When the media GW server 12 receives a special number set in advance from the public telephone 11, the media GW server 12 recognizes that the call is made by the special number, obtains dedicated guidance information from the media server 15 via the circuit switch 13, and obtains this information. In addition to being transmitted to the telephone set 11, the caller's subscriber number and NW (network) code number entered by the caller at the public telephone set 11 are acquired in accordance with the dedicated guidance, and this is notified to the circuit switch 13 for voice call connection processing. Make a request.

As shown in FIG. 2A, the circuit switch 13 has the same functional configuration as the circuit switch 17 (FIG. 2B). The circuit switch 13 operates as a circuit switch on the transmission side, and the circuit switch 17 Operates as a circuit switch on the receiving side.
As shown in the functional configuration diagram of FIG. 2A, the circuit switch 13 includes a receiving unit 13a, a notification unit 13b, a circuit switching unit 13c, and a call control non-establishment detecting unit 13d. The function is realized by an arithmetic processing unit (CPU) (not shown) executing a program.

In the circuit switch 13 that operates as a circuit switch on the transmission side, the receiving unit 13a exchanges data with the media GW server 12, and when the guidance connection request is received from the media GW server 12, the dedicated guidance is received from the media server 15. Get information.
When receiving the voice call connection processing request from the media GW server 12 via the receiving unit 12a, the notification unit 13b notifies the user information management database device 16 of caller information described later together with the voice call connection processing request. Then, inquiries about the incoming side area information are made, and the destination information is acquired from the user information management database device 16 as a response.

The circuit switching unit 13c transmits a voice call connection processing request addressed to the telephone number specified from the destination information to the circuit switch 17, and the telephone number of the connection destination specified by the user information management database device 16 and the public telephone 11 is established for call connection.
Further, when a “voice call connection processing response (timeout)” for notifying a session timeout is notified as a response to the voice call connection processing request from the circuit switch 17 on the receiving side, the line switching unit 17 does not accept a call such as a session timeout. The user information management database device 16 is notified that the establishment has been detected.

The call control non-establishment detection unit 13d performs the same processing as the call control non-establishment detection unit 17d described later when operating as a circuit switch on the receiving side.
On the other hand, as shown in the functional configuration diagram of FIG. 2B, the circuit switch 17 includes a receiving unit 17a, a notification unit 17b, a circuit switching unit 17c, and a call control non-establishment detecting unit 17d. These functions are realized by an unillustrated arithmetic processing unit (CPU) executing a program.

The receiving unit 17a and the notification unit 17b perform the same processing as the above-described receiving unit 13a and the notification unit 13b when operating as a circuit switch on the transmission side.
When the circuit switching unit 17c receives a voice call connection processing request from the circuit switch 13 on the calling side, the circuit switching unit 17c performs a paging process, an authentication / confidential process, etc. for the designated connection destination telephone number, and then issues an incoming call request. Process such as.

If the response to the incoming call request cannot be received within a predetermined time, the call control non-establishment detection unit 17d determines that the call is not established due to a session timeout or the like, and the voice call connection processing response (timeout ) Is transmitted to the circuit switch 13 on the calling side.
The media server 15 transmits guidance information to the circuit switch 13 in response to a request from the circuit switch 13.

As shown in the functional block diagram of FIG. 3, the user information management database device 16 includes a database unit 16a, a group terminal identification information acquisition unit 16b, a terminal information selection unit 16c, an authentication unit 16d, and a call history collection unit 16e. These functions are realized by an arithmetic processing unit (CPU) (not shown) executing a program.
The database unit 16a has a contractor information database. In this contractor information database, the contractor and his family are linked and managed. Further, the NW code number is managed in association with each contractor number which is the telephone number of the mobile phone held by the contractor. Further, the location information of the mobile phone on the receiving side is managed.

The group terminal identification information acquisition unit 16b, when inquired about the incoming side area information from the circuit switch 13, sets the contractor number associated with the same family as the contractor number of the caller notified together with the contract. From the information database.
The terminal information selection unit 16c identifies the contractor number of the connection destination from the contractor numbers associated with the same family as the caller acquired by the group terminal identification information acquisition unit 16b, and receives the specified contractor number. The circuit switch 13 is notified as a side area information inquiry response.

The authenticating unit 16d refers to the contractor information database and authenticates the caller specified by the caller information.
The call history collection unit 16e manages the call history for each contractor number. Specifically, the time zone in which the called party is selected is held when the circuit exchange 13 inquires about the incoming side area information. If the connection is not established on the called side during the inter-group telephone service, the circuit exchange 13 makes another inquiry about the incoming side area information for requesting connection with another family. The call history information may be updated with the inquiry of the incoming side location information as a trigger.
In addition, for each contractor number, the last call history between the telephone having the contractor number and the telephone having the contractor number associated with the same family as the contractor number is collected and stored in the contractor information database. And stored in association with the contractor number.

(Overall operation when calling a special number)
Next, the operation of each unit when a special number is transmitted from the public telephone 11 will be described.
FIG. 4 is a sequence diagram showing the operation of each unit when a special number is transmitted from the public telephone 11.
When the caller inputs a special number for receiving the provision of inter-group telephone service on the public telephone 11, the special number is transmitted from the public telephone 11 (P1), and the media GW server 12 that has received this special number receives the special number. Then, it is determined whether or not the received special number is a number preset as a number for executing the inter-group telephone service (P2). Here, the special number is a preset number and is set to a value that can be easily stored by the user, such as a three-digit number. In FIG. 4, for example, “XXX” is described.

  Then, the media GW server 12 requests the provision of the inter-group telephone service when the number notified from the public telephone 11 matches the special number preset as the number instructing the provision of the inter-group telephone service. The guidance connection request processing for the circuit switch 13 is performed (P3). When the circuit switch 13 is notified of the guidance connection request from the media GW server 12, it transmits it to the media server 15 (P4).

  When notified of the guidance connection request, the media server 15 recognizes that a call is made by a special number from the public telephone 11, and transmits preset dedicated guidance information to the circuit switch 13 (P5). When receiving the dedicated guidance information, the circuit switch 13 performs a guidance connection response process (P6). Specifically, a special number flag is added to the received dedicated guidance information and is transmitted as “special number transmission response + special number flag” to the public telephone 11 via the media GW server 12 (P7).

As a result, a dedicated guidance voice such as “Enter the contractor number. After that, enter the NW personal identification number of that number” is played on the public telephone 11.
The above-mentioned “special number flag” is a flag representing information associated with the implementation of the inter-group telephone service. By notifying the user information management database device 16 of this special number flag, the user information management database device 16 can carry out processing that recognizes this service.

Further, the content of the dedicated guidance described above is not limited to this, and any guidance that instructs the caller to input the contractor number of the caller and the NW code number thereof may be used.
The public telephone 11 is, for example, a push-phone type telephone. When the caller inputs a contractor number and NW PIN in accordance with the dedicated guidance, the call is made of “caller's subscriber number and NW PIN + special number flag”. Person information is transmitted to the media GW server 12 (P11).

Here, the caller's contractor number is the telephone number of the mobile phone held by the caller. The NW personal identification number is a predetermined value set in advance in association with the contractor number, and is set to a value that is easy for the contractor to memorize. In FIG. 4, the contractor number is represented as “0X0-XXXX-XXX1”, and the NW password is represented as “YYYY”.
Upon receiving the caller information, the media GW server 12 transmits a voice call connection processing request together with the caller information to the circuit switch 13 (P12). When the circuit switch 13 receives the voice call connection processing request from the media GW server 12, the circuit switch 13 transmits an “incoming side location information inquiry” for inquiring the incoming side location information to the user information management database device 16. When the circuit switch 13 transmits the incoming side location information inquiry, the circuit exchange 13 also sends the sender information as the receiving terminal identification information together with the incoming side location information inquiry (P13).

  When the user information management database device 16 recognizes that this service request is made by the special number flag when receiving the incoming side area information inquiry from the circuit switch 13, the user information management database device 16 determines the identity of the caller from the contractor number and the NW PIN number. After the confirmation, a connection destination specifying process described later is executed (P14). Then, the telephone number (“0X0-XXXX-XXX2” in FIG. 4) of the connection destination specified by this connection destination specifying process is transmitted to the circuit switch 13 as “incoming side location information inquiry response” (P15).

Further, the user information management database device 16 makes a guidance request to the circuit switch 13 (P16). Specifically, a guidance request for instructing transmission of connection guidance to the public telephone 11 is transmitted to the circuit switch 13.
When the circuit switch 13 receives the guidance request, it makes a transmission request for a preset connection guidance to announce to the media server 15 that it is connected to the other party by voice (P17). Upon receiving the connection guidance transmission request, the media server 15 outputs preset connection guidance information to the circuit switch 13 as a guidance request response (P18).

Further, when receiving the guidance request response, the circuit switch 13 notifies the user information management database device 16 that the guidance request response has been received (P19), and sends the received connection guidance information via the media GW server 12. It transmits to the public telephone 11 (P20, P21).
As a result, an announcement voice such as “confirmed that the contractor is the person himself / herself. Connected to the family.

  In the connection destination specifying process (P14) in the user information management database device 16, if there is no family linked to the contractor number of the caller, the process shifts from P14 to P16 to request connection for error guidance. Is transmitted to the circuit switch 13. As a result, the circuit switch 13 obtains error guidance information indicating that there is no family to be associated from the media server 15 and transmits it to the public telephone 11 via the media GW server 12 (P17 to P21).

As a result, an announcement voice such as “Cannot be connected”, for example, flows as error guidance to the public telephone 11.
Further, the circuit switch 13 sends a processing request for voice call connection between the mobile telephone 20 having the telephone number of the connection destination notified as the incoming side location information inquiry response and the public telephone 11 to the mobile telephone. (P31).

  Upon receiving the voice call connection processing request from the circuit switch 13, the circuit switch 17 performs paging processing, authentication / confidential processing, etc. for the designated telephone number of the connection destination (P32). An incoming call request is sent to the mobile phone 20 to notify the user of the mobile phone 20 that there is a connection request from the public phone 11 to the connected mobile phone 20 (P33). Thereby, for example, the cellular phone 20 that has received the incoming request rings.

  When the user of the cellular phone 20 responds to the ringing of the cellular phone 20, an incoming request response is transmitted from the cellular phone 20 to the circuit switch 17 (P34), and the circuit switch 17 receives the voice call connection processing response. The circuit switch 13 transmits the voice call connection processing response to the public telephone 11 via the media GW server 12 (P36, P37).

  As a result, a series of processing relating to call connection between the public telephone 11 and the mobile telephone 20 having the telephone number designated as the connection destination by the user information management database device 16 is completed. A call connection is established between the telephones and the voice communication is performed in the same procedure as a known process associated with voice communication between telephones. That is, voice communication is performed between the caller using the public telephone 11 and the holder of the mobile phone 20 having the subscriber number associated as the caller's family, that is, the caller's family member. Is called. When the voice communication is established, the family telephone service is also terminated when the voice communication is terminated.

  On the other hand, as shown in FIG. 5, when a voice call connection processing request is made to the connection destination notified by the incoming side in-zone information inquiry response (P15) (P31), If the connection to the mobile phone 20 is not established, the circuit switch 17 does not receive an incoming request response to the incoming request (P33) from the connected mobile phone 20 even after a predetermined time has elapsed. It is determined that there is no response from the telephone set 20, that is, out of service area or power is off, and a voice call connection processing response (timeout) is transmitted to the circuit switch 13 (P40).

When a voice call connection processing response (timeout) is notified from the circuit switch 17, the circuit switch 13 transmits an incoming side area information inquiry to the user information management database device 16 again (P41).
When the user information management database device 16 receives the incoming side in-zone information inquiry from the circuit switch 13 again, the user information management database device 16 recognizes that the connection with the connection destination mobile phone 20 is impossible, and executes the connection destination specifying process to The connection destination is specified (P42), and the incoming call side area information inquiry response is transmitted again to the circuit switch 13 (P43). That is, the voice communication with the holder of the mobile phone 20 having another contractor number associated with the caller's family is attempted.

  The circuit switch 13 makes a voice call connection processing request addressed to the next designated connection destination (P44). The line switch 17 makes an incoming call request (P46) after performing Paging, authentication, concealment, etc. with the specified next-destination mobile phone 20 (P45). When an incoming call request response is received from the designated next-destination mobile phone 20 (P47), a voice call connection processing response is transmitted to the circuit switch 13 (P48). The circuit switch 13 transmits a voice call connection processing response to the public telephone 11 via the media GW server 12 (P49, P50).

  In addition, after the line switch 17 makes an incoming call request to the designated next connection destination mobile phone 20 (P46), if the incoming call request response cannot be received from this connection destination mobile phone 20 again, The circuit switch 17 transmits a voice call connection processing response (timeout) to the circuit switch 13 (P60), and the circuit switch 13 transmits the incoming side area information inquiry to the user information management database device 16 again (P61). Then, the user information management database device 16 is notified via the circuit switch 13 that the incoming request response cannot be received from the connection destination mobile phone 20, and the next connection destination mobile phone 20 is again sent from the user information management database device 16. The telephone number is acquired, and a voice call connection process is performed with the mobile phone 20. This process is repeated.

  Then, when a call destination area information inquiry is made from the circuit switch 13 (P61), in the connection destination specifying process (P62) in the user information management database device 16, the contractor associated with the same family as the caller If there is no other number, the user information management database device 16 transmits a connection request for error guidance to the circuit switch 13 as a response to the circuit-side switch 13 for the inquiry of the incoming side area information (P61) ( P63). As a result, the circuit switch 13 obtains error guidance information indicating that connection with all the family members is impossible from the media server 15, and sends this to the public telephone 11 via the media GW server 12. Transmit (P64 to P67).

  As a result, an announcement voice such as “All family members could not be connected” is played on the public telephone 11 as error guidance. Then, the call connection process is terminated in the same procedure as the known process when the call connection between the telephones cannot be established.

(Processing procedure of connection destination identification process)
Next, the processing procedure of the connection destination specifying process executed by the user information management database device 16 will be described.
FIG. 6 is a flowchart illustrating an example of a processing procedure of the connection destination specifying process.
When the user information management database device 16 receives the incoming side location information inquiry from the circuit switch 13, the user information management database device 16 refers to the sender information notified together with this incoming side location information inquiry, and first, a special number flag is set in the sender information. It is determined whether it has been performed (step S2).
When the special number flag is not set, it is determined as an error. Then, guidance request processing is performed for the circuit switch 13 and error guidance guidance is performed for the public telephone 11 (step S3). Specifically, an error guidance guidance transmission request is made to the circuit switch 13. As a result, the circuit switch 13 sends a request for transmission of error guidance guidance to the media server 15. The media server 15 acquires preset error guidance information and outputs it to the public telephone 11 via the media GW server 12.

As a result, an announcement voice for notifying an error flows to the public telephone 11, and the user recognizes that the numerical value of the special number is incorrect, and receives the inter-group telephone service by taking a response such as calling again. be able to.
On the other hand, if the special number flag is set in step S2, the process proceeds to step S4 to authenticate the caller. Specifically, the caller information is referred to, and it is determined whether the caller's contractor number and NW personal identification number are predetermined values set in advance.

Here, as described above, the user information management database device 16 includes a contractor information database. In this contractor information database, for example, as shown in FIG. doing. Further, although not shown, a preset NW password is managed in association with each telephone number.
In FIG. 7, the contractor numbers “0X0-XXXX-XXX1”, “0X0-XXXX-XXX2”, “0X0-XXXX-XXX3” are managed in association with the family A, and “0Y0-YYYY-YYY1” is managed. Represents that the contractor number is managed in association with the family B.

Then, the user information management database device 16 refers to the contractor information database, acquires the NW code number corresponding to the contractor number of the caller notified as the caller information, and is notified of the acquired NW code number. It is determined whether the NW code number matches.
When these do not match, it is determined as an error. If it is determined that an error has occurred, guidance request processing is performed on the circuit switch 13 and error guidance guidance is provided to the public telephone 11 (step S3). In other words, an error guidance guidance transmission request is sent to the circuit switch 13.

As a result, the circuit switch 13 sends a request for transmission of error guidance guidance to the media server 15. The media server 15 acquires preset error guidance information and outputs it to the public telephone 11 via the media GW server 12.
As a result, an announcement sound for notifying an error flows to the public telephone 11, and the user recognizes that the subscriber number or the NW code number of the caller is incorrect and takes measures such as resetting it. Can receive inter-group telephone service.

On the other hand, when the caller's contractor number and NW PIN number notified as the caller information match the information registered in the contractor information database, the identity of the caller is confirmed and the caller's identity is confirmed. It is determined that the authentication is complete, and the process proceeds to step S6.
In step S6, it is determined whether there is a connection destination candidate. Here, another contractor number linked to the same family as the family linked to the contractor number of the caller notified as the caller information is set as a connection destination candidate.

  In step S6, specifically, the contractor information database is referred to, and the contractor number associated as the same family as the contractor number of the caller is acquired from the contractor number of the caller. That is, when “0X0-XXXX-XXX1” is notified as the caller's contractor number, the caller's contractor number “0X0-XXXX-XXX1” is linked to the family A from the contractor information database of FIG. The family A is associated with the contractor numbers “0X0-XXXX-XXX2” and “0X0-XXXX-XXX3”. That is, it can be seen that the contractor numbers “0X0-XXXX-XXX2” and “0X0-XXXX-XXX3” exist as connection destination candidates.

When “0Y0-YYYY-YYY1” is notified as the contractor number of the caller, the contractor number “0Y0-YYYY-YYY1” of the caller is sent to the family B from the contractor information database of FIG. It can be seen that they are linked, and that there is no other contractor number linked to this family B. That is, it can be seen that there is no connection destination candidate.
If it is determined in step S6 that there is no connection destination candidate, that is, if there is no other contractor number associated with the same family as the contractor number of the caller, an error is determined. . Then, guidance request processing is performed for the circuit switch 13 and error guidance guidance is performed for the public telephone 11 (step S3). In other words, an error guidance transmission request is sent to the circuit switch 13. As a result, the circuit switch 13 sends an error guidance transmission request to the media server 15. The media server 15 acquires preset error guidance information, and outputs the error guidance information to the public telephone 11 via the media GW server 12.

As a result, for example, an error guidance sound for notifying that there is no connection destination candidate is played on the public telephone 11, and the user of the public telephone 11 recognizes that it cannot receive the service provided by the inter-group telephone service. be able to.
On the other hand, if it is determined in step S6 that there is a connection destination candidate, that is, if there is another contractor number linked to the same family as the contractor number of the caller, the process proceeds to step S10. To do. Then, it is determined whether or not there are a plurality of connection destination candidates. When a plurality of connection destination candidates do not exist, that is, when there is only one contractor number associated with the same family as the caller's contractor number, the process proceeds to step S12, and this connection destination candidate is connected to the connection destination candidate. And the incoming side in-zone information inquiry response is transmitted to the circuit switch 13 together with the subscriber number of the connection destination candidate. Also, a connection guidance request is transmitted to the circuit switch 13.

As a result, the circuit switch 13 performs a voice call connection process addressed to the contractor number designated as the connection destination, and sends a transmission request for connection guidance information to the media server 15. The media server 15 outputs the preset connection guidance information to the public telephone 11 via the media GW server 12.
Thereby, the user of the public telephone 11 can recognize that a telephone connection is being made to someone in the family.

  Then, the user information management database device 16 transmits a response to the incoming side in-zone information inquiry from the circuit switch 13 when there is no notification of call non-establishment due to a session timeout or the like from the circuit switch 17 within a predetermined time. If the circuit-side switch 13 does not notify the receiving side location information inquiry again within a predetermined time from the time (step S14), a voice call connection is established between the mobile phone 20 having the designated subscriber number and the public telephone 11. Recognize that it has been established, and terminate the connection destination specifying process. That is, when there is no response from the connection-destination mobile phone 20 to the incoming call request from the circuit switch 17, a voice call connection processing response (timeout) is notified from the circuit switch 17 to the circuit switch 13, and this voice When the call connection processing response (timeout) is notified, the circuit switch 13 transmits the incoming side in-zone information inquiry to the user information management database device 16 again. Conversely, the circuit switch 13 transmits a voice call connection processing response when receiving an incoming request response, which is transmitted when an incoming request response is received from the mobile phone 20 of the connection destination, instead of notifying that the call is not established due to a session timeout or the like. When receiving from the circuit switch 17, no incoming side location information inquiry is transmitted.

  Accordingly, when the user information management database device 16 receives the incoming side location information inquiry from the line switch 13 again within a predetermined time from when the incoming side location information inquiry response is transmitted to the circuit exchange 13, the connection is established. It can be considered that the connection with the previous mobile phone 20 has not been established, and if the receiving side location information inquiry is not received again from the circuit switch 13 within a predetermined time, Can be considered established.

  Accordingly, when a response to the incoming side area information inquiry from the circuit switch 13 is transmitted in the process of step S14, the line side exchange information inquiry is notified from the line exchange 13 within a predetermined time, that is, the circuit switch. If a notification intended to call non-establishment such as a session timeout from 17 is received, it is determined whether there are other connection destination candidates (step S18). Since there are no other connection destination candidates, step S20 is performed. Then, the connection impossible guidance request process is transmitted to the circuit switch 13. Then, the connection destination specifying process ends.

Thereby, the line switch 13 transmits a guidance to the effect that it cannot be connected to the family member to the public telephone 11, and the user can recognize that the connection with any member of the family has failed.
On the other hand, when there are a plurality of connection destination candidates in the process of step S10, a connection destination selection process for selecting a connection destination from the plurality of connection destination candidates is executed (step S22).

Specifically, among the connection destination candidates, the connection destination candidate having the latest call history with the contractor number of the caller is specified as the communication destination.
Here, as described above, the user information management database device 16 manages the call history for each contractor number. For example, as shown in FIG. And the last call history date and time when the call was made with the mobile phone of the contractor number linked as the same family as the contractor number. That is, the last call history date and time with other family members is managed for each family member.

The user information management database device 16 refers to the call history corresponding to the contractor number of the caller, and among the connection destination candidates linked as the same family as the caller contractor number, the contractor number of the caller As a connection destination, the subscriber number of the connection destination candidate with the latest call history date and time is set.
For example, as shown in FIG. 8, a connection destination candidate “0X0-XXXX-XXX2” associated with the call history of the caller's contractor number “0X0-XXXX-XXX1” as the same family as the caller's contractor number. ”And“ 0X0-XXXX-XXX3 ”are set as the other party numbers, the one with the latest call history date and time is selected from these two other party numbers. In the case of FIG. 8, the last call history date and time of the caller's contractor number “0X0-XXXX-XXX1” and the other party number “0X0-XXXX-XXX2” is “2011/08/15 13:15:38”. Yes, the last call history date and time with the other party number “0X0-XXXX-XXX3” is “2011/09/26 21:35:44”. The last call date and time of the caller's contractor number is selected as the connection destination because the other party number “0X0-XXXX-XXX3” is newer.

  When there is a connection destination candidate having a contractor number that is the same as the caller, such as when the caller has a plurality of mobile phones, this connection destination candidate is selected last. In other words, it is considered that the mobile phone 20 whose caller is a contractor is usually possessed by the caller himself. However, if the caller receives this family phone service, it is highly likely that the caller does not have the mobile phone 20 at the present time or is in an unusable state even if he has one. . That is, even if a telephone connection is made to the mobile phone 20 and a call is made, there is a high possibility that no one is on the phone. On the other hand, it is conceivable that the contractor lends the mobile phone 20 to someone in the family. Therefore, the connection destination candidate whose contractor is the same person as the caller is finally selected as the connection destination.

Then, an incoming call side area information inquiry response is transmitted to the circuit switch 13 together with the contractor number selected as the connection destination. Further, a guidance request process is transmitted to the circuit switch 13 (step S24).
As a result, the circuit switch 13 performs a voice call connection process addressed to the contractor number designated as the connection destination and sends a transmission request for connection guidance information to the media server 15. The media server 15 outputs the preset connection guidance information to the public telephone 11 via the media GW server 12.

Thereby, the user of the public telephone 11 can recognize that a telephone connection is being made to someone in the family.
Then, when the user information management database device 16 does not receive an incoming side location information inquiry from the circuit switch 13 within a predetermined time, that is, when there is no notification of call non-establishment due to a session timeout or the like from the circuit switch 17, It is determined that the connection with the mobile phone 20 has been established (step S14), and it is recognized that a voice call connection has been established between the mobile phone 20 having the contractor number designated as the connection destination and the public telephone 11, and the connection destination is specified. The process ends.

  On the other hand, if a call reception area information inquiry is received from the circuit switch 13 again within a predetermined time, that is, if a call non-establishment notification due to a session timeout or the like is received from the circuit switch 17 (step S14), It is determined that the exchange 17 has not been able to connect to the mobile phone 20, and it is determined whether there are other connection destination candidates (step S18). If there are other connection destination candidates, the process proceeds to step S22. Then, the connection destination selection process is performed again. In this case, the connection destination is selected from the connection destination candidates excluding the connection destination candidates previously specified as the connection destination. Then, the process proceeds to step S24, and thereafter, the same process as described above is performed.

If connection is not established even when connection is attempted for all of the plurality of connection destination candidates, and no other connection destination candidates exist, the process proceeds from step S18 to step S20, and the connection impossible guidance request processing is performed. 13 (step S20). Then, the connection destination specifying process ends.
As a result, the line switch 13 transmits a guidance to the effect that it cannot connect to the family members to the public telephone 11 and notifies the user by voice.

That is, as shown in FIG. 8, when the contractor number of the caller is “0X0-XXXX-XXX1”, the last call history with the mobile phone 20 having the partner number “0X0-XXXX-XXX2” Since this is the new destination, the called party number “0X0-XXXX-XXX2” is used as the destination, and a receiving side location information inquiry response is transmitted to the circuit switch 13.
Then, when a receiving side location information inquiry is received again from the circuit switch 13 within a predetermined time, that is, if a notification intended to establish a call such as a session timeout from the circuit switch 17 is received, It is determined that the connection with the mobile phone 20 of the connection destination notified as the service area inquiry response is impossible, and the next connection destination candidate is searched and notified. Then, when there are no other connection destination candidates, a transmission request for rejection guidance is made. Then, the destination selection process is terminated.

(Summary of the first embodiment)
Thus, in the first embodiment, when the caller makes a call to the special number, the contractor number of the caller and the contractor number associated as the same family as the contractor number of the caller A subscriber number with the latest call history is identified, and a telephone connection is made to this subscriber number. That is, a telephone connection is made to the mobile phone number of the family member with the latest call history with the caller.

Therefore, even if the caller does not know the phone number of the family member, such as when the mobile phone is lost, the family is only required to memorize the special number and the phone number and NW PIN number of his / her mobile phone. You can make a phone call to someone.
In addition, when you make a phone connection to someone in your family, if you cannot make a phone connection, such as when the other party is outside the service area, you can switch to someone else in your family and try to make a phone connection. In addition, it is possible to establish telephone connections with family members. Therefore, when you want to tell your family about your safety, such as in a disaster, even if you cannot make a phone call with a family member, you can automatically establish a phone connection with another family member. The caller can make contact with someone in the family who can connect to the phone with a single operation of calling the special number.

  Here, when a telephone call cannot be made because the other party is out of service area, etc., the telephone is called again after a short time. Especially in times of disaster, I want to tell my safety to my family as soon as possible. However, since the number of public telephone users increases, it is necessary to re-order this way in the queue waiting for public telephone use. There is a waste of time, and it is a mental burden in situations where one wants to convey his or her safety as soon as possible.

  As described above, the first embodiment is effective particularly in the event of a disaster because it operates so as to make a telephone contact with someone in the family that can be connected to the telephone. In addition, in this way, since it works to make a phone call with someone in the family who can connect to the phone, even if the caller does not answer the call because the person who made the call is absent, There is no need to redo.

Therefore, it is possible to shorten the time of telephone use per person, and in the situation where there are many public telephone users such as in disasters, more people can use the telephone, that is, telephone contact to family members. Can be done quickly and is effective.
In addition, as a family member who makes a telephone connection first among the family members, the connection to the family member who has the latest call history with the caller is intended. Since we are trying to connect to family members who are most recently connected and expected to have a relatively deep connection, for example, parents who are in constant contact, or phone calls most recently. The first thing you can do is make a phone call to a family member who is most concerned about safety, such as a family member.

Also, for example, there may be changes in the family members who frequently communicate with each other, but since the call with the caller preferentially selects the latest family members, comparisons are made at this time. First, it is possible to contact a family member who is deeply connected, and to make a telephone connection to the family member in an appropriate order according to the situation.
Moreover, after voice communication is established with someone in the family, the interfamily telephone service is terminated when the voice communication is completed. Here, in the event of a disaster, when a contact is made with someone in the family, the family member with the communication communicates the safety of the caller to the other family members. Each family member can recognize the safety of the caller without calling the family member by telephone.

Therefore, when the voice communication with someone of the family member is completed, the family phone service is also terminated, and the caller can be directed to terminate the use of the public telephone.
As a result, especially in situations where there are many public telephone users, such as in the event of a disaster, the use of the public telephone by the caller is terminated when it is finished to inform the safety of the caller to someone in the family for the time being. Can be directed to do. As a result, it is possible to minimize the use of public telephones per person, that is, it is effective because many people can use public telephones more quickly.

(Modification of the first embodiment)
In the first embodiment, the case where connections are made in order from the connection destination candidates with the latest last call history with the caller among the connection destination candidates has been described as the order of telephone connection. It is not a thing. For example, when the call history information is not stored in the contractor information database, such as when the call history information is reset in the user information management database device 16, the call is sent with reference to the communication history information of the sender's mail. The telephone connection may be made in order from the newest family in the time when the mail communication was performed among the family members who performed the mail communication. That is, when a mail server that performs mail transmission / reception processing between the mobile phone 20 and another mobile phone 20 is provided and mail transmission / reception processing is possible, for example, in the user information management database device 16, For each contractor number, a communication history of emails communicated with the mobile phone 20 having another contractor number linked as the same family as the contractor number is collected. Based on this communication history, in the user information management database device 16, for each contractor number, the final mail transmission / reception history with the mobile phone 20 having the contractor number linked as the same family as the contractor number is acquired. Then, this may be stored in association with the contractor number of the mobile phone 20. Moreover, you may set so that a priority order may become high in an order from the newest telephone call date in the last log | history date / time of a telephone call or mail transmission / reception among telephone call history and mail transmission / reception history.

  Further, in the first embodiment, the case where the last call history is connected in order from the newest is described. However, for example, the user gives a priority connection order to the family members in advance by customer control or the like. It is also possible to set it. That is, for example, a configuration in which a priority connection order can be set for a family member, a call history information is held, a communication history information is held, or a priority connection order can be randomly set by a server. For example, at least one of these can be configured. If the priority connection order is set by customer control or the like, this setting is followed. If the priority connection order is not set, the last call history is connected in order from the new family member based on the call history information. When the call history is not held, the last history of mail transmission / reception is connected in order from the new family member based on the mail transmission / reception history information. In addition, when the connection destination cannot be specified based on any of the priority connection order, the call history, and the mail transmission / reception history, the user information management database device 16 is configured to randomly set the priority connection destination. May be.

  In the first embodiment, the case where the family is one group has been described. However, the present invention is not limited to the family, and close friends can be included in the family. It is also possible to set a plurality of groups such as a family group as a group and a friend relationship group, for example. In this case, for example, in the contractor information database, a family group and a friend-related group are individually associated with each contractor's telephone number. And, for example, when entering the contractor number and the NW personal identification number, it is further configured to input group identification information for identifying whether to specify a family group or a friendship group as a group, The user information management database device 16 may be configured to acquire the telephone numbers of the members constituting the group specified by the group identification information.

(Second Embodiment)
Next, a second embodiment of the present invention will be described.
(overall structure)
FIG. 9 is a schematic configuration diagram illustrating an example of the inter-group telephone service providing system 1 according to the second embodiment.
The inter-group telephone service providing system 1 in the second embodiment is further provided with a mail server 18 and a location information management device 25 in the inter-group telephone service providing system 1 in the first embodiment shown in FIG.
The mail server 18 performs mail transmission / reception processing between the mobile phone 20 and another mobile phone 20.

When the special number for requesting provision of the inter-group telephone service is transmitted from the public telephone 11, the location information management apparatus 25 links the existing communication apparatus management server (not shown) as the same family as the contractor number of the caller. Acquires current position information of connection destination candidates to be attached.
The communication device management server is, for example, from a circuit switch that manages the mobile phone 20 according to the location of each mobile phone 20, such as the communication device management server described in Japanese Patent Application Laid-Open No. 2006-345580. The position information of each mobile phone 20 is acquired.

In the user information management database device 16, when there are a plurality of connection destination candidates, the connection destination is determined based on the mobile phone corresponding to the connection destination candidates and the location information of the mobile phone specified by the caller's contractor number. select.
In addition, in the user information management database device 16, when a telephone connection cannot be established with any of the connection destination candidates, the mail server 18 notifies all of the connection destination candidates that a call has been sent from the sender. This notification is performed, for example, by transmitting a message by SMS (short message service).
In addition, the same code | symbol is provided to the same part as the said 1st Embodiment, and the detailed description is abbreviate | omitted.

(Processing procedure of connection destination specifying process in the second embodiment)
Next, the processing procedure of the connection destination specifying process in the second embodiment executed by the user information management database device 16 will be described.
FIG. 10 is a flowchart illustrating an example of a processing procedure of a connection destination specifying process in the second embodiment. In the flowchart illustrating an example of the processing procedure of the connection destination specifying process in the first embodiment in FIG. 6, the process of step S <b> 19 is added. Further, the processing procedure of the connection destination selection process (step S22) is different.
That is, in the connection destination specifying process in the second embodiment, the connection destination selection process in step S22 is performed according to the procedure shown in FIG.

First, in step S32, the location information of the mobile phone corresponding to the caller's contractor number and the connection destination candidate is acquired from the location information management device 25, and the mobile phone corresponding to the caller's contractor number is acquired from the mobile phone. A connection destination candidate located far away is specified (step S34).
Next, the process proceeds to step S36, and when there is only one connection destination candidate present at the farthest distance, the process proceeds to step S38, and this connection destination candidate is determined as the connection destination. On the other hand, if there are a plurality of connection destination candidates present at the farthest, the process proceeds to step S40, and the call history between the plurality of connection destination candidates present at the farthest and the caller's contractor number is referred to. Select the connection destination candidate with the latest call history. Then, the telephone number of the selected connection destination candidate is specified as the connection destination (step S42).

For example, as shown in FIG. 12 (a), there are three members of family A, Mr. A, Mr. A, and Mr. A, and each of Mr. A and Mr. A has two mobile phones. Assume that Mr. A has one mobile phone.
First, the location information of these mobile phones is acquired. Then, the priority is increased from the farthest from the current position of the caller's mobile phone.

  In the case of FIG. 12B, both of Mr. A's two mobile phones are in XX city, and one of Mr. A's wife's two mobile phones is in XX city and the other is in △△ city. One daughter's mobile phone is located in △△ City. If XX city is farther from △ city than XX city where Mr. A's mobile phone is located, first, it is the farthest distance from XX city where caller A's mobile phone is located One mobile phone (0X0-XXXX-XXX3) of Mr. A's wife in the city is set as the first priority for the connection destination.

  Next, since Mr. A's other mobile phone (0X0-XXXX-XXX4) and Mr. A's daughter's mobile phone are both in the city, the caller A's mobile phone (0X0-XXXX-XXX1) Browse call history for. The call history of the caller A's mobile phone (0X0-XXXX-XXX1) and the other mobile phone of Mr. A's wife (0X0-XXXX-XXX4) is 2011/8/15. The last call history date and time between the mobile phone (0X0-XXXX-XXX1) and the daughter A's mobile phone (0X0-XXXX-XXX5) is 2011/9/26. For this reason, the cell phone of Mr. A's daughter (0X0-XXXX-XXX5) whose late call history is later is set as the second priority of the connection destination, and the other cell phone of Mr. A's wife (0X0-XXXX-) XXX4) is set as the third priority. Finally, the priority order of the mobile phone of Mr. A, which is different from the telephone number set as the caller's contractor number in the public telephone 11, is set as the fourth place.

  If the connection destination is specified in this way, the process returns to FIG. 10 and the process proceeds to step S24, and the telephone number of this mobile phone, that is, the contractor number is used as the connection destination in order from the highest priority mobile phone. Send an information query response. If the telephone connection with the specified connection destination cannot be established, the process returns from step S24 to step S14 through step S14 and step S18 as in the first embodiment, and this time the family structure specified above is returned. The connection destination is specified according to the procedure of FIG. 11 from the connection destination candidates excluding the subscriber's mobile phone subscriber number.

If any connection destination candidate, i.e., no family member, can be connected to the telephone, the process proceeds from step S18 to step S19 to perform mail transmission processing, and then proceeds to step S20.
Specifically, in the mail transmission process (step S19), all the connection destination candidates, that is, all family members are notified by mail transmission that the caller has made a call. The mail transmission here may be a message transmission by SMS (short message service) or an electronic mail transmission.

Here, the user information management database device 16 manages, for each contractor number, a contractor number associated with the same contractor number as the same family as the user information management database, as well as a mail address. doing.
Then, the user information management database device 16 obtains e-mail addresses corresponding to all connection destination candidates linked as the same family as the caller's contractor number from the caller's contractor number, and as the same family All the mail addresses associated with the connection destination candidates and the contractor number (telephone number) of the caller are stored in the mail server 18 and a mail transmission instruction is issued.

  In response to this, the mail server 18 has received a call from the "0X0-XXXX-XXX1 (caller's phone number)" to the notified mail address. The message content is set in advance by the user, linked with the contractor number of the caller, and registered in the mail server 18 so that all the members of the caller's family If the telephone connection is not possible, the message content may be acquired from the contractor number of the caller, and an email with the acquired message content may be transmitted to the family members.

As a result, the family member to whom the mail transmission was performed acquires the mail generated by the mail server 18 when the mail member is ready to receive the mail, such as when moving to the area or when the telephone call is terminated. , Can recognize its contents.
In the second embodiment, the location information management device 25 corresponds to the location information collection unit, and the process of step S19 in FIG. 10 corresponds to the mail transmission unit.

(Summary of the second embodiment)
Thus, also in the second embodiment, when the caller makes a call to a special number, the contractor number associated with the caller's contractor number and the same family is selected according to a predetermined priority order. A telephone connection is made. That is, since the telephone connection is made to the telephone number of the caller's family member, the same effect as the first embodiment can be obtained. In the second embodiment, telephone connections are made in order from the mobile phone that is farthest from the mobile phone having the contractor number set by the caller.

  Here, when a disaster occurs, the mobile phone that is located near the caller's mobile phone may be affected by the disaster in the same manner as the caller's mobile phone. Therefore, by establishing telephone connections in order from the mobile phone located farthest from the caller's mobile phone, the telephone connection can be made more efficiently, that is, the telephone connection can be made more quickly.

However, for example, when there is a family service provided on a family basis such as a family discount service, the family It is also possible to link family members by using the family information managed in the service.

That is, in such a family service, since the family members are already linked as the same family, the user can receive the service without performing any registration processing when receiving the interfamily telephone service. it can.
Even if someone in the family changes the phone number of the mobile phone, the family service provider updates the phone number of the mobile phone after the change, so that the corresponding family in the contractor information database The member's phone number will also be changed automatically. Therefore, even if the change of the phone number of the mobile phone is not yet notified to another family member, it is possible to reliably establish a telephone connection to the family member who has changed the phone number.

  Moreover, although each said embodiment demonstrated the case where a telephone connection was made between family members, it is not restricted to this. For example, if there is a specific number service provided for a specific number set by the user, such as a discount service for a call or communication to a specific number set by the user, the communication partner is closely related to the user Can be predicted. For this reason, using the specific number information managed in this specific number service, the above-mentioned priority connection destination information, call history information, communication history information from among the destinations registered in this specific number service The destination may be specified based on a random setting or the like.

For example, when a mobile phone is lent from a company in units of work such as departments, these are generally grouped in units of departments. For this reason, the grouped information may be used to provide a family telephone service between colleagues in the workplace.
In short, if the contractor has already been grouped according to certain conditions, this grouping information can be used to allow the user to perform the grouped contract without any registration processing when receiving the family phone service. Service can be received between the two.
