Charging ID
5
M
This field is a charging identifier, which can be
used together with the GGSN address to identify
all records produced in the GGSN involved in a
single PDP context. The Charging ID is
generated by the GGSN at PDP context
activation and is transferred to the context
requesting SGSN. At an inter-SGSN routing area
update the charging ID is transferred to the new
SGSN as part of each active PDP context.
The possible values for the charging ID, which
are defined in TS 29.060 are 1-4,294,967,295
and those values are encapsulated in following
scheme in the CDR-field:
1 - 127 850101-85017F

SGSN Address
6
M
This field contains one or several SGSN IP
addresses.
For an S-CDR, the SGSN address contains the
control plane or user plane address of the current
SGSN serving the PDP context.
For a G-CDR and eG-CDR, in addition to the
current SGSN being used, the field may contain
additional SGSN addresses where the PDP
context was located before and where it has
moved away using the Inter-SGSN Routing Area
Update Procedure. The maximum number of
addresses in the list is 5.
