1. A system, comprising:
- a 911 Service Provider device having a processor and configured to store an address of a fixed wireless device;
a location validation device configured to;
obtain fine position information determined by using Global Positioning System information and cell tower trilateration information for the fixed wireless device after an initial activation of the fixed wireless device and prior to receiving any emergency communications from the fixed wireless device; and
validate the address of the fixed wireless device stored in the 911 Service provider device based on the obtained fine position information after the initial activation of the fixed wireless device and prior to receiving any emergency communications from the fixed wireless device;
a mobile switching center (MSC) configured to receive, from the fixed wireless device, an emergency communication over a wireless network;
a mobile positioning center (MPC) device configured to provide an emergency services routing key (ESRK) for the emergency communication to the MSC; and
a dynamic automatic location identification (DALI) device configured to request resolution of a position of the fixed wireless device in connection with the emergency communication;
wherein the MSC is further configured to deliver the emergency communication to a public safety answering point (PSAP) using the ESRK; and
wherein the DALI device is further configured to;
receive, from the PSAP, a request for the address of the fixed wireless device, wherein the request for the address includes the ESRK;
obtain the address of the fixed wireless device stored in the 911 Service Provider device; and
transmit the obtained address of the fixed wireless device to the PSAP.

Abstract
A previously obtained location of a fixed wireless device is stored and available for processing of a call or the like from the device when a location determination may be desirable. In some circumstances, the previously obtained location of the fixed wireless device may be retrieved to provide information to a public-safety answering point (PSAP) during handling of an emergency call initiated by the fixed wireless device over a wireless network.
