PURPOSE: To reduce a data transmission time and to attain efficient use of a radio line even if many data to be sent are required by providing a means setting plural call numbers to a mobile radio terminal set.
CONSTITUTION: In case of multiple address communication, a multiple address call number for receiving a multiple address data is preset to each terminal set and a multiple address data is sent based on the number. That is, plural call numbers are set to a mobile radio terminal set. Then in case of the transmission of multiple address data, a multiple address call number is set in advance to the mobile radio terminal set. Then the multiple address data is sent only once based on the set multiple address call number. Thus, the signal for each terminal set has only to be only a multiple address call number in sending the multiple address data and the multiple address data is set only once. Since the multiple address call number is 10 characters or below and the multiple address data is several tens of characters, a large quantity of transmission data and the reduction in the transmission time are expected.
