For some regions, operators want the terminal device to be able to access the internet only in a certain specific cell, which causes a problem: in a place covered by multiple cells, one cell can surf the internet, and one cell cannot surf the internet, but the terminal equipment cannot identify which cell can surf the internet, and only registers networking in the cell with the best signal, so that the cell which cannot surf the internet is possibly registered, and the terminal equipment cannot be used.
The currently mainstream cell locking scheme is a number locking scheme. The principle is as follows: after the terminal equipment is started, inquiring whether a current registered cell is in a locked cell list or not, if so, normally registering networking, and enabling a user to normally use the network; if the current cell is not in the locked cell list, firstly, judging whether the locked cell list is full, namely whether the number of the locked cells reaches a threshold value, if not, adding the current cell into the locked cell list, otherwise, the current cell does not allow a user to surf the internet. There are several disadvantages with this solution:
1. when the number of the locked cells is not full, the user can still use the terminal equipment by taking the terminal equipment to other places, which does not meet the functional requirements of the locked cells;
2. the threshold value of the number of the locked cells is difficult to set, the network environments of all terminal devices are different, the number of the cells which can be searched is different, and the simple threshold value cannot be suitable for various environments;
3. when the searched cell is in roaming state, the roaming cell will also be added into the locked cell list, which is not in accordance with the expected effect of the operator, and the actual cell locking function is not reached.
