1. Common Service Entities
Group Name: WG2
Source: Lionel Florit and Syed Z Hosain
Meeting Date:
Agenda Item: ARCH

2. Introduction
In TP#4, ARC255 we have outlined a generic functional view grouped in CSEs (Common Functional Entity).
The CSEs contain CSFs (Common Services Functions)
This contribution proposes candidate service layer CSFs for inclusion in R1 of the oneM2M architecture
Methodology
Describe call flows for 2 verticals: from device turn up to data collection
Derive the example of a generic call flow
Conclude with the CSFs needed

3. Example for AMI (Smart Grid)
AMI Head-End
Meter
NMS
Network Auth w AAA, Key Mgt
Route Discovery RPL
IP Add Assignment & NMS/HE IP resolution DHCP
CSMP Registration Message
Node “UP” in
