Abstract

The invention relates to the field of wireless communication, and discloses a synchronization method and device between base stations. The method includes the steps that when the local base station reaches the search time of synchronization source base stations, whether the synchronization source base station meeting the synchronization condition exists in the adjacent base stations or not is judged; if the synchronization source base station meeting the synchronization condition exists, the synchronization source base station meeting the synchronization condition is switched into the target synchronization source base station of the next base station synchronization; when the local base station reaches the synchronization time, the local base station and the target synchronization source base station are synchronized. Through the synchronization method, synchronization failure caused by changes of a synchronization source self or influences of environmental factors can be effectively prevented, and reliability of base station synchronization is improved.

Description

technical field

[0001] The present invention relates to the field of wireless communication, in particular to a method and device for synchronization between base stations. Background technique

[0002] In the existing base station synchronization technology, there are three main synchronization methods: GPS synchronization technology, 1588 protocol synchronization technology and air interface interception synchronization technology.

[0003] For GPS synchronization technology, because of its high hardware requirements for the base station, it is rarely used in base station synchronization. For the 1588 protocol synchronization technology, because it requires that the communication network where the base station is located must have the function of supporting the 1588 protocol, it is rarely used in the base station synchronization. For the air interface interception synchronization technology, when the base station is started, it searches the timing information of the neigh...
