3GPP/Ro DIAMETER JAVA API

Oracle Communication and Mobility Server Developer’s Guide

The DiameterRoListener interface processes accounting messages that are received by 
the DiameterRoProviderImpl class implementing the DiameterRoProvider interface. A 
DiameterRoListener instance is registered to a provider by the following method 
DiameterRoProvider. setDiameterRoListener (). 

This interface provides four principles methods: creditControlRequestReceived(), 
creditControlAnswerReceived(), reAuthRequestReceived() and 
reAuthAnswerReceived().The first and third one must be implemented and called 
when the option AUTO_ANSWER is set to false. In this case, the server must be able 
to create an accounting answer corresponding to the received accounting request. The 
second and last methods process the received accounting answers.

The DiameterRoMessageFactory interface provides factory methods that enable an 
application to create Diameter Ro messages as defined in 3GPP: 
createCreditControlRequest(), createCreditConrolAnswer(), createReAuthRequest() 
and createReAuthAnswer(). An instance of a class implementing this interface can be 
obtained by calling the DiameterStack.getRoDiameterMessageFactory() method.

Messages created by this factory are:

■

Credit-Control-Request (CCR)

These methods create a basic CCR (with only mandatory AVPs). The first one 
creates the CCR without the Requested-Action AVP (mandatory only in event 
sessions). In the others, the method’s name specifies the Requested-Action value:
