The Aricent IMS client is a software framework for developing new IMS-based client applications. The following figure briefly illustrates the architecture of the framework.

IMS Client Framework Overview

In effect, it is a platform that provides the complete set of functionalities: signaling, media access, and device management, that are required to develop IMS client applications residing on the handset.

• IMS Signaling: Provides the signaling protocol and session control to setup up application level sessions with the IMS core network. It handles the complexity of IMS registration, authentication, QoS, session control and non-session control elements, such as MESSAGE and PRESENCE.
• Media Access: Provides protocol and functionality for high-quality, real-time transfer of audio and video. It supports RTP and RTCP, provides audio/video codecs, echo cancellation, and other sophisticated media functions.
• Device Management: Provides protocols and functionality for configuration and provisioning of the IMS client using protocols, such as the XML Configuration Access Protocol (XCAP)
  

Key Features

1. Horizontal services architecture
2. Extensive set of high level API
3. Platform independent
4. Pre-integrated with Media codecs (Optional)
5. Modular and extensible with Low footprint
   

Value Addition

The Framework provides the following value:

1. The horizontal layered architecture supports multiple applications on top. It thus reduces memory footprint and offers a common look and feel across applications.
2. By hiding the complexity of the IMS and SIP signaling through its high level APIs, it allows application developers to focus their energies on creating innovative triple play applications with new features and new utilities.
3. Because of its modular and reusable architecture, with the basic IMS constructs being offered as building blocks that provide for easy mixing and matching; fine tuning, modifying, or adding features to applications becomes possible with minimal effort, reducing time-to-market.
4. The interoperability with core infrastructure elements built into the product ensures that applications developed using our product are ready-to-deploy.
5. Platform independence of the framework implies that the same application can be deployed across handsets and operating systems, further reducing deployment costs.

Platforms Supported

1. WinCE
2. Windows XP
3. Embedded Linux
4. Symbian
5. Brew
6. Proprietary embedded operating systems

Platform Integration and Application Development

Apart from the above operating systems, Aricent also offers its expertise for targeted application development as well for their integration with proprietary operating systems.

Aricent also offers the following innovative applications leveraging the IMS client framework that would augment any service provider's portfolio significantly.

• The Visitor Management System: Is an application targeted at the enterprise/home sector that allows users in the corporate/home environment, irrespective of their location, stay in touch with visitors
• PTT Alerts: Is an application built on the PTT architecture that allows a central user alert a distributed subscriber base using text, audio, or video, in real-time or at pre-set intervals.
• The Gaming Application: Is an application that allows multiple players enjoy a game of chance again over a PTT Client server arrangement.
• Softphone: An application that allows voice to be transmitted as data over a packet based network.
