Abstract

A wireless communications device and network having the ability to detect when a call session with a public service access point (PSAP) has not transferred location information for the wireless device to the PSAP. In on embodiment, the detection means includes a location request timer (LRT), which is started when the emergency call is initiated. If the LRT expires before a request for location information is received by the wireless communications device, the wireless device concludes that the PSAP does not have the location information. In another embodiment the wireless network determines the PSAP does not have location information without a timer. The location information is then presented to a caller on the wireless device, which allows the caller of the wireless device to relay the information to a human PSAP operator. The location information may also be provided to a human PSAP operator in a automated manner.
