METHOD AND APPARATUS FOR HANDLING PROCESSING ERRORS IN TELECOMMUNICATIONS EXCHANGES

摘要

Error handling in a telecommunications exchange (10) is performed in a process centralized fashion. Certain objects (36) in each process are defensively programmed (40) to detect and report errors. One error handler object (38) is provided for each process, with the error handler object receiving (48, 74) the error reports, analyzing (50, 78) the reports and specifiying error recoveries (52, 80) including a default behaviour for recovery from errors based on a default error analysis. In situations where the default analysis and recovery does not adequately address anticipated errors, specialized error analyses and recoveries are designed for and specified by the error handler object.
