Problems solved by technology

[0005] At the edge of the adjacent network, if the networks of different operators use the same technical standard and the same frequency, after ANR detects the ECGI / CGI and PCI of the target cell, it does not detect the legitimacy of the target cell, but directly transfers the target cell Added to NRT, but the cell actually belongs to another operator, taking this cell as the target cell of handover will eventually lead to the failure of terminal handover

Abstract

The invention discloses a neighbor relation configuration method and system in a mobile network, and an eNodeB. The method comprises giving a response to a measurement report sent from a terminal, and determining a target cell which is to be added in an NRT (neighbor relation table) according to the measurement report; sending a measurement request for the target cell to the terminal; receiving the measurement result for the target cell of the terminal; determining whether the target cell belongs to the network where the terminal exists according to a measured evolved UMTS (Universal Mobile Telecommunications System) land wireless access network cell global identifier for the target cell; and if so, adding a physical cell identifier (PCI) of the target cell in the NRT so as to establish an X2 link between a NodeB of the cell where the terminal exists and a NodeB of the target cell according to the requirements. The neighbor relation configuration method and system in a mobile network can improve the network quality.

Description

technical field [0001] The present invention relates to Long Term Evolution (Long Term Evolution, LTE) technology, in particular, to a method, system and evolved base station for configuring neighbor relationship in a mobile network. Background technique [0002] In adjacent countries or regions, multiple operators may use the same frequency, which causes interference between adjacent networks at the edge of the network due to the same frequency. [0003] When the network uses Automatic Neighbor Relation (ANR), the ANR function resides in the evolved base station (eNodeB, eNB) and is responsible for managing the Neighbor Relation Table (NRT). Its neighbor detection function is responsible for discovering the E-UTRANCellGlobalIdentifier (ECGI) / CellGlobalIdentifier (CGI) and physical cell identity of the target cell in the Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (PhysicalCellIdentifier, PCI), and add PCI to NRT. [0004] In ...
