US 11,700,287 B2 · Snap-in invocation for call reconstruction

Abstract

During a Session Initiation Protocol dialog setup, a media gateway or container executes or initiates two or more applications that provide features during a conference call. The applications are applied to messages or data in the conference call based on a sequence order established during the setup of the conference call. The sequence order and the application identities are stored in a shared database. When a failure occurs during the conference call, the applications are reestablished in the reconstructed or reestablished conference call. The application reconstruction includes reinitiating the applications with the same sequence as previously established before the failure. As such, the user has the same features applied in the same way before and after the failure, which improves the systems performance and expected operation.

Claims20

Dependent claims

A system comprising:

a media gateway including:
a processor;
and
a memory including one or more instructions that when executed by the processor, enable the media gateway to:
determine that a signaling-disrupting event has occurred during a Session Initiation Protocol (SIP) conference call;
reestablish a SIP dialog between a network element and the media gateway;
and
re-initiate two or more applications providing features for the SIP conference call, wherein the two or more applications are associated with a sequence order, and wherein the two or more applications are re-initiated such that the sequence order is maintained.

5 more elements

A machine readable memory having stored thereon instructions that cause a processor to execute a method, the instructions comprising:

an instruction to establish a Session Initiation Protocol (SIP) dialog between a SIP user agent and a media gateway;
an instruction to determine that a signaling-disrupting event has occurred during a SIP conference call having the established SIP dialog;
an instruction to reestablish the SIP dialog between the SIP user agent and the media gateway;
and
an instruction to re-initiate two or more applications providing features for the SIP conference call, wherein the two or more applications are associated with a sequence order, and wherein the two or more applications are re-initiated such that the sequence order is maintained.
