Problems solved by technology

[0010] How to ensure that the terminal does not miss all the downlink information sent by the network side that should be received, and at the same time save its power according to the characteristics of the tasks that different functional modules in the mobile terminal need to complete. There is no effective solution in the prior art.

Embodiment Construction

[0044]The core of the present invention is to set a power saving control unit in the mobile terminal to control the application layer unit, the high-level protocol unit and the physical layer unit to enter the low-power sleep state or wake them from the sleep state respectively, in order to avoid task comparison in the mobile terminal Under frequent conditions, the power consumption of the mobile terminal of each layer unit is continuously increased, and the sleep time threshold is further set. When the mobile terminal is in an idle state, calculate the shortest time required from now to the most recent task execution If the time is greater than the set sleep time threshold, the power saving control unit controls the application layer unit, the higher layer protocol unit and the physical layer unit to enter a low-power sleep state. When the task execution time is reached, the physical layer unit is first awakened to execute the task that needs to be executed at that moment, and th...

Abstract

The invention discloses one kind of mobile terminal, in which, the application-layer unit, physical layer modules and the upper unit can be stopped into a state of dormancy or started again from the state of dormancy through installing a efficient internal control unit, a mandate-time calculating unit and a timer module. The invention also discloses a method for saving energy for a mobile terminal, in which, it achieves the shortest time needed Ti from now on to the recent implementation of tasks, and stops the terminal application layer, physical layer and the upper layer of the mobile terminal into a state of dormancy when the mobile terminal is in a free state. When the time of Ti arrives, it starts the physical layer to implement its task from the state of dormancy and determines whether to start the upper layer from state of dormancy or not according to the implementation of the physical layer.

Description

Technical field [0001] The invention relates to the technical field of power management in a mobile terminal, in particular to a mobile terminal and a method for saving power. Background technique [0002] UE has two basic operating modes: IDLE (idle) mode and connected mode. After power-on, the UE stays in IDLE mode. The behavior of UE in idle mode can be subdivided into PLMN (Public Land Mobile Communication Network) selection and reselection, cell selection and reselection, and location registration. When the UE is powered on, it should first select a PLMN. When a PLMN is selected, it starts to select the cell belonging to this PLMN. When such a cell is found, the information of neighboring cells can be known from the system information broadcast, so that the UE can Choose a cell with the best signal among all these cells to stay. Immediately afterwards, the UE will initiate a location registration process, and after success, the UE will successfully camp in this cell. There a...
