Abstract: Presented herein are techniques to facilitate user equipment (UE) to UE communications in a mobile network environment. In one example, a method may include provisioning a UE route selection policy (URSP) for each of a first UE and a second UE, wherein each URSP provisioned for each of the first UE and the second UE comprises: a first token that identifies at least one network resource that is to be utilized for a session for each of the first UE and the second UE; and a second token associated with a quality of service (QoS) that is to be provided for each session. The first token can be used to establish a session for each of the first and second UE using the same at least network resource and each session can be provided a QoS level based on the second token.

Abstract: Provided herein are techniques to facilitate radio access network sharing for a Multi-Operator Core Network (MOCN) environment. In one instance, a method may include obtaining, by a radio node of a shared RAN, home mobile network identifiers that are associated with a home access and mobility management function (AMF) in which the home mobile network identifiers are obtained from a first transit AMF that include first priority values and from a second transit AMF that include second priority values. The method may further include obtaining a control plane communication from a user equipment (UE) including a particular home mobile network identifier, identifying the first transit AMF or the second transit AMF that is associated with a highest priority value for the particular home mobile network identifier; and transmitting the communication to the identified transit AMF that is to proxy control plane communications between the UE and the home AMF.

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: The present disclosure provides solutions to registration and discovery of NFs in the vertical 5G networks, at the operator network, as well as handling tasks such as authentication of connecting end terminals at the operator network level. In one aspect, a method includes receiving, at network controller of an operator network and from an end terminal, a request for access to a network function (NF) of a vertical network, the request including a type of the NF in the vertical network; authenticating, at the network controller, the end terminal; upon authenticating the end terminal, identifying, at the network controller, the NF requested by the end terminal based at least on the type of the NF included in the request; and facilitating, by the network controller, access to the NF in the vertical network by the end terminal.

Abstract: The present disclosure is directed to migrating network traffic from a licensed spectrum to an unlicensed spectrum within the same radio access technology (RAT). In one aspect, a method includes identifying a user device connected to a cellular wireless access technology, over a licensed spectrum; determining whether a condition for switching network traffic associated with the user device to an unlicensed spectrum is triggered; in response to determining that the condition is triggered, determining an unlicensed spectrum to move the network traffic to, the unlicensed spectrum being within a same cell as the licensed spectrum or in a different cell compared to a cell in which the licensed spectrum is; and migrating at least a portion of the network traffic to the unlicensed spectrum while maintaining network connectivity of the user device over the cellular wireless access technology.

Abstract: A user device operates a first data session using a first network slice. The user device obtains a trigger notification from a remote application that identifies a second network slice, and the user device determines that the first network slice and the second network slice are mutually exclusive. The user device ends the first data session on the first network slice and initiates a second data session on the second network slice.
