In this way to identify the fake base station cell, the mobile terminal must first reside in the fake base station cell, and the intrusion of spam messages in the fake base station cell cannot be avoided
In addition, the fake base station can trigger the location update in a short time without changing the LAC after sending spam messages by adjusting the periodic location update duration. In this case, the existing fake base station identification mechanism cannot detect the identity of the fake base station cell. exist

Embodiment Construction
[0020] The "comprising" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. In addition, the term "coupled" includes any direct and indirect electrical connection means. Therefore, if it is described in the text that a first device is coupled to a second device, it means that the first device may be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connection means. device. The word "connection" here includes any direct and indirect, wired and wireless means of connection. The present invention is illustrated by the description of the following embodiments and accompanying drawings, but the methods and steps in the following ...

The scheme provides at least one pseudo base station cell identification method and device, and the method comprises the steps: when a communication device receives a short message within a first preset time after the communication device resides in a target cell, judging whether the communication device triggers position updating within a second preset time after the communication device receives the short message, and determining whether the network corresponding to the target cell rejects the location update request; and when the communication device triggers location update again within the second predetermined time after receiving the short message and the network corresponding to the target cell rejects the request of location update, determining that the target cell is a pseudo base station cell. The method has the advantages that the occurrence that the mobile terminal resides in the pseudo base station can be effectively prevented and reduced, and the probability that the mobile terminal receives fraud short messages and advertisement promotion is reduced, so that the user experience is improved.
Description
technical field [0001] The present invention relates to the identification of pseudo-base stations, and more specifically relates to a method and device for identifying cells of pseudo-base stations suitable for communication devices. Background technique [0002] With the rapid development of wireless communication technologies such as GSM technology, W-CDMA technology, and LTE technology, single-mode mobile phones and multi-mode mobile phones have been widely used, and lawbreakers often send spam messages (or short messages) to mobile terminal users through pseudo base stations. ), carry out advertising promotion, fraud, etc., seriously affecting user experience. [0003] Generally speaking, the pseudo-base station consists of four parts: host computer, engineering computer, notebook computer and signal jammer. The fake base station obtains the broadcast control channel (Broadcast Control Channel, BCCH) frequency point and field strength information of the 2G neighboring ...
