Patent ID: 8867526

Claim:
A method for providing a service in a communication network, comprising: receiving, by a processor, a register request from a user endpoint device via an access point device; retrieving, by the processor, an access point-address parameter from a contact header in the register request, wherein the access point-address parameter is populated by the access point device when the access point-address parameter is not already populated with an address of another access point device; determining, by the processor, a physical location of the access point device in accordance with the access point-address parameter, wherein the physical location of the access point device comprises a street address; and updating, by the processor, location information for the user endpoint device in accordance with the physical location of the access point device, wherein the location information for the user endpoint device is used to support an emergency service, wherein the user endpoint device is capable of communicating with the access point device over a wireless connection, wherein the updating location information comprises: determining the physical location of the access point device is not the same as a previous address for the user endpoint device; and updating a location information server database for the user endpoint device using the physical location of the access point device when the physical location of the access point device is not the same as the previous address for the user endpoint device.
