Hughes Software Systems Iu Interface Solution Lets OEMs Build 3G Nodes Faster

Hughes Software Systems (HSS) have launched an integrated Iu interface solution for 3G networks like SGSN (Serving GPRS Support Node), MSC (Mobile Switching Center) and RNC (Radio Network Controller).

The UMTS Iu interface enables interconnection of Radio Network Controllers (RNCs) with Core Network nodes. This distributed and highly scalable interface solution enables OEMs to build 3G nodes faster. A value added software solution- the Iu interface is available in two separate packages; Iu-Ps, and Iu-Cs, for packet switched and circuit switched domains respectively. The Iu-Cs interface interconnects between the MSC/VLR (Mobile Switching Center/ Visitor Location Register) and the RNC network nodes. The Iu-Ps interface provides interconnection between the SGSN and the RNC network nodes in UMTS/3G networks.

"This unique distributed and scalable Iu interface solution from HSS is a great value proposition for our OEM customers as it enables them to build high capacity 3G nodes faster," said Arun Kumar, President and Managing Director, Hughes Software Systems. "Innovation, research, development and domain expertise have made HSS a preferred partner of OEMs for building global communication solutions to meet the needs of the next generation networks."

The Iu is offered as an integration of standards-based RANAP (CS and PS), SCCP (Signaling Connection Control Part), implemented over either SIGTRAN (for IP network nodes) or Broadband SS7 (ATM transport). The ALCAP (AAL2 Signaling Stack) and GTP-U are also offered as optional elements. The product offering includes RANAP (Radio Access Network Application Part) encoding/decoding, UI connection management for all connection-less and connection-oriented messages, error Indication procedures, as well as complete handling of reset and reset resource elementary procedures. The solution is available on reference off-the-shelf hardware and can be further integrated on any other desired hardware.

This solution is extensible and portable, and is ideal for implementation on an embedded platform, for a variety of host-based systems ranging from high-end to low-end systems.
