South Korean operators take lead with OneM2M platform
December 23, 2014
LG U+ and SK Telecom of Korea have both announced that they will make commercial deployments of IoT platforms based on OneM2M specifications in South Korea. Both platforms were demonstrated at this month’s OneM2M Showcase in Sophia Antipolis, France.
According to Kang Jong-oh, general manager at the platform development division of LG U+, the company added the OneM2M global standard to its existing IoT service infrastructure so as to target the international market. Kang said the company would support small- and medium-sized enterprises and start-ups in the IoT business.
SK Telecom’s development of its OneM2M-based open-source platform, Mobius, began in 2011 as a national project, together with the Korea Electronics Technology Institute and NTels. It plans to finalise the national project in the first quarter of 2015 and to open a platform on its commercial network later in the year.
"The announcements of these OneM2M-based platforms being made available commercially are the first such public statements and are proof of how important OneM2M is to operators as part of an IoT platform," said Richard Brennan, chairman of OneM2M's marketing group.
The LG U+ platform was demonstrated with LG Electronics, Modacom and Eluon. The Mobius platform was demonstrated by SK Telecom with Convida Wireless, Fraunhofer, Keti, NEC and NTels.
At the same event, NEC claimed to be the first company to test the OneM2M service layer standard in its Cloud City Operation Center (CCOC) system to enable M2M device interoperability in a live smart city programme.
NEC's use of the open OneM2M specification makes it possible to collect data from a diversity of sensors in a consistent and secure way for statistical and billing purposes and use robust data management models to enable cities to make informed day-to-day management decisions.
CCOC is based on the Fiware open source API-enabled platform and generic enabler, created by the EU-funded Future Internet project. The OneM2M stack has been added to this setup and connected to the IoT broker. It uses NEC's big data analysis platform for mass M2M data collection and processing.
The operation centre's dashboard enables key performance indicators (KPIs) to be quickly cross-referenced and visualised to provide a fast overview of the status of the city. For example, data sets on traffic, carbon monoxide, temperature and wind levels can be cross-referenced using the user interface so localised air quality alerts can be automatically issued.
Using OneM2M, sensors can be integrated using local area protocols, such as the IETF's (Internet Engineering Task Force) CoAP (constrained application protocol) or MQTT (message queue telemetry transport), which is currently being standardised by Oasis (the Organisation for the Advancement of Structured Information Standards). NEC is also developing an open linked data service layer to enable M2M sensor data to be easily connected and queried by third party businesses and used in social media and mobile apps.
"Testing our CCOC together with the OneM2M standard has already shown the value that the new international standard for M2M communications will bring for real-world computing systems,” said Jose Luis Mate, senior manager at NEC. “The flexibility of our product helped us to quickly integrate the new protocol stack. We can thus orchestrate a growing number of real world systems from various providers in a smart city and help create a brighter and smarter world."
