Wireless-signaling solutions provider IntelliNet Technologies has extended its Diameter Routing Agent (DRA) with the addition of the Diameter Edge Agent (DEA), Subscriber Location Function (SLF) and Interworking Function (IWF) as defined by the 3GPP, IETF and GSMA standards bodies. The product suite is known as the Diameter Routing Engine.
Most wireless networks are converging on the LTE standard, while unprecedented data growth is causing an explosion in signaling traffic. This has given rise to a new class of product referred to as a Diameter Signaling Controller (DSC) that addresses the growth and expected congestion in signaling traffic by efficiently routing signaling information. IntelliNet says its Diameter Routing Engine provides load balancing, roaming and interworking with legacy networks. It can be configured to the operator’s exact requirements.
“IntelliNet recently sold off its data offload business including its Wi-Fi Offload Gateway and Femtocell Gateway," said Anjan Ghosal, IntelliNet’s president and CEO. “We have refocused the company in the Diameter signaling area that has become very important to LTE network operators."
There are many network elements that need to interconnect using Diameter in Evolved Packet Core (EPC) and IP Multimedia Subsystem (IMS) networks as well as interconnection to legacy networks. If there are multiple instances of the Diameter clients and servers then this results in a mesh of connections that are difficult to scale and manage. The DSC is deployed at the network core in a configuration that routes the signals through a hub rather than a mesh network.
IntelliNet plans to show off the routing engine at Mobile World Congress in Barcelona this month.
