43、o allow the SCF to influence basic call gapping procedures based in the CCF by sending information from the SCF to the SSF. The SSF relays the received information transparently to the CCF. This way, the SCF can influence the rate at which call attempts are allowed through. The operation thus influe
44、nces the filtering of calls, as opposed to service requests as is done by the Callgap operation. 4.2.1.2 Arg u ment Param eters The operation argument consists of the following parameters. These parameters are defined in clause 13. - destination Index This index is a pointer to the Destination (see
45、ITU-T Recommendation E.410 SI) to which calls are filtered. - gapIndicators The parameter contains the gapDuration and the gapInterval. - registratorIdentifier This parameter identifies the SCF and is to be used by the SSF to veriSl that the SCF is allowed to influence CCF-based call gapping procedu

SCF postcondition: 1) The SCME is
47、in the state “idle“. If the congestion level changes new “CallFIltering“ operations may be sent for active filter criteria but with a new filter interval. If the congestion situation has ended, the filtering criteria may be removed. 4.2.1.3.2 Error handling Generic error handling for the operation r
48、elated error are described in clause 13 of EN 301 93 1-2 3 and the TCAP services which are used for reporting operation errors as described in clause 10 of EN 301 93 1-1 2. 4.2.1.4 Responding entity (SSF) 4.2.1.4.1 Normal procedure SSF precondition: 1) None. SSF postcondition: 1) SSME-FSM is in the
49、state “Idle“. The SSF relays the received information transparently to the CCF-based call filtering process. In case callfiltering to the specific destinations is already active at the CCF, than the new gapIndicator parameter overwrites the existing parameter values. A manual initiated call filter will prevail over an automatic initiated call filt
