Persistence of interrupted calls
View Patent ↗A system for recovering an unintentionally interrupted call in a telephony network includes an interrupted call data capturer and a re-connector. The interrupted call data capturer is deployable in the telephony network and configured to capture data pertaining to an interruption of the call from the telephony network. The re-connector is associated with the interrupted call data capturer and configured to use the captured data to automatically reconnect at least one unintentionally disconnected participant of the call, thereby recovering the unintentionally interrupted call.
1. A system for recovering an unintentionally interrupted call in a telephony network, the system comprising:
a network component that comprises a capturing portion that captures an unintentional call disconnection event between a first participant and a second participant in the telephony network; and
a re-connector portion that establishes a temporary connection to hold the first participant in the network, while an attempt is made to reconnect the second participant to the call.
2. The system of claim 1 , wherein said re-connector portion keeps said first participant of the call connected while reconnecting said unintentionally disconnected second participant, and connects said disconnected second participant and said-first participant to recover the unintentionally interrupted call.
3. The system of claim 1 , wherein said re-connector portion temporarily diverts said first participant via said temporary connection to a media server until successfully reconnecting said unintentionally disconnected second participant.
4. The system of claim 1 , wherein said re-connector portion disconnects said first participant upon failing to reconnect said unintentionally disconnected second participant within a predefined period of time.
5. The system of claim 4 , wherein the predefined period of time is determined by a subscriber to the telephony network.
6. The system of claim 1 , wherein said re-connector portion verifies that said first participant is reconnected, and wherein the verification is accomplished by at least one of using a call establishment retry, polling to a Home Location Register (HLR), polling to a Visitor Location Register (VLR), and registering to an event of a Network Serving Entity.
7. The system of claim 1 , wherein said capturing portion captures data pertaining to an interruption resultant upon disconnection of a second participant of the call therefrom to determine that said disconnection is unintended by said first participant.
8. The system of claim 1 , wherein said capturing portion captures said data pertaining to said interruption of the call according to a predefined capturing policy.
9. The system of claim 1 , wherein the telephony network is selected from the group consisting of a mobile phone telephony network, an Intelligent Network (IN) based telephony network, and an Internet Protocol Multimedia Subsystem (IMS) based telephony network.
10. A method for recovering an unintentionally interrupted call in a telephony network, comprising: a) capturing data pertaining to an interruption of the call between a first participant and a second participant from the telephony network and; b) keeping the first participant connected while an attempt is made to reconnect to the second participant; and c) automatically reconnecting the first participant to the second participant of the call, thereby recovering the unintentionally interrupted call.
11. The method of claim 10 , further comprising: temporarily diverting said first participant to a media server until successfully reconnecting said unintentionally disconnected participant.
12. The method of claim 10 , further comprising: disconnecting said first participant upon failing to reconnect said unintentionally disconnected participant within a predefined period of time.
13. The method of claim 12 , wherein the predefined period of time is set by a subscriber of the telephony network.
14. The method of claim 10 , further comprising: verifying that said second participant is reconnected, wherein the verification is accomplished using at least one selected from the group consisting of using a call establishment retry, polling to a Home Location Register (HLR), polling to a Visitor Location Register (VLR), and registering to an event of a Network Serving Entity.
15. The method of claim 10 , further comprising: before the reconnecting, determining that said disconnection is unintended by said unintentionally disconnected second participant.
16. The method of claim 10 , further comprising: defining a capturing policy, wherein said capturing data pertaining to said interruption of the call is carried out according to said capturing policy.
17. The method of claim 10 , wherein the telephony network is selected from the group consisting of a mobile telephony network, an Intelligent Network (IN) based telephony network, and an Internet Protocol Multimedia Subsystem (IMS) based telephony network.
18. The method of claim 10 , further comprising playing a predetermined message to the first participant of the call connected while reconnecting said unintentionally disconnected second participant.
19. The method of claim 12 , wherein the predefined period of time is set by an administrator of the telephony network.
