Seamless synchronization source switching method and system

Abstract

The invention discloses a seamless synchronization source switching method and a system. The method comprises steps that integrated small base stations are utilized for scanning to acquire the base station information which can be used as synchronization sources; one synchronization source with strongest signals is selected as a current synchronization source to carry out real-time synchronization, and other synchronization sources are taken as candidate synchronization sources; polling detection on the candidate synchronization sources is carried out to acquire a target candidate synchronization source; when the current synchronization source is detected to be in a state of signal deterioration, switching to the target candidate synchronization source is carried out. Through the method, when the base station is about to generate loss of synchronism, rapid seamless switching to the candidate synchronization source which has best signals and be in a normal synchronization state can be realized, and sequence and frequency adjustment is not required, and thereby stability of the base station and an excellent user experience environment are guaranteed.

Description

technical field [0001] The present invention relates to the technical field of base station communication, in particular to a method and system for seamlessly switching a synchronization source. Background technique [0002] With the continuous advancement of technology and networks, as well as the popularization of mobile devices, users have higher and higher requirements for network quality and transmission rate. Traditional 2G / 3G and WIFI can no longer meet the needs of users. LTE adopts advanced transmission protocols, which greatly improves the quality and speed of the network, and has become the mainstream standard for construction by major operators. LTE smallcell is a small base station, which can well solve important problems such as insufficient indoor deep coverage and difficult capacity expansion in hotspot areas during TD-LTE network construction. Its small size is convenient for installation and portability, and the family-level smallcell can also be installed...

Problems solved by technology

Therefore, it is necessary to judge whether the candidate synchronization source is in a state available for synchronization. The conventional judgment needs to be rescanned, and rescanning will interrupt the user's business

At the same time, during the re-synchronization process, the base station needs to re-adjust its own timing and frequency, which also affects user services during the adjustment process, causing users to drop offline and experience poor experience.
