1  ScopeWord‑p. 7
This document specifies the Stage 2 system description for the interworking between a 3GPP system and a Fixed Broadband Access network defined by Broadband Forum to provide the IP connectivity to a 3GPP UE using a WLAN and a H(e)NB connected to a Fixed Broadband Access network.
The specification covers the system description mobility, Policy, QoS aspects between 3GPP and a Fixed Broadband Access network as well as the respective interactions with the PCC frameworks. This document specifies the detailed extension to EPC defined in TS 23.401 and TS 23.402 for supporting Fixed Broadband Access Network. The extension to PCC framework are specified in TS 23.203.

3  Definitions and abbreviationsWord‑p. 8

3.1  Definitions

For the purposes of the present document, the terms and definitions given in TR 21.905 and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905.
3GPP Femto:
Refers to the HNB and HeNB NEs as defined by 3GPP. The HNB GW is always required for the HNB architecture while the HeNB GW is option for the HeNB.
UE local IP address is defined as:
either the public IP address assigned to the UE connected to a BBF access network via a WLAN by the BBF domain in the no-NAT case, or the public IP address assigned by the BBF domain to the NATed RG that is used for this UE.
H(e)NB local IP address is defined as:
either the public IP address assigned to the H(e)NB by the BBF domain in the no-NAT case, or the public IP address assigned by the BBF domain to the NATed RG that is used for this H(e)NB.
Non-seamless WLAN offload (NSWO):
is a capability of a UE supporting routing specific IP flows over the WLAN access without traversing the EPC as defined in TS 23.402, clause 4.1.5.
EPC-routed:
User plane traffic that is routed via a PDN GW in EPC as part of a PDN Connection. EPC-routed applies to non-roaming, roaming with traffic home-routed and roaming with traffic local break-out cases.
