Method for obtaining interface information of neighbor evolved NodeB/relay node, and wireless relay system

摘要

A method for obtaining interface information of a neighbor Evolved NodeB (eNB)/Relay Node (RN) is provided by the present invention. A Donor Evolved NodeB (DeNB) can establish a corresponding relationship between an eNB identifier of the neighbor eNB/RN network element and the GU Group Id List of the neighbor eNB/RN network element according to X2 interface information, and send the corresponding relationship to the RN network element/neighbor eNB; the DeNB can also send a GU Group Id List and cell information of the neighbor eNB/RN network element to the RN network element/neighbor eNB which can establish the corresponding relationship between the GU Group Id List and the eNB identifier of the neighbor eNB/RN network element. A wireless relay system is also provided by the present invention. The problem that the RN or the eNB network element in a wireless relay system can not obtain the corresponding relationship between the eNB identifier and the neighbor GU Group Id List, caused by the existence of an intermediate network element DeNB, is solved by the present invention.

1. A method for obtaining interface information of a neighbor evolved NodeB (eNB) or a neighbor Relay Node (RN), comprising:
a Donor-eNB (DeNB) receiving an eNB identifier of a neighbor eNB or a neighbor RN network element through one of the following manners: active obtaining, passive receiving or network management configuration; the Donor-eNB (DeNB) establishing a corresponding relationship between the eNB identifier of the neighbor eNB and a core network pool globally unique group identifier list (GU Group Id List) of the neighbor eNB, and sending the corresponding relationship to a neighbor RN network element; or the DeNB sending the GU Group Id List and cell information of the neighbor eNB to the neighbor RN network element, and the neighbor RN network element establishing the corresponding relationship between the eNB identifier of the neighbor eNB and the GU Group Id List of the neighbor eNB; or the DeNB establishing a corresponding relationship between the eNB identifier of the neighbor RN network element and a GU Group Id List of the neighbor RN network element, and sending the corresponding relationship to the neighbor eNB; or the DeNB sending the GU Group Id List and cell information of the neighbor RN network element to the neighbor eNB, and the neighbor eNB establishing the corresponding relationship between the eNB identifier of the neighbor RN network element and the GU Group Id List of the neighbor RN network element; wherein the GU Group Id List indicates a pool of the core network that the eNB belongs to, and is adopted for the neighbor eNB or the neighbor RN network element to judge whether a handover is performed through a S1 interface or a X2 interface.
