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: A method, computer system, and computer program product are provided for obfuscating and storing data. A data object is obtained comprising data for storing to a plurality of distributed ledgers. Sequence information is obtained indicating a number of a plurality of data portions into which the data object is divided, and instructions for storing the plurality of data portions to the plurality of distributed ledgers. The plurality of data portions is generated by dividing the data object according to the number. The plurality of distributed ledgers are determined to store the plurality of data portions based on the instructions indicated by the sequence information. The plurality of data portions is stored across the plurality of distributed ledgers by accessing the plurality of distributed ledgers, wherein each data portion is stored to a particular distributed ledger of the plurality of distributed ledgers according to the instructions indicated by the sequence information.

Abstract: In one example, a Network Policy Function (NPF) obtains a first identifier for a User Equipment (UE) based on communications between the UE and a first access network of a system, and an Internet Protocol (IP) address used by the UE to communicate over the first access network. The NPF obtains a second identifier for the UE based on communications between the UE and a second access network of the system. The NPF determines that the UE used the IP address to communicate over the first access network of the system based on a correlation between the first identifier for the UE and the second identifier for the UE. The NPF provides the IP address to the UE, and the UE uses the IP address to communicate over the second access network.

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: 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.
