  • Patent number: 12641408
    Abstract: Roaming validation for Access Network Providers (ANPs), and particularly to protecting communications between Stations (STAs) and ANPs while providing roaming validation for ANPs may be provided. An ANP may first register a roaming federation system. The ANP may determine a roaming message based on subscription features of the network, and the ANP may request signing of the roaming message by the roaming federation system. The ANP may receive the signed roaming message from the roaming federation system and send the signed roaming message to a STA. The ANP may then receive a request to connect to the network from the STA and initiate a connection for the STA.

  • Patent number: 12621719
    Abstract: Provided herein are techniques to facilitate conflict management in a shared Open Radio Access Network (O-RAN) architecture. In one instance, a method can be performed by a conflict manager of a near-real-time RAN intelligent controller of a shared RAN including radio unit (RU) nodes provided by a host operator. The method can include obtaining each of a requested radio unit (RU) configuration from each of a distributed unit (DU) node operated by each of a tenant operator and determining whether there are any conflicts among RU configuration parameters for each requested RU configuration. In one instance, upon determining one or more conflicts among the RU configuration parameters for each requested RU configuration, the method may include providing a response to each DU node indicating that each DU node is allowed to configure the plurality of RU nodes using each requested RU configuration in accordance with a modification.

  • Patent number: 12500943
    Abstract: Differentiated service in a federation-based access network is provided by receiving a set of credentials from a User Equipment (UE) for a wireless network offering a plurality of service levels. In response to determining that the set of credentials indicate a realm associated with a given service level, network access is provided to the UE according to the given service level. In response to determining that the given service level is not a highest service level in the wireless network, a list of one or more preferred realms is transmitted to the UE, where each realm of the list of one or more preferred realms is associated with one or more higher service levels than the given service level.

  • Publication number: 20250380337
    Abstract: A method for exposing a location associated with an emergency call may include receiving, at a first network, a request to initiate an emergency session from a user device associated with a second network. The request may trigger the first network to determine location information of the user device. Data associated with the location information of the user device is maintained by the second network in one or more databases. The method may further include querying, by the first network, the DNS for the location information associated with the user device. The one or more databases may be updated by the second network. The method may further include receiving, at the first network and from the DNS via the one or more databases, the location information associated with the user device. The method may further include updating the emergency session based on the location information.

  • Publication number: 20250294357
    Abstract: The presently claimed disclosure is directed to methods that may be implemented at a computer. Methods and systems consistent with the present disclosure may include extending protocols associated with authenticating client (i.e. supplicant) devices and with authorizing those supplicant devices to access a wireless network. These methods may include sending data relating to the failure of an authentication and/or an authorization process to a supplicant device attempting to access a wireless network. Methods discussed within may include securely sending failure codes or reasons to a supplicant device that identify why an authentication or authorization process failed. These methods may include sending messages between a supplicant device, an authenticator device, and an authentication and authorization server. After a first failure, the supplicant device may be able to access the wireless network after a reason or code of that failure has been reported to the supplicant device.

  • Publication number: 20250168633
    Abstract: Techniques for enhancing the security of network access within an open roaming framework are provided. A first network device receives a request to authenticate connection of a user device to a network. The first network device retrieves security data associated with the network. Based on analyzing the security data associated with the network, the first network device determines that one or more security criteria are satisfied. The first network device transmits a response to the user device, where the response instructs the user device to establish a connection with the network and does not disclose the security data.

  • Publication number: 20250097209
    Abstract: The disclosed technology relates to a process of evaluating any number of different identity providers (IDPs) and their respective set of credentials that are used to authenticate corresponding users to assist with the onboarding of the different IDPs in connection with Wi-Fi identity federations. In particular, the process allows a person's electronic identity and attributes (stored across one or more IDPs) to be determined once using a standard. Once trust has been established for the user, that trust can then be utilized across a number of different systems (e.g., Single-sign on). The same trust determination can be used without the need for the authenticity of the user identity to be re-evaluated with each new access request.
