PURPOSE:To decrease the data transmission total required time and to reduce the cost required for data transmission by sending the presence of an error in transmission of a talking route selection data to a base station. CONSTITUTION:An adaptor 10F uses an antenna 12 and a reception section 13 to receive a talking route selection data, which is stored in a memory 14. A transmission data from a public network b21 includes designation information representing it that its content is the talking route selection data and the reception section 13 identifies the data. Then the talking route selection data is sent from a base station of the public network b21 repetitively for plural number of times, stored in the memory 14 and a deciding section 15 uses majority decision logic to decide a correct data, which is stored in a memory 17. The deciding section 15 outputs a data representing the presence of an error in the reception data to an error signal transmission section 18. Thus, the time required for data transmission is decreased and the cost is reduced. |
