To improve efficiency of a radio section while reducing a no-communication period in the case of handoff in communication used DRC and DSC signals. A communication connection apparatus (BS)provided in a communication system accumulates data transmitted from the communication control apparatus (BSC). In a state in which a DSC signal from a communication terminal (AT)designates an owed BS, when a DRC indication from the ATis switched from another BS to the owned BS, the BStransmits data received from the BSClast to the ATout of the data accumulated in the BS. Consequently, missing data is requested from the BSat a handoff destination in accordance with a retransmission request function existing in the AT. Moreover, retransmission processing for data by a retransmission request message is performed in the BS
