Title:
AUTOMATIC NEIGHBOR RELATION (ANR) FUNCTIONS FOR RELAY NODES, HOME BASE STATIONS, AND RELATED ENTITIES
Document Type and Number:
WIPO Patent Application WO/2011/163403
Kind Code:
A3
Abstract:
Certain aspects of the present disclosure provide methods and apparatus for implementing Automatic Neighbor Relation (ANR) functions for relay nodes (RNs), home base stations (e.g., home evolved Node Bs (HeNBs), and related entities (e.g., donor evolved Node Bs (DeNBs) and HeNB gateways). X2 is designed to be an end-to-end protocol between two evolved Node Bs (eNBs). However, for the case of RNs or HeNBs, this protocol may involve a proxy function (e.g., where the DeNB acts a proxy for the RN). This creates several issues, such as how to manage a potentially very large set of cells under a gateway and how to route S1 messages used for X2 endpoint discovery. Therefore, certain aspects of the present disclosure generally relate to methods and apparatus for maintaining the X2 connections intelligently and hiding the large number of nodes from the X2 endpoints based on various triggers.
