Abstract

Communication sessions may be initialized by sending an initialization request, and the request may include a frame of policy data identifying permissions, prohibitions and/or rules governing a requesting user or computing device's ability to make calls and use communication services. The policy frame of data may be included with the call initialization request for the session, and may be passed along to multiple nodes that receive the call initialization request.

First claim

The invention claimed is:

1. A method comprising:
receiving, by a computing device and from a first device in a first network:
a communication setup request for a communication with a second device in a second network; and
a received policy frame comprising a plurality of values corresponding to a plurality of communication policies associated with the first device,
wherein the first network and the second network use different policy frame values for a first communication policy of the plurality of communication policies;

generating a modified policy frame by modifying a value, in the received policy frame, that is associated with the first communication policy; and
sending, to the second network, the communication setup request and the modified policy frame.

2. The method of claim 1 , wherein the computing device is an intermediate device located between the first network and the second network.

3. The method of claim 1 , wherein the sending the communication setup request and the modified policy frame further comprises:
determining, based on a header in the communication setup request, a next node for establishing the communication, and
sending the communication setup request and the modified policy frame to the determined next node.

4. The method of claim 1 , wherein the modified policy frame is in a header of a packet comprising the communication setup request.

5. The method of claim 4 , wherein the header is a Session Initiation Protocol (SIP) header.

6. The method of claim 1 , wherein one of the plurality of communication policies comprises permissions for two or more data carriers associated with the communication setup request.

7. The method of claim 1 , wherein one of the plurality of communication policies comprises a permission level comprising a first level for calls to a first geographic region and a second level for calls to a second geographic region.

8. A system comprising:
a computing device configured to:
receive, from a first device in a first network:
a communication setup request for a communication with a second device in a second network; and
a received policy frame comprising a plurality of values corresponding to a plurality of communication policies associated with the first device,
wherein the first network and the second network use different policy frame values for a first communication policy of the plurality of communication policies;

generate a modified policy frame by modifying a value, in the received policy frame, that is associated with the first communication policy; and
send, to the second network, the communication setup request and the modified policy frame; and

the second device, wherein the second device is configured to receive the communication setup request and the modified policy frame.

9. The system of claim 8 , wherein the computing device is an intermediate device located between the first network and the second network.

10. The system of claim 8 , wherein the computing device is configured to:
determine, based on a header in the communication setup request, a next node for establishing the communication, and
send the communication setup request and the modified policy frame to the determined next node.

11. The system of claim 8 , wherein the modified policy frame is in a header of a packet comprising the communication setup request.

12. The system of claim 11 , wherein the header is a Session Initiation Protocol (SIP) header.

13. The system of claim 8 , wherein one of the plurality of communication policies comprises permissions for two or more data carriers associated with the communication setup request.

14. The system of claim 8 , wherein one of the plurality of communication policies comprises a permission level comprising a first level for calls to a first geographic region and a second level for calls to a second geographic region.

15. A computer-readable medium storing instructions that, when executed, cause a computing device, to:
receive, from a first device in a first network:
a communication setup request for a communication with a second device in a second network; and
a received policy frame comprising a plurality of values corresponding to a plurality of communication policies associated with the first device,
wherein the first network and the second network use different policy frame values for a first communication policy of the plurality of communication policies;

generate a modified policy frame by modifying a value, in the received policy frame, that is associated with the first communication policy; and
send, to the second network, the communication setup request and the modified policy frame.

16. The computer-readable medium of claim 15 , wherein the computing device is an intermediate device located between the first network and the second network.

17. The computer-readable medium of claim 15 , wherein the instructions that cause the computing device to send the communication setup request and the modified policy frame, when executed, further cause the computing device to perform:
determine, based on a header in the communication setup request, a next node for establishing the communication, and
send the communication setup request and the modified policy frame to the determined next node.

18. The computer-readable medium of claim 15 , wherein the modified policy frame is in a header of a packet comprising the communication setup request.

19. The computer-readable medium of claim 18 , wherein the header is a Session Initiation Protocol (SIP) header.

20. The computer-readable medium of claim 15 , wherein one of the plurality of communication policies comprises permissions for two or more data carriers associated with the communication setup request.
