A microwave access global intercommunication system and a method and device for providing a emergency service are disclosed to cause the microwave access global intercommunication system can provide the emergency call service, including: when a network side (20) receives an access-to-network request from a terminal (10), if the network side (20) can't authenticate the terminal (10) or don't authenticate via negotiation during the request, the network side (20) establishes a service flow of loading the emergency service for the terminal (10) and assigns an IP address to the terminal (10), the terminal (10) acquires the IP address assigned by the network side (20) and uses the assigned IP address to perform the emergency service through the service flow established. The terminal (10) may acquire the IP address assigned by the network side (20) during the service flow establishment and also may acquire the IP address assigned by the network side (20) through the DHCP manner.
