Base station uplink external interference processing method and base station uplink external interference processing device

Abstract

The invention discloses a base station uplink external interference processing method and a base station uplink external interference processing device. The method comprises the following steps: an operation and maintenance center (OMC) sends an adjustment instruction to the base station; the base station calculates the attenuation value of a preposed attenuator according to the received interference adjustment instruction and an attenuation value which is obtained and calculated through an automatic gain control (AGC) attenuation algorithm by the base station, and the proposed attenuator is adjusted by the base station; the detected current received total wideband power (RTWP) value is subjected to bias subtraction operation by the base station according to the received interference adjustment instruction, and the corrected RTWP value is reported to the OMC. Through adoption of the technical solution provided in the base station uplink external interference processing method and the base station uplink external interference processing device, the speed rate and the quality of base station uplink data business can be quickly recovered, whether a signal received by the base station is an uplink mobile phone signal or an external interference signal can be determined, interference processing efficiency can be improved, and base station data business processing performance and user experience can be further guaranteed.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method and device for processing base station uplink external interference. Background technique [0002] In the field of mobile communication, the quality of the uplink signal of the base station has a greater impact on the signal quality of the entire base station than the quality of the downlink signal has on the signal quality of the entire base station. One of the important factors of quality. When the uplink signal of the base station is severely interfered, the useful signal sent by the user terminal will be submerged by the interference noise, resulting in the inability of the base station to demodulate the uplink signal due to the inability to distinguish the useful signal from the interference noise, resulting in the uplink data transmission of the base station (UPA , Uplink PacketAccess) performance degradation, affecting user experience.

Problems solved by technology

As a result, it may be difficult to identify whether the RTWP abnormality in the base station is caused by external interference, and then, when using the above-mentioned method for processing the interference of the uplink signal of the base station, it will cause difficulties in locating and processing the external interference source, so it is difficult to improve Interference handling efficiency and timely resolution of service quality anomalies

[0005] It can be seen that with the current mobile communication systems using broadband mobile communication technologies such as CDMA, HSUPA, HSDPA or LTE-FDD, there are more and more external interference sources and the situation is becoming more and more complicated, which makes it difficult to locate external interference sources in the uplink of the base station. increase, it is difficult to improve the efficiency of interference processing, which in turn affects the data service processing performance of the base station and affects the user experience
