[0075] see figure 1 , the first embodiment of the present invention provides a method for identifying a pseudo base station, including:

[0076] Step 101: Receive the broadcast signaling of the base station in the cell during the cell selection phase, and obtain the first risk coefficient according to the broadcast signaling and the pre-stored adjacent cell information of the adjacent cell of the cell where the cell resides, where the broadcast signal The order at least includes: configuration information of the cell on which to reside.

[0077] Wherein, the configuration information includes basic configuration information for the user terminal to access in the cell where it resides, and basic identification information such as public land mobile network identification (PLMN ID) and cell identification (Cell ID).

[0078] The first risk coefficient indicates the degree of risk that the base station residing in the cell is a false base station.

[0101] see figure 2 , the second embodiment of the present invention provides a method for identifying a pseudo base station, including:

[0102] Step 201, during the cell selection phase, receive the broadcast signaling of the base station residing in the cell, and obtain the first risk coefficient according to the broadcast signaling and the pre-stored adjacent cell information of the adjacent cell of the residing cell, where the broadcast signal The order at least includes: configuration information of the cell to reside on;

[0103] Specifically, step 201 includes:

[0104] Obtain the configuration information of the resident cell in the broadcast signaling, and determine whether the pre-stored adjacent cell information of the adjacent cell of the resident cell has the configuration information of the resident cell:

[0105] If it exists, a first risk coefficient whose value is a first preset value is obtained.

Abstract

The present invention provides a method and apparatus for identifying a rogue base station. The method comprises: receiving broadcast signaling of a base station in a camping cell in a cell selection stage, and obtaining a first risk coefficient according to the broadcast signaling and pre-stored neighboring cell information of a neighboring cell of the camping cell; when a position is changed, receiving position update acknowledgment signaling from the base station after a position update process is executed, and obtaining a second risk coefficient according to the position update acknowledgment signaling; in a connection establishment stage, receiving information content from the base station, and obtain a third risk coefficient according to the information content; performing calculation according to the first risk coefficient, the second risk coefficient and the third risk coefficient, so as to obtain a prejudgment result; and when the prejudgment result exceeds an identification threshold, giving a risk prompt that the base station is a rogue base station. The present invention resolves the problem of an existing malicious information prevention policy failing to identify a rogue base station.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and device for identifying a pseudo base station. Background technique [0002] A pseudo base station is a base station that pretends to be an operator. Pseudo base station equipment is generally composed of a host computer and a computer. It collects mobile phone card information centered on it and within a certain radius through SMS group senders, SMS transmitters and other related equipment, and uses other people's mobile phone numbers to forcibly send fraudulent, Short messages such as advertising sales. [0003] The purpose of the pseudo base station is to attract as much as possible a nearby user terminal (such as a mobile phone) to camp on, and to send information to the camped mobile phone as quickly as possible. After completion, the mobile phone may leave the cell of the pseudo base station by itself as it moves, or the mobile phone may be driven away from...
