Abstract

A system and method for peer-to-peer communications in cellular communications systems are provided. A method for communications device operations includes receiving a peer list at a communications device, where the peer list includes a list of reachable communications devices and device-to-device (D2D) capability information of the reachable communications devices, selecting a peer from the peer list, sending a content request comprising an indication of a content to a communications controller serving the communications device, and receiving the content from the peer over a channel established by the communications controller.

Description

[0001] This application claims U.S. Serial No. 13 / 105,234, filed May 11, 2011, entitled "System and Method for Peer to Peer Communications in Cellular Communications Systems" The content of this earlier application is incorporated by reference into this application. technical field [0002] The present invention mainly relates to digital communication, specifically, to a peer-to-peer (P2P) communication system and method in a cellular communication system. Background technique [0003] Due to the popularity of P2P applications, such as file sharing and multimedia conferencing, P2P traffic increases rapidly. Usually, at a logical level, P2P communication occurs between a first peer and a second peer as point-to-point (PTP) communication (a so-called point-to-multipoint, PTP communication). A similar form of communication of PTM) occurs between a first peer and multiple second peers). P2P communication does not need to pass through or be controlled by communication controlle...
