Abstract
Official abstract text for this publication.
A method and apparatus for reconfiguring device-to-device (D2D) connection information in a wireless communication system is provided. A first device is connected to a second device through a D2D connection. The first device receives a connection reconfiguration request message including at least one of a new quality of service (QoS) parameter, a new security information parameter, and a new D2D identifier, transmits a connection reconfiguration response message, which indicates whether to accept the request of the connection reconfiguration, to the response of the connection reconfiguration request message, and receives a connection reconfiguration confirm message.
First claim
Opening claim text (preview).
What is claimed is: 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. 2. The method of claim 1 , wherein the new D2D identifier is a link level D2D identifier allocated to a physical link between the first UE and the second UE. 3. The method of claim 1 , wherein the new D2D identifier is a connection/flow level D2D identifier allocated to a logical link between the first UE and the second UE. 4. A first user equipment (UE) which is connected to a second UE through a pre-established D2D connection, the first UE comprising: a radio frequency (RF) unit that transmits or receives a radio signal; and a processor, operatively coupled to the RF unit, and configured to: receive, 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; transmit, 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; receive, 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 apply 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. 5. The first UE of claim 4 , wherein the new D2D identifier is a link level D2D identifier allocated to a physical link between the first UE and the second UE. 6. The first UE of claim 4 , wherein the new D2D identifier is a connection/flow level D2D identifier allocated to a logical link between the first UE and the second UE.
