Description
Technical Field
The invention belongs to the technical field of mobile communication, and particularly relates to an online reduction system and a reduction method for a called subscriber number of a mobile telephone network.
Background
In the fixed telephone network, each telephone is distributed with a telephone number, and because the area where the telephone is located and the switching equipment providing services are relatively fixed, each time a fixed telephone user is called, the fixed telephone number distributed by the telephone is used for calling, and the switching equipment providing services for the fixed telephone user can be found according to the number characteristics, so that the called number used in the fixed telephone calling is the telephone number of the called user, and the called number and the telephone number are the same number; in a mobile telephone network, each mobile phone is also assigned with a telephone number, but because of its mobility characteristics, the area where the mobile phone is located and the switching device providing services may be different at different times, and there is no static correspondence between the telephone number and the switching device providing services, and it is not possible to directly find the switching device providing services according to the characteristics of the subscriber number. Therefore, when a mobile subscriber is called, it is first required to obtain the information of the switching device currently serving the subscriber and apply for a temporary number (also called roaming number) for calling the subscriber, and then initiate a call using the temporary number as the called number and find the switching device serving the temporary number according to the characteristics of the roaming number. The user number and the roaming number are different numbers, and the roaming number is temporarily allocated for each call and has no fixed corresponding relation with the user number.
Currently, mobile users have become the main target group of telecommunication network crimes, and various harassment and fraud incidents are layered endlessly and are one of the main security threats faced by public telecommunication networks. For the network security protection of the mobile phone service, firstly, the number information of the called user is acquired, the call relation is clarified, and then the relevant protection strategy is implemented on the basis of the information, the traditional called number acquired from the call control information is only a roaming number, is not a real called user number, and cannot position the call relation with the calling user, so that the online restoration method of the called user number in the mobile call needs to be researched and designed, and technical support is provided for the security protection of the mobile phone service. In order to realize the telephone connection of the mobile subscriber, the service control information interacted between the devices in the mobile telephone network is divided into two types, one is the call control information similar to the fixed telephone network, the other is the mobile management information specific to the mobile telephone network, the call control information is used for controlling the establishment, the maintenance, the release and the like of the call, and the mobile management information is used for updating the position of the subscriber, asking for the roaming number and the like. As a third party platform, the mobile phone network security protection system needs to perform correlation analysis and processing on the two types of information to restore the roaming number to the subscriber number, so as to restore the called subscriber number.
