Abstract: Embodiments herein describe techniques for mapping cellular slices to a Wi-Fi Network. It may be advantageous to port the slice constructs from a cellular network (e.g., 5G) to the Wi-Fi system. In one embodiment, templates are established for each slice which define different parameters that are used when the slice is implemented on a cellular network and a Wi-Fi network. A service provider can establish a template for each slice. In one embodiment, the template includes parameters for each slice for both cellular and Wi-Fi networks.

Abstract: Techniques for performing optimized handovers of a client device between access points in wireless networks are provided. A first access point exchanges packets with a client device. The first access point receives a disassociation notice from the client device. In response to the disassociation notice, the first access point buffers one or more packets received for the client device in a first buffer. The first access point receives an indication from a controller to transmit the one or more packets in the first buffer to a second access point. In response to the indication, the first access point transmits the one or more packets in the first buffer to the second access point.

Abstract: Service chain integration with a Wireless Local Area Network (WLAN) may be provided. A computing device may send metadata from a wireless network to a Service Function (SF) selected from one of a plurality of SFs. Then the computing device may receive a control trigger from the SF in response to the metadata. The computing device may then perform a service action on the wireless network in response to the control trigger.

Abstract: Techniques for network communications are disclosed. These techniques include receiving a cryptographically generated device identifier (CGDI) and a public key relating to a wireless station (STA). The techniques further include determining a first hash based on decrypting the CGDI using the public key, and validating the first hash for an access network. The techniques further include identifying the STA in the access network using the CGDI based on binding the CGDI to a session associated with the STA and the access network.

Abstract: In one embodiment, a method is performed. A device may receive a registration request from a user equipment (UE) device associated with a category. The device may receive a registration response from an access and mobility function (AMF). The registration response may comprise a group identifier associated with the category. The device may select resources from a resource pool based on the group identifier. The resource pool may be dedicated for use for emergency communications. The device may allocate the selected resources to the UE device.

Abstract: Techniques for wireless communications are disclosed. The techniques include generating a provisioning domain (PVD) identifier by associating a roaming consortium organization identifier (RCOI), relating to an identity federation comprising an identity provider (IDP), with the PVD. The techniques further include providing PVD configuration information from the IDP to a wireless station (STA) associated with the IDP, using the PVD identifier. The techniques further include applying one or more configuration policies at the STA based on the PVD configuration information.

Abstract: Dynamic policy mapping is provided via mapping, by an Access Point (AP), a plurality of applications to a set of privilege groups for Quality of Service (QoS) levels in a network; transmitting the mapping of the privilege groups to a client device; receiving packets from the client device including QoS markers; and in response to determining that the QoS markers received from the client device do not match the privilege groups for the packets, performing a corrective action on the client device, wherein the corrective action includes one or more of: disassociating the client device from the network; and retransmitting the set of privilege groups to the client device. In some embodiments, the privilege groups are transmitted before the client device is associated with the AP, enabling the client device to select what AP to associate with based on the privilege groups.

Abstract: In one embodiment, a system, apparatus, and method are described for requesting access authorization from an access network access point (AP) via an access network interface, generating at a processor a public-private key pair to be used to generate a cryptographically generated address (CGA) upon receiving the access authorization, sending a secure neighbor discovery (SeND)—neighbor solicitation (NS) to the AP via the access network interface after the public-private key pair has been generated, receiving a signed user location information (ULI) from the AP in response to the SeND-NS, and sending the signed ULI to one of a 3GPP mobility controller or an emergency service via a 3GPP network interface. Related systems, apparatuses, and methods are also described.

Abstract: Embodiments are directed to a virtual mobility anchor network element to receive, from a packet gateway (PGW) node, a request for an internet protocol (IP) address for a mobile device, establish an IP address for the mobile device; and provide the IP address to the PGW node in response to the request for the IP address for the mobile device. The virtual mobility anchor network element is configured to receive IP traffic from a network location; determine a target destination for the IP traffic based on a destination IP address, the destination IP address comprising the second IP address; and forward the IP traffic to the PGW node associated with the destination IP address. The virtual mobility anchor network element is also configured to receive IP traffic from the PGW node; determine a target destination for the IP traffic; and route the IP traffic to the target destination.
