PMIPv6 QoS  describes an access-network-independent way to negotiate Quality of Service (QoS) for Proxy Mobile IPv6 (PMIPv6) mobility sessions. IEEE 802.11, Wi-Fi Multimedia (WMM), and Wi-Fi Multimedia - Admission Control (WMM-AC) describe ways to provide QoS for Wi-Fi traffic between the Wi-Fi Station (STA) and Access Point (AP). This document describes how QoS can be implemented in a network where the access network is based on IEEE 802.11 (Wi-Fi). It requires a mapping between QoS procedures and information elements in two segments: 1) the Wi-Fi segment and 2) the PMIPv6 segment. (See Figure 1.) The recommendations here allow for dynamic QoS policy information per Mobile Node (MN) and session to be configured by the IEEE 802.11 access network. PMIPv6 QoS signaling between the Mobile Access Gateway (MAG) and Local Mobility Anchor (LMA) provisions the per-MN QoS policies in the MAG. Further details on policy configuration and the Policy Control Function (PCF) can be found in , Section 6.1. In the IEEE 802.11 access network modeled here, the MAG is located at the AP / Wireless LAN Controller (WLC). Figure 1 below provides an overview of the entities and protocols.

Mapping Quality of Service (QoS) Procedures of Proxy Mobile IPv6 (PMIPv6) and WLAN
This document provides guidelines for achieving end-to-end Quality of Service (QoS) in a Proxy Mobile IPv6 (PMIPv6) domain where the access network is based on IEEE 802.11. RFC 7222 describes QoS negotiation between a Mobile Access Gateway (MAG) and Local Mobility Anchor (LMA) in a PMIPv6 mobility domain. The negotiated QoS parameters can be used for QoS policing and marking of packets to enforce QoS differentiation on the path between the MAG and LMA. IEEE 802.11 and Wi-Fi Multimedia - Admission Control (WMM-AC) describe methods for QoS negotiation between a Wi-Fi Station (MN in PMIPv6 terminology) and an Access Point. This document provides a mapping between the above two sets of QoS procedures and the associated QoS parameters. This document is intended to be used as a companion document to RFC 7222 to enable implementation of end-to-end QoS.
