Method for accessing hybrid network, and gateway apparatus, wireless terminal and communication system thereof

摘要

A method for accessing a hybrid network including a wireless wide area network and a wireless distributed network comprises regularly transmitting by a bare 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; starting by a gateway apparatus to access the wireless distributed network to receive the relay request signal from the wireless terminal st a time instant corresponding to the synchronization signaling sensed on the downlink common control channel; and establishing by the gateway apparatus a connection with the wireless terminal in the distributed network environment.
