Description

  The present invention relates to a mobile phone terminal and a server, and more particularly to a data sharing system and a data sharing method using the mobile phone terminal and the server.

  Conventionally, when data is exchanged between mobile phone terminals, it is performed via another medium (memory card, server computer, e-mail, etc.). In the method of registering data in a server computer and acquiring data from a mobile phone terminal, a huge amount of data is stored in the server. Therefore, the construction and operation of the server becomes a large-scale system. Further, in the conventional method, a procedure for a user who provides data and a mobile phone terminal occurs. As an example of such conventional data sharing, Patent Document 1 describes a method of registering data in a server computer and acquiring data from a mobile phone terminal.

Furthermore, a user management part is good also as a structure which limits the possible range of data sharing for every registered user.

  Next, the operation of the best mode for carrying out the present invention will be described with reference to the drawings. 2 to 4, first, as a precondition, it is assumed that the mobile phone terminal 1 and the mobile phone terminal 2 are registered in the user management unit 331 (FIG. 3) of the relay server 3. That is, the user management 331 can implement a data sharing service between the mobile phone terminal 1 and the mobile phone terminal 2. Also, information (data format) specific to each terminal is held.

  In the following description of the operation, transmission and reception of data and various requests between the mobile phone terminal 1 and the mobile phone terminal 2 and the relay server 3 are performed by the wireless unit 11 in FIG. 2A and the calling side mobile phone in FIG. This is performed between the telephone terminal interface unit 31, the wireless unit 21 in FIG. 2B, and the called mobile phone terminal interface unit 32 in FIG. However, description of the presence of these wireless units and interface units is omitted here.

  First, the shared data request unit 121 (FIG. 2) of the mobile phone terminal 1 uses a mobile application for using the data sharing service. Thereby, the information (telephone number or the like) of the mobile phone terminal 2 holding the data to be shared is designated and a data sharing request is made to the relay server 3 (step S1). The relay server 3 that has received the data sharing request makes an inquiry to the user management unit 331 in its own apparatus. Thereby, it is determined whether the data sharing service can be provided to the mobile phone terminal 1 and the mobile phone terminal 2. It also recognizes terminal-specific information (data format) of each mobile phone terminal (step S2).

  When it is confirmed that the data sharing service can be provided, the shared data disclosure request unit 332 of the relay server 3 makes a disclosure request for sharable data to the mobile phone terminal 2 (step S3). This request is made by means of a short message or the like. When the mobile phone terminal 2 receives a request from the relay server 3, the mobile phone terminal 2 operates a mobile application for using the data sharing service. Further, the user of the mobile phone terminal 2 is not particularly aware of this operation. Upon receiving the shareable data disclosure request, the shared data list creation unit 221 of the mobile phone terminal 2 creates a sharable data list in its own terminal and transmits it to the relay server 3 (step S4). The shared data list reception transfer unit 333 of the relay server 3 receives the sharable data list from the mobile phone terminal 2. Then, as a response to the data sharing request from the mobile phone terminal 1, the sharable data list from the mobile phone terminal 2 is transferred (step S5). The shared data list receiving unit 122 of the mobile phone terminal 1 receives and stores this data.

  With the above operation, the sharable data list of the mobile phone terminal 2 stored in the shared data list receiving unit 122 is displayed on the display unit 15. Next, when data to be shared is selected from the sharable data list by a user operation from the input unit 14 of the mobile phone terminal 1, the shared data list receiving unit 122 requests the selected data to be shared and relays it. A data acquisition request is made to the server 3 (step S6). That is, the shared data list reception transfer unit 333 receives a data acquisition request from the mobile phone terminal 1. After receiving this data acquisition request, the upload request unit 334 of the relay server 3 makes an upload request for the corresponding data to the mobile phone terminal 2 (step S7). When the shared data upload unit 222 of the mobile phone terminal 2 receives this upload request, it uploads the corresponding data to the relay server 3 (step S8). The shared data receiving unit 335 of the relay server 3 receives the uploaded data. The relay server 3 converts the data uploaded from the mobile phone terminal 2 into the data format of the mobile phone terminal 1 using the data conversion unit 336 function if necessary (step S9). The data transfer unit 337 of the relay server 3 transfers the data uploaded from the mobile phone terminal 2 as a response to the data acquisition request from the mobile phone terminal 1 (step S10). When the data transfer is normally performed, the data stored in the shared data receiving unit 335 is deleted.

  When the user of the mobile phone terminal 1 requests other data from the mobile phone terminal 2, step S6 to step S10 are repeated (step S11). Thereby, the user of the mobile phone terminal 1 can use the data of the mobile phone terminal 2 acquired by the above operation (step S12).

  In FIG. 4, when data to be shared between mobile phone terminals is determined in advance, the steps (steps S3 to S6) of transmitting / receiving a sharable data list from the mobile phone terminal 1 to the mobile phone terminal 2 are omitted. May be. This can simplify the procedure.

  In addition, the user management unit 331 of the relay server 3 can be provided with functions such as limiting the direction of data sharing and limiting the range of data sharing for each requested user. As a result, a more detailed data sharing service can be provided, and a privacy information control function can be provided.
