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.
