  2. .21 Paradigm division • IMHO IEEE 802.21 provides two main things • Media Abstraction • Transport Protocol • These two things are currently being specified for Handovers • But it does not have to be this way!!! • Split the specification in these two main functionalities • Explain to other WGs the benefits of using the protocol already defined • Try to be the transport protocol of choice for new standards that need a upper layer transport protocol

  3. Some ideas for future projects related to IEEE • Mapping of QoS classes between technologies • Intermediate layer between applications and new technologies • Example: 802.11aa requires cross-layer communication • Event to change codec • Way of indicating more relevant frames etc.. • It is relevant that IEEE 802.21 continues monitoring other standards and react upon new technologies • IEEE 802.11av supports load management • IEEE 802.11av supports BSS transition mechanisms to indicate possible handover targets

  4. Some ideas related to industry • One problem I see with .21 is that it is not clear how to do things with it • Example: Pretty sure with .21 you can do an automatic handover to home AP but it is not defined how to • Example: How to move load information from APs to MIIS • Maybe it is worth to create a doc explaining how to do certain things in .21 that are relevant to industry or 3GPP

  5. Some ideas regarding IETF • IETF is moving much faster than us • Currently there are several projects which can use .21 • Flow mobility requires a flow manager which can implement .21 • Right now flow mobility is not supported by .21 • 3G offload is getting momentum, we should get this train • Distributed Mobility Management is being created • Need to analyze if .21 supports this concept

  6. Dynamic Mobility Anchoring N: number of flows that do not require mobility F: number of flows that require mobility
