8.12 Group-based support

MOC groups may be used in many MOC applications. For example, a vehicle company owner
could manage the company vehicles in groups, e.g., track the locations of all the vehicles in the
group and send notification messages to all the vehicles in the group. An electricity company could
collect the metering data of all the MOC devices in a certain area at a certain time. A consumer
could query the different meters at his home when he is on a business trip.

Different MOC applications may have different MOC groups.
MOC applications may have static MOC groups which are pre-configured, for example the
consumer could pre-configure the MOC devices installed at his home into an MOC group. MOC
applications may also have dynamic groups which are grouped according to some on-demand
criteria, for example a vehicle company owner may request to communicate with all the vehicles in
a certain area when needed.

The MOC devices inside a group may directly connect to the network or indirectly connect to the
network.

The requirements for group-based support are the following:

1) MOC applications require the support of static and dynamic MOC groups.
2) MOC applications require the support of data transmission to/from one or all members in
an MOC group using group identifier.
3) MOC applications require the support of the group based QoS policy.

4) MOC applications require the support of group based traffic parameters.
5) MOC applications require the support of MOC group management, including
display/creation/modification/deletion of MOC groups and associated attributes and
display/addition/modification/deletion of MOC group members.

6) MOC applications are recommended to be able to send data per MOC group and apply data
prioritization according to member's data prioritization in the MOC group.

8.13 Quality of service

8.13.1 Application traffic control
The application traffic is not only generated by MOC devices, but also generated by MOC
applications.
MOC applications often cover a large number of MOC devices and gateways. In such scenarios,
from the viewpoint of applications, their QoS may be impacted by high application traffic.

From the viewpoint of the network, the QoS of MOC applications may be improved if the
application traffic is well managed.

MOC applications have the following requirements:
1) MOC applications require mechanisms for application traffic management, e.g., to limit the
maximum number of application transactions per second.
2) MOC applications require that access concentration into a single resource is avoided.

8.13.2 Data prioritization
The MOC mission-critical applications should be carefully managed. For example, emergency
notification of a fire incident must be delivered in a timely and reliable way to the appropriate
national disaster monitoring systems. In order to provide alarm notifications, the emergency data
are carried over the network.
