Emergency SMS Location Precalculation in User Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to accurately determine the location of user equipment (UE) prior to sending an SMS message to emergency services, leading to potential delays or incorrect routing of emergency texts.
Innovation Solution
The UE transitions into an emergency mode upon identifying the recipient as an emergency number, enabling location services and initiating a location calculation before the SMS is composed, ensuring the location is determined by the time the user sends the message.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the location calculation is initiated after the SMS message is composed, then the system complexity is reduced, but the location determination time increases causing delays in emergency response
Solution Approach 1:
The patent applies preliminary action by initiating the location calculation process as soon as the emergency number is detected as the recipient, which is before the SMS message composition is completed. This allows the location to be determined by the time the user sends the message, eliminating delays in emergency response while maintaining manageable system complexity through phased activation of location services.
2Measurement precision
If location services are enabled earlier, then the location accuracy is improved, but the energy consumption increases
Solution Approach 1:
The patent enables location services in advance upon detecting the emergency number, improving location accuracy before the message is sent. However, it applies energy conservation by selectively activating location services only when an emergency number is detected, rather than continuously, thus balancing accuracy improvement with energy consumption management.
Solution Approach 2:
The patent changes the operational state of location services from inactive to active based on the parameter change of detecting an emergency number as the recipient. This conditional activation allows the system to achieve high location accuracy when needed while minimizing energy consumption during normal operations.
3Loss of time
If the location is calculated before sending the SMS, then the emergency response time is reduced, but the device processing load increases
Solution Approach 1:
The patent performs location calculation in advance upon detecting the emergency number, reducing emergency response time. The processing load is managed by activating location services only when necessary (when an emergency number is detected) rather than continuously, and by using efficient location determination methods that balance accuracy with processing requirements.

AI summary
Systems, methods, and computer-readable media are provided for calculating a location of user equipment (UE) prior to communicating an SMS message to an emergency number. More particularly, additional time is provided to location services so a complete location can be determined, prior to an SMS message being composed and communicated to emergency services. To do so, the UE transitions into an emergency mode as soon as the recipient of the text message is identified as an emergency number (e.g., 911). This immediately causes the UE to unblock all numbers (i.e., in case emergency services needs to initiate a voice call to the UE), enable location services, and initiate a location calculation. As a result, the location calculation is already determined by the time the user composes the text hits send.
