Problems solved by technology
Due to the large number of terminals, and multiple applications running on the terminals may send positioning requests separately, the AMF network element will receive a large number of positioning requests, and responding to these positioning requests will increase the load on the AMF network element, and each terminal Less efficient to get location services
Moreover, limited by the configuration of AMF network elements in the prior art, LMF network elements cannot move in and out of the network flexibly. In areas where LMF network elements are not well planned, AMF network elements may not be assigned to LMF network elements for terminals, resulting in terminals being unable to obtain The case for location services

Embodiment Construction
[0052] In this embodiment, the communication network may refer to a 5G communication network or a more advanced network. The communication includes an AMF network element, multiple LMF network elements and a network element serving as an LMF management center, and two specific LMF network elements among the multiple LMF network elements are the first LMF network element and the second LMF network element. Wherein, AMF is an abbreviation of Access and Mobility Management Function, and LMF is an abbreviation of Location Management Function.
[0053] In this embodiment, the network element serving as the LMF management center may be a dedicated network element, or a network element with other functions also serving as the LMF management center.
[0054] In this example, refer to figure 1 , the LMF management center receives registration requests from LMF network elements such as the first LMF network element and the second LMF network element, and the registration request includes...

The invention discloses a positioning method for a terminal in a communication network, a network system, a computer device and a storage medium. The positioning method includes generating an AMF network element and sending a request for assigning an LMF network element to the LMF management center, and the LMF management center finds out the first The LMF network element returns the address information, the AMF network element sends a positioning request to the first LMF network element according to the address information, the first LMF network element sends the location information of the terminal to the LMF management center, and the LMF management center reassigns the LMF network element to the terminal, etc. step. The invention enables the LMF management center to share the load generated by the AMF network element for distributing the LMF network element to the terminal, avoiding the excessive load of the AMF network element, and improving the light weight of the network function in the communication network. As long as there is an available LMF The network element can ensure that the terminal can be allocated to the LMF network element that can provide the positioning service. The invention is widely used in the field of communication network technology.
Description
technical field [0001] The invention relates to the technical field of communication networks, in particular to a positioning method for a terminal in a communication network, a network system, a computer device and a storage medium. Background technique [0002] At present, in communication networks such as the 5G core network, LMF network elements are used to determine the location of terminals connected to the 5G core network, thereby providing positioning services for the terminals. In the prior art, when a terminal needs to obtain a positioning service each time, the terminal sends a positioning request to an AMF network element, and the AMF network element selects a suitable LMF network element for the terminal according to the positioning request. Due to the large number of terminals, and multiple applications running on the terminals may send positioning requests separately, the AMF network element will receive a large number of positioning requests, and responding t...
