Method and apparatus for proximity-based service between more than two operators
First Claim
1. A method of setting up a Proximity-based Service (ProSe) connection by a ProSe-enabled user equipment (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 by using a specific radio resource which is available to ProSe-enabled UEs of a second MNO and a third MNO;
checking whether acknowledgement information regarding the first message is received from one or more ProSe-enabled UEs of the second MNO or the third MNO by using the first radio resource;
broadcasting a second message including second resource allocation information for a second radio resource of the first MNO by using the specific radio resource when the acknowledgement information regarding the first message is received by using the first radio resource;
receiving one or more ProSe connection requests as responses to the second message from the one or more ProSe-enabled UEs of the second MNO or the third MNO by using the second radio resource; and
broadcasting the second message by using the specific radio resource again, if any collision between the second MNO and the third MNO is detected from the one or more ProSe connection requests.

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.

6. A Proximity-based Service (ProSe)-enabled user equipment (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 by using a specific radio resource which is available to ProSe-enabled UEs of a second MNO and a third MNO, check whether acknowledgement information regarding the first message is received from one or more ProSe-enabled UEs of the second MNO or the third MNO by using the first radio resource, broadcast a second message including second resource allocation information for a second radio resource of the first MNO by using the specific radio resource when the acknowledgement information regarding the first message is received by using the first radio resource, receive one or more ProSe connection requests as responses to the second message from the one or more ProSe-enabled UEs of the second MNO or the third MNO by using the second radio resource, and broadcast the second message by using the specific radio resource again, if any collision between the second MNO and the third MNO is detected from the one or more ProSe connection requests. - View Dependent Claims (7, 8, 9, 10)
