Wireless Terminal Special Account Activation Without Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During disasters like severe earthquakes, wireless terminals cannot send special messages without accessing the IM server system, as special accounts require server access, which may be unavailable, disrupting communication services for authorities needing to disseminate information widely.
Innovation Solution
A wireless terminal with a processor and transceiver that executes a communication service application, allowing normal and special account communications, and activates the special account through a predetermined procedure without server access, enabling special message transmission via a wireless multi-hop network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If special accounts use the IM server system for communication, then they can broadcast messages to many users, but they cannot send messages when the server system is unavailable during disasters
Solution Approach 1:
The patent segments the communication function into two independent paths: server-based communication for normal operations and peer-to-peer multi-hop communication for disaster scenarios. The special account functionality is separated from the server dependency, allowing it to operate independently through local wireless mesh networking when the server is unavailable.
Solution Approach 2:
The patent implements preliminary action by pre-configuring the wireless terminal with the capability to activate special accounts and establish multi-hop communication paths before disasters occur. The system prepares alternative communication routes in advance, so when the server becomes unavailable, the terminal can immediately switch to peer-to-peer messaging without requiring server access.
2Ease of operation
If wireless terminals use server-based IM services, then they can access communication services normally, but they cannot communicate when cellular network or WLAN facilities stop during disasters
Solution Approach 1:
The patent introduces wireless multi-hop communication as an intermediary mechanism that bridges the gap between isolated terminals during disasters. Instead of relying on the server as the sole intermediary, the system enables terminals to communicate through intermediate wireless nodes in the mesh network, allowing message transmission without server or infrastructure involvement.
Solution Approach 2:
The patent implements dynamics by making the communication architecture flexible and adaptive. The system can dynamically switch between server-based communication and peer-to-peer multi-hop communication based on server availability. The wireless mesh network topology dynamically adjusts to maintain communication paths as nodes move or fail during disaster conditions.

AI summary
A processor (103) in a wireless terminal (10) executes a communication service application to thereby perform an operation as a client for using a communication service. Further, in an abnormal situation where the wireless terminal (10) cannot access a server system (50) of an operator of the communication service, the processor (103) executes a predetermined activation procedure in the wireless terminal (10) without passing through the server system (50) to thereby activate a special account in the wireless terminal (10). This makes it possible, for example, to perform communication by the special account using an online service application installed in the wireless terminal during an abnormal situation where the wireless terminal cannot access the online service server.
