Background technology

3G (Third Generation) Moblie standard (3GPP, 3Generation Partnership Project) protocol definition: SIR difference (Error) is wireless link (RL, Radio Link) real-time SIR and radio network controller (RNC, Radio Network Controller) target signal interference ratio (the Target SIR setting, Target Signalto Interference Ratio) difference, SIR Error can be used as the adjustment foundation of external circule power control.

Generally, the real-time Block Error Rate that RNC obtains according to statistics (BLER, Block Error Ratio) is adjusted the Target sir value of RL, makes the BLER value of uplink service approach target BLER value.But in some cases, such as user terminal (UE, User Equipment) in weak signal area, or base station (Node-B) is while deliberately suppressing SIR, the SIR of RL cannot catch up with Target SIR, now, the BLER of the uplink service of RL can be greater than the target BLER value of being set by RNC, in this case, if RNC continues to raise Target sir value without any meaning, and once the signal conditioning of UE, return to suddenly better, will cause because of the slow decreasing of Target SIR the waste of capacity.Therefore, 3GPP requires Node-B SI reporting R Error value to do external circule power control reference to RNC, when SIR Error value is greater than certain thresholding, even if BLER value is greater than target BLER value, also no longer raises SIR Target value.

At present, in communication system, by measuring up link SIR Error, link quality of uplink signal is detected.Conventionally, base station application part (NBAP, the Node-BApplication Part) dedicated process by IUB mouth that reports of SIR Error is realized, comprise special measurement initialization, the process such as report, stop, wherein, report process will pass through the mutual of user's face and chain of command.Yet this mode that reports is wasted IUB mouth signalling bandwidth, has increased chain of command load.
