All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

FIG. 1 is a schematic flowchart of an identification method according to Embodiment 1 of the present invention. As shown in FIG. 1 , the identification method in this embodiment may include the following steps: Step 101: Obtain user information agent (User-Agent) field information.

Specifically, in this step, the gateway device may receive the HTTP access request packet from the same wireless routing access device, parse the HTTP access request packet, and obtain the User-Agent field information. Specifically, the deep packet inspection (DPI) is performed on the HTTP access request packet, and the User-Agent field information included in the HTTP access request packet is obtained. The User-Agent field information may include information identifying the type of the terminal (product tokens) and the information identifying the terminal operating system.

Optionally, the step may further include receiving, by the report server or the Policy and Charging Rules Function (the PCR and the PCRF), User-Agent field information from the gateway device, where the User-Agent field information is After the gateway device receives the HTTP access request packet from the same wireless routing access device, parses the HTTP access request packet, and obtains the User-Agent field information, and then sends the message to the report server or the PCRF. Sent.

Step 102: According to the User-Agent field information, it is identified whether there are multiple types of platform sharing the same wireless routing access device to access the Internet.

Those skilled in the art can understand that: Each different User-Agent field information can be considered as a platform type. Because the User-Agent field information is generally given by the browser according to the operating system type, the terminal type, the software version of the terminal, and the compatibility, etc., even if a terminal uses different browser software, There will be multiple User-Agent field information, so it will be considered as a different platform type.

In this embodiment, by acquiring the User-Agent field information, it is possible to accurately identify whether there are multiple platform types sharing the same wireless routing access device to access the Internet according to the obtained User-Agent field information, thereby enabling the gateway device to Multiple platform types share the same wireless routing access device to access the Internet corresponding control policy for the above wireless routing access device Access to the Internet for control and billing ensures the accuracy of control and billing.

2 is a schematic flowchart of an identification method according to Embodiment 2 of the present invention. As shown in FIG. 2, the identification method in this embodiment may include the following steps:

Step 201: The gateway device receives an HTTP access request message from the same wireless routing access device.
