<Embodiment 3>
The third embodiment is a modification of the first and second embodiments described above. In the third embodiment, a case where the management device can distribute the updated version to a plurality of information processing terminals will be described.

FIG. 7 is a block diagram showing the overall configuration of the mobile communication system 1000b according to the third embodiment. The mobile communication system 1000b includes information processing terminals 1a, 1b, ... 1n, and a management device 2b. The information processing terminals 1a, 1b, ... 1n and the management device 2b are connected via the wireless communication network N. The configuration equivalent to that of the first embodiment will be omitted as appropriate in the following description.

The information processing terminal 1a is the same as that of the second embodiment, and the information processing terminals 1b to 1n have the same configuration. However, the version information 112 may be different in each information processing terminal. Further, each information processing terminal may have a different first line status or usage status.

The management device 2b includes a storage unit 21, a transmission unit 22b, a reception unit 23b, and a determination unit 24b. The storage unit 21 stores the priorities 213a, 213b, ... 213n in addition to the updated version 211 and the version information 212. The priorities 213a to 213n are associated with the updated version 211 and the version information 212.

The transmission unit 22b transmits an update notification regarding the update version 211 to each of the plurality of information processing terminals 1a to 1n via the wireless communication network N. The receiving unit 23b receives the difference information from each of the plurality of information processing terminals 1a to 1n. The determination unit 24b determines the priority 213a to 213n of the updated version 211 for each information processing terminal based on the received difference information. The transmission unit 22b of each of the plurality of information processing terminals 1a to 1n is used to determine whether or not to start acquiring the updated version based on the first line status, usage status, and priority in each information processing terminal. The determined priority corresponding to each information processing terminal is transmitted to.

FIG. 8 is a sequence diagram showing a flow of the update control method according to the third embodiment. First, the transmission unit 22b of the management device 2b transmits an update notification to each of the plurality of information processing terminals 1a to 1n via the wireless communication network N (S111a, S111b, ... S111n). At this time, the transmission unit 22b reads the plate information 212 from the storage unit 21, includes the plate information 212 in each update notification, and transmits the plate information 212. Then, the difference information generation unit 14 of the information processing terminal 1a generates difference information indicating the difference between the plate information 212 included in the received update notification and the plate information 112 stored in the storage unit 11 (S112a). After that, the difference information generation unit 14 of the information processing terminal 1a transmits the difference information to the management device 2b (S113a). Similarly, the information processing terminals 1b to 1n generate difference information indicating the difference between the version information 212 included in the update notification and the own version information 112 (S112b to S112n). Then, the information processing terminals 1b to 1n transmit the difference information to the management device 2b (S113b to S113n). Then, the receiving unit 23b of the management device 2b receives a plurality of difference information from each of the information processing terminals 1a to 1n.

The determination unit 24b of the management device 2b determines the priority 213a to 213n of the updated version 211 for each information processing terminal based on the received difference information (S114a). That is, the determination unit 24b determines the priority 213a based on the difference information received from the information processing terminal 1a, determines the priority 213b based on the difference information received from the information processing terminal 1b, and similarly, the information processing terminal 1n. The priority 213n is determined based on the difference information received from.

The determination unit 24b may determine the necessity of updating for each information processing terminal based on the received difference information. For example, when the difference information indicates that there is no difference between the version information 212 of the updated version 211 and the version information 112 of the processing information 111, the determination unit 24b determines that the information processing terminal that has transmitted the difference information does not need to be updated. do. Then, the determination unit 24b determines the priority for the information processing terminal determined to be required to be updated.

Here, the transmission unit 22b transmits the determined priority to the information processing terminal determined to require updating. For example, in FIG. 8, the transmission unit 22b transmits the priority 213a to the information processing terminal 1a and transmits the priority 213b to the information processing terminal 1b (S115a and S115b). On the other hand, the determination unit 24b does not determine the priority 213n for the information processing terminal 1n for which it is determined that the update is unnecessary. Therefore, the transmission unit 22b does not transmit the priority 213n to the information processing terminal 1n. Further, the information processing terminal 1n does not receive the priority 213n. Therefore, the information processing terminal 1n ends the process due to a timeout after a certain period of time or more has elapsed from the transmission of the difference information in step S113n.

Alternatively, the determination unit 24b determines the priority of the information processing terminal determined to require updating to be higher than the priority of the information processing terminal determined to require updating. Then, the transmission unit 22b may transmit the determined priority 213a to 213n corresponding to each information processing terminal to each of all the information processing terminals 1a to 1n.

The information processing terminal 1a receives the priority 213a from the management device 2b. Then, the information processing terminal 1a determines whether or not to start the acquisition of the updated version 211 based on the first line status, the usage status, and the received priority 213a (S102a).
