Abstract: A mobile terminal and a method are provided for power saving. The mobile terminal monitors changes of data on a UART bus, acquires current operating states of a Bluetooth chip and a main control chip on the mobile terminal, and when detecting that there is no data on the UART bus, the main control chip controls a Bluetooth module to enter into a power saving mode. By adopting the technical scheme described, once it is detected that there is no data on the bus, the Bluetooth module will be enabled to enter into a state of power saving mode immediately, which ensures that the Bluetooth module is always in the state of power saving mode when there is no service ongoing, thereby increasing the standby time of the mobile terminal to the maximum extent, and improving the level of the user experience.

Abstract: The present invention provides a mobile terminal and a method for dormancy of a mobile broadcast business management system (MBBMS) module in the mobile terminal. The method comprises: before the MBBMS module enters into dormancy, extracting working state information and firmware information of the MBBMS module and storing the working state information and firmware information into a non-volatile memory in a form of file; and after the MBBMS module is awakened, reading the working state information and firmware information from the non-volatile memory, configuring the MBBMS module based on the working state information and firmware information and restoring working context of the MBBMS module.
