Reference excerpt

oneM2M is a global partnership project founded in 2012 and constituted by 8 of the world's leading ICT standards development organizations, notably: ARIB (Japan), ATIS (United States), CCSA (China), ETSI (Europe), TIA (USA), TSDSI (India), TTA (Korea) and TTC (Japan). 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 standardised specifications produced by oneM2M enable an Eco-System to support a wide range of applications and services such as smart cities, smart grids, connected car, home automation, public safety, and health.

Organisation Membership A oneM2M Member is any legal entity which has an interest in the development and/or implementation of oneM2M Technical Specifications and Technical Reports. oneM2M Members must be members of a oneM2M Partner:

ARIB – Japan ATIS – U.S. CCSA – China ETSI – Europe TIA – U.S. TSDSI – India TTA – Korea TTC – Japan. Members can attend and participate in the oneM2M Technical Plenary meetings and its Working Groups where they have one vote each. They can also attend the oneM2M Steering Committee meetings but do not have voting rights. oneM2M currently has more than 200 participating partners and members, among the main actors of the ICT industry like for instance Nokia, AT&T, BT Group, Samsung, Telecom Italia, IBM, Deutsche Telekom, SK Telecom, Cisco, Orange, Qualcomm, InterDigital, Intel, Huawei, LG Uplus, KDDI, etc. oneM2M actively encourages industry associations and forums with specific application requirements to participate in oneM2M, in order to ensure that the solutions developed support their specific needs.

oneM2M Standard It is an open standard with a transparent development process and open access to all deliverables.

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 (CSF’s) provide proper:

Identification of users and applications Authentication and authorization 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 (AEs) at the device (ADN, MN) and the Infrastructure Platform (IN) are separated by the oneM2M APIs from the actual oneM2M Common Service functions (CSFs) 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 (CSFs) 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 (Modbus, CAN-Bus, OPC-UA gateways, etc.) On the infrastructure (Platform) the separation by APIs between oneM2M CSFs and applications, enables a separation between “low level” tasks in context of connectivity over wide area networks (Device Management, scheduling of data transmission, enrolment of security functions and credentials, revocation of faulty device applications), 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 (AEs) reside within individual device and sensor applications. They provide a standardized interface to manage and interact with applications. Common Services Entities (CSEs) play a similar role in the services layer which resides between the applications layer and 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 (SDOs), notably:

Worked examples

Example 1 — a first encounter with OneM2M

Start with the simplest possible case. Write down what OneM2M claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to OneM2M before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about OneM2M ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of OneM2M

In research: OneM2M appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses OneM2M in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: OneM2M is common in secondary-school and first-year university syllabi. It links to neighbouring topics International business organizations, Telecommunications companies, Telecommunications companies established in 2012, so understanding it makes those chapters shorter.
In everyday life: Look for OneM2M outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
