Problems solved by technology

[0003] Although a given eNB may only have 20-30 neighbor eNBs at a given time, the challenge is to dynamically create paths on a Hierarchical Multiprotocol Label Switching (H-MPLS) network only to eNBs with X2 relationships

Abstract

In one embodiment, a method for automatically creating a network route using a discovered IP address includes a first network device creating a connection-oriented interface with a first radio base station (RBS) for exchanging packets originating from the first RBS destined for the first network device, and for exchanging packets originating from the first network device destined for the first RBS, by receiving a first HELLO packet originating from the first RBS destined for the first network device, and transmitting a first HELLO packet destined for the first RBS. The method includes receiving, via the connection-oriented interface, a first CONNECT packet from the first RBS, the first CONNECT packet including a first IP address of the second RBS. The method includes creating a first network route between the first RBS and the second RBS using the first IP address included in the first CONNECT packet.

Description

technical field [0001] Embodiments of the present invention relate to the field of packet networks; more specifically, to network topology discovery and automatic creation of network routes. Background technique [0002] Currently, most X2-handover communications in Long Term Evolution (LTE) networks are switched centrally at local / regional switching sites. However, the 3rd Generation Partnership Project (3GPP) is working to define new applications that will be carried over the X2 interface, the interface used by eNodeBs (eNBs) to communicate with each other in an LTE network. These new applications include, for example, Coordinated Multipoint (CoMP), Enhanced Inter-Cell Interference Cancellation (eICIC), Location Services, and more. These applications require much higher bandwidth while being much less latency tolerant. Therefore, there is a need to efficiently route X2 traffic at the point closest to the eNB. [0003] Although a given eNB may only have 20-30 neighbor eN...
