Method and system for peer-to-peer communication in a communication system

摘要

A method and system for establishing a P2P communication connection between mobile stations in a cellular communication system are provided, in which a first mobile station transmits a first request message requesting setup of a P2P communication connection to a base station, receives a neighbor table including information about mobile stations capable of P2P communications with the first mobile station from the base station, selects a second mobile station with which to establish the P2P communication connection using the neighbor table, and establishes the P2P communication connection with the second mobile station.

1. A method for establishing a Peer-to-Peer (P2P) communication connection between mobile stations in a cellular communication system, comprising:
transmitting a ready message to a plurality of second mobile stations within a service area of the base station to transition the plurality of second mobile stations to P2P active mode upon receipt of a request message requesting setup of a P2P communication connection from a first mobile station; receiving, from at least one second mobile station among the plurality of second mobile stations, a response message including mobile station information about each of the at least one second mobile station that transitioned to the P2P active mode among the plurality of second mobile stations; generating a neighbor table using the mobile station information about each of the at least one second mobile station, the mobile station information comprising distances between the first mobile station and the at least one second mobile station that transitioned to the P2P active mode; and transmitting the neighbor table to the first mobile station that transmitted the request message, wherein the P2P communication connection is established between the first mobile station and one or more second mobile stations which the first mobile station selects among the at least one second mobile station based on the neighbor table.
