Abstract:
A method of quantifying the quality of service in a CDMA cellular telephone system comprising:dividing a service area into a total number of locations served by a service area; identifying substantially all locations in a service area having degraded operations, wherein said identifying comprises: determining a level of transmitted signal required from each base station to each location at which signals are expected based upon said received signal level necessary for providing a quality transmission at the location and path loss between the location and each base station; summing the levels of all transmitted signals from each base station; and comparing the sum of the levels of all transmitted signals from each base station to the maximum transmission power of the base station; assigning an average service level value to each location having degraded service to represent a level of service at the location; summing the average service level values of each location in the service area having degraded operations; determining the level of service throughout the service area; determining the ratio of said locations receiving degraded service to said total number of locations served by said service area to obtain a value representing the quality of service for the service area; dividing the sum of the average service level values by the level of service throughout the service area to obtain a value representing the quality of service for the service area.
