COMMUNICATION REGISTRATION RELEASING METHOD AND COMMUNICATION NETWORK

Japanese Patent JPH06261364

A

PURPOSE: To easily registration-release all registration subscribers at one terminal.

CONSTITUTION: When a subscriber 21 executes a registration operation on a terminal 11, the identifier SID1 and the identifier PID1 of the subscriber 21 are transmitted from the terminal 11 to an exchange 4 as a registration request. The exchange 4 registers SID1 in the area of PID1 in a subscriber data base 3, and registers PID1 in the area of SID1 in a terminal data base 5. When the terminal 11 releases the registration subscriber, the SID1 and release are noticed to the exchange 4. The exchange 4 reads and erases all the subscriber identifiers of the area of SID1 in the terminal data base 5 by SID1, transmits all the subscriber identifiers to the subscriber data base 3 and erases respective SID1 of the area of the subscriber identifiers.
