Embodiment Construction

[0046] The user equipment positioning method in this embodiment can be applied to a 5G communication network, and the local topology of the 5G communication network is as follows figure 1 As shown, it includes a GMLC network element, an AMF network element, a first LMF network element, and at least one base station, and the first LMF network element is connected to these base stations to form a binding relationship. Specifically, the first LMF network element and the base station can be Set the management association relationship between the first LMF network element and the base station in the management system, that is, form the binding relationship between the first LMF network element and the base station. In this embodiment, among the multiple base stations managed by the first LMF network element, one of the base stations is the base station currently connected to the user equipment, or called the base station where the user equipment is currently located, and is called t...

Abstract

The invention discloses a positioning method of user equipment, an LMF network element and a 5G network. The positioning method comprises the steps that a first LMF network element acquires a positioning request message through a first base station, acquires a positioning result of the user equipment, returns the positioning result to the user equipment through the first base station and the like.According to the invention, the time delay of the positioning request message and the positioning result on the link can be reduced, so that the time required by the user equipment from sending the positioning request message to the positioning result is shorter, and the positioning of the user equipment can be realized more quickly with lower time delay. Since the positioning request message andthe positioning result are directly exchanged between the first LMF network element and the first base station without passing through the AMF network element, the first LMF network element is allowed to be located at a position closer to the user equipment, and the time delay in the positioning process can be further reduced by shortening the physical line distance on the basis of improving thenetwork topology to reduce the time delay. The method is widely applied to the technical field of mobile communication.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a positioning method for user equipment, an LMF network element and a 5G network. Background technique [0002] 5G communication technology can be applied in fields such as unmanned aerial vehicles or robots. These fields are related to the safety of life and property in the production process, and require fast and low-latency positioning of user equipment. According to the current 5G communication network technical standards, positioning The function is mainly realized through the LMF network element. In the prior art, since the design of the data processing process related to the positioning function of the LMF network element is not very reasonable, the time delay in the positioning process is relatively large. [0003] Explanation of terms: [0004] LMF network element: the location management function (Location Management Function); [0005] AMF netwo...
