Data Volume GPRS Downlink
The Data Volume GPRS Downlink field is a part of the ChangeOfCharCondition element in the List of Traffic Volumes.
It includes the number of octets transmitted in the downlink direction during the timeframe specified by the container. For
each new container, the counter is reset and does not accumulate. The data volume tabulated by the SGSN covers the
amount of user data transferred in the SNDCP PDUs (GSM) and GTP-U T-PDUs (WCDMA). Data volumes
retransmitted by RLC or LLC, due to poor radio link conditions, are not tabulated. The data counted includes the IP PDP
bearer protocols, i.e. IP or PPP.

Important:
In the CDRs, the data volume usage field is defined with a maximum size of 4 bytes. If the volume
triggers are disabled and the volume usage goes beyond 4GB, then the CDRs will not be generated and the data stats
will be reset to zero after the max usage.

Default Transaction/SMS Handling
This field indicates whether or not a CAMEL encountered default GPRS- or SMS-handling. This field is present only if
default call handling has been applied. Parameter is defined in HLR as part of CAMEL subscription information.
