An Improved Data Scheduling Mechanism of Streaming Media in Mobile Network

The gradual evolution of mobile communication network into 4G is increasingly making the streaming media become a new attractive business. However, the service quality of mobile streaming media is urgent to be improved for better service. The relatively fair data scheduling mechanism, node data scheduling within cell and node data scheduling when switching cells are presented in terms of mobile feature of mobile streaming media nodes. The wireless access point selection for node data scheduling within cell is further researched, and a wireless access point selection mechanism which is suitable for mobile streaming media is provided. The theoretic analysis verifies the fair principle of user service quality for mobile streaming media, and the appropriate data scheduling mechanism improves the reliability of data transmission, which entirely boosts the service ability of system. The simulation test shows that the wireless access point selection mechanism balances the loads of wireless access points to some extent and improves the node number of entire system.
