-Emergency services
-Emergency Call and Network Alert support at the link level QoS mapping distribution SSPN interface service between the AP and the SSPN The generic advertisement service (GAS), described in 4.5. 10, provides both support for a STA’s network discovery and selection, and support for a conduit for communication by a non-AP STA with other information resources in a network before joining the wireless LAN. The interworking service supports emergency services by providing methods for users to access emergency services via the IEEE 802.11 infrastructure, advertising that emergency services are supported (see 1 1.25.6) and identifying that a taffic stream is used for emergency services.
The interworking service provides QoS mapping for SSPNs and other extemnal networks. Since each SSPN or other external network might have its own layer-3 end-to-end packet marking practice (e.g, differentiated services code point (DSCP) usage conventions), a means to remap the layer-3 service levels to a common over-the-air service level is necessary. The QoS Map service provides STAs a mapping of network-layer QoS packet marking to over-the-air QoS frame marking (i.e, user priorty). The SSPN Interface service supports service provisioning and transfer of user permissions from the SSPN to the AP. The method and protocol by which these permissions are transferred from the SSPN are outside the scope of this standard.IEEE 802.11aq pdf download.
