s170, if the calling number does not have the international long distance dialing authority, the behavior that the user dials a plurality of called numbers by using the calling number is an illegal calling behavior.
According to the embodiment of the invention, whether the user is an illegal call can be identified, and the phenomenon that lawless persons try to find the network data loophole through the dialing in a sleeving way so as to initiate the illegal international long distance call to cause the loss of the telephone charge is avoided.
Fig. 2 shows a configuration diagram of a network according to an embodiment of the present invention. As shown in fig. 2, the present invention analyzes the call of the IMS user through the illegal dialing identification module, extracts the called number condition of the call by analyzing the call signaling, and determines whether the call belongs to the dialing set through a certain rule.
The System for preventing the IMS service from being stolen consists of access equipment, a call analysis System, a service Operation Support System (BOSS) and network equipment.
1) And the access equipment comprises a PBX, an IAD and an ONU and mainly realizes the IP access side function of the IMS user.
2) The network device, the network side device includes an HSS, an Interworking Session Border Controller (ISBC), an MGCF, an Inquiry Call Session Control Function (ICSCF), and other devices, and a specific networking mode and a specific implementation manner of functions of each module are not limited.
3) The call analysis system collects IMS user registration and call signaling mainly through an illegal dialing identification module, extracts a called number dialed by a user for analysis, outputs the user who has dialing and does not have international long-distance authority by inquiring the international long-distance authority of an IMS user at a BOSS side, pushes the user to a client manager corresponding to the user through a short message or a work order, verifies the user by the client manager and the user, and takes corresponding measures to avoid call charge loss.
Fig. 3 is a flow chart illustrating an illegal call identification method according to another embodiment of the present invention. As shown in fig. 3, the method for identifying an illegal call according to the embodiment of the present invention includes the following steps:
in a first step 101, an IMS user on an access device (PBX/IAD/ONU) initiates a registration or call, and a call analysis module collects user signaling.
In the second step 102, 103, the illegal dial-in identification module outputs a number set meeting the preset condition of the illegal dial-in condition according to the preset condition. The preset conditions are as follows: the length of the called number is more than 11 bits, the length of the same digit of the called number is 8 bits, the number of times of calling the number containing the common digits is more than 100 times every day (any condition can be adjusted according to the condition), the international long distance authority of the user of the BOSS system is inquired, and if the international long distance authority is not possessed, the number is considered as illegal set dialing.
And step 104-. And the illegal set dialing can be prevented by configuring a corresponding interception strategy on the access equipment.
Fig. 4 is a diagram illustrating a partial call behavior of an identified illegal call number according to an embodiment of the present invention. As shown in fig. 4, by the illegal dial-in identification module, the IMS private line number meeting the conditions of 2018, 9, 10 and the dial condition are extracted, as shown in the figure, it can be seen that the IMS private line with the IP address of 120.209.0.182 uses the calling number of 05582701801, and the dial number format is, for example, uncertain number + specific number, and the calling number obviously belongs to the illegal dial-in attempt.
In the embodiment of the invention, the calling number can be pushed to a customer manager, the customer manager confirms whether the illegal dial-in is caused by the invasion of the IMS special line access equipment, and after confirmation, safety reinforcement can be carried out, and the illegal dial-in is successfully avoided.
In the embodiment, the system can successfully identify and plug in the stage of the illegal user in the set dialing attempt, so that the loss of telephone charge is avoided, and the system has very important practical value.
According to the embodiment of the invention, an illegal over dialing identification module is constructed, user signaling is collected and analyzed, illegal over dialing is accurately identified, and a number where over dialing occurs is found out in time, so that a lawless person can be prevented from finding a network data leak through over dialing attempt, and further, illegal international long distance calling is initiated to cause call charge loss.
