摘要： 提出了3G系统中软切换双队列机制的多业务接入控制策略,对不同业务给予不同的优先权,根据网络的不同状态控制语音或数据切换呼叫、语音或数据新呼叫入网;尤其采用软切换双队列机制,保证了有用的虚假切换请求不丢失,从而有效降低切换呼叫的切换失败概率.实验结果表明,该方法硬件实现简单并能动态分配移动通信网络资源,有效地保证移动通信网络中切换业务的服务质量;该接入控制策略具有切换呼叫等待处理时间短,切换失败概率低等特点.

关键词: 软切换, 优先权, 切换呼叫, 多业务, 双队列

Abstract: An approach to call access control based on soft handoff/double queue for multi-class traffic in 3G systems is proposed to give different priorities in accordance to different traffic. The different calls are controlled to enter into the networks according to different network conditions. And, especially, a soft-handoff/double queue model is used to ensure that the useful false soft-handoff requests not to be lost, so as to decrease the soft-handoff failure probabilities. Experimental results showed that the control model can allocate bandwidth dynamically and utilized network resource effectively and be realized easily on hardware to ensure effectively the QoS of different soft-handoff traffic. It has advantages of low soft-handoff call drop ratio and shorter time for waiting.
