Abstract

A system and method for transmitting data packets to a wireless client is presented herein. The data packets are received by a wireless content switch in the wireless network. The wireless content switch assigns the priority of transmission for the data packet based on both the purchased level of service by the subscriber receiving the data packet, as well as the application the data packet is transmitted.

Claims

1. A method of transmitting data packets to a wireless client, said method comprising:

receiving a data packet for a particular wireless client; and

assigning a radio priority for the data packet based on two or more parameters.

2. The method of claim 1, further comprising:

transmitting the data packet with the radio priority of the data packet based on two or more parameters.

3. The method of claim 1, wherein receiving the data packet further comprises receiving a data packet with an original radio priority;

4. The method of claim 3, wherein receiving the data racket with an original radio priority further comprises:

receiving the data packet with an original radio priority based on a quality of service parameter.

5. The method of claim 1, wherein assigning a radio priority for the data packet based on two or more parameters further comprises:

assigning a radio priority for the data packet based on a quality of service parameter associated with the wireless client and a type of service parameter.

6. The method of claim 5, wherein assigning a radio priority for the data packet based on the quality of service parameter associated with the wireless client and type of service parameter further comprises:

determining the identity of the wireless client; and

retrieving the quality of service parameter associated with the wireless client.

7. The method of claim 5, wherein assigning a radio priority for the data packet based on the quality of service parameter associated with the wireless client and type of service parameter, further comprises

examining a transmission control protocol layer of the data packet.

8. The method of claim 1, wherein the two or more parameters are from two or more Open Systems International (OSI) layers.

9. A wireless content switch for transmitting data packets to a wireless client, said wireless content switch comprising:

an upstream port for receiving a data packet for a particular wireless client;

a bus coupled to the upstream port;

memory coupled to the bus, the memory for storing executable code and a radio priority table; and

a processor for executing the executable code, the code, when executed selecting a radio priority from the radio priority table for the data packet based or two or more parameters.

10. The wireless content switch of claim 9, further comprising:

a downstream port coupled to the bus, the downstream port for transmitting the data packet with the radio priority for the data packet based on two or more parameters.

11. The wireless content switch of claim 9, wherein the upstream port receives the data packet with an original radio priority.

12. The wireless content switch of claim 9, wherein the upstream port receives the data packet with an original radio priority based on a quality of service parameter.

13. The wireless content switch of claim 9, wherein the executable code, when executed, assigning the radio priority for the data packet based on a quality of service parameter associated with the-wireless client and a type of service parameter.

14. The wireless content switch of claim 13, wherein the memory stores a plurality of records, each of said plurality of records associated with a wireless client, each of said plurality of records comprising:

a wireless client internet protocol (IP) address identifier for identifying an IP address for the wireless client associated with the record; and

a wireless client quality of service identifier for identifying the quality of service for the wireless client associated with the record.

15. The wireless content switch of claim 13, wherein the executable code, when executed determining the type of service parameter by examining a transmission control protocol layer of the data packet.
