Abstract
Disclosed in the present application are a method for selecting a location management function and a device, which are used to ensure that, in a 5G location network architecture, a UE can quickly redirect to a location management function (LMF) entity after moving so as to meet high-precision and low-latency location requirements of the 5G location network architecture. The method includes: determining to trigger the updating of an LMF entity, and executing a process of selecting a new LMF entity; and executing a process of redirecting to the new LMF entity.
Claims29
A method for selecting a location management function (LMF), applied to an access and mobility management function (AMF) entity/mobility management entity (MME) corresponding to a terminal in a process of moving across nodes, and comprising:
- determining to trigger updating of an LMF entity, and executing a process of selecting a new LMF entity;
- and
- executing a process of redirecting to the new LMF entity.

A method for selecting a location management function (LMF), applied to a source node in a process that a terminal moves across nodes, and comprising:
- executing a process of selecting a local location management function (L-LMF) of a target node as a new LMF entity in a case of determining that the terminal moves across the nodes;
- and
- executing a process of redirecting to the new LMF entity.
27-28. (canceled)
A method for selecting a location management function (LMF), applied to a node where a new LMF entity is located in a process that a terminal moves across nodes, and comprising:
- receiving a message requesting to use a local location management function (L-LMF) as the new LMF entity;
- and
- determining the L-LMF as the new LMF entity, and sending a response message carrying an undergoing related location service flow.
