Abstract

A mobile station receives a control message containing an indicator of presence of a first access network that operates according to a first protocol that is capable of interworking with a second access network that operates according to a second, different protocol. In response to receiving the indicator, the mobile station performs a procedure to establish a personality for the mobile station that specifies the configuration to allow the mobile station to use features of the first access network that enable interworking with the second access network.

Claims

1. A method comprising:

by a mobile station,

receiving a control message containing an indicator of a first access network that is interoperable with a second access network, wherein the first access network has a first protocol, and the second access network has a second protocol; and

performing a procedure to establish a personality for the mobile station, in response to receiving the control message, wherein the personality specifies a configuration allowing the mobile station to use features of the first access network that enable interworking with the second access network, and wherein the performing the procedure comprises negotiating the personality for the mobile station.

2. The method of claim 1, further comprising:

transitioning, prior to receiving the control message, from a third access network to the first access network, wherein the third access network is not interoperable with the second access network.

3. The method of claim 1, wherein the control message further contains additional indicators of additional access networks that are interoperable with the second access network, wherein each of the additional access networks has the first protocol.

4. The method of claim 1, wherein receiving the control message comprises receiving a broadcast overhead message.

5. The method of claim 1, wherein the personality defines protocol types and associated attribute values used for communication between the mobile station and the first access network.

6. The method of claim 1, wherein the procedure to establish the personality comprises a session configuration procedure with the first access network.

7. A method comprising:

by a base station of an access network,

sending, to a mobile station, a control message containing an indicator of a first access network that is interoperable with a second access network, wherein the first access network has a first protocol, and the second access network has a second protocol; and

establishing a personality for the mobile station, wherein the personality specifies a configuration allowing the mobile station to use features of the first access network that enable interworking with the second access network, and wherein the establishing comprises negotiating the personality for the mobile station.

8. The method of claim 7, wherein the access network is the first access network.

9. The method of claim 7, further comprising the first access network cooperating with the mobile station to establish the personality.

10. The method of claim 7, wherein the access network is different from the first access network.

11. The method of claim 7, wherein sending the control message comprises broadcasting an overhead message.

12. The method of claim 7, wherein the personality defines protocol types and associated attribute values used for communication between the mobile station and the access network.

13. The method of claim 7, wherein establishing the personality comprises a session configuration procedure with the access network.

14. A mobile station, comprising:

an interface to a wireless link; and

at least one processor coupled to the interface and configured to;

receive a control message containing an indicator of a first access network that is interoperable with a second access network, wherein the first access network has a first protocol, and the second access network has a second protocol; and

perform a procedure to establish a personality for the mobile station, in response to receiving the control message, wherein the personality specifies a configuration allowing the mobile station to use features of the first access network that enable interworking with the second access network, and wherein to perform the procedure, the at least one processor is further configured to negotiate the personality for the mobile station.

15. The mobile station of claim 14, wherein the at least one processor is further configured to:

transition, prior to receiving the control message, from a third access network to the first access network, wherein the third access network is not interoperable with the second access network.

16. The mobile station of claim 14, wherein the control message further contains additional indicators of additional access networks that are interoperable with the second access network, wherein each of the additional access networks has the first protocol.

17. The mobile station of claim 14, wherein the control message is a broadcast overhead message.

18. The mobile station of claim 14, wherein the personality defines protocol types and associated attribute values used for communication between the mobile station and the first access network.

19. The mobile station of claim 14, wherein to perform the procedure, the at least one processor is further configured to:

cooperate with the first access network to establish the personality.

20. The mobile station of claim 14, wherein the procedure to establish the personality comprises a session configuration procedure with the first access network.
