Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual drive tests are used for MBMS network optimization, then measurement data can be collected, but the cost increases and environmental emission rises
Solution Approach 1:
The patent implements self-service by enabling user equipments (UEs) to autonomously perform MBMS transmission quality measurements and automatically report results to the network. The UE independently executes measurement configurations, collects MDT data during idle or connected modes, and transmits reports without requiring manual drive test intervention, thereby eliminating the harmful environmental emissions associated with manual testing while maintaining measurement capabilities
Solution Approach 2:
The patent replaces the mechanical manual drive test system with an automated electronic measurement system. Instead of physically deploying personnel in vehicles to collect measurement data, the system substitutes this mechanical approach with electronic signal processing where UEs automatically measure MBMS transmission quality parameters (such as RSRP, RSRQ) and electronically report results, eliminating the need for physical movement and associated environmental impact

3Measurement precision
If manual drive tests are used for MBMS network optimization, then measurement data can be collected, but the efficiency decreases due to lack of real-time feedback
Solution Approach 1:
The patent implements feedback by establishing an automated closed-loop system where UEs continuously measure MBMS transmission quality and immediately report results to the network in real-time. The network receives these measurement reports and can promptly adjust transmission parameters, optimize MBSFN area configurations, and improve service quality without waiting for manual analysis, thereby significantly enhancing network optimization efficiency and productivity
Solution Approach 2:
The system performs preliminary action by pre-configuring UEs with measurement configurations before actual MBMS transmission occurs. The network provides MDT measurement configurations in advance, enabling UEs to prepare measurement routines and immediately begin collecting data when MBMS services are activated, thus eliminating delays associated with manual test setup and accelerating the optimization process

AI summary
A method of handling a multimedia broadcast multicast service (MBMS) minimization of driver test (MDT) for a network of a wireless communication system includes transmitting a first MBMS measurement configuration to instruct a first user equipment (UE) to perform an MBMS MDT operation; receiving a first MBMS measurement result and a first multicast-broadcast single frequency network (MBSFN) area identity (ID) which indicates that the first MBMS measurement result is generated for a first MBSFN area identified by the first MBSFN area ID, from the first UE; and processing the first MBMS measurement result according to the first MBSFN area ID.
