<SNS specific user registration process>
FIG. 4 shows a sequence of an embodiment of a process for registering an SNS specific user in the SNS specific user table 30a. In the figure, the prefetching unit 25 of the mobile terminal 10 transmits a search request to the SNS server 11 using the nickname (specific user name) of the SNS specific user designated as the user of the device in step S1.

  In step S2, the user ID management unit 43 of the SNS server 11 searches the user ID management table 48a using the nickname of the search request. As shown in FIG. 5, in the user ID management table 48a, user IDs and nicknames are registered for all SNS users. Each time the nickname is changed by the user, the SNS server 11 rewrites the nickname in the user ID management table 48a with the changed nickname.

  In step S3, the user ID management unit 43 of the SNS server 11 returns the user ID corresponding to the nickname of the search request obtained by searching the user ID management table 48a to the mobile terminal 10 as a search response.

  The prefetch unit 25 of the portable terminal 10 confirms with the user whether or not to register the user ID of the search response in step S4. When registering the user ID of the search response, in step S5, as shown in FIG. The user ID of the search response is registered in the SNS specific user table 30a together with the nickname (specific user name) of the search request.

  After registering the user ID in the SNS specific user table 30a in step S5, the prefetch unit 25 confirms with the user whether or not another user ID is to be registered in step S6. If the process proceeds to S1 and registration is not performed, the process ends.

  In addition, in the said embodiment, since the user ID of a specific user is not known with the portable terminal 10, it inquires of the SNS server 11, and the obtained user ID of the specific user is registered into the SNS specific user table 30a. In the system in which the user ID of the specific user is known at 10, it is needless to say that it is not necessary to query the SNS server 11 for the user ID of the specific user.

<Message prefetch processing>
FIG. 7 shows a sequence of an embodiment of a process for prefetching a message and storing it in the message storage unit 30b. In the figure, the prefetching unit 25 of the mobile terminal 10 determines whether or not it is a predetermined cycle of about 1 hour (or several hours), for example, in step S11. If it is a predetermined cycle, it is determined whether or not it is in a standby state in step S12.

  In step S13, the prefetching unit 25 creates message ID prefetch requests including user IDs for all user IDs registered in the SNS specific user table 30a by the number of user IDs registered in the SNS specific user table 30a. To the SNS server 11.

  In step S14, the prefetch handling unit 45 of the SNS server 11 searches the message management table 48b using the transmission source user ID of the message ID prefetch request and the user ID of the SNS specific user, and returns a message ID prefetch response.

  As shown in FIG. 8, the message management table 48b stores the message title and content in association with the sending user ID (user ID of the message creator) and the message ID for each destination user ID. . The message ID is set so that each message can be uniquely identified.

  When searching, an entry in which the transmission source user ID of the message ID prefetch request and the user ID of the SNS specific user match the destination user ID and the transmission user ID in the message management table 48b is searched, and one or a plurality of matching entries are searched. The calling user ID and message ID are obtained for each entry. Then, the transmission user ID and message ID of each of the obtained one or more entries are transmitted to the portable terminal 10 of the requesting user as a message ID prefetching response.

  In step S15, the prefetch unit 25 of the portable terminal 10 compares one or a plurality of message IDs received by the message ID prefetch response with the message IDs stored in the message storage unit 30b. As shown in FIG. 9, the message storage unit 30b stores the message title and content in association with the calling user ID and the message ID.

  When the matching message ID is not stored in the message storage unit 30b, the prefetch unit 25 creates a message D prefetch request including the message ID and transmits it to the SNS server 11 in step S16.

  In step S17, the prefetch handling unit 45 of the SNS server 11 that has received this message D prefetch request reads the message title and content from the message management table 48b using the message ID of the message D prefetch request, and together with the message ID. The message D is transmitted as a prefetch response to the requesting user's mobile terminal 10.

  In step S18, the prefetch unit 25 of the mobile terminal 10 stores the received message prefetch response message ID and message (title and content) in the message storage unit 30b. After this, the process proceeds to step S11.

<Display of SNS page>
FIG. 10 shows an embodiment of a message display screen in which an SNS page is displayed by accessing the SNS server 11 using the browser unit 24 of the mobile terminal 10. On the message display screen, the nickname of the calling user and the title of the message are displayed.

  At this time, the message title is hyperlinked (underlined and colored). The titles T1 and T2 of the messages that have already been read ahead are displayed as hyperlinks in orange, for example, with an underline. When the titles T1 and T2 are selected by clicking, the messages M1 and M2 are read from the message storage unit 30b. Content can be displayed without delay.

  Pre-read messages of a specific user of SNS that a user of a mobile terminal reads every day in a standby state, and display a hyperlink of a pre-read message in a specific color on a message display screen, thereby pre-reading If a certain message is selected, the message can be displayed on the screen instantly without waiting for a response from the network.

  The title T3 of the message that has not been pre-read is displayed as a hyperlink in blue, for example, with an underline. When this title T3 is clicked, the SNS server 11 (for example, http://SNS.jp/view_message) .Pl? Id = 222 & box = inbox), and waits for a response from the SNS server 11 to display the message M3 as a hyperlink.

Moreover, in the said embodiment, it does not specify a nickname (specific user name) from a portable terminal as a key, and searches message ID from the message management table 48b, but converts from a nickname (specific user name) to the user ID of a specific user. Since the message ID is searched from the message management table 48b by specifying this user ID as a key, even if the nickname is frequently changed, the user ID is not changed and every time the nickname is changed. No key change registration is required.
