Problems solved by technology
Since the mobile terminal will try to access the cell with the highest priority when it performs cell reselection next time, if the cell with the highest priority is still in a congested state, the mobile terminal will still be unable to access the cell, causing the mobile terminal to If cell reselection cannot be performed smoothly, the mobile terminal will always stay in the original cell with poor signal quality

The present invention relates to a method and a device for accessing a cell. The method comprises the following steps: determining a cell with the highest priority level in a cell list as a target cell when detecting that the signal strength of a currently resident original cell is lower than a first threshold value; transmitting an access request to the target cell; when failing to access the target cell, modifying the priority level of the target cell in the cell list to be a preset level, wherein the priority level of the preset level is lower than the highest priority level; determining the cell with the highest priority level in the cell list as a designated cell; and transmitting the access request to the designated cell. When the cell reselection is performed, the access request is transmitted to the target cell with the highest priority level in the cell list, in order to facilitate access the target cell. According to the solution provided by the present invention, when the cell reselection is performed on a mobile terminal, the mobile terminal can be accessed to the cell with the highest priority level and without congestion, thereby ensuring the signal quality of the mobile terminal.
Description
technical field [0001] The present invention relates to the field of communication technology, and more specifically, to a method and device for accessing a cell. Background technique [0002] Usually, the operator will pre-define the priority level of the cell, so that when the mobile terminal performs cell reselection, it can preferentially select the cell with the highest priority level to reside in, so as to keep the wireless network of the mobile terminal in the best state. After the mobile terminal camps in a certain cell, the mobile terminal will obtain the adjacent cell list in the system message broadcast of the cell to monitor the current cell and the signal changes of the adjacent cell, and according to the adjacent cell table The priority level corresponding to each cell performs cell reselection, thereby ensuring that the mobile terminal always stays in a cell with a better signal. [0003] Since the carrying capacity of each cell is limited, if too many mobile...
