method for reducing power consumption in dual band dual mode terminal and the dual band dual mode terminal

摘要

The present invention provides a method for reducing power consumption in a DBDM terminal and a DBDM terminal therefor. The dual-band dual mode (DBDM) terminal includes a modem unit including a first modem for communicating with a WiBro network and a second modem for communicating with a WCDMA network, a battery for supplying power to the modem unit, And when the power of the battery is lower than a power threshold, the first modem enters a low power mode (LPM) mode in which power consumption is minimized by disabling a radio frequency (RF) component included in the modem, Upon receiving information indicating that a WiBro network cell is present from the WCDMA network, enters into an active mode that enables the first modem to enable the RF component. According to the present invention, in a DBDM terminal, two modems can be selectively activated in a terminal according to the power level of a battery, thereby reducing power consumption.
