Mobile operators deploy Proxy Mobile IPv6 (PMIPv6) [RFC5213] to enable network-based mobility management for mobile nodes (MNs). Users can access IP-based services from their mobile device by using various radio access technologies. The currently supported mobile standards have adequate support for QoS-based service differentiation for subscriber traffic in cellular radio access networks. QoS policies are typically controlled by a policy control function, whereas the policies are enforced by one or more gateways in the infrastructure, such as the local mobility anchor (LMA) and the mobile access gateway (MAG), as well as by access network elements. Policy control and in-band QoS differentiation for access to the mobile operator network through alternative non-cellular access technologies are not supported in the currently specified standards. Although support for IP session handovers and IP flow mobility across access technologies already exists in cellular standards [TS23.402], QoS policy handovers across access technologies has not received much attention so far.

Quality-of-Service Option for Proxy Mobile IPv6
This specification defines a new mobility option, the Quality-of- Service (QoS) option, for Proxy Mobile IPv6. This option can be used by the local mobility anchor and the mobile access gateway for negotiating Quality-of-Service parameters for a mobile node's IP flows. The negotiated QoS parameters can be used for QoS policing and marking of packets to enforce QoS differentiation on the path between the local mobility anchor and the mobile access gateway. Furthermore, making QoS parameters available on the mobile access gateway enables mapping of these parameters to QoS rules that are specific to the access technology and allows those rules to be enforced on the access network using access-technology-specific approaches.
