Abstract: According to certain embodiments, a terminal device may receive location service user plane (LCUP) assistance information in a control plane (CP) positioning protocol signaling. The LCUP assistance information includes at least one of addressing information of an LCUP function instance, and security information for establishing an user plane (UP) session between the terminal device and the LCUP function instance. The LCUP function instance is associated with a location management function (LMF) selected for serving the terminal device. The terminal device can establish a secured UP connection between the terminal device and the LCUP function instance using the LCUP assistance information so as to perform a UP positioning operation using the LCUP function instance. The terminal device can ensure the UE establishes a secured connection with the LCUP associated with the serving LMF, thereby CP location operation through the UP interaction between the terminal device and the LUCP associated with LMF.

Abstract: A PRU requests registration with a cellular network, participates in a procedure to locate the PRU within the network, and associates itself as a PRU with network element(s). A repository receives information for a PRU describing at least a position of the PRU, and stores this. In response to a request by a requesting network element for positioning information of the PRU, the repository sends at least part of the information for the PRU to the network element. A network element implementing an LMF receives, from a first network element, a request for positioning of a target UE, and selects a PRU serving the target UE. The network element receives a first location of the target UE and determines a final location of the target UE considering position information of the PRU and the first location of the target UE, and provides the final location to the first network element.

Abstract: An apparatus comprising circuitry configure to: receive a location request for a location of at least one user equipment, the location request comprising an identifier associated with a group of user equipment or information for determining the identifier associated with the group of user equipment. The circuitry is further configured to, based on determining that the at least one user equipment belongs to the group of user equipment, transmit, towards a network repository function, a discovery request for causing the network repository function to discover and select, based on the identifier associated with the group of user equipment, a location management function that serves the at least one user equipment, the discover request comprising the identifier associated with the group of user equipment and receive, from the network repository function, the identifier of location management function that serves the user equipment
