2) If the network can handle data collected by MOC devices according to relevant data
categorization, MOC applications are required to manage these data accordingly.

9 Requirements of NGN capabilities

9.1 Requirements for extensions or additions to NGN capabilities
This clause identifies extensions or additions to NGN capabilities defined in [ITU-T Y.2201] for the
support of MOC applications.

9.1.1 Numbering, naming and addressing
NGN provides addressing and identification capabilities. The service requirements specified in
clause 8.10 are supported by the existing capabilities of NGN [ITU-T Y.2201] [ITU-T Y.2702].

Based on the service requirements in clause 8.12, NGN is required to support the following
additional numbering, naming and addressing requirements.

1) An NGN is required to provide group based addressing mechanisms for the support of
MOC applications according to the NGN provider's policy.

2) An NGN is required to support a static MOC grouping capability.
NOTE 1 – A static MOC group contains the members of the MOC devices and gateway which are pre-
configured.
3) An NGN is required to support a dynamic MOC grouping capability.

NOTE 2 – A dynamic MOC group may be generated upon request using specific criteria, such as location,
status of MOC devices and gateway, etc.
4) An NGN is required to support the MOC grouping capability in both cases of groups
constituted by MOC devices and gateway directly or indirectly connected to NGNs.
5) An NGN is required to map the MOC group identifier to network addresses of MOC
devices and gateways of a static MOC group.
6) An NGN is required to identify the list of MOC devices and gateways and their network
addresses matching the specified criteria for a dynamic MOC group.

9.1.2 Quality of service
The differentiated quality of service and data prioritization requirements, specified in clause 8.13
are supported by the existing capabilities of NGN [ITU-T Y.2201] [ITU-T Y.2221]. The following
subclauses identify the requirements for extensions to NGNs.
9.1.2.1 Per group QoS policy

Based on the service requirements in clause 8.12, the following additional requirements are placed
on NGNs:

1) An NGN is required to support a per group level QoS policy, in parallel with, or instead of,
a per device level QoS policy.

NOTE – Per group QoS policy parameters include, but are not limited to:
– packet transfer delay
– packet delay variation
– packet loss ratio
– packet error ratio.

9.1.2.2 Traffic control
NGNs provide processing and traffic management capabilities. The service requirements specified
in clause 8.7 are supported by the existing capabilities of NGN [ITU-T Y.2201].
