Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a service that requires a change in telephone number in order to receive a new service. The present invention relates to a method of connecting a call using the same number which can be used in the same manner as long as the telephone number has not been changed. 2. Description of the Related Art Conventionally, a telephone number can be used as it is when an area covered by an exchange accommodating a subscriber telephone is moved. However, when a move is made across an accommodation exchange, the telephone number usually changes. Would. There is also a request not to change the telephone number when the telephone number is described in an advertisement, a business card, or the like. In such a case, a service called a branch agency telephone service has been provided. FIG. 7 is a diagram showing the outline of this service. In the case where the receiving subscriber 5 is accommodated in the destination exchange 3 but is accommodated outside the accommodation area of the destination exchange 3 by moving, this service is provided. Is provided. When the calling subscriber 1 calls the called subscriber 5, the telephone number of the called subscriber 5 is 04.
Assuming that the service number is 31-211-7777, the service is based on the premise that the telephone number is not changed.
Dial 1-7777. As a result, the originating exchange 2
Sends a connection request to the destination exchange 3 of the 043-211 station that is the connection destination. Receiving exchange 3 receiving this connection request
Is set to recognize that the receiving subscriber 5 is accommodated outside the accommodation area of its own exchange when receiving the request for the branch substitute telephone service from the receiving subscriber 5. A call is made to the called subscriber 5a which has been relocated to the destination via the relay stations 4a to 4c connected by a dedicated line. Such a function is generally called the same number transfer. [0004] Separately, the ISDN function is not incorporated in the exchange, but the ISDN function is performed without changing the telephone number.
You may want to receive service. In this case, if the ISDN exchange 6 is accommodated in the originating exchange 2 as shown in FIG. 8, the ISDN terminals 7 and 5b can be connected. Such a function is generally called a same-number shift. [0005] However, in the case of the same number transfer, the telephone of the called party becomes a telephone call only for receiving,
Since it is impossible to make a call as it is, when using it for outgoing calls, a new line contract is necessary,
In addition, since a dedicated line is used from the destination exchange to the telephone, it is necessary for the receiving side to bear the dedicated line usage fee. There was a problem that a line contract was required. Also, in the case of the same number transfer, the accommodation exchange
Since it is necessary to accommodate the DN exchange, it is difficult to increase the economic efficiency when the number of users is small, and there is a problem that it is difficult to actually implement the operation. The present invention has been made in view of such circumstances, and is intended to perform the same-number transfer and the same-number transfer with high economic efficiency. SUMMARY OF THE INVENTION In order to solve such a problem, the present invention provides a first subscriber number when a subscriber telephone is accommodated in a first local exchange, The second subscriber number when accommodated in the second local exchange is the first
The first subscriber exchange sends the second subscriber number to the transit exchange when the first subscriber exchange receives a connection request for the first subscriber number. , The transit exchange stops the connection request to the first subscriber number, requests the second subscriber exchange to connect to the second subscriber number, and at least connects the transit exchange and the first subscriber exchange. Signal transmission is performed using a common signal network between the sections. Then, a second subscriber number belonging to the second local exchange and a first subscriber number belonging to the first local exchange are recorded in the subscriber table of the second local exchange. The second local exchange is second
When there is a call request from a subscriber having a first subscriber number , the call request is processed as a call request from a subscriber having a first subscriber number via a common channel signal network. . According to the present invention, when a first local exchange receives a connection request for a first local number, the first local exchange sends a second local number to a transit exchange. Request to connect to the second subscriber number is canceled and a connection request to the second subscriber number is made to the second local exchange. As the second subscriber exchange connects treated as a call request from a subscriber of the its outgoing request when a calling request from a subscriber of the second subscriber number first subscriber number It was done . FIG. 1 is a diagram for explaining the operation when the present invention is applied to the same-number transfer, and the same parts as those in FIG. In this example, the terminating subscriber 5 moves, and from the previous 043-211 station 043-21.
An example at the time of moving to 285 stations will be described. In this case, the destination exchange of the called subscriber 5 becomes the destination exchange 7, and the original destination exchange becomes the source exchange 8. The originating exchange 2 and the transfer source exchange 8 are connected via the originating transit exchange 9 and the destination transit exchange 10, and the transfer destination exchange 7 is also connected to the transit exchange 10. Also, incoming subscriber 5
It is assumed that the original number is 043-217-1777, but has been changed to 043-285-3333. When an incoming call arrives at the incoming subscriber 5, the outgoing subscriber 1
Is not aware of the moving of the incoming subscriber 5
When dialing 7777 (the processing of the number 1 with a circle in FIG. 1), the originating exchange 2 receives 043-21 as the connection destination number.
1-7777 is output and sent to the transfer source exchange 8 via the originating intermediate exchange 9 and the destination intermediate exchange 10 (processing of the numeral 2 with a circle). The transfer source switch 8 determines whether or not the called subscriber has been transferred, based on a subscriber correspondence table provided therein. Further, if it has been relocated, it has subscriber correspondence data indicating whether or not to receive the same number relocation service and the relocation destination telephone number, and the 7777 telephone number is transferred to the subscriber correspondence data. It is assumed that the registration that the relocation destination is 043-285-3333 has been performed. Based on the registration data, the relocation source exchange 8 sends a request for rerouting to the address 7777 with the call destination being 043-285-3333 as the destination.
Notify. It is needless to say that the connection processing is performed by the exchange for the subscriber who has not been relocated. On the basis of this notification, the receiving relay exchange 10 opens the communication path to the transfer source exchange 8 based on the rerouting request, and connects the destination telephone number to the transfer destination exchange 7 (the circled numeral 4). processing). Thereby, the transfer destination exchange 7
Makes a general connection to the transfer destination telephone number 043-285-3333 (the processing of the numeral 5 with a circle). FIG. 2 shows the operation of the transfer source exchange 8
10 is a flowchart showing a process in which a signal which arrives at the destination relay exchange 10 for the subscriber who has been transferred from the destination relay exchange 10 is processed by the transfer source exchange 8 and returned to the destination relay exchange 10 again. As shown in step 100 of FIG. 2, when there is an incoming call from the destination relay exchange 10, the transfer source exchange 8 determines whether or not the transfer indication of the transferred subscriber corresponding data is being transferred as shown in step 101. . When providing services to the relocated subscriber, a table as shown in step 101a is stored in the relocation source exchange 8 in advance. That is, for the subscriber who desires the same number transfer, the transfer indication is registered as "transferring" in this table, and the connection destination telephone number is registered as "transfer destination telephone number". Therefore, when it is determined in step 101 that the transfer indication of the subscriber correspondence data is being transferred, the process of step 102 is performed. That is, the destination telephone number of the disconnection signal (REL) is set to the transfer destination telephone number of the subscriber correspondence data from the transfer source telephone number, the rerouting display is set to "YES", and the destination relay exchange 10 is set. Forward. Step 101
When it is determined that the transfer indication of the subscriber correspondence data is not being transferred, the normal disconnection signal shown in step 103 is transferred to the destination exchange 10. FIG. 3 is a flowchart showing a process in which the receiving-side intermediate exchange 10 receives a signal from the source exchange 8 and connects to the destination exchange 7. As shown in step 110, the destination trunk exchange 10 receives
When the disconnection signal is received, it is determined in step 111 whether or not the rerouting display of the disconnection signal is “YES”. If the rerouting display in the disconnection signal is set to "YES" in step 102 of FIG. 2, the disconnection signal shown in step 111a is supplied, so the process of step 111 is determined to be "YES". For this reason, the destination-side exchange 10 opens the communication path to the transfer source exchange 8 as shown in step 112, and re-translates the called number (telephone number of the transfer-destination telephone) as shown in step 113. As shown in step 114, a connection is made to the transfer destination exchange of the newly translated called number, that is, the transfer destination exchange 7 of 285 stations. If the transfer destination exchange 7 is generally connected to the call received by the rerouting function, the call sent from the destination relay exchange 10 can be sent to the called subscriber 5. If the rerouting display of disconnection is not "YES" in step 111, processing for transferring the disconnection signal to the originating intermediate exchange 9 is performed as shown in step 112a. The above is the terminating subscriber 5 who is the relocated subscriber.
FIG. 4 shows a process of transmitting a call from a relocated subscriber. When there is a call from the transfer destination telephone 5 as shown in step 120, the transfer destination exchange 7 proceeds to step 1
As shown in FIG. 21, it is determined whether or not there is a transfer source ID in the subscriber correspondence data. Step 1 for the new exchange 7
As shown in 21a, the correspondence data of the transfer source ID and the transfer source telephone number is stored as the transfer destination subscriber corresponding data for the transferred subscriber. Therefore, when making a call from the relocated subscriber, step 121 is "YES".
Is determined. Thus, as shown in step 122,
A process for connecting the transfer destination telephone number of the subscriber correspondence data as a caller telephone number (calling ID) is performed. As a result, as shown in step 123, the connection process is performed assuming that the calling ID is the transfer source ID, that is, the connection and the charge calculation are performed assuming that the call originated from the transfer source telephone number. When the transfer destination exchange 7 determines in step 121 that there is no transfer source ID in the subscriber correspondence data, step 1
As shown in FIG. 24, the connection is performed on the assumption that the calling ID is the calling number. FIG. 5 shows an information transfer sequence at the time of an incoming call operation to the called subscriber 5. When the calling subscriber 1 makes a call,
The originating exchange 2 sends a dial tone (D
T) is sent, and the calling subscriber 1 who hears it performs a dial operation and sends a dial signal (0A to J) to the originating exchange 2. Upon receiving this, the originating exchange 2 receives the address signal (IA).
M) is transferred to the originating exchange 9, and the address signal is transferred to the destination exchange 10 and the destination exchange (relocation source), that is, the source exchange 8. As a result, the transfer source exchange 8 transfers the disconnection signal including the transfer destination telephone number and the rerouting request to the destination exchange 10, so that the destination exchange 10 transmits the address signal by the rerouting request to the destination exchange (transfer). Destination), that is, transfer to the transfer destination exchange 7. At this time, the transfer destination exchange 7 transfers the ringing signal (IR) to the called party, that is, the called subscriber 5, and transfers the ringing tone (ring back tone, RBT) to the calling party, that is, the calling subscriber 1. When the called subscriber 5 responds and returns a response signal to the destination exchange 7, the response signal (ANM) is transmitted to the destination exchange 7, the destination relay exchange 10, the originating relay exchange 9, and the originating exchange 2. , The calling subscriber 1 and the receiving subscriber 5
A call is made with. Although the above description is for the same-number transfer, the same-number transfer can be processed with the same configuration. FIG. 6 is a diagram showing an example when performing the process of shifting to the same number, and is a diagram for explaining when the calling subscriber 1 connects to the called subscriber 5.
The receiving subscriber 5 originally had the analog terminal 5 connected to the source exchange 5, but the source exchange 8
Since no exchange is accommodated, it is assumed that the transition has been made to use the ISDN terminal 5a connected to the ISDN exchange 7a accommodated in the destination exchange 7 having the function. In this case, the calling subscriber 1 dials the telephone number of the original called subscriber 043-211-5555 without being aware of the transfer of the called subscriber 5 (processing of the number 1 with a circle). The originating exchange 2 has its connection destination number 04
31-211-5555 is connected to the transfer source exchange 8 via the originating intermediate exchange 9 and the destination intermediate exchange 10 (processing of numeral 2 with a circle). The transfer source exchange 8 performs step 1 in FIG.
01a has the same data as that of the transfer source subscriber,
The destination telephone number is stored in the subscriber correspondence data as the connection destination telephone number. Therefore, the source exchange 8
Determines that 043-211-2555 has been transferred, and transfers the transferred number to the transfer-destination number 043-285-66.
66, add a rerouting request, and transfer it to the destination exchange 10. On the basis of the rerouting request, the receiving-side intermediate exchange 10 releases the communication path to the source exchange 8, and then connects the destination telephone to the destination exchange 7 (the process of numeral 4 with a circle). . As a result, the transfer destination exchange 7 connects to the ISDN terminal 5a via the ISDN exchange 7a (processing of the numeral 5 with a circle). When a call is transmitted from the ISDN terminal, the transfer source ID is registered in advance in the corresponding data of the transfer destination switching station 7,
The caller ID registered at the time of calling is transmitted, and connection and charge processing are performed using the transfer source telephone number. Since signals other than voice signals are exchanged between the exchanges via a common signal line network, various controls can be performed more easily than when a control signal is transmitted using a communication line. As described above, according to the present invention , the first subscriber number when accommodated in the first subscriber exchange in the subscriber table and the second subscriber exchange accommodated in the second subscriber exchange. Is stored in association with the second subscriber number when the
Together when connected to the second subscriber number with reference to the subscriber table when receiving a connection request to the subscriber number
Is the second local exchange a subscriber of the second subscriber number?
From the first subscriber number,
The connection processing is performed as a call request from the subscriber of the number, so the outgoing subscriber can dial the old number even if the number of the receiving subscriber changes, so that the calling subscriber knows the change of the number of the receiving subscriber Since there is no need, the same operation as before can be performed , and the telephone number and charge management can be performed as before without any change .
