CROSS-LAYER OPTIMIZATION METHOD IN A MULTIMEDIA TRANSMISSION SYSTEM, AND AN ABSTRACTION LAYER COMPONENT FOR THE SAME

摘要

Disclosed are cross-layer optimization method where information about lots of dynamic changes in wireless environment is shared and cross-layer optimization is implemented and abstraction layer component. Multimedia transmission layer operating method where optimization of first layer and second layer is implemented by using service information provided from first layer having transmission layer and network layer and second layer lower than datalink layer. The operating method includes upward abstraction step where service information provided to second layer is processed and processed service information is provided to multimedia transmission layer and downward abstraction step where indication information provided from multimedia transmission layer is processed and processed service information is provided to second layer. Consequently, there is advantage that all layers share diverse information about lots of dynamic changes in wireless environment, and the diverse information can be controlled to allow transmission where QoS is ensured more effectively.
