Abstract

The invention discloses a method for inter-cell synchronization, a base station, a base station controller and a system. The base station controller includes: a receiving unit, configured to receive measurement information of a plurality of cells, and the measurement information includes the uplink signal obtained by the base station measuring the same conventional burst sequence received from the same mobile station in each of the plurality of cells Peaceful timing advance; the determination unit is used to determine a cell set from multiple cells based on the uplink level, and the uplink levels corresponding to the cells in the cell set are the same; the adjustment unit is used to adjust the cell set according to the time advance amount. The air interface clock of at least one cell to synchronize all cells in the cell set. According to the uplink level and timing advance in the measurement information, the air interface clock of the physical cell is adjusted without the need for the mobile station to perform cell handover. In this way, high-precision synchronization between physical cells is achieved, and at the same time, network indicators and user experience are avoided due to frequent cell switching.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, relates to a method for inter-cell synchronization, a base station, a base station controller and a system. Background technique [0002] The multi-site co-cell technology is to logically divide some physical cells of different sites into the same logical cell. For example, 9 cells originally belonging to 3 sites are merged into one cell to provide services to mobile stations through the multi-site shared cell technology. When the mobile station moves within the coverage area of ​​the three sites, there is no need to perform inter-cell handover. The multi-site shared cell technology can reduce the network bandwidth and the number of cell handovers of user equipment, thereby improving service quality and user experience. [0003] In the process of implementing multi-site shared cell technology, in order to combine multiple physical cells of multiple sites into one logical...
