摘　　要：为控制流量拥塞,提出以在线的各类On-Off型实时可变比特率业务连接的峰值带宽和预期的分组丢失率门限为依据的部分共享型呼叫接纳控制策略。给出呼叫损失概率和分组丢失率的计算方法,分析这些服务质量指标与该策略中可动态调整的控制参数之间的关系,对相关结论给予数学证明或数值验证。In order to control traffic flow congestion, a Call Admission Control（CAC） strategy for resource partial-shared systems with Variable Bit Rate（VBR） services is proposed. It is dependent on the max bandwith and the expired threshold of the cell loss probability online connections of each type of service. An approach of the call blocking probability and the packet loss probability are presented. The relations between QoS indicators and control parameters used in the strategy are analyzed, and some related conclusions are proved mathematically or numerically.
