Abstract: An enterprise private network includes a simplified Third Generation Partnership Project (3GPP) core architecture for interworking between an Evolved Packet System (EPS) and a Fifth Generation (5G) system (5GS). The architecture includes an Evolved Packet Core (EPC) control plane (CP) (EPC CP) unit and a 5G core (5GC) CP (5GC CP) unit. The 5GC CP unit receives, from the EPC CP unit via an N26 interface, a message indicating a forward relocation request responsive to an indication of a handover of a Packet Data Network (PDN) connection at a user plane node from the EPS to the 5GS. The 5GC CP node establishes a Protocol Data Unit (PDU) session corresponding to the PDN connection based on PDN connection information in the message, which includes establishing a Quality of Service (QoS) Flow corresponding to an EPS bearer, and manages the PDU session at the user plane node.

Abstract: Presented herein are techniques to facilitate extending a multiple access Protocol Data Unit (PDU) session and Access Traffic Steering, Switching, and Splitting Low-Layer (ATSSS-LL) policies to an enterprise network. In one example, a method may include obtaining a request for an ATSSS-LL policy for a user equipment (UE) for establishing a multiple access protocol data unit session for the UE via a wireless wide area access network for an enterprise network; and providing to the UE one or more ATSSS-LL rules for the ATSSS-LL policy, an Internet Protocol (IP) address for the multiple access protocol data unit session for the UE, and an identifier for the multiple access protocol data unit session for the UE in which the IP address is utilized for a wireless local area access network connection for the UE established via a wireless local area access network of the enterprise network.

Abstract: Presented herein are techniques to facilitate fast roaming between a mobile network operator-public (MNO-public) wireless wide area (WWA) access network and an enterprise private WWA access network. In one example, a method is provided that may include generating, by an authentication node, authentication material for a user equipment (UE) based on the UE being connected to a public WWA access network, wherein the public WWA access network is associated with a mobile network operator, and the authentication node and the UE are associated with an enterprise entity; obtaining, by the authentication node, an indication that the UE is attempting to access a private WWA access network associated with the enterprise entity; and providing, by the authentication node, the authentication material for the UE, wherein the authentication material facilitates connection establishment between the UE and the private WWA access network.

Abstract: Techniques are described to provide to provide service allocation across multi-managed heterogeneous networks. In one example, a method includes determining, by an application network policy controller, service information for an application, wherein the application communicates with an application server. The method may further include identifying one or more network domains of a plurality of network domains to provide network connectivity between the application and the application server based, at least in part, on service qualifiers and context information for the plurality of network domains and the service information for the application; generating an application policy for the application, wherein the application policy identifies, at least in part, the one or more network domains to provide network connectivity between the application and the application server; and communicating the application policy to the one or more identified network domains to provide network connectivity between the application and the application server.

Abstract: In one example, an authentication server generates a Chargeable User Identity (CUI) for a User Equipment (UE) based on a first indication of an identifier obtained from the UE based on communications of the UE over a first network interface of a system. The authentication server obtains a second indication of the identifier based on communications of the UE over a second network interface of the system. In response to obtaining the second indication of the identifier, the authentication server determines that the UE is attempting to communicate over the second network interface. In response to determining that the UE is attempting to communicate over the second network interface, the authentication server uses the CUI for further communications of the UE over the second network interface.
