Decision-based map-agnostic navigation routing
First Claim
Patent Images
1. A method comprising:
- receiving a route request, from a navigation device, between a starting location and a destination location;
determining, using a processor, a navigation route from the received route request;
generating an encoded navigation route comprising a sequence of path decisions with a path decision at each intersection between the starting location and the destination location, each path decision having a pair of values representing a number of outlets at the respective intersection and an outlet to-be-taken at the respective intersection; and
transmitting the encoded navigation route to the navigation device,whereby a map agnostic navigation route is encoded and transmitted.

Abstract
Systems, apparatuses, and methods are provided for determining a navigation route. A route is requested by a navigation device between a starting location and a destination location. The route request is received by an external processor for analysis. A navigation route is determined by the external processor and its associated map version. The determined navigation route is then encoded with a sequence of path decisions along the route. The encoded navigation route is transmitted to the navigation device.

10. A method comprising:
-
requesting, using a navigation device, a navigation route between a starting location and a destination location; receiving an encoded navigation route based on the request, the encoded navigation route comprising a sequence of path decisions comprising a path decision at each intersection between the starting location and the destination location, each path decision having a pair of values representing a number of outlets at the respective intersection and an outlet to-be-taken at the respective intersection; analyzing the encoded navigation route, using a processor of the navigation device, to determine whether the sequence of path decisions is compatible with a map version of the navigation device; and decoding and displaying the navigation route when the sequence of path decisions is compatible with the map version. - View Dependent Claims (11, 12, 13, 14)

-
at least one processor; and at least one memory including computer program code for one or more programs;
the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to at least perform;receive, from a navigation device, a route request between a starting location and a destination location; determine a navigation route; encode the navigation route with a sequence of path decisions comprising a link identifier agnostic path decision at each intersection between the starting location and the destination location, each path decision having a pair of values representing a number of outlets at the respective intersection and an outlet to-be-taken at the respective intersection; and transmit the encoded navigation route to the navigation device. - View Dependent Claims (16, 17, 18, 19)

20. A navigation device comprising:
-
at least one processor; and at least one memory including computer program code for one or more programs;
the at least one memory and the computer program code configured to, with the at least one processor, cause the navigation device to at least perform;request a navigation route between a starting location and a destination location; receive an encoded navigation route based on the request, the encoded navigation route comprising a sequence of path decisions comprising a link identifier agnostic path decision at each intersection between the starting location and the destination location, each path decision having a pair of values representing a number of outlets at the respective intersection and an outlet to-be-taken at the respective intersection; and identify whether the sequence of path decisions is compatible with a map version of the navigation device. - View Dependent Claims (21, 22, 23, 24)
