Zte Terminal Software - Update Framework

Updates are delivered via standard internet protocols, typically over HTTPS to ensure data integrity. The framework supports FOTA (Firmware Over-The-Air) technology, allowing devices to download updates via cellular networks (3G/4G/5G) or Wi-Fi. Advanced implementations of the framework often employ delta updating (differential updating), where only the modified bits of code are downloaded rather than the entire OS image, significantly reducing bandwidth consumption and download time.
