Disclosed are a service message transmission method, device and system, for reducing a communication overhead between an M2M server and an MQTT server. The method comprises: when the M2M server needs to transmit first service messages having the same content to at least two M2M terminals corresponding to a first resource stored in the M2M server, the M2M server determines a first common subject generated for the first resource and transmits once a first MQTT message to the MQTT server; the first MQTT message comprises the first service message and the first common subject, the first service message comprising therein the same content to be transmitted to the at least two terminals. The method is applied to an M2M system.
