The core module of LCS in 5G is the LMF, which manages the support of various posi-tioning services. During the UE positioning process, the LMF first identifies the position-ing methods and invokes the positioning tasks in the UEs and the related base stations in the. . In this paper, we summarize the evolution of positioning standards in the Third Generation Partnership Project (3GPP) and briefly introduce the new positioning standards in 5G NR (New Radio), which include new positioning requirements, the general positioning structure, new positioning reference. . Receive configuration parameters of the positioning reference signal sent by the LMF entitywherein, the configuration parameters of the positioning reference signal include: a transmission period of the positioning reference signal, and/or, the positioning within each transmission period The offset. . AMF: The AMF is a key component in 5G networks. It manages mobility, session management, and security for user devices. UDM: The UDM handles user-related data, including authentication, authorization, and subscription information. RAN: The RAN connects user devices to the core network. It includes. . Abstract—Despite the large attention achieved by 5G localiza-tion in standardization bodies, the integration of 5G network function modules designed for localization lacks experimental work. In this work, we. . With Release 16 of the 3GPP, finalized in 2021, a significant standardization effort has taken place for positioning in 5G networks, especially in terms of physical layer signals, measurements, schemes, and architecture to meet the requirements of a wide range of regulatory, commercial and. . The AMF receives a request for some location service associated with a particular target UE from another entity (e., GMLC or UE) or the AMF itself decides to initiate some location service on behalf of a particular target UE (e., for an IMS emergency call from the UE) as described in TS 23.
