The IE RRC-TransactionIdentifier is used, together with the message type, for the identification of an RRC procedure (transaction).

RRC-TransactionIdentifier ::= INTEGER (0..3)

UE shall set the rrc-TransactionIdentifier in the response message, if included, to the same value as included in the message received from E-UTRAN that triggered the response message

source: RRC spec 36.331 (section 6.3.6)

Usually, I always saw when UE sends "S-TMSI" in RRC connection Request message then it definitely sends "Registered MME Information " in RRC Connection Setup Complete message.
