Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems in cellular networks struggle to ensure suitable communication for mobile terminals with edge servers, particularly when there is a reduction in communication quality for specific traffic types.
Innovation Solution
A communication control device and method that dynamically switches the communication partner of a mobile terminal from a first edge server to a second edge server in a cellular network when a switching condition based on reduced communication quality is met, ensuring seamless communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile terminal communicates with a fixed edge server, then the communication path is stable, but the communication quality deteriorates when the edge server becomes congested or the terminal moves to a different location
Solution Approach 1:
The patent implements dynamic edge server selection by continuously monitoring communication quality metrics (delay, throughput, packet loss) and automatically switching between edge servers based on real-time conditions. The communication control device dynamically adjusts the communication path from a static edge server connection to an adaptive multi-edge server architecture, resolving the contradiction between stability and adaptability.
Solution Approach 2:
The system changes communication parameters (edge server selection, transmission power, modulation scheme) based on monitored quality metrics. When communication quality deteriorates below a threshold, the system transitions parameters to select an alternative edge server, thereby maintaining reliable communication while adapting to changing network conditions.
2Reliability
If the system switches edge servers frequently to maintain communication quality, then communication reliability improves, but system complexity increases due to multiple edge server management
Solution Approach 1:
The patent introduces a communication control device as an intermediary between mobile terminals and edge servers. This intermediary monitors communication quality, manages edge server selection, and handles switching decisions, thereby reducing the complexity burden on individual components while maintaining high communication reliability through coordinated multi-edge server management.
3Reliability
If the system monitors communication quality continuously to detect switching conditions, then communication reliability improves, but energy consumption increases
Solution Approach 1:
The system implements partial monitoring by focusing quality assessment on critical metrics (delay, throughput, packet loss) rather than comprehensive analysis of all communication parameters. Switching decisions are triggered only when quality deteriorates below predefined thresholds, avoiding excessive monitoring actions while maintaining sufficient communication reliability.

AI summary
A communication control device includes a processor configured to control switching of a partner of communication with a mobile terminal for first traffic from a first edge server to a second edge server in a cellular network when a switching condition for the first traffic based on a reduction in quality of communication related to the first traffic at present or in future is met and a second edge server capable of taking over the communication related to the first traffic is discovered in a state in which the mobile terminal is performing communication related to the first traffic and second traffic with the first edge server via the cellular network, an allowable delay for the second traffic being longer than an allowable delay for the first traffic.
