Abstract: Systems and methods are provide to bring network capability awareness to steering of roaming (SoR). A home network includes a capabilities list of visited networks and their associated with the network capabilities. For SoR, he user equipment (UE) maintains a roaming partners list (RPL). The RPL provides a list of visited networks arranged in order of priority/preference (e.g., the first visited network in the RPL has first priority). The first visited network receives a registration request from the UE and relays a corresponding authentication request to the home network. The visited network in the RPL can be reordered when the UE requires a network capability not supported by the first visited network in the RPL, as indicated by the capabilities list. Depending on the implementation, the UE or the home network can make this decision to reorder the RPL.

Abstract: Presented herein are techniques to facilitate providing slice attribute information to a user equipment (UE) for one or more slice types with which the user equipment is allowed to establish one or more session(s). In one example, a method may include obtaining, by a network element, a registration request for connection of a UE to a mobile network; performing an authentication for connection of the UE to the mobile network; and upon successful authentication, providing, by the network element, a registration response to the UE, wherein the registration response identifies one or more network slice types with which the UE is authorized to establish a session and the registration response identifies one of: attribute information for each of the one or more network slice types or network location information from which attribute information for each of the one or more network slice types is to be obtained.

Abstract: A Radio Access Network (RAN) node configures a User Equipment (UE) to provide measurement results for private wireless networks in the neighborhood of the UE. The RAN node registers the UE with a computer network and provides location information about the UE to an Application Function (AF) connected to the computer network. The RAN node obtains a partial identifier that specifies a range of private wireless networks selected by the AF, and sends a request to the UE for measurements associated with the range of private wireless networks.

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: The present technology involves system, methods, and computer-readable media for establishing mobility of user equipment (UEs) or mobile from congested new radio (NR) cells to un-congested Long-Term Evolution (LTE) cells. For operators that deploy both LTE cells and NR cells, the UEs can move from congested NR cells to un-congested LTE cells but can also be handed back into un-congested NR cells.

Abstract: A control plane (CP) function for mobility management may receive, from a user equipment (UE), a message which indicates a registration request for registration to a network slice. The CP function may select, as an allowed slice ID, a first slice ID of a first network slice in which to register the UE. The first slice ID has a slice/service type (SST) value indicating an SST and a first slice differentiator (SD) value associated with a first level of service to be provided. The CP function may alternatively select, as the allowed slice ID, a second slice ID of a second network slice in which to register the UE based on unavailability of the slice type associated with the first level of service. The second slice ID has the SST value indicating the slice type and a second SD value associated with a second level of service to be provided.

Abstract: Provided herein are techniques to facilitate location-specific wireless local area network (WLAN) offload restrictions for user equipment based on wireless wide area network (WWAN) radio band(s). In at least one example, a method performed by an authentication server of a WLAN may include, for a user equipment (UE) that is connected to an NR radio band of a WWAN and is seeking to connect to the WLAN, querying a subscription element of the WWAN to obtain a location indicator and an NR radio band indicator for the UE; determining, based on the location indicator and the NR radio band indicator, whether the UE is allowed or required to offload to the WLAN; and based on determining that the UE is allowed to offload from the WWAN to the WLAN, facilitating a WLAN association response message to be sent to the UE for offloading the UE to the WLAN.

Abstract: Disclosed herein are systems, methods, and computer-readable media for causing an user equipment (UE) to connect to a non-public network (NPN) while meeting time and location requirements. In one aspect, a method includes receiving, by the UE and from a home public land mobile network (h-PLMN), a steering of roaming update providing a steering of roaming record. In one aspect, the UE, is configured based on the steering of roaming record, to connect to the non-public network (NPN) when a context of the UE meets time and location requirements. In one aspect, the method includes establishing, by the UE, a session with the NPN when the context of the UE meets the time and location requirements.

Abstract: Disclosed herein are systems, methods, and computer-readable media for enhancements to 5G Access Transport Steering Switching & Splitting (ATSSS) rules. In one aspect, a method includes receiving, at a network controller, a request for a Multi-Access Protocol Data Unit (MA-PDU) session from a user device, the request including a “Multi access multi PLMN” flag for requesting multiple Public Land Mobile Network (PLMN) sessions; generating, at the network controller, an access transport steering switching and splitting (ATSSS) rule for steering traffic associated with the user device between at least two PLMNs once the multiple PLMN sessions are established between the user device and the at least two PLMNs; and sending the steering rule to the user device to be used for splitting uplink network traffic transmitted between the user device and the at least two PLMNs.

Abstract: A system and method for dynamic enablement of a RLC mode of a Data Radio Bearer (DRB) based on UE radiofrequency (RF) conditions. A threshold value for a network characteristic is provided to a gNodeB. Changes in the network characteristic correlates to changes in RF channel conditions of the UE. The trigger configures the gNodeB to identify when the network characteristic meets the threshold value for selectively controlling operation of the gNodeB at one of a plurality of different operation modes including an initial radio link control (RLC) mode based on the network characteristic. A Protocol Data Unit (PDU) session is established with the gNodeB operating in an initial RLC mode with the possibility to dynamically switch to a different RLC mode based on RF channel conditions.
