Abstract

The present invention is directed to a method and an apparatus for use in a wireless communication system. Specifically, the present invention is directed to a method of setting up a ProSe connection by a ProSe-enabled UE of a first MNO in a cellular communication system and an apparatus therefore, in which the method comprises: broadcasting a first message including first resource allocation information for a first radio resource of the first MNO, wherein the first message is broadcast using a specific radio resource that is available to ProSe-enabled UEs of a second MNO; and receiving acknowledgement information regarding the first message from one or more ProSe-enabled UEs of the second MNO by using the first radio resource of the first MNO.

Claims

1. A method of setting up a Proximity-based Service (ProSe) connection by a ProSe-enabled UE of a first Mobile Network Operator (MNO) in a cellular communication system, the method comprising:

broadcasting a first message including first resource allocation information for a first radio resource of the first MNO, wherein the first message is broadcast using a specific radio resource that is available to ProSe-enabled UEs of a second MNO; and

receiving acknowledgement information regarding the first message from one or more ProSe-enabled UEs of the second MNO by using the first radio resource of the first MNO.

2. The method of claim 1, wherein the first message further includes at least one of a maximum number of trials for the acknowledgement information and a back-off configuration for the acknowledgement information.

3. The method of claim 1, wherein if no collision is detected from the received acknowledgement information, further comprising:

broadcasting a second message including second resource allocation information for a second radio resource of the first MNO by using the specific radio resource; and

receiving a ProSe connection request from the one or more ProSe-enabled UEs of the second MNO by using the second radio resource of the first MNO.

4. The method of claim 3, wherein the second message further includes identity information for a sender of the second message and identity information for the second MNO.

5. The method of claim 4, wherein the second message further includes at least one of a maximum number of trials for the ProSe connection request and a back-off configuration for the ProSe connection request.

6. The method of claim 1, wherein the first MNO is different from the second MNO.

7. A ProSe-enabled UE of a first Mobile Network Operator (MNO) configured to set up a ProSe connection in a wireless communication system, the ProSe-enabled UE of the first MNO comprising:

a radio frequency (RF) unit; and

a processor, wherein the processor is configured to;

broadcast a first message including first resource allocation information for a first radio resource of the first MNO, wherein the first message is broadcast using a specific radio resource that is available to ProSe-enabled UEs of a second MNO, and

receive acknowledgement information regarding the first message from one or more ProSe-enabled UEs of the second MNO by using the first radio resource of the first MNO.

8. The ProSe-enabled UE of the first MNO of claim 7, wherein the first message further includes at least one of a maximum number of trials for the acknowledgement information and a back-off configuration for the acknowledgement information.

9. The ProSe-enabled UE of the first MNO of claim 7, wherein if no collision is detected from the received acknowledgement information, further processor is further configured to:

broadcast a second message including second resource allocation information for a second radio resource of the first MNO by using the specific radio resource; and

receive a ProSe connection request from the one or more ProSe-enabled UEs of the second MNO by using the second radio resource of the first MNO.

10. The ProSe-enabled UE of the first MNO of claim 9, wherein the second message further includes identity information for a sender of the second message and identity information for the second MNO.

11. The ProSe-enabled UE of the first MNO of claim 10, wherein the second message further includes at least one of a maximum number of trials for the ProSe connection request and a back-off configuration for the ProSe connection request.

12. The ProSe-enabled UE of the first MNO of claim 7, wherein the first MNO is different from the second MNO.
