A Memorandum of Understanding (MoU) on technical knowledge sharing for establishing a nationwide Time Stamping & Time Synchronization network and traceability of time signal to UTC NPL time, was signed between Council of Scientific and Industrial Research -National Physical Laboratory (CSIRNPL) and Department of Telecommunications (DoT), Ministry of Communications. The nationwide time stamping & time synchronization network consisting of 22 numbers of Time Synchronization Centers (TSC’s) will be set up by DoT with technical assistance from CSIR-NPL. This network will provide synchronizing pulse in Indian Standard Time (IST) to all telecom & internet service providers in all the 22 LSA (Licensed Service Areas) in the country. The primary purpose of synchronizing the telecom network with IST time stamp is to enable the security agencies to overcome the difficulty in analyzing and correlating the cyber events in this era of greatly increasing network speed with advancement of telecom technology (2G to 3G to 4G to 5G etc.). The implementation of the project will also improve the telecom network efficiency by reducing packet loss due to reduced slips in better synchronized digital network. The time set on Indian telecom networks should be in IST zone to uniquely identify the user (subscriber) of network on tracing of the IP address and other parameters. Presently, Telecom Service Provider (TSP)/Internet Service Provider (ISP) are taking the reference time from different sources viz., GPS from GNSS. These sources do not have the traceability with IST. “Telecom Networks” need to be in IST time zone synchronized with CSIR-National Physical Laboratory (CSIRNPL) – the keeper of IST. The technologies developed by CSIR and its laboratories are of high value to Indian stakeholders, they be industry/government departments and ministries. After establishment & implementation of a PAN India time synchronization and time stamping across the Indian telecom network, all the network of the TSP/ISPs will be traceable with the IST, which will eliminate the problem of the time synchronization among the TSP/ISPs. This will lead to better efficiency of telecom network and reduce the Voice Over Internet Protocol (VOIP) call drop, improve the quality of service of the network, voice, video. The time standardization will help to curb cyber crimes and will also help to identify and correlate the various digital financial transactions. Accuracy of the time depends upon the distance between the TSC (reference source) and the location of the TSP/ISP centres. Therefore, stratum-1 time synchronization centre shall be established at all the 22 LSAs across the country.
