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 Slide 3 Slide 3 Clint Chaplin, Samsung Electronics Page 3 Page 3 Clint Chaplin, Samsung Electronics Clint Chaplin, Samsung
