Embodiment 1

[0031] This embodiment provides a method for saving power for a mobile terminal. The mobile terminal includes an initially empty cell list, and the cells that provide communication services for the mobile terminal are base station serving cells. The cell is an adjacent cell, and users use mobile terminals at home, such as figure 1 shown, including the following steps:

[0032] Step 101, taking the cell with the strongest signal strength among the cells near the mobile terminal as the serving cell of the base station;

[0033] In this step, the mobile terminal will send a request to the base station, search for the signal strength of nearby cells, and compare them to obtain the cell with the strongest signal strength, and stay in this cell to use the communication service provided by this cell.

[0034] Specifically, assuming that there are four cells A, B, C, and D in the vicinity of the mobile terminal, the cell that provides communication services for the mobile terminal is...

Embodiment 2

[0050] This embodiment provides a method for saving power of a mobile terminal, see figure 1 As shown, the difference between this embodiment and the method for saving power in Embodiment 1 is that: in the state of the power saving mode, the mobile terminal judges whether the signal strength of the serving cell of the base station is less than a threshold, and if so, returns to step 101, If not, the mobile terminal continues to maintain the power saving mode.

[0051] That is, in order to provide users with better communication services, in the power-saving mode, it is necessary to measure the signal strength of the base station serving cell currently serving the mobile terminal, that is, the size of the B area, if it is less than a set threshold, If calculated by the number of grids indicated by the signal strength, if the number is less than two grids, the mobile terminal will exit the power saving mode and re-search for a new cell with the strongest signal strength.

Abstract

The invention discloses a mobile terminal and a method for saving the electric quantity of the mobile terminal. The mobile terminal comprises a cell list, which is empty initially; a cell for providing a communication service for the mobile terminal is a base station service cell; and cells near the mobile terminal, except the base station service cell, are neighbour cells. The method comprises the following steps of: taking a cell having the highest signal strength in the cells near the mobile terminal as the base station service cell; and judging whether the base station service cell is in the cell list or not, if so, ending the process after the mobile terminal starts a power-saving mode, if not, starting a timer, storing the base station service cell in the cell list and starting the power-saving mode by the mobile terminal when the time of the timer reaches a duration, and returning to the first step if the time of the timer does not reach the duration. By means of the scheme, whether the signal of the base station service cell is steady or not can be judged; therefore, the mobile terminal enters the power-saving mode conditionally; a lot of electric quantity of the mobile terminal can be saved; and the radiation generation time can also be reduced.

Description

technical field [0001] The invention relates to a mobile terminal and a method for saving power. Background technique [0002] With the development of mobile communications, there are more and more third-party applications on mobile terminals. While satisfying user experience, mobile terminals will often send cell search signals to base stations in the background in order to provide users with a good communication environment. The mobile terminal is enabled to obtain a cell with better signal strength and reside in the cell, thereby providing better communication services for the mobile terminal. [0003] However, the mobile terminal often sends requests to the base station, and will continue to search for new cells with better signal strength even in the standby state, which consumes a lot of power for the mobile terminal and generates more radiation due to frequent searches. Contents of the invention [0004] The technical problem to be solved by the present invention i...
