Telecom regulator TRAI said that it has receiving a number of call drop complaints from subscribers triggering the need to review existing quality of service rules to measure network performance at the district level and bring 4G-5G services also under its ambit.
The Telecom Regulatory Authority of India (TRAI) said that even with the technological advancement in mobile telecommunications and advancement in performance management tools, the quality of experience (QoE) of consumers has not improve as expect though such quality of service (QoS) requirements are support by technology standards.
TRAI said :
"Even with widespread coverage of 4G networks in the country and rollout of 5G services, there are increasing number of complaints of call drops, call muting, low data throughput etc. which raises question marks on the network design and provisioning of required network resources,".
The regulator has propose to tighten call drop parameters, call success rate etc under the quality of service rules.
Telecom Regulatory Authority of India said :
"The issues related to the quality of telecom services are not only reflected in consumer complaints but also find substantial mention in Parliament Questions,".
The regulator said that the Standards of Quality of Service for Wireless Data Services were notified in the era of 2G and 3G services wherein data services were deliver over circuit-switch networks and their QoS performance benchmarks were set based on the capability of underlying technology.
At present, packet core networks with LTE (4G), LTE-Advanced and 5G technology constitute more than 75% of the telecom network in the country.
TRAI said that the present QoS benchmark envisages latency to be less than 250 milliseconds (ms) for wireless data services and less than 120ms for wireline broadband service which are not in sync with the requirement of present-day applications.
TRAI said :
"The QoS parameters and benchmarks for voice and data services are technology agnostic in present regulations. The relevant terminology for 5G services has also been updated in draft regulations to monitor QoS performance of 5G,".
At present the quality of service is measure at telecom circle level which is generally equal to the size of a state level.
TRAI said the performance against some QoS benchmarks like network availability and drop call rates varies across districts.
Telecom Regulatory Authority of India said :
"Due to averaging over LSA, even very poor performance against QoS benchmarks in a few districts may not get reflected in performance reports. Therefore, in such cases, performance against QoS benchmarks may need to be reviewed at even district level if required,".
TRAI observe that though the service providers have launch mobile apps and web interfaces for customers, the consumer continues to face problems in registering their complaints due to complicated workflows.
It said that the number of calls at call centres has not reduced, and service providers are not able to meet current benchmarks in many cases even after the rollout of mobile apps.
TRAI Said :
"Further, there is a significant number of feature phones in the mobile network that cannot use mobile apps for the registration of complaints. Therefore, the Authority is not in favour of relaxing this benchmark for the sub-parameter accessibility of call centre numbers and percentage of calls answered by operators (voice to voice),".
Also TRAI has fix 20th September 2023 as the last date for comments and 5th October 2023 for counter comments of draft rules.
