802.21
Discussion on next steps for
3 main lines were discussed
Achieving QoS integration between different technologies
Currently there is no common view on how to manage handover with QoS requirements between different technologies
QoS concepts and metrics between technologies differ within IEEE and between IEEE and 3GPP for example
Define a common QoS framework between technologies
It might be just a translator
Extended capability discovery
IEEE technologies provide tech-specific mechanisms for service/capability announcement
These mechanism are not homogeneous and cannot be easily extended
Examples:
Indication of VoIP support in an AP, LTE or WiMAX PoA
Emergency service support
This can also be seen as an extension of MIIS providing a way of determining the handover relevant capabilities of a target PoA before handover.
Extended and dynamic MIIS
One of the things that ANDSF cannot do is providing dynamic information
A new extended version of MIIS may provide not only static information but e.g. dynamic load information of the APs
Concepts such as hierarchical MIIS, Localized caches and dynamic reporting (even updates of MIIS based on events) may be interesting from the operators point of view
Adding policies to MIIS should also be analyzed
