Communication Method And Apparatus For Providing Real-Time Wireless Bulletin Board System

A communication method to be executed by a UE supporting P2P communication mode, comprising the steps of:

• (A) sending a request to a network system for establishing a real-time wireless BBS among a group of UEs including the UE, wherein the request includes identification information of other UEs among the group of UEs;
• (B) receiving radio resources allocated according to the request from the network system;
• (C) exchanging information with the other UEs via direct links for P2P communication, by using the radio resources.

A communication method for a wireless communication network supporting P2P communication mode to be executed by a UE, comprising the steps of:

• receiving a paging message, which is sent out according to a request for establishing a real-time wireless BBS among a group of UEs, from a network system;
• sending a paging response message to the network system, wherein the paging response message comprises at least one of location information of the UE, P2P capability indication information and information about whether establishment of the real-time wireless BBS is allowed.

A network system, comprising:

• a receiving unit, for receiving a request for establishing a real-time wireless BBS from a UE supporting P2P communication mode among a group of UEs, wherein the request includes identification information of other UEs among the group of UEs;
• a determining unit, for determining whether requirements for establishing the real-time wireless BBS among the group of UEs are satisfied or not;
• an allocating unit, for allocating corresponding radio resources to the group of UEs if the requirements for establishing the real-time wireless BBS are satisfied, so that information can be exchanged via direct links between UEs supporting P2P communication mode among the group of UEs.

A UE supporting P2P (Peer-to-Peer) communication mode, comprising:

• a transmitting unit, for sending a request to a network system for establishing a real-time wireless BBS among a group of UEs including the UE, wherein the request includes identification information of other UEs among the group of ULEs;
• a receiving unit, for receiving radio resources allocated according to the request from the network system;
• a communicating unit, for exchanging information with the other UEs via the direct links for P2P communication, by using the radio resources.
