Abstract:
A method for testing forward power control optimization in a PCS CDMA system, said method comprising the steps of:(i) establishing a test laboratory environment to simulate a channel change which occurs in a live radio environment; (ii) simulating a channel change by generating a sinusoid as directed by a base station manager (BSM); (iii) simulating a shadowing and noise contribution to said channel change by determining a respective amplitude value and a cycle value of said generated sinusoid, such that the ratio of energy per chip to noise EcIOâ€ƒof a mobile station changes within predetermined upper and lower bounds; (iv) selecting by a base station manager a particular combination of forward parameter values from among a set of combinations of forward parameter values as system values for making a test call; (v) making the test call using said selected combination of forward parameters; (vi) starting by a data collection platform(DCP) and a mobile diagnostic monitor (MDM) data logging to collect data for said test call including forward frame error rate, a reverse frame error rate, an average Ec/Io and an average digital gain; (vii) stopping data logging after a predetermined time period; (viii) storing said collected data for said combination of forward parameters; (ix) setting another combination of forward parameters, not previously set, from among said set of combinations of forward parameters; (x) when it is determined that there is another combination of parameters to be set, returning to step (v); (xi) selecting an optimal combination of forward parameters from among said set of combinations of forward parameters by comparing collected data for each of said combinations of forward parameters; and (xii) setting parameters in said base transceiver station corresponding to said selected optimal combination.
