Abstract

A method and system for providing services to a communication session anchored to a micro wireless network includes providing at a router of the micro wireless network an interface for communication with a service node of a macro wireless network that is coupled to the micro wireless network. The interface is of a same type as used by a radio access network of the macro wireless network to communicate with the service node. Information associated with the session is communicated between the interface and the service node in a format used by the service node to communicate with the radio access network of the macro wireless network. The macro network provides portability services to the session of the micro wireless network through the interface.

Claims

1. A wireless communication system, comprising:

a macro wireless network comprising a radio access network and a service node, the radio access network operable to communicate information for a wireless session to the service node via a first interface of a type; and

a micro wireless network coupled to the service node of the macro wireless network, the micro wireless network operable to communicate information for a wireless session to the service node via a second interface of the same type as the first interface.

2. The wireless communication system of claim 1, wherein the first and second interfaces comprise a packet control function.

3. The wireless communication system of claim 1, wherein the micro wireless network comprises a wireless local access network (WLAN).

4. The wireless communication system of claim 1, wherein the macro wireless network comprises a code division multiple access (CDMA) wireless network.

5. The wireless communication system of claim 1, wherein the service node comprises a packet data serving node (PDSN).

6. A method for providing services to a communication session anchored to a micro wireless network, comprising:

providing at a router of a micro wireless network an interface for communication with a service node of a macro wireless network coupled to the micro wireless network, the interface of a same type as used by a radio access network of the macro wireless network to communicate with the service node;

communicating information associated with the session between the interface and the service node in a format used by the service node to communicate with the radio access network of the macro wireless network; and

providing macro network services to the session of the micro wireless network through the interface.

7. The method of claim 6, wherein the macro network services comprise locations or services.

8. The method of claim 6, wherein the macro network services comprise push services.

9. The method of claim 6, wherein the macro network services comprise traffic management services.

10. The method of claim 6, wherein the macro network services comprise handoff services.

11. A system for providing services to a communication session anchored to a micro wireless network, comprising:

means for providing at a router of a micro wireless network an interface for communication with a service node of a macro wireless network coupled to the micro wireless network, the interface of a same type as used by a radio access network of the macro wireless network to communicate with the service node;

means for communicating information associated with the session between the interface and the service node in a format used by the service node to communicate with the radio access network of the macro wireless network; and

providing macro network services to the session of the micro wireless network through the interface.

12. The system of claim 11, wherein the macro network services comprise locations or services.

13. The system of claim 11, wherein the macro network services comprise push services.

14. The system of claim 11, wherein the macro network services comprise traffic management services.

15. The system of claim 11, wherein the macro network services comprise handoff services.

16. A system for providing services to a communication session anchored to a micro wireless network, comprising:

logic encoded in media; and

the logic operable to provide at a router of a micro wireless network an interface for communication with a service node of a macro wireless network coupled to the micro wireless network, the interface of a same type as used by a radio access network of the macro wireless network to communicate with the service node, to communicate information associated with the session between the interface and the service node in a format used by the service node to communicate with the radio access network of the macro wireless network and to provide macro network services to the session of the micro wireless network through the interface.

17. The system of claim 16, wherein the macro network services comprise locations or services.

18. The system of claim 16, wherein the macro network services comprise push services.

19. The system of claim 16, wherein the macro network services comprise traffic management services.

20. The system of claim 16, wherein the macro network services comprise handoff services.

21. A method for handover between a macro wireless network and a micro wireless network, comprising:

in response to at least a handover condition for a session anchored to a radio access network of a macro wireless network, initiating establishment of a session with a micro network;

requesting through the micro network and a serving node of the macro network coupled to the micro network authentication for the session; and

in response to at least determining an active session for the mobile node, re-anchoring a virtual path of the active session from a radio access network of the macro wireless network to an access point of the micro wireless network.
