44、 the CD request was treated unsuccessful in the serving MSC. 6.4 Procedure CD_UUS_Interaction This procedure is called if the CD request was treated unsuccessful in the serving MSC due to the interaction with the UUS supplementary service. 6.5 Procedure CD_Success This procedure is called if the CD
45、request was treated successful in the serving MSC. 6.6 Procedure CD_Notify_SS_Invocation This procedure is called by the procedures CD_OR_Clear and CD_Success to send notification of the CD invocation to the gsmSCF if required. The output signal SS Invocation Notify is sent if the SS-CSI was receive
46、d in the SIFIC ack. The SS-CSI will only be included in the SIFIC ack if there is a requirement to notify the gsmSCF that CD has been invoked.
