Abstract: Techniques for using Network Address Translation (NAT), Mobile Internet Protocol (MIP), and/or other techniques in conjunction with Domain Name System (DNS) to anonymize server-side addresses in data communications. Rather than having DNS provide a client device with an IP address of an endpoint device, such as a server, the DNS instead returns a random IP address that is mapped to the client device and the endpoint device. In this way, IP addresses of servers are obfuscated by a random IP address that cannot be used to identify the endpoint device or service. The client device may then communicate data packets to the server using the random IP address as the destination address, and a gateway that works in conjunction with DNS can convert the random IP address to the actual IP address of the server using NAT and forward the data packet onto the server.

Abstract: Presented herein are techniques to facilitate delivering standalone non-public network (SNPN) credentials from an enterprise authentication server to a user equipment (UE) using an Extensible Authentication Protocol (EAP) process. In one example, a method may include determining, by an authentication server of an enterprise, that a UE for the enterprise is to receive credentials to enable the UE to connect to a SNPN of the enterprise in which the determining is performed based, at least in part, on connection of the UE to an access network that is different than the SNPN for the enterprise; and performing an authentication process with the UE by the authentication server in which the authentication process includes providing the credentials to the UE via a first authentication message and obtaining confirmation from the UE via a second authentication message that indicates successful provisioning of the credentials for the UE.

Abstract: Presented herein are techniques to facilitate the configuration of hybrid cells to support shared cell and unique cell operating modes for user equipment. In one example, a method may include obtaining a registration request for a user equipment (UE) in which the mobile network includes a radio access network (RAN) comprising a plurality of radio units (RUs) in which each RU provides a shared cell that is shared with at least one other RU and each RU also provides a unique cell that is not shared with any other RU. The method may further include determining an operating mode for the UE in which the operating mode indicates whether the UE is to operate in a shared cell or a unique cell operating mode, and facilitating connection of the UE to one of the shared cell or the unique cell of an RU based on the operating mode.

Abstract: Presented herein are techniques to provide an operator-encrypted application specific user equipment (UE) route selection policy (URSP) to a UE via different network elements and/or distribution techniques. In one example, a method may include obtaining, by a network element, a policy object from a policy function of a mobile network operated by a mobile network operator, wherein the policy object comprises an application specific user equipment route selection policy (URSP) for an application in which the application specific URSP is encrypted by the policy function; and providing, by the network element, the policy object to a user equipment that has at least one session established with the mobile network, wherein the user equipment is to decrypt the application specific URSP to facilitate network communications for the application via the user equipment.

Abstract: Presented herein are techniques to facilitate dual-connectivity support for a user equipment (UE) in a hybrid cell virtualized Radio Access Network (vRAN) architecture. In one example, a method may include obtaining, by a node of a mobile network via a first cell of a RAN, a request for a UE to connect to the mobile network via the first cell in which the RAN includes at least one shared cell and at least one unique cell; determining that the UE is allowed for dual-connectivity operation; and providing a policy to the UE, wherein the policy identifies, for each of one or more applications, one of a shared cell operating mode or a unique cell operating mode that the UE is to utilize for each of the one or more applications.

Abstract: Multiple authenticated identities for a single wireless association may be provided. First, an Access Point (AP) may provide an association with a client device. The AP may then establish, on the association, a first authenticated session for the client device based on a first media access control (MAC) address and a first identity. Next, the AP may establish, on same the association, a second authenticated session for the client device based on a second MAC address and a second identity.

Abstract: Techniques are described to provide open access in a neutral host environment. In one example, a method includes obtaining, by a mobility management node of a neutral host network, a network connectivity request from a user equipment, wherein the network connectivity request comprises an indication of a preferred service provider to which the user equipment is to be connected; determining, by the mobility management node, that the preferred service provider provides non-subscription-based network connectivity for the neutral host network; based on determining that the preferred service provider provides non-subscription-based network connectivity for the neutral host network, establishing secure communications for the user equipment, wherein the secure communications are established for the user equipment without authenticating an identity of user equipment; and providing network connectivity between the user equipment and the preferred service provider upon establishing the secure communications.
