(First embodiment)
Hereinafter, a mobile phone system and a control method of the mobile phone system according to a first embodiment of the present invention will be described in detail with reference to the accompanying drawings.

  First, the configuration of the mobile phone system according to the first embodiment of the present invention will be described in detail.

  FIG. 1 is a functional block diagram showing a configuration of a mobile phone system as an example of the first embodiment of the present invention. Referring to FIG. 1, the mobile phone system according to the present embodiment includes a mobile phone terminal 1, a base station 100, a gateway 200, and a server 300. Communication between the mobile phone terminal 1 and the base station 100 is performed wirelessly. The base station 100 and the gateway 200 are connected by a telephone network, and the gateway 200 and the server 300 are connected by an Internet network.

  The cellular phone terminal 1 includes a CPU unit 10, a flash ROM 11, an operation unit 12, a wireless unit 13, and a RAM 15. The CPU unit 10 is connected to the flash ROM 11, the operation unit 12, the radio unit 13, and the RAM 15 via an internal bus (not shown), and can control each unit. Note that various configurations other than the above-described configuration, such as a display unit, a speaker, a microphone, a battery, and the like, are not directly related to the present invention, and thus the detailed configuration and description of the operation are omitted. .

  The CPU unit 10 has a function as a control unit that controls a peripheral part of the mobile phone terminal 1 to realize a series of operations as the mobile phone terminal 1.

  The flash ROM 11 is a storage device using a rewritable nonvolatile semiconductor memory exemplified by a NOR flash memory, a NAND flash memory, and the like. The flash ROM 11 here is a non-volatile storage unit that functions as a main storage device that the CPU unit 10 can directly read and write. The flash ROM 11 includes a program area 21 and a data area 22.

  The program area 21 stores a startup (boot) program executed by the CPU unit 10 when the mobile phone terminal 1 is started. The boot program stored in the program area 21 has a minimum necessary function for reading and starting the system program of the mobile phone terminal 1 from the outside. And the capacity of the boot program is kept to a minimum. In the boot program, the server 300 is registered in advance as an automatic connection destination. Further, by using the rewritable flash ROM 11, for example, when a boot program such as an address change of the server 300 needs to be corrected, it can be freely updated.

  In the data area 22, various data such as setting information of the mobile phone terminal 1 can be stored. Examples of stored data include start history information for each application program executed after the mobile phone terminal 1 is started. This activation history information includes the number of activations, the activation date and time, and the like. Such data does not have a large file size like a program that becomes larger due to higher functionality.

  In this manner, the flash ROM 11 according to the present embodiment only needs to have a capacity necessary for storing these programs and data, and the cost can be reduced.

  The operation unit 12 is an input device exemplified by a keyboard, a touch panel, and the like, and includes keys (buttons) for performing operation decision, cancellation, character string input, and the like by the user.

  The wireless unit 13 is a device that performs communication processing exemplified by a baseband LSI (Large Scale Integration). The wireless unit 13 includes an antenna 14. The wireless unit 13 controls wireless communication between the base station 100 and the mobile phone terminal 1 via the antenna 14 and exchanges information such as notification of a wireless state with the CPU unit 10.

  The RAM 15 is a main storage device exemplified by various RAMs such as a static RAM and a dynamic RAM, and is a main storage unit that functions as a work area of the CPU unit 10. A system program and application programs developed on the RAM 15 after the mobile phone terminal 1 is activated are executed by the CPU unit 10 to operate the mobile phone terminal 1. The RAM 15 can read and write data faster than the flash ROM 11.

  The base station (mobile base station) 100 is a device for performing wireless communication with a plurality of mobile phone terminals 1 and is a terminal of a telephone network (wired network). That is, it has a function as a relay point for relaying communication between the mobile phone terminal 1 and the telephone network.

  The gateway 200 is a network device for connecting the telephone network on the base station 100 side and the Internet network on the server 300 side. The gateway 200 performs protocol conversion, file format conversion, etc., and relays the connection between the telephone network and the Internet network.

  The server 300 is provided on the Internet, stores various programs used in the mobile phone terminal 1, and provides those programs in response to requests from the mobile phone terminal 1. The various programs include a system program that operates the mobile phone terminal 1 at a minimum, an application program that operates on the system program of the mobile phone terminal 1, and the like. Since the functions other than the basic functions of the mobile phone terminal 1 are realized by application programs, the capacity of the system program is also minimized. As a result, the data transfer amount of the system program to the mobile phone terminal 1 can be suppressed.

  Here, each component of the cellular phone terminal 1 according to the embodiment of the present invention described and illustrated discloses an outline of functions, and does not limit a physical configuration. That is, each component of the mobile phone terminal 1 may be configured in an arbitrary unit in a functionally or physically distributed or integrated form. For example, the CPU unit 10 and the wireless unit 13 can use devices integrated as one chip. In addition, the function that is realized by the LSI may be configured such that the CPU 10 executes the process by executing a program.

  Next, the operation of the mobile phone system according to the first embodiment of the present invention will be described in detail.

  2A and 2B are flowcharts showing operations until the mobile phone system as an example of the first embodiment of the present invention becomes available.

  With reference to FIG. 2A and FIG. 2B, the flow of processing in the cellular phone terminal 1 from when the power is turned on until the function can be used by executing the application program will be described in detail.

  First, after the mobile phone terminal 1 is turned on, for example, to reset the entire apparatus, the reset is released (step S1). As a result, the CPU unit 10, the flash ROM 11, the RAM 15, and the units in the mobile phone terminal 1 such as the operation unit 12, the radio unit 13, and the antenna 14 that are not shown in FIGS. 2A and 2B are initialized. Ready to operate.

  After reset release, the CPU unit 10 reads a boot program for starting the mobile phone terminal 1 (step S2). More specifically, the CPU unit 10 reads the boot program stored in the program area 21 (not shown in FIGS. 2A and 2B) of the flash ROM 11 built in the mobile phone terminal 1.

  The read boot program is directly executed and started by the CPU unit 10 (step S3). The boot program loads the system program of the mobile phone terminal 1 from the server 300, the gateway 200, the base station 100, the antenna 14 of the mobile phone terminal 1, and the radio unit 13 which are not shown in FIGS. 2A and 2B. It has the minimum necessary functions to download via. Therefore, at this stage, the mobile phone terminal 1 is not yet ready for use by the user.

  After starting the boot program, the CPU unit 10 issues a system program read request to the server 300 (step S4). At this time, the CPU 300 may select the system program suitable for the mobile phone terminal 1 by transmitting the information of the mobile phone terminal 1.

  In response to the read request, the server 300 transmits a read permission for the system program to the mobile phone terminal 1 (step S5).

  Receiving the system program read permission, the CPU unit 10 starts downloading the system program (step S6).

  The CPU unit 10 issues a system program download request to the server 300 (step S7).

  The server 300 that has received the system program download request transmits the system program to the mobile phone terminal 1 in response to the request (step S8).

  The CPU unit 10 expands the received system program data in the RAM 15 (step S9). Data of the system program is appropriately divided by the server 300 according to the capacity and transferred to the mobile phone terminal 1, and steps S8 and S9 are repeated until the transfer of all data of the system program is completed.

  After all the data of the system program is transferred and the development of the system program on the RAM 15 is completed, the CPU unit 10 activates the system program (step S10). When the system program is activated, the mobile phone terminal 1 can be used by the user.

  After the completion of starting the system program, an application program (hereinafter referred to as an application) is downloaded.

  Prior to downloading the application, the CPU unit 10 reads the activation history information for each application stored in the data area 22 of the flash ROM 11 (step S11).

  The CPU unit 10 extracts an application with a high activation frequency based on the read activation history information (step S12).

  The CPU unit 10 sends a download request for the extracted application to the server 300 (step S13).

  The server 300 that has received the application download request transmits the application to the mobile phone terminal 1 in response to the request (step S14).

  The CPU unit 10 expands the received application data in the RAM 15 (step S15). The application data is appropriately divided by the server 300 according to the capacity and transferred to the mobile phone terminal 1, and steps S14 and S15 are repeated until the transfer of all the application data is completed.

  After all the application data is transferred and the development of the application on the RAM 15 is completed, the CPU unit 10 starts the application (step S16). As a result, the application function of the mobile phone terminal 1 can be used by the user. Note that, when another application is also activated, steps S13 to S16 are executed for each application.

  After the application is activated, the CPU unit 10 updates the activation history information for each application in the data area 22 of the flash ROM 11 (step S17).

  Here, the activation of the application when the cellular phone terminal 1 is activated based on the activation history information has been described. However, as described above, the activation time for each application is recorded in the activation history information. For this reason, when activation of a specific application is concentrated at a specific time, the application may be activated in advance before the activation time is reached. In such a case, steps S13 to S16 are executed in advance for the application before the activation time is reached. Such a configuration leads to an improvement in user convenience.

  Through the above procedure, the mobile phone terminal 1 as an example of the first embodiment can be used.

  FIG. 3 is a flowchart showing an application activation operation in accordance with a user instruction in the mobile phone system as an example of the first embodiment of the present invention.

  With reference to FIG. 3, the flow of processing in the mobile phone terminal 1 from when an application activation operation is performed by the user until the application function can be used will be described in detail.

  In the state where the activation of the system program and the application set to be automatically activated (the activation frequency is high) is completed, the user can use the operation unit 12 (not shown in FIG. 3) An activation instruction for an application (here, application A is taken as an example) is performed (step S20).

  In response to the application A activation instruction from the operation unit 12, the CPU unit 10 stores the activation history information of the application A in the data area 22 (not shown in FIG. 3) of the flash ROM 11 (step S21). In the activation history information, the number of activations for each application, the activation date and time, and the like are recorded.

  After saving the activation history information, the CPU unit 10 issues a read request for the app A to the server 300 (step S22).

  In response to the read request, the server 300 transmits the read permission of the application A to the mobile phone terminal 1 (step S23).

  The CPU unit 10 that has received permission to read the app A starts to download the app A (step S24).

  The CPU unit 10 issues a download request for the application A to the server 300 (step S25).

  The server 300 that has received the download request for the app A transmits the data of the app A to the mobile phone terminal 1 in response to the request (step S26).

  The CPU unit 10 expands the received application A data in the RAM 15 (step S27). The data of the app A is appropriately divided by the server 300 according to the capacity and transferred to the mobile phone terminal 1, and steps S26 and S27 are repeated until the transfer of all the data of the app is completed.

  After all the data of the application A is transferred and the development of the application A on the RAM 15 is completed, the CPU unit 10 activates the application A (step S28). As a result, the user can use the function of the application A of the mobile phone terminal 1. When another application is also activated, steps S20 to S28 are executed for each application.

  With the above procedure, the user's desired function can be used in the mobile phone terminal 1 which is an example of the first embodiment.

  The cellular phone system according to the present embodiment described above has an effect of reducing the manufacturing cost by reducing the flash ROM from the cellular phone terminal by downloading the system and application programs from a server on the Internet.

  In addition, since the mobile phone system according to the present embodiment executes a program developed on the RAM other than the boot program executed directly on the flash ROM, for example, a high-speed static RAM, a dynamic RAM, and the like are stored in the main memory. By being used as the RAM of the apparatus, it has the effect of speeding up the program processing time.

  In addition, the mobile phone system according to the present embodiment improves the convenience and reliability of the user and the system because the entire program of the mobile phone terminal is updated by replacing all the programs on the server instead of as differences. Has the effect of

  The mobile phone system according to the present embodiment suppresses the capacity of the system program as much as possible, and limits the programs that need to be downloaded at the time of activation based on the application activation history information. Therefore, the mobile phone system according to the present embodiment reduces the transfer load while using wireless communication with restrictions on data communication compared to a high-speed and large-capacity data communication environment such as wired broadband. Thus, since the mobile phone terminal is activated without extending the required time, there is an effect that the utility is high.

(Second Embodiment)
Hereinafter, a mobile phone system and a control method of the mobile phone system according to a second embodiment of the present invention will be described in detail with reference to the accompanying drawings.

  First, the configuration of the mobile phone system according to the second embodiment of the present invention will be described in detail.

  FIG. 4 is a functional block diagram showing a configuration of a mobile phone system as an example of the second embodiment of the present invention. Referring to FIG. 4, the mobile phone system according to this embodiment includes a mobile phone terminal 1, a base station 100, a gateway 200, and a server 300, as in the first embodiment described above. Communication between the mobile phone terminal 1 and the base station 100 is performed wirelessly. The base station 100 and the gateway 200 are connected by a telephone network, and the gateway 200 and the server 300 are connected by an Internet network.

  The mobile phone terminal 1 includes a CPU unit 10, a flash ROM 11, an operation unit 12, a wireless unit 13, and a RAM 15, as in the first embodiment described above. Since these and the detailed configuration and operation on the server 300 side are the same as those in the first embodiment described above, a description thereof will be omitted.

  In addition to the configuration described above, the mobile phone terminal 1 according to the present embodiment further includes a rewritable and nonvolatile auxiliary storage device 20 exemplified by a memory card such as an SD memory card. The auxiliary storage device 20 is detachably attached to the mobile phone terminal 1. The auxiliary storage device 20 is connected to the CPU unit 10 via an internal bus (not shown) as with each unit in the mobile phone terminal 1 in the first embodiment, and the CPU unit 10 controls the auxiliary storage device 20. Can do. The auxiliary storage device 20 has a feature that it is cheaper and has a larger capacity than the flash ROM 11.

  The auxiliary storage device 20 stores system programs and applications downloaded from the server 300 when the auxiliary storage device 20 is activated.

  Next, the operation of the mobile phone system according to the second embodiment of the present invention will be described in detail.

  FIG. 5 is a flowchart showing an operation until the mobile phone system as an example of the second embodiment of the present invention becomes available.

  With reference to FIG. 5, the flow of processing in the cellular phone terminal 1 from when the power is turned on until when the function can be used by executing the application program will be described in detail.

  First, after the mobile phone terminal 1 is turned on, for example, to reset the entire apparatus, the reset is released (step S101). As a result, the CPU 10, flash ROM 11, RAM 15, auxiliary storage device 20, operation unit 12, radio unit 13, and antenna 14 not shown in FIG. 5 are initialized in the mobile phone terminal 1. Is ready to operate.

  After the reset is released, the CPU unit 10 reads a boot program for starting the cellular phone terminal 1 (step S102). More specifically, the CPU unit 10 reads the boot program stored in the program area 21 (not shown in FIG. 5) of the flash ROM 11 built in the mobile phone terminal 1.

  The read boot program is directly executed and started by the CPU unit 10 (step S103). This boot program is the minimum for reading the system program of the cellular phone terminal 1 from the auxiliary storage device 20 and downloading it from the server 300 (not shown in FIG. 5) when there is no system program in the auxiliary storage device 20. It has limited functions. Therefore, at this stage, the mobile phone terminal 1 is not yet ready for use by the user.

  After starting the boot program, the CPU unit 10 reads the system program (step S104). More specifically, the CPU unit 10 reads a system program stored in the auxiliary storage device 20 built in the mobile phone terminal 1.

  The CPU unit 10 expands system program data from the auxiliary storage device 20 to the RAM 15 (step S105).

  Here, when the system unit cannot be read because the system program is not stored in the auxiliary storage device 20 or the like, the system program is read from the server 300 and expanded in the RAM 15. That is, when the system program cannot be read from the auxiliary storage device 20, steps S4 to S9 of the first embodiment are executed.

  In this way, after the development of the system program on the RAM 15 is completed, the CPU unit 10 activates the system program (step S106). When the system program is activated, the mobile phone terminal 1 can be used by the user.

  Note that, when the system program stored in the auxiliary storage device 20 cannot be started, the system program may be newly downloaded from the server 300. The newly downloaded system program is stored in the auxiliary storage device 20 and used at the next startup.

  After the start of the system program is completed, the application is started.

  Prior to application activation, the CPU unit 10 reads activation history information for each application stored in the data area 22 (not shown in FIG. 5) of the flash ROM 11 (step S107).

  The CPU unit 10 extracts an application with a high activation frequency based on the read activation history information (step S108).

  The CPU unit 10 reads out the extracted application with high activation frequency (step S109). More specifically, the CPU unit 10 reads an application stored in the auxiliary storage device 20 built in the mobile phone terminal 1.

  The CPU unit 10 expands application data from the auxiliary storage device 20 to the RAM 15 (step S110).

  If the application is not stored in the auxiliary storage device 20 and the CPU unit 10 cannot read the application, the application is read from the server 300 and expanded in the RAM 15. That is, when the application cannot be read from the auxiliary storage device 20, steps S13 to S15 of the first embodiment are executed.

  In this way, after the application development on the RAM 15 is completed, the CPU unit 10 activates the application (step S111). As a result, the application function of the mobile phone terminal 1 can be used by the user. When another application is also activated, steps S109 to S111 are executed for each application.

  Similar to the system program described above, when the application stored in the auxiliary storage device 20 cannot be activated, the application may be newly downloaded from the server 300. The newly downloaded application is stored in the auxiliary storage device 20 and used at the next and subsequent activations.

  After the application is activated, the CPU unit 10 updates the activation history information for each application in the data area 22 of the flash ROM 11 (step S112).

  In the present embodiment, as in the first embodiment, when the activation of a specific application is concentrated at a specific time, the application may be activated in advance before the activation time is reached. good. Such a configuration leads to an improvement in user convenience.

  Through the above procedure, the mobile phone terminal 1 as an example of the second embodiment can be used.

  FIG. 6 is a flowchart showing an application activation operation in accordance with a user instruction in the mobile phone system as an example of the second embodiment of the present invention.

  With reference to FIG. 6, the flow of processing in the mobile phone terminal 1 from when the user performs an application activation operation until when the application function can be used will be described in detail.

  In the state where the activation of the system program and the application set to be automatically activated (the activation frequency is high) is completed, the user can use the operation unit 12 (not shown in FIG. 6) An activation instruction of an application (here, application A is taken as an example) is performed (step S120).

  In response to the application A activation instruction from the operation unit 12, the CPU unit 10 stores the activation history information of the application A in the data area 22 (not shown in FIG. 6) of the flash ROM 11 (step S121). In the activation history information, the number of activations for each application, the activation date and time, and the like are recorded.

  After saving the activation history information, the CPU unit 10 reads the application A (step S122). More specifically, the CPU unit 10 reads the application A stored in the auxiliary storage device 20 built in the mobile phone terminal 1.

  The CPU unit 10 expands the data of the application A from the auxiliary storage device 20 to the RAM 15 (step S123).

  Here, if the application A is not stored in the auxiliary storage device 20 and the CPU unit 10 cannot read the application A, the application A is retrieved from the server 300 (not shown in FIG. 6). Read out and expand in RAM 15. That is, when the application A cannot be read from the auxiliary storage device 20, steps S22 to S27 of the first embodiment are executed.

  Thus, after the development of the application A on the RAM 15 is completed, the CPU unit 10 activates the application A (step S124). As a result, the user can use the function of the application A of the mobile phone terminal 1. When another application is also activated, steps S120 to S124 are executed for each application.

  Note that, similarly to the above-described startup program, the application A may be newly downloaded from the server 300 when the application A stored in the auxiliary storage device 20 cannot be started. The newly downloaded application A is stored in the auxiliary storage device 20 and used at the next and subsequent activations.

  In the present embodiment, the system program and various applications are updated at predetermined intervals by periodic download from the server 300 regardless of whether the system program and various applications in the mobile phone terminal 1 can be activated. It is also good. Further, such downloading for program update may be performed not under the activation of the cellular phone terminal 1 but under a low CPU and communication load.

  With the above procedure, the user's desired function can be used in the mobile phone terminal 1 which is an example of the second embodiment.

  The second embodiment described above has an effect equivalent to that of the first embodiment described above. That is, the cellular phone system according to the present embodiment has an effect of reducing the manufacturing cost by reducing the flash ROM from the cellular phone terminal by storing the system and the application program in a cheaper and large-capacity auxiliary storage device. Have.

  In addition, since the mobile phone system according to the present embodiment executes a program developed on the RAM other than the boot program executed directly on the flash ROM, for example, a high-speed static RAM, a dynamic RAM, and the like are stored in the main memory. By being used as the RAM of the apparatus, it has the effect of speeding up the program processing time.

  In addition, since the mobile phone system according to the present embodiment updates the program of the mobile phone terminal by replacing the program on the server as a difference rather than as a difference and periodically updating it, the user, And the convenience and reliability of the system are improved.

  The cellular phone system according to the present embodiment can suppress the capacity of the system program as much as possible, limit the programs that need to be activated based on the application activation history information, and selectively when the programs cannot be activated. In addition, the transfer load is reduced by downloading from the server, and the mobile phone terminal is activated without extending the required time, so that the practicality is high.

  The embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.
