name: X2-U
full_form: X2-User plane
context: The S1-C interface supports at least the following functions: - Mobility functions: Support for intra- and inter-system mobility of UE(s). - Connection Management Functions: Functions for handling LTE_IDLE to LTE_ACTIVE transitions, roaming area restrictions etc. - SAE Bearer Management: Setup, modification and release of SAE Bearers. - General S1 management and error handling functions: Request to release, and release of all bearers, S1 reset functions, as well as some kind of path supervision. - Paging of a UE in the eNB. - Transport of NAS information between EPC and UE. - MBMS support functions.
description: The X2-User plane (X2-U) refers to the user plane interface between two base stations or eNodeBs in a Long-Term Evolution (LTE) network. It enables the exchange of user data and control information for bearer setup, modification, and release. The context highlights its role in coordinating UE capabilities, configuring SCG cells, allocating radio resources, and exchanging security information.
explanation: The abbreviation X2-U is classified as an Interface based on the provided context, which describes its functionality in facilitating communication between network entities for bearer management and resource allocation.
