| 摘 要： | 定义了参数PD近似描述自适应业务的服务质量,并使用M/M/m(m)模型对使用自适应QoS业务时的小区容量进行了数值分析,获得了自适应业务的QoS和呼损、系统容量以及系统效率的互换关系,表明使用自适应业务可以通过主动降低其QoS而有效地增加网络容量和系统效率,并降低呼损率.

| Abstract: | Adaptive QoS service in mobile network can improve the system capacity by decreasing its source rate when the network is busy. This merit is especially important when broadband services are provided. A new parameter P D is defined to approximately describe the QoS of adaptive service, and the cell capacity with adaptive service is analyzed using a M/M/m(m) queuing model. The trade off relationship between the QoS of adaptive service and call block ratio, system capacity, system efficiency is illustrated. The numeric result shows that using adaptive QoS service, the capacity and efficiency can be effectively improved and the call block ratio can be largely reduced. |
