Apparatus and method for managing a session established using a wireless channel between a base station and a mobile device

A base station for managing a session established using a wireless channel between the base station and a mobile device in a mobile communication system, a first session maintenance signal being exchanged between a server coupled to the base station and an application processing unit inside the mobile device to confirm that a session is established between the server and the application processing unit, the base station comprising:

• a wireless interface unit to wirelessly communicate with the mobile device via the wireless channel;
• and
• a session management signal generating unit configured to send, to the server, one of control signals according to a connection state of the wireless channel, without sending the received first session maintenance signal to the mobile device via the wireless channel, the control signals including a second session maintenance signal responsive to the first session maintenance signal, a session disconnected signal indicating disconnection of the session, and a session established signal indicating restoration of the session.
