Base Station D2D Data Interception via Signaling Trigger
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication interception methods fail to intercept device-to-device (D2D) data effectively, as D2D communication bypasses traditional network pathways, making it difficult to intercept data without network carriage.
Innovation Solution
A communication interception method involving a base station and terminal that receives messages to instruct and record D2D data, allowing for the interception and transmission of D2D data directly between devices, utilizing messages to trigger data recording and reporting processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If D2D communication is implemented to enable direct data transmission between devices, then communication efficiency and speed are improved, but the ability to intercept communication data is lost
Solution Approach 1:
The base station serves as an intermediary that receives D2D data from the terminal and forwards it to the other party. This allows the data to bypass the traditional network core while still passing through a controllable node (the base station) that can facilitate lawful interception. The base station acts as a mediator that enables both direct communication and interception capabilities simultaneously.
Solution Approach 2:
The base station is designed to perform multiple functions: it facilitates D2D communication by relaying data between terminals while simultaneously maintaining the capability to intercept and forward this data to law enforcement or monitoring entities. This multi-functionality resolves the contradiction by making the same infrastructure serve both communication efficiency and security monitoring purposes.
2Reliability
If traditional network pathways are used for communication, then interception capability is maintained, but communication efficiency and speed deteriorate
Solution Approach 1:
The communication pathway is segmented into control signaling (which goes through the base station for interception) and data transmission (which can use direct D2D links for efficiency). This segmentation allows different parts of the communication system to use different pathways optimized for their specific purposes: speed for data, control for security.
Solution Approach 2:
The base station acts as an intermediary that receives D2D data from the terminal and forwards it to the other party. This allows the data to bypass the traditional network core while still passing through a controllable node (the base station) that can facilitate lawful interception. The base station acts as a mediator that enables both direct communication and interception capabilities simultaneously.
3Productivity
If D2D data is transmitted without network carriage, then communication efficiency is improved, but the ability to perform lawful interception is lost
Solution Approach 1:
The base station serves as an intermediary that receives D2D data from the terminal and forwards it to the other party. This allows the data to bypass the traditional network core while still passing through a controllable node (the base station) that can facilitate lawful interception. The base station acts as a mediator that enables both direct communication and interception capabilities simultaneously.
Solution Approach 2:
The system implements feedback mechanisms where the base station receives status information about D2D communications and adjusts its interception and forwarding operations accordingly. This ensures that intercepted data is properly captured and forwarded to authorized entities while maintaining the efficiency of D2D communication pathways.

AI summary
A communication interception method by a base station, a device and a terminal belonging to device-to-device (D2D) communication includes: receiving a message sent by a device, where the message is used to instruct interception of D2D data of the terminal belonging to the D2D communication; obtaining the D2D data according to the message; and sending the obtained D2D data to the device.
