Abstract

A method and system for providing a dynamic call forwarding service for a subscriber in an IP telephone network is disclosed. When a predetermined telephone number is called from a telephone other than the subscriber'"'"'s home telephone, the subscriber enters a code for location registration. The directory number of the telephone the subscriber is using is determined for location registration. A call for the subscriber'"'"'s home telephone is then routed to the telephone the subscriber used for location registration.

Claims

1. A method for providing a follow-me call forwarding service in an IP telephone network, comprising the steps of:

determining when a subscriber uses an assigned code for data access at a new location which is different from the subscriber'"'"'s directory number;

identifying the directory number of the subscriber'"'"'s new location;

identifying the subscriber from said assigned code;

automatically mapping the directory number of the subscriber'"'"'s new location with a stored directory number, said stored directory number corresponding to the subscriber'"'"'s directory number;

routing a voice call originally for the subscriber at the subscriber'"'"'s directory number to the directory number of the subscriber'"'"'s new location, said routing comprising sending IP data packets to the subscriber'"'"'s new location, the IP data packets being associated with digital samples of said call.

2. The method according to claim 1, wherein the assigned code comprises a login identification code and a password.

5. The method of claim 1 wherein said routing further comprises encapsulating said IP data packets into DOCSIS frames.

3. A system for providing a follow-me call forwarding service in an IP telephone network, comprising:

means for determining when a subscriber uses an assigned code for data access at a new location which is different from the subscriber'"'"'s directory number;

means for identifying the directory number of the subscriber'"'"'s new location;

means for identifying the subscriber from said assigned code;

means for automatically mapping the directory number of the subscriber'"'"'s new location with a stored directory number, said stored directory number corresponding to the subscriber'"'"'s directory number; and

means for routing a voice call originally for the subscriber at the subscriber'"'"'s directory number to the directory number of the subscriber'"'"'s new location, said routing comprising sending IP data packets to the subscriber'"'"'s new location, the IP data packets being associated with digital samples of said call.

4. The system according to claim 3, wherein the assigned code comprises a login identification code and a password.

6. The system of claim 3 wherein said routing further comprises encapsulating said IP data packets into DOCSIS frames.
