Problems solved by technology

However, the carrying capacity of each cell is limited. If there are too many mobile terminals residing in a cell with the best signal quality, then the cell will be congested, which affects the inability of the mobile terminals residing in the cell. To carry out normal business, and it will also cause other mobile terminals to be unable to camp in the cell

Embodiment Construction

[0079] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0080] figure 1 It is a flow chart of a cell reselection method shown according to an exemplary embodiment. Such as figure 1 As shown, the cell reselection method provided by the present disclosure can avoid cell congestion, so as to ensure the service quality of the cell. The method includes the following steps.

[0081] In step S11, when it is detected that the signal strength of the origi...

Abstract

The invention relates to a cell reselection method and device. The method includes the steps of confirming cells, with the signal intensity larger than a second threshold value, in a cell list when detecting that the signal intensity of the current resident existing cell is lower than a first threshold value, randomly selecting one cell as a target cell from the cells with the signal intensity larger than the second threshold value when at least two cells with the signal intensity larger than the second threshold value are included in the cell list, and sending an access request to the target cell. According to the scheme, when cell reselection is conducted at mobile terminals, each mobile terminal can randomly select the cells with the signal intensity larger than the second threshold value, and therefore the situation that when all the mobile terminals select the cells with the best signal quality, cell congestion happens can be avoided.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a cell reselection method and device. Background technique [0002] After the mobile terminal camps in the cell, the mobile terminal will obtain the adjacent cell list in the system message broadcast of the cell to monitor the signal changes of the cell currently camped on and the adjacent cell, so as to facilitate cell reselection and ensure mobile The terminal always stays in the cell with better signal. [0003] When the mobile terminal performs cell reselection, the mobile terminal will preferentially select the cell with the best signal quality, so as to keep the wireless network of the mobile terminal in the best state. However, the carrying capacity of each cell is limited. If there are too many mobile terminals residing in a cell with the best signal quality, then the cell will be congested, thus affecting the mobile terminals residing in the cell....
