Method, system and apparatus for verifying validity of location information in a packet-based network
First Claim
1. A method for determining if location information associated with an endpoint in a packet-switched network is valid, said location information having been stored in a memory, the method comprising:
- obtaining an access device identifier associated with an access device responsible for handling a communication session between said endpoint and said packet-switched network, said access device being a network entity distinct from said endpoint;
comparing said access device identifier with a last known access device identifier associated with said endpoint;
based on said comparing, determining if said location information is valid.

Abstract
According to embodiments of the present invention, there are provided a method, system and apparatus for determining validity of location information in a packet-switched network. A method for determining if location information associated with an endpoint in a packet-switched network is valid, the location information having been stored in a memory, comprises obtaining an access device identifier associated with an access device responsible for handling a communication session between the endpoint and the packet-switched network. The access device identifier is then compared with a last known access device identifier associated with the endpoint to enable determining if the location information is valid.

24. A system for determining if location information associated with an endpoint in a packet-switched network is valid, said location information having been stored in a memory, the system comprising:
-
a network entity; and a storage medium coupled to the network entity storing codes that when executed by the network entity to; obtain an access device identifier associated with an access device responsible for handling a communication session between said endpoint and said packet-switched network, said access device being a network entity distinct from said endpoint; compare said access device identifier with a last known access device identifier associated with said endpoint; determine if said location information is valid based on the comparison. - View Dependent Claims (25, 26, 27, 28)
