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