摘要： A method is provided in one example embodiment and includes receiving at a network element a packet associated with a flow and determining whether a flow cache of the network element includes an entry for the flow indicating a classification for the flow. The method further includes, if the network element flow cache does not include an entry for the flow, punting the packet over a default path to a classifying service function, in which the classifying service function classifies the flow and determines a control plane service function for handling the flow, and receiving from the classifying service function a service path identifier (“SPI”) of a service path leading to the determined control plane service function. The flow is subsequently offloaded from the classifying service function to the network element.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： Presented herein are efficient techniques through which a Third Generation Partnership Project (3GPP) Access and Mobility Management Function (AMF) may retrieve information for a Mobility Management Entity (MME) to support graceful mobility for various inter-Radio Access Technology (inter-RAT) mobility scenarios. In one example, a method includes determining, by an AMF, an inter-RAT mobility event for a user equipment; identifying, by the AMF, an MME associated with the inter-RAT mobility event based, at least in part, on MME information contained in a network database; and transferring context information for the user equipment between the AMF and the MME. In one instance, the network database may be a Network Repository Function (NRF) for a 3GPP Fifth Generation mobile network and the MME information may be associated with an MME network function type stored in the NRF.

摘要： 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.

摘要： In one example, a first connectivity request for a first network connection between a user equipment and a first network is obtained. A control plane serving gateway node for the first network connection is selected. The control plane serving gateway node is co-located with a control plane packet data network gateway node configured to support a second network connection between the user equipment and a second network that is different from the first network. A second connectivity request for the second network connection is obtained. The second network connection is established with the control plane serving gateway node and the control plane packet data network gateway node.
