Network Voice Quality Enhancement Database Management

The patent applies preliminary action by analyzing call data and determining VQE function requirements during off-peak periods before the actual peak periods occur. The system pre-processes call data, identifies which calls will benefit from VQE functions, and stores these determinations in a database. During peak periods, the system simply retrieves pre-determined VQE requirements from the database rather than performing complex analysis in real-time, thus maintaining call quality while preserving processing capacity.

The patent applies local quality by selectively applying VQE functions only to specific calls that benefit from them, rather than applying them universally to all calls. The system analyzes call data to identify particular calls with quality issues and applies VQE functions locally to those specific calls based on stored determinations, avoiding the unnecessary processing load that would result from applying VQE functions to all calls regardless of need.

The patent applies self-service by enabling terminals to autonomously signal their type and VQE requirements to the network, eliminating the need for the network to maintain a comprehensive external database of terminal types. The terminal itself provides the necessary information about its capabilities and requirements, simplifying network-side database maintenance while still achieving quality uniformity across different terminal types.
