is global. Network coverage is important.
GSM and ANSI-41 (TDMA, CDMA, and AMPS) wireless networks are
incompatible.
If you are an ANSI-41 carrier,
you want to offer service coverage to your subscribers while roaming into GSM
areas.
Synacom Technology's RoamFree®
Gateway 200 provides you with the solution for this problem.The RoamFree®
Gateway 200 eliminates the problems presented by incompatible network standards
by providing seamless interoperability between ANSI-41 and GSM networks. Wireless
carriers now have a cost-effective method to expand coverage to regions that were
formerly off limits. With the RoamFree® Gateway
200, carriers can offer the following features:
Registration
Call delivery
Call forwarding
Multiparty calling
Call waiting
Call barring
Short Message Services (Mobile Origination & Mobile Termination)
Synacom's RoamFree® Gateway
200 solution provides more than just interworking between
ANSI-41 and GSM; it also provides fraud containment while
roaming. The RoamFree®
Gateway has incorporated a GSM Authentication Center application
within the RoamFree® Gateway
200 product.
| | | The
RoamFree® Gateway
200 interworking solution | | |
Synacom's RoamFree® Gateway 200 interworking
solution implements protocol conversion, database mapping and transaction management
for all of the functions supported between the networks as a single, separate
network element as shown in the following figure. It provides an IWF solution
that requires no changes to existing ANSI-41 or GSM networks and can reside external
or internal to either of the networks.
The RoamFree® Gateway appears
as the home location register (HLR) to the GSM network serving
the roaming subscriber, and as the serving visitor location
register (VLR) to the subscriber's home ANSI-41 network.
RoamFree Gateway Features
Total compatibility between ANSI-41 and GSM is not generally
feasible. Many ANSI-41 features are simply not offered in GSM
(and vice versa). However, with the RoamFree®
Gateway 200, a large number of services are available when an
ANSI-41 subscriber roams into a GSM market. Contact Synacom
Technology for a complete list of features and functions.
Authentication Features
The RoamFree® Gateway 200
consolidates the standard GSM authentication application onto the RoamFree®
Gateway Platform. The RoamFree® Gateway Authentication
Center (AuC) function is invoked by the RoamFree®
Gateway HLR functions when the serving VLR requests authentication of the subscriber.
The AuC adheres to the GSM authentication standard. Its capabilities include triplet
generation (RAND, SRES, and Kc) and use of the A3/A8 algorithms.
RoamFree Management Application
The RoamFree Gateway's user-friendly administration application
provides intuitive methods to provision subscribers and monitor
alarms and system performance.
RoamFree Gateway hardware
The RoamFree Gateway system uses the Compaq AlphaServer product
family as its hardware computing platform. The AlphaServer products
used in the RoamFree Gateway system are scaleable, dependable,
open systems that deliver high performance at an affordable
price. Powerful symmetric multiprocessing (SMP) servers, the
AlphaServer systems provide for growth and configuration flexibility.

TruCluster Production Server software |
| |
The RoamFree Gateway employs
a Compaq TruCluster Production Server system to field
a high-availability, high-performance telephony system.
The TruCluster Production Server integrates AlphaServer
platform, an integrated disk subsystem, and the Memory
Channel interconnect. This cluster system, with the addition
of the Oracle Parallel Server, provides RoamFree with
an extremely high-performance database delivery engine.

|
Oracle database management system |
| |
The RoamFree Gateway uses the Oracle database
management system as its database server.
|
|
|
Fault management |
| |
The RoamFree® Gateway automatically
monitors hardware and software to detect and correct subsystem
failures. It accomplishes this task using proprietary
software with inputs from DECevent. |
