Abstract: The present disclosure discloses a method and device for receiving and sending a message, a channel unit and communication equipment. The method for receiving and sending the message of the present disclosure specifically includes that: a channel unit receives a message sent by equipment born by an equipment network interface; the channel unit judges whether the received message is a message required to be processed by a CPU or not; when a judgment result is that the received message is the message required to be processed by the CPU, the channel unit sends the message to the CPU, receives a response message returned by the CPU, and directly forwards the response message to the equipment; and when the judgment result is that the received message is not the message required to be processed by the CPU, the channel unit generates and sends a corresponding response message to the equipment.
