Abstract
An apparatus, system, and method for managing geographical location information of a portable communication device by determining and storing the geographic location information while registered on a cellular communication system in response to detecting an available wireless local area network (WLAN) system. When the portable communication device is communicating on the cellular communication system and a WLAN access point is detected, a location determination procedure is performed and the resulting geographical location information is stored at the portable communication device. When the portable communication device is communicating with a wireless access point of a WLAN system, and a second access point is detected, the portable communication device registers to the cellular communication network, if not already registered, and performs the geographical location determination procedure. Geographical location information is transmitted to a public safety answering point (PSAP) or network entity when an emergency call is executed.
