Abstract

Disclosed are a method and system for an intermediate node, which negotiates a Quality of Service (QoS) contract with two or more secondary nodes, to maintain a record of previous contract agreements to use as the basis for future contracts and to select the negotiation order with the secondary nodes based on a configurable rule set. The intermediate node selects the secondary node which is deemed to be (predicted as) most restrictive to begin QoS negotiations. The intermediate node dynamically creates for a specific user a new QoS profile to begin the QoS negotiations based on current system loading and historical QoS precedents.

Claims

1. A system comprising:

a plurality of secondary nodes; and

an intermediate node in communication with a plurality of secondary nodes, the intermediate node being configured to;

maintain a record of a plurality of quality of service (QoS) profile logs for a plurality of users, and

if a negotiation order is restricted, dynamically generate a provisional QoS profile to begin a negotiation process, the provisional QoS profile being based on a most restrictive secondary node.

2. The system according to claim 1, wherein the intermediate node generates the provisional QoS profile for a specific connection a network dictates which secondary node to start negotiations with.

3. The system according to claim 1, wherein generating the provisional QoS profile is performed as a function of historical requested QoS parameters associated with a specific user.

4. The system according to claim 3, wherein the intermediate node is further configured to adjust the provisional QoS profile based on at least one of:

past user QoS acceptance or requests of at least one of the plurality of secondary nodes, and current resource availability.

5. The system according to claim 3, wherein the intermediate node is configured to adjust the provisional QoS profile based on past accepted averages of QoS parameters and current system loading.

6. The system according to claim 5, wherein the intermediate node is configured to apply a weighting factor to the past accepted averages of QoS parameters as a function of time.

7. The system according to claim 1, wherein the intermediate node is configured to predict a most restrictive secondary node of the plurality of secondary nodes and start the QoS negotiation with the predicted most restrictive secondary node.

8. In a communication system, a method comprising:

maintaining, by an intermediate node, a record of a plurality of quality of service (QoS) profile logs for a plurality of users; and

if a negotiation order is restricted, dynamically generating, by the intermediate node, a provisional QoS profile to begin a negotiation process, the provisional QoS profile being based on a most restrictive secondary node.

9. The method according to claim 8, wherein the

dynamically generating the provisional QoS profile is performed when a network dictates which secondary node to start negotiations with.

10. The method according to claim 8, wherein:

dynamically generating the provisional QoS profile is performed as a function of historical requested QoS parameters by or for a specific user.

11. The method according to claim 10, further comprising:

adjusting the provisional QoS profile based on at least one of past user QoS acceptance or requests of at least one of the plurality of secondary nodes, and current resource availability.

12. The method according to claim 10, further comprising:

adjusting the provisional QoS profile based on past accepted averages of QoS parameters and current system loading.

13. The method according to claim 12, further comprising:

applying a weighting factor to the past accepted averages of QoS parameters as a function of time.

14. The method according to claim 8, further comprising:

predicting which secondary node of the plurality of secondary nodes is most restrictive for a QoS negotiation; and

starting the QoS negotiation with the secondary node predicted as the most restrictive.

15. A non-transitory computer-readable medium storing instructions executable by a processor for performing a method comprising:

maintaining a record of a plurality of quality of service (QoS) profile logs for a plurality of users; and

if a negotiation order is restricted, dynamically generating a provisional QoS profile to begin a negotiation process, the provisional QoS profile being based on a most restrictive secondary node.

16. The non-transitory computer-readable medium of claim 15, wherein the dynamically generating the provisional QoS profile is performed when a network dictates which secondary node to start negotiations with.

17. The non-transitory computer-readable medium of claim 15, wherein dynamically generating the provisional QoS profile is performed as a function of historical requested QoS parameters by or for a specific user.

18. The non-transitory computer-readable medium of claim 17, the method further comprising:

adjusting the provisional QoS profile based on at least one of current system loading and past accepted averages of QoS parameters.

19. The non-transitory computer-readable medium of claim 18, the method further comprising:

applying a weighting factor to the past accepted averages of QoS parameters as a function of time.

20. The non-transitory computer-readable medium of claim 15, the method further comprising:

predicting which secondary node of the plurality of secondary nodes is most restrictive for a QoS negotiation; and

starting the QoS negotiation with the secondary node predicted as the most restrictive.
