step 301: the terminal sends an RRC connection request message to the network side of the roaming operator.

The terminal sends an RRC connection request message to a roaming operator network side; for example, in practical applications, the status may be set as RSU entity.

Step 302: and when the roaming operator network side supports the RSU function, the network side sends an RRC establishment message to the terminal.

After receiving the RRC connection request message sent by the terminal, the roaming operator network side returns an RRC establishment message to the terminal if the roaming operator network side supports the RSU function.

Step 303: the terminal sends RSU connection request information to the network side of the roaming operator.

After receiving an RRC establishment message sent by a Network operator Network side at a roaming location, a terminal sends an RSU connection request message to the Network operator Network side at the roaming location through a Network Attached Storage (NAS) layer, where the connection type is an RSU emergency connection, that is, an attach type (RSU emergency attach).

Step 304: and the roaming operator network side sends an RSU connection confirmation message to the terminal, establishes an RSU emergency bearer and sends an RSU bearer establishment completion message to the terminal.

After receiving the RSU connection request message sent by the terminal, the roaming operator network side sends an RSU connection confirmation message to the terminal and establishes an RSU emergency bearer, where an Access Point Name (APN) of the bearer is an RSU emergency bearer type, and after establishing the RSU emergency bearer, sends an RSU bearer establishment completion message to the terminal.

After receiving an unlocking request message sent by a network control unit of a terminal, a wireless network locking management device at a network side of a roaming operator sends the unlocking request message to an unlocking server at the network side of the original operator.

Step 318: and the original operator network side judges whether the unlocking request message meets a second preset condition.

After receiving the unlocking request message, the unlocking server on the original operator network side determines whether the unlocking request message satisfies a second preset condition, and if the unlocking request message does not satisfy the second preset condition, step 319 is executed; if the unlocking request message satisfies the second predetermined condition, step 320 is executed.

Specifically, after receiving the unlocking request message, the unlocking server on the original operator network side determines that the unlocking request message does not pass if it is determined that the terminal identification information in the unlocking request message cannot be identified, or it is determined that the key in the unlocking request message is not matched, or it is determined that the unlocking type in the unlocking request message is not matched, or it is determined that the unlocking time length in the unlocking request message is not within the preset time length range, that is, the unlocking request message does not satisfy the second preset condition, and then step 319 is executed; if it is determined that the terminal identification information in the unlocking request message can be identified, the key is matched with the key in the unlocking server, the unlocking type is matched with the unlocking type in the unlocking server, and the unlocking time length is within the preset time length range, that is, it is determined that the unlocking request message satisfies the second preset condition, the unlocking request message is determined to pass, and step 320 is executed.

Step 319: the original operator network side does not send new unlocking parameters to the roaming operator network side.

And the unlocking server at the original operator network side judges that the unlocking request message does not meet the second preset condition, namely when the unlocking request message is determined to be failed, new unlocking parameters cannot be sent to the operator network side at the roaming place, the unlocking request fails, and the process is ended.

Step 320: and the original operator network side sends new unlocking parameters to the roaming operator network side.

And the unlocking server at the network side of the original operator judges that the unlocking request message meets a second preset condition, namely when the unlocking request message is determined to pass, new unlocking parameters are sent to the wireless network locking management device at the network side of the roaming operator.

Step 321: and the roaming operator network side sends new unlocking parameters to the terminal.

And after receiving the new unlocking parameter sent by the unlocking server of the original operator network side, the wireless network locking management device of the roaming operator network side sends the new unlocking parameter to the terminal so that the user can unlock the terminal conveniently.

Step 322: and the terminal unlocks the locked network according to the new unlocking parameters.

And after receiving the new unlocking parameters sent by the wireless network locking management device at the network side of the roaming operator, the terminal unlocks the network locking according to the new unlocking parameters.

For example, as shown in fig. 4, the unlocking interface of the terminal receives a new unlocking parameter issued by the unlocking server by using the wireless network locking management device on the network side of the roaming operator, responds to the unlocking, and prompts the unlocking parameter to the user.

In order to more clearly embody the object of the present invention, further illustration is made on the basis of the above-mentioned method embodiment.

The user signs a contract with the operator A, at this time, the terminal equipment of the user can only be used under the network of the operator A, and when the terminal is inserted into a Subscriber Identity Module (SIM) card of other operators, a network locking condition occurs; when the user temporarily goes abroad and does not have the network of the operator A, the user acquires the SIM card of the operator B on business, but the SIM card of the operator B can be locked immediately after being inserted because the terminal of the user is a contract machine; at this time, the user initiates an unlocking registration request, the network control unit of the terminal interacts with the wireless network locking management device of the operator network B, and the network locking information of the terminal is transmitted to the unlocking server of the operator network A through the wireless network locking management device; the terminal sends a request for registering an unlocking server of the A operator network through the unlocking management unit, and after the unlocking server of the A operator network passes, the terminal sends the unlocking request again, wherein the time of the request is exactly the time period of the user going on business in the country, for example, from 12/17/2015 to 3/2016/13/2016; at this time, after the unlocking server of the operator network A receives the request, the request is considered reasonable, and then the unlocking parameter is issued, so that the terminal of the user can be normally used under the network of the operator B without network locking, and the unlocking is overdue after the return country returns to the network of the operator A; therefore, the trouble that a user changes a mobile phone or finds a Wifi network is avoided.

The method for unlocking and locking the network, provided by the embodiment of the invention, comprises the steps of sending an RRC connection request message to a network side of a roaming operator through a terminal; when the roaming operator network side supports the RSU function, the network side sends RRC establishment information to the terminal; the terminal sends RSU connection request information to a roaming operator network side; the roaming operator network side sends RSU connection confirmation information to the terminal, establishes RSU emergency load, and sends RSU load establishment completion information to the terminal; the terminal sends RSU connection completion information and RRC establishment completion information to a roaming operator network side; after detecting the operation of unlocking and registering the request, the terminal sends RSU request information to the network side of the operator at the roaming place; the network side of the roaming operator judges whether the network side supports the RSU function, and if the network side supports the RSU function, the network side sends an RSU confirmation message to the terminal; the terminal sends an unlocking registration request message to a roaming operator network side; a roaming operator network side sends an unlocking registration request message to an original operator network side; the original operator network side judges whether the unlocking registration request message meets a first preset condition, and if so, the original operator network side sends an unlocking registration passing message to the roaming operator network side; the roaming operator network side sends an unlocking registration passing message to the terminal; the terminal sends an unlocking request message to a roaming operator network side after detecting the unlocking request operation; a roaming operator network side sends an unlocking request message to an original operator network side; the original operator network side judges whether the unlocking request message meets a second preset condition, and if so, new unlocking parameters are sent to the roaming operator network side; the roaming operator network side sends a new unlocking parameter to the terminal; the terminal unlocks the locked network according to the new unlocking parameters; when the user is in a foreign place and arrives at a place covered by a non-operator network, and the terminal of the user cannot be connected to the WiFi network, the purpose of unlocking the network locking of the terminal can be achieved, and convenience is provided for the user.
