SGSN Address

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.
