To solve the problem that, under the environment where it takes too much time for disconnecting a packet, such as under an environment of an adverse radio status, in a case where there is a notification of voice call or mail arrival during multi-packet communication, it becomes impossible to respond to the incoming call.

There is provided a reconnection control unit 3-3 in which, if there is a notification of voice call or mail arrival from a base station with respect to a communication terminal during multi-packet communication using all slots between the base station and the communication terminal, in a case where it is impossible to respond to the incoming call even by disconnecting the slot being used, reconnection control is performed to continue packet communication by making at least one slot free.
