Solution Overview
Problem
Existing wireless communication systems face challenges in managing activity information of wireless communication terminals when they cannot communicate with a wireless base station, leading to potential communication band congestion due to simultaneous transmission of stored data.
Innovation Solution
A communication terminal device with dual communication units and control mechanisms to determine communication feasibility, store data during failures, and transmit aggregated information upon recovery, reducing simultaneous transmission during failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple wireless communication terminals transmit temporarily stored activity information to a management server simultaneously when wireless communication is restored, then the activity information can be successfully delivered, but communication band congestion occurs and communication lines are strained
Solution Approach 1:
The patent introduces a representative terminal as an intermediary that collects activity information from multiple terminals and transmits it centrally to the management server. This mediator approach prevents simultaneous transmissions by consolidating data through a single designated terminal, thereby delivering reliable information while avoiding communication band congestion.
Solution Approach 2:
The patent implements preliminary actions by having terminals store activity information locally in advance when wireless communication is unavailable. The representative terminal also pre-establishes its role before communication restoration occurs. This preliminary data accumulation and role assignment enable efficient centralized transmission once connectivity is restored, preventing congestion while ensuring complete information delivery.
2Loss of information
If wireless communication terminals store activity information locally during communication failures, then information can be transmitted when connectivity is restored, but communication lines become strained due to simultaneous transmissions from multiple terminals
Solution Approach 1:
The patent merges the transmission functions of multiple terminals by designating one representative terminal to consolidate and forward all activity information. Instead of each terminal transmitting separately (which strains communication lines), their data streams are combined through the representative terminal, preserving all information while reducing overall transmission load on the communication network.
Solution Approach 2:
The representative terminal serves as an intermediary that receives stored activity information from multiple terminals and forwards it to the management server. This intermediary function prevents direct simultaneous transmissions between multiple terminals and the server, thereby preserving information integrity while avoiding communication line strain through centralized data flow management.
3Object-affected harmful factors
If a representative terminal is designated to aggregate and transmit information centrally, then communication band congestion is avoided, but device complexity increases due to additional determination and control mechanisms
Solution Approach 1:
The patent implements self-service by having terminals autonomously determine their own representative status based on predefined criteria without requiring external assignment. Each terminal independently evaluates conditions and selects itself as representative when appropriate, eliminating the need for complex centralized assignment mechanisms while still achieving congestion avoidance through decentralized self-organization.

AI summary
A communication terminal device includes a first communication unit that performs information communication with a management device, a second communication unit that performs the information communication with another communication terminal device, a communication determination unit that determines whether or not the information communication performed by the first communication unit is possible, a role determination unit that determines a role of the own communication terminal device, a first communication control unit that controls the first communication unit, and a second communication control unit that controls the second communication unit. In a case where the information communication to be performed by the first communication unit is impossible, and also, in a case where the own communication terminal device is not a representative terminal, the second communication control unit transmits the information that is to be transmitted to the management device to the other communication terminal device. In a case where the information communication to be performed by the first communication unit is impossible, and also, in a case where the own communication terminal device is the representative terminal, the first communication control unit stores the information that is to be transmitted to the management device and the information that has been received from the other communication terminal device in the storage unit, and transmits the information stored in the storage unit to the management device when the information communication to be performed by the first communication unit becomes possible.
