摘要：
A communication apparatus which starts communication using a power-saving function changes, with its communication counterpart, a key for a confidential mode and performs power-saving communication. When terminating the power-saving function, the communication apparatus returns, with its communication counterpart, the key for the confidential mode to the original one. Then, after returning the key for the confidential mode to the original one, the communication apparatus performs an IP address reassignment process.
