[Operation]
[First relay function]
FIG. 6 shows a flowchart of the first relay function.

  First, in step S1-1, a call is transmitted from the first mobile terminal device with videophone function 111 to the relay system 113 via the mobile phone network 114 and the general line network 115. The relay system 113 receives a call from the first mobile terminal device with videophone function 111 in step S1-2.

  In step S1-3, the relay device 141 requests the server 142 to refer to the database 143 using the telephone number of the transmission source included in the transmission information as a key. In step S1-4, the server 142 acquires the destination telephone number corresponding to the caller telephone number from the database 143. The server 142 notifies the destination telephone number acquired to the relay device 141 in step S1-5.

  When the relay apparatus 141 acquires the destination telephone number in step S1-6, the relay apparatus 141 makes a call to the destination telephone number notified in step S1-7. When the second mobile phone device 112 with videophone function, which is the destination telephone number, arrives at step S1-8, between the second mobile phone device 112 with videophone function and the relay device 141 at step S1-9. Videophone communication is established. Next, in step S1-10, the relay device 141 establishes videophone communication between the first videophone function-equipped mobile terminal device 111 and the second videophone function-equipped mobile terminal device 112.

  As described above, a videophone call can be performed between the first mobile phone device with videophone function 111 and the second mobile phone device with videophone function 112 paired therewith.

By controlling in this way, it is possible to prevent charging of telephone charges in the standby state.

[Third relay function]
FIG. 8 shows a flowchart of the third relay function.

  First, the server 142 refers to the database 143 in step S3-1, compares the current time with the connection time stored in the database 143, and if there is a connection time corresponding to the current time in step S3-2, In step S3-3, the telephone numbers of the first videophone function-equipped mobile terminal device 111 and the second videophone function-equipped mobile terminal device 112 that are paired are acquired and notified to the relay device 141.

  The relay device 141 makes a call to the telephone number of the first mobile terminal device with videophone function 111 that is paired with the second mobile phone device with videophone function 112 received from the server 142 in step S3-4. In step S3-5, a call is made to the telephone number of the second videophone function-equipped mobile terminal device 112 that is paired with the first videophone function-equipped mobile terminal device 111 received from the server 142.

  When the mobile terminal device 111 with the first videophone function receives a call from the relay device 141 in step S3-6, the first mobile phone device 111 responds to the relay device 141 in step S3-7. When the second mobile phone device 112 with a videophone function receives a call from the relay device 141 in step S3-8, it responds to the relay device 141 in step S3-9.

  When the relay device 141 receives a response from the second mobile terminal device 112 with the videophone function paired with the first mobile terminal device 111 with the videophone function in step S3-10 and videophone communication is established, the relay device 141 is set. In -11, the communication between the first mobile terminal device with videophone function 111 and the second mobile terminal device with videophone function 112 paired therewith is relayed.
