Abstract: In one aspect, a method of IP obfuscation of a user device includes receiving, over an Extendible Authentication Protocol (EAP) session between a user device and a network access point, location preferences of the user device, generating, based on the location preferences or a network policy, a geohash for the user device, identifying, for the user device, an IP anchor, sending, over the EAP session, the geohash to the user device, and receiving, from the user device, network traffic, wherein the network access point utilizes the geohash and the IP anchor to route the network traffic for the user device and obfuscate IP address of the user device from third-party access.

Abstract: The present disclosure is directed to migrating network traffic from a licensed spectrum to an unlicensed spectrum within the same radio access technology (RAT). In one aspect, a method includes identifying a user device connected to a cellular wireless access technology, over a licensed spectrum; determining whether a condition for switching network traffic associated with the user device to an unlicensed spectrum is triggered; in response to determining that the condition is triggered, determining an unlicensed spectrum to move the network traffic to, the unlicensed spectrum being within a same cell as the licensed spectrum or in a different cell compared to a cell in which the licensed spectrum is; and migrating at least a portion of the network traffic to the unlicensed spectrum while maintaining network connectivity of the user device over the cellular wireless access technology.

Abstract: The present disclosure relates to simultaneous operation of Wi-Fi access points in a super cell mode and a standalone mode and controlling connectivity of end terminals thereto. In one aspect, a method includes receiving a configuration for a group of access points operating within a network, the configuration allowing each access point of the group to operate in a super cell mode over a shared frequency channel and a standalone mode over a non-shared frequency channel. The method further includes determining, for an end terminal, whether the end terminal is to connect to the network over the shared frequency channel or the non-shared frequency channel based on a network policy to yield a determination; and controlling connectivity of the end terminal to at least one access point of the group of access points over the shared frequency channel or the non-shared frequency channel based on the determination.

Abstract: The present technology is generally directed to dynamically adding network resources based on an application function (AF) notification. The present technology can determine, by an AF of a service provider, a network congestion on a network, the network congestion indicating that network resources for servicing a user device using services of the service provider do not meet corresponding Quality of Service (QoS) requirements. Further, the present technology can transmit a notification by the AF to a core network of a network provider to request additional network resources to be allocated for servicing the user device, the network provider providing network connectivity for the user device to receive the services provided by the service provider.

Abstract: Systems, methods, and computer-readable media are provided for inter-network messaging among private and public 5G networks. For instance, a first server on a public 5G mobile network can receive a first message directed to a first wireless device associated with a first network identity. The first server can determine, based on the first network identity, that the first wireless device is associated with a second network identity, wherein the second network identity is used to identify the first wireless device on a private 5G mobile network. The first server can send a copy of the first message to a second server on the private 5G mobile network for transmission to the first wireless device through the private 5G mobile network based on the second network identity.

Abstract: Systems and methods are provide to bring network capability awareness to steering of roaming (SoR). A home network includes a capabilities list of visited networks and their associated with the network capabilities. For SoR, he user equipment (UE) maintains a roaming partners list (RPL). The RPL provides a list of visited networks arranged in order of priority/preference (e.g., the first visited network in the RPL has first priority). The first visited network receives a registration request from the UE and relays a corresponding authentication request to the home network. The visited network in the RPL can be reordered when the UE requires a network capability not supported by the first visited network in the RPL, as indicated by the capabilities list. Depending on the implementation, the UE or the home network can make this decision to reorder the RPL.

Abstract: The present disclosure is directed to a comprehensive Route Selection Policy (URSP) based on Wi-Fi multi-link operation. In one aspect, a method includes identifying a user device connected to an enterprise network that provides network connectivity to user devices over multiple radio access technologies; receiving network capability information indicating that the user device is capable of a multi-link operation over a Wi-Fi network, the Wi-Fi network being one of the multiple radio access technologies; determining a URSP for the user device, wherein the URSP is a singular route selection policy for the user device to send and receive data over the multiple radio access technologies and defines, in part, a per-application traffic routing rule for routing a portion of traffic for an application used on the user device, over one of multiple links available on the Wi-Fi network; and transmitting the URSP to the user device.

Abstract: Systems, methods, and computer-readable media are provided for on-boarding network devices onto a private 5G network. An example method can include discovering a first private 5G network upon the network device being turned on, authenticating, at the network device, the network device, downloading a second network profile from an SM-DP+ server of a second private 5G network, and on-boarding the network device to the second private 5G network.

Abstract: Network energy efficiency and green power selection may be optimized by employing graph-oriented service chains configured to share sustainability attributes and metadata augmentation. More specifically, network Service Function Chain (SFC) creation can include a set of power and energy-specific and sustainable attributes. In general, the goal of SFC is to enable the creation of a service path that matches the specific needs of an application or service. SFCs are composed of a sequence of network functions, such as firewalls, load balancers, intrusion detection systems, and other services. Each network function performs a specific task on the network traffic, and the packets are passed from one function to the next until they reach their destination. Overall, SFCs are a powerful tool for managing complex network environments, enabling network administrators to deploy and manage network services more efficiently and effectively.
