Problems solved by technology

[0004] like figure 1 shown, assuming that the figure 1 In (a), the UE is dual-standby on the 3G and 4G networks or only on the 4G network; when the UE leaves the 4G network coverage area, it will cause the 4G network to go offline, which may enter the 4G network. figure 1 The situation shown in (b), i.e. when connected to 2G and 3G networks, or when the UE leaves the coverage area of ​​4G and 3G networks, may enter figure 1 In the case shown in (c), it is only connected to the 2G network; and when the UE returns to the 4G network, as figure 1 As shown in (d), the user obviously hopes to return to the 4G network quickly, but due to the consideration of terminal power consumption, it is obviously impossible to make the UE continuously try to search and access the 4G network
[0005] Therefore, how to avoid the waste of UE power caused by blindly searching the network and enable the UE to access a specific network (such as 4G network) as soon as possible has become a technical problem that needs to be solved urgently.

Embodiment 1

[0089] Example 1: Timer

[0090] 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.

[0091] 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.

[0092] Since the terminal stops performing the network search operation based on the position change distance when the number of consecutive fai...

Embodiment 2

[0119] Example 2: Regional update

[0120] Figure 5A It shows a schematic flow chart of performing network search based on the variation of transmission power intensity and / or transmission signal intensity and area update according to an embodiment of the present invention.

[0121] Such as Figure 5A As shown, according to an embodiment of the present invention, the process of performing network search based on the variation of transmission power strength and / or transmission signal strength and area update includes:

[0122] In step 502, the UE disconnects from the LTE network or has not yet registered to the LTE network, and enters the LTE background search working state.

[0123] Step 504, the UE performs an LTE search and registration process based on the variation of the transmit power strength and / or transmit signal strength, see for details figure 2 or image 3 , which will not be repeated here.

[0124] Step 506, counting the consecutive failure times N when the...

[0138] Embodiment 3: Data service requirements

[0139] Image 6 It shows a schematic flow chart of performing a network search based on the variation of transmission power intensity and / or transmission signal intensity and data service requirements according to an embodiment of the present invention.

[0140] Such as Image 6 As shown, according to an embodiment of the present invention, the process of performing network search based on the variation of transmission power intensity and / or transmission signal intensity and data service requirements includes:

[0141]Step 602, the UE disconnects from the LTE network or has not yet registered to the LTE network, and enters the LTE background search working state.

[0142] Step 604, detecting whether the variation of the UE's transmit power strength and / or transmit signal strength in the 2G / 3G network is greater than or equal to the set value, if so, proceed to step 606, otherwise continue to wait. Specifically, for the detect...

Abstract

The invention provides a network search method. The network search method comprises the steps that a terminal stops access to a first network or the terminal has not registered in the first network and stays in a second network; when the change quantity of the transmitting power intensity and / or the transmitting signal intensity of the terminal in the second network is larger than or equal to a preset change quantity, the terminal searches for the first network. The invention further provides a corresponding network search device and the terminal. According to the technical scheme, based on the change condition of the position of the terminal, the network search frequency and / or the number of times of network search of the terminal can be controlled, the situation that waste of power of the terminal is caused by frequent blind network search can be avoided, the terminal can be helped to have access to a specific network as quickly as possible, and user experience can be improved.

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, and the network side changes little, an...
