Section: A.9 Monitoring of RF performance
Content: RF Performance reflects the cell loading levels and abnormal conditions. In the Downlink, Power Resources are managed by the EUTRAN Cell(RAN). More Power Resources may help in increasing the Capacity of the System. Hence, there the power resources could be effectively used to optimize the Capacity of the System. Hence there is a need to keep monitoring the Power Resource Utilization in % and also in absolute terms. Monitoring of the quality of RF signal in the cell is useful for the purpose of NW planning and overall service quality assessment. Measurements of Channel Quality Indicator (CQI) reported by UEs is a useful metric reflecting RF signal quality and service quality. Timing advance measurements reflect the distance of the UE from the cell antenna. This information reflects the optimality of the cell antenna location with respect to the cell traffic and is useful in the NW planning process. Monitoring interference, both uplink and downlink, is an important aspect of monitoring RF performance. For this purpose, monitoring of UL interference power is useful. Interference signals in a number of different ways, including frequency, frequency band, direction of interfering signals, etc. can also be classified by System internal interference and External interference. By efficient frequency planning and careful Selection of base station locations, the impact of interference signal can be effectively controlled within an acceptable scope.uplink interference disturbs the base station receiver. Once the base station receiver is compromised, it leads to receiving code errors for the whole base station and the site’s entire service area is degraded including its network and service. Of course, customer satisfaction is negatively impacted. So it is very useful to monitor uplink interference of communication system to do network optimization.
