摘　　要：本文讨论了一种用于分组话音／数据综合的混合多址协议，该协议是固定分配与随机访问的混合，并且赋予话音分组优先传输权，从而保证了无重传话音分组有较小的丢失概率。本文进行了详细的理论分析，并得出了性能比较特性，所得结果认为这是一个兼顾话音／数据综合的较好协议，且具有一定的灵活性。This paper discusses a protocol which is suitable for packeted voice/data integration in packet satellite system.It is a hybrid protocol combined fix allocation with random allocation.In order to ensure a smaller packet drop probability of unretransmission voice packet,it gives the voice packet a priority transmission.A theoretical analysis has been carried out and some comparision characteristics have been obtained.Consequently the protocol is a better protocol for packeted voice/data integration and it has some flexibilty.
