IEEE Standard for Information Technology-Telecommunications and information exchange between systems-Local and Metropolitan networks-specific requirements-Part II: Wireless LAN Medium Access Control (MAC) and Physical Layer (PHY) specifications: Amendment 9: Interworking with External Networks

This amendment specifies enhancements to the IEEE 802.11 medium access control (MAC) that support wireless local area network (WLAN) interworking with external networks. It enables higher layer functionalities to provide overall end-to-end solutions. The main goals of this amendment are aiding network discovery and selection, enabling information transfer from external networks, enabling emergency services, and interfacing subscription service provider networks (SSPNs) to IEEE 802.11 networks that support interworking with external networks.
