Ericsson NRG SDK for Parlay/OSA
by Edwin van Eck
Want to integrate, for example, MMS, SMS, call control, user location, or user status
with your applications? Parlay/OSA provides interfaces for these capabilities, making them
easy to use. Ericsson's NRG SDK for Parlay/OSA application development let you create
applications for Ericsson's Network Resource Gateway.
Ericsson's comprehensive Software Development Kit (SDK) for developing Parlay/OSA based
applications contains JAVA API sets, a network simulator, a graphical user interface,
example applications, and much more. The Parlay simulator – available since 2001– has
undergone major improvements and is now known as the Ericsson NRG (Network Resource
Gateway) Simulator. In addition to the simulator, the new Ericsson NRG SDK comprises a set
of tools, libraries and documentation.
No limits
OSA/Parlay opens the capabilities of the telecom network to the IT-world, creating an
enormous potential for new applications. For example, the following services can be
combined:
| User Location | It knows where the phone is. |
| User Status | It knows if the phone is on, off or busy. |
| SMS | It can now send and receive SMS messages. |
| MMS | It can now send an MMS message. |
| E-mail | It can send and receive an e-mail message. |
| WAP-push | It can now send WAP-push messages. |
| PIM Contact | It has access to the contact list of the user. |
| PIM Calendar | It also has access to the calendar of the user. |
| Call Control | It can set up phone calls to a user. |
| Multi Party call control | It can set up phone calls to many users, such
as with conferencing. |
| User Interaction | It can ask the user to type in digits on their
phone. |
| | It can also play announcements to the user. |
The new Ericsson NRG SDK for Parlay/OSA
The Parlay section of Ericsson Mobility World offers the following features:
NRG SDK with support for MMS, SMS, e-mail, WAP-push, multi-party call control,
contact list, calendar, user interaction (including announcements) user location and user
status.
Application development support for both fixed and mobile networks.
Advanced network simulation, allowing for offline development, debugging, testing
and even demonstrating your application. Note that not all Parlay APIs are included in the
simulator yet. Currently the following APIs are supported: MMS, SMS, multi-party call
control, user interaction (including announcements) and user location.
Example applications (with source code).
Demo applications (Demo Guide and source code included).
Programmers Guide for Parlay Development.
Three educational videos on Parlay Business and application development.
A complete downloadable CD (over 200 MB) covering everything needed to create your
own Parlay/OSA applications.

Additional services
In addition to its free, downloadable resources, Ericsson also offers services in
application development, training and verification of applications.
Most of the testing of your application can be done on the NRG Simulator. After simulator
testing, Ericsson can offer testing and verification services over a live test network.
Here your application is connected to an Ericsson service network via the Ericsson Network
Resource Gateway. This is connected to a wide range of enablers such as MMS-Cs, SMS-Cs,
mobile positioning centers, WAP gateways and service switching points. Ericsson also offers
software development courses, requiring basic software engineering skills and knowledge of
JAVA.
