Method for processing exceptional case of establishing default bearer in mobile communication system and device therefor

Abstract

There are provided a method for processing an exceptional case of establishing a default bearer and a device therefor in order to solve a problem in that a user equipment cannot actually receive an IP service by accessing a packet network while failing in establishing the default bearer in a mobile communication system. A method for processing an exceptional ease of establishing a default hearer in a mobility management entity includes: receiving a network attachment request from a user equipment; transmitting a network attachment acceptance including an activation request of the default bearer to the user equipment in response to the network attachment request; and cancelling a network attachment procedure when a completion response to the activation request of the default bearer is not received from the user equipment within a predetermined time.

         2 . A method for performing a network attachment procedure in a network, comprising:
 receiving a request message from a user equipment, the request message including a request to attach the user equipment to the network;   transmitting an acceptance message including a request for activation of a default bearer by the user equipment; and   aborting the network attachment procedure if an acknowledgement of the activation of the default bearer is not received from the user equipment within a predetermined time.
