Embodiment Construction

[0037] like figure 1 Shown is a flowchart of an embodiment of the method for transmitting interference information between base stations of the present invention, including:

[0038] Step 1. When the X2 interface between the first base station and the second base station fails, the first base station sends interference information to the MME through the S1 interface;

[0039] Step 2. The MME sends the received interference information to the second base station.

[0040] In the 3GPP protocol, S1 is an interface for communication between a base station and an MME, and X2 is an interface for mutual communication between adjacent base stations. In the embodiment of the present invention, when the X2 interface between adjacent base stations fails, the interference information can be transmitted to the adjacent base station through the S1 interface between the base station and the MME, thus solving the problem that occurs when the X1 interface fails. Transmission of interference ...

Abstract

The invention relates to an interfering information inter-base station transmission method and a system, base stations and a mobile management entity; wherein, the method comprises as following: when an X2 interface between a first base station and a second base station turns has faults, the first base station sends interfering information to the mobile management entity through an S1 interface, and the interfering information is used for indicating the information base station, which is interfered; and the mobile management entity can sends out the received the interfering information to the second base station. The embodiment of the invention can transmit the interfering information through the S1 interface when the X2 interface between adjacent base stations has faults, so as to solve the problem of the interfering information transmission between the adjacent base stations.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method and system for transmitting interference information between base stations, a base station and a mobile management entity (Mobile Management Entity, MME for short). Background technique [0002] After the Long Time Evolution (LTE for short) project was proposed by the 3GPP organization, the division of channels in the system has undergone major changes, and many dedicated channels have been reduced, and most communications are performed through public channels. In this way, it is very important to improve the call quality. [0003] In the prior art, load information (load information) processing is provided in the X2 interface protocol (X2 Application Protocol), through which adjacent base stations of the same frequency can notify each other of their load (load) and interference (interference) ) information, after the base station (eNB) obtains the informatio...
