IMS

The wireless telecommunications industry is evolving from wireless voice to converged wireless voice, video and data over next-generation networks.
IMS is now best viewed as an IP Multimedia System that will provide a unified architecture, end-user devices with IP multimedia capabilities, and the systems integration necessary to provide any IP multimedia services for and between any set of wireline and wireless end-users.
Cellular operators continued to steadily roll out new 3G systems in 2005, though the rate of new deployments has slowed. For the most part, carriers will take a breather over these next few years and refine the networks they already have, while developing new features to make use of those networks. The worldwide 3G subscriber base will grow from 29.1 million in 2004 to 540 million in 2010 (In-stat research).
The IMS was designed for mobile networks but is being leveraged for fixed networks as well, because IMS offers common platforms for subscriber profiles, authentication, and billing, as well as IP session routing.

teleSys MACH7 development platforms create a blueprint for the future of telecommunications. teleSys MACH7 solutions will allow Network Equipment Providers and System Integrators to provide the full convergence of services and network architecture using interfaces like::

• Camel and Wireless-IN – Needed to create a virtual home environment for roaming subscribers.
• GSM-MAP and ANSI-41 – Enables interfacing with 2.5G networks for mobility management and service interaction.
• MAP and AIN – Allows IMS access to existing fixed network services.
• SIP – Enables multimedia session control and service management within the IMS.
• Diameter – Facilitates the exchange of subscriber data for AAA purposes subscriber profile management, and service mobility billing and management

teleSys Solutions are used for the following 3G IMS Network Elements:

• Call Session Control Function (CSCF) Node
• Home Subscriber Server (HSS)
• Application Server
• Signaling Gateway
• IM Service Switching Function (IM-SSF) Node
• Radio Network Controller (RNC)
