Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
The first embodiment is as follows:
the present embodiment provides a pseudo base station identification method, please refer to fig. 1, which specifically includes:
step S101, receiving information sent by N base stations, wherein N is a natural number greater than or equal to 4;
step S102, calculating self position information according to the information sent by every 3 base stations in the N base stations;
step S103, identifying the pseudo base station according to the calculated self position information.
Specifically, in order to avoid the influence of the pseudo base station on the user terminal, if the pseudo base station can be conveniently identified, the terminal can be prevented from being interfered by the pseudo base station, and the security and the user experience of the terminal are improved. When the pseudo base station is established, the information of the normal base station is usually disguised, but the information cannot disguise the position information of the normal base station, and the position information of each base station is fixed, so that the position information of a plurality of terminals can be obtained through the measurement of the position information of the base station and the terminals, and the pseudo base station can be identified according to the obtained position information of the plurality of terminals and the actual position information of the terminals.
Specifically, for step S101, receiving information sent by N base stations, where N is a natural number greater than or equal to 4, specifically, in a using process of the terminal, the base station may broadcast and send information to the terminal, where the base station includes a normal base station and a pseudo base station, and the information sent by the pseudo base station is specifically information of a base station disguised by the pseudo base station; then, the terminal receives the information transmitted by the base station. In addition, in order to enable the terminal to identify the pseudo base station, it is necessary to ensure that the terminal receives information transmitted by at least 4 base stations. The terminal then analyzes the received information transmitted by the base station and calculates its own location information based on the received information transmitted by the base station.
In step S102, the terminal calculates the self-location information according to the received information sent by the base station, and specifically, the terminal may measure the location information by using an Enhanced Observed Time Difference (E-OTD) technique to obtain the self-location information of the terminal. Specifically, the method for calculating the self-position information by the terminal includes that the terminal receives information sent by N base stations, and then selects information sent by any 3 base stations from the N base stations to calculate the self-position information, and includes: the terminal receives the information sent by each base station, acquires the position information XnYn of the base station, OTD (Observed Time Difference) parameters, and acquires the radio wave transmission speed Sn, and then acquires the aforementioned information of any 3 base stations, and can determine the position information of the terminal itself by triangulation. Further, the terminal receives signals sent by each base station to obtain TOA (Time Of Arrival) parameters; in addition, the LMU (Location Measurement Unit) may obtain an RTD (Round trip delay) parameter; then, the terminal transmits the TOA and RTD parameters to a GSM (Global System for mobile communications) network to determine OTD parameters. After the OTD parameters are determined, the location information of the terminal may be calculated in the local of the terminal or in the network, that is, the location calculation may be implemented by a location calculation function module in the local of the terminal or in the network. It should be understood that, in order to determine the location of the terminal, the OTD measurement and the RTD measurement are both calculated by using information transmitted from three base stations. As is apparent from the principle of permutation and combination, the number of terminal location information items obtained by calculating the location information items is specifically P ═ N × (N-1) × (N-2)/6. If the terminal receives the information sent by the four base stations, the number of the obtained self position information is 4; if the terminal receives the information transmitted by seven base stations, the number of the obtained self-position information is 30.
Further, for step S103, identifying the pseudo base station according to the calculated self-location information includes: judging whether the calculated position information of the respective body is the same or not; if the base stations are different, screening out pseudo base stations from the N base stations; or judging whether the difference value between the position information of each self exceeds a preset value; and if the difference value exceeding the preset value exists, screening out the pseudo base stations from the N base stations. Specifically, the obtained own position information Pn of P terminals is compared to check whether an abnormal position exists, that is, if the values of the own position information Pn of P terminals are the same or the difference between the own position information Pn of P terminals does not exceed a preset value, it indicates that no pseudo base station exists, and subsequent normal operation can be performed; if the P self-position information Pn have different values or a difference value exceeding a preset value exists in the difference values between the P self-position information Pn, it is determined that a pseudo base station exists. The difference between the Pn can be optionally calculated by two or more Pn, or the difference between the Pn can be calculated by selecting the appointed Pn; it may be specifically selected according to the needs, and this embodiment does not limit it. After the existence of the pseudo base station is identified, the pseudo base station is identified from the N base stations, and the identification method may specifically be to determine current location information of the terminal, and then screen out self location information different from the current location information of the terminal, that is, the pseudo base station exists in the base station corresponding to the self location information different from the current location information of the terminal. Then, comparing and checking the own position information which is different from the current position information of the terminal, so as to determine the pseudo base station, wherein if the same base station can be identified, the same base station is the pseudo base station. Further, after the terminal own position information is obtained, the terminal own position information may be compared with the terminal current position information, and if the terminal own position information is different from the terminal current position information, it is indicated that a pseudo base station exists in the base station corresponding to the terminal own position information. The current position information of the terminal is the current actual position information of the terminal, and can be obtained through a satellite.
Specifically, in the pseudo base station identification method provided in this embodiment, it is known according to the satellite positioning principle, and if the position of the 3 th point is known, the position of the 4 th point can be derived; the base stations communicating with the terminal can be arranged and combined, 3 base stations are selected for calculation to obtain the position information of the terminal, if the calculated position information of the terminal is not matched with the known actual position information of the terminal, the fact that a pseudo base station exists in the 3 base stations corresponding to the position information of the terminal is indicated, the pseudo base station can be selected by calculating a data comparison result through a plurality of groups of base stations and using an exclusion method. In addition, the actual position information of the terminal may be acquired by a satellite.

Namely, the pseudo base station can be identified through the self position information calculated according to the information sent by the base station, so that the identification of the pseudo base station is conveniently realized; furthermore, after the pseudo base station is identified, the interference of the pseudo base station can be avoided, or the identified pseudo base station is reported to a monitoring mechanism to manage the pseudo base station, so that the communication safety and the user experience are improved.

Specifically, the method for performing cell reselection without selecting the pseudo base station may be to add the identified pseudo base station to a blacklist, so that the terminal partially selects the pseudo base station during cell reselection. In addition, the selection of the normal base station for communication may specifically be a selection of a base station with high signal strength for communication at a time.
By the communication method in the embodiment, after the pseudo base station is identified, the terminal selects the non-pseudo base station for communication, so that normal communication of the terminal is ensured, the terminal is prevented from being affected by the pseudo base station, and the safety of the terminal and the user experience are improved.

Specifically, after the position information of the pseudo base station is obtained, the position information of the pseudo base station may be reported to a target platform, and the target platform manages the pseudo base station according to the reported position information of the pseudo base station. The target platform can be a false base station reporting platform of a public security organization.
