Fig. 1. High-level architecture of M2M system (adapted from [ 11 ])
Applications (DA), using M2M Device Service Capabilities Layer (DSCL), while
every M2M gateway runs M2M Gateway Applications (GA) using M2M Gate-
way Service Capabilities Layer (GSCL). Finally, M2M area network provides
connectivity based on personal or local area network technologies (e.g. Zigbee,
Bluetooth, WI-FI) between M2M devices and M2M gateways.
The network domain consists of M2M access network, M2M Network Appli-
cations (NA), M2M network management functions and M2M management func-
tions.M2M access network allows M2M devices and gateways to communicate
with the core network that enables interconnection with other networks, provides
IP connectivity or other connectivity options, service and control functions, and
roaming. M2M Network Service Capabilities Layer (NSCL) provides M2M func-
tions that are shared by different M2M NA that run the service logic and use the
M2M available service capabilities via open interfaces. M2M network manage-
ment functions encompass all the functions (e.g. provisioning, supervision, and
fault management) required to manage access and core networks, while M2M
management functions encompass all the functions (e.g. M2M service bootstrap
function), used to facilitate the bootstrapping of permanent M2M service layer
