AI Technical Summary

Technical Problem

In existing technologies, when the terminal device has insufficient power or is damaged, it cannot reliably make emergency calls, which prevents the rescue platform from obtaining accurate location information and affects emergency rescue.

Method used

By using short-range communication between the first and second devices, relevant information from the second device is obtained and sent to the third device to ensure reliable transmission of emergency information. The third device then parses this information and sends a paging message to the first device to ensure the delivery of rescue information.

Benefits of technology

When the second device has insufficient power or is malfunctioning, the method of joint calling by multiple devices ensures the reliable transmission of emergency information and improves rescue efficiency.

Abstract

This application provides a multi-device joint calling method and apparatus. The method includes: a first device establishing short-range communication with a second device; the first device obtaining relevant information about the second device based on the short-range communication; the first device sending the relevant information of the second device and the relevant information of the first device to a third device; and the first device receiving a paging from the third device. The paging is sent by the third device based on the relevant information of the second device and the relevant information of the first device. In this way, in cases where the second device has insufficient power or malfunctions, the second device can reliably transmit emergency information through the first device. This allows the third device to analyze the relevant information of the second device and the relevant information of the first device, send a paging to the first device, and obtain rescue-related information, thereby dispatching personnel to carry out rescue operations.
