A method for mobile terminal to search network priority

Abstract

The invention discloses a network priority search method for a mobile terminal. The method includes the steps that step1, the mobile terminal reads stored operator access information and frequency band priority control information, if the information is empty, step 2 is executed, and if the information is not empty, step 4 is executed; step 2, the mobile terminal conducts network search according to the default information, initiates a cell residence process and uploads related information identification with empty content; step 3, the mobile terminal receives updated information issued by an operator server and finishes the cell residence process; step 4, the mobile terminal conducts network search according to the stored information, initiates the cell residence process and uploads the related information identification, and the operator server judges whether information needs to be updated or not; if yes, the mobile terminal receives the updated information issued by the operator server and finishes the cell residence process; if not, the mobile terminal receives the empty information issued by the operator server and finishes the cell residence process.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a method for a mobile terminal to search for network priority. Background technique [0002] The Long Term Evolution (LTE) project is an evolution of 3G and a transition between 3G and 4G technologies. It improves and enhances the 3G air interface. It adopts advanced technologies such as OFDM and MIMO to increase the peak value of user upload and download. rate, effectively improving the performance of cell edge users, increasing cell capacity and reducing system delay. [0003] At present, the advantages of LTE technology have attracted widespread attention from major operators at home and abroad, and they have invested heavily in the development of LTE networks, and the LTE industry has developed rapidly. Global LTE network operations are technically divided into three operating modes: LTE FDD single network, TD-LTE single network, TD-LTE and LTE FDD dual-m...

AI Technical Summary

Problems solved by technology

This information only includes access technology information, not the frequency band information corresponding to the access technology, and the information in the card cannot even distinguish the priority order of LTE FDD and TD-LTE

The remaining priority processing will be implemented by the mobile terminal itself, and it is a fixed configuration, which cannot be adaptively changed according to the operator to which the user card belongs
