METHOD FOR ESTABLISHING A CONNECTION BETWEEN A NODE OF A COMMUNICATION SYSTEM AND A NODE OF A DATA SERVICE NETWORK IN A WIRELESS COMMUNICATION SYSTEM

摘要

The present invention relates to a method for establishing a connection between a node of a communication system and a node of a data service network in a wireless communication system. A method in which a mobility management entity establishes a connection with a node of a network according to one embodiment of the present invention comprises a step in which the mobility management entity acquires an address identification address; a step in which the mobility management entity transmits a create session request to a serving gateway; a step in which the mobility management entity receives a create session response corresponding to the create session request from the serving gateway; a step in which the mobility management entity transmits, to the serving gateway, downlink bearer information for receiving data from the serving gateway; and a step in which the mobility management entity communicates with a node by using a mobility management entity identification address and the node identification address in accordance with uplink bearer information and downlink bearer information. According to one embodiment of the present invention, a connection between a node of a user data network and a node of a communication system can be established in an efficient manner.
