The embodiment of the present invention provides a message transmission method, device and system, which relates to the field of communication technology. Without the need for user equipment to carry the information of the forwarding device in the published message, the message can be successfully transmitted to the corresponding forwarding device, thereby improving the utilization rate of the empty port resources in the packet service. This includes: the access network node receives the upstream message sent by the user equipment, which includes the first index information, in which the first index information is used to find the first forwarding device for forwarding the upstream message; furthermore, the access network node can determine the first forwarding device corresponding to the first index information and send the upstream message to the first forwarding device.
