Appendix I

Comparison between the capabilities of the ITU-T M2M service layer
and common services functions of oneM2M

(This appendix does not form an integral part of this Recommendation.)

This appendix provides comparison between the capabilities of the ITU-T M2M service layer and
CSFs of oneM2M. oneM2M defines CSE as Figure I.1 in [b-oneM2M-TS-0001].

Figure I.1 – oneM2M common services functions

Figure I.2 shows the summary of comparison between the capabilities of the ITU-T M2M service
layer and the CSFs of oneM2M.

For example, some functions of communication management/delivery handling and device
management in CSFs of oneM2M is covered by communication management capability of the
ITU-T M2M service layer.

The main differences between them are that oneM2M CSF does not dealing with the application-
specific support and ITU-T M2M service layer does not dealing with the subscription and notification.
