From a User Perspective,
IMS has Unique Advantages
• IMS is the best platform to realize multiparty services:
Presence texting: from one-to-many to many-to-many (chatting)
Voice: from one-to-many voice messaging to Push-to-talk (real time) to
Voice conferencing
• IMS is the best platform to realise converged services:
Collaborative working / multiple sessions
Multiparty gaming
Rich voice: Voice with picture/video streams, Video Call combined with
data services.
