This MIB module manages the service-aware feature of
Gateway GPRS Support Node (GGSN).
This MIB is an enhancement of the CISCO-GGSN-MIB.
There needs to be a tight coupling between GGSN and CSG
in order to realize the enhanced GGSN, which is capable
of categorizing traffic flowing within a PDP context to
different services.
An enhanced version of Diameter Credit Control
Application (DCCA) will be used for implementing
real-time credit control of end users in the IPS
framework. The GGSN will act as DCCA client and will
interact with DCCA server for quota negotiation and
usage reporting.
The credit control request (CCR) message is used between
DCCA-Client (DCCA-C) and DCCA-Server to request credit
authorization for a given service. The credit control
request has one mandatory AVP (Attribute Value Pair)
called CCR. For a session based credit control
several interrogation required, the first, intermediate
and final. The first interrogation must be sent
before the DCCA-C allows any service event to the
user, CCR type is set to INITIAL in this case. When all
the granted service units for one unit type are spent
by the end user or the validity time is expired
the DCCA-C must send a new credit control (CC) request
to CC server, this is the intermediate interrogation
and the CCR type AVP is set to the value UPDATE.
When the end user terminates a service session the
DCCA-C must send a final CCR request message to the
CC server. The CCR type AVP is set to the FINAL
or TERMINATION_REQUSET.
CSG will be responsible for categorizing the traffic,
quota management activities and usage reporting
functions. GGSN will act as a quota server for CSG.
A proprietary interface based on GTP' will be used
between GGSN and CSG.

ication is generated when CSG state goes
up. This notification is deprecated and replaced by
cGgsnSACsgR100StateUpNotif.
cGgsnSACsgStateDownNotif
.1.3.6.1.4.1.9.9.497.2.0.2
ication is generated when CSG state goes
down. This notification is deprecated and replaced
by cGgsnSACsgR100StateDownNotif.
cGgsnSADccaEndUsrServDeniedNotif
.1.3.6.1.4.1.9.9.497.2.0.3
ication is generated when the credit-
control server denies the service request due to
service restrictions. On reception of this notif
on category level, the CLCI-C shall discard all future
user traffic for that category on that PDP context and
not attempt to ask for more quotas during the same PDP
context.
cGgsnSADccaCreditLimReachedNotif
.1.3.6.1.4.1.9.9.497.2.0.4
ication is generated when the credit limit
is reached. The credit-control server denies the service
request since the end user's account could not cover the
requested service. Client shall behave exactly as with
cGgsnSADccaEndUsrServDeniedNotif.
cGgsnSADccaUserUnknownNotif
.1.3.6.1.4.1.9.9.497.2.0.5
ication is generated when the specified
end user is unknown in the credit-control server.
Such permanent failures cause the client to enter
the Idle state. The client shall reject or terminate the
PDP context depending on whether the result code was
received in a CCA (Initial) or CCA (Update).
cGgsnSADccaRatingFailed
.1.3.6.1.4.1.9.9.497.2.0.6
ication is generated when the credit-control
server cannot rate the service request, due to insufficient
rating input, incorrect AVP combination or due to an AVP or
an AVP value that is not recognized or supported in the
rating.
cGgsnSADccaAuthRejectedNotif
.1.3.6.1.4.1.9.9.497.2.0.7
ication is generated when credit-control
server failed in authorization of end user. The PDP
context is deleted and category is blacklisted.
cGgsnSACsgR100StateUpNotif
.1.3.6.1.4.1.9.9.497.2.0.8
ication is generated when CSG state goes
up. The objects in the varbind list represents -
