full_form: Serving Gateway Control Plane
context: SGW-C sends a trigger over LI_T3 to the BBIFF-U present in the SGW-U to deactivate the delivery of UP packets associated with the IMS voice media bearer to the LMISF-CC. The trigger includes the XID associated with the Task. The BBIFF-U present in the SGW-C continues to capture and deliver the UP packets from the IMS signalling bearer to the LMISF-IRI over the LI_X2_LITE reference point The LMISF-IRI examines the received UP packets and examines the SIP message included within those packets for any target match. When there is no target match, the LMISF-IRI extracts and stores the SIP message. This is normal process before any interception is activated (see figure 4.8.4-4). However, the BBIFF-U does not deliver the UP packets from the IMS media bearer. The BBIFF-C present in the SGW-C detects that IMS media bearer is deleted for inbound roaming UEs with home-routed roaming. The BBIFF-C present in the SGW-C notifies the LMISF-IRI about the bearer deletion notification over the
description: The Serving Gateway Control Plane (SGW-C) manages and controls the flow of user plane packets in the Evolved Packet Core (EPC) network. It intercepts and delivers packets to the Lawful Interception Management System (LIMS) for processing.
explanation: The text describes SGW-C's role in packet management and interaction with other network components like LIMS, which are characteristic of a Network Function.
