Abstract:
A method for testing handover in mobile telephone networks, comprising the steps of:passing a test mobile through relevant traffic routes,transmitting a radio signal from the test mobile while passing through the relevant traffic routes,registering a position of the test mobile while passing through the relevant traffic routes,measuring synchronously at actual base stations plural signal strengths of the radio signal received from the test mobile while passing through the relevant traffic routes,storing in a measurement database the plural signal strengths from the actual base stations with respect to a time and respective registered position of the test mobile so that an unambiguous relationship between signal strengths, time and position is obtained,playing back the time and respective registered positions of a sub-set of the plural signal strengths from the measurement database,varying handover parameters, andtesting how handover between a simulated mobile and the actual base stations would occur by using the varied handover parameters and the time and respective registered positions played back from the measurement database.
