Embodiment Construction

[0025] In order to reduce the facility cost for synchronizing the base stations of the microcellular network, an embodiment of the present invention provides a method for synchronizing the base stations of the microcellular network. Synchronization of base stations.

[0026] Referring to FIG. 1 , it is a network diagram of a system to which the method of the present invention is applied. The system includes a macro base station, a micro base station, a gateway (GW) and a user terminal (UE).

[0027] Among them, the information channels 1, 2, 4, and 5 between the macro base station and GW, the micro base station and GW, the micro base station and UE, and the macro base station and UE are existing in the prior art. The information channel 3 between the base stations enables the macro base station and the micro base station to communicate with each other. Since the micro base station is geographically located within the coverage of the macro base station, the two base stations c...

Abstract

The method comprises: the macro base station broadcast network side creates an absolute time; the micro base station gets the transmission time delay between itself and the macro base station, and uses the transmission time delay and the absolute time of said network side to adjust its local working time to complete the time synchronization. The invention also reveals a system thereof, a micro base station and a macro base station.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method, a system and a base station for synchronizing base stations of a microcellular network. Background technique [0002] With the continuous growth of data services, the future network configuration will increasingly include a layered coverage network with a hybrid network of macro cells and micro cells. The macro cell achieves wide coverage and provides lower-speed service connections; the micro cell achieves micro-cell coverage and provides high-speed, high-capacity service connections. The systems and frequency bands used by the two can be the same or different. For example, macro cells can adopt 2G systems such as Global Mobile Communications (GSM) and Code Division Multiple Access (CDMA), or 3G systems such as Wideband Code Division Multiple Access (WCDMA), and micro cells can use wireless local area networks (WiFi) , Digital European Cordless Telephone (DECT),...
