Problems solved by technology

[0004] For the existing anchor point or relay node assisted base station positioning method, in scenarios where end users are relatively dense, such as pastures, it is necessary to locate each cow / sheep and other terminal nodes. In this case, each Nodes must perform signaling interaction with surrounding anchor points or relay nodes, and at the same time, all anchor points need to perform information interaction with each other, thus occupying a large amount of communication resources. In the case of limited spectrum resources, the above In this case, resource conflicts may occur due to insufficient spectrum resources caused by too many interactive signaling, thus failing to achieve the purpose of positioning. Therefore, the first problem to be solved by the present invention is how to further reduce the positioning process while ensuring positioning accuracy. Signaling interaction in , thus reducing the probability of resource conflicts

Embodiment 1

[0026] Embodiment one: if image 3 As shown, an optimization method for terminal positioning includes the following steps:

[0027] Step S1: The terminal to be positioned automatically triggers positioning, and broadcasts location detection information to multiple anchor points around, wherein, the terminal to be positioned first listens to the channel before sending the location detection information to the surrounding anchor points, if the listening channel is idle, then Send it immediately, if the listening channel is busy, then send it after a random rollback period of time t;

[0028] Specifically, the periodic trigger positioning detects the mobile state of the node through the sensor, and different mobile states trigger different periods, including the following steps:

[0029] Step S101: the node triggers an initial positioning when it first accesses the network;

[0030] Step S102: Preset two moving frequency first value Th1 and second value Th2, where Th1>Th2, if t...

Embodiment 2

[0041] Embodiment 2: an optimization method for terminal positioning, comprising the following steps:

[0042] Step S1: The terminal to be positioned triggers positioning according to the moving distance of the terminal to be positioned. Specifically, the moving distance trigger of the terminal to be positioned first sets a limit value S of the moving distance, and each time the terminal to be positioned detects that the moving distance reaches When the limit value S or an integer multiple of the limit value S will trigger positioning, and broadcast position detection information to multiple anchor points around, where the terminal to be positioned first listens to the channel before broadcasting the position detection information to each anchor point, if If the listening channel is idle, it will be sent immediately; if the listening channel is busy, it will be sent after a random backoff time t;

[0043] Step S2: After the anchor point 1 receives the position detection inform...

Embodiment 3

[0047] Embodiment three: an optimization method for terminal positioning, comprising the following steps:

[0048] Step S1: The terminal to be positioned triggers positioning according to the number of steps the terminal to be positioned moves. The number of moving steps of the terminal to be positioned triggers the setting of a limit value L of the number of moving steps. Each time the terminal to be positioned detects that the number of moving steps reaches When the limit value L or an integral multiple of the limit value L will trigger positioning, and broadcast position detection information to multiple anchor points around, where the terminal to be positioned first listens to the channel before broadcasting the position detection information to each anchor point, if If the listening channel is idle, it will be sent immediately; if the listening channel is busy, it will be sent after a random backoff time t;

[0049] Step S2: After each anchor point receives the position d...

Abstract

The present invention proposes an optimization method for terminal positioning, using a periodic positioning method or triggering positioning according to the moving distance or moving steps of the terminal to be positioned, further reducing the number of positioning times, thereby reducing the power consumption of the terminal or the terminal to be positioned; In the process of signaling interaction between the anchor point and the terminal to be positioned, the anchor point is equipped with an identity identification ID, and it is judged whether there is a central anchor point participating in the ranging process to further reduce the signaling interaction between the anchor points. Reduce the probability of resource conflicts and ensure communication performance.

Description

technical field [0001] The invention relates to the technical field of communication positioning, in particular to an optimization method for terminal positioning. Background technique [0002] Terminal or node positioning refers to the technology or service that obtains the position information (latitude and longitude coordinates) of end users or nodes through specific positioning technology, and marks the position of the positioned object on the electronic map. Existing commonly used positioning methods mainly include the GPS method and base station positioning. Among them, the positioning method based on GPS uses the GPS positioning module on the terminal user to send its own position signal to the positioning background to realize terminal positioning. Base station positioning is to use the base station to calculate the distance of the terminal user's distance to determine the terminal position, such as figure 1 As shown, each terminal or node needs to perform multiple...
