ITU-T
IMS is a key element in NGN network evolution
o IMS (IP Multimedia Subsystem) is the common control infrastructure for real-time and non-real-time end-to-end multimedia services and any mixture of those
o IMS is designed and standardized by 3GPP to integrate smoothly with existing mobile and fixed networks
o New and existing services (e.g. Presence, Location) and applications can be connected and controlled by IMS through the standardized ISC interface
o By using SIP (Session Initiation Protocol) IMS based services can be accessed from any IP/SIP capable device (UMTS, GPRS, WLAN, wireline users, etc. )

ITU-To No IMS: - repeated vertical integration
- no synergies!o With IMS: - one-time integration
