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,SDCCH and TCH configuration optimization and resource exploitation rate improvement have been the long-term research topics for GSM network optimization.

Key words: SDCCH, TCH, authentication, waste of resources
