HP OpenCall Universal Signaling Platform Diameter is an implementation of the IETF specification RFC 3588: Diameter Base Protocol, which defines a network protocol for Authentication, Authorization and Accounting (AAA), and of higher level AAA applications defined by the 3GPP consortium. The product provides both C++ and Java programming interfaces. The Base Protocol implementation is designed to be easily extensible to any Diameter application.

Architecture Overview |
|
|
|
|
The OpenCall Diameter Base Protocol library contains the implementation of RFC 3588, and is available as a C++ shared library. It defines an application registration mechanism used by the 3GPP APIs, as well as the Java programming interfaces to provide additional services.
On its lower side, OpenCall Diameter also defines a C++ API to interact with transport modules. A socket-based implementation is provided. The OpenCall Diameter Base Protocol library exports APIs to support all configuration needs, including realm based routing table configuration, generic tracing and logging callbacks, external memory manager support, and dynamic protocol dictionary extensibility. The product may be managed via SNMP or Java MBeans.

OpenCall Diameter C++ APIs |
|
|
|
|
The Base Protocol library acts as an event-driven protocol engine. Events are delivered between the Diameter Base Protocol library and other components (transport, user application) via C++ method invocations. By extending the classes defined by OpenCall Diameter, the programmer can adapt the product to suit specific needs.
Supported C++ APIs are:- Diameter Base Protocol ( RFC3588 )
- CCA ( RFC4006 )
- 3GPP Sh ( TS 29.328, TS 29.329 )
- 3GPP Ro and Rf ( TS 32.299, TS 32.240 )
- 3GPP Cx and Dx ( TS 29.228, TS 29.229 )

OpenCall Diameter Java APIs |
|
|
|
|
The HP OpenCall Universal Signaling Platform Diameter Java API was designed for easy integration with JAIN-compliant protocol APIs, typically with SIP in an IMS environment. It offers the same possibilities as its C++ counterpart.
Supported Java APIs are:- Diameter Base Protocol (RFC3588)
- CCA ( RFC4006 )
- 3GPP Sh ( TS 29.328, TS 29.329 )
- 3GPP Ro and Rf ( TS 32.299, TS 32.240 )
- 3GPP Cx and Dx ( TS 29.228, TS 29.229 )
