"Compliance report from Telecom Service Providers, except Tata Teleservices Ltd, is awaited. TSPs are requested to submit compliance for the same," DoT said in a circular dated December 30, 2013.
Government had amended licence conditions of telecom service providers in May 2011 and asked them to provide location details of users as part of call data records.
According to the target set by DoT, law enforcement agencies should be able to track 30 per cent of mobile users in urban areas within 50 metres of the location pointed out by a telecom operator.
DoT has repeatedly asked for compliance reports but telecom companies have not submitted them.
In August, DoT had again asked for the report but even after four months the operators, except TTSL, are yet to submit their report.
