Disasters are increasing rapidly due to the increase of population, gigantism of cities, advancement of traffics, and abnormal weather phenomena, and the scale of damages is also getting wider. Natural disasters and artificial disasters are almost unavoidable, but in the case of artificial disasters, we can decrease damage levels using constantly developing IT technology, such as sensing and monitoring technology which can be used for preventing and mitigating disasters. Emergency Preparedness Telecommunications Systems, the system make a gradual complication according to development of information communication technology. An emergency telecommunication function was the focus of communication service for an emergency communication and restoration at the disaster occurrence area at the beginning, but the communication function of disaster prevention area is imported. In this paper, we study on development technology, construction plan of next-generation disaster wireless communication and proposed the systems.

South Korea decided to use the public safety long term evolution (PS-LTE) method to build a wireless communications network for national disaster. The move will allow all disaster management agencies, including police, firefighters and the military to use multimedia information, including videos, in addition to voice to carry out rescue operations from 2017. The Ministry of Science, ICT and Future Planning said Thursday that it adopted PS-LTE as the technology method for national disaster management system following a national policy coordination meeting last month. PS-LTE is a method integrating group communication, direction communication between terminals and independent base station function with existing LTE technology. Until now, disaster management agencies used technology that only allowed voice communication. However, transmission of multimedia information is possible using PS-LTE.
