发明名称 Method and apparatus for providing mobility for a voice over internet protocol service
摘要 A method and an apparatus for providing mobility for a Voice over Internet Protocol Service (VoIP) provided on packet networks are disclosed. For example, the method receives a register request from a user endpoint device and retrieves an Access Point-address parameter from a contact header in the register request. The method then determines a physical location of an access point device in accordance with the Access Point-address parameter and updates location information for the user endpoint device in accordance with the physical location of the access point device.

主权项 1. 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; andupdating 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.
