Solution Overview
Problem
Device-to-device communication in cellular networks faces interference issues, leading to inconveniences and communication failures, as existing technologies do not adequately consider various communication environments and may cause signal interference with surrounding cellular networks.
Innovation Solution
A mobile communication device with a processor configured to receive system information from a base station, connect to a cell, and trigger events indicating whether device-to-device communication is possible or impossible based on frequency band and radio resource information, ensuring minimal interference and user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If device-to-device communication is continuously attempted in a cellular network, then communication availability is improved, but signal interference with surrounding cellular network increases
Solution Approach 1:
The device performs preliminary actions by receiving system information from the base station before attempting device-to-device communication. This includes obtaining frequency band information and radio resource information about the cell, and determining whether device-to-device communication is possible based on this information, thereby preventing interference before it occurs
Solution Approach 2:
The system implements feedback by continuously monitoring system information from the base station regarding frequency bands and radio resources. When the device determines that device-to-device communication would cause interference (second event), it stops communication attempts. When conditions are favorable (first event), communication is permitted, creating a closed-loop control system that adapts to network conditions
2Speed
If device-to-device communication is enabled without checking communication environment, then communication speed is improved, but communication reliability deteriorates due to interference
Solution Approach 1:
Before enabling device-to-device communication, the device performs preliminary checks by receiving and analyzing system information from the base station, including frequency band information and radio resource information. This preliminary assessment ensures that communication is only enabled when network conditions are favorable, preventing interference-related failures
3Object-generated harmful factors
If device-to-device communication is restricted based on system information, then signal interference is reduced, but communication flexibility decreases
Solution Approach 1:
The system dynamically adjusts device-to-device communication permissions based on real-time system information from the base station. The device monitors frequency band information and radio resource information, and flexibly enables or disables communication according to current network conditions. This dynamic approach allows the system to adapt to changing environments rather than using fixed restrictions
