Base station, wireless terminal, communication system, communication method, and program

A communication system, wherein:

• a base station includes a wakeup signal transmission part transmitting transmission signal information to a wireless terminal by wireless communication, the transmission signal information including a wakeup signal starting a given function included by the wireless terminal;
• the wakeup signal transmission part transmits the transmission signal information including connection information in addition to the wakeup signal to the wireless terminal, the connection information being information for causing the wireless terminal of a destination of transmission of the wakeup signal to connect by wireless communication using the given function;
• and
• upon receiving the transmission signal information including the wakeup signal and the connection information, the wireless terminal starts the given function included by the wireless terminal in response to the wakeup signal and executes a connection process by the started given function using the connection information,
• wherein the wakeup signal transmission part regulates a frame length of a wireless frame so that the frame length includes the transmission signal information, and transmits the transmission signal information that includes the wakeup signal and the connection information and is expressed by the frame length of the wireless frame.
