Abstract

An exemplary method of facilitating communications involving a Femto base station (F-BS) includes establishing an association between the F-BS and a wireline backhaul resource used by the F-BS for initiating at least one traffic flow of the F-BS for a wireless communication session. Quality of service information for the wireless communication session is determined. The determined quality of service information allows for determining a corresponding quality of service requirement of the backhaul resource in the packet transport network. The established association is used for identifying the corresponding quality of service to the F-BS on the wireline backhaul resource of the established association during the wireless communication session.

Claims

1. A method of facilitating communications involving a Femto base station (F-BS), comprising the steps of:

establishing an association between the F-BS, and a wireline backhaul resource used by the F-BS for initiating at least one traffic flow of the F-BS for a wireless communication session;

determining quality of service information for the wireless communication session;

determining a corresponding quality of service requirement of the wireline backhaul resource based on the determined quality of service information; and

using the established association for providing the corresponding quality of service to the F-BS on the wireline backhaul resource of the established association during the wireless communication session.

2. The method of claim 1, comprising releasing the wireline backhaul resource upon termination of the wireless communication session.

3. The method of claim 1, wherein establishing the association comprises receiving a registration request from the F-BS at a gateway;

associating an identifier of the F-BS with the wireline backhaul resource;

receiving a registration message regarding a mobile station provided by the F-BS to the gateway;

associating an identifier of the mobile station with the associated F-BS identifier and the wireline backhaul resource.

4. The method of claim 3, wherein the gateway comprises a Femto gateway that interfaces with an anchor point of a wireless communication network that facilitates the wireless communication session.

5. The method of claim 1, comprising

receiving a request for the corresponding wireline quality of service;

and

granting the received request if at least one of a service level agreement or a network policy accommodate the received request.

6. The method of claim 5, comprising mapping quality of service parameters of the determined quality of service information for the wireless communication session to quality of service parameters useful for the wireline quality of service.

7. The method of claim 1, comprising using an Internet Protocol address of the F-BS to identify the wireline backhaul resource in the established association.

8. The method of claim 1, comprising

communicating between a wireless resource manager and a wireline resource manager for determining the corresponding quality of service requirement of the wireline backhaul resource.

9. The method of claim 8, comprising

checking a subscription profile of the F-BS or a mobile station registered with the F-BS for determining an allowable quality of service.

10. The method of claim 1, wherein the wireline backhaul resource is part of a packet transport network.
