[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mobile communication system such as a mobile phone system and a PHS (Personal Handyphone System), and more particularly, to a mobile communication system having a function of remotely managing software of a mobile station from a network side via a wireless line The present invention relates to a management apparatus and a mobile station apparatus used in this system.
[0002]
[Prior art]
In recent years, mobile communication terminals such as mobile phone terminals and PHS terminals are rapidly spreading with increasing mobile communication needs. This type of terminal generally includes a wireless unit that performs transmission and reception operations of a wireless signal, an input / output unit having an input key, a liquid crystal display, and the like, and a baseband processing unit. Among these, the baseband processing unit has a control unit using a microprocessor or DSP (Digital Signal Processor), and performs various communication control, audio signal code decoding processing, and the like by software control.
[0003]
By the way, such a mobile communication terminal may require rewriting of software after purchase of the terminal. This is the case, for example, when the network side starts a new service such as an e-mail transmission / reception function or a browser function addition, or when a defect such as a bug occurs in the software. In such a case, conventionally, for example, a user brings a mobile communication terminal to a service station and connects a maintenance terminal device such as a personal computer to an external connector of the mobile communication terminal. This personal computer can cope with this by rewriting software stored in the program memory via the control unit of the mobile communication terminal.
[0004]
[Problems to be solved by the invention]
However, with such a conventional software management method, the user must bring the terminal to the service station each time, and much time and effort are required to rewrite the software, which is extremely inefficient. In some cases, the terminal cannot be brought to the service station for the convenience of the user, and it is difficult to rewrite the software for all terminals.
[0005]
On the other hand, as another software management method, it is considered that the software of the mobile communication terminal is rewritten from the network side via a wireless line. When this type of technique is used, the software can be rewritten without bringing the terminal into the service station. Therefore, the software can be rewritten efficiently and efficiently for a large number of target terminals.
[0006]
However, there are many different types of mobile communication terminals, and since there are many cases in which different hardware (microprocessor, DSP, etc.) and software are adopted for each model, terminals that require software rewriting. There are many problems that must be solved in the implementation, such as how to identify the current situation, and the current situation has not yet been realized.
[0007]
The present invention has been made paying attention to the above circumstances, and its object is to provide a mobile communication system capable of efficiently and accurately changing software of a mobile station, its management device, and mobile station device There is to do.
[0008]
[Means for Solving the Problems]
  In order to achieve the above object, the present invention comprises a plurality of mobile stations having a circuit unit operated by software, and a network side including a management apparatus management apparatus in which these mobile stations are connected via a wireless line. A mobile communication system,
  The mobile station comprises software storage means for storing its own software in a rewritable state, and receiving means for receiving management information of software used by the mobile station from the mobile station on the network side. In order to notify the mobile station when it becomes necessary to change the software used by the mobile stationDo not ring the mobile stationWhen communication is established with the transmission means for transmitting the notification signal and the mobile station, the software stored in the software storage means of the corresponding mobile station based on the software management information received by the reception means Transmission means for transmitting rewrite information for rewriting the wear to the mobile station,
  Furthermore, the mobile stationWhen the notification signal is received from the network side, it is determined whether the notification signal is a notification signal that does not ring or a normal incoming call notification signal that arrives with transmission from another terminal, and the notification signal that does not ring If it is determined that the notification signal is received from the network side, it will not ring and the notification signal is received.Rewriting means for re-establishing communication with the network side and then rewriting the software stored in the software storage means based on the received rewriting information when receiving the rewriting information from the network side. It is characterized by having.
[0009]
  Therefore, according to the present invention,On the network side, the software management information of each mobile station is received, and information to be updated on the basis of the software management information is transmitted.For this reason, for the network side, even if the number of mobile stations is large and the types are different and the software is different, the network side can update the software accurately and in a short time for the mobile station. it can. In addition, since software rewriting is performed remotely via a wireless line, software rewriting can be completed in a relatively short period of time for a large number of mobile stations. That is, for the network side, it is possible to change software extremely efficiently for a large number of mobile stations of various types. On the other hand, there is no need for the subscriber to bring his / her own terminal to the service station, and there is an advantage that necessary software changes can be made quickly and reliably while using the terminal normally.
In addition, by transmitting a notification signal that does not ring the mobile station from the network side, it is possible to prevent the mobile station from ringing when updating software. In this way, for example, when updating software that is not very important at midnight, etc., it is possible to update the software without notifying the user one by one. .
[0010]
  This inventionThe mobile station further comprises management information transmitting means for transferring management information of its own software to the network side via a wireless line, and the network side receives the management information transmitted by the management information transmitting means. It is further characterized by further comprising means for judging a rewrite location that needs to change the software used by the mobile station based on the received management information received by the receiving means.
[0011]
  With this configuration, the network sideIt is possible to determine which part of the mobile station needs to update the software, and the software can be updated efficiently. That is, when a part of the software is changed, it can be dealt with by rewriting a part including the changed part. For this reason, the software can be changed efficiently in a short time as compared with the case where the entire software is rewritten.
[0014]
  Also, in the present invention, when communication is established between the mobile station and the network side, if the predetermined transmission quality does not reach a predetermined level in the mobile station, the subsequent writing means You may make it have the function to stop writing of software.
[0015]
  By configuring in this way,It is possible to prevent the mobile station from erroneously writing software due to a transmission error and an increase in software reception time due to deterioration in transmission quality.
[0018]

The input / output I / F 32 has a man-machine interface function for a key input unit and a display unit, and an interface function for an external storage medium such as a DVD, CD-ROM, FDD, etc. It also has a communication interface function for transferring information to and from the personal computer.
[0024]
The storage unit 33 includes a management information database 33a. In the management database 33a, management information of software used by the mobile stations MS1 to MSn is stored for each of the mobile stations MS1 to MSn.
[0025]
The control unit 30 includes management information registration control means 30a and software change control means 30b. When the management information registration control means 30a receives a registration request for software management information from the mobile stations MS1 to MSn to be managed, the management information registration control means 30a receives the management information of the software from the mobile stations MS1 to MSn in response to this request. Then, the received management information is registered in the management information database 33a.
[0026]
FIG. 4 shows an example of the registration result of management information in the management information database 33a. The model information U1, U2,... Of each mobile station MS1 to MSn, the software versions V2, V3,. And serial numbers W2, W3,... Are stored in association with the telephone numbers DN1, DN2,. The type of microprocessor used by the mobile station and the OS (Operating System) can be identified by the model information U1, U2,.
[0027]
When a software change instruction is input via the input / output unit 32, the software change control unit 30b creates a list of target mobile stations by referring to the storage contents of the management information beta base 33a. At the same time, software rewrite information corresponding to the software management information is created for each mobile station. Then, a silent link is sequentially made to the target mobile station to form a communication link, and the software rewrite information is transmitted through the communication link to perform software rewrite processing.
[0028]
Next, the mobile stations MS1 to MSn are configured as follows. FIG. 3 is a circuit block diagram showing the configuration. Here, a mobile phone terminal used in a mobile communication system adopting the TDMA system is illustrated.
[0029]
In the figure, a radio frequency signal arriving from a base station (not shown) via a radio communication channel is input to a receiving circuit (RX) 3 via an antenna 1 and an antenna duplexer (DUP) 2, where a frequency synthesizer ( (SYN) 4 is mixed with the reception local oscillation signal output from 4 and converted into a reception intermediate frequency signal. The received intermediate frequency signal is sampled by the A / D converter 7 and then input to the digital demodulator circuit (DEM) 6. The demodulator circuit 6 performs frame synchronization and bit synchronization and then digitally demodulates the received intermediate frequency signal. The
[0030]
The reception circuit 3 is provided with a reception electric field strength detector, and the reception electric field strength RCS of the radio carrier signal detected by the reception electric field strength detector is controlled by a control circuit ( CONT) 20. In addition, synchronization information obtained by the frame synchronization and the bit synchronization is also input to the control circuit 20.
[0031]
The digital demodulated signal output from the digital demodulating circuit 6 includes a digital speech signal and a digital control signal. Of these, the digital control signal is taken into the control circuit 20 and identified. On the other hand, the digital speech signal is subjected to error correction decoding by an error correction decoding circuit (CHDEC) 8. The digital call signal subjected to error correction decoding is subjected to a voice decoding process by a voice decoding circuit (SPDEC) 9, further converted back to an analog call signal by a D / A converter 10, and then supplied to a speaker 11. Then, the loudspeaker 11 outputs a loud sound.
[0032]
On the other hand, the transmission signal inputted by the microphone 12 is sampled by the A / D converter 13 and then inputted to the speech coding circuit (SPCOD) 15 via the acoustic echo canceller (AEC) 14, where the speech coding is performed. It becomes. The coded digital transmission signal obtained by this voice coding is subjected to error correction coding in the error correction coding circuit (CHCOD) 16 together with the digital control signal output from the control circuit 20, and then the digital modulation circuit ( MOD) 18.
[0033]
The digital modulation circuit 18 generates a modulation signal corresponding to the encoded digital transmission signal. The modulation signal is converted into an analog signal by the D / A converter 17 and then input to the transmission circuit (TX) 5. . In the transmission circuit 5, the modulation signal is frequency-converted into a transmission radio frequency signal, and then power is amplified. The radio frequency signal output from the transmission circuit 5 is transmitted from the antenna 1 to a base station (not shown) via the antenna duplexer 2.
[0034]
Reference numeral 19 denotes a key input unit (KEY), which is provided with a call key, an end key, a dial key, and various function keys. Reference numeral 21 denotes a liquid crystal display (LCD), which displays dial information of the caller, the operating state of the apparatus, and the like. An external interface (external I / F) 24 is connected to a personal computer or an IC card (not shown).
[0035]
The power source includes a battery 23 made of, for example, a lithium ion battery, and the output voltage is supplied to a power circuit (POW) 22. The power supply circuit 22 generates a predetermined operating voltage Vcc based on the output voltage of the battery and supplies power to each circuit in the apparatus.
[0036]
By the way, the control circuit 25 has a microprocessor as a main control unit, and in addition to a normal control function as a mobile station such as wireless communication control and call control, the control circuit 25 is managed as a new function related to the present invention. Information transmission control means 20a and software rewrite control means 20b are provided.
[0037]
The management information transmission control means 20a transmits its own software management information via the communication link to the software management center CC at the time of the first test call after the purchase of the mobile station. As described above with reference to FIG. 4, the software management information includes a telephone number, model information, the version of software being used, and a manufacturing number.
[0038]
The software rewrite control means 20b, when new software is transferred together with the software rewrite information after the communication link is formed by the silent incoming call from the software management center CC, the storage unit 25 according to the software rewrite information. The software to be changed is rewritten to the new software described above.
[0039]
As shown in FIG. 5, for example, the software structure of the mobile station includes basic software (OS: Operating System), a software rewrite control program (SWC) functioning on the OS, a hardware driver HW, The program includes a physical layer control program L1, protocol layer control programs L2 and L3, and other application programs A.
[0040]
Among these, the basic software and the rewrite control program are stored in the ROM so that they cannot be rewritten. On the other hand, the hardware driver HW, the physical layer control program L1, the protocol layer control programs L2 and L3, and the other application program A are each composed of a plurality of blocks HW1, HW2, and HW3 as shown in FIG. , L11, L12, L13, L21, L22, L23, L31, L32, L33, and A1 to A6, and then stored in the flash memory in a rewritable state.
[0041]
Next, the operation of the mobile communication system configured as described above will be described.
First, registration control of software management information is performed as follows. FIG. 6 is a flowchart showing the control procedure and control contents.
[0042]
That is, in the mobile stations MS1 to MSn, a test call is made in step 6a after purchase. The software management center CC monitors the arrival of the test call in step 7a. When a test call arrives from the mobile station MSi in this state, the software management center CC communicates with the caller mobile station MSi in step 7b. A process for forming a link is executed. At this time, the caller mobile station MSi also executes processing for forming a communication link with the software management center CC in synchronization with the communication link formation procedure by the software management center CC.
[0043]
When a communication link is formed with the software management center CC, the mobile station MSi moves from step 6b to step 6c, where it reads out its own software management information from the storage unit 25. To the software management center CC. The software management information transmitted at this time is composed of its own telephone number, model information, software version in use, and serial number.
[0044]
On the other hand, when the software management information is sent from the caller mobile station MSi, the software management center CC receives the software management information in step 7c and then registers it in the management information database 33a in step 7d. Execute the process for As a result, in the management information database 33a, for example, as shown in FIG. 4, model information U1, U2,..., Software versions V2, V3 in use are associated with the telephone numbers DN1, DN2,. ,... And serial numbers W2, W3,.
[0045]
When the registration of the software management information coming from the caller mobile station MSi is completed, the software management center CC moves from step 7e to step 7f, where it registers with the caller mobile station MSi. A completion notification is transmitted, and subsequently the end-call processing is executed in step 7g to return to the standby state.
[0046]
On the other hand, the calling mobile station MSi monitors the arrival of the registration completion notification in step 6d after completing the transmission of the software management information. When the registration completion notification is received from the software management center CC, the calling station MSi ends in step 6e. Talk processing is executed to shift to the standby state.
[0047]
Thereafter, similarly, the software management information of all the mobile stations MS1 to MSn is registered in the management information database 33a of the software management center CC using a test call made immediately after purchase.
[0048]
Now, in this state, it is assumed that it is necessary to partially change software of an arbitrary model among the mobile stations MS1 to MSn being used in the system. Then, software change processing is performed between the software management center CC and the mobile stations MS1 to MSn as follows. FIG. 7 is a flowchart showing the control procedure and control contents.
[0049]
That is, it is assumed that it is necessary to upgrade a call control program used for a mobile station of a specific model or to correct a defect found in a part of the call control program. In this case, for example, the manufacturer or the operator in charge of the telecommunications carrier designates the model to be changed in the software management center CC, inputs new software using a storage medium or the like, and inputs a software rewrite instruction. .
[0050]
Then, the software management center CC moves from step 9a to step 9b, where the stored contents of the management information beta base 33a are referred to and a list of mobile stations that are subject to software change is created. Then, in step 9c, the ringing calls are made one by one to the mobile stations subject to software change according to the above list, and the process for forming the communication link is executed in step 9d.
[0051]
When a communication link is formed with an arbitrary mobile station MSj for which software is to be changed, the software version used by the mobile station MSj is stored in the management information database 33a in step 9e. Based on the above, a software block (for example, L21) to be rewritten is determined. Then, software rewrite information for designating this block L21 is created, and this information is transmitted to the mobile station MSj. Subsequently, in step 9f, an object code of software to be rewritten is transmitted.
[0052]
Thereafter, similarly, for all software blocks to be rewritten, software rewrite information for designating the software blocks and the object code of the software to be rewritten are repeatedly transmitted. When the transmission of the rewrite information and the object code for all software blocks is completed, the software management center CC transmits a rewrite information transmission completion notification to the mobile station MSj.
[0053]
On the other hand, each mobile station MS1 to MSn monitors the generation of a call and the arrival of an incoming call in steps 8a and 8b in the standby state. In 8c, it is determined whether or not this incoming call is a silent incoming call. For example, when a normal incoming call is received from another user, an incoming call notification unit such as a ringing tone generator or a vibrator is driven as it is to execute a normal incoming call process.
[0054]
In contrast, it is assumed that a silent incoming call is received from the software management center CC requesting software change. Then, the mobile station MSj moves to step 8d and executes processing for forming a communication link here. When the communication link is formed, the software rewriting program is started in step 8e. This software rewrite program maintains the communication link in place of the physical layer control program L1 and the protocol layer control programs L2 and L3 during the period when the communication link with the software management center CC is formed. The software rewrite information and the rewrite software object code received from the software management center CC are received.
[0055]
Upon receiving the software rewrite information, the mobile station MSj selects the software block L21 designated by the rewrite information in step 8f, and writes the object code in the selected block L21 in step 8g.
[0056]
Thereafter, each time new software rewrite information and rewrite software object code are received from the software management center CC, the software object code to be rewritten is added to the software block specified by the software rewrite information. Repeat the writing process.
[0057]
Then, when the rewriting of the software object code is completed for all the software blocks to be rewritten and a transmission completion notification is received from the software management center CC, the mobile station MSj sends a rewriting completion notification to the software management center CC. Send to. Then, the process proceeds from step 8h to step 8i, where the end-of-call process is performed, and the standby state is restored.
[0058]
On the other hand, when the software management center CC receives the rewriting completion notification from the mobile station MSj, the software management center CC updates the software management information related to the corresponding mobile station in the management information database 33a. Then, the process proceeds from step 9g to step 9h, and here the call termination process is executed.
[0059]
Finally, in step 9i, the software management center CC determines whether or not the software rewrite control for all mobile stations to be rewritten previously listed in step 9b has been completed. If any mobile station that has not been rewritten still remains, the process returns to step 9c to make a silent call to this mobile station, and thereafter the software rewrite control in steps 9c to 9h is repeated.
[0060]
As described above, in this embodiment, software management information is transmitted from the mobile stations MS1 to MSn using the test call, and this information is registered in the management information database 33a of the software management center CC. . When the software of the mobile stations MS1 to MSn is changed, the software management center CC lists the mobile stations to be changed based on the registered contents of the management information database 33a, and for each mobile station. The software to be rewritten is specified in block units, and this specified information is transferred to the mobile station via the communication link together with the software object code, so that the software used by the mobile station can be selected selectively. I try to rewrite it.
[0061]
Therefore, for mobile station manufacturers or carriers, even if the number of mobile stations MS1 to MSn is large, the models are various, and the software is different from each other, the mobile stations to be changed are not missed accurately and in a short time. Since the software can be rewritten remotely via a communication link, the software rewriting can be completed in a short period of time for a large number of mobile stations MS1 to MSn. .
[0062]
On the other hand, the user of the mobile station does not need to bring his / her own terminal to the service station, so that it is possible to respond quickly and reliably to software upgrades and the like without any trouble.
[0063]
In addition, since the manufacturer or the communication carrier can collect and register the software management information of each mobile station MS1 to MSn using a test call, the software management information of a huge number of mobile stations can be registered. It can be registered and managed effectively.
[0064]
Furthermore, since the software of the mobile stations MS1 to MSn is divided into a plurality of blocks for each type and layer, and the software is rewritten in units of blocks, the software is always compared with the case where the entire software is rewritten. The time required for the software rewriting process can be greatly shortened to improve the processing efficiency, and the capacity of the buffer memory required for the mobile station can be reduced.
[0065]
The present invention is not limited to the above embodiment. For example, the software rewrite information and the object code transmitted from the software management center CC to the mobile station are temporarily stored in the buffer memory by the mobile station and then returned to the software management center CC. Then, the software management center CC may collate the returned information with the original information that has been transmitted, and if the two match, the software management center CC may be configured to instruct the mobile station to write. In this way, it is possible to always perform accurate rewriting while reducing the influence of transmission errors and the like.
[0066]
In addition, the software after rewriting may be transmitted from the mobile station to the software management center CC to check the correctness, and further, a test call may be made by the software after the completion of writing. The operation may be confirmed by the software management center CC, and if it does not operate normally, rewriting may be executed.
[0067]
In order to prevent erroneous writing of software due to transmission errors, the mobile station receives a received electric field strength or BER (Bit Error Rate) in a state where a communication link is formed between the software management center CC and the mobile station. The transmission quality is judged based on the presence or absence of interference. When the judgment result of the transmission quality is less than the predetermined level, the software management center CC is notified of this and the software writing control to the mobile station is performed. May be canceled.
[0068]
Further, in the mobile station, new software information received from the software management center CC is temporarily stored in the buffer memory, and a test call is made to the software management center CC based on the received software. . Then, the operation is confirmed by the software management center CC, and when it is confirmed that the operation is normal, the software management center CC gives a write instruction to the mobile station, and the buffer software is written in the regular memory. You may comprise as follows.
[0069]
Furthermore, the software rewrite control for the mobile station may be executed by selecting a time zone during which the user's usage frequency is reduced, for example, midnight. In this way, the software can be changed with little influence on the normal use state by the user.
[0070]
At that time, the software management center may notify the mobile station in advance by sending a software change notification to the mobile station using e-mail or the like so that the mobile station is turned on at night.
[0071]
Further, the user may return an approval for the software change notification, and the software change control may be executed only for the user whose approval is confirmed.
[0072]
In the above embodiment, the software management center CC is connected to the mobile communication switching device MNW via a communication line. However, the software management center CC may be provided in the mobile communication switching device MNW as part of station equipment. Alternatively, each base station BS1 to BSm may be provided.
[0073]
Further, the present invention can be applied to a wireless communication system adopting a CDMA system in addition to existing systems such as PHS, PDC (Personal Digital Cellular), and GSM (Global System For Mobile Communication).
[0074]
In addition, the configuration of the software management center and the mobile station, the procedure and contents of software registration control and software rewrite control, and the like can be modified in various ways without departing from the gist of the present invention.
[0075]
【The invention's effect】

In order to notify the mobile station to that effect by the above transmission meansDo not ring the mobile stationWhen a notification signal is transmitted and communication with the mobile station is established based on the transmission of the notification signal, the transmission unit performs the corresponding movement based on the software management information registered in the management information storage unit. Rewrite information for rewriting the software stored in the software storage means of the station is transmitted to the mobile station. On the other hand, when the mobile station is provided with software rewriting means and receives the notification signal from the network side,It is determined whether the notification signal is a notification signal that is not ringed or a normal incoming call notification signal that arrives with a call from another terminal. After receiving the notification signal, and after receiving the notification signalWhen communication with the network side is established and then the rewrite information is received from the network side, the software stored in the software storage means is rewritten based on the received rewrite information.
