PDP context. This field is missing if the address is static, that
is, part of the PDP context subscription.
|
List of Traffic Data Volumes
|
M
|
This list includes
one or more Traffic Data Volume containers. The number of containers
is configurable with a maximum of 4 for WLAN-CDRs.
|
Change of Charging Condition
|
M
|
One traffic data volume
container contains a list of change of charging conditions:
Data Volume Uplink
Data Volume Downlink

The QoS values may
only be included in the first container. In later containers, the
presence depends on what was changed.
|
QoS Negotiated
|
O
|
This field indicates
that the applied QoS is accepted by the network. This field is compliant
with 3GPP standards.
|
GPRS Uplink
Data Volume
|
M
|
This field includes
the number of octets transmitted during the use of the packet data
services in the uplink direction.
Note that a maximum
of 2^32 bytes can be counted in this field. A volume trigger
should be defined for this value to avoid an overflow, if not already
done for a smaller amount of traffic.
|
GPRS Downlink Data
Volume
|
M
|
This field includes
the number of octets transmitted during the use of the packet data
services in the downlink direction.
Note that a maximum
of 2^32 bytes can be counted in this field. A volume trigger
should be defined for this value to avoid an overflow, if not already
done for a smaller amount of traffic.
|
Change Condition
|
M
|
This field defines
the reason for closing the container, such as tariff time change,
QoS change, or closing of the CDR. Values according to 3GPP TS 32.298
are:
qoSChange =
0
tariffTime = 1
recordClosure = 2
|
Change Time
|
M
|
A time stamp that
defines the moment when the volume container or the CDR is closed.
|
Record Opening Time
|
M
|
This field contains
the time stamp of when the PDP context is activated in the PDG or
when a subsequent record is opened after a partial record.
The timestamp is determined
based on the internal timer which has an accuracy of 10ms. Depending
on the configured mechanism (ceiling, floor, or round-off) this
field is translated to only show full seconds.
|
Duration
|
M
|
This field contains
the duration in seconds of the PDP contexts with the range of 0
to 4294967295 (2^32-1). It is the duration from Record
Opening Time to record closure. For partial records, this is the
duration of the individual partial record and not the cumulative duration.
|
Cause for Record Closing
|
M
|
This field shows the
reason for the release of the CDR. The values are:
|
Diagnostics
|
O
|
This field is included
in the CDR when the PDP context is released and when the option gtpp-attribute diagnostics is
configured.
|
gsm0408Cause
|
M
|
This cause is used
in the Diagnostics field and contains one of the following values:
- 36: If the PDP context
is terminated gracefully
- 40: AAA Server disconnect
- 26: If the PDG sends
delete PDP context request for any other reason
|
Record Sequence Number
|
O
|
A running sequence
number with range 1 to 4294967295 that links partial records generated
by the PDG for a specific PDP context (characterized with the same
Charging ID and PDG address pair). This field is not present if
the first record is also the final record.
|
Node ID
|
O
|
This field contains
an identifier string for the node that generated the CDR. The NodeID
field is a printable string of the ndddSTRING format:n: the first digit is
the sessmgr restart counter having a value between 0 and 7.
ddd: The number of the
sessmgr instance generating the CDR.
STRING: A configured
Node-ID-Suffix string of 1 to 16 characters. Defined with the gtpp attribute node-id command.
|
recordExtensions
|
O
|
|
Local Record Sequence Number
|
O
|
For each Node ID,
this number with range 1 to 4294967295, is allocated sequentially
for each CDR. With the Node ID, it uniquely identifies a CDR.
For WLAN-CDRs, this
field is only included when the option gtpp attribute local-record-sequence number is
configured.
|
APN Selection Mode
|
O
|
An index that shows
how the APN is selected:0 = MS or network
provided APN, subscribed verified
1 = MS provided
APN, subscription not verified
2 = Network
provided APN, subscription not verified
|
Served MSISDN
|
O
|
This field tracks
the Mobile Station (MS) ISDN number (MSISDN) of the subscriber,
which is sent by the AAA server.
|
Charging Characteristics
|
M
|
Lists the charging
characteristics applied to the PDP context. The PDG can accept charging
characteristics from the AAA server or use its own configured value.
PDG-configured charging characteristics are specified as part of
the PDG Service and are applied for WLAN-CDRs to subscriber PDP
contexts through APN templates.
|
Charging Characteristics Selection
Mode
|
O
|
Lists the charging
characteristic type that the PDG applied to the CDR. The values
for this field are defined in 3GPP TS 32.298:
AAASupplied (0): The PDG
is using the charging characteristics supplied by the AAA Server.
homeDefault (3): PDG
configured charging characteristics for home subscribers are used.
roamingDefault (4):
PDG configured charging characteristics for roaming subscribers are
used.
visitingDefault (5):
PDG configured charging characteristics for visiting subscribers are
used.
|

|
O
|
This field shows the
Radio Access Technology (RAT) type currently used by the Mobile
Station. This field is present in the CDR if provided by WLAN. RAT
Type values:

1 = UTRAN
2 = GERAN
3 = WLAN
