Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional drive tests are conducted to optimize MBMS service areas, then measurement information can be collected, but the complexity and cost of drive tests increases significantly
Solution Approach 1:
The patent creates virtual copies of drive test functionality by implementing measurement logging and reporting capabilities directly in user terminals. Instead of requiring physical drive test equipment, the system uses terminal devices to collect and report MBMS measurement information, thereby copying the essential measurement function in a simpler, more scalable manner.
Solution Approach 2:
The patent enables terminals to automatically perform measurement logging and reporting without requiring external drive test equipment or manual intervention. The terminals self-configure based on received configuration information, automatically log MBMS-related measurements, and autonomously report the data to the base station, making the system self-sufficient for optimization purposes.
2Measurement precision
If traditional drive tests are conducted to optimize MBMS service areas, then service area optimization can be achieved, but the time required for optimization increases
Solution Approach 1:
The patent enables continuous measurement logging and reporting by terminals in the background during normal MBMS operations. Rather than requiring separate, time-consuming drive test campaigns, the system continuously collects measurement data as users naturally access MBMS services, eliminating downtime and making the optimization process ongoing and uninterrupted.
Solution Approach 2:
The patent pre-configures terminals with measurement logging capabilities and configuration information from the base station before actual MBMS service deployment. This preliminary setup allows terminals to immediately begin collecting relevant measurement data when MBMS services are activated, eliminating the need for subsequent time-consuming drive test phases.
3Measurement precision
If traditional drive tests are conducted to optimize MBMS service areas, then measurement data can be obtained, but the cost of wireless optimization and management increases
Solution Approach 1:
The patent makes terminal devices perform multiple functions: they serve as both regular MBMS receivers and as measurement collection instruments. By utilizing existing terminal hardware and software for dual purposes, the system eliminates the need for separate expensive drive test equipment, thereby reducing optimization costs while maintaining measurement capabilities.
Solution Approach 2:
The patent enables terminals to autonomously perform measurement logging and reporting without requiring external drive test equipment or specialized optimization tools. This self-service approach eliminates the need for costly external optimization services and reduces the overall expenditure on wireless optimization and management infrastructure.
