Inter-RAT period report interval[ms] = D1000

escription:Interval that the UE reports inter-RAT measurement results to the RNC.In periodical report mode, the interval between two reports is the configured value. That is, the UE submits reports at intervals of the configured time. The value "NON_PERIODIC_REPORT" is, however, not recommended. In this setting, the UE behavior is not defined.Because the GSM RSSI measurement period is 480 ms, the inter-RAT periodical report interval should be longer than 480 ms. If InterPeriodReportInterval is excessively high, the handover judging time will be long, and handovers will be slower.The InterPeriodReportInterval is adjusted according to the configured GSM RSSI measurement compressed mode sequence. According to the current configured GSM RSSI measurement compressed mode sequence, the RSSI measurement of eight GSM cells can be finished in 480 ms, so the RSSI measurement of 16 GSM cells can be finished in 1000 ms. According to the protocol, not more than 32 inter-RAT neighboring cells exist, so the InterPeriodReportInterval can be set to 2000 ms if neighboring GSM cells exceeds 16.This parameter has impact on the Uu signaling flow. If the interval is too short and the frequency is too high, the RNC may have burden in processing signaling. If the interval is too long, the network cannot detect the signal change in time, which may delay the inter-RAT handover and thus cause call drops.GUI value range:NON_PERIODIC_REPORT(Non periodical reporting), D250~1 D500~2 D1000~3 D2000~4 D3000~5 D4000~6 D6000~7 D8000~8 D12000~9 D16000~10 D20000~11 D24000~12 D28000~13 D32000~14 D64000Actual value range:NON_PERIODIC_REPORT,250,500,1000,2000,3000,4000,6000,8000,12000,16000,20000,24000,28000,32000,64000Unit:msDefault value:D1000 escription:Timer length for inter-RAT measurement.After inter-RAT measurement starts, if no inter-RAT handover is performed when this timer times out, the inter-RAT measurement is stopped. In addition, the compressed mode is deactivated, if any; If the value is 0, you can infer that the inter-RAT measurement timer is not started.To set this parameter, you need to consider the following factors:This parameter aims to prevent that the handover conditions are not met and the compressed mode is kept for a long time when the UE does not move or is moving in a low speed. The service quality is adversely affected and the total available capacity decreases if the compressed mode is kept for a long time.Most inter-RAT handovers can be finished within 60 s.As for the impact on network performance,If the InterRATMeasTime is excessively low, the UE cannot finish inter-RAT handovers. If InterRATMeasTime is excessively high, it cannot help improve the service quality. In actual networks, statistics can be made to obtain the delay for a successful inter-RAT handover so as to get a proper value of InterRATMeasTime that satisfies most UEs.
