Hughes Software Systems offers 3GPP Release 4 Application
Solutions for IP based Wireless Networks
Announces Development of 3GPP Release 5 Compliant Stacks
January 27 2003, New Delhi, India
Hughes Software Systems, world leaders and specialists in
convergent network software, added to its growing list international
standards based protocol stacks by introducing Release 4 compliant
versions of its MAP (Mobility Application Part), CAP (CAMEL
Application Part) and RANAP (Radio Access Network Application
Part) stacks. These stacks enable equipment vendors, test
and measurement tool vendors, and application developers to
develop solutions for RNC (Radio Network Controller), SGSN
(Serving GPRS Support Node), MSC (Mobile Switching Center),
HLR (Home Location Register), and Application servers. A unique
differentiation is the integrated support of these stacks
over SS7 as well as SIGTRAN, providing truly converged solutions
that can run over ATM, T1/E1 or IP.
Along with these releases, HSS has also taken the lead in
the Protocol stacks adherence to standards by defining its
product roadmaps for Release 5 compliance in the near future.
As a result, HSS customers can be sure that HSS offerings
will remain compliant to the evolving standards, effectively
eliminating the risk of end equipment obsolescence.
3GPP Release 4 are specifications by the 3G Partnership Project,
the standard making body for third generation mobile telephony,
for all GPRS/UMTS network elements. The main purpose of 3GPP
R4 is to introduce separation of connection, its control and
services for the Circuit Switched Core Network to make it
freely scalable. It also aims to route a part of voice calls
over IP, thus facilitating the transition to all IP networks.
In addition, it introduces several new service concepts to
enhance the user experience. Complying with Release 4 will
be essential for operators as they move to an all IP network
to cut costs, optimize their networks and offer new services
to their customers.
Beyond Release 4, 3GPP Release 5 aims to route the entire
data and voice traffic over IP rather than over a host of
transport protocols as in current wireless networks. An all
IP wireless network can seamlessly connect to Internet and
other IP based networks. This will make it extremely cost-effective
and convenient for wireless networks to carry data and voice,
and to interoperate with each other.
HSS has integrated its MAP & CAP stacks with its SS7/SIGTRAN
offering to provide a complete "black box" solution
to application developers, enabling them to connect their
mobility/billing/service applications to the 3G network. The
RANAP stack has been integrated with the SS7/Sigtran to form
the IuCS and IuPS Interfaces, which connect RNC to SGSN and
MSC. These integrated offerings dramatically reduce the cost,
time to market, and development risks of companies developing
related solutions.
All HSS stacks are designed with operating system and platform
independence as a design goal, thereby enabling customers
to migrate to newer platforms in keeping with the needs of
the market and profit margin requirements, as well as presenting
the much needed option to its customers to choose their own
hardware and Operating system for new product designs.
Glossary of Terms used:
MAP:
The totality of a mobile application system (sometimes also
called a wireless application) is often referred to as a Mobile
Application Platform, and consists of two or more Mobile Application
Parts (MAP). It enables signaling between different network
entities. Some MAPs have specific data definition, transaction
definition, overall output and input definition, and processing
rules. The MAP stack is built on top of the Transaction Capabilities
Application Part (TCAP) layer, which is the top most layer
of the Signaling System Number 7 (SS7) stack.
CAP: CAP is an important component of mobility networks
used to implement CAMEL (Customized Applications for Mobile
Network Enhanced Logic). CAMEL is an extension of Intelligent
Network (IN) concept in GSM. However, an important difference
between the two is that CAMEL can provide mechanisms to support
services consistently independently of the serving network,
thus enabling the user to experience uniform services even
when she is outside the home network. Just like MAP, the CAP
stack is built on top of the Transaction Capabilities Application
Part (TCAP) layer.
RANAP:
The Radio Access Network Application Part manages the communication
between the 3G Radio Network Controller, the 3G Serving GPRS
Support Node and the 3G Mobile Switching Center.
SS7:
Signaling System Number 7 (SS7) is the international digital
signaling standard based on Common Channel Signaling (CCS)
between Central Office switches worldwide.
Signaling System No. 7 (SS7) is a global standard for telecommunications
defined by the International Telecommunication Union (ITU)
Telecommunication Standardization Sector (ITU-T). The standard
defines the procedures and protocol by which network elements
in the public switched telephone network (PSTN) exchange information
over a digital signaling network to effect wireless (cellular)
and wireline call setup, routing and control. It is an industry
proven protocol stack for building telecom equipment, network
components as well as SS7 based applications.
The SS7
network and protocol are used for:
- basic call setup, management, and tear down
- wireless services such as personal communications services
(PCS), wireless roaming, and mobile subscriber authentication
- enhanced call features such as call forwarding, calling
party name/number display, and three-way calling
- efficient and secure worldwide telecommunications
SIGTRAN:
SIGTRAN was developed by the IETF working group SIGTRAN and
defines the control protocol between the Signaling Gateway,
Media Gateway Controllers and IP based Signaling Points. The
Sigtran protocol consists of a modular, extensible structure
with a common reliable transport protocol used for all signaling
transport. The protocol transports message based signaling
protocols messages, usually SS7, transparently over IP networks.
