ormal network operation. Base Station Hardware and Software Version Management Base station hardware (HW) and software (SW) version management checks the HW and SW update status in the network, which is vital for optimum network wide performance. Both HW and SW versions can be audited with similar procedures, where the base station configuration files are transferred directly from the base stations by FTP and then the required information is gathered from these files. Radio Parameter Audit The radio parameter audit verifies that RAN parameters implemented on the network are set consistently in all objects and follow the default parameter set. The radio parameter audit is done to check the consistency of radio parameters by comparing the actual values and default recommended values defined for network objects. Typically in prelaunch networks the actual parameter values have the same value for all objects. The actual values should also follow the recommended parameter values. The radio parameter audit is performed to check the majority of parameters in RNC, WBTS, WCEL (WCDMA cell), ADJS (intrafrequency adjacency), ADJI (interfrequency adjacency), ADJG (intrasystem [WCDMA GSM] adjacency), FMCS (measurement control set for intrafrequency adjacency), FMCI (measurement control set for interfrequency adjacency), FMCG (measurement control set for intrasystem [WCDMA GSM] adjacency), HOPS (handover control parameter set for intrafrequency adjacency), HOPI (handover control parameter set for interfrequency adjacency) and HOPG (handover control parameter set for intrasystem [WCDMA GSM] adjacency) object classes. Parameter Consistency Check Parameter consistency checks are done to verify consistency of the RAN parameters. Most RAN param- eters are set to default values in prelaunch networks; later multiple templates can be defined for different types of cells. The default settings can be checked outside Nokia operations solutions system (OSS) by exporting the parameter information. Default parameters should be checked regular
