A location-based cell handover method, terminal and base station

Abstract

The present invention provides a location-based cell handover method, a terminal and a base station. The method includes: receiving the real-time location information of the terminal sent by a positioning device every first preset time period; judging whether the real-time location information of the terminal is Satisfy the first preset condition. If it is determined that the first preset condition is met and the timer is not started, then send the real-time location information of the terminal to the base station for the base station to judge whether the real-time location information of the terminal meets the second preset condition , if so, the base station triggers the handover of the terminal from the source cell to the target cell. In this method, the base station and the terminal obtain accurate terminal location information, utilize the characteristics of the signal strength of the track wireless coverage and the relatively stable location, and trigger the handover by means of the terminal reporting the location and network decision-making, which can avoid the terminal's high-speed running. The problem of inaccurate signal measurement improves the handover success rate of the terminal from the source cell to the target cell.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a cell switching method based on location, a terminal and a base station. Background technique [0002] With the acceleration of China's industrialization and urbanization, economic activities have developed rapidly, and rail transit has also been vigorously developed as an infrastructure. The construction and operation mileage of high-speed rail, railway, light rail, and subway has increased rapidly. By the end of 2017, my country's railway operating mileage reached 127,000 kilometers, including 25,000 kilometers of high-speed railways. A total of 34 cities in mainland China have completed and put into operation 5,021.7 kilometers of urban rail lines . During the safe operation of rail transit, a safe mobile communication system is needed to support the control and management of running trains. [0003] In the mobile communication system, in order to solve the pr...

Problems solved by technology

The disadvantage of this criterion is that if the signal strength of the original base station still meets the requirements, it will cause too many unnecessary cell handovers

[0006] In the current mainstream technical solutions, the implementation of system handover is complicated, the success rate of handover is low, and it cannot be applied to the new environment of high-speed operation of the terminal. , did not make full use of the characteristics of linear wireless coverage such as rail transit and high-speed railways to design handovers, did not take advantage of the development trend of vertical integration of various layers of the existing information system, and only considered the information of the wireless system to solve the handover problem when designing handovers problems, it is difficult to realize the potential capacity of the system

(2) When the terminal is moving at high speed, there will be problems with inaccurate measurement of signal strength and quality. Handover based on signal strength and quality will lead to a decrease in the success rate of handover
