  • a subscriber to the location determination system (1) equipped with a computer (60) running an Internet browser requests the location of a specific vehicle (22).
  • the subscriber can be a stand-alone user or, for example, a member of a number of licensed subscribers in a given organization, all as required and appropriate.
  • the user logs on to the Web site (50) and selects the vehicle (22) for which the location is sought via the service access form (54).
  • the request is passed from the Web site (50) to the location determination system (1) which accesses the database (2) to determine the appropriate location tracking system (11-14) for the vehicle.
  • the location determination system (1) passes the request and details of the appropriate location tracking system (11-14) to the communication subsystem (3).
  • the communication subsystem (3) formats the request for transmission to the respective location tracking system (11-14) and transmits it via the Internet (30).
  • the location tracking system (11-14) receives the request and determines the location of the vehicle (22). This information is then transmitted back to the communication subsystem (3) via the Internet (30).
  • the communication subsystem (3) associates the information with the request and passes it to the location determination system (1).
  • the location determination system (1) passes the location of the vehicle (22) to the map server (4) which obtains a map of the area in which the vehicle (22) is located using the map engine, marks the position of the vehicle (22) on the map and passes it to the location determination system (1).
  • the map is then passed via the Internet (30) to the Web browser running on the subscriber's computer (60).
  • Figure 3 is a schematic diagram of the system of Figures 1 and 2 illustrating preferred features of the invention.
  • the location determination system (1) may host a WML-based Web site (not shown) on the Internet (30).
  • WAP-enabled mobile telephones (100) and other communication devices can communicate via a WAP server (110) to submit location requests and receive location maps or coordinates.
  • the map server (4) may be linked to map databases (5) in formats such as Raster, Vector, Topographic or aerial photographs.
  • data related to the determined location could also be incorporated in the output.
  • a location data server (120) may be linked to a number of location databases, examples of which include traffic information databases (121), Yellow Pages databases (122) and databases of video of the location (123).
  • the location data server may accept connections and/or data from external data providers via an open content layer (124) that establishes a standard data communication protocol. As an automatic procedure, or upon request of a subscriber, selected or all data on the location determined by the location determination system (1) that is available from the databases is obtained from the location data server (120) by the map server (4) and incorporated in the output map.
  • the location data received by a subscriber is normally an HTML representation of the information requested.
  • This representation may be composed of, for example, HTML and a GIF (image) component.
  • GIF image
  • the invention is not limited to the specific user interface data, which could be made up of, or converted to, any appropriate format.
  • multiple requests for the location of the same entity are detected and processed as one request, the location data being sent to both parties.
  • Multiple requests from one subscriber may be processed so that the locations of the entities are superimposed on one map.
  • each request may result in a location map being displayed in a separate window.
  • the location determination system (1) may also be configured to communicate with external application servers (130) via the Internet, PSTN or other communication medium.
  • the application server may run a proprietary or commercial software system for, for example, supplying navigation information (131), managing movement of resources (132), such as for route planning between multiple destinations, billing and/or advertising (133) and emergency service management (134).
  • the data supplied to the application server (130) may include maps or may just be location coordinates in a predetermined format.
  • the location determination system (1) may also communicate location data to non-Internet based clients. For example, it may be linked to an SMS (Simple messaging service) server (140) and supply locations as coordinates, street names derived from map databases or other location data available to mobile telephones (141), pagers (142) etc.
  • SMS Simple messaging service
  • the communication subsystem (3) is an XML server.
  • Communication with location tracking systems (11-14) is preferably asynchronous. In this manner, as no communication channel or session is held open while the location is determined (which may take anywhere from a few seconds to a number of minutes), the use of system resources and communication costs are limited without any negative effect on the response time of the system.
  • Communication between the communication subsystem (3) and location tracking system (11-14) is preferably made using an open format communication protocol.
  • the protocol is illustrated in the schematic diagram of Figures 4a and 4b.
  • a request protocol data unit is shown.
  • the data unit is transmitted by the communication subsystem (3) to the respective location tracking system (11-14) and includes the field ItemID (200), which contains the location tracking system's identifier of the item to be located.
  • the data unit may also contain a timeslot field (210) designating a point in time for which the location of the item is requested.
  • a location data unit is shown.
  • the data unit is transmitted from the respective tracking system (11-14) to the communication subsystem (3) and includes the fields ItemID (300) and Coord (310).
  • the Coord field (310) may be in Latitude/Longditude format or in UTM format.
  • the data unit may include the optional fields of Accuracy (320) indicating the location accuracy in Meters and Date (330) and Time (340) fields indicating the date and time at which the item was at the specified location.
  • a translation system may be installed at location tracking systems that are not compatible with the open format communication protocol in order to intercept requests from the communication subsystem (3), convert the request to the location tracking system's proprietary format and to convert the location data from the location tracking service back into the open format for transmission to the communication subsystem (3).
  • a single subscriber can access from his home computer (equipped with commercially available browser) a web site (50) and inquire as to location of vehicles or other entities of interest.
  • the vehicles or entities may be spread among more than one company (e.g. they may belong to different groups (21) to (24), each supervised by a respective different location company).
  • the operational center communicates with the Company Location Systems over the Internet, the sought vehicles may be located in remote locations not necessarily in the same country or even continent.
  • the application of the present invention is not bound to motor vehicles and may used for any mobile platform, e.g. for tracking persons.
