LG Uplus has demonstrated technology that narrows the search area for mountain rescue operations by utilizing mobile communication base station data and mobile phone connection records.
On October 11, LG Uplus announced that it conducted this demonstration in the Unjang Mountain area of Jinan, North Jeolla Province, in collaboration with Solbit Systems, a company specializing in radio wave analysis.
The demonstration was based on scenarios where GPS signals are unavailable in mountainous areas or when mobile phones are turned off, making it difficult to pinpoint exact locations.
Solbit Systems, which specializes in radio wave analysis and simulation technology for defense applications, is expanding its research to apply related technologies to civilian disaster and rescue operations.
In situations where GPS-based location verification is challenging, rescue teams previously had to search a wide area based on the last base station connected to the lost person's mobile phone.
During this trial, the Intelligent Search Assistance System (iSAR) developed by Solbit Systems was utilized. This system allows for the identification of the last connected base station and analyzes connection records over time and the radio wave reach based on terrain to estimate areas where the lost person is likely to be found.
The results showed that the estimated search area using the previous method, which centered on the last connected base station with a 15 km radius, was 706.86 square kilometers. By analyzing the base station location, antenna direction, and radio wave reach, this was reduced to 45.94 square kilometers, and further analysis of time-based mobile phone connection records brought it down to 4.13 square kilometers. This represents a reduction of about 99% compared to the previous method.
If this technology is applied in actual rescue situations, it is expected to help quickly narrow down the areas that rescue teams need to search. This is particularly significant as it allows for the use of communication data in situations where GPS cannot provide accurate location information. Through this demonstration, LG Uplus has confirmed the potential to utilize communication network information for customer safety and emergency rescue support.
In the future, LG Uplus and Solbit Systems plan to conduct additional tests to verify the accuracy and applicability of the technology and explore ways to integrate it into the search support systems of emergency rescue agencies.
Lee Sang-heon, head of network pre-development at LG Uplus, stated, "This demonstration is a meaningful case confirming that communication data can be used to protect customers' lives and safety in situations of distress or disappearance. We will continue to validate the technology to ensure that customers can receive faster rescue support in emergencies and develop measures to enhance customer safety and peace of mind."
