<p>PURPOSE: To provide a communication system whose reliability is high and which can efficiently execute communication by adding information of an identification mode and the like to data and transmitting it in a radio communication system whose direct propriety of data transmission is easy to change. CONSTITUTION: The radio module parts 3 of respective radio communication units transmit a packet having data, the transmission source/transmission destination identification codes of data and the transmission source/transmission destination identification codes of the packet to the radio module parts 3 of the other units. Data which an application part 2 transmits is generated and received data is processed. Then, the service of a radio network is supplied to a user. A processing for adding the identification code to data is executed in a communication processing part 1. A packet transmission part 11 reads out the information of the identification code stored in the memory 18 of another machine information management part 13, adds transmission data to it, generates the packet and gives it to a radio transmission part 14, for example. The radio transmission part 14 converts the packet into a signal string and gives it to the radio module part 3.</p> |
