Communication Apparatus Selective Network List Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face congestion issues in mobile communication networks when a disaster occurs, as a large number of communication terminals attempt to access alternative networks simultaneously.
Innovation Solution
A communication apparatus and method that selectively transmit list information of available networks during a disaster only to terminal apparatuses associated with high-priority identification information, preventing unnecessary access and congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If list information is transmitted to all terminal apparatuses, then terminal apparatuses can access alternative networks when a disaster occurs, but traffic in the alternative network rapidly increases and congestion occurs
Solution Approach 1:
The patent applies local quality by differentiating the treatment of list information transmission based on terminal apparatus priority. High-priority terminal apparatuses receive list information to enable alternative network access, while low-priority terminal apparatuses do not receive the information, thereby preventing unnecessary traffic generation. This selective information distribution resolves the contradiction by tailoring network behavior to individual terminal characteristics.
2Quantity of substance
If list information is transmitted to high-priority terminal apparatuses only, then congestion in alternative network is prevented, but low-priority terminal apparatuses cannot access alternative networks
Solution Approach 1:
The patent implements local quality by creating different information access rights based on terminal priority levels. High-priority terminals receive list information enabling alternative network access during disasters, while low-priority terminals are deliberately excluded from receiving this information. This differentiation prevents network congestion while ensuring that critical terminals maintain access capabilities.
3Quantity of substance
If identification information is used to differentiate terminal priority, then selective list information transmission is enabled, but system complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring terminal apparatuses with identification information that indicates their priority level before disasters occur. The network side apparatuses have pre-established criteria for determining high-priority versus low-priority terminals. This pre-prepared state enables rapid selective list information transmission during disasters without requiring complex real-time analysis, thus reducing operational complexity while maintaining traffic control effectiveness.

AI summary
An object is to provide a communication apparatus capable of preventing a rapid increase in traffic in a mobile communication network capable of providing a communication service when a disaster occurs. A communication apparatus (1) according to the present disclosure includes: a transmission unit (2) configured to transmit list information indicating networks that are available when a disaster occurs in a case where identification information of a terminal apparatus is associated with a high-priority terminal, and configured not to transmit the list information in a case where the identification information is not associated with the high-priority terminal.
