Description: GTP-C, or GPRS Tunneling Protocol for Control Plane, is a fundamental protocol in mobile networks, especially in the 5G architecture. Its main function is to manage control signaling between network elements, facilitating communication between the user and the network infrastructure. GTP-C allows for the establishment, modification, and release of tunnels used for data transmission, which is essential for the efficient transmission of real-time information. This protocol operates in the control plane, meaning it handles the signaling functions necessary for managing user connections, ensuring that data is transmitted securely and efficiently. GTP-C is part of a broader set of GTP protocols, which includes GTP-U (for user data transmission) and GTP’ (for statistics collection). The implementation of GTP-C is crucial for ensuring service quality in mobile networks, where latency and speed are critical factors. Its design allows for interoperability between different generations of mobile network technologies, facilitating the transition to more advanced technologies and ensuring a seamless user experience.
