Abstract
Abstract A detailed QoS parameter mapping of 3GPP QoS parameters to IEEE 802.21 MIH link QoS parameters. The detailed mapping includes an IEEE 802.21 Supported Number of Class of Service (CoS) parameter to indicate supported 3GPP QoS classes (conversational, streaming, interactive, and background). IEEE 802.21 MIH capable networks may use the detailed mapping to improve access-independent mobility management. A wireless transmit/receive unit (WTRU), an access point, and other network infrastructure capable of performing the detailed QoS parameter mapping are also disclosed.
