Describes incoming events to the calling application. It contains an event type and a service provider ID that are common to all received events and an event-specific section:
typedef struct Tcap_Recv_Info
{
U8 eventType; /* Event type... */
U8 spare; /* spare for alignment */
S16 suId; /* TCAP SAP ID event belongs to */
union /* event-specific info */
{
TcapCoordEvent coord; /* coord indication/confirm */
TcapPCStateEvent pcstate; /* SP state change */
TcapSsnStateEvent ssnstate; /* subsystem state change */
TcapNotifEvent notif; /* undeliverable msg notify */
TcapStatusEvent status; /* TCAP error indication */
TcapTransEvent; data; /* transaction data */
} event;
} TcapRecvInfo;
The TcapRecvInfo structure contains the following fields:
|
Field |
Description |
|
eventType |
Identifies the event received, and determines which event-specific union member is used. 0xB1 = TCAP_EVENT_DAT_IND Transaction data indicator 0xB2 = TCAP_EVENT_STA_IND Status (error) indicator 0xB3 = TCAP_EVENT_COORD_IND Coordinated state change indication 0xB4 = TCAP_EVENT_COORD_CFM Coordinated state change confirmation 0xB5 = TCAP_EVENT_SSN_STATE Subsystem state change 0xB6 = TCAP_EVENT_PC_STATE SP state change 0xBF = TCAP_EVENT_NOT_IND Notice indication (SCCP undeliverable message return) |
|
suID |
Identifies the TCAP SAP to which the incoming message belongs. This is useful to applications that bind to more than one TCAP SAP, such as ones that implement multiple subsystems in a single application. |
