The utility model provides an emergent communication system, including mobile terminal and with mobile terminal wireless connection's management terminal, mobile terminal and management terminal have a plurality ofly, and every management terminal has bound at least one mobile terminal, mutual wired connection arrives together between the management terminal. Among this technical scheme, being in the same place through wired connection between the management terminal, through wired communication mode, having avoided the high -power signal transmission of signal tower in the cell -phone communication, mobile terminal is then adopt the miniwatt antenna, realize with management terminal 100 rice in the emergency communication, signal interference is less in in 100 -meter dash, avoids signal interference to external world when guaranteeing the communication quality.
