Method and apparatus for managing a pdn connection in a wireless communication system

A node for managing a packet data network (PDN) connection in a wireless communication system, the node comprising:

• a transceiver configured to transmit and receive information on a PDN connection management to and from a terminal;
• a controller operably connected to the transceiver, the controller configured to:
• detect a terminal in which a failure occurs in the PDN connection by the node;
• and
• transmit a detach request message to a terminal in which a failure occurs;
• and
• a storage operably connected to the controller, the storage configured to store information on the terminal in which the failure occurs and a retry count of trying reattach by the terminal in the node.

A method for managing a packet data network (PDN) connection of a terminal in a wireless communication system, the method comprising:

• receiving, by the terminal in which a failure occurs in a PDN connection between the terminal and a PDN, a detach request message from a node;
• performing, by the terminal, detach;
• and
• attaching the terminal.
