Abstract

A mobile terminal associated with a first wireless communication network includes a transceiver that sends a service request message to a first wireless communication network element via a second wireless communications network. The request message requests a service from the second wireless communications network. The transceiver receives service from the first wireless communication network without requiring the mobile terminal to perform an access control procedure with the second wireless communications network.

Claims

1. A mobile terminal associated with a first wireless communication network, the mobile terminal comprising:

a transceiver configured to;

send a service request message to a first wireless communication network element via a second wireless communications network, the request message requesting a service from the second wireless communications network, and

receive service from the first wireless communication network without requiring the mobile terminal to perform an access control procedure with the second wireless communications network.

2. The mobile terminal in claim 1, wherein the service includes address information for the mobile terminal.

3. The mobile terminal in claim 2, wherein when the mobile terminal is engaged in an active session prior to sending the service request message, the address information includes a same address previously allocated to the mobile terminal for the active session.

4. The mobile terminal in claim 2, wherein the service request message includes service from the second wireless communications network for multiple communications sessions, and wherein the address information includes multiple addresses for the mobile terminal for the multiple communications sessions.

5. The mobile terminal in claim 1, wherein before sending the service request message, the mobile terminal is configured to perform association and authentication messaging with the second wireless communications network.

6. The mobile terminal in claim 5, wherein the service request message and the address information are protected using security association information provided during the association and authentication messaging.

7. The mobile terminal in claim 1, wherein the service request message includes a mobile terminal identifier useable by the first wireless communication network element to retrieve subscription information associated with the mobile terminal.

8. The mobile terminal in claim 1, wherein the transceiver is configured to receive from the first wireless communications network address information for the mobile terminal.

9. The mobile terminal in claim 8, wherein the address information is not local to the second wireless communications network, and wherein the transceiver is configured to send a tunnel setup request message via the second wireless communications network, the tunnel setup request message including the service request identifier for accessing the requested service and a mobile terminal identifier.

10. The mobile terminal in claim 9, wherein the mobile terminal is configured to request and receive the address information and to receive information confirming setup of the requested tunnel within one roundtrip message exchange with the first wireless communication network element.

11. The mobile terminal in claim 9, wherein the transceiver is configured to:

send an aggregate service request message to the first wireless communication network element via the second wireless communications network that includes multiple different service requests; and

receive information corresponding to different tunnels for different service sessions associated with the different services.

12. A method for a mobile terminal associated with a first wireless communication network, the method comprising:

sending, by the mobile terminal, a service request message to a first wireless communication network element via a second wireless communications network, the request message requesting a service from the second wireless communications,

receiving, by the mobile terminal, service from the first wireless communication network without requiring the mobile terminal to perform an access control procedure with the second wireless communications network.

13. The method in claim 12, wherein the service includes address information for the mobile terminal.

14. The method in claim 13, wherein when the mobile terminal is engaged in an active session prior to sending the service request message, the received address information includes a same address previously allocated to the mobile terminal for the active session.

15. The method in claim 13, wherein the service request message includes services from the second wireless communications network for multiple communications sessions, and wherein the address information includes multiple addresses for the mobile terminal for the multiple communications sessions.

16. The method in claim 12, wherein before sending the service request message, the method includes performing association and authentication messaging with the second wireless communications network.

17. The method in claim 16, wherein the service request message and the address information are protected using security association information provided during the association and authentication messaging.

18. The method in claim 12, wherein the service request message includes a mobile terminal identifier useable by the first wireless communication network element to retrieve subscription information associated with the mobile terminal.

19. The method in claim 12, wherein the address information is not local to the second wireless communications network, and wherein the method further comprises sending a tunnel setup request message via the second wireless communications network, the tunnel setup request message including the service request identifier for accessing the requested service and a mobile terminal identifier.

20. The method in claim 19, further comprising:

sending an aggregate service request message to the first wireless communication network element via the second wireless communications network that includes multiple different service requests, and

receiving information corresponding to different tunnels for different service sessions associated with the different services.
