Because the GOIP equipment is usually installed in a house and accessed to the network through the family broadband when an illegal user implements illegal behaviors through the GOIP equipment, the illegal user can remotely control the GOIP equipment to dial out or send short messages.
Referring to fig. 3, fig. 3 is a flowchart of a third illegal user identification method according to an embodiment of the present invention, as shown in fig. 3, the method includes the following steps:
301, obtaining an internet traffic log of a home broadband user within a preset time duration; the network flow log comprises a family broadband user identifier, a communication protocol and a data length; wherein the home broadband user identification can be represented by a home broadband user account.
In this embodiment, the preset time period may be the latest preset time period, for example, the latest 1 month.
In this embodiment, after determining that the home broadband user is an illegal user, step 304 may be further performed to obtain registration information corresponding to the home broadband user account from the home broadband network service system, so as to assist law enforcement departments in finding the illegal user more conveniently.
As can be seen from the method shown in fig. 3, in the embodiment of the present invention, the internet traffic log of the home broadband user within the preset duration is obtained, and the traffic proportion of the home broadband user belonging to the voice call is counted according to the internet traffic log of the home broadband user, so that the traffic proportion of the voice call in the internet traffic exceeds a certain threshold, the home broadband user with an obvious abnormality is determined as an illegal user, and the registration information registered by the illegal user in the home broadband network service system is further obtained, thereby assisting law enforcement departments to find the illegal user more conveniently.
