Abstract

Techniques for notification for a prioritized media path for a communication session are described. According to various embodiments, a communication session is authenticated with a communication service. The communication service interacts with an Internet Protocol (IP) network and a wireless access network to cause the communication session to be routed across a prioritized media path.

Claims

1. A system comprising:

at least one processor; and

one or more computer-readable storage media including instructions stored thereon that, responsive to execution by the at least one processor, cause the system perform operations including;

ascertaining one or more attributes of a communication session that is initiated between a client device and an endpoint device;

determining that the communication session is authenticated for a prioritized media path;

forming a notification that includes the one or more attributes and an indication that the communication session is authenticated for a prioritized media path; and

communicating the notification to a network proxy to cause the communication session to be marked with a prioritized class of service indicator and to be routed from a standard wireless channel to a prioritized wireless channel for receipt by the endpoint device.

2. A system as recited in claim 1, wherein said determining comprises determining that a user of the client device is authenticated for the prioritized media path.

3. A system as recited in claim 1, wherein the system is configured to perform the operations in real-time while the communication session is in progress.

4. A system as recited in claim 1, wherein the system is configured to perform the operations without handling data of the communication session.

5. A system as recited in claim 1, wherein said forming comprises populating an application programming interface (API) with the one or more attributes, and wherein the notification is formatted at least in part with the API.

6. A system as recited in claim 1, wherein said communicating further causes the communication session to be routed from a standard routing path across an Internet Protocol (IP) network to a prioritized routing path across the IP network.

7. A system as recited in claim 1, wherein the operations further include:

receiving an indication of a session problem in the communication session; and

communicating a notification to cause the communication session to be rerouted from the prioritized wireless channel to a different wireless channel.

8. A system as recited in claim 1, wherein the operations further include:

receiving an indication of a session problem in the communication session;

forming a notification indicating that the communication session is to be rerouted; and

communicating the notification to the network proxy to cause the communication session to be rerouted from the prioritized wireless channel to a different wireless channel.

9. A computer-implemented method, comprising:

ascertaining one or more attributes of a communication session that is initiated between a client device and an endpoint device;

determining that the communication session is authenticated with a communication service for a prioritized media path;

forming a notification that includes the one or more attributes and an indication that the communication session is authenticated for a prioritized media path; and

communicating the notification to a network proxy to cause the communication session to be marked at an Internet Protocol (IP) network with a prioritized class of service indicator and to be routed at a radio access network from a standard wireless channel to a prioritized wireless channel for receipt by the endpoint device.

10. A method as described in claim 9, wherein said forming comprises:

populating an application programming interface (API) with the one or more attributes; and

generating the notification using the populated API.

11. A method as described in claim 9, wherein said communicating comprises communicating the notification while the communication session is in progress.

12. A method as described in claim 9, wherein said communicating comprises communicating the notification separately from a media flow of the communication session.

13. A method as described in claim 9, wherein said communicating further causes the communication session to be routed from a standard routing path across the IP network to a prioritized routing path across the IP network.

14. A method as described in claim 9, further comprising:

receiving an indication of a session problem in the communication session; and

communicating a notification to the network proxy to cause the communication session to be rerouted from the prioritized wireless channel to a different wireless channel.

15. A method as described in claim 9, further comprising:

receiving an indication of a session problem in the communication session; and

communicating the notification to cause the communication session to be rerouted from a current routing path across the IP network to a different routing path across the IP network.

16. A system comprising:

one or more processors;

a communication component configured to receive one or more attributes of a communication session that is initiated between a client device and an endpoint device; and

at least one module that is executable by the one or more processors to;

determine based on the one or more attributes that the communication session is authenticated with a communication service for a prioritized media path;

form a notification that includes the one or more attributes and an indication that the communication session is authenticated for a prioritized media path; and

communicate the notification to a network proxy to cause the communication session to be marked at an Internet Protocol (IP) network with a prioritized class of service indicator and to be routed at a radio access network from a standard wireless channel to a prioritized wireless channel for receipt by the endpoint device.

17. A system as described in claim 16, wherein the at least one module is configured to communicate the notification separately from a media flow of the communication session.

18. A system as described in claim 16, wherein the at least one module is configured to communicate the notification in real-time while the communication session is in progress.

19. A system as described in claim 16, wherein the at least one module is configured to communicate the notification to cause the communication session to be remarked from a current class of service indicator to the prioritized class of service indicator.

20. A system as described in claim 16, wherein the at least one module is configured to communicate the notification to cause the communication session to be routed from a standard routing path across the IP network to a prioritized routing path across the IP network.
