Embodiment 1

[0028] Such as figure 1 Shown is a schematic flow chart of the interference detection method in Embodiment 1 of the present invention. The method includes the following steps:

[0029] Step 101: The interference detection device receives the Reference Signal Receiving Power (RSRP) and the Signal to Interference plus Noise Ratio (SINR) of each user terminal reported by the base station.

[0030] The RSRP and SINR of each user terminal reported by the base station to the interference detection device are determined through the following steps:

[0031] The first step: the base station receives the RSRP, Reference Signal Receiving Quality (RSRQ) and received signal strength indication (Received) of the user terminal reported by each user terminal in the cell it serves through the Measurement Report (MR) Signal Strength Indicator, RSSI).

[0032] In the first step above, each user terminal in the cell periodically measures the RSRP, RSRQ, and RSSI of the cell according to the instructions...

Embodiment 2

[0088] Such as figure 2 Shown is a schematic structural diagram of an interference detection device according to Embodiment 2 of the present invention. The interference detection device may be an OMC device of an operation and maintenance center or other third-party equipment, which is not limited in the embodiment of the present invention. The interference detection device It includes a receiving module 11, a determining module 12 and a detecting module 13, where:

[0089] The receiving module 11 is configured to receive RSRP and SINR of each user terminal sent by the base station; the specific source and determination of the RSRP and SINR are detailed in step 101 in the first embodiment of the present invention, and will not be repeated here.

[0090] Preferably, the receiving module 11 is also used to receive carrier frequency information and location information used by each user terminal sent by the base station.

[0091] The determining module 12 is configured to determine the...

Embodiment 3

[0098] Such as image 3 Shown here is a schematic structural diagram of an interference detection system in Embodiment 3 of the present invention. The interference detection system includes a base station 21, an interference detection device 22, and at least one user terminal 23:

[0099] The base station 21 is configured to receive RSRP, RSRQ and RSSI reported by the user terminal, determine the SINR of the user terminal according to the RSRP, RSRQ and RSSI, and send the reference signal received power RSRP and SINR of each user terminal to the interference detection device.

[0100] The interference detection device 22 is configured to receive the reference signal received power RSRP and the signal to interference plus noise ratio SINR of each user terminal sent by the base station, and determine the numerical interval to which the RSRP of each user terminal belongs and the numerical interval to which the SINR belongs. The value interval to which the RSRP belongs determines the qu...

Abstract

The invention discloses an interference detection method, device and system. The method includes the steps that the RSRP and SINR, which are reported by a base station, of each user terminal are received; mass parameters of the RSRP and mass parameters of the SINR of each user terminal are determined, and it is determined that interference exists in a system when the number of user terminals meeting the condition that the mass parameters of the RSRP of the user terminals do not correspond to the mass parameters of the SINR of the user terminals in a certain area is larger than a preset threshold value. According to the technical scheme, because the RSRP and SINR of all the user terminals in a cell covered by the base station are utilized and are analyzed according to the incidence relation between the RSRP and the SINR, whether interference exists in the system or not can be detected objectively, comprehensively and accurately.

Description

Technical field [0001] The present invention relates to the field of mobile communication technology, in particular to an interference detection method, equipment and system. Background technique [0002] In the existing mobile communication network, the user terminal needs to interact with the wireless network controller through the base station to realize the required mobile communication services. However, there is often interference during the communication between the base station and the user terminal, and the interference is detected. And elimination is an important guarantee for the quality of communication services. [0003] At present, in order to ensure the communication quality of mobile communication networks and provide users with better network services, the following methods can be used to detect interference in the communication process: [0004] Method 1: Use Drive Test (DT) to find out whether there is interference from other signals in the drive test area. [0005...
