Abstract: Aspects of the disclosed technology provide ways to report User Equipment (UE) device locations in a 5G network for the purpose of redirecting application traffic from proximately located Data Networks (DNs). In one aspect, the disclosed technology encompasses a process for conveying User Equipment (UE) information to an Application Function (AF), the process includes steps for receiving, at an intermediate-User Plane Function (I-UPF) entity, User Equipment (UE) uplink data from a Radio Access Network (RAN), determining if sharing of location information or application information associated with the UE is restricted, and encapsulating first location metadata or application metadata in an SRv6 packet if the sharing of location information or application information is not restricted. Systems and machine-readable media are also provided.

Abstract: In a Fifth Generation (5G) network having an enhanced SBA (eSBA) architecture, a message with a header used to signal binding information (e.g. HTTP custom header for 3gpp-Sbi-Binding) may be received at a recipient NF (service) instance in a direct communication or via a service communication proxy (SCP) in an indirect communication. A binding indication comprising an address of an NF (service) instance may be obtained from the header. One or more alternative binding indications comprising one or more alternative addresses of one or more alternative NF (service) instances may also be obtained from the header. The one or more alternative NF (service) instances may be equivalent NFs (services) of the same NF (Service) Set as the NF (service) instance. The address may be used for communication of messages to the NF (service) instance, and the one or more alternative addresses may be used for load balancing or backup failure.

Abstract: A Network Exposure Function (NEF) relays a trigger from a remote application function to a user device and causes the user device to switch between mutually exclusive network slices. The NEF stores a mapping associating device modes with network slices. The NEF also determines that a user device is operating in a first device mode using a first network slice. The NEF obtains a trigger from the remote application function identifying the user device and a second device mode. The NEF determines that the second device mode is associated with a second network slice that is mutually exclusive to the first network slice. The NEF provides a notification to the user device, causing the user device to end a first data session on the first network slice and to initiate a second data session on the second network slice.

Abstract: A network function (NF) entity in a communication network receives User Plane Function (UPF) registration information for a plurality of UPFs, the registration information including a respective network attribute for each UPF. The NF entity associates each UPF with a corresponding network based on the respective network attribute, and map one or more User Equipment (UE) to the corresponding network based on a security policy to create a UE-to-network table. The NF further receives a request to establish a session for a subsequent UE, the request including a subsequent UE identifier, and determine an access permission for the subsequent UE to access the corresponding network based on the subsequent UE identifier and the UE-to-network table. The NF selects one UPF from the plurality of UPF to service the session for the subsequent UE based on the access permission, and an association between the one UPF and the corresponding network.

Abstract: In one example, an Access Point (AP) configures a first mapping of a first cellular network connection to a first local access network group, and further configures a second mapping of a second cellular network connection to a second local access network group. The AP determines whether a user device is authorized to use the first cellular network connection or the second cellular network connection. If the user device is authorized to use the first cellular network connection, the AP associates, for the user device, a first user device identifier with the first local access network group. If the user device is authorized to use the second cellular network connection, the AP associates, for the user device, a second user device identifier with the second local access network group.

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: Techniques are presented in which a new information element signaling priority of a management entity is included in a setup (e.g., S1-Setup) response or configuration update message sent by a management entity to a base station entity. The base station entity interprets this priority information along with the relative capacity information in an appropriate way to load-distribute the traffic/calls to highly preferable management entity instances (at a local site) when they are available, and switchover/failover to lower preference management entity instances (at a remote site) when there is a local site outage/failure or insufficient capacity in a geo-resilient pooled network.
