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: Techniques are provided for operator specific customization of a network service configuration. In some embodiments, an operator defines a mapping between an application executing on a user equipment (UE) and a network service configuration. In some embodiments, the network service configuration indicates whether the application is to be supported via a UPF instance located within the core network or deployed at a network edge. The mapping is then provided to the UE, and passed back to the core network, for example, when the UE establishes a connection on behalf of the UE application. The core network then supports the UE application consistent with the configuration specified by the mapping.

Abstract: Disclosed are embodiments that leverage a central control plane of a managed 5G network service architecture across multiple serviced tenants by deploying tenant specific user plane function (UPF) and gNB components within tenant managed compute infrastructure. To enable this architecture, the disclosed embodiments assign gNBs and UPF instances to specific tenants and communicate those assignments to core components. Policies can be defined and applied to specific tenants from the central control plane. Inbound data routing to a specific tenant is accomplished by referencing a data store in the control plane that identifies which gNBs are assigned to a tenant associated with the incoming data. Those gNBs are then paged to service the incoming data.

Abstract: A network slice controller obtains health information of an active network slice provided by a first vendor and health information of a set of backup network slices provided by a second vendor. The network slice controller evaluates, using a set of policies corresponding to management of the active network slice, the health information of the active network slice to determine whether the active network slice has failed. As a result of the failure of the active network slice, the network slice controller identifies one or more backup network slices of the set of backup network slices to serve as new active network slices. The network slice controller activates these one or more backup network slices to serve as the new active network slices for the network.

Abstract: Various implementations disclosed herein enable programming user plane gateway controllers over enhanced N9 interfaces. In various implementations, a method of gateway controlling is performed by a computing device including one or more processors, and a non-transitory memory. In various implementations the method includes determining, by a first packet gateway controller connected to a first session manager device, that a user equipment moved to a geographical area that is served by a second session manager device. In some implementations, the method includes receiving, by the first packet gateway device, a set of information for a second packet gateway device. In some implementations, the method includes transmitting, by the first packet gateway device, a session establishment request via a first network interface to the second packet gateway controller using segment routing via a second network interface.

Abstract: In one aspect, a method of supporting enhanced UE policies that control which access technologies and the number of access technologies a user equipment can access beyond a single 3GPP connection and a single non-3GPP connection, the method including registering, by a user equipment, to a 3GPP network, wherein the registering includes an indication that the user equipment supports multi-access packet data unit (MA-PDU) sessions; receiving, by the user equipment, a UE policy for a first application permitting the user equipment to access at least three access technologies for communications while accessing the first application, wherein the UE policy is received from an access mobility function (AMF) of the 3GPP network; and determining, by the user equipment, one or more of the access technologies permitted in the UE policy for the first application to use to establish protocol data unit (PDU) session with the first application.

Abstract: Presented herein are techniques to provide selective network slice authentication and authorization in a mobile network environment. In one example, a method may include obtaining, by an access management element of a mobile network, a registration request from a user equipment, wherein the registration request identifies a plurality of network slices with which the user equipment seeks authentication; determining that if authentication for the user equipment with a first network slice is successful, authentication for the user equipment with one or more other network slices can be skipped; and upon successful authentication for the user equipment with the first network slice, skipping authentication for the user equipment with the one or more other network slices.

Abstract: Techniques and mechanisms for use in facilitating home network assisted concurrent access to network slices in multiple visited public land mobile networks (VPLMNs) are described. A control plane (CP) function for mobility management may receive, from a UE (e.g., configured without dual connectivity), a message which indicates a registration request for registration using a first network slice and a second network slice. The CP function may manage registration for the UE in response to the registration request. The CP function may receive, from the UE, a message which indicates a request for establishing a protocol data unit (PDU) session using the second network slice which is not supported or available in the first VPLMN. The CP function may forward the request for establishing the PDU session to an application function (AF) for managing establishment of the PDU session for the UE using the second network slice in a second VPLMN.
