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: 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: In one example, a control plane entity obtains an indication that a User Equipment (UE) has entered an idle mode. The control plane entity sets a routing locator corresponding to the UE to cause the control plane entity to trigger a paging request toward the UE to prompt the UE to transition from the idle mode when a first network node obtains a downlink packet destined for the UE. The control plane entity obtains a notification that the first network node has obtained the downlink packet and initiates the paging request toward the UE. The control plane entity updates the routing locator corresponding to the UE to cause the first network node to transmit further downlink packets destined for the UE toward a second network node configured to handle traffic on behalf of the UE.

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.
