Problems solved by technology

[0004] However, due to the different causes of low-speed users, if all low-speed users are moved out blindly, it may cause low-speed users formed due to the characteristics of train operation to become high-speed users again when the train speeds up again, resulting in call drop and normal communication.

Embodiment approach

[0037] Based on the above, an implementation manner of step 102 in this embodiment includes:

[0038] Step 1021, the RNC judges whether the speed state of the user terminal is a low speed state or a stable medium speed state; if the judgment result is yes, execute step 1022; otherwise, execute step 1023.

[0039] Wherein, in order to facilitate judging the moving state of the user terminal, the RNC presets a measurement monitoring cycle, so as to judge the moving state of the user terminal according to the speed state of the user terminal within the measurement monitoring cycle. Wherein, the length of the measurement and monitoring period can be flexibly set according to actual needs. For example, if a higher-precision determination result is required, the measurement and monitoring period can be set to be longer; otherwise, the measurement and monitoring period can be set to be shorter.

[0040] If the speed state of the user terminal is always in the low-speed state or stabl...

Abstract

The invention provides a method and a device for migrating users in a high-speed railway communication network, which comprises the following steps: obtaining the speed state of a user terminal according to a plurality of speed values and at least one preset speed threshold value reported by the base station within the speed deciding period; obtaining the movement state of the user terminal according to the speed state of the user terminal; sending measurement control information to the user terminal according to the movement state and characteristic information of a high-speed railway communication network in which the user terminal is positioned; causing the user terminal to carry out 1G / 2A event measurement and / or the period measurement of the neighbor cell to the appointed neighbor communication cell, and reporting a measurement report; and migrating the user terminal to a target communication cell according to the measuring results reported by the user terminal. According to the technical scheme disclosed by the invention, low-speed users can be migrated out of the high-speed railway communication network so as to improve the communication quality of high-speed users under the condition of ensuring the normal communication of the users.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a method and device for user migration in a high-speed rail communication network. Background technique [0002] In order to adapt to the operating environment of high-speed rail (hereinafter referred to as high-speed rail) and ensure the communication quality of high-speed rail users, the signal strength in the high-speed rail communication network is relatively high, usually stronger than that of the public communication network (hereinafter referred to as the public network). Based on this, some public network users (usually pedestrians or vehicle users on buses) close to the high-speed rail communication network will be absorbed into the high-speed rail communication network, and public network users are usually low-speed users. In addition, low-speed users will also be formed due to the characteristics of train operation (such as entering, exiting, emergency braking, etc....
