Method for managing binding and tunnel information in communication system and apparatuses for the same

An embodiment of the present invention discloses a method for managing binding and tunnel information in a communication system supporting handover between heterogeneous communication networks based on a mobile internet protocol (IP). The method is executed by a terminal. The method comprises a step of determining whether a packet is received from a server through a first communication network during a predetermined time; a step of determining the effectiveness of the binding and tunnel information for the first communication network when the packet is not received during the predetermined time; and a step of processing the binding and tunnel information for the first communication network according to the determination result of the effectiveness.
