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

Embodiment Construction
[0035] The basic idea of the present invention is: the base station receives the interference adjustment instruction sent by the OMC; the base station calculates the attenuation value of the pre-attenuator according to the received interference adjustment instruction and the attenuation value calculated by itself using the AGC attenuation algorithm , adjust the pre-attenuator; the base station subtracts the detected current RTWP value according to the received interference adjustment instruction, and then reports it to the OMC.
[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0037] A method for dealing with base station uplink external interference provided by the present invention is as follows: figure 1 shown, including the following steps:
[0038] Step 101: the base station receives the interference adjustment instruction sent by the OMC.
[0039] Here, the interference a...

The invention discloses a method and device for processing uplink external interference of a base station, wherein the method includes: an operation and maintenance center (OMC) sends an adjustment instruction to the base station; the base station uses the automatic gain control ( The attenuation value calculated by the AGC attenuation algorithm is calculated to obtain the attenuation value of the pre-attenuator, and the pre-attenuator is adjusted; the base station adjusts the detected current wideband received total power (RTWP) according to the received interference adjustment instruction ) values are subtracted and then reported to the OMC. By adopting the technical solution provided by the present invention, the rate and quality of the uplink data service of the base station can be quickly restored, and whether the signal received by the base station is an uplink mobile phone signal or an external interference signal can be distinguished to improve the efficiency of interference processing, thereby ensuring the data service processing performance of the base station and user experience.
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.
