POSITIONING NETWORK AVAILABILITY AND RELIABILITY BASED ROUTING
First Claim
1. A method comprising:
- determining, at a routing device, a plurality of routes between a source location and a destination location;
for each of the plurality of routes between the source location and the destination location,determining visibility information associated with the route, wherein the visibility information is indicative of availability of at least a threshold number of location reference communication devices along the route, wherein the location reference communication devices communicate reference signals that enable estimating a position of the routing device;
based on the visibility information associated with the route, calculating a reliability rating of the route, wherein the reliability rating is indicative of a reliability of the route and an ability of the routing device to maintain continuous connectivity to the at least the threshold number of location reference communication devices along the route;
comparing the reliability ratings of the plurality of routes to identify one of the plurality of routes with a highest reliability rating; and
causing at least the route with the highest reliability rating to be presented at the routing device.

Abstract
A routing system can be configured to determine a route based on availability and reliability of location reference devices to determine a most reliable route between a source and a destination. Visibility information that is indicative of availability of at least a threshold number of location reference devices along the route can be determined. For each of a plurality of routes between the source and the destination, a reliability rating associated with the route can be determined based on the visibility information associated with the route. The reliability rating is indicative of a reliability of the route and an ability of the routing system to maintain continuous connectivity to the at least the threshold number of location reference devices along the route. The reliability ratings of the plurality of routes are compared to identify and to present one of the plurality of routes with a highest reliability rating.

19. One or more machine-readable storage media, having instructions stored therein, which, when executed by one or more processors causes the one or more processors to perform operations that comprise:
-
determining a plurality of routes between a source location and a destination location; for each of the plurality of routes between the source location and the destination location, determining visibility information associated with the route, wherein the visibility information is indicative of availability of at least a threshold number of location reference communication devices along the route, wherein the location reference communication devices communicate reference signals that enable estimating a position of a routing device; based on the visibility information associated with the route, calculating a reliability rating of the route, wherein the reliability rating is indicative of a reliability of the route and an ability of the routing device to maintain continuous connectivity to the at least the threshold number of location reference communication devices along the route; comparing the reliability ratings of the plurality of routes to identify one of the plurality of routes with a highest reliability rating; and causing at least the route with the highest reliability rating to be presented at the routing device. - View Dependent Claims (20, 21, 22, 23)
