Abstract

PURPOSE:To obtain the system able to receive a subscriber identification number being a unique number given to each service subscriber without addition/revision of a program of an existing exchange. CONSTITUTION:This system is provided with a subscriber identification number receiver 20 whose input side connects to a subscriber circuit 16 of an exchange and whose output side connects to an interface circuit 14 of the exchange. A telephone number of a service subscriber 9 and a subscriber identification number are registered in advance to the receiver with cross reference. A DTMF reception circuit 4 receives a subscriber telephone number and a subscriber identification number of the service subscriber 9 sent from the caller subscriber 18. A central controller 6 collates the received number with a number registered in advance and an MF transmission circuit 5 sends the received subscriber telephone number to an MF reception circuit 15 via interface circuits 13,14 when they are coincident. The exchange interrupts the subscriber circuit 10 via an interrupt circuit 12 and an interrupt connection network 11 based on the received subscriber telephone number to allow the circuit 10 to make dialing.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is unique to service contract subscribers and is necessary when applying services provided by telephone exchanges without limiting to outgoing calls from telephone terminal devices of service contract subscribers. The present invention relates to a subscriber identification number receiving method for receiving the identification number of the subscriber.

[0002]

2. Description of the Related Art As a method of receiving this kind of subscriber identification number, a subscriber identification corresponding to the telephone number of each subscriber terminal accommodated in the telephone exchange and provided with a service in a storage device in the telephone exchange. A number lookup table is provided, and when a call arrives at a subscriber terminal, the subscriber identification number sent from the calling side is received, and after checking this table, the telephone exchange program is added or changed to execute various services. Then the corresponding method is taken.

[0003]

In the above-mentioned conventional method, since the program of the exchange is added or changed, it is required to re-verify all the functions of the exchange in consideration of the adverse effect on the existing function due to the bug. Further, in a network in which a plurality of different types of telephone exchanges are in operation, there is a drawback that different changes are required for each type and it is not possible to respond quickly.

An object of the present invention is to provide a subscriber identification number receiving system capable of receiving a subscriber identification number without adding or changing a program of an existing exchange.

[0005]

According to the subscriber identification number receiving system of the present invention, an input side is connected to a subscriber circuit of an exchange and an output side is connected to a trunk circuit of the exchange, and a unique number is given to each service subscriber. A means for receiving and identifying a subscriber identification number, which is a number, is provided, and in this means, the subscriber telephone number of the terminal accommodated in the exchange and provided with the service is registered in advance in association with the subscriber identification number. When the exchange receives a predetermined special number, the exchange activates the means through the subscriber circuit, and the means transmits the subscriber telephone number of the service subscriber transmitted from the calling side and the subscriber telephone number. When the subscriber identification numbers are received, the received subscriber telephone numbers and the corresponding subscriber identification numbers are compared with each other, and when they match, the received subscriber telephone numbers are transferred to the trunk circuit. Through sent to the exchange, the exchange is an interrupt to the subscriber circuit of the relevant based on the subscriber telephone number received is a configuration in which the calling.

[0006]

The present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing the configuration of an exchange system for explaining an embodiment of the present invention. In FIG. 1, a subscriber identification number receiving apparatus 20 that receives and identifies a subscriber identification number, which is a unique number assigned to each service subscriber 9, receives an input side from a call path switching network 8 of an existing exchange. The subscriber circuit 16 is connected via the detection circuit 2 and the output side is connected by the interface circuit 14 via the interface circuit 3. Subscriber identification number receiver 20
In addition to these interface circuits, the call path switching network 1, the DTMF receiving circuit 4 for receiving the DTMF signal from the calling subscriber 18, and the MF for the existing exchange.
An MF transmission circuit 5 for transmitting a signal, a central controller 6,
A maintenance operation console 7 is provided.

The existing exchange comprises a subscriber circuit 10 connected to a service subscriber 9 and an interrupt connection network 11.
An interrupt circuit 12, a DTMF receiving circuit 13, an interface circuit 14, an MF receiving circuit 15, a subscriber circuit 16 connected to the subscriber identification number receiving device 20, and an incoming trunk circuit 19.

Next, the operation of the service application example according to the present invention will be described with reference to FIG. The telephone of the service subscriber is the service subscriber 9 in FIG. 1, but the operation when accessing the contract service using the telephone at the destination is shown. First, a calling subscriber 18 who is out of the office dials a telephone number of a subscriber code 16 for receiving a station number and a predetermined identification number. The existing exchange receives this via the telephone network 17 and the incoming trunk 19, whereby one of the subscriber circuits 16 is selected, and the identification number receiving device 20 detects that there is an incoming call by the incoming call detecting circuit 2. Then, the call is connected to the DTMF receiving circuit 4 via the communication path switching network 1 according to an instruction from the central control device 6.

Next, by sending a dial tone from the DTMF receiving circuit 4, the calling subscriber 18 dials the telephone number of the home, in this case, the service subscriber 9 + the subscriber identification number. When the central control unit 6 determines that the dialed number and the home telephone number and subscriber identification number stored in the storage device (not shown) of the central control unit 6 in advance match, the central control unit 6 stores The telephone number is sent from the MF transmission circuit 5 to the existing exchange side via the interface circuit 3.

In the existing exchange, the MF signal is received by the MF receiving circuit 15, and the interrupt circuit 12 and the interrupt connection network 11 are provided to the subscriber circuit 10 of the service subscriber 9.
And the call is connected through the call switching network 8.

As described above, the service subscriber can make a call from the home telephone by using the telephone at the destination, and can use various services contracted to the home telephone. As examples of services, it is possible to change the transfer destination from outside the home or to make an international immediate call.

[0013]

As described above, according to the present invention, by adding means for receiving the subscriber identification number to the exchange,
This has the effect that this service can be applied to a service contract subscriber using a terminal on the go without changing the existing exchange.
