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: A network function is configured to initiate a bulk session cleanup with a single release request. The network function detects a configuration change to a wireless network system that affects multiple user sessions for multiple user devices. The network function generates a single bulk session release request identifying the affected user sessions and provides the single bulk session release request to at least one other network function responsible for the user sessions.

Abstract: Techniques are described herein for providing radio resource ownership indicators in charging records for a charging function. In one example, a method may include determining, by a session management node of a mobile network, that a user equipment is utilizing a particular radio resource of a mobile network resource for a Protocol Data Unit (PDU) session of the user equipment, wherein the mobile network resource is capable of being utilized via a plurality of radio resources and the particular radio resources is associated with an enterprise entity; and reporting charging information for the PDU session of the user equipment to a charging function of the mobile network to facilitate storing a charging record for the user equipment that is to include an identifier of the enterprise entity that is associated with the particular radio resource.

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 wireless wide area (WWA) virtualized Radio Access Network (vRAN) (e.g., 5G) to wireless local area (WLA) RAN (e.g., Wi-Fi) steering or WLA RAN to WWA vRAN steering for one or more UE. In one example, a method may include obtaining first performance metrics associated with links of a WWA vRAN (e.g., fronthaul, midhaul, and backhaul links); obtaining second performance metrics associated with links WLA RAN (e.g., backhaul links); and in response to determining that one of the WWA vRAN is experiencing degraded performance based on the first performance metrics or the WLA RAN the second performance metrics, activating a steering event that causes, at least in part, an indication to be communicated to a UE to cause the UE to connect to the WWA vRAN or the WLA RAN that is not experiencing degraded performance.

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 for extending a cellular quality of service bearer through an enterprise fabric network. In one example, a method obtaining, by a first switch of a network, a packet to be delivered to a client connected to the network via a cellular access point; identifying quality of service (QoS) bearer information associated with the packet, wherein the QoS bearer information is associated with a radio access bearer for the client and the QoS bearer information comprises a bearer indicator and a QoS class identifier; providing a fabric tunnel encapsulation for the packet, wherein the bearer indicator and the QoS class identifier are included within the fabric tunnel encapsulation of the packet; and forwarding the packet within the fabric tunnel encapsulation toward a second switch of the network via a fabric tunnel, wherein the cellular access point is connected to the network via the second switch.

Abstract: Dynamic roaming partner prioritization based on service quality feedback may be provided. First, a server associated with an enterprise may receive performance data and location data for each of a plurality of service provider networks from a plurality of end use devices associated with the enterprise. Next, the server may assign a ranking to a plurality of service providers by location based upon information. The information may comprise the received performance data and the location data corresponding to each of the plurality of service provider networks. The server may then push the ranking to a first end use device.

Abstract: This disclosure describes techniques for selecting network protocols using heatmaps. For instance, a system may receive radio frequency information from one or more sources located within an environment. The system may then generate heatmaps using the radio frequency information, where the heatmaps represent characteristics associated with different network protocols. The characteristics may include signal strengths, throughputs, data packet drop rates, data packet retry rates, and/or the like for various locations within the environment. A user device may then receive the heatmaps from the system. Using a location of the user device and the heatmaps, the user device may determine to communicate using a network protocol from the different network protocols. The user device may then establish a connection using the network protocol.
