List of Traffic Data Volumes
A list of the changes that occurred in the charging conditions for this PDP context.
The list will include one or more containers each including the following fields:
QoS negotiated: Quality of service (QoS) has been negotiated. The initial and final corresponding data values are
listed. This is only added for the first container and the container after a QoS change.
listed. This is only added for the first container and the container after a QoS change.
Uplink volume: The number of octets (uncompressed) received from the MS. The initial and final corresponding
data values are listed.
data values are listed.
Downlink volume: The number of octets (uncompressed) transmitted to the MS.The initial and final
corresponding data values are listed.
corresponding data values are listed.
Change Condition: Identifies the reason that the container was closed such as tariff time change, QoS change, or
closing of the CDR.
closing of the CDR.
Change Time: A time stamp identifying the time at which the volume container or the CDR closed.
User Location Information: Identifies the location of the user known at the time when conatiner is created.
For GPRS, data volumes are in octets above the GTP layer and are separated for uplink and downlink traffic. In UMTS,
data volumes are in octets above the GTP-U layer and are separated for uplink and downlink traffic.
