The embodiment of the invention discloses a machine type communication (MTC) system and method and device for off-line notification system, relates to the field of wireless communication, the type of machine used to solve the MTC system communication server (MTC server) or machine type communication users (MTC user) how to promptly informed the machine type communication device (MD). The problem of link status. In the invention, a mobility management entity (MME) or Serving GPRS support node (SGSN) detection in the link idle MD is reachable; in the link is detected the MD link is not reachable, notify MTC server and / or MTC user of the MD is not up to. By adopting the invention, MTC server and / or MTC user can learn the link state of MD in a timely manner.
