独立专用控制信道的优化配置

Optimization of Stand-Alone Dedicated Control Channel

GSM系统中传递的用户位置更新登记、呼叫接续命令和网络用户鉴权等系统信息是在指派业务信道(TCH)前由独立专用控制信道(SDCCH)来传递的,且TCH资源和SDCCH资源不能相互转换.若信道配置过多,将导致资源浪费.因此,优化SDCCH信道与TCH信道的配置数量,提高资源利用率,是GSM网络优化的长期研究课题.

The GSM system information including the user location updating registration, call-in command, and network user authentication is transmitted through the stand-alone dedicated control channel （SDCCH） before designating the traffic channel （TCH）. Since the TCH resources and SDCCH resources are not mutually transformable,configuration of too many channels will waste resources. Therefore,SD- CCH and TCH configuration optimization and resource exploitation rate improvement have been the long-term research topics for GSM network optimization.
