Ping-pong switching suppression method and device

Abstract

The embodiment of the invention provides a ping-pong handover suppression method and device. The method comprises the steps that a source cell receives a measurement report reported by a user terminal; determining longitude and latitude information corresponding to the user terminal according to the measurement report; judging whether the user terminal is located in a ping-pong suppression area ofthe source cell or not according to the longitude and latitude information corresponding to the user terminal; if the user terminal is located in the ping-pong suppression area of the source cell, ignoring the measurement report; if the user terminal is located outside the ping-pong suppression area of the source cell, sending a switching instruction to the user terminal according to the measurement report. The measurement error of longitude and latitude information is far less than the error depending on wireless signal measurement parameters, so that the accuracy of inhibiting ping-pong switching can be improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for suppressing ping-pong switching and a device for suppressing ping-pong switching. Background technique [0002] With the popularity of mobile Internet technology and mobile terminals, users can use mobile terminals to perform various services, such as surfing the Internet, video on demand, sending and receiving emails, downloading, etc.; With the gradual increase of users, the user's demand for network bandwidth and capacity is also increasing. Therefore, the TD-LTE (Time Division-Synchronous Code Division Multiple Access LongTerm Evolution) network system adopts a hierarchical networking method, such as D-band same-frequency group network, F+D frequency band networking, etc., to meet the increasing number of users and various business needs. [0003] Among them, because the wireless signal is greatly affected by the environment, at a certain position in the w...

Problems solved by technology

[0003] Among them, because the wireless signal is greatly affected by the environment, at a certain position in the wireless signal coverage area, the signal strength of the two cells may change drastically, and then the user terminal at this position will switch back and forth between the two cells; thereby reducing communication quality of the user terminal

Among them, in the prior art, the ping-pong handover is suppressed according to the signal strength offset of the cell, that is, it is judged whether the signal strength offset of the cell satisfies the offset threshold, and if so, the user terminal is allowed to perform handover; Instability, resulting in inaccurate offset measurements, making the suppression of ping-pong switching less accurate
