Problems solved by technology
However, in some application scenarios, the network signal of the environment where the terminal device is located is too poor, and the terminal device fails to send messages to the base station. If the number of failures reaches a certain number of times, it will start a periodic location update timer, such as T3212. At this time, If the location area code (Location Area Code, LAC) does not change, that is, the location area where the terminal device is located does not change, the location update will not be triggered, and it must wait for the time set by the periodic location update timer to expire before proceeding Send a message to the base station to enter the cell
The network coverage corresponding to a location area is usually relatively large, and the time length set by the periodic location update timer is generally relatively long, which will cause the terminal device to be out of service for a long period of time (English: Out of Service) state, and the user may only stay in a place with a poor network signal for a short time. When the user returns to a place with a strong network signal, the terminal device still has no service, which brings great inconvenience to the user.

Embodiment Construction
[0063] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of devices and methods consistent with aspects of the present disclosure as recited in the appended claims.
[0064] In communication systems, such as figure 1 as shown, figure 1 It is a schematic structural diagram of a wireless communication system shown according to an exemplary embodiment. The network coverage area of the communication system is divided into multiple areas, and each area has a location area code (Location Area Code, LAC). Multiple base stations are provided, and the networ...

The present invention provides a position updating method and device. The position updating method comprises the steps of when a terminal device starts a periodic position updating timer, and is in a no-service state, determining the position of the terminal device as the initial position; when a set detection moment reaches, detecting the current position of the terminal device, wherein the duration between the detection moment and the starting moment of the periodic position updating timer is less than the cycle of the periodic position updating timer; when the distance between the current position of the terminal device and the initial position of the terminal device is greater than or equal to a preset threshold value, sending a cell entering request. When the terminal device starts the periodic position updating timer, and is in the no-service state, and if the position change of the terminal device is detected, the cell entering request can be tried again, thereby improving the user experience.
Description
technical field [0001] The present disclosure relates to the technical field of electronic communication, and in particular, to a location update method and device. Background technique [0002] With the development of communication technology, users use more and more terminal devices in their lives, such as smart phones, tablet computers, and smart watches. The terminal equipment enters the cell by sending a message to the base station, so as to obtain communication services. However, in some application scenarios, the network signal of the environment where the terminal device is located is too poor, and the terminal device fails to send messages to the base station. If the number of failures reaches a certain number of times, it will start a periodic location update timer, such as T3212. At this time, If the location area code (Location Area Code, LAC) does not change, that is, the location area where the terminal device is located does not change, the location update wi...
