Abstract

The invention discloses a cell reselection parameter optimizing method and device, relates to the technical field of communication, and solves the technical problems that different cells perform reselection according to the same reselection parameter in the prior art. The method includes: respectively determining the maximum adjusting range of cell reselection thresholds under different environments according to the wireless transmission features and different terminal performances under the different environments; determining the cell reselection thresholds under the different environments according to the maximum adjusting range; aiming at the cell reselection threshold under one environment, acquiring the reselection times among cells on cell PS domain services under the environment; adjusting the cell reselection threshold according to the reselection times. The method is mainly applicable to cell reselection.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for optimizing cell reselection parameters. Background technique [0002] The existing planning method for cell reselection is set uniformly across the network based on experience, that is, it is set according to the standard value when the base station is turned on. The most frequently used cell reselection optimization method is the load-based reselection optimization method, that is, when the load of the local cell is too high, the reselection parameters with the neighboring cells are adjusted so that the users at the edge of the cell prefer the neighboring cells, so as to achieve the purpose of load balancing . In addition, there are time-based optimization methods for suppressing ping-pong reselection between systems, methods for suppressing ping-pong reselection based on ping-pong reselection detection, cell reselection methods based on level and...
