Abstract

See full text

A multi-mode mobile station is able to wirelessly communicate with a wireless wide area network (WWAN) and with a wireless local area network (WLAN). The WLAN includes a “virtual” visitor location register (VVLR) for storing information about multi-mode mobile stations being served by the WLAN. The VVLR communicates with a home location register (HLR) in the WWAN in order to facilitate roaming between the WWAN and WLAN by the multi-mode mobile station.
