Abstract

The invention provides a 2G neighboring cell set adaptation method based on scenarized eSRVCC service. The method comprises the following steps: collecting configuration data and performance indicatordata of an eSRVCC existing network within a preset range; obtaining a 4G cell information table and a 4G and 2G station distance table from the configuration data; determining a plurality of neighboring cell scenes of a 4G macro station cell according to the 4G cell information table and the 4G and 2G station distance table by adopting a neighboring cell configuration rule; for each neighboring cell scene, obtaining a neighboring cell set corresponding to the neighboring cell scene according to a neighboring cell selection strategy in the neighboring cell scene, as well as the 4G cell information table and the 4G and 2G station distance table; and adjusting the neighboring cell set, and obtaining a 2G neighboring cell set table to be added to each 4G macro station cell. By adoption of themethod provided by the invention, fast and effective check can be made on the cells in the whole network.

Description

technical field [0001] The invention relates to a wireless network optimization technology, in particular to a 2G neighbor cell set matching method based on a scene-based eSRVCC service. Background technique [0002] Due to the difference in frequency band characteristics, there is a certain gap between LTE network and GSM network in terms of coverage depth and breadth. Therefore, it is inevitable for VOLTE users to switch from LTE network to GSM network through ESRVCC. [0003] For ESRVCC handover, if the addition of the GSM neighbor cell of the LTE base station is incomplete, the user will drop the call, and the cell reselection process will be initiated repeatedly, resulting in the problem that the handover cannot be carried out smoothly and the user experience is poor. [0004] To ensure the success rate of handover, it is necessary to configure a reasonable 2G neighboring cell for a single 4G eSRVCC cell. At present, the main implementation method of checking neighbori...
