Embodiment Construction

[0046] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0047] In the prior art, the UE handover judgment rule can only be judged according to the strength of the reference signal. Once the UE is handed over to an over-coverage cell, it will cause it to find no suitable neighbor cell handover, resulting in handover confusion and eventually resulting in service drop. problem with words. Or when the UE ...

Abstract

The present invention provides a method and device for switching and accessing a user terminal, comprising: receiving a measurement report including the timing advance of the adjacent cell reported by the user terminal; analyzing the timing advance of the adjacent cell from the measurement report; calculating the time advance of the adjacent cell The difference between the timing advance of the neighbor cell and the current cell timing advance; compare the difference with the preset threshold value, and when the difference is smaller than the preset threshold value, the user terminal handover to a neighboring cell, and when the difference is not less than the preset threshold value, the user terminal is not handed over to a neighboring cell. The present invention can perform handover and access according to the timing advance of the adjacent cell reported by the user terminal, so that the user terminal can switch to the adjacent cell with a short distance, effectively avoiding the UE from switching to the over-coverage cell, and suppressing the damage caused by the over-coverage cell The island effect can effectively improve the success rate of network switching, reduce the rate of network call drop, and improve the KPI index of the network.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method and device for switching and accessing a user terminal. Background technique [0002] After nearly two years of construction, the Long Term Evolution (LTE) network has begun to take shape, and the network has reached the conditions for commercial use. In order to improve the key performance indicators (Key Performance Indicator, KPI) in the network, various equipment vendors are carrying out engineering optimization, parameter optimization, and algorithm optimization. In the optimization process, switching indicators is the top priority. Since LTE wireless mobile communication is a cellular network, it is necessary to plan the coverage area according to the site of the base station, and then add adjacent cells according to the planned coverage area of ​​each base station. If the actual coverage of a base station far exceeds its planned coverage, it becomes a...
