The Standalone Service Creation Environment (SCE) product
from HSS is being used by OEM customers to create next generation
enhanced applications, services as well as call related features.
These OEM customers chose to use the adaptable SCE programming
environment from HSS instead of using conventional methods
on account of the value this product delivers to them in terms
of their ability to deliver enhanced applications to their
service operator customers quicker than their competitors
and that too at reduced costs.

Softswitch platform for Class 5
features |
The HSS SCE is a standalone product, which meets the requirements
for end-to-end service creation and integration for both proprietary
as well as standards based core networks and application platforms.
SCE delivers true customer value on a sustained basis by enabling
rapid development and maintenance of revenue generating services
at reduced costs, faster time to market for new applications
and quick turnaround for customer specific application customization
needs.
The HSS Service Creation Environment entails absolute savings
in developmental efforts, maintenance and customization efforts
as well as soft savings which are guided by the opportunity
cost. The benefit of the Service Creation Environment increases
with the increase in the number of features / applications.
Using the HSS SCE, the absolute savings in development effort
is over 50% while the maintenance and customization effort
comes down by over 50%.
The HSS Service Creation Environment also reduces the opportunity
value for time-to-market, with elapsed time savings of over
50% and improves the turn-around for customer specific needs
The HSS SCE can be adapted to create any application for
standardized interfaces and it is not tied up to any specific
underlying platform or technology. The fully functional out
of the box software solution after adaptation supports user
defined dynamic plug and play of new components (third party
application development support).
The SCE generated applications and services are currently
running on OEM platforms and the following section provide
details on SCE usage by some of our OEM customers for a service
platform as well as a Softswitch Platform.
SCE generated services for Enhanced Call Server (ECS) platform
in IP domain
The Enhanced Call Server (ECS) is a hardware and software platform
for creation, development, distribution, management and execution
of services. The Enhanced Call server (ECS) is an "Adjunct
System" to a PSTN switch for either IN (Service Node/SCP/SRF)
type of services or for protocol inter-working type of services.
It can also act as an independent network element type of device
for the Media Gateway Controller or Gatekeeper functionality.
The figure above
shows ECS deployment in a Network: and logical placement of
SCE for generating applications.
In this configuration the ECS Server acts as a Service Deployment
Platform. The Server provides a Service Creation, Deployment,
Service Control and Service Resources functionality using
the SCE and SMS software solutions. It interacts with the
PSTN switch using the INAP/ISUP and with PINT server using
SIP Protocol. It also interacts with the SMS using a TCP/IP
connection.
Service Creation Environment (SCE) and Service Management
System (SMS) are independently hosted applications (they run
on a platform other than ECS) which are part of the ECS solution.
The SCE is a Java based system which helps in creation of
services whereas SMS is a Sun Solaris based application which
helps in building, deployment, start, stop and monitoring
of services. The SCE is used to create services which are
then deployed on the Server.
The services developed using SCE are IN based services such
as calling card, toll free, call screening, call forwarding
and distribution, SIP/ PINT based services like Click to dial,
click to fax and others.
Softswitch Platform for CLASS 5 Features
Development of CLASS 5 features for the softswitch using HSS
SCE. Here, CS1/CS2 ETSI/ITU-T/AIN 0.2 based SIBs are used
for the development of services using INAP Adapter and the
interface Service framework/MGC.
The Softswitch provides service framework and call control
functionality, which will be in turn called by INAP Adapter
and vice-versa. The figure above
shows the Softswitch platform for Class 5 features.
The sample list of services created using SCE are calling
name delivery, N11, Call ID blocking, 3-way calling, call
waiting, call forwarding etc.
