System and method of determining standby time for mobile stations
First Claim
1. A method of determining a standby time of a mobile station, the method comprising:
- measuring a first array of current measurement data points covering a transmit event of the mobile station in a standby mode, the standby mode comprising a transmit mode and a receive mode, the mobile station powered by a battery having an available battery capacity, the measuring being triggered by the transmit event; and
providing the standby time based on a transmit event number per time unit, a transmit capacity per time unit, a receive capacity per time unit, and the available battery capacity.

Abstract
A method and system for determining standby time for a mobile station uses a battery simulator, a base station emulator, a computer to control the test equipment and MSUT for testing a mobile station. The computer includes a module for determining a radio off battery voltage, a module for deriving a battery capacity in dependence upon the radio off battery voltage, a module for measuring battery capacity usage in a predetermined time while the mobile station is in standby mode and a module for determining a standby time for the mobile station in dependence upon the battery capacity and the battery capacity usage, where the predetermined time is less than the standby time.
