基于QoS的WCDMA网络编码容量增强
QoS Based Capacity Enhancement for WCDMA Network with Coding Scheme
摘要：
基于宽带码分多址（WCDMA）的第三代及更高级别的蜂窝移动无线网络有望为移动用户提供各种各样的多媒体服务，并保证服务质量。为了满足这些网络的不同服务质量要求，需要新的无线电资源管理策略，以便利用编码方案有效地利用网络资源。呼叫接纳控制（CAC）是无线网络中保证服务质量要求和增强网络弹性的重要组成部分。为了在资源利用率和服务质量提供之间取得更好的平衡，本文讨论了采用卷积编码方案的WCDMA网络容量增强，并与分组编码和无编码方案进行了比较。该网络模型适用于具有不同数据率的实时（RT）和非实时（NRT）业务。仿真结果表明，使用卷积码的网络在容量增强和语音和视频服务的QoS方面的有效性。
英文摘要：
The wide-band code division multiple access (WCDMA) based 3G and beyond cellular mobile wireless networks are expected to provide a diverse range of multimedia services to mobile users with guaranteed quality of service (QoS). To serve diverse quality of service requirements of these networks it necessitates new radio resource management strategies for effective utilization of network resources with coding schemes. Call admission control (CAC) is a significant component in wireless networks to guarantee quality of service requirements and also to enhance the network resilience. In this paper capacity enhancement for WCDMA network with convolutional coding scheme is discussed and compared with block code and without coding scheme to achieve a better balance between resource utilization and quality of service provisioning. The model of this network is valid for the real-time (RT) and non-real-time (NRT) services having different data rate. Simulation results demonstrate the effectiveness of the network using convolutional code in terms of capacity enhancement and QoS of the voice and video services.
