Problems solved by technology

In method one, a list of information to be intercepted needs to be established in advance, but the fake base station can use the legal phone number of the live network to send text messages to users, and the fake base station is not connected to the live network. to intercept
In method 2, after the interception device judges the spam SMS, it needs to notify the live network HLR to stop the calling user from sending SMS again, but the fake base station is not connected to the live network, and the second method cannot intercept the spam SMS sent by the fake base station

Embodiment 1

[0027] Aiming at the problems existing in the prior art, Embodiment 1 of the present invention provides a method for intercepting spam messages of pseudo base stations, by analyzing the working principle of spam messages issued by pseudo base stations, and intercepting spam messages of pseudo base stations in a targeted manner, thereby By intercepting spam messages sent by pseudo base stations, the user experience is improved. Among them, the working principle of the fake base station sending spam messages is: the fake base station obtains the frequency point information and system broadcast messages of the operator network, and then adjusts the frequency point information and system broadcast messages of the fake base station to the frequency point information of the operator network It is the same as the system broadcast message, so as to attract terminal equipment to connect to the pseudo base station, and induce the terminal equipment to initiate the location area update pr...

Embodiment 2

[0059] Based on the same inventive concept as in Embodiment 1, Embodiment 2 of the present invention provides a method for intercepting spam messages from fake base stations, by analyzing the working principle of sending spam messages from fake base stations, and intercepting spam messages from fake base stations in a targeted manner. In this way, the spam messages sent by the fake base station are intercepted, thereby improving user experience. Such as figure 2 As shown, the pseudo base station spam interception method comprises the following steps:

[0060] Step 201, judging whether the terminal device has received a terminal identification request fed back by the network; if yes, execute step 202; if not, execute step 208.

[0061] Step 202, judging whether the terminal device has received an authentication request message fed back by the network; if yes, execute step 203; if not, execute step 207.

[0062] Step 203, read the authentication random number from the authent...

Embodiment 3

[0070] Based on the same inventive concept as in Embodiment 1, Embodiment 3 of the present invention provides a method for intercepting spam messages from fake base stations. By analyzing the working principle of sending spam messages from fake base stations, and intercepting spam messages from fake base stations in a targeted manner, In this way, the spam messages sent by the fake base station are intercepted, thereby improving user experience. Such as image 3 As shown, the pseudo base station spam interception method comprises the following steps:

[0071] Step 301, obtaining and storing LAC ID information and cell ID information.

[0072] Step 302, when the terminal device reselects from the first cell to the second cell, use the LAC ID and cell ID of the second cell, and / or the LAC ID and cell ID information to determine whether the network is a fake base station or a legitimate base station. When it is determined that the network is a pseudo base station, the terminal ...

Abstract

The invention discloses a method and equipment for intercepting junk short messages of fake base stations. The method includes: obtaining LAC ID and cell ID; if the mapping relationship is not satisfied, determining that the network is a fake base station; otherwise, reporting a location area update request message to the network, Start a specific timer; if it does not time out, and the authentication request message fed back by the network is received, read the authentication random number from the authentication request message, and determine whether the fixed bit is the set value; if so, determine that the SMS is legal Normal text messages from the base station; otherwise, it is determined that the text message is a spam text message from a fake base station; in addition, it is judged whether the location area update rejection message fed back by the network is received; if it is or the specific timer expires, it is judged whether the network signal strength is greater than the preset threshold value; if If yes, it is determined that the short message is a normal short message of a legitimate base station; otherwise, it is determined that the short message is a spam short message of a fake base station. In the embodiment of the present invention, the user's experience is improved by intercepting spam short messages of pseudo base stations in a targeted manner.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and equipment for intercepting spam short messages of pseudo base stations. Background technique [0002] At present, there are many fake base stations in the existing network. The fake base stations can absorb the terminal equipment into the service range of the fake base station, and know the IMSI (International Mobile Subscriber Identification Number, International Mobile Subscriber Identification Number) of the terminal equipment, and then send spam messages to the terminal equipment. , has a great impact on user experience. Among them, the spam text messages of pseudo base stations include promotional text messages, fraudulent text messages, and the like. Therefore, it is of great significance how to intercept spam text messages of pseudo base stations, thereby improving user experience. [0003] In the prior art, methods for intercepting spam text messages include: Meth...
