            9.2     Requirements supported by existing NGN capabilities

            Based  on  the  service  requirements  in  clause  8,  this  clause  specifies  requirements  supported  by
            existing NGN capabilities for the support of MOC applications.

            9.2.1   Group management
            The  group  management  requirements  specified  in  clause  8.12  are  supported  by  the  existing
            capabilities of NGN [ITU-T Y.2201].

            9.2.2   Location management
            NGN  provides  the  location  management  capability  which  determines  and  reports  information
            regarding the location of users and devices within the NGN. The location management requirements
            specified in clause 8.11 are supported by the existing capabilities of NGNs [ITU-T Y.2201].

            9.2.3   Security
            An  NGN  provides  security  capabilities.  The  service  requirements  specified  in  clause  8.13  are
            supported by the existing capabilities of NGNs [ITU-T Y.2201] [ITU-T Y.2701].
            9.2.4   Group related communication modes

            Based  on  the  service  requirements  in  clause  8.12,  an  NGN  is  required  to  support  the  following
            communication  modes  for  MOC  groups  (with  MOC  devices  and  gateways  directly  or  indirectly
            connected to NGNs):

            –       any cast
            –       multicast
            –       broadcast.

            These requirements are supported by the existing capabilities of NGNs [ITU-T Y.2201].


            10      Capability requirements of an MOC device domain
            This  clause  identifies  the  capability  requirements  of  an  MOC  device  domain  for  the  support  of
            MOC applications.

            10.1    Application enablement

            Based on the requirements in clause 8.4, the following requirements apply to the MOC gateway and
            MOC device's capabilities:

            1)      MOC devices are recommended to support a set of abstracted operations.
            2)      MOC devices are recommended to support the implementation of service logic to provide
                    MOC capabilities.

            3)      MOC gateways can optionally support a set of abstracted operations on MOC devices.
            4)      MOC gateways can optionally support the implementation of service logic to provide MOC
                    capabilities.

            10.2    Mobility
            Based on the requirements in clause 8.1, the following requirements apply to the MOC gateway and
            device's capabilities:
            1)      MOC gateways and MOC devices are required to support enhanced mobility management
                    capabilities in order to support different levels of mobility.
