name: SGW-U
full_form: Serving Gateway User Plane
context: ActivateTask is received, then the BBIFF-C shall send the trigger at the time Activation Task is received from the LIPF. The details of ActivateTask sent to the BBIFF-U present in the SGW-U are shown in table 7.10.3.5-2. Table 7.10.3.5-2: ActivateTask message for triggering the BBIFF-U in the SGW-U When the BBIFF-C present in the SGW-C detects that the PDN connection is released (e.g. when SGW-C receives the Sx: Session Release Response from the SGW-U), it shall send a deactivation message to the BBIFF-U present in the SGW-U over the LI_T3 interface, if the task is still active in the BBIFF-U. The BBIFF-C present in the SGW-C shall also send the deactivation message to the BBIFF-U present in the SGW-U when a DeactivateTask is received from the LIPF for the XID if the task is still active in the BBIFF-U.
description: The Serving Gateway User Plane (SGW-U) is a network function responsible for handling user plane traffic in the Evolved Packet Core (EPC) and 5G core networks. It provides connectivity between the Radio Access Network (RAN) and the Packet Data Network (PDN), enabling data transmission between the UE and external networks.
explanation: SGW-U is classified as a Network Function based on its role in managing user plane traffic within the network, as highlighted by the context. The text mentions SGW-U as a component that interacts with other network functions like BBIFF-C and LIPF, further solidifying its classification as a Network Function.
