name: FW
full_form: Firewall
context: The candidate solution must co-exist with the existing 3GPP access and FW traversal mechanisms. Also, the candidate solutions must be invoked only when the existing 3GPP access and FW traversal mechanisms are unable to provide a path for the IMS services through the NIMSFW.
description: A Firewall (FW) is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. In the context of 3GPP, FW refers to a network function responsible for protecting the network from unauthorized access and malicious activities.
explanation: The classification of FW as a Network Function is justified by its role in controlling and securing network traffic, as mentioned in the context of co-existence with existing 3GPP access mechanisms and traversal through the NIMSFW.
