here is a growing demand for efficient multimedia streaming applications over the Internet and next generation mobile networks. Multimedia streaming services are receiving considerable interest in the mobile network business. As communication technology is being developed, the user demand for multimedia services raises. The third generation (3G) mobile systems are designed to further enhance the communication by providing high data rates of the order of 2 Mbps. High Speed Downlink Packet Access (HSDPA) is an enhancement to 3G networks that supports data rates of several Mbit/s, making it suitable for applications like multimedia, in addition to traditional services like voice call. Services like person-to-person two way video calls or one way video calls, aim to improve person-to-person communication. Entertainment services like gaming, video streaming of a movie, movie trailers or video clips are also supported in 3G. Many more of such services are possible due to the augmented data rates supported by the 3G networks and because of the support for Quality of Service (QoS) differentiation in order to efficiently deliver required quality for different types of services. This paper present congestion control schemes that are suitable for multimedia flows. The problem is that packet losses, during bad radio conditions in 3G, not only degrade the multimedia quality, but render the current congestion control algorithms as inefficient. This paper proposed a solution that integrated the congestion control schemes with a priority based multimedia packets to increase the speed of multimedia data and reduce the packet loss that is developed due to congestion in networks
