CN-122003899-A - Wireless location security breach detection and prevention

Abstract

A first User Equipment (UE) may send a first ranging message. The second UE may receive the first ranging message. The second UE may calculate a Carrier Frequency Offset (CFO) based on the ranging message. The second UE may transmit a response message including control information for modifying the transmission protocol. The sending of the response message may be in response to the calculated CFO being greater than or equal to a threshold. The calculated CFO may indicate a possible security hole between the first UE and the second UE. The first UE may receive a response message including control information for modifying a transmission protocol after transmission of the first ranging message. The first UE may then send a second ranging message based on the control information. The second ranging message may prevent or mitigate a detected possible security breach.

Description

Wireless location security breach detection and prevention Cross Reference to Related Applications The present application claims the benefit of U.S. non-provisional patent application serial No. 18/492,711, entitled "SECURITY VULNERABILITY DETECTION AND PREVENTION FOR WIRELESS POSITIONING (wirelessly located security breach detection and prevention)" filed on day 10/23 of 2023, which is expressly incorporated herein by reference in its entirety. Technical Field The present disclosure relates generally to communication systems, and more particularly to wireless positioning systems. Background Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcast. A typical wireless communication system may employ multiple-access techniques capable of supporting communication with multiple users by sharing the available system resources. Examples of such multiple-access techniques include Code Division Multiple Access (CDMA) systems, time Division Multiple Access (TDMA) systems, frequency Division Multiple Access (FDMA) systems, orthogonal Frequency Division Multiple Access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, and time division synchronous code division multiple access (TD-SCDMA) systems. These multiple access techniques have been employed in various telecommunications standards to provide a common protocol that enables different wireless devices to communicate at the urban, national, regional, and even global levels. One example telecommunications standard is 5G New Radio (NR). The 5G NR is part of the ongoing mobile broadband evolution promulgated by the third generation partnership project (3 GPP) to meet new requirements associated with latency, reliability, security, scalability (e.g., with the internet of things (IoT)) and other requirements. The 5G NR includes services associated with enhanced mobile broadband (eMBB), large-scale machine-type communications (mMTC), and ultra-reliable low-latency communications (URLLC). Some aspects of 5G NR may be based on the 4G Long Term Evolution (LTE) standard. Further improvements in the 5G NR technology are needed. Furthermore, these improvements may also be applicable to other multiple access techniques and telecommunication standards employing these techniques.
