Abstract

A method of renegotiating QoS levels of a communication link in one or more networks, the communication link having an initial QoS level prior to renegotiation, includes examining information flowing on the communication link between a first network endpoint and a second network endpoint. The method also includes determining, based on the information, a type of application being used by the first and second network endpoints for the communication link. The method further includes determining a QoS level that is suitable for the application, and negotiating with at least one of the one or more networks to procure resources associated with the network that will provide the suitable QoS level.

Claims

1. A method of providing a QoS level in a network, comprising:

examining communications flowing between a first network endpoint and a second network endpoint;

determining, based on the communications, an application being used by the first and second network endpoints for the communications;

determining a QoS level that is suitable for the application; and

, requesting resources associated with the network that will provide the suitable QoS level for the communication.

2. The method of claim 1, wherein examining communications further includes analyzing packets flowing between the first and second network endpoints at a transport layer level.

3. The method of claim 1, wherein examining communications further includes analyzing packets flowing between the first and second network endpoints at an application layer level.

4. The method of claim 1, wherein the suitable QoS level is a higher level of QoS as compared to a QoS level prior to requesting the resources.

5. The method of claim 1, wherein the suitable QoS level is a lower level of QoS as compared to a QoS level prior to requesting the resources.

6. The method of claim 5, further including a dampening timer, wherein requesting the resources does not occur until the dampening timer expires.

7. The method of claim 1, wherein determining the suitable QoS level further includes examining a profile of at least one subscriber associated with the network endpoints, and linking the suitable QoS to the profile.

8. The method of claim 1, further including modifying billing records to reflect a change in QoS levels.

9. A method of renegotiating QoS levels of a communication link in one or more networks, the communication link having an initial QoS level prior to renegotiation, comprising:

examining information flowing on the communication link between a first network endpoint and a second network endpoint;

determining, based on the information, a type of application being used by the first and second network endpoints for the communication link;

determining a QoS level that is suitable for the application; and

, negotiating with at least one of the one or more networks to procure resources associated with the network that will provide the suitable QoS level.

10. The method of claim 9, wherein determining the suitable QoS level further includes examining a profile of at least one subscriber associated with the network endpoints, and linking the suitable QoS to the profile.

11. The method of claim 9, further including modifying billing records to reflect a change in QoS levels.

12. The method of claim 9, wherein examining information further includes analyzing packets flowing between the first and second network endpoints at a transport layer level.

13. The method of claim 9, wherein examining information further includes analyzing packets flowing between the first and second network endpoints at an application layer level.

14. A system for negotiating QoS levels of a communication link in one or more networks, the communication link having an initial QoS level prior to the negotiation, comprising:

a traffic analyzer for examining information flowing on the communication link between a first network endpoint and a second network endpoint, and determining, based on the information, a type of application being used by the first and second network endpoints for the communication link determining a QoS level that is suitable for the application; and

,

a network negotiating component for negotiating with at least one of the one or more networks to procure resources associated with the network that will provide the suitable QoS level.

15. The system of claim 14, wherein the traffic analyzer and the network negotiating component are combined within a single unit.

16. The system of claim 15, wherein the single unit is a GGSN.

17. The system of claim 14, wherein the traffic analyzer includes a transport layer packet analyzer.

18. The system of claim 14, wherein the traffic analyzer includes an application layer packet analyzer.

19. The system of claim 14, wherein the network negotiating component includes an interface to an SGSN.

20. The system of claim 14, wherein the traffic analyzer determines the QoS level based on subscriber parameters provided by a RADIUS server.
