Abstract

An apparatus and method for QoS management including a wireless network having a plurality of base stations capable of communicating with a plurality of mobile stations in a coverage area of the wireless network, and having a packet classification element, configured to classify packets to be delivered to a mobile station; an information processing element, configured to process the packets from the packet classification element; and an information scheduler element, configured to coordinate delivery of the packets to the mobile station.

Claims

1. A wireless network having a plurality of base stations capable of communicating with a plurality of mobile stations in a coverage area of the wireless network, comprising:

a packet classification element, configured to classify packets to be delivered to a mobile station;

an information processing element, configured to process the packets from the packet classification element; and

an information scheduler element, configured to coordinate delivery of the packets to the mobile station.

2. The wireless network as set forth in claim 1, wherein the packet classification element classifies packets into different traffic classes.

3. The wireless network as set forth in claim 1, wherein the packet classification element classifies packets into classes including constant bit rate, variable bit rate, and unspecified bit rate.

4. The wireless network as set forth in claim 1, wherein the packet classification element classifies packets into classes on the basis of the one or more of source IP address, destination IP address, and port numbers.

5. The wireless network as set forth in claim 1, wherein the packets to be classified by the packet classification element are managed using a diffserv protocol.

6. The wireless network as set forth in claim 1, wherein the information scheduler element prioritizes the packet flow of the packets.

7. The wireless network as set forth in claim 1, wherein the information scheduler element prioritizes the packet flow of the packets according to delay, jitter, and type of traffic requirements.

8. The wireless network as set forth in claim 1, wherein the information scheduler element schedules delivery of the packets to the destination mobile station by specifying data links and flows.

9. The wireless network as set forth in claim 1, wherein the information scheduler element schedules delivery of the packets to the destination mobile station using an Intserv protocol.
