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 the 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 sleep state of low power consumption or wake it up from the sleep state respectively. Frequent sleep and wake-up of each layer unit increases the power consumption of the mobile terminal, and further sets the sleep time threshold. When the mobile terminal is in an idle state, calculate the shortest time it needs between now and the last task execution If the time is greater than the set sleep time threshold, the power saving control unit controls the application layer unit, the high 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 performed at this time, and then it is decided whether to wake up the high-level protocol...

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 mobile terminals, in particular to a mobile terminal and a power saving method thereof. Background technique [0002] UE has two basic operation modes: IDLE (idle) mode and connection mode. After power-on, the UE stays in IDLE mode. The behavior of the UE in idle mode can be subdivided into PLMN (Public Land Mobile Network) selection and reselection, cell selection and reselection, and location registration. When the UE is turned on, it should first select a PLMN. When a PLMN is selected, it starts to select a cell belonging to this PLMN. When such a cell is found, the information of the adjacent cell can be known from the system information broadcast, so that the UE can be in Select a cell with the best signal among all these cells to stay in. Immediately afterwards, the UE will initiate a location registration process, and if successful, the UE will successfully camp in this cell....
