Abstract
The present disclosure provides an apparatus and method for detecting and responding to radio frequency jamming attacks in an Open RAN environment. An O-DU generates physical layer data including SNR, CQI, BLER, or MCS and transmits the data to a Near-RT RIC through an E2 interface. The Near-RT RIC stores the physical layer data in an SDL. An RF jamming detection xApp receives the physical layer data from the SDL to detect radio frequency jamming attacks. The xApp transmits the detected attack information to a network slice management rApp of a Non-RT RIC through an O1 interface to enable dynamic response through network slicing.

An apparatus for detecting radio frequency jamming attacks in an Open Radio Access Network (Open RAN) environment, the apparatus comprising:
- an Open RAN Distributed Unit (O-DU);
- and
- a control unit connected to the O-DU through an E2 interface and including a Near-Real-Time RAN Intelligent Controller (Near-RT RIC),
- wherein the O-DU generates physical layer data including at least one of Signal-to-Noise Ratio (SNR), Channel Quality Indicator (CQI), Block Error Rate (BLER), or Modulation and Coding Scheme (MCS), and transmits the physical layer data to the Near-RT RIC through the E2 interface, and
- wherein the Near-RT RIC is configured to store the physical layer data in a Shared Data Layer (SDL) through an internal messaging infrastructure and execute an RF jamming detection xApp configured to detect radio frequency jamming attacks based on data stored in the SDL.
A method for detecting and responding to radio frequency jamming attacks in an Open Radio Access Network (Open RAN) environment, the method comprising:
- generating, by an Open RAN Distributed Unit (O-DU), physical layer data including at least one of Signal-to-Noise Ratio (SNR), Channel Quality Indicator (CQI), Block Error Rate (BLER), or Modulation and Coding Scheme (MCS);
- transmitting, by the O-DU, the physical layer data to a Near-Real-Time RAN Intelligent Controller (Near-RT RIC) through an E2 interface;
- storing, by the Near-RT RIC, the physical layer data in a Shared Data Layer (SDL);
- receiving, by a Radio Frequency (RF) jamming detection xApp, the physical layer data from the SDL to detect radio frequency jamming attacks;
- and
- transmitting, by the RF jamming detection xApp, detected jamming attack information to a network slice management rApp of a Non-Real-Time RAN Intelligent Controller (Non-RT RIC) through an O1 interface.
An apparatus for responding to radio frequency jamming attacks in an Open Radio Access Network (Open RAN) environment, the apparatus comprising:
- a Non-Real-Time RAN Intelligent Controller (Non-RT RIC);
- and
- a Near-Real-Time RAN Intelligent Controller (Near-RT RIC) connected to the Non-RT RIC through an O1 interface,
- wherein the Non-RT RIC executes a network slice management rApp configured to receive jamming attack information, identify affected network slices, and establish response policies, and
- wherein the Near-RT RIC executes a slicing control xApp configured to receive the response policies, generate slicing control commands, and transmit the slicing control commands to an Open RAN Centralized Unit (O-CU) and an Open RAN Distributed Unit (O-DU) through an E2 interface.
