Abstract: In one illustrative example, a user equipment (UE) policy may be communicated to a UE. The UE policy may be a UE Route Selection Policy (URSP) which includes a policy rule that associates an application and/or traffic thereof with a routing policy comprising an indicated radio access technology (RAT) type for 3GPP access. When the UE operates to communicate the traffic in a communication session for the application via non-3GPP access, a message which indicates an attach request with a request type indicating “handover” may be received from the UE via a selected radio access network (RAN) corresponding to the indicated RAT type. The message is for triggering a handover of the communication session for the application from the non-3GPP access to the 3GPP access. In one scenario, when Voice over NR (VoNR) is unavailable, the indicated RAT type of the routing policy may be set to indicate an E-UTRAN.

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: Methods are provided which indicate availability of the same service on a different access network. In these methods, the network controller generates an identifier for each of one or more services provided by a wireless local access network (WLAN). The identifier is associated with a particular service which is also provided by a private radio network. The network controller provides to an access point the identifier to be broadcast to one or more user devices of the WLAN to connect to the particular service via the private radio network. A mobility management entity receives a request from a user device to connect to the private network, where the request includes an identifier associated with a particular service provided to the user device in the WLAN and based on the identifier, the mobility management entity enables the particular service to be provided to the user device via the private radio network.

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.

Abstract: A network function selectively supports a mobile device with network settings appropriate for the device context of the mobile device. The network function obtains a device profile for the mobile device, which identifies multiple device groups, with each device group being associated with a corresponding set of network settings. The network function selects a device group among the device groups in the device profile based on a device context of the mobile device. Responsive to a notification of the mobile device in a different device context, the network function supports the mobile device with a different set of network settings that cause a Session Management Function (SMF) to reconfigure the user plane for the mobile device.

Abstract: A Radio Access Network (RAN) element provides an internet indication to a User Equipment (UE) to enable the UE to quickly obtain internet access. The RAN element determines that the RAN element is connected to at least one gateway that provides public internet access, and broadcasts an internet indication. The RAN element determines that the UE has requested public internet access via the RAN element and provides the UE with public internet access.

Abstract: In one illustrative example, a user plane (UP) entity for use in a mobile network may receive a data packet from a user equipment (UE) operative to communicate in one or more sessions via a serving base station (BS) (e.g. eNB or gNB) of the mobile network. The UP entity may detect, in a header (e.g. SRH) of the data packet, an identifier indicating a new serving BS or session of the UE. The identifier may be UE- or BS-added data (e.g. iOAM data) that is inserted in the header by the UE or BS. In response, the UP entity may cause a message to be sent to an analytics function (e.g. a NWDAF) to perform analytics for session or flow migration for the UE.

Abstract: A mobile network is operative to perform a quota validation procedure in relation to a maximum number of user equipments (UEs) permitted in a network slice. In one illustrative example, a control plane (CP) function of the mobile network may receive, from the UE, a message which indicates a registration request for registration and includes a slice ID of the network slice. The CP function may manage a registration procedure for assigning resources of the network slice to the UE. The CP function may alternatively manage the registration procedure to refrain from assigning the resources of the network slice to the UE, at least for a delay time period, based on identifying that an indication of the UE indicates an expected delay in use of service in the network slice. The indication may be included in the message and indicate the delay time period of the expected delay.

Abstract: A control plane function node may be used in a Fifth Generation (5G) Non-Standalone (NSA) architecture having Radio Access Network (RAN) level interworking between a Long-Term Evolution (LTE) RAN and a 5G New Radio (NR). The node obtains usage report data which are based on traffic of a user equipment (UE) via primary and secondary Radio Access Technologies (RATs). The node also obtains secondary RAT usage report data which are based on traffic of the UE via the secondary RAT. The node constructs a message which indicates a request for charging based on the usage report data and the secondary RAT usage report data. In constructing the message, the node populates, in association with a corresponding rating group and usage data of the UE, an identifier of a flow or bearer associated with secondary RAT usage, together with the secondary RAT usage report data.

Abstract: Presented herein are techniques to facilitate visited network selection by a user equipment (UE) based on slice considerations. In one example, a method may include requesting, by a UE that is roaming among a plurality of visited mobile networks, registration for a network connection associated with a slice type; obtaining, by the UE from home mobile network for the UE, a priority for each of the plurality of visited mobile networks and an indication of one or more slice types provided by each of the plurality of visited mobile networks; selecting, by the UE, a highest priority visited mobile network of the plurality of visited mobile networks that provides the slice type; and establishing, by the UE, the network connection with the highest priority visited mobile network of the plurality of visited mobile networks that provides the slice type.
