Embodiment 1

[0157] Example 1: Timer

[0158] In the above technical solution, preferably, when the number of consecutive failures of the terminal's search operation on the first network is greater than or equal to the preset number of times, further comprising: starting a timer, and the terminal After timeout, initiate a search operation for the first network; wherein, if the terminal fails to initiate a search operation for the first network after the timer expires, restart the timer.

[0159] In this technical solution, a timer-based network search method is adopted, that is, every time the timer expires, the terminal performs a search operation on the first network, and if successful, accesses the first network; otherwise, resets the timer to After waiting for the timer to expire again, re-execute the search operation for the first network.

[0160] Since the terminal stops performing the network search operation based on the change of the cell (serving cell and / or neighboring cell) w...

Embodiment 2

[0187] Example 2: Regional update

[0188] Figure 8A It shows a schematic flow chart of performing network search based on cell change / location change distance and area update according to an embodiment of the present invention.

[0189] Such as Figure 8A As shown, the process of performing network search based on cell change / location change distance and area update according to an embodiment of the present invention includes:

[0190] Step 802, the UE disconnects from the LTE network or has not yet registered to the LTE network, and enters the LTE background search working state.

[0191] In step 804, the UE may perform an LTE search registration process based on a cell change. For details, refer to image 3 or Figure 4 ; Alternatively, the UE may perform an LTE search registration process based on a location change distance, for details, see Figure 5 or Figure 6 , which will not be repeated here.

[0192] Step 806, counting the consecutive failure times N when the ...

Abstract

Provided is a network searching method, comprising: a terminal getting out of service from a first network or having not yet registered to the first network (202); and when it is detected that there is a need for data service, the terminal performing a searching operation on the first network. The present invention also proposes a corresponding network searching device and a terminal (204). By means of the technical solution of the present invention, not only the frequency and / or the number of times of network searching of a terminal can be controlled to avoid a waste of power consumption of the terminal caused by frequently blind network searching, but also the terminal can be facilitated to access a specific network as soon as possible thus to improve user experience.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular, to a network search method, a network search device and a terminal. Background technique [0002] The communication field has entered the 4G era, and the entire network architecture has undergone great changes compared with 2G / 3G. As the most basic and important requirement for wireless communication, how to implement voice services in 4G will bring new challenges to network operators and terminal manufacturers. At this stage, major chip manufacturers and 3GPP organizations have proposed different solutions for operators to choose, mainly including single card dual standby solution (SGLTE / SVLTE), circuit domain fallback solution (CSFB), SRVCC / VOLTE, among them, the SVLTE (Simultaneous Voice and LTE, LTE and voice network synchronous support) single-card dual-standby solution has no special requirements for the network, requires little changes on the network ...
