name: IPsec
full_form: Internet Protocol Security
context: For LWIP, the IP Packets transferred between the UE and LWIP-SeGW are encapsulated using IPsec in order to provide security to the packets that traverse WLAN. The end to end path between the UE and eNB via the WLAN network is referred to as the LWIP tunnel. A single IPSec tunnel is used per UE for all the data bearers that are configured to send and/ or receive data over WLAN. Each data bearer may be configured so that traffic for that bearer can be routed over the IPsec tunnel in only downlink, only uplink, or both uplink and downlink over WLAN. The operator needs to know the performance regarding user data transmission via WLAN for LWIP.
description: Internet Protocol Security (IPsec) is a suite of protocols used to secure internet communications by encrypting and authenticating each IP packet in a data stream. In the context of Long-term Wi-Fi integration with Packet Core (LWIP), IPsec is utilized to encapsulate IP packets transmitted between User Equipment (UE) and LWIP Security Gateway (LWIP-SeGW), ensuring security for packets traversing Wireless Local Area Networks (WLAN).
explanation: IPsec is categorized as a Protocol because it defines the rules and processes for securing internet communications, specifically by encrypting IP packets. This aligns with the context provided from 3GPP TS 32.425, where IPsec's role in securing data transmission over WLAN for LWIP is highlighted.
