leading operators Aircel, Vodafone and Idea are using call drop masking technology or RlT incorrectly in Mumbai, telecom regulator Trai said on Tuesday.
“Most of the operators have focused on network improvement. However, usage of RlT (ie time-out period for releasing the call ) by Aircel, Vodafone and Idea is incorrect and needs to be addressed immediately,” the Telecom Regulatory Authority of India said in its Mumbai drive test report.
According to sources, telecom operators are using RlT to mask call drops. With the help of this technology, a call remains connected even if a consumer moves to poor network coverage area for which he is billed.
However, industry body COAI has denied allegation stating that the so called ‘call drop masking technology’, is actually a network parameter called, Radio link Time Out (RlT) feature, which is a part of the GSM standards and is used globally.
