METHOD FOR ACCESSING HYBRID NETWORK, AND GATEWAY APPARATUS, WIRELESS TERMINAL AND COMMUNICATION SYSTEM THEREOF
First Claim
1. 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;
starting by a gateway apparatus 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 sensed on the downlink common control channel; and
establishing by the gateway apparatus a connection with the wireless terminal in the distributed network environment.

Abstract
A method for accessing a hybrid network including a wide area network and a distributed network, a gateway apparatus, a wireless terminal and a gateway communication system are disclosed for reducing the power consumption of the wireless terminal which is an access gateway. The method comprises: sensing by a gateway apparatus a relay request slot on a downlink common control channel of the wide area network; transmitting by a wireless terminal a relay request signal requesting to relay a data packet to be transmitted, in the relay request slot on the downlink common control channel; and if the relay request signal from the wireless terminal is sensed in the relay request slot, establishing by the gateway apparatus a connection with the wireless terminal in a distributed network environment. As such, the gateway apparatus accesses the wireless distributed network only when the surrounding wireless terminals require data relay, without sensing signals on both networks simultaneously, in order to reduce the power consumption.
