    • 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.
    • 披露了跨层优化方法,其中关于无线环境中的大量动态变化的信息被共享并且跨层优化被实现和抽象层组件。 通过使用从具有传输层和网络层的第一层提供的服务信息以及比数据链路层低的第二层来实现第一层和第二层的优化的多媒体传输层操作方法。 操作方法包括向第二层提供服务信息进行处理和处理的向上抽象步骤,向多媒体传输层提供服务信息,并向下抽象步骤提供从多媒体传输层提供的指示信息处理和处理的服务信息提供给第二层。 因此,有利的是,所有层都共享关于无线环境中的许多动态变化的不同信息,并且可以控制各种信息以允许更有效地确保QoS的传输。
