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

Embodiment Construction
[0013] The technical means adopted by the present invention to achieve the intended invention purpose are further described below in conjunction with the drawings and preferred embodiments of the present invention.
[0014] figure 1 It is a flowchart of a method for a mobile terminal to search for network priority according to an embodiment of the present invention, such as figure 1 As shown, the method includes:
[0015] Step 1, the mobile terminal reads the stored operator access information and frequency band priority control information, if the stored operator access information and frequency band priority control information are empty, perform step 2, if not empty, perform step 4 ;
[0016] Step 2, the mobile terminal performs a network search according to the default operator access information and frequency band priority control information, initiates a camping process to the cell, and uploads an empty related information identifier to the operator server;
[0017] W...

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...
