KPI - Key Performance Indicators

Hi,

          KPI tells the performance of a network on a daily/weekly/monthly basis, which helps to improve the network, so that operator & customer both enjoys the service at its most.

Key Performance Indicators for Telecom Industry are :-

Systems and Network Performance Analysis / Capacity Planning
  • Availability
  • Grade of service
  • Service life of equipment
  • Bit error ratio (data, bits & elements transfer)
  • Bit rate (data, bits and elements transfer)
  • Downtime / Time out of service
  • Call completion ratio
  • Cost of support systems
  • Cost of operational systems
  • Average call length
  • Analysis of ASR routes
  • Network traffic, congestion
  • Idle time on network
  • Dropped calls
Quality / Usage (Airtime): Analysis of the volume of successful calls
  • Mean Opinion Score
  • Service
  • Duration of calls
  • Billed amount on each call
Coverage
  • % of land covered with services
  • % of population covered with services
  • Average land unavailable to services
  • Average population unavailable to services
  • Access to customer service
Faults and complains (Trouble tickets analysis)
  • % of open and level of escalation priority required
  • % closed
  • Mean time to resolved
  • Work in progress
  • Customer service level statistics
Customer Analysis
  • Customer segmentation
  • Analysis of subscriptions
  • Top N customers
  • Churn (No. of Subscriber who stopped using Services or left particular network)  
ASR (Answer Seizure Ratio) - Number of successfully answered calls divided by the total number of calls attempted (seizures) multiplied by 100.
(Answer / Seizure) * 100 = Answer Seizure Ratio.
Standard Value = 40% - 45%. 

MOU (Minutes of Usage) per Subscriber – It calculates the Total Minutes used in a Network divided by the number of subscribers. 

CCR (Call Completion Ratio) - Total no of calls completed / Total no of calls attempted * 100%
Higher the ratio is better. 
Standard Value > 98%.

LUSR (Location Update Success Rate) - Its a ratio of no.of times mobiles update its location successfully to the no.of times mobiles request network for Location update.
LUSR = (Location Update Success / Location Update Request)*100.
Standard Value >= 98%.

PSR (Paging Success Rate) - Its a ratio of no.of times network successfully find the mobiles to the no.of times network tries to locate the mobiles within its area.
PSR = (No.of Network Paging Response / No.of Network Paging Attempts)*100.
Standard Value >= 92%.


More Information from Readers are Expected !!!

  2. Hi,

    Many different KPI's are possible depending on Network Elements like MSC, BSC, STP, NGN, etc.

    Kindly let me now any specific KPI you are looking for, on which i can probably help.

    Thanks

  7. To Ashish..

    Is missed call or B-number busy (no answer) parameters associated to CCR

  8. Hi Yash,

    B-Number Busy or Misses Call doesn't effect CCR, since CCR depends on ACM messages, while both effects ASR.

    Feel feel to revert for queries....

  11. Hi,
    For Core CS KPI: SMMT SR always differ from SMMO SR, why?

    ReplyDelete
  12. hi, Thank you for good information. Can you share with us more information about each one the KPI for Telecom Industry listed above! For example, description/definition for the KPI, variables used in the formula to calculate it, the formula itself used for the calculation, and frequency for measurements.

  14. HI,

    Can you tell me how to improve the major KPIs such as success rate, RAB setup rate, RRC, call blocking etc.

    And if you have some information on the KPIs that are being sued by the Major operators, it will be really helpful.

  15. Dear
    what are the things need to check in MSC side if it is PSR is poor..??

  17. @Hameed,
    Paging repetition value (i.e. how many times the paging is repeated)

    Paging repetition timer value (i.e. after how many seconds the paging is repeated)

    Check the LAC where the paging SR is lower and then check for the cell area where the PSR value is low.

    Using that coverage can be improved in that area.

    SMS MT attempts should not be combined with the voice calls attempts to calculate the paging SR.

  18. @Guru,

    Because SMSC would keep trying to deliver the SMS, as per the defined time interval (which is defined in SMSC).

    So if the SMS is not successful at the first attempt then there would be many attempts from SMSC. That makes the SMS-MT SR to be lower than SMS-MO.

  19. Hi, it would be great favor if somebody emphasizes more on CCR. like in our switch the CCR value is is between 60%-90% which we wants to maintain at >=90% all the time. SO being a switch guy what all the steps i should take to improve this figure at 90% and above.

  20. Hi Inderjeet,

    CCR is Call Completion Rate & its totally depends on one of the ISUP messages i.e. ACM messages,

    %CCR = (ACM / IAM) * 100

    Good value for the same is > 98%,

    To Improve following steps can be taken :-

    1. Check for announcement mapping i.e. check for every release cause whether announcement mapping is there or not & proper announcement mapping should be there.

    Specially check for announcement mapping in case of Roaming Subscribers.

    2. If possible activate Early-ACM or Pre-ACM.

    3. Check for cases in trace in which ACM not receiving, generally for User Busy case, directly REL (User Busy) is send after IAM, avoiding ACM message, to save some resources.

  21. Improvement Plans:
    • Continuous Monitor of C7 Signaling utilization and it should me optimize as much as possible.
    • For Narrow Band Signaling the utilization should not go above 0.3 Erl. And for High Speed Signaling the utilization must be kept below 0.4 Erl(Per time slot).
    • Trunk route utilization should not go above 80% and there should not be any congestion in the trunk route.
    • There should not be any internal congestion in the switch.
    • EOS(End of Selection) must be defined properly in every switch. Wrong or No EOS leads to repeated attempts and this repeated attempts will lead to higher BHCA and this higher BHCA will results to Higher Processor Load.
    • Announcement must be mapped properly in the switch. Wrong or no announcement leads to repeated attempts and this repeated attempts will lead to higher BHCA and this higher BHCA will results to Higher Processor Load.
    • Monitor and regulate high utilization of hardware devices such as: ECDH, ASDH, CCD, etc.
    • B-Number table should be properly defined and there should not be unnecessary forwarding and looping in the table.
    • Signaling should be properly defined and there should not be unnecessary looping in the signaling.
