Terminal triggering method and device

The invention discloses a terminal triggering method and a device. The method comprises the steps that a server determines to establish connection with terminals to be triggered, the server acquires a default group bearing identity of a terminal group to which the terminals belong from an MTC-IWF (Machine Type Communication-Interworking Function), the default group bearing identity is used for identifying EPS (Evolved Packet System) bearing unifiedly used by all the terminals in the terminal group to establish the connection with the server, the server transmits a triggering message carrying group identities or an identity set of the terminals and the default group bearing identity to a service P-GW (Packet Data Network Gateway) of the terminal group, and the triggering message is used for informing the service P-GW to trigger the terminals in the terminal group to establish the connection with the server with default group bearing. The method and the device can avoid network congestion due to the fact that the server is required to acquire IP (Internet Protocol) address information of the terminals one by one.
