Abstract

A method and system of control signaling for a wireless access network includes receiving from a wireless access network a signaling message for a mobile device. The signaling message is in a wireless-specific format. The signaling message is converted to a native format of a call agent to generate a call agent message. The call agent message comprises wireless-specific information of the signaling message.

Claims

1. A method of control signaling for a wireless access network, comprising:

receiving from a wireless access network a signaling message for a mobile device, the signaling message in a wireless-specific format;

converting the signaling message to a native format of a call agent to generate a call agent message, the call agent message comprising wireless-specific information of the signaling message; and

communicating the call agent message to a call agent for processing, whereby the call agent support location updates for the mobile device in the wireless access network, wherein the signaling message comprises a location update message for the mobile device, and wherein the call agent message comprises a session initiation protocol (SIP) message, the SIP message comprising an extension including the wireless-specific information.

2. The method claim 1, wherein the signaling message comprises a call establishment message for the mobile device.

3. The method of claim 1, wherein the signaling message comprises a mobility management message for the mobile device.

4. The method of claim 1, wherein the signaling message comprises a registration message for the mobile device.

5. A system of control signaling for a wireless access network, comprising:

means for receiving from a wireless access network a signaling message for a mobile device, the signaling message in a wireless-specific format;

means for converting the signaling message to a native format of a call agent to generate a call agent message, the call agent message comprising wireless-specific information of the signaling message; and

means for communicating the call agent message to a call agent for processing, whereby the call agent support location updates for the mobile device in the wireless access network, wherein the signaling message comprises a location update message for the mobile device, and wherein the call agent message comprises a session initiation protocol (SIP) message, the SIP message comprising an extension including the wireless-specific information.

6. The system claim 5, wherein the signaling message comprises a call establishment message for the mobile device.

7. The system of claim 5, wherein the signaling message comprises a mobility management message for the mobile device.

8. The system of claim 5, wherein the signaling message comprises a registration message for the mobile device.

9. A system of control signaling for a wireless access network, comprising:

logic encoded in computer readable medium having instructions for execution on a processor; and

to receive from a wireless access network a signaling message for a mobile device in a wireless-specific format;

to convert the signaling message to a native format of a call agent to generate a call agent message, the call agent message comprising wireless-specific information of the signaling message; and

to communicate the call agent message to a call agent for processing, whereby the call agent support location updates for the mobile device in the wireless access network, wherein the signaling message comprises a location update message for the mobile device, and wherein the call agent message comprises a session initiation protocol (SIP) message, the SIP message comprising an extension including the wireless-specific information.

10. The system of claim 9, wherein the signaling message comprises a call establishment message for the mobile device.

11. The system of claim 9, wherein the signaling message comprises a mobility management message for the mobile device.

12. The system of claim 9, wherein the signaling message comprises a registration message for the mobile device.

13. A method for control signaling for a wireless access network, comprising:

receiving from a wireless access network a signaling message in a wireless-specific format, the signaling message comprising location information for a mobile device;

converting the signaling message to a session initiation protocol (SIP) message, the SIP message comprising the location information for the mobile device in an extension; and

communicating the SIP message to a call agent for processing, whereby the call agent support location updates for the mobile device in the wireless access network, wherein the signaling message comprises a location update message for the mobile device, and wherein the call agent message comprises a session initiation protocol (SIP) message, the SIP message comprising an extension including the wireless-specific information.
