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:

receiving, by a mobile station, a control message containing an indicator of presence of a first access network that is capable of interworking with a second access network, wherein the first access network operates according to a first protocol, and the second access network operates according to a second, different protocol; and

in response to receiving the indicator, performing, by the mobile station, a procedure to establish a personality for the mobile station that specifies a configuration to allow the mobile station to use features of the first access network that enable interworking with the second access network.

2. The method of claim 1, further comprising:

transitioning, by the mobile station, from a third access network to the first access network, wherein the third access network is according to a third protocol that does not support interworking with the second access network, and wherein receiving the indicator is after the transitioning.

3. The method of claim 1, wherein the control message further contains additional indicators of presence of other first access networks capable of interworking with the second access network.

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

5. The method of claim 4, wherein the broadcast overhead message is one of a QuickConfig message and a SectorParameters message.

6. The method of claim 1, wherein the first access network is an eHRPD (Evolved High Rate Packet Data) access network.

7. The method of claim 6, wherein the second access network is an EUTRA (Evolved Universal Terrestrial Radio Access) access network.

8. 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.

9. A method comprising:

sending, by a first access network to a mobile station, a control message containing an indicator of presence of a particular access network that is capable of interworking with a second access network, wherein the particular access network operates according to a first protocol, and the second access network operates according to a second, different protocol,

wherein the indicator allows the mobile station to establish a personality that allows the mobile station to use features of the particular access network that enable interworking with the second access network.

10. The method of claim 9, wherein the particular access network is the first access network.

11. The method of claim 10, further comprising the first access network cooperating with the mobile station to establish the personality.

12. The method of claim 9, wherein the particular access network is different from the first access network.

13. The method of claim 9, wherein sending the control message comprises broadcasting an overhead message.

14. The method of claim 9, wherein the first protocol is an eHRPD (Evolved High Rate Packet Data) protocol.

15. The method of claim 9, wherein the second protocol is an EUTRA (Evolved Universal Terrestrial Radio Access) protocol.

16. The method of claim 9, wherein the personality defines protocol types and associated attribute values used for communication between the mobile station and the particular access network.

17. A mobile station, comprising:

an interface to a wireless link; and

at least one processor configured to;

receive a control message containing an indicator of presence of a first access network that is capable of interworking with a second access network, wherein the first access network operates according to a first protocol, and the second access network operates according to a second, different protocol; and

in response to receiving the indicator, perform a procedure to establish a personality for the mobile station that specifies a configuration to allow the mobile station to use features of the first access network that enable interworking with the second access network.

18. The mobile station of claim 17, wherein receipt of the control message is after the mobile station has transitioned from a third access network to the first access network, and wherein the third access network is according to a third protocol that does not support interworking with the second access network.

19. The mobile station of claim 17, wherein the first access network is an eHRPD (Evolved High Rate Packet Data) access network.

20. The mobile station of claim 17, wherein the second access network is an EUTRA (Evolved Universal Terrestrial Radio Access) access network.

21. A base station comprising:

an interface to a wireless link; and

at least one processor configured to;

send, to a mobile station, a control message containing an indicator of presence of a particular access network that is capable of interworking with a second access network, wherein the particular access network operates according to a first protocol, and the second access network operates according to a second, different protocol,

wherein the indicator allows the mobile station to establish a personality that allows the mobile station to use features of the particular access network that enable interworking with the second access network.

22. The base station of claim 21, wherein the base station is part of the particular access network.

23. The base station of claim 21, wherein the particular access network is an eHRPD (Evolved High Rate Packet Data) access network, and the second access network is an EUTRA (Evolved Universal Terrestrial Radio Access) network.
