SYSTEM AND METHOD OF DETERMINING STANDBY TIME FOR MOBILE STATIONS
First Claim
1. A method of determining standby time for a mobile station, the method comprising:
- generating a simulated battery voltage for the mobile station;
measuring current consumption of the mobile station in standby mode using the simulated battery voltage;
determining an available battery capacity of a battery for the mobile station; and
determining a standby time for the mobile station based on the current consumption and the available battery capacity, wherein the measuring of the current consumption is performed for a time period less than the standby time of the mobile station.

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.
