[0140] Step 1406: Receive an unlock request sent by the user equipment UE;

[0141] Step 1407: After receiving the request, the network side first generates a random number according to the received unlock request; then, generates an unlock password according to the random number, the device identifier of the user equipment, and the encryption algorithm.

[0142] Step 1408: Send a reception message to the user equipment UE, where the unlock message includes the random number, unlock password, unlock ID, and/or network ID to be unlocked.

[0143] Step 1409: After the user equipment UE receives the unlock message, it calculates according to the random number, the device identification of the user equipment UE, and uses the same algorithm as the network side to obtain the password; determine the calculated password and the decryption password Whether they are consistent or not, if they are consistent, unlock according to the information carried in the unlock message. The unlocking process is as described in Embodiment 15, and will not be repeated here.

[0144] In step 1410, after unlocking is successful, an unlocking success message is delivered to the network side.

[0145] It can be seen from the above that when the user unlocks, he can send an unlock request to the network side, receive the unlock message returned by the network side, and unlock according to the unlock message. There is no need to use a tool to unlock every time, which brings convenience to the user. Enhance the competitiveness of communication terminals.
