The HLR determines that the dialed digits include a Cancel Call Waiting (CCW)request and that the MS is authorized for this service and sends a featreq to the

27、Serving MSC. The featreq includes call routing information in the TerminationListparameter (e.g. based on the Termination Address extracted from the dialed digits).

A call involving the served MS is in progress.b. A call origination and the dialed MS address

39、digits (i.e., directory number) are receivedby the Originating MSC.c. The Originating MSC sends a LOCREQ to the HLR associated with the MS; thisassociation is made through the dialed MS address digits (which may not be the MIN).d. If the dialed MS address digits are assigned to a legitimate subscrib

40、er, the HLR sendsa ROUTREQ to the VLR where the MS is registered.e. The VLR then forwards the ROUTREQ to the current Serving MSC.f. In reaction to the ROUTREQ, the Serving MSC checks its internal data structures anddetermines that the MS is busy in another call but has CW active (due to MSs profileo

41、r indicated by the OTFI). Therefore, the Serving MSC allocates a TLDN (TemporaryLocal Directory Number) and returns this information to the VLR in the routreq.g.
