1. A master node comprising:
- a scheduler configured to transmit, to a slave node, first resource reservation information, and to allocate a first radio resource corresponding to the first resource reservation information;
an exchanger configured to transmit first security information of the master node to the slave node and receive first security information of the slave node using the allocated first radio resource; and
a controller configured to determine whether the master node successfully receives the first security information of the slave node and the slave node successfully receives the first security information of the master node, and, based on the determination, generate second security information using the first security information of the slave node and the first security information of the master node,wherein the exchanger is further configured to transmit the generated second security information to the slave node and receive second security information of the slave node using second radio resource, andwherein the scheduler is further configured to transmit second resource reservation information to the slave node in response to the controller having determined that the master node does not successfully receive the first security information of the slave node or the slave node does not successfully receive the first security information of the master node, and to allocate a third radio resource corresponding to the second resource reservation information.

Abstract
An operation method of a master node, the method including transmitting, to a slave node, a first resource reservation information including packet information about a packet to be transferred between the master node and the slave node; allocating a radio resource corresponding to the first resource reservation information, for exchanging security information; transferring the packet using the allocated radio resource; and determining whether the packet was successfully transferred based on the packet information.

1. A master node comprising:
-
a scheduler configured to transmit, to a slave node, first resource reservation information, and to allocate a first radio resource corresponding to the first resource reservation information; an exchanger configured to transmit first security information of the master node to the slave node and receive first security information of the slave node using the allocated first radio resource; and a controller configured to determine whether the master node successfully receives the first security information of the slave node and the slave node successfully receives the first security information of the master node, and, based on the determination, generate second security information using the first security information of the slave node and the first security information of the master node, wherein the exchanger is further configured to transmit the generated second security information to the slave node and receive second security information of the slave node using second radio resource, and wherein the scheduler is further configured to transmit second resource reservation information to the slave node in response to the controller having determined that the master node does not successfully receive the first security information of the slave node or the slave node does not successfully receive the first security information of the master node, and to allocate a third radio resource corresponding to the second resource reservation information. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8)

9. A master node comprising:
-
a scheduler associated with a link layer; and a security manager configured to transfer first and second security information to the scheduler, wherein the security manager is further configured to request the scheduler to allocate a first radio resource for exchanging the first security information with the slave node and a second radio resource for exchanging the second security information with the slave node, and the link layer is configured to transmit the first security information to the slave node using the allocated first radio resource, and in response to the first security information being successfully exchanged, transmit the second security information to the slave node using the allocated second radio resource. - View Dependent Claims (10, 11, 12)

13. An operation method of a master node, the method comprising:
-
transmitting, to a slave node, first resource reservation information; allocating a first radio resource corresponding to the first resource reservation information; transmitting first security information of the master node to the slave node and receiving first security information of the slave node; determining whether the master node successfully receives the first security information of the slave node and the slave node successfully receives the first security information of the master node; based on the determination, generating second security information using the first security information of the slave node and the first security information of the master node; transmitting the generated second security information to the slave node and receive second security information of the slave node using second radio resource; and transmitting second resource reservation information to the slave node in response to having determined that the master node does not successfully receive the first security information of the slave node or the slave node does not successfully receive the first security information of the master nod, and allocating a third radio resource corresponding to the second resource reservation information. - View Dependent Claims (14, 15, 16, 17, 18)
