Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If relays or small cells are installed to acquire UE location information, then location measurement capability is improved, but device complexity and installation cost increase
Solution Approach 1:
The patent creates a virtual base station that copies and simulates base station signaling behaviors. Instead of installing physical relays or small cells, the system uses software to replicate base station functions, allowing third parties to measure UE location by analyzing uplink signals as if they were coming from a real base station, thereby avoiding complex hardware installations while maintaining measurement capability
Solution Approach 2:
The patent replaces the mechanical/physical installation of relays and small cells with an information-processing approach. The virtual base station uses signal processing and control information analysis to achieve location measurement without physical infrastructure, substituting hardware-based solutions with software-based signal manipulation and analysis
2Loss of information
If conventional communication devices are used, then network compatibility is maintained, but ability to acquire uplink signal information is lost
Solution Approach 1:
The patent makes the communication device universal by enabling it to perform both conventional downlink reception and uplink signal monitoring functions. The device can operate in dual modes: receiving normal downlink communications and simultaneously capturing uplink signals from UEs, thereby achieving multi-functionality without sacrificing conventional communication capabilities
Solution Approach 2:
The patent introduces control information as an intermediary element. By receiving and analyzing control information from the base station, the device gains insight into uplink resource allocations and uses this intermediary data to identify and capture relevant uplink signals, enabling indirect access to uplink information through a mediating control channel
3Adaptability or versatility
If third parties attempt to acquire UE location information, then public service capability is improved, but network influence and complexity increase
Solution Approach 1:
The patent enables third parties to create a virtual base station that copies base station control signaling. By replicating the base station's control information transmission, third-party devices can monitor UE uplink signals and extract location data without modifying the actual communication network, achieving public service functionality through software-based signal replication rather than complex network integration
Solution Approach 2:
The patent replaces the need for complex network infrastructure modifications with information-processing techniques. Third parties can acquire location information by analyzing control information and uplink signals through software algorithms, substituting hardware-based network modifications with computationally-based signal analysis, thereby reducing system complexity while maintaining public service capability
