Abstract

An exemplary management method includes receiving at a first network a notice of an intended communication to a called party network, the notice including a first priority indicator, the intended communication requiring a resource for supporting a streaming data protocol in each network between a calling party network and the called party network; forwarding the notice to a second network and toward the called party network, the notice including the first priority indicator; in parallel with said forwarding, mapping the first priority indicator to a second priority indicator and initiating for the intended communication a determination of resource availability for the first network based on the second priority indicator; determining the determination of resource availability for the first network based on the second priority indicator, wherein the determination is for a first resource for the first network; and verifying resource availability for the intended communication.

Claims

1. A method comprising:

receiving at a first network a notice of an intended communication to a called party network, the notice of intended communication including a first priority indicator, wherein the intended communication requires a resource for supporting a streaming data protocol in each network between a calling party network and the called party network;

forwarding the notice of an intended communication to a second network and toward the called party network, the notice of intended communication including the first priority indicator;

in parallel with said forwarding, mapping the first priority indicator to a second priority indicator and initiating for the intended communication a determination of resource availability for the first network based on the second priority indicator;

determining for the intended communication the determination of resource availability for the first network based on the second priority indicator, wherein the determination is for a first resource for the first network; and

verifying resource availability for the intended communication.

2. The method of claim 1 wherein the mapping of the first priority indicator to the second priority indicator is based on values negotiated via a key exchange protocol.

3. The method of claim 1 wherein the mapping of the first priority indicator to the second priority indicator is based on values negotiated via a key exchange protocol between the first network and the calling party network.

4. The method of claim 1 wherein the mapping of the first priority indicator to the second priority indicator is based on predetermined values.

5. The method of claim 1 wherein the mapping of the first priority indicator to the second priority indicator is based on at least one default.

6. The method of claim 1 wherein the first priority indicator is included in a resource priority header.

7. The method of claim 1 wherein determining for the intended communication the determination of resource availability for the first network based on the second priority indicator comprises:

reserving for the intended communication the first resource for the first network in the event the first resource is available for the intended communication.

8. The method of claim 1 wherein determining for the intended communication the determination of resource availability for the first network based on the second priority indicator comprises:

reserving for the intended communication the first resource for the first network in the event the first resource is available above a threshold level.

9. The method of claim 1 wherein the notice of intended communication includes a personal identification number, the method further comprising:

replaying an authentication of the intended communication based on the personal identification number.

10. The method of claim 9 wherein the mapping the first priority indicator to a second priority indicator maps the first priority indicator to a default priority indicator in the event a value for the personal identification number is unknown.

11. The method of claim 1 wherein signaling for the determination of resource availability for the first network based on the second priority indicator includes both the first priority indicator and the second priority indicator.

12. The method of claim 1 wherein verifying resource availability for the intended communication comprises:

receiving for the intended communication from a third network a second indication of resource availability; and

wherein the verifying is based on the determination of resource availability for the first network and the second indication of resource availability.

13. The method of claim 1 further comprising:

forwarding a re-invite for the intended communication in the event verifying resource availability for the intended communication indicates availability of resources from the calling party network to the called party network.

14. A method comprising:

receiving at a first network a notice of an intended communication to a called party network, the notice of intended communication including a first priority according to a first priority scheme, wherein the intended communication requires at least one resource for supporting a streaming data protocol between a calling party network and the called party network;

mapping the first priority to a corresponding second priority for a second priority scheme utilized in the first network;

verifying resource availability of at least one resource in the first network based on the corresponding second priority; and

in parallel with said verifying, forwarding the notice of an intended communication to a second network and toward the called party network prior to receiving an first indication of resource availability of the at least one resource in the first network required for the intended communication.

15. The method of claim 14 wherein the mapping of the first priority to the corresponding second priority is based on negotiation via a key exchange protocol between the first network and the calling party network.

16. The method of claim 14 wherein the mapping of the first priority to the corresponding second priority is based on predetermined correspondences.

17. The method of claim 14 wherein the mapping of the first priority to the second priority is based on a default correspondence.

18. The method of claim 14 wherein the notice of intended communication includes a resource priority header.

19. The method of claim 14 further comprising:

receiving at the first network a second indication of resource availability of at least one resource at a third network required for the intended communication.

20. The method of claim 19 further comprising:

forwarding a re-invite of the intended communication to the second network and toward the called party network in the event the first indication and the second indication indicate resource availability for at least one resource in each network from the calling party network to the called party network.
