Hello there community members!
I would like to talk about KPIs, which are important tools for monitoring the quality of performance and obtaining statistical reports on performance efficiency.
KPI
A key performance indicator is a numeric or text value that measures the actual achievement of a particular unit's activity. KPIs are generally used by dashboards that help us monitor the progress of their activity.
Examples of some important KPI
1- RRC Setup Success Rate
The RRC setup success rate is calculated supported the counter within the eNodeB once the eNodeB receives associate degree RRC connect request from the UE.
2- ERAB setup success rate
ERAB Setup Success Rate KPI shows the success rate of ERAB to access all services together with VoIP in a very cell or radio network.
3- Call Setup Success Rate
Call setup success rate A KPI decision setup indicates the likelihood of success of all services on the cell or radio network. The KPI is calculated by multiplying the RRC setup success rate, KPI, S1 signal communication success rate, KPI, and ERAB KPI success rate.
4- Drop calls
VoIP decision drop arises once the VoIP ERAB version is abnormal.
5- Intra-Frequency Handover Out Success Rate
Intra-frequency delivery success rate Our KPI shows the success rate of intra-frequency delivery of a frequency among the native cell or radio network to a neighboring cell or intra-frequency radio network. among the frequency Ho is enclosed in one completely different eNodeB or eNodeB cell.
6- Inter-RAT Handover Out Success Rate (LTE to WCDMA)
RAT delivery success rate shows the success rate of KPI HO from LTE cell or radio network to WCDMA cell.
7- E-UTRAN IP Throughput
TTo achieve a throughput measurement that is independent of the burst motion pattern, it is important to ensure that idle gaps are not included between the incoming data in the measurements. This should be done by considering each burst of data as a single sample. ThrpVolDl is the volume at the IP level and ThrpTimeDl is the time elapsed for Uu to transfer the volume contained within the ThpVolDl.
8- E-UTRAN IP Latency
A measurement showing how E-UTRAN affects the delay experienced by the end user.
The time from receiving an IP packet until sending the first packet via Uu.
To achieve delay measurement that is independent of the IP data block size, only the first packet sent to Uu is measured.
To find the delay for a given packet size, the IP throughput meter can be used with the IP latency (after the first block in Uu, the remaining time of the packet can be calculated using the IP throughput meter).
9- E-UTRAN Cell Availability
showing E-UTRAN cell availability.
The percentage of time a cell is considered available.
As for identifying the cell as available, it should be considered available when eNodeB can provide an E-RAB service in the cell.
10- Mean Active Dedicated EPS Bearer Utilization
This KPI describes the ratio of the average number of allocated active EPS carriers to the maximum number of active dedicated EPS carriers provided by the EPC network, and is used to evaluate the performance of using the EPC network.
This KPI is given by the average number of EPS carriers allocated in active mode divided by system capacity.
The average number of concurrent online sessions answered combined with the maximum number of sessions the network provides can reflect system resource usage. If the KPI value is too high, this indicates that the system capacity is insufficient, and it must be increased. This KPI focuses on the width of the network.
Thanks,
