Abstract: Techniques for trusted roaming between identity federation based networks. A first wireless access point (AP) receives a roaming request from a wireless station (STA), to roam from the first AP to a second AP. The first AP is associated with a first access network provider (ANP), the second AP is associated with a second ANP, and the first ANP is different from the second ANP. Authentication information relating to the STA is transmitted from the first ANP to the second ANP using a trusted connection. The trusted connection was previously established between the first ANP and the second ANP based on a query to an identity federation to which both the first and second ANP belong. The STA is de-associated from the first AP. The STA is re-associated at the second AP using the transmitted authentication information.

Abstract: Automatic onboarding of a device onto a cellular network may be provided through a Wireless Local Area Network (WLAN). Subsequent to a device connecting to a first network (e.g., the WLAN), information associated with the device and the first network may be received. One or more tags may be generated and an intent profile may be defined for the device based on the received information, where the intent profile may indicate at least a second network (e.g., the cellular network) that the device is enabled to connect with and one or more policies associated with the connection. The tags and intent profile may be transmitted to a service provider platform, and an onboarding profile template identified using the tags and the intent profile may be received from the service provider platform. The onboarding profile template may be provided to the device to enable connection to the second network.

Abstract: Various embodiments herein disclose coordinating neighbor discovery between access points (APs) with auxiliary radios and APs without auxiliary radios. A corresponding wireless controller comprises a processor and a memory storing instructions that, when executed, cause the controller to perform operations. The operations comprise grouping APs into a first group of more flexible APs and a second group of less flexible APs and querying the second group of APs for a corresponding broadcast interval. The operations further comprise identifying when the second group of APs is scheduled to broadcast parameters, and a broadcast interval for each of the second group of APs and generating a schedule based on the scheduled broadcast and the broadcast interval for each of the second group of APs. The operations additionally comprise providing the generated schedule to the first group of APs and the second group of APs.

Abstract: Federation policy exchange is provided in response to receiving a sharing query from an Access Point (AP) indicating that an associated wireless network supports federated identities with data sharing, determining whether the sharing query is within sharing preferences; and in response to determining that the sharing query is within the sharing preferences, transmitting, to the AP, a positive response for identity sharing that authorizes collection and sharing of identity data with at least one entity identified in a sharing policy for the associated wireless network. In various embodiments, federation policy exchange includes transmitting a support notification, via an AP, indicating support for federated identities with data sharing within a wireless network associated with the AP; and in response to receiving a first identify sharing preference from a User Equipment (UE) that indicates that negotiation is preferred, transmitting a sharing policy for the wireless network to the UE.

Abstract: Channel availability check optimization may be provided. A plurality of Pulse Repetition Intervals (PRIs) may be determined for a respective plurality of bursts on a respective plurality of frequencies. A list of at least a portion of the plurality of frequencies may be generated. The list may include a plurality of bias factors respectively indicating a probability that each of the respective plurality of bursts was a radar burst based on the respective plurality of PRIs. An Access Point (AP) may perform a plurality of preemptive Channel Availability Checks (CACs) on each of the respective plurality of frequencies on the list in order of highest probability to lowest probability based on the plurality of bias factors.

Abstract: Device-to-Device (D2D) communications in hybrid networks are provided by identifying a first dual-mode endpoint seeking to communicate with a second dual-mode endpoint via a D2D communications session; identifying a first communications pattern of network resource usage for the first Radio Access Technology (RAT) and a second communications pattern of network resource usage for the second RAT in the heterogeneous wireless network environment; assigning the D2D communications session to the first RAT based on the first communication pattern and the second communication pattern; and in response to detecting network resource usage changes in the first RAT, transitioning the D2D communications session to the second RAT. In some embodiments, the D2D communications session is assigned to the first RAT using a shared frequency regulated by a band access controller that is reserved as a static resource for D2D communication while high-priority signals are absent from the shared frequency.

Abstract: A method includes linking, at an access node, a first media control access (MAC) address of a device to an identifier of the device to establish a communication session between the access node and the device and during the communication session, receiving, at the access node, an indication of a change of the first MAC address to a second MAC address. The method also includes linking, at the access node, the second MAC address to the first MAC address and the identifier and receiving, at the access node, a communication from the device using the second MAC address while maintaining the communication session.

Abstract: Techniques for access point (AP) based location computation are disclosed. A target wireless AP, communicatively coupled to a wireless station (STA), is identified. One or more location buddy APs, relating to the target AP, are identified based on the physical locations of the location buddy APs and the target AP. It is determined that a first location buddy AP, of the one or more location buddy APs, is communicatively coupled to the STA, and in response a location of the STA is determined using the target AP.

Abstract: Techniques for determining a range between a wireless station (STA) and a wireless access point (AP) using channel state information are described. An AP determines channel state information corresponding to an STA. The AP determines, based on the channel state information, one or more fine timing measurement (FTM) parameters. A plurality of FTM messages are transmitted between the AP and the STA, based on the one or more FTM parameters. The STA is configured to determine an estimated range to the AP based on the plurality of FTM messages.
