OTT RCS
- Need service installation :
open appstore, search app,
pay/download, install
- No necessary installation :
embedded on handset
(download also available)
- Separated communities only
(facebook messenger, skype,
etc.)
- All among compatible
handset
- Needs provisioning setup - Automatic provisioning
- Should open application first
and decide between OTT call
(ie.skype), chat/messenger
(ie.WA, FB messenger).
Some messaging OTT enable
voice services now, but with
very bad QoS.
- Easier service access : user
intuitive placement,
automatic discovery, reliable
services.
- Limited user experiences - Richer user experience
(exchange image/video
during voice call, file transfer,
geo location, shows other
contact communication
capabilities)
- Little to no revenue to
operator (as provided by 3rd
party and carried over the top
of operator network)
- Direct/better revenue from
RCS services
