This paper discusses the joint session scheduling (JOSCH) problem for multimedia services in heterogeneous wireless networks. The adaptive JOSCH based on layer-encoded streaming is designed for real-time multimedia service simultaneously transmitted by several heterogeneous radio access technologies (RATs). Considering the layered characteristics of the layer-encoded streaming, an adaptive JOSCH mechanism, along with the supporting network architecture, is designed to make efficient usage of the heterogeneous wireless resources and adapt to the dynamic network changes. Simulation results show that the adaptive JOSCH is effective in guaranteeing the QoS of multimedia and maintaining a high transmitting adaptability in multi-RATs environment.
