Abstract:
1. A system for setting up a P2P communication group in a cellular system including a base station and terminals, wherein: each of the terminals comprises a location detection unit for detecting a location of a terminal, a location information transmission unit for sending information about the location, detected by the location detection unit, to the base station, a control information reception unit for receiving information about a preliminary P2P communication group set up by the base station based on the location information, and a final group setup unit for setting up a final P2P communication group based on the preliminary P2P communication group; the final group setup unit comprises a group setup signal transmission unit for sending a broadcast signal to target P2P terminals that belong to the preliminary P2P communication group, a group setup signal reception unit for receiving a feedback signal regarding the broadcast signal from the target P2P terminals, a signal measurement unit for detecting channel information and a service type of the feedback signal, and a P2P communication management unit for setting up a final P2P communication group based on the information about the preliminary P2P communication group and the information obtained by the signal measurement unit; and the base station comprises a location information reception unit for receiving location information from the terminals located within a cell, a P2P communication management unit for setting up a preliminary P2P communication group and selecting a P2P communication terminal of the preliminary P2P communication group based on the location information of the terminals, received from the location information reception unit, and a control information transmission unit for sending information about the preliminary P2P communication group and information about the P2P communication terminal to the terminals that belong to the preliminary P2P communication group.
