Intellectual Property Rights
IPRs essential or potentially essential to the present document may have been declared to ETSI. The information
pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found
in ETSI SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in
respect of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web
server (http://ipr.etsi.org).
Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee
can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web
server) which are, or may be, or may become, essential to the present document.

1 Scope
The present document provides an evaluation of existing M2M-related Architecture work undertaken by the founding
partners of oneM2M, including: the Association of Radio Industries and Businesses (ARIB) and the
Telecommunication Technology Committee (TTC) of Japan; the Alliance for Telecommunications Industry Solutions
(ATIS) and the Telecommunications Industry Association (TIA) of the USA; the China Communications Standards
Association (CCSA); the European Telecommunications Standards Institute (ETSI); and the Telecommunications
Technology Association (TTA) of Korea. Common Functional Entities and Reference Points are identified, as well as
critical differences. New functionality will not be considered as part of this study.
The present document is intended to ensure a common understanding of existing M2M Architectural approaches, in
order to facilitate future normative work resulting in oneM2M Technical Specifications.
The present document has been prepared under the auspices of the oneM2M Technical Plenary, by the oneM2M
Architecture Working Group.
