Abstract

Method and apparatus for dynamic provisioning of a Mobile Station (MS) to provide server configuration information. In one embodiment, a home network determines whether to use the visited local network or the home network. An indicator selecting the associated server is transmitted. The server is for session control, such as Session Initiation Protocol (SIP) control of voice over Internet Protocol (IP) communications.

Claims

1. A method for dynamic provisioning of a mobile station in a wireless communication system supporting Internet Protocol (IP) communications, the method comprising:

initiating access authentication with a visited network;

receiving a Dynamic Host Configuration Protocol (DHCP) capability indicator for the visited network;

receiving server configuration information for the visited network; and

processing a communication via the server of the visited network.

2. The method as in claim 1, wherein the server is a proxy Session Initiation Protocol (SIP) server.

3. The method as in claim 2, wherein the server is a Proxy-Call State Control Function (P-CSCF).

4. The method as in claim 1, further comprising:

transmitting an access request message to the visited network.

5. The method as in claim 4, wherein the DHCP capability indicator is a one bit field.

6. The method as in claim 1, further comprising:

receiving a Proxy-Call State Control Function (P-CSCF) capability indicator.

7. A remote station apparatus comprising:

a control processor for executing computer-readable instructions;

memory storage device for storing computer-readable instructions for;

initiating access authentication with a visited network;

receiving a Dynamic Host Configuration Protocol (DHCP) capability indicator for the visited network;

receiving server configuration information for the visited network; and

processing a communication via the server of the visited network.

8. A remote station, comprising:

means initiating access authentication with a visited network;

means for receiving a Dynamic Host Configuration Protocol (DHCP) capability indicator for the visited network;

means for receiving server configuration information for the visited network; and

means for processing a communication via the server of the visited network.

9. A method for a home network in a wireless communication system supporting Internet Protocol (IP), comprising:

determining a server for session processing; and

sending an indicator identifying the server.

10. The method as in claim 9, wherein the server is a Proxy-Call State Control Function (P-CSCF).
