A large number of public security services such as anti-terrorism, social stability maintenance, social security demand for high sensitivity and confidentiality. Therefore, it is imperative to popularize BDS in the field of public security. A BDS-based public security information system  has realized the dynamic dispatch and integrated command of police resources, which has improved the response time and the execution efficiency.

The sector mainly includes the command and dispatch of public security vehicles, the on-site law enforcement management, emergency incident information transmission, public security time service, and other applications. Among them, the emergency incident information transmissions can be implemented by using the unique BDS short message function.
