摘要： The present invention provides a wireless communication network system that maintains uplink control for the mobile terminal in peer-to-peer communication. According to one embodiment of the invention, after determining a reliable direct communication link can be set up between the mobile terminals, the network system transmits information including control commands to the mobile terminals for establishing direct communication. The information includes a burst structure type, with the burst structure containing at least one section for carrying control information intended for the network system. After the direct communication is established, the network system continuously listens to signals communicated between the mobile terminals to receive bursts. The network system demodulates received bursts that are communicated between the two mobile terminals to determine whether a received burst contains control information intended for the network system. If control information intended for the network system is included in a received burst, the network performs a corresponding function. In this way, the uplink control for the mobile terminals can be effectively maintained in peer-to-peer communication.
