ISLAMABAD: The government has notified the “Regulation 2021 on the quality of service (QoS) of the cellular mobile network”, which will apply to all licensees of cellular mobile communication service and new generation mobile services (NGMS) with the aim of identifying minimum quality of service standards and associated measurement, reporting and archiving of mobile network coverage, voice, SMS and mobile broadband service.
Faced with growing concerns about QoS parameters including call loss, call quality and data rate, the Pakistan Telecommunications Authority (PTA) decided to change the QoS regulation of the network. cellular mobile.
QoS refers to the ability of a network or service to satisfy the end user and is primarily related to those aspects of services that are directly experienced by consumers.
Compliance reports must be submitted against the quality of service parameters defined in this regulation.
MoIT & T publishes NGMS auction policy guideline
Each mobile communications service and holder of an NGMS license must at all times meet or exceed the minimum quality of service requirements specified in their respective licenses and in this Regulation.
Network accessibility – the likelihood that mobile services will be available to an end customer by displaying the network indicator on the mobile test equipment for the duration of the samples.
Network accessibility should be 99 percent.
Percentage of time the mobile device reports “no service” or “emergency” as a technology served during the test drive.
“No service” or “emergency” is the period during which the mobile services are not available to an end customer or the display of the network indicator on the mobile equipment.
Network downtime – the likelihood that mobile services will not be available to the end customer.
The PTA decides to modify the QoS regulations of the mobile cellular network
Network downtime should be 1%.
Network downtime should be measured from the operator’s network management system (NMS) for an average of one month, i.e. at all external sites deployed by the operator in the study area and also in any other area, i.e. district, Tehsil, etc., provided by the Authority.
Call establishment success rate – “The probability that the end customer will successfully access the mobile service when asked if it is offered by the display of the network indicator on the mobile equipment”.
Call setup success rate should be 98%.
Call setup time – The time between sending the complete call initiation information by the caller (Part A) and receiving the call setup notification back.
The call setup time shall be
Call completion rate – the probability that a service, once obtained, will continue to be provided under given conditions for a given period of time or until it is deliberately terminated by subscriber A or subscriber B. Call completion rate must be greater than 98%.
Call Abandonment Rate – the likelihood that a service, once obtained, will not continue for a given length of time or be deliberately interrupted by either A or B.
Call abandonment rate
End-to-end speech quality: The degree of speech quality that a listener perceives at the terminal with a speaker at the other end.
The average opinion score should be> 3.
The end-to-end quality of service (mean opinion score) is represented by the mean value of the ITU-T P.863 “Objective analysis of perceptual listening quality” (POLQA) predicts the MOS of all speech samples in successful calls.
The measurement will be based on the latest version of ITU-P.863 to achieve the correct relative quality of service between VoLTE, HD-Voice and legacy narrowband telephony.
SMS Success Rate – “The likelihood of the short message service being delivered successfully, end-to-end on demand and displaying relevant information on mobile equipment.”
The SMS success rate should be 99%.
End-to-End SMS Delivery Time – The time between sending a short message from a mobile terminal (A-Party) and receiving the same short message on the intended mobile terminal (B-Party).
End-to-end SMS delivery time should be 12 seconds.
As the subscriber base increases, customer dissatisfaction increases and complaints against the network also increase.
Growing concerns about various QoS parameters, in particular call loss, call quality and data rate, have been observed recently.
QoS parameters can be measured both from network monitoring terminals and from field surveys via drive tests. With the adaptation of 3G and 4G technologies, it is high time to set benchmarks / thresholds for mobile telephone operators (CMOs), which they must respect to ensure consumer satisfaction.
The PTA said the 2011 QoS regulations and subsequent changes in 2012 have scope and applicability to all cellular mobile communication services to identify minimum quality of service standards and associated metrics.
However, with the allocation of NGMS licenses, regulations must be changed by NGMS licensing and taking into account international best practices and ensuring the delivery of the best quality of service to consumers of mobile services.
Existing regulations provide key performance indicators (KPIs) and measurement procedures, which mainly relate to voice service and SMS.
The regulations have not defined any KPIs for NGMS or mobile broadband service. The QoS KPIs in the QoS regulation of the mobile cellular network 2011, modifications of the voice and SMS services, are suggested in the existing QoS KPIs regarding its measurement procedure and its threshold values, etc.
NGMS licensing paved the way for the introduction of new QoS KPIs for voice and mobile broadband.
Suggested QoS KPIs for inclusion in the QoS Policy are listed below.
