The document lists operations for INAP and CAP signaling protocols. It describes over 30 operations, including their direction (SCF to/from SSF, SRF) and basic purpose (e.g. request call event reports, play announcements, apply charging). The operations allow the SCF to control call processing, collect information from users, and monitor events reported from SSFs and SRFs.

1. Summary of INAP and CAP Operations
Operation CS1+ CS1 CAP V1 CAP V2 Direction Description
ActivateServiceFiltering Y Y SCF --> SSF
When receiving this operation, the
SSF handles calls to destinations in
a specified manner without request
for instructions to the SCF. In the
case of service filtering, the SSF
executes a specific filtering
algorithm.
ActivityTest Y Y Y Y
SCF --> SSF
SCF --> SRF
This operation is used to check the
continued existence of a relationship
between the SCF and the SSFp g
ApplyCharging Y Y Y SCF --> SSF
from the SCF with the SSF Charging
mechanisms. The
'ApplyChargingReport' operation
provides the feedback from the SSF
ApplyChargingReport Y Y Y SCF <-- SSF
This operation is used by the SSF to
report charging related information to
the SCF as requested by the SCF
using the ApplyCharging operation
AssistRequestInstructions Y Y Y
SCF <-- SSF
SCF <-- SRF
This operation is sent to the SCF by
an SSF/SRF, which is acting as the
assisting SSF in an assist or hand-
off procedure, or by an stand alone
SRF(IP).
CallGap Y Y SCF --> SSF
This operation is used to request the
SSF to reduce the rate at which
specific service requests are sent to
the SCF
CallInformationReport Y Y Y SCF <-- SSF
This operation is used to send
specific callinformation as requested
by the SCF in a previous
'CallInformationRequest' operation
CallInformationRequest Y Y Y SCF --> SSF
This operation is used to request the
SSF to record specific information
about a call and report it to the SCF
using the 'CallInformationReport'
CallLimit Y SCF --> SSF
This operation activates a window
mechanism in the SSF which
provides a dynamic call flow
regulation to prohibit an
Cancel Y Y Y SCF --> SSF
The SCF uses this operation to
request the SRF to cancel a
correlated previous
'PlayAnnouncement' or a
'PromptAndCollectUserInformation'
operation. The Cancel operation can
also be used to cancel all
outstanding requests (EDP's and
Reports).
CollectInformation Y Y SCF --> SSF
This operation is used to request the
SSF to perform the basic originating
call processing actions which will
collect destination information from a
calling party.
Connect Y Y Y Y SCF --> SSF
This operation is used to request the
SSF to perform the call processing
actions to route a call to a specific
ConnectToResource Y Y Y SCF --> SSF
This operation is used to connect a
specialized resource.
Continue Y Y Y Y SCF --> SSF
This operation is used to request the
SSF to proceed with call processing
at the DP at which it previously
suspended call processing to await
SCF instructions.
DialogueUserInformation Y SCF <--> SSF
This operation is sent at the
beginning of a dialogue and requests
the connection of test equipment for
the duration of the dialogue.
DisconnectForwardConnection Y Y Y SCF --> SSF
To clear a connection to a SRF. It is
used to explicitly disconnect a
connection to a resource (SRF)
established previously with an
'ConnectToResource' operation.
EstablishTemporaryConnection Y Y Y SCF --> SSF
This operation is used to create a
connection between an initiating
SSF and an assisting SSF as part of
a service assist procedure.

2. Summary of INAP and CAP Operations
the to
Operation CS1+ CS1 CAP V1 CAP V2 Direction Description
EventNotificationCharging Y Y SCF <-- SSF
This operation is used to report to
the SCF the occurrance of a specific
charging event type as requested by
the SCF using the
'RequestNotificationChargingEvent'
operation.
EventReportBCSM Y Y Y Y SCF <-- SSF
This operation is used to notify the
SCF of a call related event
previously requested by the SCF in a
'RequestReportBCSMEvent'
operation.
FurnishChargingInformation Y Y Y SCF --> SSF
This operation is used to request the
SSF to include some information in a
call record.The registered call record
is intended for off-line charging of the
call.
HandOver Y SCF --> SSF
This operation is sent by the SCF in
order to pass the control relationship
to another SCF.
HoldCallPartyConnection Y SCF --> SSF
The HoldCallPartyConnection
operation is used to place a
particular call party on hold.
InitialDP Y Y Y Y SCF <-- SSF
This operation is sent by the SSF
after the detection of a Trigger
Detection Point, to request the SCF
for instructions to complete the call.
This operation is sent by SCF
InitiateCallAttempt Y Y SCF --> SSF
request the SSF to setup a call to
one call party using the address
information provided by the SCF.
PlayAnnouncement Y Y Y SCF --> SRF
This operation is used for inband
interaction with an analogue user or
for interaction with an ISDN user.
PromptAndCollectUserInformation Y Y Y SCF --> SRF
This operation is used to interact
with a call party in order to collect
information.
Reconnect Y SCF --> SSF
This operation is used to request the
SSF to retrieve a particular call party
connection from hold. It is the
inverse of the
HoldCallPartyConnection operation.
ReleaseCall Y Y Y Y SCF --> SSF
This operation is used by the SCF to
tear down an existing call at any
phase of the call.
ReleaseCallPartyConnection Y SCF --> SSF
This operation is used by the SCF to
order a forced release of a specific
call party at any phase of the call.
RequestNotificationChargingEvent Y Y SCF --> SSF
This operation is used to instruct the
SSF how to manage the charging
events which are received from other
Function Entities, not under the
control of the SCP.
RequestReportBCSMEvent Y Y Y Y SCF --> SSF
This operation is used to request the
SSF to monitor for call related
events (ISUP events such as busy or
no answer), and send a report back
to the SCF when the event is
detected.
answer), and send a report back to
the SCF when the event is detected.
ResetTimer Y Y Y SCF --> SSF
This operation is used by the SCF to
refresh the Tssf application timer, in
order to avoid a Tssf time-out at the
SSF.
Retrieve Y SCF --> SDF
This operation is used to retrieve
information held in a database.
SendChargingInformation Y Y Y SCF --> SSF
This operation is used to instruct the
SSF on the charging information to
be sent by the SSF.
ServiceFilteringResponse Y Y SCF <-- SSF
This operation is used to report the
values of counters specified in the
previous sent
'ActivateServiceFiltering' operation to
the SCF.

SignallingInformation Y SCF --> SSF
This operation is used to provide
control information in order to
influence or overwrite signalling
information conveyed in the network.
SpecializedResourceReport Y Y Y SCF <-- SRF
This operation is used as the
response to a 'PlayAnnouncement'
or
'PromptAndCollectUserInformation'
operation when the announcement
started/completed indication is set.
Update Y SCF --> SDF
This operation is used to write data
into a database function.
