India Gears Up to Launch Caller Name Display Service (CNAP)

▶

Stocks Mentioned :

Reliance Industries Limited
Bharti Airtel Limited

Short Description :

Telecom regulators TRAI and DoT are close to finalizing the rollout of the Calling Name Presentation (CNAP) service. This service will display the caller's name alongside their number on incoming calls, making mobile communication more transparent and helping to combat spam and fraud. It will be enabled by default for all users but can be disabled. The rollout will be phased, starting with 4G and 5G networks, and requires telecom operators to maintain secure caller databases. New devices sold in India will also need to be CNAP-compatible within six months of government notification.

Detailed Coverage :

The Telecom Regulatory Authority of India (TRAI) and the Department of Telecommunications (DoT) are advancing towards an agreement to introduce the Calling Name Presentation (CNAP) service across India. This service is designed to enhance transparency in mobile communications by displaying the caller's name on the recipient's screen along with their phone number during an incoming call.

TRAI has proposed, and DoT is largely in agreement, that CNAP should be enabled by default for all subscribers. However, users will retain the option to disable the service if they prefer. The service will function as a supplementary feature, adhering to global telecom standards, rather than a mandatory core service.

The implementation will be phased, commencing with newer network technologies like 4G and 5G, before extending to older 2G networks once the necessary technical infrastructure is ready. This approach aims to ensure a smoother deployment by prioritizing areas with advanced technology and minimizing disruption to existing systems.

CNAP is expected to serve as a significant deterrent against the rising prevalence of spam and fraudulent calls. To facilitate this, telecom operators will be responsible for setting up and maintaining secure databases that link subscriber names with their respective phone numbers. Subscribers who have opted for restricted caller identification will remain exempt from the service.

Additionally, TRAI has recommended that all new telecom devices sold in India must be CNAP-compatible within six months of the government issuing its notification. The regulator has also proposed a revision to the unified license definition for Calling Line Identification (CLI) to encompass both the caller's number and name, thereby integrating CNAP formally into the telecom licensing framework.

Impact: This regulatory development is significant for India's telecom sector. It will necessitate investments from telecom operators in infrastructure upgrades and secure database management, potentially leading to increased operational costs. For consumers, the service promises greater transparency in calls and a reduction in unsolicited communications. The phased rollout strategy aims to manage the technical transition effectively across the diverse network landscape. Rating: 7/10.
