Example Embodiment

[0018] The purpose of the present invention is to provide a power saving method for a wireless terminal with CMMB module function.

[0019] In the present invention, it is first necessary to ensure that the CMMB chip must have the functions of controlling its reset and power-on enable on the hardware. Make the baseband chip controllable under CMMB chip work and low power consumption mode.

[0020] Realize that the PC-side driver uses different methods to write the firmware to the wireless terminal CMMB according to different situations. After the firmware is downloaded on the wireless terminal side, the CMMB module can realize power-saving and low-power operation.

[0021] Then every time the PC starts / stops the CMMB function, it performs corresponding power-on and power-saving operations according to the wireless terminal side chip status. According to different situations, there is no need to download the firmware through the PC side each time, which not only saves download time bu...

Abstract

The invention provides an electricity-saving method of a wireless terminal; the characteristics are as follows: CMMB chip of the wireless terminal has function of controlling reset and power-up on the hardware, the baseband chip is controllable under the circumstances that the CMMB chip works and is in low power mode, a PC-side driver writes firmware for wireless terminal CMMB through different methods according to different situations, after the wireless terminal side downloads firmware, electricity-saving low-power-consumption operation is realized for CMMB module; after PC starts/stops CMMB function, corresponding power-up and electricity-saving operation is conducted according to wireless terminal side chip situation. In this way, the invention not only can save downloading time, but also can reduce the power consumption of the wireless terminal under the circumstances that the CMMB function is not used. The battery power of the user is saved as much as possible, the play time of the terminal is extended, and the PC mobility is better.

Description

technical field [0001] The present invention relates to the field of wireless communication, and more particularly, to a method for saving power of a wireless terminal. Background technique [0002] The current CMMB chip needs to re-download the firmware program every time the power is turned on again after power-off, and the data card with the CMMB function module prevents the PC-side software from But when running, the CMMB chip is in the power-up state, which not only consumes a lot of power when the data card is running and in standby, but also causes the computer users who use the network card, especially the notebook computer users The computer standby time is shortened. The CMMB chip of the data card is always in the power-on state because once the CMMB chip is powered off and restarted, it needs to download its firmware program from the PC side software. Downloading the firmware program is not only time-consuming, but also if the CMMB chip repeatedly enters the low ...
