Abstract: Technologies for systems, methods and computer-readable storage media for solving complex distributed congestion in a 5G network by using traffic engineering data to redirect sessions. Specifically, involving anchoring a network node to a User Plane (UP) entity based on traffic engineering data and subscribing to traffic engineering data associated with requested parameters to push particular policies and/or select alternate application functions to correct congestion.

Abstract: In one embodiment, a method is performed. A first user plane entity may be associated with a user plane group comprising a plurality of user plane entities. The first user plane entity may be associated with a second user plane entity. A failure of the second user plane entity may be detected. In response to detecting the failure of the second user plane entity, the first user plane entity may be activated.

Abstract: Presented herein are embodiments that provide mobile edge computing (MEC) with low latency traffic segregation within a packet data network (PDN) using dedicated bearers. Techniques are provided that are performed at an edge user plane entity and a control plane entity to coordinate the directing of low latency traffic over a dedicated bearer broken out at the edge, and to communicate normal latency traffic over a default bearer that is centrally broken out.

Abstract: An example method is provided in one example embodiment and may include receiving an indication of a radio access technology (RAT) change for a user equipment (UE); determining availability of a preferred RAT type for a policy related rule associated with the UE, wherein the policy related rule includes, at least in part, the preferred RAT type for one or more service data flows for the UE; and configuring the one or more service data flows for the UE based, at least in part, on a change in availability of the preferred RAT type following the RAT change. In at least one case, the method can include routing downlink packets to the UE using the one or more service data flows for the preferred RAT type if the preferred RAT type is available.
