SYSTEM AND METHOD FOR DETERMINING WHEN TO EXIT AN EXISTING WIRELESS COMMUNICATIONS COVERAGE NETWORK

摘要

A system and a method are presented for determining when to exit an existing wireless communications coverage network. The system comprising a calculator circuit (300) for sampling received input power levels (702); comparing the the received input power level samples to a predetermined baseline threshold value (704); adjusting an indicator responsive to the received input power level samples compared to the predetermined baseline threshold value (707); setting a terminal condition indicating when the wireless communications device should exit the existing wireless communications coverage network (709); and exiting the existing coverage network based on a comparison of the indicator to the terminal condition (711, 714).
