  Next, the operation | movement which concerns on this invention among the operation | movement of the communication system 1 mentioned above is demonstrated, referring FIG.3 and FIG.4. FIG. 3 is a sequence diagram showing the operation of the communication system 1. FIG. 4 is an explanatory diagram conceptually showing the flow of information in the communication system 1.

  First, when the receiving user UB operates the receiving communication terminal 12, the receiving communication terminal 12 transmits user information to the PR server 22 (step S11 in FIG. 3, arrow (A) in FIGS. 3 and 4). ).

  Now, the description will be continued assuming that the user information includes presence information indicating “on the train”. Further, in the transmission media format table stored in the storage device of the APL server 24, “inside the train” as presence information and “text format” as the media format are stored in association with each other. Suppose.

  As a result, the PR server 22 receives user information from the receiving communication terminal 12, and stores the received user information and terminal identification information for identifying the receiving communication terminal 12 in association with each other (user information). Part of the reception process).

  Thereafter, when the transmitting user UA operates the transmitting communication terminal 11, the transmitting communication terminal 11 transmits a call request including receiving terminal identification information for identifying the receiving communication terminal 12 to the CC server 21 ( Step S12 in FIG. 3, arrow (1) in FIGS. 3 and 4).

  Next, when receiving a call request from the transmission side communication terminal 11, the CC server 21 includes reception side terminal identification information included in the call request and transmission side terminal identification information for identifying the transmission side communication terminal 11. A call notification is transmitted to the APL server 24 (step S13 in FIG. 3, arrow (2) in FIGS. 3 and 4).

  When the APL server 24 receives the call notification from the CC server 21, the APL server 24 transmits a user information request including the terminal identification information included in the received call notification as the terminal identification information to the PR server 22 (FIG. 3). Step S14, arrow (3) in FIG. 3 and FIG.

  Next, when the PR server 22 receives the user information request from the APL server 24, the PR server 22 displays the user information stored in association with the terminal identification information included in the user information request in accordance with the received user information request. 24 (step S15 in FIG. 3, arrow (4) in FIGS. 3 and 4 and part of the user information receiving step).

  When the APL server 24 receives user information from the PR server 22, the APL server 24 selects the second media format based on the received user information and the stored transmission media format table. According to the above assumption, the APL server 24 selects the text format as the second media format. Then, the APL server 24 transmits the transmission media information representing the selected second media format (here, the text format) to the MR server 23 (step S16 in FIG. 3, arrow (5) in FIGS. 3 and 4). , Part of the conversion process).

  Next, the APL server 24 transmits an instruction for establishing a session between the transmitting communication terminal 11 and the MR server 23 to the CC server 21. Furthermore, the APL server 24 transmits an instruction for establishing a session between the receiving communication terminal 12 and the MR server 23 to the CC server 21 (step S17 in FIG. 3, arrow 6 in FIG. 3 and FIG. 4). )).

  Then, the CC server 21 transmits a message for establishing a session between the transmitting communication terminal 11 and the MR server 23 to the transmitting communication terminal 11 and the MR server 23 (steps S18, FIG. 3 and FIG. 3). Arrow (7) in FIG. As a result, a session is established between the transmitting communication terminal 11 and the MR server 23 (controlled (set) so that the transmitting communication terminal 11 and the MR server 23 can communicate with each other).

  Next, the CC server 21 transmits a message for establishing a session between the receiving communication terminal 12 and the MR server 23 to the receiving communication terminal 12 and the MR server 23 (step S19 in FIG. 3, FIG. 3 and FIG. 3). Arrow (7) in FIG. As a result, a session is established between the receiving communication terminal 12 and the MR server 23.

  Then, the transmitting user UA inputs the content information to the transmitting communication terminal 11 in a voice format (first media format) by speaking. Thereby, the transmission side communication terminal 11 transmits the content information input by the transmission user UA to the MR server 23 (step S20 in FIG. 3, arrow (8) in FIG. 3 and FIG. 4).

  Next, the MR server 23 receives content information from the transmission side communication terminal 11 (content information receiving step). The MR server 23 converts the received content information from a voice format to a text format (second media format) (step S21 in FIG. 3, part of the conversion process).

  Then, the MR server 23 transmits the converted content information to the receiving communication terminal 12 (step S22 in FIG. 3, arrow (9) in FIGS. 3 and 4, content information transmission step). Thereby, the receiving communication terminal 12 receives the content information in the text format. As a result, the receiving user UB can receive the content information in the text format.

  Next, a case where user information including presence information indicating “outside the train” is transmitted from the receiving communication terminal 12 to the PR server 22 will be described. Further, in the transmission media format table stored in the storage device of the APL server 24, “outside of train” as presence information and “voice format” as media format are stored in association with each other. Suppose.

  In this case, the APL server 24 selects the audio format as the second media format. Therefore, when the MR server 23 receives the content information in the audio format from the transmission side communication terminal 11, the MR server 23 transmits the received content information to the reception side communication terminal 12 without conversion. Thereby, the receiving-side communication terminal 12 receives the content information in a voice format. As a result, the receiving user UB can receive the content information in a voice format (that is, listen to the voice uttered by the transmitting user UA).

  Further, the communication system 1 operates in the same manner as described above even when the transmission user UA inputs content information in the text format (first media format) by operating the transmission side communication terminal 11.

  Specifically, the APL server 24 selects the second media format based on the user information input by the receiving user UB. When the audio format is selected as the second media format (that is, the first media format is different from the second media format), the MR server 23 accepts it from the transmission side communication terminal 11. The content information is converted from the first media format (text format) to the second media format (voice format), and the converted content information is transmitted to the receiving communication terminal 12.
