  Abstract

As the scale, frequency, and duration of disasters increase worldwide, the damage caused by this is also increasing. It is important to know accurate information in responding to these disasters. CBS (Cell Broadcast Service) is one of the means to deliver disaster information easily and quickly. However, there are classes such as foreigners and children who do not understand the language supported by CBS. The requirements for CBS including language-independent content have been raised to narrow the information gap of these classes. Therefore, in this paper, we propose implementation methods to provide CBS including warning images to solve this problem. The proposed methods are to display warning symbols based on warning symbol identifiers or warning identification fields and to utilize Unicode emojis at user equipment. For each method, the process of displaying the warning image and the warning image information defined in this paper are presented. In addition, the requirements for the implementation of the proposed three CBS methods are presented.
