Communication method and device between base stations based on X2 agency

Abstract

The invention discloses a communication method and device between base stations based on an X2 agency. The method and device aim to solve the problem that X2 signals cannot be forwarded accurately due to the fact that the identification information which is distributed for X2 signal information by all family base stations is not unique in an X2 agency module. The method includes the steps that first, when the X2 signal information of the first family base station and the X2 signal information of the second family base station are received, global identification information is distributed, and a first mapping relation is established among the identity of the first family base station, the first identification information distributed by the first family base station and the global identification information; a second mapping relation is established among the identity of the second family base station, the second identification information distributed by the second family base station and the global identification information; when the X2 agency receives the X2 signal interaction between the first family base station and the second family base station again, the X2 signals are accurately forwarded to corresponding target base stations based on the global identification information, the first mapping relation and the second mapping relation, and thus the X2 signals can be accurately forwarded.

Description

technical field [0001] The invention relates to the communication field, in particular to an X2 agent-based communication method and device between base stations. Background technique [0002] Compared with the traditional mobile communication network in the Long Term Evolution (LTE) mobile communication network, a major change is that the evolved base stations (Evolved NodeB) realize interconnection and intercommunication through the X2 interface, forming a so-called mesh network. [0003] In related technologies, a home base station (Home evolved NodeB, HeNB) is a small, low-power base station, and is mainly deployed in indoor places such as homes and offices. The role of the HeNB is to provide users with higher service rates, reduce the cost of using high-rate services, and at the same time make up for the lack of coverage of existing distributed cellular wireless communication systems. HeNB has the advantages of affordability, convenience, low power output, and plug-and...
