Three were presented by Wehrle for the 'Open Source IMSI-catcher' project \cite{dennis} and one by Federrath \cite{mueller}.
The attacks differ on whether the \gls{ms} already is in normal cell selection mode or not, \ie it is connected to another \gls{bts}.
-\paragraph{\gls{ms} is in normal cell selection mode:}
+\paragraph{MS is in normal cell selection mode:}
The \gls{imsi}-catcher has to emulate a cell configuration of the provider the target \gls{ms} is looking for broadcasting at any frequency.
If the \gls{ms} stumbles upon the frequency it will connect.
This is no method with 100\% accuracy however chances can be raised by broadcasting with higher power.
Some \gls{imsi}-catchers even broadcast at a higher power than it would be allowed for normal \gls{bts} \cite{imsi_wiki} to make certain to be the strongest base station available to the \gls{ms}.
-\paragraph{\gls{ms} is already connected to a network:}
+\paragraph{MS is already connected to a network:}
If this is the case then the connection to the current cell needs to be broken.
It can be achieved either by jamming the frequency band of the cell the \gls{ms} is connected to thus forcing the \gls{ms} into cell selection or by getting the \gls{ms} to switch the cell to the catcher's.
This can be done the following way.
