Problems solved by technology

However, when the communication terminal switches to a legal cell, it will measure the adjacent cell again. If the above-mentioned illegal cell is detected and the signal strength of the illegal cell is higher than the threshold value, the communication terminal will switch to the illegal cell again for registration. , disrupting the user's normal communication
[0005] Therefore, in the process of implementing the present invention, the inventor found that the prior art has at least the following disadvantages: the existing communication terminal cell switching method is often affected by co-channel interference, which interrupts the normal communication of the user and reduces user satisfaction , causing adverse effects on communication terminal manufacturers and operators

Embodiment Construction

[0020] image 3 It is a flow chart of an embodiment of the terminal cell handover method provided by the present invention.

[0021] Such as image 3 As shown, the terminal cell handover method of this embodiment includes:

[0022] S01: measure a cell that is not in the blacklist and whose signal strength is higher than the threshold value, switch to the cell for registration;

[0023] S02: Enter the idle state after successfully registering in the cell.

[0024] The terminal cell handover method in this embodiment measures a cell that is not in the blacklist and whose signal strength is higher than the threshold before switching to the cell, ensuring the signal quality of the cell to be switched to the greatest extent and avoiding Switch to an illegal cell.

[0025] Figure 4 It is a flow chart of an embodiment of the terminal cell handover method provided by the present invention.

[0026] Such as Figure 4 As shown, in an embodiment of the terminal cell switching met...

Abstract

The invention discloses a terminal subdistrict switching method, including steps of switching to the subdistrict to register when measuring that the subdistrict is not in the blacklist and signal intensity is higher than a threshold value; entering free state when the subdistrict registers triumphantly. The invention at the same time discloses corresponding communication terminals. The terminal subdistrict switching method and communication terminal of the invention avoid switching the communication terminal to illegal subdistrict and co-channel interference, which improves reliability.

Description

technical field [0001] The present invention relates to the communication field, in particular to a terminal cell switching method and a communication terminal. Background technique [0002] In the local wireless communication network system, due to limited frequency point resources and network planning and other issues, co-frequency interference often occurs between different networks. Co-channel interference refers to the fact that two or more communication networks have the same frequency point, causing users who should have resided in a network such as network A to reside on another network such as network B, and network B is illegal for users The network cannot provide normal services, so that users cannot initiate normal communication services, such as voice calls, or the services are often interrupted due to frequent switching. The reason why users who should reside in network A reside on network B, which has the same frequency point but is an illegal network, is mai...
