Apparatus and method for dividedly transmitting and receiving message data using connection codes appended as part of the transmission packets data field

摘要

When one message data is transmitted dividedly at plural times to the same reception terminal, in the first transmission, a code specifying the terminal is transmitted, and then message data in a head portion of the message and a code indicating that succeeding data is present are transmitted, in the second transmission and thereafter, the code specifying the terminal is transmitted, and then data succeeding to the transmitted message data and a code indicating that the previously transmitted message data is continued from message data received at this time, and, unless the second transmission and thereafter is the last transmission, the message data having a code indicating that succeeding data is present are transmitted. The reception terminal receives transmitted data, and connects message data transmitted dividedly at plural times as one message data based on the code attached to the received message data.
