SUPERVISION_TIMER_DURATION

INTERIM_INTERVAL

REALTIME_REQUIRED

The default value of the INTERIM_INTERVAL and REALTIME_REQUIRED options 
can be overwritten dynamically by the application for a specific session by using the 
setSessionParameter() method.

As presented in the [RFC 3588], different types of accounting records are sent 
depending on the actual type of accounted service. 

If the accounted service is a one-time event, meaning that the start and stop of the 
event are simultaneous, then the Accounting-Record-Type AVP must be set to the 
value EVENT_RECORD.

If the accounted service is of a measurable length, then the AVP must use the values 
START_RECORD, STOP_RECORD, and possibly, INTERIM_RECORD.

Here are the two different messages flows which can be handled by the Rf Diameter 
application.

One-time event accounting service:

■

Client > ACR (EVENT_RECORD) > Server

■

Client < ACA (EVENT_RECORD) < Server

Measurable length duration accounting service:

■

Client > ACR (START_RECORD) > Server

■

Client < ACA (START_RECORD) < Server

■

Client > ACR (INTERIM_RECORD) > Server

■

Client < ACA (INTERIM_RECORD) < Server

■

Client > ACR (INTERIM_RECORD) > Server

■

Client < ACA (INTERIM_RECORD) < Server

■

Client > ACR (STOP_RECORD) > Server

■

Client < ACA (STOP_RECORD) < Server

ACR(EVENT_RECORD) stands for Accounting-Request message with 
Accounting-Record-Type AVP set to EVENT_RECORD and request flag set to true.

ACA(EVENT_RECORD) stands for Accounting-Answer message with 
Accounting-Record-Type AVP set to EVENT_RECORD and request flag set to false.

Below are the different types of FSM which can be implemented in Rf application.

This FSM responds to the [RFC 3588] requirements which define the 

client side state machine. 

A session instantiated by an application implementing this FSM expects to receive an 
accounting request message including an Accounting-Record-Type AVP value set to 
EVENT_RECORD or START_RECORD as first received message. 

Once an accounting request message with the Accounting-Record-Type AVP value set 
to START_RECORD is received, the FSM expects to receive other(s) accounting 
request message(s) with the Accounting-Record-Type AVP value set to INTERIM_
