Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the context of 5G wireless communication systems, providing high-quality services such as 4K and 8K moving images and ensuring fairness in communication quality among multiple users participating in simultaneous activities, like multiplayer games, is challenging due to differences in network configurations.
Innovation Solution
A control device that acquires information from multiple wireless communication devices regarding their communication details, including position information, application process IDs, and PLMN identifiers, and determines the execution of PLMN switching processing to equalize communication quality among users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple users connect via different PLMNs simultaneously, then network capacity and coverage are improved, but communication quality fairness deteriorates
Solution Approach 1:
The control device continuously monitors communication quality parameters (throughput, delay, packet loss) for each user and uses this feedback to dynamically adjust PLMN assignments. When quality degradation is detected in a user's current PLMN, the system switches the user to a different PLMN to restore fairness, creating a closed-loop control mechanism that maintains communication quality equity while allowing multiple simultaneous connections.
Solution Approach 2:
The system dynamically adjusts PLMN assignments based on real-time communication conditions rather than maintaining static assignments. The control device evaluates network status and user requirements continuously, switching PLMNs as needed to maintain fairness. This dynamic adaptation allows the network to optimize resource allocation and ensure equal quality of experience for all users regardless of their initial PLMN assignment.
2Reliability
If PLMN switching is implemented to ensure communication quality fairness, then communication quality equality is improved, but system complexity increases
Solution Approach 1:
A control device is introduced as an intermediary component between the network and users to manage PLMN switching. This dedicated control entity collects communication quality information from users, processes the data to determine fairness violations, and executes appropriate PLMN switching decisions. By centralizing this control function in a separate device, the complexity of PLMN management is isolated from individual user devices, making the overall system more manageable while achieving communication quality fairness.
3Reliability
If communication quality monitoring is performed for all users, then communication quality fairness is improved, but processing load increases
Solution Approach 1:
The system monitors and manages communication quality on a per-user basis, treating each user's connection independently. The control device collects quality metrics only for users experiencing potential fairness issues rather than uniformly processing all users regardless of status. This localized monitoring approach allows the system to maintain fairness by focusing resources on users who need attention, reducing overall processing load while ensuring fair treatment of affected users.
