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 case of establishing a default bearer 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.

Abstract: A method and apparatus for handover based on cooperation between base stations are provided. When a message indicating handover completion is received from a terminal that has determined whether to perform handover and that has performed handover to a target base station, the target base station transmits a message requesting information on the terminal to a serving base station of the terminal. Then, the target base station receives information on the terminal from the serving base station and transmits data to the terminal.

Abstract: A method and apparatus for handover is provided. In a network environment in which a plurality of beams are provided within a base station, a terminal measures signal strength of a serving beam and signal strength of a target beam and transmits a measurement report message when a first condition or a second condition is satisfied. The base station determines inter-beam coordinated scheduling when the signal strength of the serving beam and target beam satisfy the first condition, and determines handover between beams when the signal strength of the serving beam and target beam satisfy the second condition. The base station transmits a message for commanding handover to the terminal when the handover between beams is determined. The terminal then stops communicating with the serving beam and performs handover to the target beam.

Abstract: A D2D (Device-to-Device) communication method is provided which enables a first terminal of a first group to directly communicate with other terminals of the first group without relay of a base station. The first terminal receives first data from a second terminal. The first terminal determines whether the first data is destined for the first group by using a group identifier of the first data. When the first data is destined for the first group, the first terminal identifies at least one first RLC entity, among multiple RLC (Radio Link Control) entities, that corresponds to the second terminal by using the source terminal identifier of the first data.
