[0014]
The connection destination telephone number transmission unit 37 transmits the connection destination telephone number received from the storage control unit 35 to the exchange 32.
[0015]
Next, the operation of the present embodiment will be described in detail with reference to FIG. 4 and FIG.
FIG. 4 is a sequence diagram for explaining the connection destination telephone number storage operation of the embodiment of the recall system according to the present invention, and FIG. 5 shows the repeat call of the embodiment of the recall system according to the present invention. It is a sequence diagram for demonstrating operation | movement.
[0016]
First, the connection destination telephone number storing operation of the present embodiment will be described.
Referring to FIG. 4, when a connection is made from the mobile terminal 10 to the mobile terminal 20, the mobile terminal 10 sends a connection destination telephone number (phone of the mobile terminal 20 as a connection request to the wireless station 31 via the wireless line 2. The wireless station 31 transmits the received connection destination telephone number to the exchange 32 (step A1).
[0017]
The exchange 32 that has received the connection destination telephone number transmits the connection destination telephone number and caller information (phone number of the portable terminal 10) obtained from a known communication procedure to the server 33 (step A2). The connection destination telephone number receiving unit 34 receives the connection destination telephone number and the caller information from the exchange 32, and transmits the received connection destination telephone number and the caller information to the storage control unit 35.
[0018]
Receiving the connection destination telephone number and the caller information, the storage control unit 35 searches the area of the connection destination telephone number storage unit 36 that matches the received caller information, and puts it in the connection destination telephone number column of the corresponding area. The received connection destination telephone number is stored (step A3).
[0019]
Thereafter, the exchange 32 transmits a connection request to the exchange 22 via the PSTN network 4 by a known communication procedure (step A4), and the exchange 22 calls the mobile terminal 20 on the receiving side via the radio station 21 ( Step A5) When the mobile terminal 20 responds to the call, the mobile terminal 10 and the mobile terminal 20 are connected to make a call (Step A6).
[0020]
Next, the re-call operation of the present embodiment when the battery of the mobile terminal 10 occurs during a call will be described.
[0021]
Referring to FIG. 5, when the battery of the mobile terminal 10 is exhausted during a call between the mobile terminal 10 and the mobile terminal 20 based on a call from the mobile terminal 10, the call is terminated (suspended). The owner of 10 inputs the telephone number and password of his / her mobile terminal 10 from the nearest public telephone 11 and makes a connection request to the exchange 12 (step B1). Needless to say, the telephone used by the owner of the mobile terminal 10 does not have to be the public telephone 11 but may be a home telephone, another person's mobile telephone, or the like.
[0022]
The exchange 12 that has received the telephone number and password of the portable terminal 10 from the public telephone 11 as a connection request transmits the received connection request to the exchange 32 via the PSTN network 4 (step B2).
[0023]
The exchange 32 that has received the connection request, that is, the telephone number of the mobile terminal 10 and the password, determines that it is a re-call request without a connection destination telephone number by receiving the password together with the telephone number of the mobile terminal 10 (step B3). The server 33 transmits the telephone number of the portable terminal 10 for which the connection request has been made to the server 33 as caller information, and inquires about the connection destination telephone number (step B4).
[0024]
The connection destination telephone number receiving unit 34 of the server 33 receives the caller information (phone number of the portable terminal 10) and the password from the exchange 32, and stores the received telephone number and password of the portable terminal 10 in the storage control unit 35. Send. The storage control unit 35 receives the password together with the caller information (phone number of the mobile terminal 10) and determines that it is an inquiry of the connection destination telephone number, and the received caller information (phone number of the mobile terminal 10) and The area of the caller information that matches is retrieved, the password of the corresponding area is read out, compared with the password received from the exchange 32, and if the two match, the connection destination telephone number (of the portable terminal 20) Phone number) is read (step B5), and the telephone number of the portable terminal 20 is transmitted to the connection destination telephone number transmission unit 37. The connection destination telephone number transmission unit 37 sends the telephone number of the portable terminal 20 to the exchange 32 and the connection destination telephone. It transmits as a number (step B6).
[0025]
The exchange 32 transmits a connection request to the exchange 22 via the PSTN network 4 based on the telephone number of the portable terminal 20 received from the server 33 (step B7). The exchange 22 receives the reception side via the radio station 21. The portable terminal 20 is called (step B8), and the portable terminal 20 responds to the call, so that the portable terminal 10 and the portable terminal 20 are connected to enable a call again (step B9). It should be noted that when the connection request from the exchange 32 to the exchange 22 is made, the telephone number of the portable terminal 10 can be transmitted as the caller information. In this case, the call is sent from the public telephone 11. Instead, the mobile terminal 20 can recognize that the call originates from the owner of the mobile terminal 10.
[0026]
In the present embodiment, the telephone number to be transmitted for the re-calling is the own telephone number (the telephone number of the mobile terminal 10), but the telephone number to be transmitted for the re-calling is a predetermined telephone number. In this case, the telephone number (phone number of the mobile terminal 10) and the password are input after transmitting a predetermined telephone number for a re-call.
[0027]
As described above, according to the present embodiment, when the call ends due to the battery of the mobile terminal being exhausted during a call, the connection stored in the server 33 is stored even if the destination telephone number is not stored. By using the destination telephone number, it is possible to establish a re-call with the other party using a telephone such as a public telephone, and there is an effect that it is not necessary to carry a spare battery or a machine equivalent to a charger.
[0028]
Note that the present invention is not limited to the above-described embodiments, and it is obvious that the embodiments can be appropriately changed within the scope of the technical idea of the present invention. In addition, the number, position, shape, and the like of the constituent members are not limited to the above-described embodiment, and can be set to a number, position, shape, and the like that are suitable for implementing the present invention. In each figure, the same numerals are given to the same component.
[0029]
【The invention's effect】
The re-call system and the re-call method of the present invention provides a connection-destination telephone number stored in the server even if the other-party telephone number is not stored when the call ends due to the battery running out of the mobile terminal during the call. By using, it is possible to establish a re-call with the other party using a telephone such as a public telephone, and there is an effect that it is not necessary to carry a spare battery or a machine equivalent to a charger.
