  • Patent number: 11962488
    Abstract: Supporting Multipath Transmission Control Protocol (MPTCP) subflows using multipath links, and more specifically supporting MPTCP subflows using Wi-Fi Multi-Link Operation (MLO) or cellular multi-link support may be provided. A multipath link may be established between an Access Point (AP) and a station (STA). The STA may mark the multipath link as Multipath Transmission Control Protocol (MPTCP) capable. Next, a request for an addition of a MPTCP subflow may be received. In response to receiving the request, the MPTCP subflow may be bound to the multipath link, and data from the MPTCP subflow may be sent over the multipath link.

  • Patent number: 11950218
    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.

  • Patent number: 11943619
    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: 20240098477
    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.

  • Publication number: 20230388288
    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.

  • Patent number: 11832124
    Abstract: A method of controlling performance of a wireless device is performed by a node that is in electronic communication with a cellular network. The node includes a processor, a non-transitory memory, and a network interface. The method includes receiving a performance value characterizing a performance of a communication channel between a wireless device and a wireless access point. In some implementations, the wireless device and the cellular network are associated with different radio access technologies (RATs). The method includes determining whether the performance value breaches a performance criterion for the wireless device. The method includes adjusting a first amount of data transmitted to the wireless device from a base station of the cellular network and a second amount of data transmitted to the wireless device from the wireless access point. In some implementations, the combined first and second amounts of data satisfy the performance criterion for the wireless device.

  • Publication number: 20230362675
    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.

  • Publication number: 20230300680
    Abstract: Techniques for dynamically negotiating a service legal agreement (SLA) between a roaming device and a visited network (VN) in an identity federation. An identity profile provided to a user device by an identity provider (IDP) is accessed by the user device. The identity profile includes a first SLA criteria. An advertisement from the VN indicating one or more SLAs supported by the VN is received at the user device. The advertisement is received before the user device has associated with the VN. The IDP and the VN are part of a same identity federation. It is determined that the SLA supported by the VN satisfies the first SLA criteria. Upon that determination, an acceptance is transmitted by the user device to the VN, and the user device is associated with the VN.
