A switching method, network device and system

Abstract

Embodiments of the present application provide a handover method, network equipment, and system, which relate to the communication field, and realize fast handover when a terminal equipment needs to perform cell handover, so as to ensure successful cell handover of the terminal equipment and avoid data loss. The specific scheme includes: the source base station obtains the signal quality of the terminal equipment receiving the source base station; the source base station obtains the pre-handover base station group of neighboring cell base stations including G source base stations; Each base station in the base station group sends the user context information of the terminal equipment for control plane handover; when the signal quality is less than or equal to the handover threshold, the source base station performs handover with the target base station. This application is used for cell switching.

Description

technical field [0001] The present application relates to the communication field, and in particular to a handover method, network equipment and system. Background technique [0002] In a wireless mobile communication system, terminal equipment uses wireless signals to access the wireless system through a base station. Due to the mobility of the user, sometimes the serving base station to which the terminal device is currently connected cannot well support the current service. For example, when the terminal device moves near the edge of the cell covered by the current base station, the channel quality between the terminal device and the current serving base station will deteriorate. It may cause the failure of normal communication between the terminal device and the current serving base station. Therefore, in order to ensure the service continuity of the terminal device, it is necessary to switch the terminal device to another base station that can provide better communica...

AI Technical Summary

Problems solved by technology

If a terminal device accesses a service with high mobility QoS requirements, in a high-speed mobile scenario, the existing network handover technology may not be able to complete the handover of the terminal device in time, and cannot well meet the service mobility QoS requirements, resulting in network service failures. Poor, user experience is not high

For example, for the voice service of high-speed mobile terminal equipment, if the existing handover technology is used and the existing handover process is executed, the handover between the terminal equipment and the target base station may not be completed, and the terminal has moved to the coverage of other base stations, resulting in Handover failure or data loss
