Neutral B meson oscillations were established in the B0 system in 1987, while they still remain undiscovered in the Bs system. In a novel approach using the full data set of the DELPHI detector taken at the Z pole from 1992 to 2000 a fully inclusive analysis was done. This was only achieved by exploiting the full capabilities of the DELPHI detector and the application of sophisticated analysis techniques, such as neural networks and quasi random point sets used for resolution integrations.
