Emergency Call Mode Selection for Communication Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of communication terminals face difficulties in accessing emergency services while traveling internationally due to varying emergency phone numbers and call modes across countries, leading to potential delays in receiving necessary services.
Innovation Solution
A method and apparatus that determine the current country or region of a communication terminal using cell system information and retrieve the appropriate call mode from a storage region to connect with an emergency call center, allowing users to select an emergency call category for seamless and efficient emergency service access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If emergency call protocols follow local country-specific rules, then emergency services can be accessed using local numbers, but users traveling internationally face confusion and delays due to varying emergency numbers and call modes across different countries
Solution Approach 1:
The patent implements a universal emergency call processing mechanism that automatically adapts to different countries' emergency call protocols. The system retrieves current location information, queries a database for the corresponding country's emergency call rules, and automatically configures the appropriate call mode and destination number. This allows a single device to handle multiple countries' emergency call requirements without user intervention, resolving the contradiction between ease of operation and adaptability to different countries.
2Reliability
If the system stores comprehensive emergency call information for multiple countries and categories, then accurate emergency services can be provided, but the device complexity increases due to large storage requirements
Solution Approach 1:
The patent extracts the complex emergency call information database from the mobile device and stores it in a remote server or cloud platform. The device only maintains a lightweight local cache for frequently accessed information and automatically synchronizes with the remote database when needed. This extraction approach maintains high reliability by accessing comprehensive emergency call information while significantly reducing device complexity and storage requirements.
Solution Approach 2:
The patent introduces an intermediary emergency call information management system that acts as a mediator between the user's device and the comprehensive emergency call database. This intermediary layer handles the complexity of storing and managing emergency call information for multiple countries and categories, while providing simplified access to the device. The intermediary can be implemented as a remote server or cloud service that the device queries when emergency call information is needed.

AI summary
A method and an apparatus for processing an emergency call of a communication terminal are provided. The method includes: obtaining current country or region information based on resident cell system information of the communication terminal; when an emergency request, which contains an emergency call category requested by a user, is received, retrieving a first storage region based on the current country or region information and the requested emergency call category to determine a call mode corresponding to the requested emergency call category in the current country or region, where the first storage region stores call modes corresponding to multiple emergency call categories and multiple countries and regions; and connecting with an emergency call center based on the determined call mode. Accordingly, users of the communication terminal can get emergency services conveniently, promptly and efficiently no matter which country or region he or she resided.
