Zong achieves the best Quality of Service – According to PTA Survey

The 4G mobile operator, Zong has declared the best performer in almost all voice and data service quality elements amongst all local mobile operators in Pakistan, as per official results announced by PTA on its website.

PTA conducted the survey for all aspects of network performance, out of which Zong stood the leading network operator in terms of both voice and data services. Zong led the survey in network accessibility, grade of service, call connection time, call completion ratio, the end to end speech quality, SMS success rate and the end to end SMS delivery time. Apart from this, Zong also stood first in signal strength and data throughput.

Commenting on this achievement, Zong’s Chairman and CEO, Liu Dianfeng said “Zong is not only a network operator, we consider ourselves much more than just that. Improving the lifestyle of our Pakistani people is our core mission. We are working very hard to continue to improve our voice and data services and be able to serve the Pakistani community with newer and better products through our most advanced 4G technology. Having enough confidence in the local market, Zong will persistently invest in our 4G network to innovate more solutions and help support multiple walks of life in education, health, security, government and the public sector.”

We will continue to enhance our network by bringing value to our voice and data services through our 4G connection, at the same time update our 2G to 3G and 4G network in terms of its wide coverage and signal strength to provide far better customer satisfaction in the market. Through our customers, we understand that 4G is our future, and we will invest in our future to make it more valuable for all of us”, he added.

Next Generation Mobile Services – Key Performance Indicators

1. 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 for all NGMS licensees was checked using NEMO Invex-I tool at Islamabad, Rawalpindi, and Peshawar the results of which are as under:

User data “throughput” of all NGMS operators is higher than the benchmark set in their respective licenses. Data throughput of Zong is the highest followed by Mobilink, whereas data throughput of Ufone is the lowest among all NGMS operators.

2. Signal Strength

This KPI defines minimum outdoor signal strength. The higher the signal strength, the better data and voice services available to the mobile users would be.

The signal strength of all the NGMS operators is above the benchmark revealing good coverage in the majority of the covered areas. The lower the value of signal strength on negative axis, the higher is the signal strength.

Note: While examining the above two parameters, it reveals that though the overall signal strength of Ufone and Telenor networks is comparatively better than those of Zong and Mobilink because of more frequency spectrum used by Zong and Mobilink for NGMS, their quality is superior.

Cellular Mobile Services – Key Performance Indicators

1. Voice Services

a. Network Accessibility

“Network Accessibility is the probability that mobile services are available to an end customer by display of network indicator on the mobile phone throughout the entire duration of usage”.

Network Accessibility of all the mobile operators is satisfactory.

b .Grade of Service (GoS)

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

All mobile operators are meeting Grade of Service.

c. 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”.

The call connection time of all the mobile operators is not satisfactory.

d. 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.

Call Completion Ratio for Mobilink and Ufone is below the required standard, whereas other three mobile operators are meeting the standard.

e. 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 the clarity of voice.

End-to-End Speech Quality of all the mobile operators is above the standard.

2. SMS Services

a. 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.

SMS success rate for Mobilink and Warid Telecom is below the standard, whereas other mobile operators are meeting the standard.

b. 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.
