    Abstract: An example method is provided in one example embodiment and includes receiving, by a user equipment device, a list including at least one location identifier associated with an area for location reporting and an area identifier identifying the area for location reporting. The method further includes receiving a location identifier broadcast by a wireless network element, and determining whether the broadcast location identifier matches the at least one location identifier associated with the area for location reporting. The method further includes sending a location reporting message by the user equipment device to a first network node when it is determined that the broadcast location identifier matches the at least one location identifier associated with the area for location reporting. The location reporting message is indicative of the user equipment device either entering or exiting the area for location reporting.

    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 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: Techniques are described herein for network slice support of respective transport protocols. In one example, a session management function obtains, from a user equipment, a request for a network slice identifier in a network that includes a plurality of network slices each configured to support a respective transport protocol. In response to the request, the session management function identifies a first transport protocol of the respective transport protocols by which the user equipment is to communicate. Based on the first transport protocol, the session management function identifies a first network slice of the plurality of network slices by which the user equipment is to communicate. The first network slice is configured to support the first transport protocol. The session management function provides the network slice identifier to the user equipment. The network slice identifier corresponds to the first network slice.

    Abstract: A control plane of a network, including radios of a radio access network controlled by the control plane and user plane functions controlled by the control plane, establishes first and second protocol data unit (PDU) connections each to handle the same flows of traffic for ultra-reliable low latency communications (URLLC) from user equipment to a data network through first and second source radios, respectively. Due to mobility of the user equipment, the control plane relocates the flows from the first and second source radios to first and second target radios, respectively. To relocate the flows, the control plane receives from the first target radio a notification that identifies flows that cannot be activated on the first target radio. In response to the notification, the control plane commands the first target radio to prioritize the flows that cannot be activated above remaining ones of the flows.
