Patent number: 5896441Abstract: A subscriber A accommodated in an SSP is connected to a terminal to which a telephone number is assigned by a number conversion service. The communication state of the converted telephone number becomes in a busy state, and a corresponding SSP number is written in a management table arranged in an SCP. If a fault occurs in the SSP, all of the calls to which a subscriber accommodated in the SSP is connected, are released. Once the SSP is restored from the fault, it notifies the SCP of the SSP number identifying the SSP together with a message notifying that the SSP is restored from the fault. The SCP searches for a management table using the SSP number received from the SSP, and changes all of the communication states of converted telephone numbers corresponding to the corresponding SSP number to an idle state.Type: GrantFiled: December 16, 1996Date of Patent: April 20, 1999Assignee: Fujitsu LimitedInventors: Mitsunori Akazawa, Tetsuya Sakata, Satomi Kawakami
