Indian telecom stakeholders have urged the Telecom Regulatory Authority of India (TRAI) to ensure that network slicing — a core 5G capability — does not dilute the country's existing net neutrality framework.

The call came through written submissions to the regulator, which has been examining how 5G-era network management techniques interact with the non-discrimination principles India codified in 2016. Industry participants, including mobile operators, equipment vendors and civil society groups, have weighed in on whether carriers should be permitted to charge differently for individual slices of the network based on quality of service, latency or application type.

What is network slicing?

Network slicing allows an operator to partition a single physical 5G network into multiple virtual networks, each tuned for a specific use case. A slice configured for industrial automation, for instance, prioritises ultra-low latency and deterministic performance, while a slice for consumer mobile broadband optimises throughput. The capability is central to how operators worldwide plan to monetise 5G investments beyond flat-rate consumer data plans, particularly through enterprise contracts with automotive, healthcare and manufacturing customers.

What are stakeholders saying?

The submissions, processed through TRAI's consultation process, argue that allowing differentiated pricing or treatment for individual slices would effectively reintroduce the kind of paid prioritisation that India's 2016 net neutrality rules explicitly prohibited. Several respondents have reportedly called for any quality-of-service differentiation to remain purely technical — that is, driven by application requirements rather than commercial agreements.

Civil society organisations have historically been the strongest advocates for strict net neutrality enforcement in India. Their submissions to TRAI consultations have consistently opposed any mechanism that would allow operators to extract premium revenue from content providers or application developers in exchange for preferential treatment.

Why does this matter now?

India's 5G spectrum auction concluded in mid-2022, with Reliance Jio, Bharti Airtel and Vodafone Idea acquiring airwaves and subsequently launching commercial 5G services in stages. As 5G coverage expands and enterprise use cases move from pilots to commercial deployment, the question of how slices are sold — and to whom — has shifted from technical curiosity to commercial reality.

Network slicing depends on the 5G core architecture specified by 3GPP, the standards body that defines mobile network specifications. The feature requires both standalone 5G infrastructure and the orchestration capability to manage multiple virtual networks on shared physical resources. Indian operators have been deploying standalone 5G cores in selected circles, though coverage of the full slicing capability remains limited compared with consumer 5G broadband.

What regulatory context applies?

TRAI's existing net neutrality framework prohibits operators from charging content providers for preferential delivery of traffic. The 2016 rules also bar tariff differentiation based on the nature of content, website or application, with limited exceptions for specialised services such as voice over LTE, machine-to-machine communications, and certain enterprise offerings where technical parameters require distinct treatment.

The current consultation appears to test where enterprise-grade network slicing fits within those exceptions. Operators and vendors argue that slicing is fundamentally a technical tool, not a commercial preference scheme. Critics counter that any commercial transaction for guaranteed quality of service — regardless of how it is technically implemented — constitutes the kind of paid prioritisation the rules sought to prevent.

What happens next?

TRAI will review the stakeholder submissions and may issue recommendations or further consultation questions before finalising its position. The regulator's eventual framework will shape how Indian operators structure their 5G enterprise propositions, particularly for industrial customers evaluating private network and slice-based contracts.

The outcome will also signal whether India's net neutrality posture, established nearly a decade ago, retains its strict character in the 5G era or evolves to accommodate the technical and commercial realities of programmable networks.
