By dissolving more solute?

Explanation:

#"Concentration"# #=# #"Moles of solute"/"Volume of solution"#, and thus it typically has the units #mol*L^-1#. If we want to increase the concentration, we can either (i) reduce the volume of the solution by evaporating or stripping off the solvent (and this is rather hard for aqueous solutions); or (ii) add more solute to the solution to raise its concentration.

I leave it to you as to which is the appropriate means.
