Cloud Token Emergency Location Service
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In developing countries, emergency call centers often lack the infrastructure to reliably determine the location of callers using wireless devices, which can hinder timely and accurate emergency responses.
Innovation Solution
A method where a wireless UE device uses cloud service technology to provide location information to an emergency call center by generating and transmitting a token associated with the device's location, allowing the call center to retrieve this information securely and accurately, even in areas with limited infrastructure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cloud-based token system is implemented, then location information transmission reliability is improved, but device complexity increases
Solution Approach 1:
A cloud-based location server acts as an intermediary between the mobile device and emergency call center. The server stores location information and manages token generation, mediating the information exchange without requiring complex local processing on the device. The device only needs to request tokens and transmit them during emergency calls, significantly reducing device complexity while maintaining high reliability through centralized server management.
2Reliability
If token-based security mechanism is used, then security against spoofing is improved, but communication overhead increases
Solution Approach 1:
Location information is obtained and stored on the cloud server in advance, before the emergency call is made. When an emergency call occurs, only a compact token (not the entire location dataset) needs to be transmitted during the call. This preliminary action reduces the amount of data that must be communicated during critical emergency situations, minimizing communication overhead while maintaining strong security through token verification.
3Ease of operation
If location information is stored on cloud server, then accessibility to location data is improved, but data security risks increase
Solution Approach 1:
The system implements differentiated access control where the cloud server stores location data with varying levels of accessibility. Location information is stored centrally for easy retrieval, but access is restricted through token-based authentication that grants permissions only to authorized entities (emergency call centers) under specific conditions (during emergency calls). This local quality approach allows simultaneous achievement of high accessibility for authorized users and enhanced security through access restrictions.

AI summary
A method for a wireless UE device to utilize tokens and cloud service technology to facilitate the provision of location data to an emergency call center. The UE may provide cellular signaling to initiate an outgoing telephone call to an emergency call center. A token may be provided during the signaling, wherein the token is associated with location information of the UE device stored on a server computer (referred to as a cloud server or location server). The token may uniquely identify the UE device and/or a user cloud service account of the UE device. The call center may use the token to retrieve location information of the UE from the cloud server. The use of the token may also provide for enhanced security, e.g., to prevent spoofing of the UE phone number.
