[0042] figure 2 A schematic structural diagram of a hybrid network composed of a wide area cellular network and a wireless distributed network involved in the present invention is shown. figure 2 The middle BS represents the base station in the wide-area cellular network, and its coverage area is a large ellipse. The base station communicates with the terminal Ubi or GW within the coverage area on the f2 frequency band. The smaller ellipse represents the coverage of the wireless distributed network, which can be a variety of networks such as wireless local area network (WLAN), ad hoc network (Ad hoc), and Bluetooth (Bluetooth). This kind of network works in the f1 frequency band (f1 is not equal to f2), so there is no interference between the wireless distributed network and the wide area cellular network. GW means a gateway node, which is a dual-mode wireless terminal capable of supporting simultaneous communication in two networks, and can successfully connect to any netw...

[0092] Figure 14 is a schematic diagram of the timing relationship of channels involved in the second embodiment of the present invention. In the second embodiment, the base station BS of the wide area network periodically sends synchronization signaling synchronized with the downlink common control channel on the transmission frequency band of the wireless distributed network. The wireless terminal Ubi sends relay request information after receiving the synchronization signaling, and the gateway device GW can start accessing the distributed network corresponding to the synchronization signaling to receive the relay request information from the wireless terminal Ubi. For example, the gateway device starts accessing the distributed network at a time corresponding to the synchronization signaling by monitoring the downlink common control channel of the wide area network.

Abstract

The invention discloses a method for accessing a hybrid network comprising a wide-area network and a distributed network and gateway equipment, a wireless terminal and a gateway communication system thereof, aiming at reducing the consumption of the wireless terminal accessing a gateway. The method comprises the following steps: the gateway equipment monitors a relay request timeslot on a downlink public control channel of the wide-area network; the wireless terminal sends a relay request message which requests to conduct relay on the data grouping to be sent in the relay request timeslot on the downlink public control channel; and if the gateway equipment monitors the relay request message from the wireless terminal in the relay request timeslot, a connection with the wireless terminal is established under an environment of the distributed network. Therefore, the gateway equipment only accesses the wireless distributed network when the peripheral wireless terminals have data relay demand without monitoring the signals on two networks simultaneously, thus reducing power consumption.

Description

[0001] This application is a divisional application of the invention patent application 200510109212.4 filed on October 19, 2005, entitled "Method for accessing hybrid network, gateway device, wireless terminal and communication system". technical field [0002] The present invention relates to the access of a hybrid network, in particular, to a method for saving power consumption and accessing multiple networks of a hybrid network, a gateway device, a wireless terminal and a communication system, while ensuring that messages from the hybrid network can be received at the same time Under the premise of different network signals, the time for the gateway node to listen to two networks at the same time in the idle state is reduced, thereby reducing the power consumption of the gateway node per unit time and prolonging the standby or service time of the gateway node. Background technique [0003] With the popularization of wireless portable terminals and the deepening of communi...
