The IP Multimedia Subsystem (IMS) is the heart of all next-generation networks.
EVISTEL offer solutions that avail the new capacities brought by IMS technologies, and that ease the migration of all legacy services to IMS.
Next-generation networks will be full IP based, with communications controled by an IMS network. IMS provides new capabilities for new services like RCS (Rich Communication Services), but the technology is complex and migration of existing services to this new infrastructure can be a real challenge.
For more than 10 years, EVISTEL has invested to master IMS technologies. All EVISTEL solutions are now IMS compatible, and we have developped specific solutions for IMS:
- new services that harness IMS technologies: RCS suite for next generation messaging and advanec Business-to-customers communication, WiFi Calling to extend legacy mobile networks with WiFi hotspots
- gateways and controller to bring legacy services to IMS world: IP-SM-GW for existing messagng services (SMS…), SIP controler for all IN and voice services.
RCS is the standard of the next-generation messaging. RCS creates new opprotunities for Business-to-Customer messaging with rich contents, secured messages, interactive chatbots…
