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 are described to provide multipath mobility via Domain Name System-as-an-Authoritative Source (DNS-AS) techniques. In one example, a method includes obtaining, by a multipath policy decision element, a plurality of multipath policy recommendations for an application, wherein the plurality of multipath policy recommendations are obtained from one or more multipath policy recommendation elements; combining the plurality of multipath policy recommendations to generate a policy enforcement decision, wherein the policy enforcement decision identifies, at least in part, one or more network paths that are to be utilized for one or more packet flows associated with the application, wherein each of the one or more network paths is associated with an access type; and enforcing the policy enforcement decision for one or more packet flows associated with the application.

Abstract: Presented herein are techniques to facilitate wireless authorization based on in-line assurance and tariffing information. In one example, a method may include obtaining, by a home network, a request to authorize access of a roaming subscriber for a visited network; determining whether the request includes visited network charging information and visited network metric information; based on determining that the request includes the visited network charging information and the visited network metric information, determining whether one or more visited network metrics satisfy one or more threshold metrics for the roaming subscriber; and based on determining that the one or more visited network metrics satisfy the one or more threshold metrics for the roaming subscriber, authorizing access of the roaming subscriber for the visited network.

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.

Abstract: Techniques are provided for downlink packet replication to support handovers. In one example, downlink packet replication occurs on a fabric node in an S1AP handover scenario. In another example, downlink packet replication occurs on a source Access Point (AP) using a target AP as a secondary AP in an S1AP handover scenario. In yet another example, downlink packet replication occurs on a source AP using packet encapsulation in an S1AP handover scenario. In still another example, downlink packet replication occurs on a source AP in an X2 handover scenario. Similar techniques are provided for any suitable telecommunications/cellular technology.

Abstract: Techniques are described to provide for the ability to combine policies in a manner that utilized policy purposes to generate a combined policy. In one example, a method includes obtaining, at a network entity of a network, a plurality of policies, wherein each policy is associated with a policy purpose defined by a policy originator; combining the plurality of policies by the network entity to generate a combined policy, wherein the combining is performed based on a ranking of policy purposes; and enforcing the combined policy at one or more policy enforcement entities of the network for one or more packet flows communicated between a client and the network.

Abstract: Techniques are described to provide traffic steering and policy combining in a mobile network. In one example, a method includes combining, by a policy function of a network, a user equipment (UE) access policy comprising UE access rules obtained from a UE with a network-based access policy associated with the network to generate a combined access policy, the combined access policy comprising combined access rules; communicating the combined access rules to the UE via a message, wherein the message comprises an indication that indicates that the UE is not allowed to override the combined access rules with the UE access rules; and communicating the combined access rules to a user plane function handling traffic for the UE.

Abstract: Systems, methods, and computer-readable media for radio resource management in a Citizens Broadband Radio Service (CBRS) network include one or more CBRS devices (CBSDs) which can obtain a group type associated with the CBSDs and their associated Radio Environment Map (REM) reports of one or more frequency channels of the CBRS network. The group type and the REM reports may be provided to a Self-Organizing Network (SON) manager of the CBRS network, where the SON manager may determine and provide to the CBSDs, one or more of a channel utilization information, transmission power, or mobility load management information for the CBSD, based on the group type and the REM reports.

Abstract: A method includes transmitting a message to a first end point that includes an instruction to initiate a communication type in which the communication type includes sharing a randomization token between the first and a second end point. The method further includes obtaining a first communication report from the first end point and a second communication report from the second end point in response to initialization of a communication based on the communication type in which the first and second communication reports respectively include a first and second hash that corresponds to a function of the randomization token and identity information. The method further includes determining whether the first hash matches the second hash and generating a value that correlates the first and second end points with the communication across the network in response to determining that the first hash matches the second hash.
