Abstract

A system and method for ring delay on a user agent. A destination user agent may receive a request from an origination user agent to establish a session between the two user agents. The destination user agent may delay ringing according to a ring delay parameter. If the request has not been terminated by the time the ring delay parameter is met, the destination user agent may ring and a session may occur between the origination user agent and destination user agent. If the request is terminated before the ring delay parameter is met, the destination user agent may never ring. The ring delay parameter may be a ring delay time period. The ring delay parameter may be received as part of the request from the origination user agent, set by the destination user agent, or set by a service provider for the destination user agent.

Claims

1. A computer-implemented method, comprising:

receiving a request to establish a session between an origination user agent and a destination user agent; and

using one or more processors, delaying ringing at the destination user agent according to a ring delay parameter.

2. The method of claim 1, wherein the ring delay parameter comprises a ring delay time period.

3. The method of claim 2, further comprising:

ringing the destination user agent once the ring delay time period is reached,

providing an indication to the origination user agent that the destination user agent is ringing,

providing an indication to the origination user agent that the session can begin, and

establishing the session.

4. The method of claim 2, further comprising:

receiving an indication that the origination user agent terminated the request before the ring delay time period was reached.

5. The method of claim 1, wherein the request comprises the ring delay parameter.

6. The method of claim 5, wherein the request comprises a Session Initiation Protocol (SIP) invite message with a header comprising the ring delay parameter.

7. The method of claim 1, wherein the ring delay parameter is set by the destination user agent.

8. The method of claim 1, wherein the ring delay parameter is set by a service provider for the destination user agent.

9. The method of claim 1, wherein the ring delay parameter comprises an instruction to delay ringing for requests from any user agent.

10. The method of claim 1, wherein the ring delay parameter comprises an instruction to delay ringing for requests from any user agent not in a contact list of the destination user agent.

11. A non-transitory computer readable medium comprising code to perform the steps of the methods of claim 1.

12. A computer-based system, comprising:

a request receipt module that receives a request to establish a session between an origination user agent and a destination user agent; and

a ring delay module that delays ringing at the destination user agent according to a ring delay parameter.

13. The system of claim 12, wherein the ring delay parameter comprises a ring delay time period.

14. The system of claim 13, further comprising:

a ring module that rings the destination user agent once the ring delay time period is reached,

a communication module that provides an indication to the origination user agent that the destination user agent is ringing and provides an indication to the origination user agent that the session can begin, and

a session module that establishes the session.

15. The system of claim 13, further comprising:

a termination module that receives an indication that the origination user agent terminated the request before the ring delay time period was reached.

16. The system of claim 12, wherein the request comprises the ring delay parameter.

17. The system of claim 16, wherein the request comprises a Session Initiation Protocol (SIP) invite message with a header comprising the ring delay parameter.

18. The system of claim 12, wherein the ring delay parameter is set by the destination user agent.

19. The system of claim 12, wherein the ring delay parameter is set by a service provider for the destination user agent.

20. The system of claim 12, wherein the ring delay parameter comprises an instruction to delay ringing for requests from any user agent.
