9. A packet control function, comprising:
-
a packet data control section for monitoring whether there is data to be transmitted to/from a terminal or to/from a packet data serving node and generating messages for keep-alive of a session between a terminal and a network according to the monitoring result; and
a session management section for releasing and/or connecting the session based on the messages.

10. A method of keeping-alive a session between a terminal and a network in a communication device having a packet data control section and a session management function, comprising:
-
monitoring whether there is data to be transmitted to/from the terminal or to/from a packet data serving node where the terminal is in an idle mode or dormant mode;
where there is no data, transmitting a message for confirming that a predetermined session is effective or not to the terminal; and
where there is no response to the message, terminating the predetermined session.

11. A method of keeping-alive a session between a terminal and a network in a communication device having a packet control function and a session management function, comprising:
-
storing registration information related to newly established session;
generating a message for stopping a timer for keep-alive of the established session; and
stopping the timer based on the message.

12. A method of keeping-alive a session between a terminal and a network in a communication device having a packet control function and a session management function, comprising:
-
generating a first message for driving a timer for keep-alive of a predetermined session when a connection between the terminal, the network, and the communication device is released by a request of the terminal;
driving the timer based on the first message and monitoring whether there is data to be transmitted to/from the terminal or to/from a packet data serving node; and
adjusting the keep-alive of the predetermined session according to the monitoring result. - View Dependent Claims (13, 14)

15. A method of keeping-alive a session between a terminal and a network in a communication device having a packet control function and a session management function, comprising:
-
establishing a connection between the terminal, the network, and the communication device by request of a packet data serving node;
generating a message for stopping a timer for keep-alive of a predetermined session after the establishing step; and
stopping the timer based on the message. - View Dependent Claims (16)

17. A session keep-alive control method in a mobile communication network, having a Access Terminal, an access network, a packet control function (PCF), and a packet data serving node (PDSN), for supporting a packet data service, the method comprising the steps of:
establishing a session between the AT and the access network, and registering information of the established session in the PCF;
starting driving of a timer for a keep-alive function at the PCF;
after a connection between the mobile station and the access network is established, transmitting a connection setup request message for the mobile station to the PCF at the access network;
transmitting a connection setup completion message for informing completion of the requested connection setup to the access network at the PCF;
stopping the driving of the timer for the keep-alive function at the PCF; and
transmitting/receiving desired packet data through a connection path set between the mobile station and the PDSN. - View Dependent Claims (18, 19)
