OneM2M


oneM2M is a global partnership project founded in 2012 and constituted by 8 of the world's leading ICT standards development organizations, notably: ARIB, ATIS, CCSA, ETSI, TIA, TSDSI, TTA and TTC. The goal of the organization is to create a global technical standard for interoperability concerning the architecture, API specifications, security and enrolment solutions for Machine-to-Machine and IoT technologies based on requirements contributed by its members.
The produced standardised specifications enables an Eco-System to support a wide range of applications and services such as smart cities, smart grid, connected car, home automation, public safety, and health.
oneM2M technology is removing fragmentation in the IoT world. Because it is independent of the connectivity- or protocol technology that is used for transport, it is designed to be a long term solution for IoT deployment.

oneM2M Standard

It is an open standard with a transparent development process & an open access to all deliverables. All the specifications, even the drafts are available at http://onem2m.org/technical/published-drafts

ITU-T Transposition

The oneM2M standards are internationally recognized and transposed by ITU-T under the Y.4500 series

Technical overview

Service Layer for multivendor interoperability.
The architecture standardised by oneM2M defines an IoT Service Layer, i.e. a vendor-independent software Middleware between processing and communication hardware and IoT applications providing a set of functions commonly needed by IoT applications.
The oneM2M Service Layer provides use case-independent functions.
• oneM2M Common Service layer Functions provide proper:
• Identification of users and applications
• Authentication and authorisation of users and applications
• End-to-end data encryption
• Remote provisioning and service activation
• Device management
• Connectivity setup and data transmission scheduling
• Data aggregation, buffering in case of missing connectivity and synchronisation upon connectivity re-establishment
• Group management and application and data discovery functions
The functions listed above provided by the oneM2M common service layer, are exposed and controlled via globally standardized vendor-independent and uniform APIs, towards the IoT applications.
IoT applications or more generically “Application Entities” AE’s are generic terms for applications executed in so-called Application Dedicated Nodes ADNs or Middle Nodes MNs and at the Infrastructure Node IN.
Applications at the device and the Infrastructure Platform are separated by the oneM2M APIs from the actual oneM2M Common Service functions like the ones listed above.
Details and specifics of the underlying - connectivity technologies, transport protocols and data serialisation formats are not exposed to the application developer. This avoids the necessity of detailed expertise in used connectivity technologies, and hence allows the application developer to focus on the actual customer IoT application.
Interactions between oneM2M Common Service Functions and the application are solely based on the oneM2M globally standardised, vendor independent, uniform APIs towards the applications.
For an application developer, oneM2M based technology appears like an operating system, which takes over common basic functions in context of connectivity and hardware as listed above. Hence the IoT Service Layer specified by oneM2M can be seen in a similar way as a mobile operating system within the smart phone eco system.
Due to this separation, application developers can focus on developing the actual IoT application for the Device e.g focusing on:
• Measuring physical parameters, pre-processing of data, controlling attached hardware or Interworking with other technologies
On the infrastructure the separation by APIs between oneM2M CSFs and applications, enables a separation between “low level” tasks in context of connectivity over wide area networks, and actual cloud and IoT application platforms like:
• Data analytics, rule engines, presentation of data, user interfaces, etc.
Compared to IoT devices being connected to IoT Platforms without oneM2M, the separation between Applications and oneM2M CSFs, enables the device to become independent from the actual cloud respective IoT Application Platform provider. Beneficially the oneM2M CSFs will become part of the communication chipset to achieve coverage in a wide range of devices.

Architecture Overview

oneM2M standard employs a simple horizontal, platform architecture that fits within a three layer model comprising applications, services and networks. In the first of these layers, Application Entities reside within individual device and sensor applications. They provide a standardized interface to manage and interact with applications. Common Services Entities play a similar role in the services layer which resides between the applications layer and the in the network layer. The network layer ensures that devices and sensors and applications are able to function in a network-agnostic manner.

History

oneM2M was formed in July 2012 and consists of eight of the world's preeminent standards development organizations, notably:
These SDOs were joined by six industry fora, consortia or standards bodies.
oneM2M began some of the earliest work on standardization of a common platform for internet of things systems. In 2018, S. Korea's TTA reported its cooperative efforts with the ITU to bridge standardization gaps by transposing the oneM2M standard to an ITU standard.

Partners

oneM2M currently have more than 200 participating partners and members consisting of Alcatel-Lucent, AT&T, BT Group, Adobe, Ericsson, Deutsche Telekom, IBM, Cisco, Sierra Wireless, InterDigital, Intel, Samsung, LG Uplus and Telefonica.

Regional Developments

South Korea is one of the leading markets for solutions based on the oneM2M standard. South Korea’s national IoT Master Plan makes explicit reference to oneM2M as a strategic enabler for IoT applications and companies developing IoT solutions. The city of Busan is implementing an open platform based on oneM2M to support a smart-city eco-system of industry-university associations.
In Europe, HP Enterprise has reported commercial success in the enterprise and smart cities sectors.
Within the UK, a public-private partnership is using InterDigital's oneM2MTM standards-based IoT platform developed by InterDigital to support a large-scale, intelligent transport systems trial. The trial, oneTRANSPORT, is part funded by InnovateUK and involves 11 public and private sector organizations with an operational footprint that covers four contiguous counties in England. The aim of the trial is to demonstrate several journey planning, transport-event and incident management applications.
Bordeaux-Métropole has also opted for the “city as a platform” path and started with the deployment of an IoT platform based on oneM2M to support all new ICT applications. There are considerable advantages to this approach when it comes to the ownership of city data and the responsible management of citizen data in line with Europe’s General Data Protection Regulation. It enables the reuse of data beyond originally intended purposes and assists in avoiding vendor lock-in, moving away from data silos and laying the foundation for new cross-domain ICT applications. It became clear that deploying IoT in silos would limit the ability to scale smart city solutions. It also became clear that IoT platforms based on open standards are best capable of supporting a diverse range of IoT applications, the sharing of associated data and avoid lock-in to technology providers.

Standardization Releases

Release 1 was issued in February 2015. It provided a standardized, general-purpose horizontal architecture for IoT platform operators and service providers to deploy IoT solutions.
Release 2 was issued in August 2016. It added an interworking framework enabling each service provider to support more types of devices on their IoT platform. Release 2 also provided enhanced end-to-end security features.
Release 3 was issued in December 2018. It added a complementary set of oneM2M value-added services to complement IoT features in 3GPP standards. These features help to mitigate network congestion and security issues in mobile operator networks, creating a pathway to scalable IoT deployments.

Developer Resources

In addition to standards development activities, members participating in the oneM2M Partnership Project provide a portfolio of resources to assist potential users and developers. These include the following:
