Patent ID: 8311022

Claim:
A method for accessing a hybrid network including a wireless wide area network and a wireless distributed network, comprising the steps of: regularly transmitting by a base station of the wireless wide area network a synchronization signaling for synchronizing with a downlink common control channel, on a transmission frequency band of the wireless distributed network; transmitting by a wireless terminal a relay request signal requesting to relay a data packet to be transmitted, after receiving the synchronization signaling; sensing by a gateway apparatus the downlink common control channel, and starting to access the wireless distributed network to receive the relay request signal from the wireless terminal at a time instant corresponding to the synchronization signaling; and establishing by the gateway apparatus a connection with the wireless terminal in the wireless distributed network environment, wherein establishing the connection with the wireless terminal comprises transmitting by the gateway apparatus a reply signal to the wireless terminal after receiving the relay request signal, determining by the wireless terminal a gateway apparatus through which a relay operation is to be made by measuring channel conditions, and transmitting a selection signal containing an address of the gateway apparatus through which the relay operation is to be made, and after receiving the selection signal, transmitting a permit signal by the gateway apparatus corresponding to the address included in the selection signal, and further wherein the wireless terminal compares conditions of channels indicated in the reply signal, and selects the gateway apparatus with the best condition of channel and which needs the lowest transmission power for directly communicating therewith as the gateway apparatus through which the relay operation is to be made.
