DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection service for a telecommunications network, and more particularly to a communication system for providing a connection service when a called subscriber is in a call stop state.

[0002]

2. Description of the Related Art In a conventional telecommunications network connection service, when a called subscriber is suspended from calling due to tax payment delinquency, a notice to that effect is sent to a person to be notified. During the period in which the taxpayer does not follow the notice and continues to pay tax delinquencies, only the voice guidance is given to the calling subscriber, and the call cannot be connected until the call suspension of the called subscriber is released. .

SUMMARY OF THE INVENTION A communication system according to the present invention is a connection of a telecommunications network comprising an originating subscriber terminal, a telephone exchange network comprising an originating exchange and a destination exchange, and a destination subscriber terminal. In a call connection from a calling subscriber to a called subscriber in a service, if the called subscriber is suspended due to delinquency of a fee to be paid by the called subscriber to use the connection service, the incoming call is terminated. A call connection operation to a caller is put on hold, and a connection instruction execution unit having a function of notifying the originating exchange of a call suspension signal is provided in the terminating exchange, and the call origination exchange receives the call suspension signal. A voice guidance processing unit for notifying a subscriber of a call stop state, and a call holding state in a call stop state in response to a connection request by a terminal operation of the calling subscriber in response to the call stop state notification A connection instruction transmitting unit for notifying a call exchange instruction to a terminating exchange to a terminating exchange is provided in the originating exchange, and the connection instruction execution unit transmits the call connection instruction to the suspended subscriber. It has a function of resuming a call connection with a subscriber.

[0006] In the above-mentioned communication system, it is characterized in that the calling subscriber can make a call by paying a fee different from the fee.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described in detail with reference to FIGS. A calling signal 10 is sent from the calling subscriber 1, and the calling exchange 2 returns a dial tone 11 when the calling is permitted. When the originating subscriber 1 inputs the number of the terminating subscriber 4 by push button, a PB signal 12 is sent to the originating exchange 2 and routing 13 to the terminating exchange 3 is performed according to the number. In the receiving side exchange 3, when the receiving subscriber 4 is the target of the call stop, the stop side notification 14 is sent to the calling side exchange 2. In the voice guidance processing unit 20 of the originating exchange 2, the voice communication 15 to the calling subscriber 1 is not possible because the receiving party has stopped the voice communication by voice guidance 15, but the call (connection) cannot be made. Connection is possible. In response to the voice guidance, the originating subscriber 1 inputs a push button indicating that he / she wants to connect,
The connection request 16 is transmitted, and the connection request transmitting unit 30 that has received the connection request 16 transmits a connection instruction 17 to the receiving side exchange 3. The connection instruction execution unit 40 of the receiving side exchange 3 transmits the incoming call signal 18 and receives the response signal 19 from the receiving subscriber 4, completes the connection, and makes the telephone call ready.

[0008]

According to the present invention, a call can be made even if the called subscriber is in a call stop state and the calling subscriber needs an emergency call.
