GTP-U stands for GPRS Tunneling Protocol – User Plane. It is a protocol used in 3G and 4G mobile networks to encapsulate and transport user data packets over the IP-based core network. GTP-U is primarily used to transmit data traffic between the mobile device or base station and the serving gateway, allowing for efficient and secure data transfer. It ensures reliable delivery of user data packets by providing features such as packet sequencing, error detection, and retransmission. GTP-U is a key component in the mobile network infrastructure for enabling data services and internet connectivity for mobile subscribers.
GTP-U stands for GPRS Tunneling Protocol – User plane. It is a protocol used in mobile networks, specifically in the packet core network, to tunnel user data packets between the base station and the gateway. GTP-U is used in 3G and 4G networks to transport user data traffic, such as internet browsing and multimedia content. It encapsulates user data packets within GTP-U headers, allowing them to be transported over the IP-based network. GTP-U is responsible for the efficient delivery of user data packets while maintaining the necessary quality of service and security measures.
