MBMSUmtsIRISequence ::= SEQUENCE OF MBMSUmtsIRIContent

— Aggregation of MBMSUmtsIRIContent is an optional feature.

— It may be applied in cases when at a given point in time

— several IRI records are available for delivery to the same LEA destination.

— As a general rule, records created at any event shall be sent

— immediately and not withheld in the DF or MF in order to

— apply aggragation.

— When aggregation is not to be applied,

— MBMSUmtsIRIContent needs to be chosen.

off-online-action (3),

— in case of MBMS, this indicates a subscription management event has occurred as the

— result of an MBMS operator customer services function or other subscription updates

— not initiated by the MBMS UE.
