Claim:
1. A method for reconfiguring, by a first user equipment (UE), device-to-device (D2D) connection information in a wireless communication system, the first UE being connected to a second UE through a pre-established D2D connection, the method comprising: receiving, from the second UE, a connection reconfiguration request message including a new quality of service (QoS) parameter, a new security information parameter, and a new D2D identifier; transmitting, to the second UE, a connection reconfiguration response message, which indicates whether to accept a request of a D2D connection reconfiguration, in response to the connection reconfiguration request message; receiving, from the second UE, a connection reconfiguration confirm message which indicates a success of the D2D connection reconfiguration when the first UE accepts the request of the D2D connection reconfiguration; and applying the new QoS parameter, the new security information parameter, and the new D2D identifier to the pre-established D2D connection so as not to establish a new D2D connection.
