The present disclosure provides a transmission method for a common message and a device, which relates to a field of communication technologies and is invented for effectively ensuring that both a low cost MTC terminal and a normal LTE terminal may reliably receive the common message. The method for the common message includes: determining, by a network device, common message transmission time instances X corresponding to a terminal device, wherein the common message transmission time instances X are a part of cell common message transmission time instances; and transmitting, by the network device, a common message at the common message transmission time instances X corresponding to the terminal device. The present disclosure may be used in an M2M application based on an LTE network.
