First Claim
1. A communications terminal apparatus which performs a predetermined communications operation by using a packet transmission network as a communication line and uses services provided by a communications management terminal connected to said packet transmission network, said communications terminal equipment comprising:
- means for communicating predetermined communications management messages with said communications management terminal;
first storing means for storing data of a first information table representing registration information of said apparatus to be registered in said communications management terminal;
second storing means for storing data of a second information table for representing registration information of said apparatus previously registered in said communication management terminal; and
control means for comparing registration information of said first information table with registration information of said second information table, sending a first message to said communications management terminal containing the registration information of said second information table to cause said communications management terminal to delete registration information of said apparatus previously registered in said communications management terminal when the registration information of said first information table differs from the registration of said second information table, sending a second message to said communications management terminal containing the registration information of said first information table to cause said communications management terminal to newly register the registration information of said first information table, and saving the registration information of said first information table into said second information table.

Abstract
Contents of a self-terminal information table are compared with the contents of a registered self-terminal information table at or upon start-up after power-on and if a match is not met therebetween registration is made to the gatekeeper equipment after performing unregister operation thereto, thus ensuring advantageously that the contents of the self-terminal information table used in a self-terminal always match the contents registered in the gatekeeper equipment thereby to enable any associated terminal equipment to use the gatekeeper equipment appropriately.
