Diameter interfaces provide connection among Diameter nodes to enable essential service provider network functions such as authentication, online and offline billing, and policy and charging.
Seamless connectivity among the many different network components in 4G LTE environments is essential to communications service providers’ (CSPs) ability to ensure service availability. It’s also essential in creating an interconnected environment that combines legacy and LTE elements. The Traffix Signaling Delivery Controller (SDC) provides support for more than 50 Diameter interfaces for rapid service enablement.
Using the SDC, CSPs can add support for new Diameter interfaces by simply uploading XML-based Diameter data dictionaries to the SDC for fast interconnection with multiple Diameter nodes.
The SDC also provides seamless and transparent support for any vendor-specific AVPs (attribute-value pairs) and can transparently handle multiple different versions of the same AVP with different encoding. If the solution needs to modify these AVPs, they can be added into the dictionary file with different names, to allow a user to access and modify these AVPs using their real names.
The SDC solution is compliant with 3GPP releases 7, 8, 9, 10, and 11. The following tables shows the complete list of interfaces the SDC supports.
