1. The change condition is based on the current ULI type and not on new ULI. i.e if the ULI
type is ECGI during CSRequest and while changing the ULI, whatever be the ULI type in
MBRequest, the “changeCondition” should be ECGI change.
MBRequest, the “changeCondition” should be ECGI change.
2. If the initial ULI has one or more ULI Types (i.e. ECGI, TAI, RAI, CGI), then the change
condition the priority will be as follows:
•
CGI-SAI Change
•
RAI Change
•
TAI Change
•
ECGI Change
3. If the current ULI type is not present (optional) in CSRequest the change condition is
based on the new ULI contents. That is, if new ULI has ECGI, then it will be considered
as ECGI change.
as ECGI change.
4. The ULI in main CDR part indicates the ULI at the time of record opening time. i.e. If
CSReq comes with ULI U1 and then the ULI is changed to U2, U3 and if a CDR is
generated the main ULI in CDR contains ULI as U1, but the next CDR generated contains
the ULI as U3 and so on.
generated the main ULI in CDR contains ULI as U1, but the next CDR generated contains
the ULI as U3 and so on.
5. In container the ULI is present in next container if the previous change condition is either
RAI Change, CGI-SAI Change, TAI Change, ECGI Change.
Important:
apnAmbrChange (50) -- This value is not defined in any 3GPP spec as of yet and therefore a non-
standard value is used.

The Change Time field is part of the “ChangeOfCharCondition”. element in the List of Traffic Volumes. It
provides the local time when a change condition (e.g. record closure) occurred and the container was closed.
