Location tracking framework
A computer-implemented location tracking system includes an index comprising separate organizations of a) entity information and location based notifications for the entities, and b) independent location based notifications, and the index further comprising a spatial organization of references to the entity information, location based notifications for the entities, and independent location based notifications.
1. A computer-implemented location tracking system comprising non-transitory machine memory configured with logic to implement
an index comprising separate organizations of a) entity information and location based notifications for the entities, and b) independent location based notifications; and
the index further comprising a spatial organization of references to the entity information, location based notifications for the entities, and independent location based notifications, the spatial organization separate from organization (a) and organization (b);
the system further comprising:
a wireless interface system to receive and transform wireless signals from multiple mobile devices into location information for entities represented in the index.
2. The computer-implemented location tracking system of claim 1 , wherein the spatial organization of references further comprises:
a tree comprising spatially-organized nodes, each node comprising an entity index and a location based notification index.
3. The computer-implemented location tracking system of claim 2 , wherein the entity index and a location based notification index further comprises:
one or both indexes organized by a most-sparse coordinate value.
4. The computer-implemented location tracking system of claim 2 , wherein the entity index and a location based notification index further comprises:
one or both indexes organized into spatial grids.
5. The computer-implemented location tracking system of claim 1 , further comprising:
logic to compare the location based notifications with more specific geometry for an entity.
6. A computer-implemented location tracking system, comprising:
a computer system;
a network interface;
non-transitory machine memory, the memory comprising:
interface logic to interface with client applications to receive entity location updates;
logic to receive the entity location updates from the interface logic;
logic to form an index comprising separate organizations of a) entity information and location based notifications for the entities, and b) independent location based notifications, the index further comprising a spatial organization of references to the entity information, location based notifications for the entities, and independent location based notifications, the spatial organization separate from organization (a) and organization (b); and
logic to probe the index for location based notifications (LBNs) triggered by the entity location updates.
7. The computer-implemented location tracking system of claim 6 , wherein the spatial organization of references further comprises:
a tree comprising spatially-organized nodes, each node comprising an entity index and a location based notification index.
8. The computer-implemented location tracking system of claim 7 , wherein the entity index and a location based notification index further comprises:
one or both indexes organized by a most-sparse coordinate value.
9. The computer-implemented location tracking system of claim 7 , wherein the entity index and a location based notification index further comprises:
one or both indexes organized into spatial grids.
10. The computer-implemented location tracking system of claim 6 , further comprising:
logic to compare the location based notifications with more specific geometry for an entity.
