WCDMA is an important air interface technologies for wireless networks. As WCDMA based cellular networks fully developed, the current point-to-point links will evolve to an IP-based Radio Access Network (RAN).This Paper present a review of congestion control mechanism using Router control, channel control and admission control method for IP-RAN on WCDMA cellular network. The Router control mechanism uses the features of WCDMA networks using active Queue Management technique to reduce delay and to minimize the correlated losses. The Random Early Detection Active Queue Management scheme (REDAQM) is to be realized for the router control for data transmission over the radio network using routers as the channel.
