Network Simulation Engine for Mobile App Testing

The patent creates virtual copies of cellular network conditions through a network simulation engine that replicates real-world network scenarios including signal strength variations, bandwidth changes, and network drops. Instead of physically transporting devices to multiple locations, the system copies and simulates diverse network environments in a controlled setting, thereby maintaining measurement accuracy while eliminating the complexity of multi-location testing infrastructure

The patent introduces a network simulation engine as an intermediary between the mobile device and the actual cellular network. This intermediary component receives real network data, processes it through simulation algorithms, and delivers controlled network conditions to the device under test. The intermediary layer enables accurate performance measurement without requiring direct connection to multiple physical network locations, thus reducing testing complexity while preserving measurement fidelity

The patent performs preliminary actions by collecting real cellular network data from various locations beforehand and storing it in a database. The network simulation engine then retrieves this pre-collected data and uses it to simulate authentic network conditions during testing. This preliminary data collection and simulation setup eliminates the need for time-consuming on-site testing while maintaining test result reliability, as the simulation is based on actual measured network characteristics

The patent enables continuous testing by maintaining a persistent network simulation environment that can rapidly switch between different simulated network conditions. Unlike physical location testing which requires setup, travel, and teardown at each site, the simulation system provides uninterrupted testing across multiple virtual locations, significantly reducing total testing time while maintaining continuous data collection and analysis

The patent creates a universal testing platform where a single physical testing environment can simulate multiple different network conditions and locations through the network simulation engine. The system uses real network data from various geographic locations to create virtual representations of those environments, allowing one testing setup to achieve the comprehensiveness of multiple physical locations. This multi-functional approach eliminates the need for separate testing facilities at each location, dramatically reducing testing costs while maintaining comprehensive coverage

The patent achieves diverse testing scenarios by dynamically changing network parameters such as signal strength, bandwidth, latency, and packet loss rates through the simulation engine. Instead of physically moving to different locations to obtain varied network conditions, the system modifies these parameters programmatically to create authentic network scenarios. This parameter-based approach provides comprehensive testing coverage across multiple virtual locations using a single physical setup, eliminating the high costs associated with multi-location physical testing
