Description: GTP-U, or GPRS Tunneling Protocol for User Plane, is a fundamental protocol in mobile networks, especially in the 4G and 5G architectures. Its main function is to facilitate the transmission of user data across the network, allowing data to flow efficiently and securely between the end user and the network. GTP-U is responsible for encapsulating data packets, ensuring they are transmitted correctly through the network infrastructure. This protocol is part of the GTP protocol suite, which also includes GTP-C (Control) and GTP’ (for charging data transfer). GTP-U is essential for managing mobility and quality of service in mobile networks, as it allows the creation of data tunnels that can adapt to changing network conditions. Its design enables the scalability and flexibility needed to support the growing volume of data traffic in the 5G era, where the demand for high-speed and low-latency services is expected to increase significantly. In summary, GTP-U is a key component that ensures the efficient and secure transmission of data in modern mobile networks.
