摘要：

I summarize the determination of neutrino oscillation parameters within the three-flavour framework from world neutrino oscillation data with a date of May 2006, including the first results from the MINOS long-baseline experiment. It is illustrated how the determination of the leading 'solar' and 'atmospheric' parameters, as well as the bound on theta(13) emerge from an interplay of various complementary data sets. Furthermore, I discuss possible implications of sub-leading three-flavour effects in present atmospheric neutrino data induced by Delta m(21)(2) and theta(13) for the bound on theta(13) and non-maximal values of theta(23), emphasizing, however, that these effects are not statistically significant at present. Finally, in view of the upcoming MiniBooNE results I briefly comment on the problem to reconcile the LSND signal.
