Abstract: Techniques to adaptively support/enable a wireless network feature for certain wireless client devices without hampering the performance or connectivity of wireless client devices which do not support that wireless network feature. An access point or wireless network controller adaptively enables a wireless network feature without advertising support for the wireless network feature in a wireless network-standard compliant manner to allow one or more wireless clients that support the wireless network feature to use the wireless network feature when associated to the access point while enabling association of one or more wireless clients that do not support the wireless network feature.

Abstract: Methods are provided for extending sponsored Wi-Fi guest access capability to other enterprise tools and/or access technologies such as private access networks including private LTE and 5G networks. The methods include a controller detecting a user equipment (UE) that is connected to a guest access service provided by a wireless local access network (WLAN) and generating a profile for the guest access service. The methods further include the controller providing, to the UE, the profile to cause the UE to connect to the guest access service provided by another access network.

Abstract: Embodiments identify a station that rotates an over the air station address. As address rotation was not originally designed into wireless networks, the rotation can introduce communication challenges for the station. The embodiments derive that traffic referencing two different over the air station addresses are associated with a single common station. This is accomplished by determining a similarity between properties of two sets of traffic. A first set of traffic references the first over the air station address and a second set of traffic references the second over the air station address. If the properties common across the two sets of traffic indicate sufficient similarity, the embodiments determine that both sets of traffic are associated with a single device. Network configuration of the device is then adjusted based on the determination.

Abstract: In one example, a Network Policy Function (NPF) obtains a first identifier for a User Equipment (UE) based on communications between the UE and a first access network of a system, and an Internet Protocol (IP) address used by the UE to communicate over the first access network. The NPF obtains a second identifier for the UE based on communications between the UE and a second access network of the system. The NPF determines that the UE used the IP address to communicate over the first access network of the system based on a correlation between the first identifier for the UE and the second identifier for the UE. The NPF provides the IP address to the UE, and the UE uses the IP address to communicate over the second access network.

Abstract: In one embodiment, a client device having a plurality of radios obtains a list of basic service set identifiers (BSSIDs) for a plurality of wireless access points of a wireless network. The client device associates each of the plurality of radios of the client device with a different wireless access point of the wireless network, based on the obtained list of BSSIDs. The client device receives a copy of a data packet from a particular one of the associated wireless access points. Each of the associated wireless access points receives a replicated copy of the data packet to be transmitted towards the client device. The device causes the associated wireless access points to cease further transmission of their copies of the data packet by acknowledging receipt of the data packet to the particular wireless access point.

Abstract: An Evolved Node B (eNB) provides an internet indication to a User Equipment (UE) to enable the UE to quickly obtain internet access. The eNB determines that the eNB is connected to at least one gateway that provides public internet access, and broadcasts an internet indication in a predetermined System Information Block (SIB). The eNB receives an attach request from the UE including an attach type of internet enabled and a Packet Data Network (PDN) type of internet enabled. The eNB forwards the attach request to a Mobility Management Entity (MME).

Abstract: In one example, a server obtains, from a device having an embedded Subscriber Identification Module (eSIM), a unique identifier of the eSIM. The server validates the device based on the unique identifier of the eSIM. The server provides, to the device, a unique credential for a profile of the eSIM. The profile of the eSIM corresponds to a network of an enterprise. The server provides, to a credential database, the unique credential for the profile of the eSIM. The credential database including the unique credential for the profile of the eSIM indicates that the device is permitted to access the network of the enterprise.

Abstract: Stateful roaming techniques are provided for use in a wireless network. In one embodiment, a method is provided that includes: obtaining flow information descriptive of one or more traffic flows associated with a wireless client device that is associated to a current access point in a wireless network; storing state data representing the flow information for flows associated with the wireless client device together with a traffic descriptor for each flow; determining that the wireless client device is seeking to roam from the current access point to a new access point; and sending the state data for the wireless client device to the new access point to enable the new access point to apply a policy based on the state data before the wireless client device completes its roam to the new access point.
