New mobile telecommunication systems provide various features for their users. Different infrastructures, from the first generation up to now, tried to increase the quantity and quality of the service for mobile subscribers. Analog techniques in primary mobile networks were just for providing voice calls to users. But nowadays, in addition to this task, users can send and receive messages, share photos, connect to each other by video, etc. All these services need large bandwidths as a principle parameter to send and receive huge data packets. In recent years, users are being attracted to third generation networks. These networks bring about high bit rate of multimedia transfer like video, image and voice. This capability of sending multimedia data is the outstanding feature of these networks. In third generation networks which are developing, new technology of HSPA attracts the operators to increase the network capacity. This standard is deployed on one-hop cellular mobile networks and provides high data rate in wireless channels. The most important features which are distinguished from former standards are gathering channel status, fast scheduling between users and adaptive modulation and coding. These features are working based on one useful feature which helps the network to query the channel status of each user at each time slot. This feature monitors the network as fast as possible and brings a good metric to decide to serve which user among the users group. In this thesis, we proposed a fair scheduling scheme which provides high quality of received data for real-time video service over HSDPA networks. This research is performed based on basic MPEG video standard in dir=ltr Keywords: HSDPA Networks, Virtual Queue, Lyapunov Drift, Fair Scheduling
