Abstract: Disclosed in the present application are a method and a device for selecting a local location management function (L-LMF) entity, which are used for ensuring that, under a 5G localization network architecture, UE can use the L-LMF entity of a non-serving RAN node after moving, to satisfy the localization requirements of the 5G localization network architecture for high precision and low time delay. The method includes: upon reception of a localization request message sent by an access and mobility management function (AMF) entity/mobility management entity (MME), starting to execute a process of directing of the UE to the L-LMF entity of a non-serving node; and providing a localization service for the UE by mutually transmitting with the UE a transmission message carrying relevant localization information.
