This resource adaptor provides a Diameter API for JAIN SLEE applications, according to Rx interface based on Diameter protocol.
The Rx reference point is used to exchange application level session information between the Policy and Charging Rules Function (PCRF) and the Application Function (AF). This information is part of the input used by the PCRF for the Policy and Charging Control (PCC) decisions. The PCRF exchanges the PCC rules with the Policy and Charging Enforcement Function (PCEF) and QoS rules with the Bearer Binding and Event Reporting Function (BBERF).
Events represent Diameter Rx messages received by the Diameter stack. Different events types are specified for each Diameter request or answer. Events are fired either on client or server activities.
The Activities are defined by RA Type to ease use of RA. Activities represent Diameter session between two peers. SLEE applications use activities to create, send and receive messages.
