The mobile terminal 1 can receive the relay function and application program provided by the relay device 2 belonging to the relay device 2 only when the mobile terminal 1 is located in the service area 5.

  The server device 4 provides application services (groupware, word processing software, presentation, video conference, streaming playback, etc.) with the mobile terminal 1 as a client, and also provides the relay device 2 with an application program to be executed on the mobile terminal 1. To deliver.

  Next, details of the mobile terminal 1 and the relay device 2 that constitute the application providing system according to the present embodiment will be described.

  First, details of the mobile terminal 1 will be described.

  FIG. 2 is a schematic functional configuration diagram of the mobile terminal 1.

  As illustrated, the mobile terminal 1 includes a wireless interface unit 101, a short-range wireless interface unit 102, a user interface unit 103, a mobile terminal function unit 104, an application program storage unit 105, and an application program execution unit 106. , An area monitoring unit 107, an authentication unit 108, an application program management unit 109, an application program usage record management unit 110, an application program unused period storage unit 111, and an application program class storage unit 112. .

  The wireless interface unit 101 is an interface for connecting to a wireless base station (not shown) by wireless communication such as 3G or Wi-Fi.

  The short-range wireless interface unit 102 is an interface for belonging to the relay device 2 by short-range wireless communication such as Bluetooth (registered trademark).

  The user interface unit 103 includes an output device such as a display and a speaker, and an input device such as an operation panel. The user interface unit 103 outputs information such as a desktop screen to the output device and receives an operation from the operator via the input device.

  The mobile terminal function unit 104 is a processing unit that implements a function as a mobile terminal, and establishes a communication path with the counterpart device via the wireless interface unit 101. Then, the call data and text data of the communication partner received from the partner device via this communication path are output to the user interface unit 103, and the call data and text data of the operator received from the user interface unit 103 are The data is transmitted to the partner apparatus via this communication path.

  The application program storage unit 105 stores programs for various applications (groupware, word processing software, presentation, video conference, streaming playback, etc.) including application programs acquired from the relay apparatus 2 by the application program management unit 109 described later. The

  The application program execution unit 106 executes an application program stored in the application program storage unit 105 in accordance with an operator instruction received via the user interface unit 103 or an instruction from the application program management unit 109.

  The area monitoring unit 107 monitors whether or not the portable terminal 1 is located in the service area 5 of the relay device 2 based on the reception intensity of the radio wave signal (for example, beacon signal) transmitted from the relay device 2. As described above, since the service area 5 of the relay device 2 is set narrower than the communication area 6 of the relay device 2, the radio wave signal that is determined that the mobile terminal 1 is located in the service area 5. The threshold value of the reception intensity is higher than the threshold value of the reception intensity of the radio signal that is determined that the mobile terminal 1 is located in the communication area 6.

  When the area monitoring unit 107 detects that the mobile terminal 1 has moved from outside the service area 5 of the relay device 2 into the service area 5, the authentication unit 108 transmits an attribution request to the relay device 2. At the same time, ID and password set in advance in the portable terminal 1 are notified and authentication is performed. By receiving this authentication, the portable terminal 1 is permitted to transmit / receive information to / from the server device 4 and can receive provision of an application program stored in the relay device.

  The application program management unit 109 transmits a request for an application program list to the relay device 2 after the authentication unit 108 has successfully authenticated the relay device 2.

  Here, the application program list is a list showing all application programs stored in the relay apparatus 2, and shows the program name and version information.

  The reason why the version information is required is that programs having different versions are managed as different programs even if the applications have the same name. For example, the old version of the program is not used, but it is adapted to the case where the frequency of use increases because of the new version and enhanced functions and performance.

  Then, the application program management unit 109 refers to the application program class storage unit 112.

  Here, the application program class storage unit 112 will be described with reference to FIG.

  FIG. 3 is a diagram schematically showing the contents stored in the application program class storage unit 112. As shown in the drawing, the application program class storage unit 112 stores an application program name including version information in a record 1120. The record 1120 includes an online / offline class field 1121 that stores application program names that have been used online and offline with respect to the relay device 2, and an online class field 1122 that stores application program names that have been used only online. And an offline class field 1123 for storing application program names that have been used only offline, and an unused class field 1124 for storing application program names that have been determined to be unused.

  The application program management unit 109 collates the application program list received from the relay device 2 with the application program name stored in the application program class storage unit 112 (if the version information includes the version information), online A program that matches the one stored in the class field 1121 and a new program that does not match all the fields are selected from the application program list, and a download request including the selected application program name is sent to the relay device 2. Send to. Then, the application program is acquired from the relay device 2 and stored in the application program storage unit 105. The fact that version information is not stored in the unused class field 1124 indicates that the application program is not automatically downloaded, including version upgrades.

  The application program management unit 109 executes the application program stored in the online class field 1122 of the application program class storage unit 112 and is not executed in the application program stored in the online / offline class 1121. The application program execution unit 106 is instructed to execute the program.

  The application program usage record management unit 110 acquires the application program use record from the application program execution unit 106 and updates the application program unused period storage unit 111.

  Here, the usage record is not shown, but it is detected that the access to the application program from the user interface unit 103 (for example, input from the operation panel (character input or button operation) is input for the application program) ) Occurs, the application program execution unit 106 detects this, notifies the application program usage record management unit 110 of the use of the application program, and the application program use record management unit 110 receives the notification of the application program use. Then, this is stored, or the record corresponding to the application program is updated.

  In this embodiment, the access to the application program from the user interface unit 103 is stored and updated, but it may be stored and updated starting from the start of the application program.

  Here, the application program unused period storage unit 111 will be described with reference to FIG.

  FIG. 4 is a diagram schematically showing the storage contents of the application program unused period storage unit 111. As shown in the figure, the application program unused period storage unit 111 stores a record 1110 for each application program.

  A record 1110 includes an application program field 1111 for storing an application program name (including version information), an unused period field 1112 indicating a period in which the application program is unused, and subfields of an unused period field 1112. It has an online field 1123 indicating an online unused period and an offline field 1124 indicating an offline unused period.

  The application program usage record management unit 110 periodically adds an elapsed time to the unused period field 1112 corresponding to the unused application program (for example, every hour). The application program usage record management unit 110 clears the corresponding unused period field 1112 to 0 hour each time the use of the application program is detected. The application program usage record management unit 110 stores a character string indicating “excess” in the unused period field 1112 when an unused application program exceeds a predetermined period (for example, 10 days). Then, the application program class storage unit 112 is updated.

  Specifically, application programs that exceed only the online field 1123 are online classes, application programs that exceed only offline are offline classes, application programs that do not exceed both are online and offline classes, and application programs that exceed both are not used Each field of the application program class storage unit 112 is rewritten as a class.

  Next, details of the relay device 2 will be described. FIG. 5 is a schematic functional configuration diagram of the relay device 2.

  As illustrated, the relay device 2 includes a short-range wireless interface unit 201, a network interface unit 202, a relay unit 203, an authentication unit 204, an application program storage unit 205, an application program transmission unit 206, and an application program. A list transmission unit 207.

  The short-range wireless interface unit 201 is an interface for connecting to the mobile terminal 1 through short-range wireless communication such as Bluetooth (registered trademark).

  The network interface unit 202 is an interface for connecting to the network 3.

  The relay unit 203 relays information transmitted and received between the server device 4 and the portable terminal 1 via the short-range wireless interface unit 201 and the network interface unit 202 through permission of the authentication unit 204 described later. .

  In response to the attribution request including the ID and password from the mobile terminal 1, the authentication unit 204 checks the ID and password registered in the device in advance, and permits the attribution of the mobile terminal 1. The information relay processing for the portable terminal 1 is permitted.

  The application program storage unit 205 stores various application programs (groupware, word processor software, presentation software, video conference software, streaming playback software, etc.) that can be executed by the mobile terminal 1 acquired from the server device 4 or the like.

  The application program transmission unit 206 transmits the application program stored in the application program storage unit 205 according to the download request including the designation of the application program received from the mobile terminal 1 via the short-range wireless interface unit 201. It transmits to the portable terminal 1 via the interface unit 201.

  The application program list transmission unit 207 receives all application program names (including version information) stored in the application program storage unit 205 in accordance with the application program list request received from the mobile terminal 1 via the short-range wireless interface unit 201. Is sent to the portable terminal 1 via the short-range wireless interface unit 201.

  The application program transmission unit 206 and the application program list transmission unit 207 operate only on the mobile terminal 1 authenticated by the authentication unit 204.

  FIG. 6 is a sequence diagram for explaining an operation example when the mobile terminal 1 moves from outside the service area 5 of the relay device 2 into the service area 5 in the application providing system according to the present embodiment.

  First, when the mobile terminal 1 detects that it has moved into the service area 5 of the relay device 2 (S100), it transmits an attribution request including the ID and password of the mobile terminal to the relay device 2 (S101). In response to this, the relay device 2 sends an attribution response (permission) to the portable terminal 1 because the received ID and password of the portable terminal 1 match the ID and password registered in advance in the own device and match ( S102).

  Next, the portable terminal 1 transmits an application program list request to the relay device 2 (S103). In response, the relay device 2 transmits an application program list (S104). Then, the mobile terminal 1 selects an application program to be downloaded from the application program list (S105), and transmits a download request including the designation to the relay device 2 (S106). Receiving this, the relay apparatus 2 transmits the designated application program (S107).

  Next, the portable terminal 1 stores the received application program (S108). Among the stored applications, a new application is added to the online / offline class field 1121 of the application program class storage unit 112 and added to the application program field 1111 of the application program unused period storage unit 111 to start counting the unused period. (S109). Next, the online class and online / offline class application programs are executed (S110).

  Thereafter, the relay device 2 relays information exchange between the mobile terminal 1 and the server 4 (S111).

  FIG. 7 is a sequence diagram for explaining an operation example when the mobile terminal 1 moves from the service area 5 of the relay device 2 to the outside of the service area 5 in the application providing system according to the present embodiment.

  In a state where the mobile terminal 1 belongs to the relay device 2 and the relay between the mobile terminal 1 and the server device 4 is established (S200), the mobile terminal 1 has moved outside the service area 5 of the relay device 2 When this is detected (S201), an attribution cancellation request is transmitted to the relay device 2 (S202). Receiving this, the relay apparatus 2 performs an attribution cancellation process and transmits an attribution cancellation response to the mobile terminal 1 (S203).

  Next, the mobile terminal 1 ends the online class application program (S204) and deletes the application program (S205).

  Further, the relay device 2 ends the relay process for the mobile terminal 1 (S206).

  FIG. 8 is a flowchart for explaining the operation of updating the usage record of the application program of the mobile terminal 1.

  This flow is started after the portable terminal 1 is activated by turning on the power.

  First, the application program usage record management unit 110 determines whether or not a predetermined time or more has passed since the last periodic update (S300), or whether or not a notification of application program use has been notified from the application program execution unit 106 (S301). judge.

  When a predetermined time or more has elapsed since the last periodic update (YES in S300), the application program usage record management unit 110 selects one record that has not been updated this time in the record 1110 of the application program unused period storage unit 111. (S302), the elapsed time from the previous update time is added to the field 1112 (both subfields 1123 and 1124) and stored (S303). The interval of the regular update is, for example, 1 hour, but when the mobile terminal 1 is turned off, the elapsed time is calculated and added by the clock function.

  In addition, the application program usage record management unit 110, as a result of the processing in S303, results in an unused period (for example, 10 days) predetermined in any of the subfields 1123 and 1124 of the field 1112 of the application program unused period storage unit 111. Whether or not there is an excess is determined (S304). When the predetermined unused period is exceeded (YES in S304), the application program usage record management unit 110 stores a character string indicating excess in the target field (1123 or 1124) (S305), and proceeds to S306. . On the other hand, the application program usage record management unit 110 proceeds to S306 without doing anything when a predetermined unused period has not been exceeded (NO in S304).

  Next, the application program usage record management unit 110 refers to the record 1110 and the field 1112 (both subfields 1123 and 1124) in the updated application program unused period storage unit 111, and determines whether there is a character string indicating excess. The application program is classified (S306). If the application program usage record management unit 110 indicates that only the online unused period has been exceeded in step 306, the application program usage record management unit 110 classifies the target application program as an offline class program and stores the application program class storage unit 112 in the field 1123. The application program name (including version information) is stored (S307).

  If the application program usage record management unit 110 indicates that only the unused period in the offline state has been exceeded in step 306, the application program usage record management unit 110 classifies the target application program as an online class program and stores the application program class storage unit 112 in the field 1122. The application program name (including version information) is stored (S308).

  If the unused period of both online and offline indicates an excess in step 306, the application program usage record management unit 110 classifies the target application program as a program of an unused class and the application program storage unit 105 The application program is deleted (S309). Then, the application program usage record management unit 110 stores the application program name in the field 1124 of the application program class storage unit 112 (S310).

  In step 306, the application program usage record management unit 110 classifies the target application program as an online / offline class program when both the online and offline unused periods do not indicate an excess, and the application program class storage unit 112 The application program name (including version information) is stored in the field 1121 (S311).

  Next, the application program usage record management unit 110 determines whether there is a record that has not been updated this time in the record 1110 of the application program unused period storage unit 111 (S312). If there is a record that has not been updated this time (NO in S312), the process returns to S302 to continue the update process. If there is no record not updated this time (YES in S312), the application program usage record management unit 110 returns to S300 and waits for the next update opportunity.

  On the other hand, when the application program usage record management unit 110 receives an event notification of the use of the application program from the application program execution unit 106 (YES in S301), it identifies the corresponding application program (S313) and is it currently online? It is specified whether it is offline (S314). Then, the application program usage record management unit 110 refers to the application program unused period storage unit 111 (S315), searches the record 1110 in which the application program name specified in the field 1111 is stored, and uses the unused period field. The online field 1123 (in the case of the current online) or the offline field 1124 (in the case of the current offline) which is a subfield of 1112 is cleared to 0 hour (S316). Then, the process returns to S300 and waits for the next update opportunity.

  FIG. 9 is a flowchart for explaining the operation when the mobile terminal 1 moves into the service area 5 of the relay device 2 or moves out of the service area.

  This flow is started after the portable terminal 1 is activated by turning on the power.

  First, the area monitoring unit 107 moves the mobile terminal 1 from outside the service area 5 of the relay device 2 into the service area 5 (S400), or from the service area 5 of the relay device 2 to outside the service area 5. (S410) is detected. If the mobile terminal 1 detects a movement of the relay device 2 from outside the service area 5 into the service area 5 (YES in S400), the area monitoring unit 107 instructs the authentication unit 108 to execute attribution processing.

  Upon receiving the instruction, the authentication unit 108 transmits an attribution request including an ID and password registered in advance to the portable terminal 1 to the relay device 2 and receives an attribution response (permission) from the relay device 2 (S401). Then, the authentication unit 108 notifies the application program management unit 109 that the attribution to the relay device 2 has been completed. Although not shown, when attribution is not permitted, a character string indicating that attribution is not possible, an ID and password input screen are displayed on the display via the user interface unit 103, and user input is detected. Then, the attribution process is executed again.

  Next, the application program management unit 109 transmits a request for an application program list to the relay device 2 (S402). When the application program management unit 109 receives the application program list from the relay device 2 (YES in S403), the application program management unit 109 refers to the application program class storage unit 112. Then, by removing the programs stored in the online / offline class field 1121, the offline class field 1123, and the unused class field 1124 of the application program class storage unit 112 from the application program list, the application downloaded from the relay device 2 A program is selected (S404). The online / offline class and offline class application programs correspond to programs stored in the portable terminal 1.

  Next, the application program management unit 109 transmits a download request including the application program name selected in S404 to the relay apparatus 2 (S405). When the application program management unit 109 receives the application program from the relay device 2 (YES in S406), the application program management unit 109 stores the received application program in the application program storage unit 105 (S407) and registers it in the application program class storage unit 112. The new application program name that has not been saved is stored in the online / offline online / offline class field 1121. Further, the application program class storage unit 112 adds the record 1110 of the application program unused period storage unit 111, stores the new application program name in the application program field 1111, and sets the unused period field 1112 to the initial value (0 hours). ) (S408). Thereby, the count is started by the processing of FIG.

  Next, the application program management unit 109 refers to the application program class storage unit 112 and compares the application program stored in the online class field 1122 and the application program stored in the online / offline online / offline class field 1121. The application program execution unit 106 is instructed to execute an unexecuted program.

  Upon receiving the instruction, the application program execution unit 106 extracts and executes the designated program from the application program storage unit 105 (S409). Then, the area monitoring unit 107 returns to S400 and detects the next movement.

  On the other hand, when the own mobile terminal 1 detects the movement of the relay device 2 from the service area 5 to the outside of the service area 5 (YES in S410), the area monitoring unit 107 instructs the authentication unit 108 to execute the attribution cancellation process. To do.

  Upon receiving the instruction, the authentication unit 108 transmits an attribution cancellation request to the relay device 2 and receives an attribution cancellation response from the relay device 2 (S411). Then, the authentication unit 108 notifies the application program management unit 109 that the attribution cancellation from the relay device 2 has been completed.

  Next, the application program management unit 109 instructs the application program execution unit 106 to end the online class application program. Receiving this, the application program execution unit 106 terminates the online class application program (S412).

  Also, the application program management unit 109 deletes the online class application program from the application storage unit 105 (S413). Then, the area monitoring unit 107 returns to S400 and detects the next movement.

  FIG. 10 is a flowchart for explaining the operation of the relay device 2 in response to the attribution request and the attribution cancellation request from the mobile terminal 1.

  This flow is started after activation such as power-on of the relay device 2.

  First, the authentication unit 204 waits for an attribution request (S500) or an attribution cancellation request (S511) from the mobile terminal 1. When the authentication unit 204 receives the attribution request from the mobile terminal 1 (YES in S500), the authentication unit 204 performs authentication by collating the ID and password of the mobile terminal 1 included in the attribution request with a pre-registered ID and password (S501). ). In the case of authentication NG (NO in S502), the authentication unit 204 transmits an attribution response (non-permission) to the mobile terminal 1 (S504), returns to S500, and waits for the next request.

  Receiving the instruction, the relay unit 203 starts relaying (S510). Then, the authentication unit 204 returns to S500 and waits for the next request from the portable terminal 1.

  On the other hand, when the authentication unit 204 receives an attribution cancellation request from the portable terminal 1 (YES in S511), the authentication unit 204 performs an attribution cancellation process and transmits an attribution cancellation response to the portable terminal 1 (S512). Then, the authentication unit 204 instructs the relay unit 203 to stop relay processing for the mobile terminal 1. Receiving this, the relay unit 203 stops the relay. Then, the authentication unit 204 returns to S500 and waits for a request from the next portable terminal 1.

  The embodiment of the present invention has been described above.

  In the present embodiment, the mobile terminal 1 monitors the usage record of application programs stored in the mobile terminal 1 and deletes application programs that have not been used for a predetermined period of time.

  Further, the mobile terminal 1 classifies the usage record by monitoring the usage record of the application program according to whether it belongs to the relay device 2 (online) or not (offline). . Then, the mobile terminal 1 deletes the application program of the class that is used only online when the relay device 2 moves from the service area 5 to the outside of the service area 5.

  In addition, when the mobile terminal 1 moves from outside the service area 5 to the service area 5 of the relay device 2, the mobile terminal 1 receives a list of application programs from the relay device 2 and does not download an application program that has been deleted as unused in the past. In addition, only the application program used online and the new application program are downloaded and stored. Further, the portable terminal 1 automatically executes an application program of a class used online when online.

  Thus, although the portable terminal 1 downloads and uses an application program from the relay apparatus 2, it can automatically delete an unused application program. Further, the mobile terminal 1 can delete an application program used only online when offline. Furthermore, the portable terminal 1 can automatically execute an application program used online. Therefore, the mobile terminal 1 can use a wide variety of applications with the minimum necessary resources.

  In addition, this invention is not limited to said embodiment, Many deformation | transformation are possible within the range of the summary.

  For example, in the above embodiment, the mobile terminal 1 and the relay device 2 are connected by short-range wireless communication, but may be connected by general wireless communication such as a wireless LAN.

  In the above-described embodiment, the relay device 2 connected to the mobile terminal 1 by wireless communication and relaying between the mobile terminal 1 and the network 3 has a function of transmitting an application program. However, the present invention is not limited to this. For example, a dedicated server device connected to the network 3 may be used.

  In the above embodiment, once deleted, the application program cannot be automatically downloaded thereafter. When the mobile terminal 1 receives the application program list belonging to the repeater 2 so that the deleted application program can be downloaded again, the list is displayed on the display unit of the mobile terminal 2 and the user manually It may be possible to select and download.

  In the above embodiment, the functional configurations of the mobile terminal 1 shown in FIG. 2 and the relay device 2 shown in FIG. 5 are integrated logic such as ASIC (Application Specific Integrated Circuit) and FPGA (Field Programmable Gate Array). It may be realized in hardware by an IC, or may be realized in software by a computer such as a DSP (Digital Signal Processor).
