Problems solved by technology

[0011] The existing methods for judging the GPS timing offset in the TD-SCDMA system cannot detect the GPS timing offset of the base station in time. For example, the existing test and the analysis of the ISCP value of the entire network are not carried out in real time, and the test cannot All stations in the whole network are carried out, so users cannot timely and automatically discover whether there is GPS timing offset in the base stations in the network

Embodiment Construction

[0027] In the embodiment of the present invention, the preset threshold value of the ISCP is set in the base station of the network, and the ISCP value of the network base station is counted, and the base station with the larger ISCP value is piling down, and the ISCP value after the downlink piling is counted, and the comparison is made. The size of the ISCP value before and after downlink piling and the preset threshold value. If the ISCP value before downlink piling is normal, but the ISCP value after downlink piling is greater than the preset threshold, the base station in the network has a GPS timing offset.

[0028] In order to find out the GPS timing offset of a specific base station, the number A of base stations whose ISCP value is greater than the preset ISCP threshold value before downlink piling can be counted first, and then the ISCP value before downlink piling is less than or equal to the preset ISCP threshold value. The number B of base stations whose ISCP value...

Abstract

The invention provides a method for finding GPS timing offset of a TD-SCDMA base station and a device thereof, and belongs to the telecommunication technical field. The method comprises the following steps: setting a threshold of an interference signal code power value of each base station, counting a time slot interference signal code power value of a network side, selecting a base station in which a frequency point with a higher time slot interference signal code power value is located to perform downlink piling on the frequency point, and then recounting the time slot interference signal code power value of the whole network; if the time slot interference signal code power value of a certain frequency point of a certain base station is normal before the piling, while the time slot interference signal code power value is more than the threshold after the piling, then the GPS timing offset of the base station occurs in the network. The method can be widely applicable to a GPS synchronization technology in a TD-SCDMA system.

Description

technical field [0001] The present invention relates to an electrical communication technology, in particular to a method and device for finding GPS timing offset of a TD-SCDMA base station. Background technique [0002] The third generation mobile communication system (TD-SCDMA) is a future terrestrial communication system based on Synchronous Code Division Multiple Access (SCDMA). TD-SCDMA works in TDD (Time Division Duplex) mode, so synchronization between base stations is necessary for TD-SCDMA. Meanwhile, the performance of synchronization between base stations directly affects the performance of the system and the quality of the services it provides. [0003] The synchronization technology in the TD-SCDMA system is mainly composed of two parts, one is the synchronization between the base stations; the other is the uplink synchronization technology between the mobile stations. TD-SCDMA uses GPS (Global Positioning System) or other technologies to achieve synchronizati...
