  2. Abstract • This presentation motivates discussion on possible scopes in TGai Akira Yamada, NTT DOCOMO, Inc.

  3. TGaiPAR Overview[1] • 5.2 Scope: This amendment defines modifications to the IEEE 802.11 Medium Access Control Layer (MAC) to enable a fast initial link set-up of IEEE 802.11 stations (STAs). • 5.5 Need for the Project: The number of mobile devices incorporating IEEE 802.11 is steadily growing. Applications that are continuously running on those devices benefit from the high data rates of the IEEE 802.11 interface.The project's primary need comes from an environment where mobile users are constantly entering and leaving the coverage area of an existing extended service set (ESS). Every time the mobile device enters an ESS, the mobile device has to do an initial link set-up to establish wireless local area network (LAN) connectivity. This requires efficient mechanisms that(a) scale with a high number of users simultaneously entering an ESS(b) minimize the time spent within the initial link set-up phase(c) securely provide initial authentication.The current IEEE 802.11 specification does not meet these requirements in some usage scenarios. An optimization of the link set-up is desirable. Optimizations may include improvements to* access point / network discovery,* secure authentication,* mechanisms to support concurrency in the exchange of higher layer protocol messages during the authentication phase (for example assignment of IP addresses). Detailed technological scopes of TGai are necessary to be discussed e.g. What functions do we need to modify/enhance/create Akira Yamada, NTT DOCOMO, Inc.
