Embodiment Construction

[0059] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention , but not all examples. 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.

[0060] In view of the existing technology, after the UE is turned on or disconnected from the network, the time required for the UE to search the network until it can reside stably is too long, the power consumption of the UE increases accordingly, and the user's physical examination is poor. The present invention proposes a new The cell camping selection method is aimed at UE camping on a 4G...

Abstract

The invention provides a cell residence selection method and system. The method comprises the following steps: residing to a first target base station area; determining first target base station resident configuration information based on the first target state activation instruction and the first target frequency point collection instruction; updating the original measurement file to obtain a first measurement file; when residing in a second target base station area, determining second target base station residing configuration information based on a second target state activation instruction and a second target frequency point collection instruction; updating the first measurement file to obtain a second measurement file; and if the residence state is switched, collecting frequency point information in the second measurement file, and selecting a new frequency point for residence based on the frequency point information. According to the invention, the frequency point information of the current cell and the adjacent cell is obtained through periodic measurement of the terminal, the frequency point information is used as prior information, and when the terminal is turned on or off the network, the terminal tries to reside according to the existing frequency point, so that the network searching success rate of the terminal is improved, a large amount of frequency sweeping time is saved, and the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and system for selecting a cell to reside in. Background technique [0002] With the rapid development of wireless communication technology, UE (User Equipment, user terminal) needs to support more and more communication systems, from the initial 2G, 3G and 4G, to the current 2G, 3G, 4G and 5G, in the future there will be more 6G needs to be added, so when the UE is powered on or loses the network, it takes longer and longer to find a suitable cell to reside in and finally to reside in a stable cell through reselection. [0003] Generally, the UE network search and frequency scanning process specifically includes: [0004] 1) Find the frequency point with the strongest signal according to the standard and frequency band supported by the UE first, and try to camp on it. If the camping is successful, the frequency scanning ends; if not, go to step 2...
