Abstract

The invention discloses a power saving method and device for a multi-mode terminal. Wherein, the method includes: using the sleep mode and wake-up mode of the DBB of the multi-mode terminal, controlling and outputting the state value CLK1_EN / CLK2_EN of PWRCTRL1 / PWRCTRL2; using CLK1 / CLK2 and CLK1_EN / CLK2_EN, controlling the RF TRX to output CLK1_OUT / CLK2_OUT; Send CLK1_OUT / CLK2_OUT to the MODEM and SOC / BUS / Peripheral of DBB as the high-speed clock source of the multi-mode terminal standby state and working state. Through the present invention, the wake-up time of the modem subsystem can be shortened and the sleep time can be lengthened for the multi-mode terminal within one DRX cycle, thereby achieving the effect of reducing standby power consumption.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for saving power of a multi-mode terminal. Background technique [0002] With the advent of the 4G era, LTE (Long Term Evolution, long-term evolution) broadband high-speed data The business has great transmission advantages, and at the same time it can maintain the excellent voice service advantages of the existing 2G / 3G (especially 2G). Using this advanced technology can achieve the effect of less investment and less network operating costs. Since the multi-mode dual-standby / dual-pass can achieve such a goal, dual-standby / dual-pass will be the preferred operation mode of mobile network communication operators. However, one of the biggest bottlenecks of this mode at present is the problem of standby power consumption. [0003] Aiming at the problem of how to reduce the large standby power consumption of multi-mode dual-standby / dual-pass terminals in related...
