as a module.

The module management table 300 stores the storage status of the processing modules used in the mobile radio communication device,
The allocation state of the processing module to the resources of the signal processing device 3 and the use history of the processing module are recorded, updated, and used by the resource controller 4 itself. As shown in FIG. 40B, the module management table 300 has at least a module storage state table 3001, a module allocation state table 3002, and a module use history table 3003.

The storage state of a processing module is managed by a module storage state table 3001. The allocation status of the processing modules to the resources is managed by a module allocation status table 3002. Information on the use history of the processing module including the allocation state information of the module to the resource and the storage state information is managed by the module use history table 3003. The module manager 301 records the use history information of the processing module in the module management table 300, and saves, deletes, and updates the processing module using the module management table 300.

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. The module rewriting processor 302 assigns a processing module from the storage device 5 to the signal processing device 3 and notifies the start / end of rewriting of the processing module according to an instruction from the module manager 301. The signal processing device 3 to which the processing module is assigned by the module rewriting processor 302 fetches the assigned processing module from the storage device 5 and executes the signal processing procedure described in the processing module.

FIG. 40A shows a display device 321 and an input device 322 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 radio communication device via the interface 8 are prepared as required.

Next, the operation of the mobile radio communication apparatus according to the present embodiment will be described. The signal processing device 3 is shown in FIG.
As shown in FIG. 0 (a), it is assumed that the DSP 310 and the program memory 311 are provided. Now, at a point where a user of a mobile wireless communication device is located, two types of wireless communication systems (system A and system B) are respectively providing services, and these wireless communication systems are used by the mobile wireless communication device. Suppose you were in a possible situation.

In the mobile radio communication device, it is assumed that the user has designated by using a key of the input device 321 to use a desired radio communication system, for example, the A system. 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 transmitting / receiving device 2 to the base station via a control channel prepared as a channel common to each wireless communication system, for example. The base station reads a processing module indicated by the received download request from a server in the base station or a server provided on a network to which the base station is connected, and transmits the read processing module to the mobile radio communication device that has issued the request.

[0145] 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 thus received, that is, downloaded, is temporarily stored in the download buffer 303 by the resource controller 4 and then transferred to the storage device 5 and stored.

Next, in the resource controller 4, a processing module allocation request is issued from the module manager 301 to the module rewriting processor 302. The module rewriting processor 302 performs control to read out necessary processing modules from the storage device 5 in accordance with the processing module assignment request and write the necessary processing modules 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,
The signal processing determined by the processing module is realized.
Therefore, the user of the mobile wireless communication device can use a new function of the processing module written in the program memory 311.

The module manager 301 reads out the necessary processing modules from the storage device 5 and writes the necessary processing modules into the program memory 311 to effectively utilize the finite memory capacity of the program memory 311 as follows. By referring to the contents of the module use history table 3003 recorded in the module management table 300, the control unit 205 controls the replacement order of processing modules in the program memory 311, determines whether or not to replace the processing modules, and determines the replacement timing.

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

The processing module assignment request is given to the module rewriting processor 302, and the processor 302 writes necessary processing modules to the program memory 311. In the signal processing device 3,
The processing module written in the program memory 311 is executed by the DSP 310. Thus, the function realized by the processing module written in the program memory 311 is realized by the mobile wireless communication device. That is, the program memory 311 is stored in the mobile wireless communication device.
A new function by the newly written processing module is added.

Program memory 3 of signal processing device 3
In 11, a plurality of processing modules can be written. In the signal processing device 3, the program memory 311
DSP3 with multiple processing modules coexisting
10 executes an arbitrary processing module. The capacity of the program memory 311 and the capacity of the storage device 5 are both finite. Since the order in which the processing modules are replaced in the signal processing device 3, the determination as to whether or not to replace the processing modules, and the timing of the replacement are controlled by the module manager 301, the situation where the capacity of the program memory 311 is insufficient can be suppressed.

If the processing module is stored in the storage device 5 every time the mobile radio communication device downloads a new processing module, the free storage area of the storage device 5 may eventually become insufficient. When the free storage area is exhausted in the storage device 5, it is necessary to secure another free storage area 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 wireless communication device, that is, the processing module that has a low probability of being used next time by the mobile wireless communication device. For this reason, the use frequency of the processing module 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 that is used least frequently on the module usage history table 3003. As a result, an empty storage area of the storage device 5 is secured, and the new downloaded processing module is stored in the storage device 5.

FIG. 41A shows a module use history table 3003 in the module management table 300.
A list of items described in is shown. The items of the module use history include a module name, a module size, a use frequency, a storage state, and an allocation state. The module name is the name of the processing module. The module size is the 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 wireless communication device. The storage state is information indicating a state in which the processing module is stored in the storage area. Specifically, the storage state is an address of the program memory 311 if the processing module is stored, and if the processing module is not stored, NO. The allocation state is information indicating whether the processing module is allocated to the program memory 311 or not.
N, OFF if not assigned.

Processing modules whose resource allocation state is OFF are stored in the storage device 5 but are not allocated to the program memory 311. The processing module to be deleted is selected from the processing modules whose resource allocation status is OFF. When all the processing modules are allocated to the program memory 311,
The processing module to be deleted is the program memory 3
11 is released and then deleted.

FIG. 41B shows a specific example of the contents of the module use history table 3003. In this example, the module names include QPSK modulation, correlator, convolutional coding, PN coding, and Walsh coding. Module size is 10200Byte, 15300Byte, 1290 respectively
0Byte, 25000Byte, 18000Byte, and usage frequency is 320 times, 230 times, 202 times, 23 times, 98 times, respectively, and the storage locations are 0x100, 0x400, 0x5000, 0x3000, NO
(However, 0x indicates hexadecimal notation), which indicates that the assignment states are ON, ON, OFF, OFF, and OFF, respectively.

Referring to FIG. 42, a processing procedure for deleting unnecessary processing modules in storage device 5 using the usage frequency information recorded in module usage history table 3003 shown in FIG. 41 (b) will be described. explain. This processing procedure is executed by the module manager 301. When deletion of a module is started (step S701), the use frequency is referenced from the items recorded in the module use history table 3003 (step S702).
By this reference, among the processing modules whose assignment status is OFF, the processing module with the least frequency of use is searched.
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 use 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 use history table 300 shown in FIG. 41B, Walsh coding among convolutional coding, PN coding, and Walsh coding which are processing modules whose allocation state is OFF. Is the least frequently used. Therefore, the processing module for this Walsh coding is deleted. The history information of the Walsh code processing module is deleted from the module usage history table 3003. Thus, the storage device 5
When the necessary capacity is secured, the deletion of the processing module ends (step S706). As a result, FIG.
Module usage history table 300 shown in (b)
The content of No. 3 is updated as shown in FIG.

By deleting the processing modules by the module manager 301 in such a procedure, the processing modules that are frequently used, that is, the processing modules that are likely to be used next, are stored in the storage device 5. . Accordingly, the download processing of the processing module that is likely to be used is not performed unnecessarily, so that the processing load on the mobile wireless communication device is reduced.

Next, the case where the module use history tables shown in FIGS. 43 (a) to 43 (c) are used will be described. As shown in FIG. 43 (a), a list of items described in the module use history table 3003 is shown in FIG. Is the same as The latest use date is a latest time stamp when the processing module read from the storage device 5 is written into the program memory 311. As shown in FIG. 43B, an example of the contents of the module use history table 3003 indicates that the use update date is 2005/04/14, 2005/12/21, 2003.
It is the same as FIG. 41A except that / 05/04, 2005/02/03 and 2005/08/14 are entered.

Referring to FIG. 44, processing for deleting unnecessary processing modules in storage device 5 by using the latest use date and time information recorded in module use history table 3003 shown in FIG. 43 (b). The procedure will be described. This processing procedure is executed by the module manager 301. When the module deletion starts (step S8)
01), the latest use date and time among the items recorded in the module use history table 3003 is referred to (step S802). By this reference, the allocation state is changed to “OF”.
Among the processing modules of F ", a processing module with the oldest latest use date and time is searched, and an instruction to delete the processing module from the storage device 5 is given to the resource controller 4. The resource controller 4 assigns the processing module to which the deletion is instructed. Delete from the storage device 5 (step S8)
03). The module manager 301 deletes the history information of the deleted processing module from the module use 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 in the storage device 5 has been secured.

For example, according to the example of the contents of the module use history table 300 shown in FIG. 43 (b), among the convolutional coding, PN coding and Walsh coding which are processing modules whose allocation state is OFF, The latest use date of is the oldest. Therefore, the convolutional coding processing module is deleted from the storage device 5, and the history information of the convolutional coding processing module is deleted from the module use history table 3003. When the necessary capacity is secured in the storage device 5, the deletion of the processing module ends (step S806). As a result, the module use history table 3 shown in FIG.
The contents of 003 are updated as shown in FIG.

By deleting the processing module by the module manager 301 in such a procedure, the processing module having 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. You. Accordingly, the download processing of the processing module that is likely to be used is not performed unnecessarily, so that the processing load on the mobile wireless communication device is reduced.
Further, when the mobile wireless communication device is used by a user whose usage situation changes frequently, it is possible to add and delete a processing module without waste according to the usage situation.

Next, the case where the module use history tables shown in FIGS. 45 (a) to 45 (c) are used will be described. As shown in FIG. 45 (a), a list of items described in the module use history table 3003 is shown in FIG. And FIG. 43
Same as (a).

Referring to FIG. 46, a processing procedure for deleting unnecessary processing modules in storage device 5 using module size information recorded in module usage history table 3003 shown in FIG. Will be described. This processing procedure is executed by the module manager 301. When deletion of a module starts (step S901), a module use history table 3003
The module size is referred to among the items recorded in (1) (step S902). By this reference, a processing module having the largest module size is searched for among 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 use history table 3003 (Step S904). The operations in steps S902 to S904 are performed in step S905.
Is repeated until it is determined that the necessary free space has been secured.

For example, according to the example of the contents of the module use history table 300 shown in FIG. 45B, Walsh coding among convolutional coding, PN coding, and Walsh coding which are processing modules whose allocation state is OFF. Has the largest module size. Accordingly, the Walsh coding processing module is deleted from the storage device 5 and the history information of the Walsh coding processing module is deleted from the module use history table 3003. When the necessary capacity of the storage device 5 is secured in this way,
The deletion of the processing module ends (step S90).
6). As a result, the contents of the module use history table 3003 shown in FIG. 45 (b) are updated as shown in FIG. 45 (c).

By deleting the processing modules by the module manager 301 in such a procedure, the 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, the possibility that an area larger than the required storage area size on the storage device 5 is secured by one deletion operation increases. As a result, the number of operations for deleting the processing module is minimized, and the processing load required for the deletion is reduced.

Next, the module use history table 300
An example in which a function of checking and storing version information of a processing module used by the mobile wireless communication device is added to FIG. 3 will be described.

As shown in FIG. 47 (a), a list of items described in the module use history table 3003 indicates that the items of the module use history have a version in place of the use frequency or the latest use date and time. , FIG.
1 (a) and FIG. 43 (a). The version is the revision information of the processing module. For example, FIG.
, 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 procedure for updating a module in storage device 5 to a newer version using the version information shown in FIG. 47B will be described. Module update processing starts, and when a module update request, that is, a request to use a new processing module 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 a necessary processing module exists in the storage device 5 (step S1004).

If the required processing module does not exist in the storage device 5, a required 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, and then the module rewriting processor 302 writes necessary processing modules including the new processing module in the storage device 5 to the program memory 311. (Step S1010).

On the other hand, as a result of the check in step S1004, if the necessary processing module exists in the storage device 5, the module manager 301 refers to the module use history table 3003 to check the version of the processing module in the storage device 5 and the actual Is compared with the version of the processing module required for (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).

As a result of the check in step S1007,
If the version of the processing module stored in the storage device 5 is old, the required version of the processing module is downloaded from the wireless line (step S1008) and replaced with the old version processing module existing in the storage device 5 (step S1009). ). This is the storage device 5
The processing modules in will be updated to the new version,
Next, the module rewriting processor 301
Required processing modules in program memory 311
(Step S1010). Step S101
When the processing of 0 is performed, the version update processing of the processing module ends (step S1011).

Here, consider the use of a convolutional encoding processing module that is not allocated to the program memory 311 according to the example of the contents of the module use history table 3003 shown in FIG. 47B, for example. It is assumed that the required version of the convolutional encoding processing module is 4.0. The module manager 301
By referring to the module use history table 3003, it is known that the convolutional encoding processing module is stored in the storage device 5. The module usage history table 3003 indicates that the version of the convolutional encoding processing module stored in the storage device 10 is 3.1, which 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.
As a result, the version 4.0 convolutional encoding processing module downloaded via the wireless transmitting / receiving device 2 is replaced with the original old processing module and stored in the recording device 5. At the same time, the module use history table 3003 is updated. Thereafter, the new processing module is assigned to the program memory 311. Thus, each time a processing module is used, the required processing module and the version of the processing module stored in the storage device 5 are compared, and if the version of the processing module in the storage device 5 is older, the version is updated. You.

Next, an example will be described in which a user using the mobile radio communication apparatus selects a processing module to be deleted and secures free space in the storage device 5. The display device 321 and the input device 322 provided in the input / output device unit 7 allow the user to select a processing module to be deleted by himself or to input a command to delete the selected processing module. 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. When the user sets the mode for securing a free storage area in the storage device 5, the display device 321 displays the module name of the currently held processing module, the module size, and the state of the current allocation. . The user can select and specify the processing module to be deleted while viewing this display. For this purpose, the module manager 301 has a function of managing the module use history table 3003 in the module management table 300,
With reference to the contents of No. 3, at least a function of extracting information on the module name of each processing module currently held in the storage device 5, the module size, and the current assignment state is provided. The resource controller 4 displays, from the storage device 5, a function of displaying the information extracted by the module manager 301 on the display device 321 and a processing module to be deleted specified by the user operating the input device 322 in accordance with the display. Has a function to delete.

The module manager 301 refers to (a) a function for monitoring the occurrence of shortage of processing modules in the program memory 311 and (b) a module usage history table 3003 when the processing modules are short.
It has a function of controlling the order of replacing the processing modules in the program memory 311, determining whether or not to replace the modules, and controlling the timing of the replacement. When a processing module allocation request is issued from the module manager 301 to the module rewriting processor 302, the processor 302 writes the processing modules obtained by downloading via a wireless line or loading from the storage device 5 into the program memory 311.
When the signal processing procedure (processing module) written in the program memory 311 is executed by the DSP 310, the function realized by the written processing module is realized in the mobile wireless communication device.

The module name in the module use history table 3003 is accompanied by information on the file capacity of the corresponding processing module. The module manager 301 uses the information on the file capacity to allocate a processing module to the program memory 311 or replace a processing module.
Has a function of rewriting the information on the allocation state of the corresponding processing module to grasp the current state. According to this function, when the mode for managing the free space of the storage device 5 is set, the module manager 301 acquires information to be displayed on the display device 321 by referring to the module use history table 3003. The resource controller 4 causes the display device 321 to display the information acquired by the module manager 301 in a predetermined format.

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

The user can exchange the processing modules by inputting an instruction for selecting a desired wireless communication system via the input device 322. When the user specifies the use of a wireless communication system, for example, the system A via the input device 322, the specified 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 use history table 3003, and learns information of processing modules required in the designated A system from the module management table 300.

The module manager 301 knows, from the information in the module management table 300, the storage state of the currently used processing module and the allocation state of the signal processing device 3 to the resource (program memory 311). When it is determined that the processing module has been downloaded, a download request is issued for the missing processing module. 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 the processing module to the requesting mobile radio communication device.

The processing module transmitted from the base station to the mobile radio communication device is received by the radio transmitting / receiving 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, the download buffer 30
If there is enough free space to store the processing module stored in the storage module 3, the processing module is read from the download buffer 303 and stored in the storage device 5. Accordingly, the module manager 301 updates the contents of the module use history table 3003.

As a result of the check, if there is not enough free space in the storage device 5, the module manager 301
After the other processing modules stored in the storage device 5 are deleted, a storage area is secured, and the processing modules read from the download buffer 303 are stored in the storage device 5. That is, the storage device 5
When the free space of the module manager is insufficient, or when a request to secure the free space occurs, the module manager 3
In step 01, information on all processing modules stored in the storage device 5 is extracted with reference to the contents of the module use history table 3003. Module manager 3 based on the information
01, the display device 321 is controlled, and a list of module names, module sizes, and states (current use states) of the processing modules are displayed. From this display, the user can know the module name and capacity of the processing module currently held in the storage device 5 and whether or not each processing module is used. The user searches the display for a processing module whose status is not in use, that is, whose allocation status is OFF. If 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 deletion of the selected processing module. According to this instruction, the corresponding processing module in the storage device 5 is deleted by the resource controller 4. Further, the information regarding the deleted processing module is deleted from the module use history table 3003 by the module manager 301.

The above processing flow will be described with reference to FIG. For example, when the user specifies the mode of deleting unnecessary processing modules by operating the input device 322, the processing of FIG. 49 is executed by the module manager 301. When the module deletion starts (step S110)
1) The module manager 301 refers to the module use history table 3003 (step S110).
2) The necessary information is extracted from the information recorded in the table 3003 and displayed on the display device 321 (step S1103). When the user selects and specifies a processing module to be deleted from the displayed contents by operating the input device 322 (step S1104), the module manager 301 deletes the selected and specified processing module from the storage device 5 (step S110).
5).

FIGS. 50 (a) and 50 (b) show a module usage history table 3 similar to the example described above.
003 and the table 3003
Are shown. In FIG. 50 (c),
An example of a display screen of the history information on the display device 321 in step S1103 is shown. 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 status indicates whether or not the corresponding processing module is being used by the mobile radio communication device. If not,-is displayed.

The processing module to be deleted is designated in FIG.
This is performed by inputting the number indicating the name of the module to be deleted at the bottom of the display screen of 0 (c) using the input device 322. After that, when a confirmation instruction operation is performed, the specified processing module is deleted from the storage device 5 by the module rewriting 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 appropriately selected module may be selected from the processing modules whose allocation state is ON, and the processing module may be released and then deleted.

When the specified processing module is deleted, the contents of the module use history table 3003 are updated by the module manager 301 (step S1106). Step S1102-11
The operation of step 06 is repeated until it is determined in step S1107 that the necessary free space in the storage device 5 has been secured. When the necessary free space is secured, the deletion of the processing module ends (step S1108). in this way,
The information on the processing module stored in the storage device 5 is displayed on the display device 321, and the user of the mobile wireless communication device refers to the information and selects the processing module to be deleted, so that the processing module of the signal processing device 3 is displayed. The signal processing function can be selected. Therefore, it is possible to customize the mobile wireless communication device to a function suitable for the usage form of the user.

In the above description, the processing modules required in the mobile radio communication device are downloaded from the radio line, that is, supplied from the network side via 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 wireless communication device via the interface 8, and necessary processing modules can be transferred from the external storage device 9 into the mobile wireless communication device. Can be stored in the storage device 5. In this way, when the mobile radio communication device needs a processing module that is in short supply or a new version of the processing module, the mobile radio communication device can be downloaded from a device other than the radio line, and the external storage device 9 stores the storage device 5 in the mobile radio communication device. By transferring and holding the processing modules stored in the storage device, backup of important processing modules can be realized. As the external storage device 9, for example, a semiconductor memory card, a hard disk drive, an MO (magneto-optical disk drive), a CD-ROM drive, a CD-R / RW drive, a DVD drive, and the like are used.

In the above description, the deletion of the processing module in the storage device 5 is performed by the module use history table 300.
3 is performed based on one of a plurality of items (for example, use frequency, latest use date and time, and module size) recorded in the third item. On the other hand, the user of the mobile radio communication device may be allowed to select an arbitrary item serving as a reference for deleting a processing module from a plurality of recorded items.
This enables the user to manage the processing modules according to various usage patterns.

(Eleventh Embodiment) FIG. 51 shows a mobile radio communication device according to an eleventh embodiment of the present invention. In the following embodiments, for simplicity, for example, two wireless communication systems (A system and B system)

The signal processing device 2 has a DSP 310 and an execution file storage unit 311 for storing a modulation / demodulation execution file (processing module) directly executable by the DSP 310. The resource controller 4 is a CPU
401, and a RAM 402 that records the current management status of the resources of the signal processing device 2. The input / output device unit 7 includes a display for displaying various information to the user, and an input device such as a keyboard and a cursor key for the user to perform operation input.

In the storage device 5, an execution file 501 and a unique telephone number file 503 for the call management system A,
An execution file 502 for the call management system B, a unique telephone number file 504, a common telephone number file 510,
A translator A 511 and a translator B 512 are stored.

Execution file 501 for call management system A
Is application software used only in the system A, and the unique telephone number file 503 is a telephone directory file for the application software.
Similarly, the execution file 502 for the call management system B is
Only the B system is application software, and the unique telephone number file 504 is a telephone directory 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 transferred to different call management systems.

The common telephone number file 510 is different from the unique telephone number files 503 and 504 for the system A and the system B, and is a telephone directory file (telephone number list) described in a common file format, for example, a text file format. File). The file 510 is
This file does not enable the use of the application software in the mobile wireless communication device even if 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 managing calls.
It has the following functions. Executable files 501 and 50
2 is a telephone directory for the call management system A and unique telephone number files 503 and 504 for the call management system A.
, The telephone number list registered in the file 503 is displayed in a list or searched.
In the execution files 501 and 502, when a desired telephone number is selected and designated by a user operation from the displayed telephone numbers, a dial call is made to the telephone number. The execution files 501 and 502 can also add a telephone number that the user desires to add to the telephone directory or delete an unnecessary telephone number. When the wireless communication system is changed or when the unique telephone number files 503 and 504 are changed, the application software performs file conversion using a translator and updates the contents of the application software. It has a function to control it.

The translator A 511 and the translator B 512 are software for converting a file format. The translator A 511 and the translator B 512 are used for mutually converting files between a common telephone number file 510 which is a common list file and a list file specific to an application used in a wireless communication system defined by a modulation / demodulation execution file. Can be

That is, the translator A 511 converts a list file unique to the application software for the A system into a common telephone number file 510 which is a common list file, and converts the common list file into a list file unique to the application software for the A system. It has a function to convert. Similarly, the translator B 512 converts the list file specific to the application software for the B system into a common telephone number file 510 which is a common list file, and converts the common list file into a list file specific to the application software for the B system. Has functions.

An operation example of the present embodiment will be described. First, it is assumed that the mobile radio communication device 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 system A, and the file is stored in the execution file storage unit 411. At this time, the CPU 401 confirms that the DSP 410 is executing a modulation / demodulation execution file (processing module) corresponding to the A system.
Recorded in M402. At this time, the call management system A dedicated to the A system is used by the user through the input / output device unit 7. Accordingly, the execution file 501 for the call management system A stored in the storage device 5 is
Read into the resource controller 4 and the CPU 401
Is executed by

A menu list “Phonebook A” which is a list of the telephone numbers of the frequent destinations of the user (ie, a unique telephone number file 503 for the call management system A)
(A list of telephone numbers based on the Internet) is issued on the display through the input / output device unit 7. At this time, the CPU 401 in the resource controller 4 reads out the contents of the unique telephone number file 503 for the call management system A read from the storage device 5 into the resource controller 4 and the input / output device unit 7.
Is displayed on the display device.

When the user refers to the display of the telephone number file on the display device and makes a call or when a call is received, if there is telephone number information to be newly added to the menu list, the additional It is possible to 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 finishes using the call management system A, the CPU 401 executing the execution file 501 for the call management system A stores the rewritten unique telephone number file 503 for the call management system A in the 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 stored in the translator A5 stored in the storage device.
The data is converted into the format of the common telephone number file 510 by the management server 11 and managed. As a result, the modulation / demodulation execution file executed by the DSP 410 is converted from a file format compatible with the A system to a file format compatible with the B system, and the telephone number information is used even when another call management system is used. Is possible.

More specifically, when the user finishes using the call management system A (application software that is the execution file 501 for the call management system A) or when the modulation / demodulation execution file executed by the DSP 410 is From the file format corresponding to
Converted to a file format compatible with the system,
When 02 is rewritten, the CPU 401 executes the translator A511. Thus, the translator A 511 converts the unique telephone number file 503 for the call management system A into a common file format,
The converted telephone number file 5
10 is overwritten.

Hereinafter, the flow of this processing will be described with reference to FIG. In an initial state, it is assumed that the user having the mobile wireless communication device is located in the service area of the A system, and the mobile wireless communication device functions as a terminal compatible with the A system. Thereafter, when the user moves and the distance between the system A and the base station increases, the reception electric 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 system A. At this time, it is assumed that the user is in the service area of the B system and the mobile radio communication device is in a state where a sufficient reception electric field strength can be secured for the base station of the B system.

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

According to the unique telephone number file 503 for the call management system A last updated by this point, the translator A 511 transmits the common telephone number file 5
It is checked whether or not 10 has been overwritten (step S2002). If not, the translator A 512 is executed by the resource controller 4. As a result, the unique telephone number file 503 for the call management system A is converted into the common file format, and the converted file overwrites the common telephone number file 510 (step S2003). Thereafter, the process proceeds to step S2004. As a result of the check in step S2002, if it is overwritten, the process proceeds to step S200
Proceed to 4. Step S2004 is not always necessary, but in this step S2004, the user activates the "phone book B" of the call management system B.

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

As described above, the unique telephone number files 503 for the call management system A and the call management system B
And 504 are described in a file format that can be used only by the corresponding call management systems A and B, respectively. When the content of the file 503 or 504 is changed, the changed file is temporarily converted into a common file format and stored as a common telephone number file 510. When the wireless communication system used by the mobile wireless communication device is changed, the common telephone number file 510 is converted into a file so that it can be used under the changed wireless communication system. That is, at a stage before the wireless communication system used by the mobile wireless communication device is changed, even if the content of the file 503 or 504 is changed,
Next, the file in which the change is reflected can be used under another wireless communication system used by the mobile wireless communication device.

Therefore, the user can use the unique telephone number file 5 for the call management system A that has been changed in the A system.
03 can be reflected in the unique telephone number file 504 for the call management system B after the transfer to the B system, and the reflected "Phonebook B" can be used (step S2006). That is, when the menu list “Phonebook B”, which is a list of frequently used telephone numbers in the call management system B used only in the B system, is displayed, the call management system A used in the A system is updated. The contents of the menu list “Phonebook A” can be used as it is. This eliminates the need for the user to individually manage data for different wireless communication systems, and allows the user to use his / her latest telephone directory regardless of which wireless communication system is used.

In the above description, it is assumed that 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.
These files 503 and 504 may be temporary files generated on the memory in the resource controller 4 as necessary.

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.
The unique URL file 604 is described in a file format that can be used only by the web browser B. Therefore, the Web browser A cannot specify the Web page address without using the URL file described in the dedicated file format. 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 form of a common list file, and when the wireless communication system used by the mobile wireless communication device is changed, the format of the common list file is changed by the translator.

The URL information of page b can be added to the favorite menu list. In that case, when the user performs a registration operation to the favorite menu list, the resource controller 4 executes the CPU 401 executing the web browser A.
Stores the new URL information to be registered in the resource controller 4 in the web browser A-specific U
Add it to the RL file 603. Thereafter, when the user finishes using the web browser A, the CPU 401 sets the added web browser A-specific URL file 60.
3 is stored in the storage device 5. Thereby, the unique URL file 603 for the web browser A stored in the storage device 5 is updated.

Since the unique URL file 603 for the web browser A thus updated in the storage device 5 has a file format exclusive for the web browser A, it cannot be referenced or updated by the web browser B. Therefore, the unique URL file 6 for web browser A
03 is converted to a file in the common file format,
It is stored in the storage device 5 as the L common file 610.

According to this embodiment, the rewritten URL information of the unique URL file 603 for the web browser A is stored in the translator A 61 stored in the storage device 5.
1 is converted into the format of the URL common file 610 and managed. As a result, even when the modulation / demodulation execution file executed by the DSP 410 is changed from a file corresponding to the A system to a file corresponding to the B system, the URL is used even when the web browser B is used.
Enables the use of information.

Specifically, at the time when the user finishes using the web browser A, or when the execution file for modulation / demodulation executed by the DSP 410 is converted from the file format compatible with the A system to the file format compatible with the B system. When the RAM 402 is rewritten, the CPU 401 executes the translator A 611. As a result, the translator A 611 converts the unique URL file 603 for the web browser A into a common file format, and the converted file overwrites the common URL file 610.

The flow of this process will be described below with reference to FIG. In an initial state, it is assumed that the user having the mobile wireless communication device is located in the service area of the A system, and the mobile wireless communication device functions as a terminal compatible with the A system. At this time, the resource controller 4 changes the modulation / demodulation execution file executed by the DSP 410 to a file corresponding to the system B stored in the execution file storage unit 411, and this change is stored in the RAM.
402 is recorded (step S2011). After this,
When the user moves and the distance between the system A and the base station increases, the reception electric 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 system A. At this time, it is assumed that the user is in the service area of the B system and the mobile radio communication device is in a state where a sufficient reception electric field strength can be secured for the base station of the B system. As described above, the mobile radio communication device cannot know that the line with the system A can be maintained, and instead can know that the line with the system B can be secured.

It is checked whether or not the translator A 611 has overwritten the common URL file 610 according to the unique URL file 603 for the web browser A last updated at this time (step S2).
012). If not, the translator A 611 is executed by the resource controller 4. Thereby, the unique URL file 60 for the web browser A
3 is converted into the format of the common URL file 610, and the converted file overwrites the common URL file 610 (step S2013). Thereafter, the process proceeds to step S2014. Step S2014 is not always necessary, but in this step S2014, the user activates the "favorite" of the Web browser B.

In the next step S2015, the translator B 612 is activated, and the translator B 612 converts the file format of the common URL file 610 into the file format of the Web browser B-specific URL file 604, and generates or overwrites the URL file 604. Is done.

As described above, the unique URL files 603 and 60 for the web browser A and the web browser B are used.
4 is described in a file format that can be used only by the corresponding web browsers A and B. Therefore, if the Web browser A does not use a unique URL file described in a dedicated file format, Web browser A
b cannot be used for page designation,
If a unique URL file described in a dedicated file format is not used, a favorite Web page cannot be specified even if it is found and registered in the file. According to the present embodiment, the unique URL file is converted to a URL common file 610 which is a common file format.
By converting the URL common file 610 into a file format compatible with the web browser to be used, so that the web browser can use the file. In this way, a list of Web pages based on the browser-specific URL file can be used. A user who has shifted from the A system to the B system needs the unique URL file 604 for the web browser B to display the favorite menu list in the web browser B used only in the B system. According to the present embodiment, the unique UR for the web browser B in which the changed content is reflected by the file format conversion
Since the L file 604 can be obtained, when the favorite menu list is displayed, the contents of the favorite menu list updated by the web browser A used in the system A can be directly reflected (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 web browser A
It is assumed that the unique URL files 603 and 604 for the web browser B and the web browser B exist on the storage device 5. However, these files 603 and 604 are temporarily It may be a file.

(Thirteenth Embodiment) A mobile radio communication apparatus according to a thirteenth embodiment of the present invention shown in FIG.
The mail system A and the mail system B are stored in the storage device 5.
Execution files 701 and 702, a unique received mail file 703 for mail system A and mail system B
704, a received mail common file 710, and translators A711 and B712.

Executable files 701 and 702 are A files that are used only in the A system and only in the B system, respectively.
This is a mail system specific to the system and 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.

The mail files 703 and 704 are received mail files described in a unique 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 A 711 and B 712 are
File conversion application software for mutually converting a file format between a received mail common file 710 and a unique received mail file having a unique file format in a mail system used in a wireless communication system defined by a modulation / demodulation execution file It is. The translator A 711 is a unique received mail file 70 for the mail system A, which is a received mail file unique to the mailing application software for the A system.
3 has a function of converting the received mail common file format into a 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 70
3 and 704 are both read by the resource controller 4 and executed by the controller 4 to realize the functions.

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

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

At this time, the input / output device unit 7
Is a 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 is executed by the CPU 401 in the resource controller 4 so that the mail system A can be used. Has become.

The user inputs a menu list “received mail”, which is a list of received mails sent to the user and stored in the storage device 5, to the input / output device unit 7.
Make the request shown on the display through. 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 view the received mail, reply to the received mail, or add any newly received mail to this list. In that case, C
The contents of the new received mail are first read by the PU 401 into the unique received mail file 70 for the mail system A read into a memory (not shown) in the resource controller 4.
Added to 3. Thereafter, when the user finishes using the mail system A, the CPU 401 causes the storage device 5 to store the added mail system A specific received mail file 703.

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

More specifically, when the user finishes using the mail system A, or when the modulation / demodulation execution file being executed by the DSP 410 is converted from a file corresponding to the A system to a file corresponding to the B system, When the RAM 402 is rewritten, the CP
U401 executes translator A712. Thereby, the unique received mail file 70 for the mail system A
3 is converted to a common file format by the translator A 710, and the converted received file overwrites the common received mail file 420.

The flow of this process will be described below with reference to FIG. In an initial state, it is assumed that the user having the mobile wireless communication device is located in the service area of the A system, and the mobile wireless communication device functions as a terminal compatible with the A system. At this time, the resource controller 4 changes the modulation / demodulation execution file executed by the DSP 410 to a file corresponding to the system B stored in the execution file storage unit 411, and this change is stored in the RAM.
Recorded in 402 (step S2021). After this,
When the user moves and the distance between the system A and the base station increases, the reception electric 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 system A. At this time, it is assumed that the user is in the service area of the B system and the mobile radio communication device is in a state where a sufficient reception electric field strength can be secured for the base station of the B system. As described above, the mobile radio communication device cannot know that the line with the system A can be maintained, and instead can know that the line with the system B can be secured.

The translator A 712 checks whether or not the common received mail file 710 has been overwritten in accordance with the mail system A specific received mail file 703 that was last updated up to this point (step S2022). At this point, the file format is converted by the translator A 712 from within the mail system A-specific received mail file 703,
Common received mail file 42 according to the converted file
0 is overwritten (step S2023). Thereafter, the process proceeds to step S2024. Step S2024
Is not always necessary, but the step S20
At 24, the user activates the "inbox" of the mail system B.

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 unique received mail file 704 for the mail system B, and generates the received mail file 704. Or it is 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, by the file conversion, when the user displays the menu list “Inbox” which is a list of received mails of the mail system B, the user can directly reflect the contents of the menu list “Received mail” updated by the mail system A. It is possible (step S2026). The user does not need to individually manage such data for each different wireless communication system, and the convenience is greatly improved.

In the above description, the mail systems A and B
It is assumed that the unique receiving mail files 703 and 704 exist on the storage device 5.
And 704 may be temporary files generated on a memory (not shown) in the resource controller 4 as necessary. In the above description, the received mail is replaced with the transmitted mail, and the information of the mail transmitted by the user in the past can be managed in exactly the same manner as described above. The same management as described above can be performed on the mail address information of a partner who frequently sends and receives mails.
