Description
Technical Field
The present invention relates to the field of mobile communications, and in particular, to a method and an apparatus for processing uplink external interference of a base station.
Background
In the field of mobile communication, the quality of an uplink signal of a base station has a greater influence on the signal quality of the entire base station than the quality of a downlink signal, and therefore, the interference of the uplink signal of the base station is one of the important factors affecting the service quality of the base station. When the Uplink signal of the base station is seriously interfered, the useful signal sent by the user terminal is submerged by the interference noise, so that the base station cannot demodulate the Uplink signal because the useful signal and the interference noise cannot be distinguished, and further the performance of Uplink Packet Access (UPA) of the base station is reduced, and the user experience is influenced.
Currently, in a mobile communication system using a wide band mobile communication technology such as Code Division Multiple Access (CDMA), High Speed Uplink Packet Access (HSUPA), High Speed Downlink Packet Access (HSDPA), and Long term evolution Frequency Division duplex (LTE-FDD), a method for handling interference of Uplink signals of a base station is as follows: a Maintenance manager detects whether the average Total Wideband Received Power (RTWP) of each base station managed by an OMC is in a normal range of-106 dBm to-104 dBm or not through detection control software of the OMC, if not, the Maintenance manager further judges whether the base station is subjected to uplink external interference or not according to actual experience, and when the base station is judged to be subjected to the uplink external interference, the Maintenance manager determines an external interference source by using a test instrument, processes the external interference source according to the actual condition of the determined external interference source or processes the external interference source by using a government radio monitoring department; when the base station is judged to be not uplink external interference, a maintenance manager checks the parameters of the wireless configuration of the base station, or detects and tests the internal antenna feeder part of the base station to determine an internal fault or an internal interference source, and the interference is processed according to the actual condition of the determined internal interference source.
However, with the application of software radio technology in mobile communication, the situation that base station products of multiple systems and multiple frequency bands share the same antenna feeder system is quite common, and the types of external interference sources caused by the common situation are more and more, such as: passive Intermodulation (PIM), active intermodulation of the uplink repeater. Therefore, it may be difficult to identify whether the RTWP abnormality occurring in the base station is caused by external interference, and furthermore, when the method for processing the interference of the uplink signal of the base station is used, difficulties in positioning and processing an external interference source may be generated, so that it is difficult to improve the efficiency of interference processing and solve the service quality abnormality in time.
It can be seen that, in the current mobile communication system using the wideband mobile communication technologies such as CDMA, HSUPA, HSDPA, or LTE-FDD, the external interference sources are more and more complex, which increases the difficulty in locating the uplink external interference source of the base station, and makes it difficult to improve the interference processing efficiency, thereby affecting the data service processing performance of the base station and affecting the user experience.
