摘　　要：基于支持多级业务的单码CDMA系统 ,本文设计了一种适合于多级业务接入的两层控制方案。借助于该方案 ,实时业务用户一旦被接纳就立刻进行通信。而非实时数据用户的通信过程要受到呼叫层和突发层双重的控制。这样 ,前者的QoS能够得到保证 ,而后者则可以充分利用网络暂时闲置的信道容量。A new two-level scheme of access control based on a single-code CDMA system supporting multiclass traffic is proposed. By means of this scheme ,the users of real-time traffic transmit their packets without incurring further delay once admitted to the system but the access of nonreal-time data users is regulated at both call level and burst level.Thus,the latter may fully utilize the residual channels without degrading the QoS of the former.
