Embodiment Construction

[0072] Generally speaking, according to the traditional cell handover mechanism, the terminal device will perform cell measurement according to the control information issued by the base station during the moving process. When the measurement results meet the conditions of the handover event indicated by the base station (for example, A3 event, A5 event, B1 event, B2 event, etc.), the terminal device will report a measurement report to the base station to trigger the base station to control the terminal device to complete the cell switch. Therefore, based on the traditional cell handover mechanism, the terminal equipment can only determine the timing to trigger the handover based on the monitored signal quality, but cannot judge when the handover success rate is higher. Especially in high-speed mobile communication systems, terminal equipment often needs to perform cell switching at a high frequency, and the switching time is limited. If the timing of switching with a high suc...

Abstract

The present application provides an intelligent switching method and device, which relate to the technical field of communication and can reduce the reconstruction rate and call drop rate. The method includes: the terminal device acquires map information from the intelligent server, the map information is used to indicate the recommended handover area, and the handover success rate of the recommended handover area is greater than a preset threshold value; when the terminal device detects that the cell signal meets the preset handover condition , and the terminal device is located in the recommended handover area, the terminal device reports the first measurement report, the first measurement report is used for the terminal device to perform cell handover, and the cell signal includes the signal of the serving cell of the terminal device and the signal of the neighboring cell of the serving cell; the terminal The device performs cell handover based on the first measurement report.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 201910341493.8 and the invention title "A Smart Switching Method and Device" filed with the China Patent Office on April 26, 2019, the entire contents of which are incorporated in this application by reference. technical field [0002] The present application relates to the field of communication technologies, and in particular to an intelligent switching method and device. Background technique [0003] In a high-speed mobile communication system, such as a high-speed rail mobile communication system, terminal equipment (terminal equipment) moves at high speed along with the high-speed rail, so the terminal equipment needs to perform cell switching at high frequency. Because the moving speed is too fast, the switching time is shortened, which leads to problems such as the reconstruction rate and the call drop rate increase. Contents of the invention [0004] The presen...
