This object when set to 'true' enables the trigger for PLMN
change for postpaid users using this charging profile. When
enabled, the current PLMN-ID is always written into the
service-record. If none is received in the PDP create/update
request, a value of zero is written into the service-record.
This object can be set to 'true' only when the object
cgprsCgServiceRecordIncludePlmn is 'true'.
When a PLMN-ID change is received, the G-CDR is closed.
A new service-record is generated and the new PLMN-ID is
written into the new service-record.
