Embodiment Construction

[0032]Technology trends including network functions virtualization and software-defined networking (SDN) provide means for scaling, managing, and operating highly distributed networks whose control functions cannot exist on dedicated node-based or in the method of a dedicated server. Virtualization of the EPC functions and the network makes it possible to obtain a controller with a view of the transport resources available for the PDN connection. With the development of carrier-grade Ethernet based on Transport Interconnection of Lots of Links (TRILL) and Shortest Path Bridging (SPB) routing instead of Spanning Tree Protocol (Spanning Tree Protocol, STP), short convergence times and good network utilization can be established robust Ethernet backhaul network. The advantage of virtualizing the PDN connection with a controller located at the EPC site, such as a (centralized) switch controller coupled to the EPC controller or the EPC controller itself (including the switch contr...

Abstract

A method, apparatus and system related to a packet data network (PDN) connection for a radio access network (RAN) (38) are provided. The PDN connections between eNB (36) of the RAN and an Evolved Packet Core (EPC) are forward though Ethernet switching network (34). A controller at Evolved Packet Core (EPC) site (30) such as EPC controller or centralized switch controller (32) is configured to configure flow table entries along the transport path from eNB to a gateway (14) of the EPC.

Description

technical field [0001] The present disclosure relates generally to packet data network connections, and more particularly to methods, apparatus and systems for implementing PDN connections. Background technique [0002] Wireless devices are becoming more and more diverse, with not only hundreds of millions of phones, but potentially an even greater number of sensors, machines that facilitate machine-to-machine communication and everything in the so-called Internet of Things (IoT) entity. The number of these devices is expected to increase by several orders of magnitude by 2020, so dense wireless networks are likely to emerge. Both data and signaling for mobile devices are expected to grow exponentially over the next 5 years or more. However, localized data traffic patterns may dominate. A centralized architecture using a centralized core network to serve all wireless nodes in mobile networks such as Third Generation Partnership Project (Third Generation Partnership Projec...
