  We obtain a (5+2)-dimensional global flat embedding of the (3+1)-dimensional
curved RN-AdS space. Our results include the various limiting cases of global
embedding Minkowski space (GEMS) geometries of the RN, Schwarzschild-AdS in
(5+2)-dimensions, Schwarzschild in (5+1)-dimensions, purely charged space, and
universal covering space of AdS in (4+1)-dimensions, through the successive
truncation procedure of parameters in the original curved space.
