摘　　要：无线资源管理中的呼叫允许控制是TD-SCDMA的重要组成部分,性能优良的呼叫允许控制策略可以尽可能高地提高网络资源利用率。对于单纯的CDMA系统,呼叫允许控制必须依据目标信干比保证所有激活用户的服务质量。然而,TD-SCDMA系统的呼叫允许控制与其时隙分配方法有密切的关系,考虑了两种呼叫允许控制方案并给出仿真结果。Call admission control of wireless resource management is very important for TD-SCDMA. The excellent call admission control scheme can improve the resource utilization as highly as possible. As with pure CDMAschemes, the Call Admission Control mechanism must guarantee the quality of all active calls in terms of Signal-to-Interference Ratio. However, the problem of admission control is strictly related to time slot assignment scheme for TD-SCDMA. Two classes of call admission control scheme are considered and simulation results is also given.
