Problems solved by technology

[0004] However, with the application of software radio technology in mobile communications, it is very common for base station products of multiple standards and frequency bands to share the same antenna and feeder system, and the resulting external interference sources are also increasing. For example: passive intermodulation (PIM, Passivelnter-Modulation), active intermodulation of uplink repeaters; Efficiency of external interference, which affects the commissioning and acceptance of the site
[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 more difficult to locate external interference sources in the uplink of the base station. , so it is difficult to improve the processing efficiency of uplink external interference, which will degrade the performance of the uplink data service of the base station and affect the user experience

Embodiment 1

[0055] It is assumed that both the duplex module at the antenna feeder end and the duplex module at the main equipment end realize the uplink and downlink signal separation function through the duplex filter in the prior art, and the frequency bands of the two bandpass filters of the duplex filter are respectively determined according to the communication system in which they are located. The receiving and transmitting frequency bands are set, and the device for processing the uplink external interference of the base station in the present invention, such as figure 2 shown; among them,

[0056] The antenna-feeder duplex module further includes: an antenna-feeder splitter, an antenna-feeder uplink bandpass filter, and an antenna-feeder downlink bandpass filter; wherein,

[0057] Antenna feeder splitter combiner, used to split the uplink signal sent by the antenna feeder system of the base station, and send the split uplink signal to the uplink bandpass filter of the antenna fe...

Embodiment 2

[0064] Assuming that both the duplex module at the antenna feeder end and the duplex module at the main equipment end realize the function of separating the uplink and downlink signals through the circulator in the prior art, the device for processing the uplink external interference of the base station in the present invention is as follows: image 3 shown; among them,

[0065] The antenna-feeder duplex module provides the uplink and downlink signal separation function by using the unidirectional transmission characteristic of the circulator, and sends the uplink signal sent by the antenna feeder system of the base station to the uplink attenuation module; correspondingly, the uplink attenuation module The received uplink signal is attenuated according to the preset attenuation value, and the attenuated uplink signal is sent to the duplex module at the master device side; the duplex module at the master device side provides uplink and downlink signals by using the unidirection...

Abstract

The invention discloses a base station uplink external interference processing apparatus, a base station uplink external interference processing method and a base station uplink external interference processing system. The apparatus comprises an antenna feed end duplexing module, an uplink attenuation module, and a main device end duplexing module, wherein a signal sent by an antenna system in a base station is subjected to uplink and downlink signal separating operation by the antenna feed end duplexing module, and a separated uplink signal is sent to the uplink attenuation module by the antenna feed duplexing module; the uplink attenuation module is used for attenuating the uplink signal sent by the antenna feed end duplexing module and is used for transmitting the attenuated uplink signal to the main device end duplexing module; the main device duplexing module is used for transmitting the attenuated uplink signal to main equipment in the base station, wherein the attenuated uplink signal is sent by the uplink attenuation module. Through adoption of the base station uplink external interference processing apparatus, the base station uplink external interference processing method and the base station uplink external interference processing system, uplink and downlink signals can be separated, the uplink signal alone can be subjected to attenuation processing, and that the interference is internal abnormity or external interference can be determined; the speed rate and the quality of base station uplink data can be recovered, the uplink signal and the external interference received by the base station can be distinguished, interference processing efficiency can be improved, and the performance of base station data business and user experience can be further guaranteed.

Description

technical field [0001] The invention relates to anti-jamming technology in mobile communication, in particular to a method, device and system for dealing with uplink external interference of a base station. 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. Decrease, reducing the data upload rate of uplink data services, thereby affecting user experience. [0003] Currently, Code Division Mu...
