Disclosed is a route planning method for a navigation system. The method comprises: performing grid processing on an actual geographic space, the grids being cells in a cellular network, acquiring a mobile station cell handover record, and creating a cell adjacency model according to the mobile station cell handover record; making a source and a destination in the actual geographic space correspond to a source grid and a destination grid after the grid processing, and determining a grid-level path from the source grid to the destination grid according to the inter-grid adjacency model; and converting the grid-level path into an actual route from the source to the destination in the actual geographic space. Also disclosed is a route planning device for a navigation system.
