Detailed Description
The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.
Example 1

And step S2, acquiring DHCP supply/confirmation messages of the Wi-Fi hotspots.
And step S3, judging whether the DHCP providing/confirming message meets the preset condition, and if so, identifying the type of the Wi-Fi hotspot as the mobile phone Wi-Fi hotspot.
In specific implementation, after the STA (station) is successfully associated, the STA requests an IP address from a DHCP server.
Then, in step S1, a DHCP discover/Request (discovery/selection message) is sent to the Wi-Fi hotspot, and a Parameter Request List (Parameter Request List) is filled with a Requested Option (43), that is, the Vendor Specific Info Request information.
Next, in step S2, a DHCP offer/acknowledge (offer/ack) message of the Wi-Fi hotspot is received.
As an alternative embodiment, referring to fig. 2, step S3 includes the following steps:
step S301, judging whether the supplier specific information in the DHCP providing/confirming message includes ANDROID _ METERED keyword, if yes, executing step S302; if not, go to step S303.
And S302, identifying the type of the Wi-Fi hotspot as a mobile phone Wi-Fi hotspot, wherein the mobile phone serving as the Wi-Fi hotspot is an android mobile phone.
Step S303, judging whether a Server IP Address (Server IP Address) in a BootP field in the DHCP provision/confirmation message belongs to a target IP Address field, if so, executing step S304; if not, step S305 is executed.
Entering step S303, it means that the Wi-Fi hotspot does not belong to an android phone Wi-Fi hotspot, and then, in step S303, it is determined whether the Wi-Fi hotspot conforms to the characteristics of the apple phone Wi-Fi hotspot. The IP address field of the iphone often belongs to a specific address field: 172.20.10.*. Therefore, whether the Wi-Fi hotspot meets the server IP address characteristic of the apple mobile phone Wi-Fi hotspot can be identified by judging whether the server IP address in the BootP field in the DHCP provision/confirmation message belongs to the target address field.
Step S304, judging that a Server Host Name (Server Host Name) field in a BootP field in the DHCP providing/confirming message is empty, if so, executing step S305; if not, go to step S306.
And S305, identifying the type of the Wi-Fi hotspot as a common Wi-Fi hotspot. That is, the Wi-Fi hotspot does not belong to the mobile phone Wi-Fi hotspot.
And S306, identifying the type of the Wi-Fi hotspot as a mobile phone Wi-Fi hotspot, wherein the mobile phone serving as the Wi-Fi hotspot is an apple mobile phone.
Based on the method for identifying the Wi-Fi hotspot type, the identification of the mobile phone hotspot can be realized without adding the information (such as MAC address and IP address) of the mobile phone hotspot into a local terminal database, and the coverage rate of identifying the Wi-Fi hotspot is improved.
Example 2

The method for identifying a Wi-Fi hotspot type of the present embodiment is substantially the same as the method for identifying a Wi-Fi hotspot type of embodiment 1, and referring to fig. 3, the method for identifying a Wi-Fi hotspot type further includes the following steps:
and step S4, closing the preset flow request.
In step S4, the STA may close the automatic playing in the Wi-Fi mode, stop the automatic upgrading of the software, and issue a traffic prompt to achieve the purpose of reducing the consumption of the paid traffic; meanwhile, the use of a mobile phone hot spot RF (radio frequency) can be reduced, and the power consumption of a mobile phone Wi-Fi hot spot is reduced.
Example 3

In specific implementation, after the association of the STA is successful, the STA requests an IP address from a DHCP server.
Then, the message sending unit 501 sends DHCP discover/Request to the Wi-Fi hotspot, and fills a Requested Option (43), that is, the Vendor Specific Info Request information, in the Parameter Request List.
Next, the message obtaining unit 502 receives a DHCP offer/acknowledge message of the Wi-Fi hotspot.
As an alternative implementation, referring to fig. 2, the type identification unit 503 identifies the type of the Wi-Fi hotspot according to the following steps:
step S301, judging whether the supplier specific information in the DHCP providing/confirming message includes ANDROID _ METERED keyword, if yes, executing step S302; if not, go to step S303.
And S302, identifying the type of the Wi-Fi hotspot as a mobile phone Wi-Fi hotspot, wherein the mobile phone serving as the Wi-Fi hotspot is an android mobile phone.
Step S303, judging whether a Server IP Address (Server IP Address) in a BootP field in the DHCP provision/confirmation message belongs to a target IP Address field, if so, executing step S304; if not, step S305 is executed.
Entering step S303, it means that the Wi-Fi hotspot does not belong to an android phone Wi-Fi hotspot, and then, in step S303, it is determined whether the Wi-Fi hotspot conforms to the characteristics of the apple phone Wi-Fi hotspot. The IP address field of the iphone often belongs to a specific address field: 172.20.10.*. Therefore, whether the Wi-Fi hotspot meets the server IP address characteristic of the apple mobile phone Wi-Fi hotspot can be identified by judging whether the server IP address in the BootP field in the DHCP provision/confirmation message belongs to the target address field.
Step S304, judging that a Server Host Name (Server Host Name) field in a BootP field in the DHCP providing/confirming message is empty, if so, executing step S305; if not, go to step S306.
And S305, identifying the type of the Wi-Fi hotspot as a common Wi-Fi hotspot. That is, the Wi-Fi hotspot does not belong to the mobile phone Wi-Fi hotspot.
And S306, identifying the type of the Wi-Fi hotspot as a mobile phone Wi-Fi hotspot, wherein the mobile phone serving as the Wi-Fi hotspot is an apple mobile phone.
Based on the system for identifying the Wi-Fi hotspot type, the identification of the mobile phone hotspot can be realized without adding the information (such as MAC address and IP address) of the mobile phone hotspot into a local terminal database, and the coverage rate of identifying the Wi-Fi hotspot is improved.
Example 4

The system for identifying a Wi-Fi hotspot type of the present embodiment is substantially the same as the system for identifying a Wi-Fi hotspot type of embodiment 3, and referring to fig. 5, the system for identifying a Wi-Fi hotspot type further includes a flow control unit 504; after the type identification unit 503 identifies that the type of the Wi-Fi hotspot is a mobile phone Wi-Fi hotspot, the flow control unit 504 closes the preset flow request.
In specific implementation, the flow control unit 504 closes the automatic playing of the STA in the Wi-Fi mode, stops the automatic upgrading of software, and sends a flow prompt, so as to achieve the purpose of reducing the consumption of paid flow; meanwhile, the use of the mobile phone hot spot RF can be reduced, and the power consumption of the mobile phone Wi-Fi hot spot is reduced.
