Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a call connection method based on a connection request from a called party, and in particular, based on a called telephone number corresponding to a calling party, which is stored in advance in a database in the network by the called party, The present invention relates to a call connection method that enables connection to a specific operator with the same reception telephone number.

[0002]

2. Description of the Related Art Conventionally, when an incoming call is received while the called party is busy, the call is stored in the network and when the called party's line becomes free, the calling party and called party are removed from the network. A method of calling and connecting has been proposed. Regarding this, for example, "Akiyama, Mizusawa, Yoshida, Tanaka, Intelligent Work and Network Operation, Corona (1991), page 140", "Noguchi, Suzuki,
Illustrated ISDN-Multipurpose Interface-, Ohmsha (1988), No.
Pp. 143 ". In this method, the connection from the network is based only on the order of acceptance in the network, and no consideration has been given to the connection request on the side of the callee that a caller wants to accept. On the other hand, a call connection method (customized service) based on a limited connection request from the called party has been proposed. Regarding this, for example, "Murase,
Ikejiri, Takei; Service Customization and Customer Control, NTT Technical Journal, Vol.1, No.9, 1989.12 ",
"Uesaka, Amitani; Forerunner of IN Service, Free Dial Service, NTT Technical Journal, Vol.1, No.9, 1989.12". With this method, the connection to the called party is real-time, and when the operator corresponding to the calling party wants to accept the call, each calling party is informed of a different incoming call receiving telephone number or one incoming call telephone. The number had to be accepted, the operator had to put the phone on hold and change to a corresponding operator. Related to this type of method, there are, for example, a CCBS (call back at call end or camp on) service and an advanced toll-free service.

[0003]

In the above-mentioned prior art, no consideration is given to satisfying the connection request from the callee side, and the customized service has a complicated structure and has a problem in operability. An object of the present invention is to store such connection information of the called party including the called telephone number corresponding to the calling party in a database in the network in advance, and to inform the customer of one incoming call telephone number. The point is improved, the call to the called party is once accepted by the network, the busy state of the called party is monitored, the calling party and called party are called from the network when the called party is available, and the called telephone number corresponding to the calling party in the database It is to provide a call connection method that enables connection based on the. Further, it is an object of the present invention to provide a versatile service in which incoming calls are not missed due to storage in the network, and to reduce communication charges and facilitate visits to customers.

[0004]

In order to achieve the above object, a call connection method to a called party according to the present invention is a subscriber accommodation exchange for accommodating a caller having a terminal device and a subscription for accommodating the callee. In a communication network including a private accommodation exchange,
Based on the connection request from the callee, a means (database 3 in FIG. 1) for preliminarily accumulating connection desire information including the called telephone number corresponding to the caller in the network, and controlling the database, and based on the connection desire information. Means for connecting the caller to the callee corresponding to the caller (control station 2), and the caller is informed of one reception telephone number. When an incoming call is detected,
Let the network accept the call once,
The database is searched based on the called telephone number, the called party corresponding to the called party is obtained, and a notification indicating that the called party's vacancy is detected from the subscriber accommodation switch accommodating the called party is given. When received, it instructs the receiving and calling party's accommodation switch to connect the called party and the calling party,
It is characterized in that the called party is connected to the called telephone number that the called party desires to connect.

[0005]

In the present invention, the incoming call to the service provider is discriminated by the network based on the information of the called party corresponding to the calling party stored in the database in advance and the connection is established. This allows
All you need to do is to inform the customer of one reception phone number,
It is possible to specify the called party corresponding to the caller desired by the service provider, provide a versatile service, and never miss an incoming call by storing it in the network. Also,
Since an operator corresponding to the customer can be placed near the customer in a distance, the communication fee can be reduced and the visit to the customer can be facilitated.
