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.
