Changes planned for VoLTE

The telecom regulator has recommended suitable amendments in the Unified Licence to pave the way for interconnection to happen at the IP or `internet protocol' level between licenced operators.
If accepted by the government, users on newcomer Reliance Jio Infocomm's VoLTE-based 4G network will be able to call subscribers of other telcos who operate traditional `circuit switch' (CS) mobile networks, such as Bharti Airtel, Vodafone India or Idea Cellular, and vice-versa. Reliance Jio is tipped to commercially launch its 4G services in April.
This interconnection was one area of concern for sector experts as under current rules, largely only Jio-to-Jio calls would have been possible, which could also have limited the telco's hand in offering local and international roaming services.
Since “voice traffic is being carried over IP and traditional `CS' networks are gradually being phased out, there exists a need to facilitate interconnection at the IP level,“ which is why , “the Authority recommends the amendment to Clause 27.3 (Annexure) in the Unified Licence“ for this to happen, said the Telecom Regulatory Authority of India Trai) in its recommendations on `Interconnection over IP Interface' on Thursday.
The sector regulator has suggested that Clause 27.3 be reworded to broaden the scope of interconnection. “Interconnection between networks of different licencees or carrying CS traffic shall be as per national standards, and for (also) carrying IP-based traffic as per Telecom Engineering Centre (TEC) standards,“ says the amended Clause 27.3 of the unified li cence proposed by Trai.
Trai has recommended tweaking of Clause 27.3 in the absence of “an explicit clause relating to interconnection at the IP level in existing licences“.
