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: There are provided measures for enabling/realizing external steering of access traffic multipath communication in a mobile communication system, e.g. an external access traffic multipath communication steering function. Some such measures include that a session management function element or instance in a mobile communication system initiates control of establishment of at least one user plane session for access traffic multipath communication, obtains communication information of an external steering function element or instance to be used for steering access traffic multipath communication in the at least one user plane session, creates access traffic multipath communication rules, forwarding action rules and multi access rules for access traffic multipath communication in the at least one user plane session, and provides the access traffic multipath communication rules and the communication information of the external steering function element or instance to the communication function element or instance.

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: Techniques for providing distributed NAS layer termination points within a communication network. A network entity assigns a non-access stratum temporary identifier to a user device. The non-access stratum temporary identifier is associated with a non-access stratum termination point, and wherein a type of non-access stratum termination point is based at least in part on an apparatus type configured to handle one or more non-access stratum messages. The network entity causes the user device to be provided with the non-access stratum temporary identifiers.

Abstract: Methods, apparatuses and computer readable medium for user plane function control for multicast transport. A method includes sending (300) a session establishment request to a user plane function requesting the user plane function to apply multicast and supply identifiers for outgoing packets. The method also includes receiving (305) from the user plane function a multicast response comprising the requested identifiers. The method also includes establishing (605) a multicast tunnel with a network node.
