Abstract

Embodiments of the claimed subject matter provide a method and apparatus for providing multicast/broadcast information to obstructed user equipment. Some embodiments of the apparatus include a gateway configured for communicative coupling to an antenna. The gateway is configurable to establish a first broadcast/multicast session for receiving at least one broadcast or multicast service associated with user equipment and establish a second session for providing information received in the first broadcast/multicast session to the user equipment. Some embodiments include user equipment are configurable to provide a request to receive a broadcast service or a multicast service from a gateway that receives the broadcast or multicast service(s) via a first broadcast/multicast session. Some embodiments of the user equipment are also configurable to establish a second session with the gateway for receiving the broadcast or multicast service(s).

First claim

What is claimed:

1. An apparatus, comprising:
a gateway configured for communicative coupling to an antenna, wherein the gateway is configured to establish a first broadcast/multicast session with a base station for wirelessly receiving at least one broadcast or multicast service, wherein the at least one broadcast or multicast service is for wireless reception by user equipment using a second broadcast/multicast session established between the user equipment and the base station, wherein the second broadcast/multicast session bypasses the gateway, wherein the gateway is configured to establish a communication session for providing information received in the first broadcast/multicast session to the user equipment, and wherein the first broadcast/multicast session is terminated at the gateway; and
a first session manager for the gateway, wherein the first session manager is configured to provide signaling to establish the first broadcast/multicast session in response to the gateway determining that the user equipment has attached to the gateway and the first session manager identifying the at least one broadcast or multicast service associated with user equipment.

2. The apparatus of claim 1 , wherein the gateway is configured to establish both the first broadcast/multicast session and the communication session in response to receipt of a request from the user equipment.

3. The apparatus of claim 1 , wherein the gateway is configured to establish both the first broadcast/multicast session and the communication session in response to receipt of an indication that the user equipment has moved from an external location to an internal location.

4. The apparatus of claim 1 , wherein the gateway is configured to establish the first broadcast/multicast session and the communication session in response to determining that the user equipment is within a predetermined distance of the gateway.

5. The apparatus of claim 1 , comprising the antenna, wherein the antenna is configured for coupling to an exterior surface of a building or vehicle, and wherein the gateway is configured for coupling to an interior surface of the building or the vehicle.

6. The apparatus of claim 5 , wherein the gateway is configured to establish the first broadcast/multicast session and the communication session in response to determining that the user equipment is within the building or the vehicle.

7. The apparatus of claim 1 , wherein the first session manager is configured to communicate with a second session manager implemented in the user equipment, and wherein the gateway is configured to establish the first broadcast/multicast session in response to the signaling provided by the first session manager in response to receipt of a request from the second session manager.

8. The apparatus of claim 1 , wherein establishing the first broadcast/multicast session comprises authenticating the gateway to a broadcast multicast service center (BM-SC), and wherein establishing the communication session comprises authenticating the user equipment to the gateway.

9. The apparatus of claim 1 , wherein the gateway is configured to provide a request for a new multicast service to be provided using the first broadcast/multicast session in response to receiving a request for the new multicast service from the user equipment, and wherein the gateway is configured to provide the new multicast service to the user equipment using the communication session.

10. The apparatus of claim 1 , wherein the gateway is configured to tear down the first broadcast/multicast session and the communication session in response to receipt of a request from the user equipment.

11. A method, comprising:
establishing, at a gateway, a first broadcast/multicast session with a base station for wirelessly receiving at least one broadcast or multicast service, wherein the at least one broadcast or multicast service is for wireless reception by user equipment using a second broadcast/multicast session established between the user equipment and the base station, wherein the first broadcast/multicast session is terminated at the gateway, and wherein the second broadcast/multicast session bypasses the gateway;
establishing, at the gateway, a communication session for providing information received in the first broadcast/multicast session to the user equipment;
providing the signaling to establish the first broadcast/multicast session in response to a first session manager determining the user equipment has attached to the gateway; and
identifying the at least one multicast/broadcast service provided to the user equipment using the second broadcast/multicast session.

12. The method of claim 1 , comprising receiving, at the gateway, a request from the user equipment to receive the at least one broadcast or multicast service and wherein said establishing the first broadcast/multicast session and said establishing the communication session are performed in response to said receiving the request.

13. The method of claim 11 , wherein said establishing the first broadcast/multicast session and said establishing the communication session are performed in response to the user equipment has moved from an external location to an internal location, and the method comprising receiving an indication that the user equipment previously established the second broadcast/multicast session for wirelessly receiving the at least one broadcast or multicast service at the external location.

14. The method of claim 11 , comprising determining, at the gateway, a distance between the user equipment and the gateway, and wherein said establishing the first broadcast/multicast session and said establishing the communication session are performed in response to determining that the distance is less than a threshold distance.

15. The method of claim 14 , wherein the gateway is configured for coupling to an interior surface of a building or a vehicle, and wherein said establishing the first broadcast/multicast session and said establishing the communication session comprises establishing the first broadcast/multicast session and the communication session respectively in response to determining that the user equipment is within the building or the vehicle.

16. The method of claim 11 , comprising establishing the first broadcast/multicast session in response to the signaling provided by the first session manager for the gateway in response to a request from a second session manager implemented in the user equipment.

17. The method of claim 11 , wherein establishing the first broadcast/multicast session comprises authenticating the gateway to a broadcast multicast service center (BM-SC), and wherein establishing the communication session comprises authenticating the user equipment to the gateway.

18. The method of claim 11 , comprising:
providing a request for a new multicast service to be provided using the first broadcast/multicast session in response to receiving a request for the new multicast service from the user equipment, and
providing the new multicast service to the user equipment using a third session.

19. The method of claim 11 , comprising tearing down the first broadcast/multicast session and the communication session in response to a request from the user equipment.

20. User equipment including a processor configured to:
provide a request to receive at least one of a broadcast or multicast service from a gateway that terminates a first broadcast/multicast session used to wirelessly provide said at least one of the broadcast or
