Abstract
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…
