Asynchronous invocation mechanism in session initiation protocol (SIP) server clusters

摘要

Providing SIP application server interoperability, including detecting at a first SIP application server an event necessitating that work be performed in relation to a SIP application session that is managed by a second SIP application server, creating a SIP message object carrying a set of instructions representing the work, and sending the SIP message object for delivery to the second SIP application server and performance of the instructions at the second SIP application server in relation to the SIP application session.

1. A method for SIP application server interoperability, the method comprising:
detecting at a first SIP application server an event; determining that work must be performed in relation to the event, that the event is associated to a SIP application session that is managed by a second SIP application server, and that the work to be performed in relation to the event must be performed by the second SIP application server; creating, responsive to the determination, a SIP message object carrying a set of instructions representing said work; and sending said SIP message object for delivery to said second SIP application server and performance of said instructions at said second SIP application server in relation to said SIP application session; wherein the work to be performed by said second SIP application server includes at least one of: invalidating said SIP application session hosted on said second SIP application server and scheduling a timer task associated with said second SIP application session hosted on said second SIP application server.
