Referring to FIG. 4, an embodiment of the present invention will be described in detail below with reference to FIG.

The method for realizing the automatic migration of the AP hotspot terminal device between the CPE and the Ufi to save the wireless network tariff and charging the Ufi device in the process mainly includes the following steps: Step 1. The CPE itself connects to the wired network through the WAN interface. .

Step 2. Other devices can establish a small LAN shared access network through the LAN interface on the CPE or the self-built AP hotspot.

Step 3. Wireless terminal devices with AP functions (for example, Ufi devices) are connected to the WWAN wirelessly.

Step 4: Some wireless terminal devices are connected to the AP hotspot built by the Ufi device. These wireless terminal devices can share access to the wireless network through Ufi devices.

Step 5: The Ufi device is connected to the CPE through the USB interface. After detecting the CPE, the CPE will send an interactive command (which can be an at command or other custom protocol) to the Ufi device. After receiving the Ufi device, the Ufi device will receive its own hotspot. The information such as the SSID and the password is sent to the CPE. After receiving the CPE, the AP hotspot is turned off, the wireless network is disconnected, and the connection confirmation command sent by the CPE is awaited, and the charging half-sleep state is entered. Step 6. After the CPE obtains the SSID and password of the hotspot of the Ufi device, create a hotspot with the same name and password, and broadcast it.

Step 7. The wireless terminal device connected to the Ufi device will automatically re-access the network to the CPE. The CPE will send a connection confirmation message to the Ufi class through the fixed broadband Internet sharing network of the CPE. The device informs its connection status.

Step 8. When the CPE detects that the Ufi device is removed, the newly opened UFI class device and the SSID hotspot are closed. If the Ufi device does not receive the connection confirmation message within the waiting time, it considers that it has been from the CPE. Unplug, restart the hotspot that was turned off before the broadcast, broadcast and reconnect to the WWAN. After the wireless terminal device disconnects from the CPE, it searches for the hotspot with the SSID of the Ufi device and reconnects to the Ufi device.

In the embodiment of the present invention, in conjunction with FIG. 2 and FIG. 4, a process for realizing automatic migration of AP hotspot users between the CPE device and the Ufi device to save the wireless network tariff is described in detail.

The CPE and Ufi devices implement automatic migration of AP hotspot users to save wireless network tariffs, including the following steps:

Step S201: The CPE detects whether the Ufi-type device is inserted. If it is inserted, the process proceeds to step S202, and if not, the process ends.

Step S202: After detecting that the Ufi device is inserted, the CPE sends an instruction (which may be an at command or another customized protocol) to notify the Ufi device that the device has been connected, and then proceeds to step S203.

Step S203: The Ufi device receives the instruction sent by the CPE and returns the received instruction.

The CPE determines whether the instruction returned by the Ufi device is received, if yes, proceeds to step S204, and if not, returns to step S202;

Step S204: The CPE sends an instruction to obtain information such as an SSID from the Ufi device.

Determining whether the SSID or the like is obtained, if the CPE does not receive the confirmation message returned by the Ufi device, the process returns to step S204, and if the confirmation message returned by the Ufi device is received, the process proceeds to step S206;

Step S205: Send the SSID and the password of the wireless device that has been accessed on the Ufi device to the CPE by using an instruction.

After receiving the request, the Ufi device will send the SSID and password of the hotspot that it has built. The information is sent to the CPE.

Step S206: The CPE creates a hotspot with the SSID name and password, broadcasts it, and sends a message of the newly created hotspot to the Ufi device, and then proceeds to step S207.

If the CPE does not receive the information returned by the Ufi device, it will return to step S204. If the CPE receives the information returned by the Ufi device, it will create a hotspot with the SSID name and password, broadcast it, and give the Ufi device. The message of the newly created hotspot is sent, and then proceeds to step S207.

Step S207: After receiving the message of the same name hotspot established by the CPE, the Ufi class device closes its own hotspot, disconnects the connected WWAN, and connects to the wireless terminal device on the Ufi hotspot, and searches for the disconnected relationship again. Connected to the hotspot of the same name on the CPE, all the wireless terminal devices originally on the Ufi class have all migrated to the CPE, and access the network resources through the wired network connection connected by the CPE, and then go to step S208.

Step S208: The CPE sends an instruction to confirm the status to the Ufi device at intervals.

The CPE detects whether the Ufi-type device is still connected thereto, and transmits an instruction to maintain the connection state to the Ufi-type device at intervals, and then proceeds to step S209.

Step S209: After detecting the message of keeping the connection sent by the CPE, the Ufi device keeps the hotspot and the wireless network off, enters the shallow sleep state, and performs charging, and then proceeds to step S210.

Step S210: After the CPE detects that the Ufi device has been unplugged, the CPE closes the hotspot that has just been established, and then proceeds to step S211.

Step S211: If the Ufi-type device receives the message of keeping the connection sent by the CPE, the process returns to step S209, and if the message of keeping the connection sent by the CPE is not received within the set time, it is considered to have been removed from the CPE. Then, the Ufi device will restart the hotspot that was just turned off and dial the connection to complete the wireless network connection. The wireless terminal device just connected to the hotspot of the CPE will search for the Ufi hotspot and access it. The process of CPE migration back to Ufi-like devices, and access to network resources through WWAN sharing connected by Ufi-type devices.

The process of automatic migration of AP hotspot users between the entire CPE and Ufi devices to save wireless network tariffs ends.
