MBMS-MDT Value Tag Reconfiguration in Wireless Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for reconfiguring Multimedia Broadcast Multicast Service (MBMS) Minimization of Drive Test (MDT) in wireless communication systems lack efficiency, as they do not provide a mechanism to dynamically adjust MBMS-MDT configurations only when necessary, leading to unnecessary resource utilization and increased costs.
Innovation Solution
A method for reconfiguring MBMS-MDT by using a value tag for MBMS-MDT configuration, where the User Equipment (UE) compares received and stored value tags to determine if reconfiguration is needed, and also by utilizing a paging message with an indicator of configuration modification to acquire and perform MBMS-MDT reconfiguration only when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If MBMS-MDT configuration is continuously updated and reconfigured, then the network can maintain up-to-date measurement parameters, but unnecessary resource utilization increases and costs rise
Solution Approach 1:
The patent introduces a value tag parameter that changes only when MBMS-MDT configuration is actually modified. The UE compares the received value tag with its stored value tag to determine whether reconfiguration is necessary, thereby avoiding continuous unnecessary updates and reducing resource utilization while ensuring the configuration remains up-to-date when changes occur.
2Adaptability or versatility
If MBMS-MDT reconfiguration is performed frequently, then the network can adapt to changing conditions, but unnecessary operations increase and costs increase
Solution Approach 1:
The patent implements partial action by performing MBMS-MDT reconfiguration only when necessary, as indicated by the value tag comparison. Instead of continuously or frequently reconfiguring, the system performs the reconfiguration operation only when the configuration has actually changed, thereby maintaining adaptability while avoiding excessive unnecessary operations and improving overall operation efficiency.
3Speed
If the UE continuously monitors for configuration updates, then the UE can respond to changes quickly, but power consumption and processing overhead increase
Solution Approach 1:
The patent implements periodic action through the value tag mechanism, where the UE monitors for configuration updates by comparing value tags at specific intervals or events rather than continuously. This approach allows the UE to maintain quick response capability when changes occur while significantly reducing power consumption and processing overhead compared to continuous monitoring.
Data Source
AI summary
A method and apparatus for reconfiguring multimedia broadcast multicast service (MBMS) minimization of drive test (MDT) in a wireless communication system is provided. A user equipment (UE) receives a value tag for MBMS-MDT, and determines whether to perform MBMS-MDT reconfiguration by comparing the received value tag for MBMS-MDT with a stored value tag for MBMS-MDT. If the received value tag for MBMS-MDT and the stored value tag for MBMS-MDT are different from each other, the UE performs the MBMS-MDT reconfiguration. Alternatively, if a paging message includes an indicator of modification of the MBMS-MDT configuration, the UE acquires the MBMS-MDT configuration and performs the MBMS-MDT reconfiguration.
