IMS , the revolution ahead
vision : To make a model that separates the services offered by fixed-line (traditional telcos), mobile (traditional cellular), and converged service providers (cable companies and others who provide triple-play — voice, video, and data — services) from the access networks used to receive those services. … Continue reading IMS , the revolution ahead
Telecommunications convergence – VoIP, PBX and IMS
The signalling protocols migration like from signalling system 7 (SS7) to session initial protocol (SIP) have been taking place in Telco-Industry. Similarly nodes of legacy network like signal transfer point (STP) of legacy network are being migrated to call session control function (CSCF) of IMS that allows the rapid development and deployment of enhanced, revenue-generating multimedia services for fixed, mobile and cable operators. IMS architecture enables operators to seamlessly run a plethora of next-generation converged services over their fixed, mobile and cable networks, achieve a faster time-to-market for new services and have fewer performance bottlenecks.
