摘要: Future generation communication systems will provide transparent and seamless user roaming with end-to-end quality of service (QoS) guarantees. As a result, the interoperability various communicating platforms emerges as crucial necessity. Universal mobile telecommunication system (UMTS) wireless local area network (WLAN) convergence network, popular representative interworking paradigm, provides plethora multimedia services to users multimode access capability. Resource allocation call admission control (CAC) are key management functions in order guaranteed QoS efficient resource utilisation. In this paper, dual threshold bandwidth reservation (DTBR), scheme is analysed for loose, tight hybrid coupled network. The strong feature that it based on complete sharing (CS) overall bandwidth, which believed yield high radio utilisation while meeting QoS. performance parameters such throughput, delay, voice data blocking probabilities those coupling schemes.
