  We show, by numerical calculations, that there exist three-types of
stationary and spherically symmetric nontopological soliton solutions
(NTS-balls) with large sizes in the coupled system consisting of a complex
matter scalar field, a U(1) gauge field, and a complex Higgs scalar field that
causes spontaneously symmetry breaking. Under the assumption of symmetries, the
coupled system reduces to a dynamical system with three degrees of freedoms
governed by an effective action. The effective potential in the action has
stationary points. The NTS-balls with large sizes are described by bounce
solutions that start off an initial stationary point, and traverse to the final
stationary point, vacuum stationary point. According to the choice of the
initial stationary point, there appear three types of NTS-balls: dust balls,
shell balls, and potential balls with respect to their internal structures.
