Instant presence system for a guaranteed call connection
First Claim
1. A subscriber location determination system operable in a communications network for extending an incoming call to a determined present communication location of a subscriber, who is the called party comprising:
- means, located in said communication network, for storing subscriber location data that identifies a present communication location in said communications network for a subscriber, who is the called party;
means, responsive to receipt of an incoming call from a calling party and directed to a listed directory number of said subscriber, for retrieving said stored subscriber location data from said means for storing;
means for extending said incoming call to a communication location in said communications network identified by said retrieved subscriber location data when said present communication location in said communications network for said subscriber differs from said listed directory number of said subscriber,means for determining an identity of said calling party;
means for comparing said determined identity of said calling party with call filter data stored in said means for storing subscriber location data; and

Abstract
The instant presence system authoritatively determines the present communication location of a subscriber, who may be at any of a number of possible locations. When the subscriber changes their location, they can use a subscriber communication device that is operational at their new location to update their point of presence on the telephone communication network. The instant presence system enables the communication network to complete a communication connection from a calling party to the called party with certainty. The calling party therefore can reach the called party with certainty by simply dialing a single listed directory number associated with the called party, relying on the instant presence system to complete the call connection to the called party, regardless of the present location of the called party.

6. A method of operating a subscriber location determination system operable in communications network for extending an incoming call to determined present communication location of subscriber, who is the called party, comprising the steps of;
-
storing in a memory, subscriber location data that identifiers a present communication location in said communications network for subscriber, who is the called party; retrieving, in response to receipt of an incoming call from a calling party and directed to a listed directory number of said subscriber, said stored subscriber location data from said memory; and extending said incoming call to a communication location in said communications network identified by said retrieved subscriber location data when said present communication location in said communications network for said subscriber differs from said listed directory number of said subscriber; determining an identity of said calling party; comparing said determined identity of said calling party with all filter data stored in said means for storing subscriber location data; and activating, in response to said step of comparing authorizing completion of said incoming call, said step of extending. - View Dependent Claims (7, 8, 9, 10)
