Access network device for managing queue corresponding to real time multimedia traffic characteristics and method thereof
First Claim
1. A queue management method of an access network device storing a received packet in a transmission queue and transmitting the stored packet to a destination node in a storage order, the method comprising:
- determining whether the packet is transmittable within a delivery deadline allowed for real-time traffic to the destination node; and
dropping the packet instead of storing the packet in the transmission queue when determined that the packet is not transmittable within the delivery deadline.

Abstract
A queue management method of an access network device includes receiving a packet, determining feasibility of a packet transmission within a delivery deadline allowed from a destination if the received packet is for real-time transmission, storing the packet in the transmission queue and transmitting the packet in sequential order of the storage when the packet transmission within the delivery deadline is feasible, and dropping the packet instead of storing the packet in the transmission queue when the packet transmission is determined infeasible. Accordingly, resources required for the packet transmission are saved.

6. A queue management method of an access network device providing a mobile node with access to a network and, in which if a packet destined for the mobile node is received, the access network stores the packet in a transmission queue and transmitting the stored packet to the mobile node in a storage order, the method comprising:
-
the access network device receiving from the mobile node a handover initiation packet indicating a beginning of a handover when the handover of the mobile node initiates;
the access network device transmitting the packet to a new access network device when the packet destined for the mobile node is received after the reception of the handover initiation packet;
determining whether the packet is transmittable within a delivery deadline allowed for real-time transmission at the mobile node when the packet is for real-time transmission; and
dropping the packet instead of storing the packet in the transmission queue when determined that the packet transmission is infeasible within the delivery deadline. - View Dependent Claims (7, 8, 9, 10, 11)

12. An access network device comprising:
-
a packet input part receiving a packet destined for a certain node;
a transmission queue storing the packet received through the packet input part and transmitting the packet in a sequential order of the storage; and
a controller dropping the packet instead of storing the packet in the transmission queue when the received packet is for real-time transmission and a prediction of infeasibility to transmit the packet within a delivery deadline allowed for the real-time transmission packet to a destination node has been made. - View Dependent Claims (13, 14, 15, 16)

17. An access network device providing a mobile node with access to a certain network, the device comprising:
-
a packet input part receiving a packet destined for the mobile node and a handover initiation packet indicating a handover initiation of the mobile node;
a transmission queue storing the packet received after the reception of the handover initiation packet and transmitting the packet to a new access network device handover from the mobile node in a storage order; and
a controller dropping the packet instead of storing the packet in the transmission queue when the received packet is for real-time transmission and a prediction of infeasibility to transmit the packet within a delivery deadline allowed for the real-time transmission of the packet from a destination node has been made. - View Dependent Claims (18, 19, 20)

21. An access network device comprising:
-
a packet input part receiving and/or transmitting packets to and/or from a node; and
a transmission queue storing the packets in a sequential order and dropping the packets after transmitting the packets to the node when the received packets are for real-time transmission and when predicted that the packets are not transmittable to the node within a predetermined time. - View Dependent Claims (22, 23, 24, 25, 26)
