This Recommendation specifies the interworking capabilities of the machine to machine (M2M) service layer between application service node/infrastructure node/middle node (ASN/IN/MN) common services entities (CSEs) and lightweight machine to machine (LWM2M) endpoints using the architecture identified in Annex VI of oneM2M TS-0001 [ITU-T Y.4500.1] for the following interworking scenarios: ?C Interworking for transparent transport of encoded LWM2M objects and commands in content sharing resources between LWM2M endpoints and M2M applications. ?C Interworking with full mapping of LWM2M objects in LWM2M endpoints to semantically enabled content sharing resources that are utilized by M2M applications. NOTE ?C The present Recommendation limits content sharing resources to <container> and <contentInstance> resources. The Recommendation contains oneM2M Release 2 specification oneM2M LWM2M Interworking V2.0.0 and is equivalent to standards of oneM2M partners including ARIB@ ATIS [b-ATIS.oneM2M.TS0014]@ CCSA [b-CCSA M2M-TS-0014]@ ETSI [b-ETSI TS 118 114]@ TIA@ TSDSI [b-TSDSI STD T1.oneM2M TS-0014]@ TTA [b-TTAT.MM-TS.0014] and TTC [b-TTC TS-M2M-0014].
