ABSTRACT:
A mobile wireless terminal, upon transitioning from a wireless telephony network to a wireless Local Area Network (LAN), seeks identification by sending the same identity information used for identification in the wireless telephony network. Upon receipt of the identity information, a wireless LAN Access Server in the wireless telephony network identifies a Serving General Packet Radio Service Serving Node (SGSN) that had last served the wireless terminal in the wireless telephony network prior to transition. The wireless LAN Access Server forwards the identity information to the SGSN, which, in turn, provides an identification response for validating the terminal.
