Emergency Location Data Transmission via Dual Communication Sessions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices may fail to receive location information in time during emergency calls due to interference and obstructions in the radio wave environment, or heavy system loads, which can lead to terminated calls before location information is received by emergency stations, hindering responder dispatch.
Innovation Solution
An electronic device establishes a first communication session for a voice call and requests location information from a server, and upon detecting an emergency call input, it establishes a second communication session to transmit the received location information to the emergency station using short-range wireless communication, ensuring timely location data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the user terminal transmits a request for location information to the emergency call server before making an emergency call, then the location information can be obtained in advance, but the call may be terminated before location information is received due to heavy system load or radio wave interference
Solution Approach 1:
The patent applies preliminary action by establishing a communication session and transmitting a location information request before the emergency call is made. The system proactively requests location data in advance, and if received, stores it for subsequent transmission to the emergency station, ensuring location information is available even if the initial request timing is suboptimal
Solution Approach 2:
The patent uses an intermediary approach by introducing a separate communication session between the user terminal and the emergency call server that is distinct from the emergency call itself. This intermediary session allows location information to be exchanged independently, so that failure or termination of the emergency call does not prevent location information from being transmitted and received
2Speed
If the emergency call is made immediately without waiting for location information, then the response time is reduced, but the location information may not be available when needed by emergency responders
Solution Approach 1:
The system performs preliminary action by requesting location information as soon as the emergency call session is established, before the call is fully active. If the location information is received during this preliminary phase, it is stored and automatically transmitted to the emergency station, ensuring both rapid response and complete information delivery
Solution Approach 2:
The patent maintains continuity of useful action by keeping the communication session open and continuously attempting to receive location information throughout the emergency call process. Even if the initial request fails, the system continues to monitor for location data and transmits it as soon as it becomes available, ensuring uninterrupted effort to deliver location information

AI summary
An electronic device and method are disclosed. The electronic device includes a processor which implements the method, including establishing a first communication session for a voice call with a first external electronic device using a short-range wireless communication module operably connected to the electronic device, transmitting a request for location information of the electronic device to a second external electronic device via the short-range wireless communication module, when a response to the request is not received from the second external electronic device and when an input is detected requesting an emergency call, establishing a second communication session for the emergency call with the first external electronic device using the short-range wireless communication module, and after receiving the location information from the second external electronic device, updating the first or second communication session by transmitting the received location information to the first external electronic device using the short-range wireless communication module.
