Fig. 1 is a flow chart illustrating a method for identifying a pseudo base station according to some embodiments of the present disclosure.
In step S102, the terminal randomly generates a feature number after triggering location update, attaches the feature number to a location update request signaling, and sends the location update request signaling to the currently camped base station. That is, the terminal sends a location update request signaling to the currently camped base station, where the location update request signaling carries the feature number generated by the terminal.
In some embodiments, the base station forwards the location update request signaling to the network side device. The network side equipment forms a return value according to the characteristic number in the location updating request signaling, attaches the return value to the location updating response signaling, and returns the location updating response signaling to the terminal through the base station. For example, the network side device sends a location update response signaling to the base station, where the location update response signaling carries the return value, and the base station forwards the location update response signaling to the terminal after receiving the location update response signaling.
In step S104, the terminal receives the location update response signaling returned from the network-side device.
In step S106, the terminal determines whether the return value in the location update response signaling is a characteristic number formed according to a rule agreed in advance. If so, the process proceeds to step S108, otherwise, the process proceeds to step S110.
In step S108, it is determined that the base station is a legal base station and the network side device is a legal device.
In step S110, it is determined that the base station is a pseudo base station and the network side device is an illegal device.
In the method for identifying a pseudo base station in the foregoing embodiment, the terminal randomly generates a feature number after triggering location update, attaches the feature number to a location update request signaling, and sends the location update request signaling to the network side device through a base station where the terminal currently resides; and receiving a location updating response signaling returned from the network side equipment, judging whether a return value in the location updating response signaling is a characteristic number formed according to a predetermined rule, if so, determining that the base station is a legal base station and the network side equipment is legal equipment, otherwise, determining that the base station is a pseudo base station and the network side equipment is illegal equipment. The network side equipment forms a return value according to the characteristic number in the location updating request signaling, attaches the return value to the location updating response signaling, and returns the location updating response signaling to the terminal through the base station. The method of the embodiment of the disclosure realizes the identification of whether the base station is a pseudo base station, and also realizes the identification of whether the network side equipment is legal equipment. In the method, the information (such as the feature number) related to the identification is mainly mastered by the terminal, and the identification result is more accurate and reliable.
In some embodiments, before step S102, the method may further include: the terminal randomly generates N characteristic numbers and sends the N characteristic numbers to the network side equipment in the data interaction process with the network side equipment, wherein N is a positive integer. The network side device stores the N characteristic numbers.
For example, the terminal may generate a feature number after each startup or location update, and then send the feature number (for example, the feature number may be attached to a location update request signaling) to the network side device in the process of data interaction with the network side device, and the network side device stores the feature number. After N times of starting or position updating, the terminal generates N characteristic numbers, and performs data interaction with the network side equipment for N times, so that the N characteristic numbers are sent to the network side equipment. The network side device stores the N characteristic numbers. In addition, the terminal also stores the N feature numbers.
In some embodiments, the step of the terminal randomly generating the feature number after triggering the location update may include: the terminal randomly generates the (N + 1) th characteristic number after triggering position updating, and the position updating request signaling carries the (N + 1) th characteristic number. The terminal sends the location updating request signaling carrying the (N + 1) th characteristic number to the network side equipment through the base station.
In some embodiments, the step of the network side device forming the return value according to the characteristic number in the location update request signaling may include: and the network side equipment selects any one characteristic number from the stored N characteristic numbers as a return value according to the (N + 1) th characteristic number in the position updating request signaling.
In some embodiments, the step that the terminal determines whether the return value in the location update response signaling is a characteristic number formed according to a predetermined rule may include: the terminal judges whether the return value is any one of the N characteristic numbers. If the return value is any one of the N characteristic numbers (the terminal stores the N characteristic numbers), it indicates that the network side device is a legal device interacted with the terminal before, and it is determined that the base station is a legal base station and the network side device is a legal device; otherwise, the base station is determined to be a pseudo base station and the network side equipment is determined to be illegal equipment.
In the method for identifying the pseudo base station in the embodiment of the disclosure, when the location is updated, the terminal checks whether the feature number (i.e. the return value) returned by the network side device when passing through the base station at the next time is the feature number of another specific order sent by the terminal according to a group of ordered feature numbers grasped by the terminal, thereby judging the authenticity of the base station, which can effectively avoid the problem that the network side feature or information is imitated, and improve the reliability of pseudo base station identification.
In some embodiments, the method may further comprise: and under the condition that the base station is determined to be a legal base station and the network side equipment is determined to be legal equipment, the terminal and the network side equipment respectively store the (N + 1) th characteristic numbers, and respectively delete the characteristic numbers which are return values. In the embodiment, the characteristic numbers stored in the terminal and the network side equipment are updated, so that the subsequent identification of whether the base station is a pseudo base station is facilitated. Moreover, when the base station is determined to be a legal base station and the network side device is a legal device, since the feature number randomly selected from the N feature numbers as the return value has been used once, if the feature number is reused as the return value to perform another identification detection on the pseudo base station, the accuracy of the identification is reduced, so that the feature number which has been used as the return value is deleted, another sequence of feature numbers can be selected as the return value in another pseudo base station identification process, and the accuracy of the identification is improved.
In other embodiments, the method may further comprise: and when the base station is determined to be a pseudo base station and the network side equipment is determined to be illegal equipment, the terminal does not store the N +1 th characteristic number and does not delete any one of the N characteristic numbers. Thus, the N characteristic numbers are still used as the basis for identifying whether the base station is a pseudo base station or not next time.
In some embodiments, after the terminal performs judgment and identification on the base station and the network side device once, the terminal may further generate another sequence of feature numbers and send the feature numbers to the network side device through the base station when data interaction (for example, location update is triggered) next time, so as to perform identification and judgment again through the above process.
In some embodiments, the terminal may further randomly generate the feature number multiple times to check whether the base station and the network side device are the pseudo base station and the illegal device, respectively, multiple times. In this embodiment, a plurality of data interaction processes are performed to form a plurality of alternate verifications for the authenticity of the base station.
Fig. 2 is a flow chart illustrating methods for identifying a pseudo base station according to further embodiments of the present disclosure.
In step S202, the terminal randomly generates a feature number after triggering location update, attaches the feature number to a location update request signaling, and sends the location update request signaling to the currently camped base station.
In some embodiments, before this step S202, the method may further include: the terminal randomly generates N characteristic numbers and sends the N characteristic numbers to the network side equipment in the data interaction process with the network side equipment, wherein N is a positive integer. The network side device stores the N characteristic numbers. For example, each time the terminal is first powered on, a feature number may be generated and attached to a signaling (e.g., a location update request signaling), and since the base station where the terminal resides is generally a legal base station when the terminal is first powered on, the signaling carrying the feature number may be sent to the network side device through the known legal base station. The network side device may store the characteristic number in the signaling, and the characteristic number may be used as a return value for identification check. And the network side device may form a return value pool with all stored feature numbers.
In some embodiments, this step S202 may include: the terminal randomly generates the (N + 1) th characteristic number after triggering the position updating, and the position updating request signaling carries the (N + 1) th characteristic number. For example, the location update request signaling may include: MM (Mobile Management) Location Update Request message (Location Update Request) and/or MAP (Mobile Application Part) Update Location Request message (MAP Update Location Request). For example, when data interaction is performed at a certain time, the user terminal attaches the (N + 1) th feature number to an MM location update request message or a MAP update location request message, and sends the MM location update request message or the MAP update location request message to a base station where the terminal currently resides.
In step S204, the base station forwards the location update request signaling to the network side device.
For example, the network side device may include an MSC (Mobile Switch Center) or a VLR (Visitor Location Register). For example, the base station may send an MM location update request message (as location update request signaling) to the MSC or the VLR, where the MM location update request message carries the terminal-generated signature number.
For another example, the network-side device may further include an HLR (Home Location Register). For example, the MSC or the VLR may send a MAP update location request message (as location update request signaling) to the HLR, where the MAP update location request message carries the terminal generated feature number.
In step S206, the network side device forms a return value according to the characteristic number in the location update request signaling, attaches the return value to the location update response signaling, and returns the location update response signaling to the terminal through the base station.
In some embodiments, this step S206 may include: and the network side equipment selects any one characteristic number from the stored N characteristic numbers as a return value according to the (N + 1) th characteristic number in the position updating request signaling. For example, the ith characteristic number can be selected as a return value, i is more than or equal to 1 and less than or equal to N, and i is a positive integer. And then, the network side equipment sends a location updating response signaling to the base station where the terminal currently resides, wherein the location updating response signaling carries the return value. The base station forwards the location update response signaling to the terminal.
For example, the location update response signaling may include: a MAP Update Location Response message (MAP Update Location Response) and/or an MM Location Update Accept message (MM Location Update Accept). For example, the HLR selects any one of the N stored feature numbers as a return value (e.g., randomly or in a stored order) according to the N +1 th feature number in the MAP update location request message (as a location update request signaling), attaches the return value to the MAP update location response message (as a location update response signaling), and sends the MAP update location response message carrying the return value to the MSC or VLR. After receiving the MAP update location response message, the MSC or the VLR sends an MM location update accept message (as a location update response signaling) to the terminal through the base station, wherein the MM location update accept message carries the return value.
In step S208, the terminal determines whether the return value in the location update response signaling is a characteristic number formed according to a rule agreed in advance. If so, the process proceeds to step S210, otherwise, the process proceeds to step S212.
In some embodiments, this step S208 may include: and the terminal judges whether the return value is any one of the N characteristic numbers. For example, the user terminal determines whether the ith feature number as the return value matches any one of the N feature numbers stored in the terminal itself, for example, the terminal determines that the ith feature number matches the ith feature number in the N stored feature numbers, the process proceeds to step S210, otherwise, the process proceeds to step S212.
In step S210, the terminal determines that the base station is a legal base station and the network side device is a legal device.
In step S212, the terminal determines that the base station is a pseudo base station and the network side device is an illegal device.
In the above embodiment, the terminal randomly generates the feature number after triggering the location update, attaches the feature number to the location update request signaling, and sends the location update request signaling to the network side device through the currently residing base station; the network side equipment forms a return value according to the characteristic number in the position updating request signaling, attaches the return value to the position updating response signaling, and returns the position updating response signaling to the terminal through the base station; and the terminal judges whether the return value in the position updating response signaling is a characteristic number formed according to a predetermined rule, if so, the base station is determined to be a legal base station and the network side equipment is legal equipment, otherwise, the base station is determined to be a pseudo base station and the network side equipment is illegal equipment. The method of the embodiment of the disclosure realizes the identification of whether the base station is a pseudo base station and whether the network side equipment is illegal equipment. In the method, the information (such as the feature number) related to the identification is mainly mastered by the terminal, and the identification result is more accurate and reliable.
Furthermore, the method realizes the identification and verification of the base station and the network side equipment by comparing the characteristic numbers and the return values in different orders without carrying out complex data operation, and has high verification efficiency. In addition, the identification method of the embodiment of the disclosure can utilize the remaining signaling in the authentication process to incidentally identify the true and false characteristic number of the base station, and does not additionally occupy network resources.
In some embodiments, the method may further comprise: when the base station is determined to be a legal base station and the network side device is determined to be a legal device, the terminal and the network side device (e.g., HLR) respectively store the (N + 1) th feature number, and the terminal and the network side device respectively delete the feature number as a return value. The method realizes the updating of the characteristic number, and is favorable for ensuring the accuracy of the next identification and verification of the base station and the network side equipment.
In other embodiments, the method may further comprise: and when the base station is determined to be a pseudo base station and the network side equipment is determined to be illegal equipment, the terminal does not store the N +1 th characteristic number and does not delete any one of the N characteristic numbers.
In some embodiments, the method may further comprise: and the terminal randomly generates the characteristic number for multiple times so as to check whether the base station and the network side equipment are respectively a pseudo base station and illegal equipment for multiple times. In this embodiment, the terminal may randomly generate the feature number multiple times, so as to generate multiple feature numbers, and the identification verification may be performed again through the above steps S202 to S212 every time the feature number is generated, so that smooth and natural alternate mutual verification may be implemented in multiple data interaction processes, and the accuracy of pseudo base station identification is further improved.

The receiving unit 306 may be configured to receive a location update response signaling returned from a network side device, where the location update response signaling carries a return value.
The determining unit 308 may be configured to determine whether a return value in the location update response signaling is a feature number formed according to a predetermined rule, if so, determine that the base station is a legal base station and the network side device is a legal device, otherwise, determine that the base station is a fake base station and the network side device is an illegal device.
The base station forwards the location updating request signaling to the network side equipment; the network side equipment forms a return value according to the characteristic number in the location updating request signaling, attaches the return value to the location updating response signaling, and returns the location updating response signaling to the terminal through the base station.
The terminal of the embodiment of the disclosure realizes the identification and verification of whether the base station is a pseudo base station or not, and also realizes the identification and verification of whether the network side equipment is illegal equipment or not. Since the information (e.g., feature number) related to the recognition is mainly grasped by the terminal, the recognition result is more accurate and reliable.
In some embodiments, the feature number generating unit 302 may be configured to randomly generate N feature numbers, and send the N feature numbers to a network-side device during data interaction with the network-side device, where N is a positive integer. The network side device stores the N characteristic numbers. The feature number generation unit 302 may also have a storage function, for example, the N feature numbers may be stored.

In some embodiments, the terminal 30 may be configured to determine whether the return value is any one of the N characteristic numbers. If so, the terminal 30 determines that the base station is a legal base station and the network side device is a legal device, otherwise, determines that the base station is a pseudo base station and the network side device is an illegal device.
In some embodiments, in a case where the base station 32 is determined to be a legal base station and the network side device 34 is determined to be a legal device, the terminal 30 and the network side device 34 respectively store the N +1 th characteristic numbers, and the terminal 30 and the network side device 34 respectively delete the characteristic numbers as return values.
In other embodiments, when the base station 32 is determined to be a pseudo base station and the network side device 34 is determined to be an illegal device, the terminal 30 does not save the N +1 th feature number and does not delete any one of the N feature numbers.
In some embodiments, the terminal 30 may be configured to randomly generate the feature number multiple times to check whether the base station 32 and the network side device 34 are a fake base station and an illegal device, respectively.
