Standby processing method and device for mobile terminal

Abstract

The disclosed device for standby process of mobile terminal comprises a baseband processor for calling, a MPU to send correction signal and wake-up signal to processor periodically. Wherein, the processor corrects self clock with correction signal from MPU on standby calling; it closes self inner clock once calling end; when receiving wake-up signal, it start up self clock for calling. This invention can reduce terminal power consumption and prolongs standby time.

Description

technical field [0001] The present invention relates to a power consumption control technology of a mobile terminal, in particular to a mobile terminal standby processing method and device for reducing power consumption. Background technique [0002] In order to support complex baseband calculations and high-speed data services, as well as follow up with changing standards, current mobile terminals generally use high-speed DSP processors as baseband processors. A high-speed DSP processor usually includes three working states, namely: running state, light sleep state, and deep sleep state. The power consumption control of the DSP processor whose clock frequency is above 300MHZ is a technical difficulty. [0003] When the mobile terminal is in standby mode, due to the need to maintain a synchronized clock with the air, the DSP processor of the mobile terminal will perform paging at regular intervals to receive paging information from the cell, and paging takes a period of tim...

AI Technical Summary

Problems solved by technology

In the light sleep state, the power consumption of the high-speed DSP processor will be relatively high, for example, up to tens or even hundreds of milliwatts, so that the standby power consumption of the entire mobile terminal is relatively high, which cannot meet the needs of general commercial mobile terminals.
