PTA: Cellular Mobile Operators’ Quarterly Quality Of Service Survey Results – 2018

General

In the year 2018, Pakistan Telecommunication Authority (PTA) has conducted quarterly Quality of Service (QoS) survey jointly with Cellular Mobile Operators (CMOs) using NEMO automated QoS tool. During the period, a total of twenty-seven (27) cities of Pakistan including AJK, have been surveyed. The names of these cities are as under:

DATA – KEY PERFORMANCE INDICATORS 

 The performance of data services of CMOs has been checked by measuring User Data Throughput and Signal Strength Key Performance Indicators (KPIs).

USER DATA THROUGHPUT

This KPI defines user data rate (Internet speed) to be provided by NGMS operators to mobile users across the coverage areas. The data throughput results of all NGMS licensees are as under:

 Throughput (3G)

Throughput (4G)

SIGNAL STRENGTH

This KPI defines Received Signal Code Power (RSCP) for 3G and Received Signal Receive Power (RSRP) for 4G and denotes the power measured by a receiver on a particular physical communication channel. It is used as an indication of signal strength, as a handover criterion, in downlink power control, and to calculate path loss”. The Signal Strength for NGMS licensees are as under:

Received Signal Code Power (RSCP)

Received Signal Receive Power (RSRP)

VOICE – KEY PERFORMANCE INDICATORS

The performance of voice services of CMOs has been checked by measuring Network Down Time/Network Accessibility, Grade of Service, Service Accessibility, Call Connection Time, Call Completion Ratio, End-to-End Speech Quality and Session Abnormal Release Rate Key Performance Indicators (KPIs).

NETWORK DOWN TIME

“The probability that mobile services are neither available to an end customer nor display of the network indicator on the mobile equipment”.

GRADE OF SERVICE (GOS)

 “Grade of Service is probability that the end customer cannot access the mobile services when requested if it is offered by display of the network indicator on the mobile phone. In simple words, Grade of Service is Network Blocking”.

SERVICE ACCESSIBILITY

“Service Accessibility is the probability that the user can access the desired service. A given network accessibility is a precondition for this phase”.

CALL CONNECTION TIME

“Call Connection Time is the time between sending of complete call initiation information by the caller and in return receipt of call setup notification. In simple words, it is time between dialing a number and hearing ring-back tone”.

CALL COMPLETION RATIO

“Call Completion Ratio is the probability that a service, once obtained, will continue to be provided under given conditions for a given time duration or until deliberately terminated by either caller (A-party) or receiver (B-party). In simple words, this KPI provides information about Call Drops”.

END-TO-END SPEECH QUALITY

End-to-End Speech Quality is the degree of speech quality that a listener perceives at the terminal/mobile with a talker at the other end. In simple words, it provides information about clarity of voice.

SESSION ABNORMAL RELEASE RATE

“A measurement that shows how often an end-user abnormally loses an Enhanced Radio Access Bearer (E-RAB) during the time the E-RAB is used.”

SMS – KEY PERFORMANCE INDICATORS

 The performance of SMS services of CMOs has been checked by measuring SMS Success Rate and End-to-End SMS Delivery Time Key Performance Indicators (KPIs).

SMS Success Rate

SMS Success Rate is the probability that the short message is delivered successfully, end-to-end when requested and display of the relevant information on the mobile phone. It provides information about successful delivery of SMS.

END-TO-END SMS DELIVERY TIME

End-to-End SMS Delivery Time is the time between sending a short message to a short message center and receiving the very same short message at intended mobile phone (receiver). It provides average time taken for delivery of short message from sender to recipient.
