Embodiments of the present invention disclose a method and a core network device for transmitting a device trigger message, and relate to the field of electronics and information technologies. By comparing validity time of a trigger message with duration of a timer, the present invention can prevent an invalid trigger message from being transmitted to a network, so as to reduce network load. The method according to the present invention includes: receiving a device trigger message sent by a first device, where the device trigger message includes information that indicates validity time of the device trigger message; when it is determined that a timer exists, comparing the validity time with duration of the timer; if the validity time is greater than the duration of the timer, sending the device trigger message to a user equipment UE after the timer times out; and if the validity time is not greater than the duration of the timer, sending a message to the first device and/or discarding the device trigger message, where the message is used to indicate that triggering is rejected, or transmission fails, or device triggering fails. |
