What is ICSI (Internet protocol multimedia subsystem)?

ICSI is the framework utilized for conveying IP multimedia administrations. It is a methodology used for conveying Internet services over GPRS. This vision was subsequently updated by 3GPP, 3GPP2 and ETSI TISPAN by needing support of organizations other than GPRS. IMS is not planned to normalize applications, but to access multimedia and voice applications from wireless and wireline terminals, i.e., to make a type of fixed-mobile convergence (FMC).
