Introduction

The purpose of this document is to describe the XML based protocol used to implement communication between the YATE Diameter implementation and the Diameter application servers for mobile services so that exchange of Diameter information between YATE and application servers can be done over TCP connections.

Diameter is an authentication, authorization, and accounting protocol for computer networks. In LTE, several Diameter applications are defined and used. The primary aim is to allow applications servers to handle and send Diameter commands regarding the S6a interface (MME - HSS interface).

The aim of the protocol is to map Diameter commands from the interface and any other relevant information needed for the transport of the command to XML messages as transparently as possible.
