This object indicates the number of service stop messages
by the CSG.
The following list summarizes the situations under which user
is disconnected from the service:
- When the CSG removes the user, by a RADIUS Accounting
(stop) message, the CSG sends the service stop message for
each service for which user had an active session.
- When the idle timer on the CSG expires, it will send service
stop for the category.
- If the QS sends service stop request message.
The CSG will report the usage and remaining quota.
