District switching judging method and equipment

Abstract

The invention discloses a district switching judging method and equipment. The method comprises the steps as follows: a source base station receives a measurement result reported from a mobile station and acquires the movement speed of the mobile station; the source base station determines a corresponding district switching judging threshold according to the movement speed of the mobile station; and the source base station carries out the district switching judgment according to the measurement result reported from the mobile station and the determined district switching judging threshold corresponding to the movement speed of the mobile station. According to the invention, the time for starting a switching process can be adjusted flexibly according to the movement speed of the mobile station, and the time for switching the mobile stations with different speeds can be determined more reasonably.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for cell handover decision. Background technique [0002] In the LTE (Long Term Evolution, Long Term Evolution) mobile communication network, the movement of UE (User Equipment, user equipment) or changes in the surrounding environment may cause signal fading, which is the main reason for starting UE to switch between base stations. The start of the handover process by the base station depends on the UE's measurement report, and the base station can initiate a handover to a neighboring base station with the best signal according to the content of the measurement report. [0003] Such as figure 1 As shown in FIG. 2 , it is a schematic flow diagram of UE handover between base stations in the existing LTE system. Among them, the following steps are mainly included: [0004] The source base station sends the measurement configuration to the UE. A...

Problems solved by technology

[0007] In high-speed mobile scenarios such as high-speed railway applications, the mobile speed of the UE is usually higher than 350km / h. During the handover process, after the UE reports the measurement results, it is possible to make a handover decision at the source base station, send a handover request to the target base station, and wait At the same time as a series of signaling interactions such as the handover confirmation of the target base station, the UE has already moved to the coverage area of ​​the target base station. At this time, the overall process of the handover has not been completed, and the UE is still receiving the service of the source base station. Has dropped a lot, it is likely to affect the actual transmission performance and service quality
