  1. TAKING A LOOK INSIDE Nicolas Damour Senior Manager for Business and Innovation Development, Sierra Wireless ndamour@sierrawireless.com oneM2Mwww.oneM2M.org

  2. Agenda • The Partnership Project • The Common Service Layer • The Technical Reports and Specifications • Use Cases and Requirements • Architecture and Information Modelling • Communication Protocols • Security • Device Management & Interworking with OMA/BBF • Interworking with 3GPP/3GPP2 and with AllJoyn

  3. The Partnership Project Over 200 member organizations in oneM2M

  4. Purpose, Work & Deliverables PurposeTo specify and promote anM2M Common Service Layer Work Six physical 1-week meetings per year About 5 conference calls per week between the meetings 200+ documents produced and discussed at each meeting 3800 docs in 2013 4200 docs in 2014 so far Deliverables Technical Reports and Technical Specifications

  13. Architecture Application Entity Provides application logic for the end-to-end M2M solutions Network Services Entity Provides services to the CSEs besides the pure data transport Node Logical equivalent of a physical (or possibly virtualized, especially on the server side) device ApplicationLayer AE AE AE Underlying Network Underlying Network NetworkLayer NSE NSE NSE NSE Application Service Node Middle Node Infrastructure Node

  14. Architecture Reference Point One or more interfaces - Mca, Mcn, Mcc and Mcc’ (between 2 service providers) Common Services Entity Provides the set of "service functions" that are common to the M2M environments Application Entity Provides application logic for the end-to-end M2M solutions Network Services Entity Provides services to the CSEs besides the pure data transport Node Logical equivalent of a physical (or possibly virtualized, especially on the server side) device ApplicationLayer AE AE AE Mca Mca Mca ServiceLayer CSE CSE CSE CSE Mcn Mcc Mcn Mcn Mcc Mcn Mcc’ Underlying Network Underlying Network NetworkLayer NSE NSE NSE NSE Application Service Node Middle Node Infrastructure Node Inf.

  15. Information Modelling Resource-based information model • Information is stored in the system as Resources • A given Resource can be identified with a Uniform Resource Identifier • A given Resource is of one of the defined Resource Types • The Resource Type determines the semantics of the information in the Resource • Resources can be Created, Read, Updated or Deleted to manipulate the information • Resources are organized in a tree-like structure and connected by links • Links either as the tree hierarchy or to another part or the tree

  16. Resource Types & Flows Defined resource types • The System (nodes, CSEs, AEs…): node, CSEBase, AE, mgmtObj… • M2M Service subscriptions: m2mServiceSubscriptionProfile… • Security: accessControlPolicy… • Entity groups and memberships: group, members… • Application data: container, contentInstance… • Information dispatch and flows: subscription, delivery, request, schedule… • Location services: locationPolicy… • Service charging & accounting: statsConfig, eventConfig, statsCollect… Defined communication schemes • Direct communication and subscriptions/notifications • Synchronous (blocking or non-blocking with regular polling) communications • Asynchronous (non-blocking, with callback) communications

  17. Communication Protocols Reuse IP-based existing protocols Service Layer Core Protocols TS-0004 CoAP BindingTS-0008 HTTP BindingTS-0009 MQTT BindingTS-0010 XML or JSON Content serialization HTTP Example REQUEST GET http://provider.net/home/temperature HTTP/1.1Host: provider.netFrom: //provider.net/CSE-1234/WeatherApp42X-M2M-RI: 56398096Accept: application/onem2m-resource+json RESPONSE HTTP/1.1 200 OKX-M2M-RI: 56398096Content-Type: application/onem2m-resource+jsonContent-Length: 107{"typeOfContent":"application/json","encoding":1, "content": "{'timestamp':1413405177000,'value':25.32}"}

  18. Security Reuse existing mechanisms SecuritySolutions TS-0003 EnrolmentProvisioning/Configuration of the M2M System (Devices, Applications…) Secure communicationsProtocols (TLS/DTLS), credentials and authentication (PSK/PKI/MAF) Access ControlDefined in accessControlPolicy resourcesWhich SUBJECT can perform which ACTIONSon which OBJECT under which CIRCUMSTANCES More detailsin the oneM2M webinar#3November 14th 2014
