5 Why IMS? IP Multimedia Subsystem (IMS) will be at the core of converged networks For every type of network operator Impacting everyday aspects of business Traditional PLMN IMS Traditional PSTN Wireless-BB (3G, WiFi, WiMax) Fixed-BB (DSL, cable, FTTP) IMS is the key enabler to accelerate network convergence and flexible service delivery Mobile operators are implementing cost-effective network evolutions in preparation for IMS while trialing pre-ims Fixed operators are deploying SIP-based architectures on costeffective IP infrastructures, evolving naturally to IMS 5
