| 摘 要： | 首先,分析在双卡双待系统中电路交换/分组交换（circuit switching/packet switching,CS/PS）接入任务不能在辅卡上执行的冲突问题,设计了主辅卡倒换过程。然后,详细介绍主辅卡倒换过程的设计原则,设计辅卡收到CS接入请求时触发主辅卡倒换过程的实现流程图。最后,实现了在辅卡上发起接入任务时,将辅卡设置为主卡后再执行任务,保证接入业务的正常进行。此研究对双卡双待系统中处理对辅卡发起的接入任务具有重要意义。

| Abstract: | This paper introduces the dual-card-dual-standby system and analyses the conflict that the secondary card can＇ t deal with the CS/PS services in dual-card-dual-standby system firstly. Then it provides the switching of the primary and secondary card. Finally, it details the implementing principles and provides the implementing flow chart of the switching process of primary and secondary cards which is triggered by CS services on secondary- card. This process solves the prob- lem that the secondary card can＇ t deal with the CS/PS services. |
