Popis: The Diameter protocol was initially developed by the Internet Engineering Task Force (IETF) as an Authentication, Authorization, and Accounting (AAA) framework intended for applications such as remote network access and IP mobility. Diameter was further embraced by the Third Generation Partnership Project (3GPP) as the key protocol for AAA and mobility management in 3G networks. The paper discusses the use of Diameter in the scope of the IP Multimedia Subsystem (IMS) as specified by 3GPP, with special emphasis on its use on the Cx interface between the Call Session Control Function (CSCF) and the Home Subscriber Server (HSS). The goal of this work was to implement basic Diameter functionality corresponding to the Cx interface. The paper compares a number of open source implementations of the Diameter Base Protocol, and provides the rationale for choosing the Open Diameter solution for implementation purposes. Experiences regarding installation, configuration and implementation of basic authorization functionality using Open Diameter are discussed. The resulting implementation is verified in a laboratory testbed.
