HIGH AVAILABILITY TAKE OVER FOR IN-DIALOG COMMUNICATION SESSIONS

摘要

When a communication session is established, a primary sequenced application is sequenced into the communication session. At some point, the primary sequenced application fails. Before the communication session has been reestablished, an in-dialog message is received for the first communication session. In response to determining that the primary sequenced application has failed and receiving the in-dialog message for the first communication session, reestablishment of the first communication session is expedited to a backup sequenced application. The communication session is reestablished. This allows a communication session that was normally going to be dropped to stay established, thus providing higher reliability over current systems.

主权项

1. A method comprising:
determining that a primary sequenced application has failed, wherein the primary sequenced application is sequenced into a first communication session between a first communication device and a second communication device; receiving an in-dialog message for the first communication session; and in response to determining that the primary sequenced application has failed and receiving the in-dialog message for the first communication session, expediting reestablishment of the first communication session to a backup sequenced application.
