The document discusses oneM2M, an open standard that enables interoperability for the Internet of Things. OneM2M has over 200 member organizations and aims to provide common service functions and APIs to facilitate cross-domain interoperability. It serves as a horizontal platform and can interwork with various technologies. OneM2M's capabilities include device management, semantics, security features, and interworking with 3GPP cellular networks and other standards. The first commercial platform based on oneM2M was launched in Busan, Korea to support smart city services.

Goal: IoT Cross-Domain Interoperability
Without oneM2M With oneM2M
• Highly fragmented market with limited vendor-specific
applications
• Reinventing the wheel: Same services developed again
and again
• Each silo contains its own technologies without
interoperability
• End-to-end platform: common service capabilities
layer
• Interoperability at the level of communications
and data
• Seamless interaction between heterogeneous
applications and devices
• Standardized Horizontal Service Platform is key enabler for Operators
• It would stimulate large scale multi-vendor ecosystem with transparent product
features and benchmarks, encourages industry investment, and promotes new
business models.

oneM2M - 3GPP/CIoT Interworking:
Take advantages of operators’ network
capabilities to the maximum
• Integrating with the 3GPP Cellular IoT
(NB-IoT/eMTC) architecture to monetize
the network capabilities at the service layer.
• Hide the network layer complexity from
the IoT Applications and provide high level

oneM2M Proximal Interworking:
Flexible framework of interworking from
transparent, translucent to semantic
To make different technologies working smoothly together and
build a converged ecosystem
• Transparent Interworking: encapsulate the data model of one
technology into another (as a pipe)
• Translucent Interworking: data model structures are mapped, while
semantics/data types are not
• Semantic Interworking: mapping not only protocols, but also full data
models and semantics

Device Management -
Built on top of proven technologies
Designing Philosophy:
1. re-use existing technologies: OMA DM 1.X/2.0, LwM2M, BBF TR069/TR-181
2. hide the heterogeneity: oneM2M <mgmtObj> resources as the unified API for DM.

oneM2M Semantic Capabilities –
enrich the data intelligence
• Semantic Annotation • Semantic Discovery/ Query
› More to come: semantic validation, reasoning, mashup, rules, automation …
Example: Discover all resources representing devices that
measure temperature.

A perfect fit for Smart City IoT
Platform
Horizontal
platform for new
deployments
• Smart city is an incremental and participatory journey
• New deployments should, where possible, leverage a converged networks and an
horizontal service platform
• Open standards are key to avoid lock-in and master the total cost of ownership
Existing
deployments
• Do not disrupt existing “vertical deployment” but seek opportunities for an integration
path with an horizontal approach
• Build value through smash-ups and open data
Participatory and
innovative
approach
• Surveys
• Address needs for innovation through app development:
• APIs
• Access to, eventually semantically enriched, Open data (where feasible and
subject to privacy legislation/citizen consent)
Security and
(device)
management are
key
• Despite initial focus on IoT data, there is an increased interest in security and device
management (which go hand in hand).
• Need arises from security threat analysis conducted recently: e.g. ”Two researchers
analyzed Smart meters widely used in Spain and discovered that can be hacked by attackers to harm
the overall National power network.”, source:

Take-away
• Open standards to avoid lock-in to a platform or a cloud provider
– It is also a matter of national sovereignty
• Horizontal platform provides common service functions that enable multi-domains
– One investment/deployment serves multiple domains, do not re-invent the wheel
– Cross-domain service/application innovation with a common framework and consistent APIs
• Easy interworking/integration with existing & evolving deployments paves the way
to long term evolution and sustainable economy
– Do not disrupt existing “vertical deployment”, but evolve.
– Interworking with a rich set of proximal IoT technologies, embracing different ecosystems
– Take advantage of the operators’ network capabilities and existing management technologies
• Data sharing and semantic interoperability brings the real value
– data oriented RESTful API design
– semantic data annotation, discover and reasoning facilitates intelligent analytics and service mashups
– security protection at both channel and object level, with static and dynamic access control
