This paper addresses 3D geo-location for fifth generation wireless systems. It is discussed how a standardized location reporting format could be augmented with vertical information, without a need for signaling of map information. The paper shows how surface models can be constructed from such an augmented polygon location reporting format, to represent the 3D geography on the support of the interior of the polygon. A new 3D time-difference-of-arrival hybrid positioning algorithm is proposed, in which the vertical degree of freedom of the mobile is replaced by the proposed surface model. This enables 3D time-difference-of-arrival positioning based on only three time of arrival measurements. A simulated performance evaluation over 10 rural cells in hilly terrain with three time of arrival measurements indicates that the proposed surface model can reduce the horizontal and vertical errors by more than 80 %, as compared to when no vertical model is used.
