hi3CSDomainId [0] OBJECT IDENTIFIER OPTIONAL, — 3GPP HI3 CS Domain.

— When FTP is used this parametr shall be sent to LEMF.

— versions 2-7 were omitted to align with UmtsHI2Operations.

version8(8)

} OPTIONAL,

— Optional parameter "version" (tag 23) became redundant starting from

— 33.108v6.8.0, where the object identifier "hi3CSDomainId" was introduced into

— "UMTS-Content-Report". In order to keep backward compatibility, even when the

— version of the "hi3CSDomainId" parameter will be incremented it is recommended to

— always send to LEMF the same: enumeration value "lastVersion(8)".

lawfulInterceptionIdentifier [6] LawfulInterceptionIdentifier OPTIONAL,

communicationIdentifier [1] CommunicationIdentifier,

— Used to uniquely identify an intercepted call: the same as used for the relevant IRI.

— Called "callIdentifier" in edition 1 ES 201 671.

content [4] Supplementary-Services OPTIONAL,

— UUI are encoded in the format defined for the User-to-user information parameter

— of the ISUP protocol (see EN 300 356 [30]). Only one UUI parameter is sent per message.
