This paper implements the design of TD-SCDMA system service analysis function on the base of decoding and protocol statistical function. Aiming at the features of TD-SCDMA system?s interface protocol stacks

it extracts the parameters respectively related to the wireless resource management

mobile management and calling management from the interfaces? signaling. After processing the network parameters

it will get the basestation subsystem?s complete statistical data. It supplies the data for establishing the optimi-zation methods of the wireless network resources

it is propitious to resolving the questions

such as network overcast

signaling channel congestion

wireless parameters illogically settings

etc in the net-work optimization.
