oneM2M Overview

The oneM2M Global Organization creates Technical Specifications (TSs) to ensure that Machine-to-Machine (M2M) Communications can effectively operate on a Worldwide scale.

Seven (7) of the World's leading Information and Communications Technology (ICT) Standards Development Organizations (SDOs) launched in July 2012 a new Global Organization to ensure the most efficient Deployment of Machine-to-Machine (M2M) Communications Systems.

The new organization, called oneM2M, develops specifications to ensure the Global Functionality of M2M—allowing a range of Industries to effectively take advantage of the benefits of this emerging Technology.

The seven (7) majors ICT SDO founders of oneM2M are:

  • The European Telecommunications Standards Institute (ETSI) , Europe

  • The Association of Radio Industries and Businesses (ARIB), Japan

  • The Telecommunication Technology Committee (TTC), Japan

  • The Alliance for Telecommunications Industry Solutions (ATIS), USA

  • The Telecommunications Industry Association (TIA), USA

  • The China Communications Standards Association (CCSA), China

  • The Telecommunications Technology Association (TTA), Korea                                   

The members of the organization are devoted to developing Technical Specifications and Reports to ensure M2M Devices can successfully communicate on a  Global scale.

 

The oneM2M Standardization work is split in five (5) WG:

  • WG1: Requirements

  • WG2: Architecture

  • WG3: Protocols

  • WG4: Security

  • WG5: Requirements and Domain Models (former MAS-Management, Abstraction and Semantics)

The Test Specifications cover different testing aspects such as interoperability, interworking, Conformance, Performance and Security for different Protocols and Network elements.

oneM2M supported IoT Use Cases (UCs) - SAREF (Smart Applications REFerence) Ontology

oneM2M supports IoT Use Cases (UCs) Smart M2M SAREF (Smart Appliances REFerence) Ontology. Initially, SAREF V1 was common to three (3) Domains, namely:

  1. Energy,

  2. Environment 

  3. Buildings 

The first core of SAREF (mapped into three (3) Applications’ Domains) has been improved to SAREF V2, thento SAREF V3 to enable mapping of SAREF with more Smart Applications domains such as:

       4. Smart City,

       5. Smart Industry and Manufacturing

       6. Smart Agriculture and Food,

       7. Automotive

       8. eHealth and Ageing-Well,

       9. Wearables

       10. Smart Water,

       11. Smart Lift…)

Like this SAREF became Smart Applications REFerence Ontology (core SAREF) with its domain mapping extensions.

oneM2M Layered Architecure Model

oneM2M Layered Model comprises three (3) layers:

  • the Application Layer,

  • the Common Services Layer

  • the underlying Network Services Layer.

Application Entity (AE): The Application Entity is an Entity in the Application Layer that implements an M2M Application Service Logic. Each Application Service Logic can be resident in a number of M2M Nodes and/or more than once on a Single M2M Node. Each execution instance of an Application Service Logic is termed an "Application Entity" (AE) and is identified with a unique AE-ID.

Examples of the AEs include an instance of a fleet tracking application, a remote blood sugar measuring application, a power metering application or a pump controlling application.

Common Services Entity (CSE): A Common Services Entity represents an Instantiation of a Set of "Common Service Functions" of the oneM2M Service Layer. A CSE is actually the Entity that contains the collection of oneM2M-specified Common Service Functions that AEs are able to use. Such Service Functions are exposed to other Entities through the Mca (exposure to AEs) and Mcc (exposure to other CSEs) Reference Points.

Reference Point Mcn is used for accessing services provided by the underlying Network Service Entities (NSE) such as waking up a sleeping device. Each CSE is identified with a unique CSE-ID.

Examples of service functions offered by the CSE include: data storage & sharing with access control and authorization, event detection and notification, group communication, scheduling of data exchanges, device management, and location services.

Network Services Entity (NSE): A Network Services Entity provides Services from the underlying Network to the CSEs.

oneM2M Common Service functions (CSFs) (applied to all IoT Domains: SAREF IoT UCs (Use Cases))

oneM2M's horizontal Architecture provides a Common Framework for IoT. oneM2M has identified a Set of Common Functionnalities, that are applicable to all the IoT Domains (SAREF). Think of these functions as a large Toolbox with special tools to solve a number of IoT problems across many different domains. Very much like a screw driver can be used to fasten screws in a car as well as in a plane, the oneM2M CSFs are applicable to different IoT Use Cases (UCs)/Domains in different Industry Domains.

In its first phase, oneM2M went through a large number of IoT Use Cases (UCs) and identified a Set of Common Requirements which resulted in the Design of this Set of Tools termed Common Service Functions (CSFs).

Furthermore, oneM2M has standardized how these Functions are being executed, i.e. is has defined uniform APIs to access these functions. Figure 5.3.1-1 shows a grouping of these functions into a few different scopes.

The Services above reside within a CSE (Common Service Entity) and are referred to as Common Services Functions (CSFs). The CSFs provide Services to the AEs via the Mca Reference Point and to other CSEs via the Mcc Reference Point.

oneM2M pre-integrated with 5G (3GPP) Specifications for cIoT

oneM2M baseline Architecture supports interworking with 3GPP and 3GPP Cellular Internet of Things (CIoT) Features such as IP and non-IP Data Control Plane Data Delivery. The oneM2M system may leverage the IoT related Features and Services that 3GPP added in Releases 10 through 15.  Features and Services may be accessed by an ADN-AE, MN-CSE, or an ASN-CSE that is hosted on a UE and an IN-CSE that is able to access services that are exposed by a MNO.

The “3GPP Trust Domain” in Figure 5.2-1 captures the Functional entities that shall be part of the 3GPP Domain (the Network). Although the Figure 5.2-1 shows that the IN-CSE and IN-AE are outside of the 3GPP Domain, the IN-CSE may be part of the Operator domain (Fig. 4.2-1b).
