Abstract

A method for communicating between a network and a dual receiver UE includes receiving first signaling from a first network node at a first frequency, and receiving second signaling via a PtM control channel from a second network node at a second frequency. The method further includes receiving a request from the second network node at the second frequency, such that the request is carried on the PtM control channel, and transmitting to the first network node a response to the request from the second network node. An alternative method includes receiving communications from a first network node, and identifying that the first network node lacks uplink capabilities. This method may further include identifying that the first network node provides a MBMS service, and receiving the MBMS service from the first network node despite the identification of the lack of uplink capabilities.

Claims

1. A method for communicating between a network and a dual receiver user equipment (UE), said method comprising:

receiving first signaling from a first network node at a first frequency;

receiving second signaling via a point-to-multipoint (PtM) control channel from a second network node at a second frequency, substantially simultaneously with receiving said first signaling from said first network node at said first frequency;

receiving a request from said second network node at said second frequency, wherein said request is carried on said PtM control channel; and

transmitting to said first network node a response to said request from said second network node;

receiving transmission permission from either of said second network node or said first network node, wherein said transmission permission causes said transmitting of said response to said first network node; and

receiving a frequency conversion message from said first network node, wherein said message allows said UE to attempt to reselect a third network node transmitting on said second frequency, wherein said transmission permission causes said UE to disregard said message such that said UE does not perform said attempt to reselect,

wherein said response is not transmitted to said second network node, and

wherein said first network node and said second network node are separately implemented in distinct base stations.

2. The method according to claim 1, further comprising:

receiving a list of at least one different network node which transmits at said second frequency and which provides cell coverage which overlaps at least a portion of cell coverage provided by said first network node.

3. The method according to claim 1, further comprising:

receiving at least one identity from said first network node, wherein said at least one identity identifies said second network node.

4. The method according to claim 1, wherein said transmission permission is received from said second network node and comprises a list of network nodes to which said response can be transmitted.

5. The method according to claim 1, wherein said transmission permission is received from said first network node and comprises a list of network nodes from which said request has been received.

6. The method according to claim 1, wherein said response comprises at least one of a service identifier which identifies a service associated with said user equipment (UE), a frequency identifier which identifies said second frequency, and a cell identifier which identifies said second network node.

7. The method according to claim 1, wherein said response comprises one of an RRC connection request and a cell update.

8. The method according to claim 1, wherein said response comprises a multimedia broadcast/multicast service (MBMS) modification request.

9. The method according to claim 1, wherein said request comprises a counting request.

10. The method according to claim 1, wherein said request comprises a point-to-point establishment request.

11. The method according to claim 1, wherein said point-to-multipoint (PtM) control channel comprises a multimedia broadcast/multicast service (MBMS) point-to-multipoint control channel.

12. A method for communicating between a network and a dual receiver user equipment (UE), said method comprising:

communicating first signaling from a first network node at a first frequency;

communicating second signaling via a point-to-multipoint (PtM) control channel from a second network node at a second frequency, substantially simultaneously with communicating said first signaling from said first network node at said first frequency;

communicating a request from said second network node at said second frequency, wherein said request is carried on said PtM control channel;

receiving at said first network node a response to said request from said second network node;

communicating transmission permission from either of said second network node or said first network node, wherein said transmission permission causes transmitting of said response to said first network node; and

communicating a frequency conversion message from said first network node, wherein said message allows said UE to attempt to reselect a third network node transmitting on said second frequency, wherein said transmission permission causes said UE to disregard said message such that said UE does not perform said attempt to reselect,

wherein said response is not received at said second network node, and

wherein said first network node and said second network node are separately implemented in distinct base stations.

13. The method according to claim 12, further comprising:

communicating a list of at least one different network node which transmits at said second frequency and which provides cell coverage which overlaps at least a portion of cell coverage provided by said first network node.

14. The method according to claim 12, further comprising:

communicating at least one identity from said first network node, wherein said at least one identity identifies said second network node.

15. The method according to claim 12, wherein said transmission permission is communicated from said second network node and comprises a list of network nodes to which said response can be transmitted.

16. The method according to claim 12, wherein said transmission permission is communicated from said first network node and comprises a list of network nodes from which said request has been received.

17. The method according to claim 12, wherein said response comprises at least one of a service identifier which identifies a service associated with said user equipment (UE), a frequency identifier which identifies said second frequency, and a cell identifier which identifies said second network node.

18. The method according to claim 12, wherein said response comprises one of an RRC connection request and a cell update.

19. The method according to claim 12, wherein said response comprises a multimedia broadcast/multicast service (MBMS) modification request.

20. The method according to claim 12, wherein said request comprises a counting request.

21. The method according to claim 12, wherein said request comprises a point-to-point establishment request.

22. The method according to claim 12, wherein said point-to-multipoint (PtM) control channel comprises a multimedia broadcast/multicast service (MBMS) point-to-multipoint control channel.
