Embodiment Construction

[0041] Preferred embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the application and are used together with the embodiments of the present invention to explain the principles of the present invention.

[0042] first combined with Figure 1 to Figure 3 The method described in the embodiment of the present invention is described in detail.

[0043] Such as figure 1 as shown, figure 1 It is a schematic flow chart of the method described in the embodiment of the present invention, mainly including:

[0044] Step 101: When it is necessary to perform PLMN network search and initiate an initial cell search, the user terminal UE queries the status of each frequency band of the PLMN;

[0045] Step 102: Perform corresponding frequency scan or frequency band set scan according to the predetermined priority of the queried state of each frequency band.

Abstract

The invention discloses a method for accelerating the searching speed of a public land mobile network and a device. The method comprises the following steps that: when a public land mobile network (PLMN) needs to be searched and initial community searching is initiated, user equipment (UE) inquires the states of the PLMN in all frequency bands; according to the pre-set priority of the states of all the inquired frequency bands, corresponding frequency points or frequency band clusters are scanned. According to the invention, in an appropriate community can be found out for resident at the highest speed, so that the power consumption of the UE is reduced, and the user experience is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for searching a network speed of a public land mobile network. Background technique [0002] After the UE (User Terminal) is turned on, it tries to search the PLMN (Public Land Mobile Network), finds a suitable cell to reside in and completes the location registration process, then normal services can be performed. Regardless of the PLMN network search process, after selecting a certain type of PLMN, the UE starts to search for a suitable cell in this PLMN to reside in. This process is called cell selection. [0003] The general process of cell selection is: firstly, it is judged whether there is information about the cells that the PLMN camped on before, and if so, these cells are first tried to camp on; [0004] The process of the initial cell search includes frequency scanning and cell search. Scanning is performed on a given frequency band first, s...
