  According to the technique of Patent Document 1, it is described that the update program storage means copies the already read update program to the main storage memory or the like when the system of the personal computer is started. I did not mention how to deal with this.

  In the case of a mobile terminal such as a car navigation system, the mobile terminal may be frequently turned on and off in a short time in accordance with the operation status of the vehicle, as compared with an information processing apparatus such as a personal computer. For this reason, in a mobile terminal that is frequently used in a short time, there is a problem that power supply is frequently cut off even during software installation, and the software installation process is not completed.

  In addition, in the case of a mobile terminal such as a car navigation system, a program with much interdependence related to map information or the like is frequently updated, so that power supply to the mobile terminal is not possible during the replacement of a plurality of programs that are interdependent / shared. If the program is stopped, or if a part of the replacement target program is activated, there is a problem that the software installation process cannot be completed.

  The present invention is an invention for solving the above-described problem, and in a mobile terminal that is frequently used in a short time, it can cope with disconnection of power supply and can proceed with the installation process step by step. An object is to provide a mobile terminal and a software update method.

In order to solve the above-described problem, a mobile terminal can install a plurality of interdependent program groups in stages even in a short activation time by performing the following steps.
(1) Holds a plurality of storage areas for data (program, DB (Data Base), registry information) necessary for program execution, and installs a group of programs in one storage area A. Use data to run programs.
(2) When the completion of the installation processing of the program group in the storage area A is detected when the system is stopped, the storage area referred to at the next activation is switched from B to A. On the other hand, when the completion of the installation process is not detected, the storage area to be referred to at the next activation is not changed when the system is stopped, and the completion stage of the installation process of the program group is recorded.

  According to the present invention, in a mobile terminal that is frequently used in a short time, it is possible to cope with the disconnection of the power supply and to proceed with the installation process step by step to update the software.

  The runtime data storage area storage unit 12 holds a plurality of logically divided storage areas 121 (120) and 122 (120). The storage area 121 (first storage area) that is the storage area A and the storage area 122 (second storage area) that is the storage area B are the runtime data (program, shared data, System setting information) is stored. The mobile terminal 1 makes it possible to select and refer to a single storage area or a plurality of storage areas from the storage areas 121 and 122 when the mobile terminal 1 is activated.

  FIG. 3 is an explanatory diagram showing the runtime data storage area reference point information. FIG. 3 shows a data structure of the runtime data storage area reference point information 90 (reference point information of the runtime data storage area) of the runtime data storage area reference point storage unit 11. In the present embodiment, the runtime data storage area reference point information 90 is stored in the storage device 50, but may be stored in a non-volatile memory included in the power management IC 60 or the like.

  The runtime data storage area reference point information 90 is information to be referred to when the mobile terminal 1 is activated, and logical storage areas corresponding to the storage areas 121 and 122 are defined. In the runtime data storage area reference point information 90, a data storage area and a logical storage area identifier referred to by the mobile terminal 1 during startup are described in association with each other (reference numeral 91), and the storage areas 121 and 122 and the logical storage are stored. The area identifier can be logically hierarchized to describe a plurality of associations (reference numeral 93).

  The runtime data storage area reference point information 90 describes a plurality of runtime data storage areas in a logical hierarchy, and the CPU 20 (processing device) is in each hierarchy referenced when the mobile terminal 1 is activated. Switch the reference point for data storage area at runtime. The runtime data storage area reference point can be switched by the symbol #.

  The symbol “#” shown in FIG. 3 is a comment-out, and when the software setting file is partially modified, the contents to be erased are not actually erased. That means Specifically, in the case of reference numeral 91, the storage area A side is referred to when the system is started. In addition, when the runtime data storage area reference point of the storage area 120 is changed, the symbol “#” is added to the line on the storage area A side and deleted from the line on the storage area B side.

  The runtime data storage area reference point storage unit 11 can be rewritten by processing executed by the installation processing unit 53 or the runtime data storage area management unit 52 while the mobile terminal 1 is operating. The mobile terminal 1 refers to the runtime data storage area reference point storage unit 11 at the time of activation, and recognizes the runtime data storage area storage unit 12 that the mobile terminal 1 refers to during operation.

  FIG. 4 is an explanatory diagram showing installation program attribute information. FIG. 4 shows the data format of the attribute information description of the install program attribute information 160 (install program attribute information) stored in the install program attribute information storage unit 15. The attribute information description includes, for example, an installation program acquired by the mobile terminal 1 from the center terminal 3 or from the center terminal 3 (see FIG. 2) connected via the wired communication interface 22 or the I / O interface 23. It is distributed as an installer. The attribute information description is defined for each program. Each program is associated with the data item “program name” (161) of the installation program attribute information 160 of the attribute information description.

  The installed program attribute information 160 includes a program name (161), a distribution unit (package) name (162), a content type (163), an update unit number (program number) (164), a size (165), a dependency package / shared. A data identifier (166) is included. The content type includes an application (application software), middleware commonly used by a plurality of application software, firmware that is software for controlling hardware incorporated in the mobile terminal 1, and the like. The capacity of the update unit is desirably small so that the mobile terminal 1 can be installed even if it is operated for a short time. In the case of the specific example shown in FIG. 4, it can be seen from the number of update units (164) that the number of programs is 14, and the total capacity is 12 Mbytes.

  The installation processing unit 53 (see FIG. 2) identifies to which distribution unit (package) each program belongs by the data item “distribution unit (package) name” (162) of the installation program attribute information 160. The programs included in the distribution unit (package) may be interdependent / shared.

  The install processing unit 53 refers to the data item “dependent package / shared data identifier” (166) of the install program attribute information 160 to identify the package / shared data to which the package to which the program belongs depends. The installation order of the packages stored in the installation program storage unit 16 is determined. Preferentially install packages that depend on each package. Further, the installation processing unit 53 determines whether or not the program requires immediate updating based on the data item “content type” (163).

(Reference point switching function)
FIG. 5 is an explanatory diagram of a runtime data storage area according to the process flow of the install / copy process. Reference is made to FIG. 2 as appropriate. The main subject of the processing is the CPU 20, but will be described as an installation processing unit 53 that is a program. The installation processing unit 53 installs / copys a program or the like in the runtime data storage area storage unit 12 and executes runtime data storage area reference point information 90 according to the state of the installation / copy process (state 1 to state 4). Has a reference point switching function for performing the switching process. In FIG. 5, the symbol * means a reference point at start-up that is a reference point at run-time data storage area of the run-time data storage area storage unit 12 referenced in each state.

  Specifically, when the installation process to the storage area A in the state 1 is being performed in step S111, the storage area B is a reference point at startup, and the installation process to the storage area A in the state 2 is completed in step S113. In this case, the storage area A becomes a reference point at the time of activation. In step S115, when the copy process from the storage area A in the state 3 to the storage area B is in progress, the storage area A becomes a reference point at the time of activation. Furthermore, when the copy process from the storage area A in the state 4 to the storage area B is completed in step S117, the storage area B becomes a reference point at the time of activation. The startup reference point is a reference point of execution data when the mobile terminal 1 is powered off and restarted. Specifically, the runtime data storage area storage unit 12 (storage area A (121) or storage area B (122)) is referred to.

  In the case of installation processing, the installation processing unit 53 manages the update unit of the update program group 105 as a distribution unit (package). In FIG. 5, the state 1 (step S111) and the state 2 (step S113) schematically show the installation processing stage for the storage area A / storage area B. The hatched portion in the figure indicates that the installation process for the update unit has been completed.

The correspondence between the installation process executed by the installation processing unit 53 and the description content of the runtime data storage area reference point storage unit 11 will be described below.
State 1: When the installation processing unit 53 is performing an installation process on the storage area A, the runtime data storage area reference point is associated with the storage area B, and the newly installed data is stored in the mobile terminal 1. It does not affect the operation (step S111).

  State 2: When the installation for the storage area A is completed, the installation processing unit 53 notifies the runtime data storage area management unit 52 of the installation completion event, and the runtime data storage area management unit 52 that has received the notification The execution data storage area reference point is associated with the storage area A. At this stage, the mobile terminal 1 is operating with reference to the storage area B (step S113).

  State 3: The mobile terminal 1 operates with reference to the storage area A. Further, the installation processing unit 53 copies the data already installed in step S113 during the operation from the storage area A to the storage area B. At this time, the data to be copied is specified by referring to the installation history of the data installed in step S111 (step S115).

  State 4: When the installation processing unit 53 detects an end event of the copy process in step S115 from the storage area A to the storage area B, the installation processing unit 53 notifies the execution data storage area management unit 52 of the end event and executes it. The time data storage area management unit 52 associates the execution time data storage area reference point with the storage area B (step S117).

(Registration processing in the runtime data storage area reference point storage unit)
FIG. 6 is a flowchart showing the registration process of the reference point at start-up to the runtime data storage area reference point storage unit. FIG. 6 shows a flow of processing for registering the reference point at startup in the runtime data storage area management unit 52 in the runtime data storage area reference point storage unit 11.

  When the runtime data storage area management unit 52 receives the power-off event notification message from the system state management unit 51 (step S71), the execution time data storage area management unit 52 depends on the storage area A (the system non-reference area in state 1 shown in FIG. 5). It is determined whether or not a plurality of programs sharing data are being installed (step S72). If the runtime data storage area management unit 52 is in the middle of installation in the storage area A (Yes in step S72), the runtime data storage area management unit 52 uses the storage area B (the system in the state 1 in FIG. 5) as the runtime data storage area at the next system startup. The reference area or the system reference area in state 4) is selected and registered in the runtime data storage area reference point storage unit 11 (step S74).

  In step S72, if a plurality of programs interdependent / data sharing in the storage area A is not being installed (when the installation process is completed) (No in step S72), the runtime data storage area management unit 52 Whether or not a plurality of programs already installed in A (system reference reference area in state 2 or state 3 in FIG. 5) has been copied to storage area B (system non-reference area in state 2 or state 3 in FIG. 5). Determination is made (step S73). If it has not been copied (No at Step S73), the runtime data storage area management unit 52 uses the storage area A (referring to the system in state 2 or state 3 in FIG. 5) as the runtime data storage area at the next system startup. Area) is selected and registered in the runtime data storage area reference point storage unit 11 (step S75).

  If a plurality of programs already installed in the storage area A have been copied to the storage area B in step S73 (step S73, Yes), the process proceeds to step S74.

  When installation / copy processing is interrupted at each step, the installation processing unit 53 records the name of the package being processed and the name of the program for which the processing has been completed in the installation stage storage unit 13, and the next processing is performed. At the start, programs other than the program that has been processed are processed.

  In step S71, the power-off event is described as a system stop, but the present invention is not limited to this. For example, an operation command from the input / output device 24 may be received, and the processes after step S72 may be performed.

(Installation processing function considering processing load)
Next, an installation processing function that considers the processing load in the installation processing unit 53 (start / continue installation / copy processing in consideration of the processing load) at the start of the installation processing and copy processing in each step and during the processing Will be described.

  The installation processing unit 53 acquires the name of the program being operated in the mobile terminal 1, the processing load index of the mobile terminal, and the mobile terminal conditions from the system state management unit 51, and the installation / copy processing start condition information 400 shown in FIG. refer.

  FIG. 7 is an explanatory diagram showing installation / copy process start condition information. The installation / copy process start condition information 400 is stored in the install / copy process start condition storage unit 14. The installation / copy process start condition information 400 includes a program name 401, a mobile terminal processing load index 402, and a mobile terminal condition 403 (mobile terminal installation condition). In the present embodiment, the installation / copy process is started when the condition shown in FIG. 7 is not satisfied at the start of the installation / copy process.

  Specifically, when the emergency communication program is operating and the CPU usage rate is larger than 40% and the memory usage amount is larger than 128 MB, this means that installation / copy processing is not executed. . That is, priority is given to emergency communication in the mobile terminal 1. Similarly, when the navigation program is operating, if the CPU usage rate is greater than 50% and the memory usage amount is greater than 128 MB during movement (running), the installation / copy process is not executed. Means that. That is, the navigation program in the mobile terminal 1 is prioritized.

  Returning to the installation process in consideration of the processing load, the installation processing unit 53 refers to the installation / copy process start condition information 400 shown in FIG. 7, and the acquired program name 401 is operating, and the mobile terminal If the processing load index 402 and the mobile terminal condition 403 satisfy the conditions, the installation / copy process may not be started or the installation / copy process may be interrupted.

  According to the present embodiment, in the mobile terminal 1 that is activated / stopped in a short time, the installation process can be advanced step by step in the installation process of a plurality of interdependence / data sharing program groups (packages). Further, in the installation process, the mobile terminal 1 can be implemented in a form that does not hinder the operation of the program that runs on the mobile terminal 1.

(Installation order control function)
FIG. 8 is a flowchart showing the installation order control process. When installing a plurality of programs that are mutually dependent / shared with data, the installation processing unit 53 refers to the priority / program type correspondence information 300 (priority / content type correspondence information) shown in FIG. It has an installation order control function that allows programs to be installed first.

  The installation processing unit 53 starts to install a program group (package) for interdependency / data sharing stored in the installation program storage unit 16 (step S81). The installation processing unit 53 periodically refers to the installation program attribute information storage unit 15 and the installation program storage unit 16 during the installation process, and install program attribute information corresponding to a program / program group stored in the installation program storage unit 16. Referring to the data item “content type” 163 (see FIG. 4) and the priority / program type correspondence information 300 shown in FIG. 9, the priority of the program group is determined, and the currently installed program group It is determined whether or not a program group / program having higher priority than (package) is stored in the installation program storage unit 16 (step S82).

  When the installation processing unit 53 detects that a high priority program group / program exists in the installation program storage unit 16 (Yes in step S82), that is, a higher priority than the program group currently being installed. When it is necessary to install the program group / program, the installation process of the interdependency / data sharing program group being processed is stopped (step S83), and the program group / program is selected according to the priority of the installation program attribute information 160 Then, it is installed in the storage area 120, which is a system non-reference area (step S84), and the process returns to step S82. The program group / program installed here depends only on data that has already been installed.

  If there is no program group / program with higher priority than the currently installed program group (package) in the installation program storage unit 16 (No in step S82), the installation processing unit 53 determines that a single program is included in the program group. Is installed in the storage area 120 of the system non-reference area (step S85), and it is determined whether or not the installation of a plurality of program groups for interdependency / data sharing is completed (step S86).

  If the installation of a plurality of program groups that are interdependent / data sharing is incomplete (step S86, No), the process returns to step S82. If the installation of a plurality of program groups that are interdependent / data sharing is complete (step S86, Yes), the process ends.

  FIG. 9 is an explanatory diagram showing priority / program type correspondence information. The priority / program type correspondence information 300 (priority / content type correspondence information) is stored in the installation / copy process start condition storage unit 14, and includes the priority and the program type (including the content type). Correspondence information is defined. Records 301 and 302 that start with priority 00 of priority / program type correspondence information 300 are programs that require immediate updating, and records 303 and 304 that start with 10 are programs that are interdependent / shared with data. Judged as a group (package).

  Specifically, the installation processing unit 53 of the mobile terminal 1 displays an installer including attribute information of the size of each program and the program type (map, POI (Points of Interest) information, application, etc.) in the center terminal 3 (see FIG. 2). ) And the like, and whether or not immediate updating is necessary is determined according to the attribute information. The installation processing unit 53 may directly install a program that requires immediate updating in the storage area 120 of the system reference middle area. Thereby, it is possible to reflect an immediate update program.

  According to the present embodiment, it is possible to determine whether or not each program can be immediately updated, and to make it possible to immediately update a program that requires immediate update. It is also possible to install programs that require immediate updating with priorities.

(Embodiment 2)
In the first embodiment, (1) the reference point switching function, (2) the installation processing function considering the processing load, and (3) the installation order control function have been described. In the second embodiment, the storage area 120 for each content type is described. An integrated program of the functions shown in (1) to (3) executed by the installation processing unit 53 will be described.

  Generally, software updates to the mobile terminal 1 include software from a plurality of vendors, and are therefore distributed from servers owned by the vendors at different timings. For this reason, the runtime data storage area storage unit 12 has a storage area 120 for each content type, so that it is possible to install / copy contents with priority.

  FIG. 10 is an explanatory diagram showing a runtime data storage area for each content type. The runtime data storage area storage unit 12 includes a “map” storage area 501, a “POI information” storage area 503, an “application” storage area 505, a “driver” storage area 507, and the like. The storage area 501 has a plurality of storage areas A1 and B1, the storage area 503 has a plurality of storage areas A2 and B2, the storage area 505 has a plurality of storage areas A3 and B3, and the storage area 507 has It has a plurality of storage areas A4, B4. Further, the mobile terminal 1 can switch reference points (areas marked with *) for the storage areas 501, 503, 505, and 507.

  By holding the storage area A and the storage area B for each content type, it is possible to perform installation / copy processing of prioritized content. The installation / copy processing of programs belonging to the respective content types in the storage areas 501, 503, 505, and 507 may be interrupted by an interrupt request for starting the installation / copy processing of other content. It is possible to start the process from the middle of the next installation / copy process while maintaining the progress of the installation / copy process that has been advanced step by step. By adopting this configuration, each content in the storage areas 501, 503, 505, and 507 can be distributed from different vendors / sites / servers at a desired timing.

  FIG. 11 is a flowchart showing installation / copy processing of a plurality of programs. The installation processing unit 53 determines whether or not the installation / copy processing start condition information 400 (see FIG. 7) is satisfied (step S91). If the installation / copy processing start condition information 400 is satisfied (step S91, Yes), the installation / copy processing is already in progress. It is determined whether or not the program (A) exists (step S92). If the program (A) exists, the installation processing unit 53 determines whether or not the program (A) is the same type program as the program (B) that newly requests installation / copy processing start (step S93). In the case of a similar program (step S93, Yes), the program (A) install / copy process is waited for, and the program (B) install / copy process is executed (step S94). Note that the program (A) and the program (B) in FIG. 11 collectively use a program group (package) / program, which means that they are different program groups / programs.

  In step S91, when the installation / copy process start condition is not satisfied (step S91, No), the process ends. If the program (A) does not exist in step S92 (No in step S92), the priority / program type correspondence information 300 is referred to, and the program having the highest priority is selected from the stored programs and installed. / Copy processing is executed (step S95), and the processing is terminated.

  In step S93, when the program (A) and the program (B) are not the same type of program (No in step S93), refer to the priority / program type correspondence information 300 for the priorities of the program (A) and the program (B). The high priority program installation / copy process is executed, the low priority program process is interrupted / waited (step S96), and the waiting program installation / copy process is executed (step S96). S97), the process is terminated.

  According to the mobile terminal 1 of the present embodiment, the mobile terminal 1 holds a plurality of storage areas for data (program, database storage information, registry information) necessary for program execution, and a storage area 121 (first storage area). Is in the middle of installing a plurality of programs that are interdependent / data sharing, the program group is operated using data in the storage area 122 (second storage area) different from the storage area 121 in the middle of installation. When the completion of the installation process is detected when the system is stopped, the storage area to be referred to at the next startup is switched to the storage area 121 that was the target of the installation process. On the other hand, when the completion of the installation process is not detected, the storage area 122 referred to at the next activation is not changed when the system is stopped, the completion stage of the installation process of the program group is recorded, and the installation process is continued at the next activation. . Accordingly, in the mobile terminal 1 that is frequently used in a short time, it is possible to cope with the disconnection of the power supply and to proceed with the installation process step by step.

  The mobile terminal 1 according to the present embodiment includes a CPU 20 (processing device) and a storage device 50, and is capable of acquiring a program that operates on the terminal via the communication interface (for example, the wireless communication device 21) via the communication interface. When the mobile terminal 1 is in operation, the terminal 1 can install a plurality of interdependent program groups associated with the program in stages to update the software.

  The storage device 50 includes a runtime data storage area storage unit having a first storage area 121 and a second storage area 122 as a runtime data storage area for storing a program group and data referred to by the program group in the mobile terminal 1. 12, an installation program storage unit 16 that stores an installation program necessary for updating the program group, an installation program attribute information storage unit 15 that stores the name of the program group as installation program attribute information 160, and activation of the mobile terminal 1 Runtime data storage area reference point storage unit 11 for storing runtime data storage area reference point information 90 at the time, and the second storage area is registered in advance as reference point information of the runtime data storage area .

  When the CPU 20 (processing device) receives the installation program and the attribute information of the installation program, the CPU 20 performs an installation process of the program group in the first storage area (step S111), and after the installation process is completed, the first storage area. When the stored program group is copied to the second storage area (step S115), the processing device determines whether or not the installation processing is in progress when receiving a notification of the power-off event.
