Abstract

A method, system and apparatus for the selective suspension of real time data exchanges for unreliable network connections. A selective real time data exchange suspension method can include detecting a network outage condition affecting a real time data exchange. As an example, the real time data exchange can be an exchange of speech data provided by a real time speech server over a data communications network. Subsequently, the real time data exchange can be selectively suspended but not terminated. Finally, the real time data exchange can resume when the network outage condition has been alleviated.

Claims

1. A real time data exchange suspension method comprising the steps of:

detecting a network outage condition affecting a real time data exchange;

selectively suspending but not terminating said real time data exchange; and

,

resuming said real time data exchange when said network outage condition has been alleviated.

2. The method of claim 1, wherein said detecting step comprises the step of detecting a loss of a communicative linkage with a real time data server supporting said real time data exchange.

3. The method of claim 1, wherein said detecting step comprises the step of detecting a severe deterioration in link quality of a communicative linkage with a real time data server supporting said real time data exchange.

4. The method of claim 1, wherein said detecting step comprises the steps of:

monitoring a communicative linkage over which said real time data exchange occurs;

observing a network outage in said communicative linkage; and

,

alerting a real time streaming engine to said network outage.

5. The method of claim 1, wherein said selectively suspending step comprises the steps of:

prompting an end user whether to terminate said real time data exchange, or whether to suspend said real time data exchange; and

,

responsive to a selection by said end user to suspend said real time data exchange, suspending but not terminating said real time data exchange.

6. The method of claim 1, wherein said resuming step comprises the steps of:

determining whether said network outage has occurred remotely or locally;

if it is determined that said network outage has occurred locally, performing polling to determine when said network outage has been alleviated locally;

if it is determined that said network outage has occurred remotely, waiting for said network outage to become alleviated remotely; and

,

resuming said real time data exchange when said network outage condition has been alleviated.

7. The method of claim 1, wherein said real time data exchange is an exchange of speech data provided by a real time speech server over a data communications network.

8. A real time data exchange system configured to selectively suspend a real time data exchange responsive to network outages, the system comprising:

a real time streaming engine configured for coupling to a communicative linkage over which real time data is received for processing in a real time data processing application;

a real time data processing application communicatively linked to said real time streaming engine; and

,

prompting logic coupled to said real time data processing application and programmed to selectively choose to suspend or terminate an exchange of real time data responsive to receiving an alert for a network outage in said communicative linkage.

9. The system of claim 8, wherein said real time data is speech data.

10. The system of claim 8, wherein said real time streaming engine implements logic for managing real time protocol (RTP) formatted data over an real time protocol control (RTPC) protocol.

11. A machine readable storage having stored thereon a computer program real time data exchange suspension, the computer program comprising a routine set of instructions which when executed by a machine causes the machine to perform the steps of:

detecting a network outage condition affecting a real time data exchange;

selectively suspending but not terminating said real time data exchange; and

,

resuming said real time data exchange when said network outage condition has been alleviated.

12. The machine readable storage of claim 11, wherein said detecting step comprises the step of detecting a loss of a communicative linkage with a real time data server supporting said real time data exchange.

13. The machine readable storage of claim 11, wherein said detecting step comprises the step of detecting a severe deterioration in link quality of a communicative linkage with a real time data server supporting said real time data exchange.

14. The machine readable storage of claim 11, wherein said detecting step comprises the steps of:

monitoring a communicative linkage over which said real time data exchange occurs;

observing a network outage in said communicative linkage; and

,

alerting a real time streaming engine to said network outage.

15. The machine readable storage of claim 11, wherein said selectively suspending step comprises the steps of:

prompting an end user whether to terminate said real time data exchange, or whether to suspend said real time data exchange; and

,

responsive to a selection by said end user to suspend said real time data exchange, suspending but not terminating said real time data exchange.

16. The machine readable storage of claim 11, wherein said resuming step comprises the steps of:

determining whether said network outage has occurred remotely or locally;

if it is determined that said network outage has occurred locally, performing polling to determine when said network outage has been alleviated locally;

if it is determined that said network outage has occurred remotely, waiting for said network outage to become alleviated remotely; and

,

resuming said real time data exchange when said network outage condition has been alleviated.

17. The machine readable storage of claim 11, wherein said real time data exchange is an exchange of speech data provided by a real time speech server over a data communications network.
