Abstract

A method of wired connection measuring the standby time of a CDMA mobile terminal, connects the CDMA mobile terminal with network emulator, and places them in the network test environment, then measures the standby current, voltage and electric quantity at standby time of the mobile terminal, thereby calculates the standby time of the mobile terminal. This method needs low test environment, and testing is simple and rapidly.

Claims (37)

1. A method for wired connection measuring standby time of a CDMA mobile terminal, comprising:

a) creating a test environment emulating CDMA network and a wired connection measuring condition, wherein the mobile terminal is connected to a network emulator via a wired connection, the network emulator being a base station emulator;

b) measuring an average standby current, a voltage, and an electric quantity at a standby time period of the mobile terminal; and

c) calculating the standby time period T Idle according to parameters of the mobile terminal measured in step b),

wherein in the step c), the equation for measuring standby time T Idle is:

2. The method for wired connection measuring standby time of a CDMA mobile terminal according to claim 1 , wherein the step a) further comprises the following steps:

1) placing the mobile terminal to be measured and the network emulator in a specified environment which is shielded from outer electromagnetic wave;

2) placing the mobile terminal to be measured on a test table made from low electromagnetic loss materials;

3) connecting the radio frequency port of the mobile terminal to be measured with one end of a radio frequency cable of low power consumption whose loss is known, and connecting the other end of the radio frequency cable of low power consumption to the network emulator; and

4) setting the mobile terminal to be measured in a standby work state.

3. The method for wired connection measuring standby time of a CDMA mobile terminal according to claim 2 , wherein, in the step 4), if the mobile terminal to be measured is a flip CDMA hand phone, opening its upper flip to the most extent.

4. The method for wired connection measuring standby time of a CDMA mobile terminal according to claim 2 , wherein, the mobile terminal to be measured is equipped with qualified battery of the mobile terminal.

5. The method for wired connection measuring standby time of a CDMA mobile terminal according to claim 2 , wherein, if the mobile terminal to be measured is a CDMA hand phone, setting the backlight of the hand phone to be measured in closed state or in the darkest state.

6. The method for wired connection measuring standby time of a CDMA mobile terminal according to claim 2 , wherein, placing the CDMA mobile terminal to be measured vertically on the test table made from the low electromagnetic loss materials.

7. The method for wired connection measuring standby time of a CDMA mobile terminal according to claim 1 , wherein the step b) further comprises the following steps:

1) using an external constant voltage power supply as power supply for the mobile terminal to be measured;

2) setting the mobile terminal in standby work mode and keeping it for ΔT Idle time period;

3) obtaining average standby current i Idle during ΔT Idle time period by measuring and calculating.

8. The method for wired connection measuring standby time of a CDMA mobile terminal according to claim 1 , wherein the step b) further comprises the following steps:

1) using a charger of the mobile terminal to be measured to fully charge the qualified battery, and then fully discharging at 0.5 C on a battery tester;

2) recharging the real battery fully with the charger;

3) mounting the fully charged real battery on the battery tester, and discharging at constant current I 0,Idle till automatic power off voltage V t of the mobile terminal to be measured is reached, and recording discharging time as T 0,Idle , then the total discharge of the battery can be I 0,Idle ·T 0,Idle .
