摘要： The present invention provides a wireless network system for establishing peer-to-peer communication between mobile terminals. Upon determining that peer-to-peer communication can be established between two mobile terminal, the wireless network system transmits to each of the mobile terminals information about radio resources used by the other one of the mobile terminals. Each mobile terminal then uses the radio resources information to test the characteristics of a dedicated uplink channel between the other one of the mobile terminals and the network system. Thus, no separate radio channel needs to be allocated for the channel testing. Furthermore, each mobile terminal uses the same radio resources to establish a dedicated radio channel in the peer-to-peer communication with the other one of the mobile terminals, which were previously used by itself for communication with the network system on the dedicated uplink channel. In this way, the network system does not need to allocate additional radio resources for establishing the peer-to-peer communication, thus simplifying the radio resources re-allocation scheme, while ensuring that the quality of the channels is the same as tested.

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.
