WIRELESS CHANNEL POWER PROFILE FALSE BASE STATION DETECTION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18527167 titled 'WIRELESS CHANNEL POWER PROFILE FALSE BASE STATION DETECTION
Simplified Explanation
The abstract of the patent application describes a method for a user equipment (UE) to detect a false base station (FBS) in a wireless access network by estimating the time of arrival of different multipath components of a downlink signal and determining the existence of an FBS based on the difference between the times of arrival of two components exceeding a threshold amount of time.
- Explanation of the patent/innovation:
- UE detects FBS by estimating time of arrival of multipath components. - UE determines FBS existence based on the difference in arrival times exceeding a threshold. - UE performs mitigation operation upon detecting FBS.
Potential applications of this technology
- Enhancing security in wireless access networks. - Preventing unauthorized access to network resources.
Problems solved by this technology
- Mitigating the risk of unauthorized access by FBS. - Ensuring data integrity and privacy in wireless communications.
Benefits of this technology
- Improved network security. - Enhanced user privacy and data protection.
Potential commercial applications of this technology
- Telecommunications companies. - Network security firms.
Possible prior art
- Prior art may include methods for detecting unauthorized base stations in wireless networks. - Existing techniques for enhancing network security in wireless communications.
Unanswered questions
How does the UE differentiate between legitimate and false base stations in a crowded network environment?
The UE may use additional criteria such as signal strength, signal quality, and network authentication to distinguish between legitimate and false base stations.
What impact does the detection of an FBS have on network performance and user experience?
The detection of an FBS may lead to network disruptions, increased latency, and potential data breaches if not mitigated effectively. Network operators need to ensure minimal impact on network performance while maintaining security measures against FBS.
Original Abstract Submitted
In a wireless access network, a false base station (FBS) may imitate a legitimate base station by repeating the transmissions of the legitimate base station at a higher power level such that one or more user equipment (UEs) synchronize with the FBS instead of the legitimate base station. The present disclosure provides a UE that detects an FBS. The UE may estimate a time of arrival of different multipath components of a downlink signal corresponding to a physical cell identity. The UE may determine an existence of FBS based on a difference between the times of arrival of two of the different multipath components exceeding a threshold amount of time. The UE may perform a mitigation operation in response to determining the existence of the FBS.
