Overview | Telecom Service Providers | Equipment Manufacturers | Capabilities

The IP Multimedia Subsystem (IMS) is generating renewed interest among network operators because of its ability to provide modular, flexible service delivery, and fast time to market for new services. Designed to work across wireless, wireline, and cable networks, IMS has emerged from being a relatively peripheral standards activity at the 3rd Generation Partnership Project (3GPP) to being the core proposition for the delivery of new and converged IP services.

Many complex factors can influence customer demand for these services, and the trends can be difficult to predict. This dynamic environment of constantly changing usage models and increased device capabilities require the service providers to bring new services to the market rapidly and maintain the agility to scale the ones that sell.

Challenges faced by Service Providers:

• Stagnating subscriber base
  • Global subscriber base growth rate declined 20% in CY 2006-07 *
  • Higher subscriber churn
• ARPU decline
  • Global wireless ARPU dropped by 6.4% in CY 2006-07*.

• Compliance to multitude of standards and evolving specifications
  • Evolving standards
  • Open to interpretation hence differing vendor implementations
• Bridging currently deployed architectures to IMS architectures
  • Migration of existing fixed/wireless non SIP networks to SIP based IP network
• End-to-end performance guarantee
• Network interoperability of IP-based services
• Handling the high signaling and message loads in IMS sessions
