Embodiment Construction

[0028] The basic idea of ​​the present invention is to integrate part of the functions of the wireless network controller and the core network in the traditional base station to form a special base station that can obtain the IMSI of the mobile communication terminal. The base station can simulate the current wireless network function but does not provide communication services. After completing the location update process, the base stations mentioned below all refer to this special base station. When the mobile communication terminal detects a strong signal in the coverage area of ​​the base station and there is no communication service, the mobile communication terminal actively initiates a location update request, and the base station simulates the current wireless network to receive the location update request, and during the location update process of the mobile communication terminal Obtain the IMSI of the current mobile communication terminal.

Abstract

The invention discloses a method for acquiring international mobile subscriber identity (IMSI) of a mobile communication terminal by a base station. The base station is integrated with partial functions of a wireless network controller and a core network; and the method also comprises that: when not having communication service, the mobile communication terminal actively initiates a position update request to the base station; and the base station simulates the current wireless network to receive the position update request, and acquires the IMSI of the current mobile communication terminal in the position updating process of the mobile communication terminal. The invention also discloses a device for acquiring the IMSI of the mobile communication terminal by the base station. The method and the device can timely acquire the IMSI of the mobile communication terminal in the coverage area of the base station.

Description

technical field [0001] The invention relates to a technology for a base station to acquire information of a mobile communication terminal, in particular to a method and a device for a base station to acquire the International Mobile Subscriber Identity (IMSI) of a mobile communication terminal. Background technique [0002] With the rapid development of mobile communication, people use mobile communication terminals more widely, and at the same time, people's dependence on mobile communication terminals is further enhanced; it is this growing demand of people that further promotes mobile communication. development of. [0003] In practical applications, sometimes it is desired to obtain a list of mobile communication terminal users passing through the area for some specific areas, so that when a certain user information needs to be searched, the list can be used to find the location of the user. For example: when the public security department needs to check the flow of peo...
