拨打手机时种种回应的理论分析

Theoretical Analysis on Various Responses of Mobilephone Calling

手机移动通信是当前重要的通信方式之一,在硬件和无线网络平台搭建好的前提下,拨打手机时不一定能实现正常的通话,由于网络覆盖、信道忙闲、手机状态等原因,往往会得到诸如不在服务区、拨打的手机已关机、正在通话中、无人接听、网络忙、无法接通等种种回应。从网络搭建、信道分配、手机入网的角度理解和剖析手机通话的机理,可以避开影响手机不能正常通话的诸多因素,提高手机的使用效率。

Mobile-phone communication is an important communication mode,and with the building-up of hardware and wireless network platform building,the mobile-phone couldn＇t surely achieve normal calling,and also due to the network coverage,busy or idle channel,mobile-phone state,etc.,various responses might be received,such as that the mobile phone is not in service area,not powered,or someone is on the phone,nobody answers,network is busy.From the network structures,channel allocation and mobile-phone access the mobile phone communication mechanism is analyzed and understood,thus avoid various influences or normal mobile-phone communication and improve mobile phone＇s use efficiency.
