The Department of Telecommunication and Home Ministry are working together to put in place a mechanism to intercept and monitor 3G transactions services where it becomes necessary on grounds of national security. Allaying fears, the Home Minister, Mr Chidambaram said during his press conference that the idea is not to interrupt or delay 3G services but allow them to go forward even while the monitoring mechanisms are being put in place.Earlier, DoT had issued notices to a few telecom operators asking them to stop the GenNext mobile services- 3G, which includes video calling facility -asking them toput on hold the new services till they adhered to security norms for its legal interception. The DoT and central security agencies had convened a meeting of industry officials last month and asked them to stop roll-out of 3G services till they demonstrate interception facility. 3G mobile services mainly include voice call, video calls and data services.
