Problems solved by technology

Since the working environment of the home micro base station is completely different from that of the traditional macro base station, most of the working hours are in the indoor environment, and the surrounding environment may prevent the GPS device from capturing the number of working satellites, which will affect the synchronization of the micro base station. cause the system to malfunction

Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0014] see figure 1 , figure 2 , a kind of synchronous method of TD-SCDMA home miniature base station, comprises the following steps:

[0015] In the first step, after the TD-SCDMA home base station 1 is powered on, it enters the 3G terminal UE working mode 2, receives the downlink synchronization channel DwPCH of the TD-SCDMA macro base station 3 or other TD-SCDMA home base stations, and obtains the synchronization channel with the TD-SCDMA macro base station 3 or other Downlink synchronization of TD-SCDMA home base stations;

[0016] The second step is to initiate an uplink synchronization request with TD-SCDMA macro base station 1 or other TD-SCDMA home base stations through the uplink synchronization channel UpPCH;

[0017] In the third step, TD-SCDMA macro base station 1 or other TD-SCDMA home base stations feed back synchronization response informat...

Abstract

The invention provides a synchronization method for TD-SCDMA household base stations. The method comprises the following steps that: firstly, a TD-SCDMA household base station is energized and then enters a UE working mode, receives a downlink synchronization channel DwPCH of a TD-SCDMA macro base station, and obtains downlink synchronization with the TD-SCDMA macro base station; secondly, a request for uplink synchronization with the TD-SCDMA macro base station is initiated through an uplink synchronization channel UpPCH; and thirdly, the TD-SCDMA macro base station feeds back synchronization response information through a fast forward access channel FPACH, the TD-SCDMA household base station as a 3G terminal in the UE working mode completes time synchronization, and the TD-SCDMA household base station enters a base-station working mode to complete time synchronization. The method has the characteristics of high precision and good stability.

Description

technical field [0001] The invention belongs to the technical field of TD-SDCDMA base stations, and in particular relates to a synchronization method of a TD-SCDMA home miniature base station. Background technique [0002] Femtocells are an effective supplement to traditional macro base stations. Through the combination of wired and wireless transmission methods, it makes up for the insufficient coverage of traditional macro base stations, and provides home users with efficient communication services including voice, data, video and other services. [0003] At present, CDMA and TD-SDCM all adopt the base station synchronization technology, and the clock of the base station comes from the GPS clock. This method of synchronization requires that the erection of GPS should meet the conditions for its normal operation. WCDMA base stations generally adopt asynchronous technology, and the clock synchronization node RNC of the base station is extracted from the transmission line. ...
