Problems solved by technology

Therefore, this rough estimate cannot accurately determine whether the current interference source is actually causing interference, so it is also impossible to accurately determine the interference source, and this method is only for the judgment of the base station that generates interference. For the target base station, although There is interference but the source of the interference cannot be determined

Embodiment 1

[0055] This embodiment describes the situation where there is a direct interface in the LTE system, specifically the situation where an interference indication is sent through the X2 interface, such as image 3 shown. The source base station eNB1 predicts that the UE under the jurisdiction of Cell1 will cause uplink interference to the Cell2 under the jurisdiction of the target base station eNB2. eNB1 and eNB2 can be macro base stations or home base stations, and there is a direct interface such as X2 between eNB1 and eNB2. The direct interface may be established on the connection between eNB1 and eNB2. If eNB2 is a home base station that accesses the core network through a home base station gateway, the direct interface can also be established on the connection between eNB1 and the home base station gateway of eNB2 and the connection between the home base station gateway and eNB2; The base station gateway accesses the home base station of the core network, and the direct int...

Embodiment 2

[0067] This embodiment describes the situation where there is a direct interface in the UMTS system, specifically the situation where an interference indication is sent through the Iur interface, such as Figure 4 shown. The source network element RNC1 predicts that the UE under the jurisdiction of the cell Cell1 will cause uplink interference to the Cell2 under the jurisdiction of the target network element RNAC2. RNC1 and RNC2 may be ordinary macro RNCs or home base stations. In this embodiment there is a direct interface Iur between RNC1 and RNC2. The Iur interface can be established on the connection between RNC1 and RNC2; if RNC2 is a home base station connected to the core network through a gateway, it can also be established on the connection between the gateway of RNC1 and RNC2 and the connection between the gateway and RNC2; if RNC1 is a home base station connected to the core network through a gateway, and may also be established on the connection from RNC1 to the g...

Embodiment 3

[0069] This embodiment describes the situation of forwarding the interference indication information through the core network in the LTE system, specifically the situation of sending the interference indication through the MME, such as Figure 5 shown. The source base station eNB1 predicts that UEs under the jurisdiction of Cell1 cause uplink interference to Cell2 under the jurisdiction of the target base station eNB2. eNB1 and eNB2 can be macro base stations or home base stations. S1 is established between eNB1 and eNB2 and the core network element MME. interface. If eNB1 is a home base station connected to the core network through the home base station gateway, this S1 interface can also be established between eNB1 and the home base station gateway and between the home base station gateway and the MME; if eNB2 is connected to the core network through the home base station gateway The home base station, the S1 interface may also be established between the eNB2 and the home b...

Abstract

The invention discloses an interference source determination method, which comprises that: a target network element receives interference indication information from a source network element, and determines an interference source according to the interference indication information. The invention also discloses an interference source determination system, which comprises a determination unit, wherein the determination unit is used for receiving the interference indication information from the source network element and determining the interference source according to the interference indication information by the target network element. By the method and the system provided by the invention, the interference source can be accurately determined.

Description

technical field [0001] The invention relates to wireless cellular communication technology, in particular to a method and system for determining interference sources. Background technique [0002] Interference control is an important issue in wireless communication systems. Inter-cell interference will be more prominent in the case of co-frequency deployment of cells, and adjacent-frequency interference also exists between cells in the case of different frequencies. The methods to solve the interference are different according to the interference generation scenarios. For example, the typical method to deal with the downlink interference at the cell edge is to use the frequency reuse technology to complete. For the macro base station network, interference elimination and minimization can be achieved through common interference solving methods and reasonable planning. However, with the development of wireless technology, the concept of Femto cells has been introduced. The i...
