The invention provided communication equipment, a communication method and a communication program which are capable of improving communication reliability. An application processing section 15 creates transmission request data which include data type information that indicates the transmission destination of transmission data to be transmitted and necessity of a response to the transmission data, a communication-medium processing section 16 stores communication-medium type information that indicates the type of the communication-medium, a communication mediation processing section 12 mediates the timing in transmitting the transmission data, based on the data type information which is included in the transmission request data that are created by the transmission-request data creating means and the communication-medium type information which is stored in the communication-medium processing section 16, and a data transmission processing section 14 transmits the transmission data according to the timing which is mediated by the communication mediation processing section 12.
