Telecommunications Standards Development Society, India (TSDSI)

1.Telecommunications Standards Development Society, India (TSDSI), a industry led not for profit organisation, is recognised by DoT as India's Telecom Standards Development Organization (TSDO). TSDSI came into existence on 7th January 2014 as an outcome of the Govt. of India's resolve vide the National Telecom Policy 2012 (NTP 2012) to setup a Telecom SDO in India.

2.TSDSI's objective is to contribute to next generation telecom standards and drive eco-system of IPR creation. TSDSI's 41 members include top telecom service providers, manufacturers, software solution providers, R&D organizations, academia, industry associations, PSUs and government department.

3. TSDSI Charter:

  • Develop standards to support new requirements based on research & innovation in the domain of telecommunications/ICT in India.
  • Distil new items of research for standardisation after analysing prevalent standards for applicability to the India centric requirements.
  • Take Indian requirements to global standards organizations;
  • Creating and Safe-guarding related IPRs;
  • Helping create standards based manufacturing expertise in the country;
  • Enforce a strictly methodical & transparent, open-to-all-members [Industry, Government, Academia] process while generating standards.
  • Providing guidance and leadership to developing countries (such as in South Asia, Africa, Middle East, etc.) for their telecommunications related standardization needs.

4. TSDSI Philosophy:

TSDSI follows a consensus based approach is followed towards standards development by involving all stake holders - Government, Academia and Industry. TSDSI follows the principles of Openness, Transparency, Fairness, Consensus and Due Process in conducting its activities. It maintains technology neutrality and provides a uniform playing field for all of its members.

5. Work Program of TSDSI

Technical standardization activities are carried out through Study Groups (SG) and Working Groups (WG). At present they have following Technical Groups:

5.1 SG1 Wireless Systems Study Group

This SG is instrumental in carrying out research activities related to wireless telecom systems which are the key-enablers for future communication systems. This group has 3 workgroups described below:

  • G1-WG1 (RNES)[Radio Network Evolution and Spectrum]: This work group presently deals with various RAT related research areas, most important of them being, mm-wave, device-t-device communication, cloud RAN, massive MIMO, and new waveform techniques.
  • G1-WG2 (CN)[Core Network]: This work group has (Network Function Virtualisation) NFV/ Software Defined Network (SDN) as its major thrust areas for research and standardization.
  • G1-WG3 (5G): This work group emphasizes on the end-to-end aspect of the 5G technologies.

5.2 SG2 Services Study Group

Services play a major factor in driving the CAPEX, OPEX and various other parameters of a network. Currently activities of this study group are being carried out in 2 WGs described below:

  • SG2-WG1 (M2M): This work group concentrates on M2M-IoT related activities and has identified 11 major verticals since last year where, there is a commendable work progress in some key areas.
  • SG2-WG2 (Indian Languages): This WG is responsible for the TSDSI standardization activities for Indic user interfaces and encoding methods and representation (fonts, rendering etc). The scope includes user terminals, mobile network equipment and applications.

5.3 SG3 (Optical Access and Transport)

It encompasses the development of standards on wireless & wireline backhaul, microwave, optical & packet based backhaul or transport network and Software Defined Network (SDN) infrastructures, NFV, systems, equipment, optical fiber cables, along with the related control plane, network management, performance monitoring & reporting, Synchronization, interfaces, multi layer optimization techniques, SDN network applications and testing aspects.

5.4 Energy Efficiency Group

The EE group is responsible for evaluating energy performance for telecommunication networks including access, user equipment, aggregation, core which includes underlying transport systems.

5.5 Security Group

The newly formed Security group has a broad scope of identification of essential requirements to ensure security assurance for cellular mobile telecom networks in India based on 3GPP SECAM SA3 work as related to fundamental approach, in consultation with various industry stakeholders. The details of various technical activities can be viewed on TSDSI website at

TSDSI has initiated a multi-year cooperation project with European Union focussing on the areas of 5G, NFV/SDN and Intelligent Transportation Systems (ITS).

6. Technical contributions to 3GPP with Indian IPR:

TSDSI members submitted a few technical contributions towards the development of 3GPP Narrowband IoT (Internet-of-Things) standard, backed by 4 patents filed by CEWIT and IIT Hyderabad (one granted and three pending). These proposals are being discussed by 3GPP for possible adoption in the NB-IoT standard.

7. TSDSI Alliances:

TSDSI has signed cooperation agreements with the following international SDOs:

  • Association of Radio Industries and Businesses (ARIB), Japan
  • Alliance for Telecommunications Industry Solutions (ATIS), USA
  • China Communications Standards Association (CCSA), China
  • Continua Health Alliance, USA (IoT in Health)
  • European Telecommunications Standards Institute (ETSI), Europe
  • Telecommunications Technology Association (TTA), Korea
  • Telecommunication Technology Committee (TTC), Japan

8.1 oneM2M Steering Committee Meeting (25th April 2016)

TSDSI is Partner Type I of oneM2M, one the leading forums driving M2M service layer standards. This entitles TSDSI member organizations to become Individual Members of oneM2M and contribute to standards development in M2M space. Currently, 6 TSDSI members have taken membership in this forum through TSDSI. A few of our members have already developed prototype oneM2M framework compliant platforms. Going forward, there will be a business opportunity for our members to offer oneM2M framework compliance testing and certification services in the global arena. oneM2M Steering Committee meeting was held on 25th April 2016 in New Delhi.

8.2 Global Standards Collaboration's 20th Meeting (GSC20) (26-27 April 2016)

TSDSI is a constituent SDO of Global Standards Collaboration (GSC) – a voluntary forum of the world's leading information and communication technologies standards organizations (SDOs). This forum meets once a year to deliberate upon strategic topics in the area of ICT based standardization that has a global impact. The 20th meeting of this forum was held in New Delhi on Apr 26-27, 2016. GSC20 was attended by 12 TSDOs, namely, ARIB and TTC from Japan, ATIS, IEC, IEEE, ISO, TIA from USA, CCSA from China, ETSI from Europe, ITU, a UN body from Switzerland, TTA from Korea and TSDSI. The opening ceremony of GSC20 was graced by Secretary, Telecom and Secretary, DeitY.

8.3 3GPP Meetings (PCG#36 and OP#35) (28-29 April 2016)

3GPP is an international standards body that has been standardizing cellular technologies like 3G (WCDMA/HSPA) and 4G (LTE), and is working towards the 5th generation cellular technologies of the future. TSDSI is one of the 7 Organizational Partners of 3GPP. This entitles TSDSI members to become Individual Members of 3GPP through TSDSI and take their IPR into the global arena. This also enables them to contribute in the development upcoming standards such as 5G. 13 TSDSI members have become 3GPP members through TSDSI. 3GPP's Project Coordination Group and Organizational Partners' meetings (3GPP – PCG#36 and 3GPP – OP#35) were held on 28th and 29th April 2016 respectively in New Delhi.
