Overview
Important:
The system supports IMS authorization for IMS subscribers with Ty interface in cdma2000 networks.
IMS authorization support is a license enabled feature and you must obtain and install a license key to enable it.
IMS service provides wide application support for transport of voice, video, and data independent of the access support.
The roaming IMS subscriber in cdma2000 networks requires specific interface support for service access in this
network.

Apart from other functionality sufficient, uninterrupted, consistent, and seamless user experience is expected by a
subscriber during an application session. It is also important that the subscriber gets charged only for the amount of
resources consumed by the particular IMS application used.
subscriber during an application session. It is also important that the subscriber gets charged only for the amount of
resources consumed by the particular IMS application used.
In view of required flow bandwidth and QoS, the ASR 5000 Series Platforms provide enhanced support for use of
Service Based Local Policy (SBLP) to provision and control the resources used by the IMS subscriber. SBLP is based
on the dynamic parameters such as the media/traffic flows for data transport, network conditions and static parameters,
such as subscriber configuration and category. It also provides Flow based Charging (FBC) mechanism to charge the
subscriber dynamically based on content usage.
