摘要： Systems, devices, methods, and non-transitory, machine-readable media for uniquely identifying user equipment with a wireless network may include one or a combination of the following. A cellular network core may include a user plane function (UPF). The UPF may collect and store subscription permanent identifier (SUPI) information and/or generic public subscription identifier (GPSI) information corresponding to user equipment (UE) having an IP address. In response to a request, the cellular network core may execute a conditional process based at least in part on the UPF using the SUPI information and/or the GPSI information as part of the conditional process to respond to the request. The request may be for GPSI information corresponding to the UE. An external IP address of the UE may be provided along with the request. Upon completion of the conditional process, the cellular network core may return the GPSI information corresponding to the UE.

摘要： Various arrangements for obtaining a cellular network address are presented herein. A request can be received from a network function residing outside of a cellular network core. The request can indicate an external Internet Protocol (IP) address associated with a piece of user equipment (UE). A network exposure function (NEF) of the cellular network core can route the request to a user plane function (UPF) of the cellular network core. The UPF can determine a cellular network address for the UE that corresponds to the external IP address. The NEF can transmit an indication of the determined cellular network address to the network function.

摘要： Embodiments provide novel approaches to handling network slice groups in access stratum and non-access stratum communications in a cellular communication network. Novel slice identification schema can support group-level identification of groups of network slices without individually listing the network slices. Some embodiments implement a slice identifier that supports wildcard slice/service type (SST) options and/or wildcard slice differentiator (SD) options to support wildcard-enabled slice groups. Some embodiments enable use of such wildcard-enabled slice groups in context of unified access control. Some embodiments introduce a novel criteria type to unified access control to expressly support flexible slice grouping.

摘要： A disclosed method may include (i) receiving, by a centralized unit-control plane node within a telecommunications network, an indication for a user equipment to establish a session at least in part by being assigned a centralized unit-user plane node, (ii) forwarding, by the centralized unit-control plane node to a radio access network repository function within a corresponding radio access network, centralized unit-user plane discovery information for the user equipment, (iii) receiving, from the radio access network repository function, in response to forwarding the centralized unit-user plane discovery information, identifying information for at least one centralized unit-user plane node, (iv) assigning, by the centralized unit-control plane node and based on the received identifying information for the at least one centralized unit-user plane node, a specific centralized unit-user plane node to the user equipment. Related systems and computer-readable mediums are further disclosed.

摘要： Embodiments support non-homogeneous distribution of networks slices over a registration area (RA) in a manner that helps to ensure proper signaling of user equipment (UE) re-registration in cases of conditional network slices. For example, an RA is established to include conditional network slices that are available in only a subset of the tracking areas (TAs) of the RA. Each conditional network slice can be associated with a re-registration condition that explicitly or implicitly dictates whether the UE must re-register for that network slice prior to utilizing the network slice and upon entering a TA in the RA where the network slice is supported. For example, the re-registration condition can relate to whether the network slice is subject to Network Slice Admission Control (NSAC) and/or Network Slice Specific authentication & Authorization (NSSAA).

摘要： Providing expandable network slices that may increase in geographic coverage area on-demand include includes enabling a user equipment device (UE) to operate on a network slice instance on a first Next Generation Node B (gNB) associated with a first cell in a 5G NR cellular network. While the UE is operating on the network slice instance, the system detects mobility of the UE that may require handover from the first gNB associated with the first cell on which the UE is operating to a second gNB associated with a second cell, in which the first gNB and second gNB belong to different tracking areas. While the UE is operating on the network slice instance, the system deploys and activates the same network slice instance on the second gNB that is associated with the second cell based on the detection of mobility of the UE.

摘要： Embodiments are directed towards systems and methods for downlink access control in a communications network. An example method includes a base station receiving a request for downlink (DL) communication with a user equipment (UE), and the base station performing the following actions without communicating with the UE regarding the request for the DL communication: determining an unavailability of a resource required for the DL communication; responsive to the determined unavailability, sending a rejection of the request; determining an availability of the resource; and responsive to the determined availability, sending an indication of the availability of the resource required for the DL communication.

摘要： A disclosed method may include (i) receiving a message including first buffering-relevant information relating to an ability of a specific centralized unit-user plane node to perform a buffering procedure, (ii) evaluating the first buffering-relevant information against second buffering-relevant information indicating at least in part whether an item of user equipment is an appropriate candidate for the buffering procedure, and (iii) assigning the specific centralized unit-user plane node based at least in part on evaluating the first buffering-relevant information against the second buffering-relevant information. Related systems and computer-readable mediums are further disclosed.
