Referring to FIG. 2, FIG. 2 is a schematic flowchart diagram of a mobile communication network control method for a mobile terminal according to an embodiment of the present invention. As shown in FIG. 2, the method can include the following steps.

S201. Detect a first cell selection parameter value of a wireless cell currently accessed by the mobile terminal.

In a mobile communication network, the coverage provided by the base station is limited, such as 500m, 1000m, and the like. The communication between the base station and the mobile terminal is carried out by modulating the information onto a spectrum of a certain bandwidth. The area covered by a specific spectrum on the base station is a wireless cell. Controlling the capacity and traffic of the wireless cell can be achieved by adjusting the transmit power of the base station or other parameters that control the use of the radio resource. The mobile terminal can only access one wireless cell at a time and communicate using the spectrum resources of the wireless cell. In order to enable mobile terminals to implement mobile communication in any mobile, wireless The area must be continuously covered, and multiple wireless cells must overlap at the edge of the wireless cell.

Generally, after the mobile terminal is powered on, the mobile terminal establishes contact with the mobile communication network, selects a suitable wireless cell, extracts parameters of the control channel and other system messages, and completes the selection process of the wireless cell. When the value of the first cell selection parameter of the wireless cell is less than 0, it indicates that the wireless path loss of the wireless cell is too large, and the wireless cell usually blocks the mobile terminal from accessing, so that the mobile terminal is disconnected from the network, and the user cannot use the wireless.

Access to the network.

When the mobile terminal determines that the first path loss value exceeds the preset path loss threshold, the mobile terminal may further determine whether the mobile communication network corresponding to the wireless cell exists in the preset mobile communication network list, and if yes, indicates that the user needs to use the mobile communication. The network, in order to prevent the mobile terminal from being off-network, the mobile terminal can control the mobile terminal to remain connected with the wireless cell. In this way, the user can continue to use the mobile communication service provided by the current wireless cell without being affected by the wireless path loss of the current wireless cell.

When the signal of the wireless cell is relatively weak, in order not to affect the user experience, the mobile terminal may perform radio cell reselection, that is, the mobile terminal may select an adjacent wireless cell to access. However, if the neighboring wireless cell can access, the mobile terminal needs to perform steps S308-S310 to determine whether the condition of cell reselection is met.

Generally, the mechanism for optimizing the radio cell reselection is that, in the idle mode, the mobile terminal stays in the accessed radio cell, and detects and measures the signal level of the neighboring radio cell by receiving the system message of the radio cell, and From which various system messages and control information of each neighboring wireless cell are extracted, when a certain condition is met, the mobile terminal will transfer from the previous wireless cell to another wireless cell, that is, the wireless cell reselection.
