Abstract
An Intelligent Network (IN) switch for use in a communications network. The Intelligent Network (IN) switch comprises N call application nodes capable of executing a plurality of primary-backup group (PBG) applications. Each of the plurality of primary-backup group applications comprises a primary call process and a backup call process, wherein the each primary call process executes an originating half-call model application and a terminating half-call model application associated with a call connection. Each primary call process comprises a primary call instance data (CID) table for storing call instance data used by the originating half-call model call application and the terminating half-call model application. Each backup call process comprises a backup call instance data (CID) table capable of being updated to mirror the call instance data stored in the primary CID table.
