摘　　要：针对宽带CDMA移动通信系统的多媒体业务,提出一种基于交叉熵的病毒式移动通信网络链路容量方程构建方法。该方法通过定义病毒式移动通信概念,将视频业务数据转化为话音业务数据,进而构建了多媒体业务下的病毒式移动通信网络链路容量方程,并引入交叉熵概念,仿真并分析了微小区病毒式移动用户进行视频业务的发生概率对网络性能的影响。仿真结果表明,微小区病毒式移动用户进行视频业务的发生概率可达到40%。该结果为病毒式移动通信概念应用于3G及4G CDMA移动通信系统的多媒体业务提供了一种方法。Aiming at the multimedia service in a broadband CDMA mobile communication system, the method of the link capacity equation of a viral communication network based on cross entropy is proposed. This method transforms video service data into voice service data by defining the concept of viral mobile communication. The construction of the link capacity equation of viral communication network of multimedia service, and the concept of cross entropy are introduced. The impact of the probability that mobile users carrying on video service in microcell with viral mobile communication on network performance are simulated and analyzed. The simulation result shows that the possibility of mobile users carrying on video service in mierocell with viral mobile commucation can reach to 40 percent. The analysis results supply a method when applying the concept of viral mobile communication to 3G and 4G CDMA mobile communication systems with multimedia service.
