Processing method, base station and system for group switch

Abstract

The invention discloses a processing method and a device for group switch. The method comprises the following steps: before switching, grouping users in a cell; setting different switching conditions for the users in different groups; and according to the set switching conditions, and switching the users in the different groups in different periods. In the invention, the problems of large group switching amount and frequent group switching of rapid transit railway communication in the prior art can be saved, the purposes of reducing group switch pressure and the possibility of simultaneously switching are realized, and the communication quality and the stability of the system are improved.

Description

technical field [0001] The present invention relates to wireless technology in the communication field, in particular to a group handover processing method, base station and system. Background technique [0002] The existing high-speed railway passenger communications mainly have two business characteristics: [0003] (1) The number of users is large and the business volume is large. During the journey, passengers have high demand for communication services, and the service duration is long. [0004] (2) High-speed movement and frequent switching. In the direct coverage of the Public Land Mobile Network (PLMN for short) or repeater coverage, in order to obtain a large user capacity, the radius of the cell cannot be too large. Assuming that there is a base station every 3.5km (for example, the actual layout of the Beijing-Tianjin high-speed railway), the one-way train will perform a handover every 100s or so. [0005] Due to the business characteristics of the above-menti...

Problems solved by technology

[0009] The first purpose of the present invention is to propose a group handover processing method to reduce the pressure of group handover and the probability of simultaneous handover in order to solve the problem of large and frequent group handover in high-speed railway communication in the prior art

[0010] The second purpose of the present invention is to propose a base station to solve the problems in the prior art that the number of group handovers in high-speed railway communications is large, frequent signaling loads are brought to the base station, and the terminal is prone to call drop or network disconnection, so as to reduce the number of base stations The pressure of group switching and the probability of simultaneous switching of user terminals

[0011] The third purpose of the present invention is to propose a group handover processing system to reduce the pressure of group handover and the probability of simultaneous handover in order to solve the problem of large and frequent group handover in high-speed railway communication in the prior art
