A method and device for suppressing ping-pong switching

Abstract

The embodiment of the invention provides a method and a device for inhibiting ping-pong handover. The method comprises the following steps: if it is judged that the time of ping-pong handover of the mobile terminal within the coverage range of the first cell in the first preset time period is greater than the first preset threshold value, obtaining the network signal strength of the second cell with which the ping-pong handover occurs; Obtaining the frequency specific deviation of the neighboring area, the personality deviation of the neighboring area, the preset hysteresis parameter and the preset threshold parameter corresponding to the first cell; If it is judged that the network signal strength + frequency-specific deviation of neighboring area + personality deviation of neighboring area is greater than the preset threshold parameter, ping-pong handover suppression processing is performed on the mobile terminal. The method and the device provided by the invention improve the efficiency of inhibiting ping-pong handover.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular to a method and device for suppressing ping-pong switching. Background technique [0002] With the rapid development of communication technology, people have higher and higher requirements for the quality of voice calls. Therefore, ping-pong switching, as one of the main factors affecting the quality of voice calls, has attracted more and more attention. [0003] Under the existing technical conditions, the current methods for suppressing ping-pong handover mainly include handover parameter optimization, cell layering, ping-pong handover suppression, and coverage optimization. Specifically, the commonly used methods include: (1) changing the CIO of room distribution to surrounding macro stations to -10; (2) increasing the handover trigger threshold by 3 to 5 dB to suppress the number of handover triggers; (3) changing the high-level room distribu...

Problems solved by technology

[0004] Wherein, the pertinence of method (1), (2) and (4) is relatively poor, because can't distinguish ping-pong handover user and common user, often influence its normal handover while suppressing the ping-pong handover of high-level indoor subdistrict; and method ( 4) It has high requirements on the surrounding environment, such as: whether the site location is too close to be adjusted, whether the site coverage direction, whether the downtilt angle is adjustable, whether the site power is limited, etc.; method (3) for indoor distribution systems, separate Configuring the cell requires RRU, combiner, optical fiber and other equipment, which is costly and poor in promotion; method (5) has low accuracy in user identification for ping-pong switching, resulting in poor optimization effect

In summary, the existing methods greatly affect the efficiency of ping-pong handoff suppression
