A call origination with a dialed MS address digits (i.e., directory number) is receivedby the Originati
26、ng MSC. Also included in the call origination is calling numberidentification (CNI) information, which may include: one or two calling partynumbers, a calling party subaddress, a redirecting number, and a redirectingsubaddress.b. The Originating MSC sends a LOCREQ to the MSs HLR, including parameter
27、s basedon the CNI information received in Step a.c. The HLR constructs a ROUTREQ, including parameters based on the CNI informationreceived in Step b, and sends it to the VLR where the MS is registered.d. The VLR forwards the ROUTREQ to the current Serving MSC. Parameters are as inStep c.e. In react
28、ion to the ROUTREQ, the Serving MSC checks its internal data structures anddetermines that the MS is currently idle. Therefore the Serving MSC allocates a TLDNand returns this information to the VLR in the routreq. The Serving MSC stores thereceived CNI information.f. The VLR sends the routreq to th
29、e HLR.g. When the routreq is received by the HLR, it returns a locreq to the OriginatingMSC. The locreq includes routing information in the form of the TerminationListparameter, along with an indication of the reason for extending the incoming call (i.e.,for CD) in the DMH_RedirectionIndicator param
