Abstract
A receiving unit receives a handover request from a terminal apparatus. As the handover request is received, a requesting unit requests a control apparatus connected via a network that an encryption key used for wireless communication performed between the terminal apparatus and a handover source base station apparatus be outputted. As the encryption key is received from the control apparatus as a response to the request, a tentative execution unit performs wireless communication with the terminal using the encryption key using the encryption key. While wireless communication is being performed between the tentative execution unit and the terminal, a setting unit determines a new encryption key between the setting unit and the terminal and continues to perform wireless communication after updating the encryption key with the new encryption key.
