Concrete:
Step a:OMC provides RTWP value by detecting control software, judges whether RTWP value corresponding to described base station returns in the normal range (NR), if normally, and execution in step b then; If undesired, determine that then the interference of described base station is non-up external disturbance, the end process flow process.
Here, the described interference of determining described base station be non-up external disturbance can for: the base station internal fault occurs or wireless parameter arranges unusually, specifically does further detection by the maintenance management personnel according to prior art.
Step b: the detection control software by OMC checks whether the UPA speed of base station is in normal range (NR), if UPA speed is normal, the interference of then determining described base station is up external disturbance, and got rid of the up external disturbance that described base station is subject to, end process flow process; If UPA speed is undesired, execution in step c then.
Here, it is interior for to judge or to judge according to the professional acceptance index of the actual regulation of operator according to practical experience that described UPA speed is in normal range (NR), such as, can will be decided to be normal range (NR) more than or equal to 1Mbps.
Step c: the interference of determining described base station is non-up external disturbance, does further detection by the maintenance management personnel according to prior art.
Here, the described interference of determining described base station be non-up external disturbance can for: the base station internal fault occurs or resource distribution is unusual, is specifically determined according to prior art by the maintenance management personnel.
