摘要
为了实现为不同接入等级用户提供不同紧急程度的接入服务,保证高优先级用户的优先接入,TD-SCDMA系统提供了接入等级控制机制。通过使用接入等级、接入服务等级、坚持度检查、UpPCH子信道分配等机制,TD-SCDMA系统实现了用户的接入优先级控制。本文从理论和实际的角度对此机制进行了分析,并进行了仿真验证,仿真结果表明该机制能有效实现不同优先级用户的接入优先级控制。
In order to provide differentiated emergency level of access services to users with different access priorities to ensure the access of high-priority users, TD-SCDMA system introduces class- based access control mechanism, which is realized through the application of access class, access service class, adherence degree examination, UpPCH subchannel allocation system. In this paper, this mechanism is analyzed from the theoretical and practical perspective and is verified by simulation. The simulation results show that the mechanism can realize access control according to the priority of users effectively.
