Method and system for predicting best adjacent region of mobile terminal

Abstract

The invention discloses a method and a system for predicting a best adjacent region of a mobile terminal. The method comprises the following steps: acquiring the current moving speed of a mobile terminal and judging whether the current moving speed is greater than a preset first speed threshold; if the current moving speed is greater than the preset first speed threshold, acquiring base stations of which the distances from the mobile terminal are smaller than a preset spacing threshold, and acquiring the included angle between the connecting line of the mobile terminal and each base station and the line of moving direction of the mobile terminal and the signal strength of each base station; acquiring the base station meeting the condition that the signal strength is greater than a first signal strength threshold and the condition that the included angle between the connecting line of the mobile terminal and the base station and the line of moving direction of the mobile terminal is minimum among multiple included angles, and reporting a connection request of the mobile terminal to the base station. By using the method and the system, next best adjacent region can be predicted during high-speed movement and reported to a corresponding base station, the base station can provide service for a longer time after switching, and thus, ping-pong switching and disorderly invalid switching are reduced.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and system for realizing the best neighbor cell prediction of a mobile terminal. Background technique [0002] The popularity of high-speed railways has greatly facilitated people's travel. However, as the speed of high-speed trains continues to increase, people find that the quality of mobile phone calls in high-speed trains is also declining, especially when the speed exceeds 200 km / h, there are often network drops, dropped calls, calls that cannot be made, intermittent calls, and call noise , slow Internet speed and other issues. One of the main reasons is the frequent switching, ping-pong switching and invalid switching of the serving cell caused by the high-speed movement of the mobile phone. These problems can be improved by optimizing the network coverage, such as building a high-speed rail private network, and at the same time need to opt...
