Abstract

Disclosed are a method and device for handling a pseudo base station. The method includes: performing restriction processing on a registration network of the mobile terminal at the pseudo base station in response to determining a pseudo base station; and prohibiting accessing the pseudo base station in response to the restriction processing.

First claim

What is claimed is:

1. A method for handling a pseudo base station, for a mobile terminal, comprising:
attempting registration of the mobile terminal at the pseudo base station;
obtaining a registration attempt number of the mobile terminal at the pseudo base station;
determining whether the registration attempt number exceeds a preset number;
prohibiting accessing the pseudo base station in response to a determination that the registration attempt number exceeds the preset number;
detecting a duration of prohibiting accessing the pseudo base station;
comparing the duration of prohibiting accessing the pseudo base station with a preset duration stored locally by the mobile terminal;
determining whether the pseudo base station is from a security monitoring system based on a feature parameter, wherein the feature parameter comprises at least one of a tracking area identity (TAI), an eutra absolute radio frequency channel number (EARFCN), a physical cell identity (PCI), or a cell identity (CID); and
in response to a determination that the duration exceeds the preset duration and a determination that the pseudo base station is from the security monitoring system, allowing accessing the pseudo base station to report information to the security monitoring system.

2. The method of claim 1 , wherein the preset number is zero.

3. The method of claim 1 , further comprising:
displaying a prompt message during the preset duration of prohibiting accessing the pseudo base station.

4. The method of claim 3 , further comprising:
continuing to access the pseudo base station in response to a target action based on the prompt message.

5. The method of claim 1 , further comprising:
configuring to maintain a 4G network connection during the preset duration of prohibiting accessing the pseudo base station.

6. The method of claim 1 , further comprising:
detecting the base station and obtaining identification information of detected base stations; and
preferably accessing base stations except the pseudo base station among the detected base stations in response to the identification information of the detected base stations comprising identification information of the pseudo base station.

7. The method of claim 6 , wherein preferably accessing base stations except the pseudo base station among the detected base stations in response to the identification information of the detected base stations comprising identification information of the pseudo base station comprises:
obtaining the base stations except the pseudo base station among the detected base stations in response to the identification information comprising identification information of the pseudo base station;
determining a target base station having the longest access time with the mobile terminal from the obtained base stations; and
accessing the target base station.

8. The method of claim 6 , further comprising:
obtaining identification information of the pseudo base station, and adding the identification information to a preset list.

9. The method of claim 1 , further comprising:
receiving a rejection code rejecting a registration network of the mobile terminal from the pseudo base station;
determining the rejection code as a preset rejection code; and
rejecting the registration network of the mobile terminal based on the preset rejection code.

10. The method of claim 9 , wherein, rejecting the registration network of the mobile terminal based on the preset rejection code, comprises:
prohibiting detecting a feature parameter corresponding to the pseudo base station based on the preset rejection code; and
detecting feature parameters corresponding to the base stations except the pseudo base station.

11. A mobile terminal for handling a pseudo base station, comprising:
one or more processors;
a memory storing instructions executable by the one or more processors;
wherein the one or more processors are configured to:
attempt registration of the mobile terminal at the pseudo base station;
obtain a registration attempt number of the mobile terminal at the pseudo base station;
determine whether the registration attempt number exceeds a preset number;
prohibit accessing the pseudo base station in response to a determination that the registration attempt number exceeds the preset number;
detect a duration of prohibiting accessing the pseudo base station;
compare the duration of prohibiting accessing the pseudo base station with a preset duration stored locally by the mobile terminal;
determine whether the pseudo base station is from a security monitoring system based on a feature parameter, wherein the feature parameter comprises at least one of a tracking area identity (TAI), an eutra absolute radio frequency channel number (EARFCN), a physical cell identity (PCI), or a cell identity (CID); and
in response to a determination that the duration exceeds a preset duration and a determination being made that the pseudo base station is from the security monitoring system, allow accessing the pseudo base station to report information to the security monitoring system.

12. The mobile terminal of claim 11 , wherein the one or more processors are configured to:
receive a rejection code rejecting a registration network of the mobile terminal from the pseudo base station;
determine the rejection code as a preset rejection code; and
reject the registration network of the mobile terminal based on the preset rejection code.

13. The mobile terminal of claim 12 , wherein the one or more processors are configured to:
prohibit detecting a feature parameter corresponding to the pseudo base station based on the preset rejection code; and
detect feature parameters corresponding to the base stations except the pseudo base station.

14. A non-transitory computer readable storage medium, wherein the computer readable storage medium stores a program code, and the program code is called by a processor to execute a method for handling a pseudo base station, applied to a mobile terminal, and the method comprises:
attempting registration of the mobile terminal at the pseudo base station;
obtaining a registration attempt number of the mobile terminal at the pseudo base station;
determining whether the registration attempt number exceeds a preset number;
prohibiting accessing the pseudo base station in response to a determination that the registration attempt number exceeds the preset number;
detecting a duration of prohibiting accessing the pseudo base station;
comparing the duration of prohibiting accessing the pseudo base station with a preset duration stored locally by the mobile terminal;
determining whether the pseudo base station is from a security monitoring system based on a feature parameter, wherein the feature parameter comprises at least one of a tracking area identity (TAI), an eutra absolute radio frequency channel number (EARFCN), a physical cell identity (PCI), or a cell identity (CID); and
in response to a determination that the duration exceeds the preset duration and a determination that the pseudo base station is from the security monitoring system, allowing accessing the pseudo base station to report information to the security monitoring system.
