Abstract: Disclosed herein are systems, methods, and computer-readable media for authentication in a multi-cloud cellular service. In one aspect, a method includes receiving, at a controller of a local site within the multi-cloud cellular service, a network connection request from a device, the cloud-based authentication component being a central network component configured to store device credentials and network policies for authenticating devices connecting to the multi-cloud cellular service across all sites associated with the multi-cloud cellular service. In one aspect, the method also includes locally authenticating, by the controller, the device using stored credential information obtained from the cloud-based authentication component prior to losing the connectivity to the cloud-based authentication component.

Abstract: The present disclosure is directed to systems and techniques for providing service continuity for User Equipment (UE) services associated with certain network slices. In one example, the systems and techniques can receive a registration request from a UE, wherein the registration request includes a requested slice, and determine a current network location of the UE. In response to determining that the current network location of the UE does not support the requested slice, one or more additional network locations that support the requested slice can be identified. Location information associated with the one or more additional network locations can be identified and a registration response message can be transmitted to the UE, wherein the registration response message includes location information of an one or more additional Tracking Area Identities (TAIs) or additional Registration Areas (RAs) that support the requested slice.

Abstract: Presented herein are techniques to provide a network-initiated group disconnect for wireless devices belonging to one or more device group(s). In one example, a method may include determining, by a control element of a network, that at least one device group is to be disconnected from the network, wherein the at least one device group comprises a plurality of wireless devices connected to the network; identifying one or more access network radios through which the plurality of wireless devices are connected to the network; and triggering a disconnect command for the at least one device group to be broadcast from each of the one or more access network radios to trigger the plurality of wireless devices to disconnect from the network.

Abstract: A method enables communication between Session Management Function (SMF) and User Plane Function (UPF) instances which are separately deployed behind Network Address Translation (NAT) services. The method includes configuring an SMF or a UPF to initiate an association with a corresponding UPF or SMF. The SMF registers first information with a Network Repository Function (NRF) enabling the remote UPF to communicate with the SMF through a NAT service. The method further includes obtaining second information from the NRF enabling the SMF to communicate with the remote UPF through the NAT service. The method also includes sending an association request to the remote UPF based on the second information and receiving an association response from the remote UPF through the NAT service.

Abstract: A system is provided for supporting roaming between LTE EPC network and 5G network of a first mobile network operator by 5GC network of a second network operator. The system may include the EPC network including a serving gateway in communication with a 4G base station being in the EPC network. The system may also include the 5G network of the first mobile network operator including a vSMF in communication with a 5G base station being in the 5G network of the first network operator. The system may also include the 5GC network of the second network operator including a hSMF. The vSMF is configured to receive a communication from the serving gateway to anchor mobility between the LTE EPC network and the 5G network of the first mobile network operator, and to communicate with the hSMF in the 5GC network of the second network operator using 5G roaming interfaces.

Abstract: A control plane (CP) entity is to adaptively reroute user plane traffic of a mobile node (MN) with use of a segment routing (SR) for IPv6. A message indicating an attachment of the MN to the mobile network is received selecting a first user plane (UP) anchor node. A first set of home network prefixes (HNPs) are allocated to the MN. An IP traffic flow using a first HNP prefix is established between the MN and a correspondent node (CN) along a first network path—defined at least in part by the first UP anchor node and an anchor node of the CN. In response to a handover of the MN, a message indicating a subsequent attachment of the MN is received selecting a second UP anchor node. The second UP anchor node is instructed to host the first HNP prefix previously allocated by the first UP anchor node.

Abstract: In accordance with various embodiments, a method is performed including establishing a first communication session between an application function and a user equipment assigned a first IP address. The method includes determining, by the application function, that the user equipment has changed location. The method includes, in response to determining that the user equipment has changed location, sending, by the application function, a request that the user equipment be assigned a second IP address. The method includes establishing a second communication session between the application function and the user equipment assigned the second IP address.

Abstract: Policy enforcement may be provided. First, a Policy and Charging Enforcement Function (PCEF) server may receive a plurality of network policies along with validity information. The PCEF server may receive a first set of connectivity data associated with a subscriber session. Next, the PCEF server may analyze the first set of connectivity data to determine a first set of policies. The PCEF may then enforce those policies. The PCEF may further receive a second set of connectivity data associated with the subscriber session. The second set of connectivity data may indicate, for example, a change in radio access technology of the subscriber session or a change in location of a subscriber device. Next, the PCEF may analyze the second set of connectivity data to determine a second set of policies to enforce without interacting with a Policy and Charging Rules Function server. The PCEF may then enforce those policies.
Abstract translation: 可以提供政策执行。 首先，策略和计费执行功能（PCEF）服务器可以接收多个网络策略以及有效性信息。 PCEF服务器可以接收与订户会话相关联的第一组连接数据。 接下来，PCEF服务器可以分析第一组连接数据以确定第一组策略。 PCEF可能会执行这些策略。 PCEF还可以接收与用户会话相关联的第二组连接性数据。 第二组连接数据可以指示例如用户会话的无线电接入技术的改变或用户设备的位置的改变。 接下来，PCEF可以分析第二组连接数据以确定不与策略和计费规则功能服务器交互的第二组策略。 PCEF可能会执行这些策略。

Abstract: Disclosed are a system and method for updating a user equipment route selection policy. The method includes receiving, at a home network in communication with a user equipment, an indication that a user of the user equipment desires to connect to a standalone non-public network for an event, receiving service hosting information for the event, revising a user equipment route selection policy at the home network based on the service hosting information to yield an updated user equipment route selection policy and transmitting the updated user equipment route selection policy to the user equipment. The user equipment registers, based on the updated user equipment route selection policy, with the standalone non-public network for the event.
