  • 9. Telecoms Technologies – The Emerging Picture IMS – Operator Benefits Frost & Sullivan, Jan 2008: "The key factors propelling the carrier adoption of IMS include: - lower capital and operational expenditures, - shorter new product introduction (NPI), - flexibility in creating new 'combinational services’ - higher ARPU) due to the advent of new services.” “Providing the capability to work with different equipment manufacturers will be one of the main challenges.” 16 Telecoms Technologies – The Emerging Picture IMS – Benefits to the User User Benefits • “New” Services • Personalisation • Access anywhere • Security • Blending of services • Ease of use 17 9
  • 10. Telecoms Technologies – The Emerging Picture IMS – The Market? May 2008 (from NXTComm) “For now conversations with service providers, equipment manufacturers and chip/board vendors seem to show a long-awaited upturn in real-world IMS deployments – though projects remain mostly experimental and small-scale in nature. Sources consistently pointed to 2006-2007 as the low point for the IMS ‘hype cycle’, with carriers finding it hard to justify the expense or complexity of taking a wholesale plunge into IMS.” 18 Fixed Access All material is Copyright © Informa Telecoms & Media 2001-2008 10
