Description

SKIM_Api::Initialize()

Initializes a SKIM API object. This method also initializes SKTAL and registers a TCAP SSN with the CSP.

SKIM_Api::Terminate()

Terminates the SKIM API object and performs cleanup functions. This method terminates SKTAL and deregisters a TCAP SSN with the CSP. All pending dialogs associated with SKIM_Api object are cleared by sending a pre-arranged end message to the CSP.

SKIM_Api::Send

Sends TCAP transaction message along with a list of operations. A given transaction message can contain zero or more operations (TCAP Components).

SKIM_Api::SSNInService

Sends N-State request to bring the local subsystem network (SSN) in service.

SKIM_Api::SSNOutOfService

Sends N-State request to take the local SSN out of service.

SKIM_Api::SendReject

Allows the user to send TCAP Reject message for a given invoke ID and call reference ID. This method also terminates the transaction by sending TCAP End.

SKIM_Api::CancelOperation

Allows the user to cancel a previously invoked operation for a given call reference ID and invoke ID.

SKIM_Api::SendPreArrangedEnd

Sends a pre-arranged end message for a given call reference ID.

SKIM_Api::SetTransHandler

Sets a transaction handler for a given call reference ID.

SKIM_Api::ClearTransHandler

Clears a transaction handler for a given call reference ID.

SKIM_Api::EnableTracing

Enables SKIM library tracing for a given trace type.

SKIM_Api::DisableTracing

Disables SKIM library tracing for a given trace type.

Name

Despcription

sktal_initializeTCAP

A one-time call for global initialization of the TCAP Abstraction layer.

sktal_terminateTCAP

A one-time call for global termination of the TCAP Abstraction layer.

sktal_registerTCAPSSNHandler

Registers the application with a given node/stack/subsystem. A generic handler will be added to the handler stack that will filter messages for the given subsystem. When a new TCAP transaction is seen, or when sk_TCAP_AllocateDialogueID is called, the NewDialogueHandler function argument will be invoked. This function is expected to register a per dialogue handler (via sktal_setTCAPSSNHandler) for the new dialogue. All incoming messages within that dialogue sequence will be passed to that handler.

sktal_unregisterTCAPSSNHandler

Removes (and terminates) the subsystem identified during registration. All ongoing transactions are terminated and the subsystem is marked out-of-service.

sktal_allocateTCAPDialogID

Allocates the TCAP dialogue ID.

sktal_setTCAPDialogHandler

Specifies a function to be invoked for incoming messages within a given transaction (identified by the Dialogue ID). The incoming event and the Dialogue ID invoke the handler; the handler should examine the event and invoke either sktal_recvTCAPDialogue or sktal_recvTCAPComponent.

sktal_clearTCAPDialogHandler

The user removes the transaction handler once the transaction has been completed (by receiving) TC-U-ABORT, TC-P-ABORT, TC-END, or TC-UNI, or sending TC-U-ABORT, TC-END, or TC-UNI). It is imperative to not take this step until the last message has been sent.

sktal_sendTCAPDialog

Sends a TCAP dialogue message.

sktal_recvTCAPDialog

Receives a TCAP dialogue info from a SKTAL_EVENT.

sktal_sendTCAPComponent

Sends a TCAP component message.

sktal_recv_TCAPComponent

Receives TCAP component information from a SKTAL_EVENT.
