Abstract
Various embodiments relate to the generation and/or use of a positioning map comprising instances of neighbor-cell information that each comprising, are associated with, and/or indexed by a respective globally unique identifier. In an example embodiment, a processor determines a locally unique identifier and an estimated location of an observed neighbor cell. The processor defines a globally unique identifier for the neighbor cell comprising the locally unique identifier and an indication of the estimated location of the neighbor cell. The processor generates a positioning map to include an instance of neighbor-cell information corresponding to the neighbor cell. The instance of neighbor-cell information comprises, is associated with, and/or is indexed by the defined globally unique identifier. The instance of neighbor-cell information may be accessed via an observed locally unique identifier when determining a position estimate for a computing entity that observed a neighbor cell corresponding to the observed locally unique identifier.
