Definitions

  • the present invention relates generally to data communications, and more particularly to data communication and dynamic networking between vehicles.
  • the invention may be used in a variety of applications, including news and entertainment broadcasting; direction finding, Internet access; location finding; voice, video and data communications; vehicle tracking, and the like.
  • a presently preferred implementation of the invention provides a network to permit communications between and among moving vehicles, such as automobiles, and fixed stations, such as transceivers.
  • the fixed transceivers could be located, for example, on a specially equipped road system or global positioning satellites (GPS).
  • GPS global positioning satellites
  • a communications unit on each vehicle is capable of transmitting information and receiving information transmitted from other moving or stationary units (e.g., on the specially equipped road system).
  • a preferred embodiment of the communications unit transmits data indicative of its current location, so that each communications unit "knows" the physical location of the other communications units.
  • the communications units preferably employ wireless transmission and reception to communicate with each other.
  • Dynamic IP addressing may be provided such that each communications device is associated with a local network having a local pool of dynamic IP addresses, such that the local pool of dynamic IP addresses is associated with a predefined geographic area or volume in space.
  • Each communications unit is thus uniquely identifiable by an identification number, and each is capable of working together with other units in a coordinated process of transmitting and receiving information.
  • the commumcations unit has a limited wireless transmission range for sending wireless information to another unit. When a transmission is received by a first unit from another unit entering the physical operating range of the first unit, the two (or more) units establish a coordinated information dialog, such as in a data information network, until one of the units leaves the physical operating range or is deactivated or leaves the logical operating range.
  • FIG. 1 depicts one embodiment of a communications unit in accordance with the present invention.
  • Figure 2 depicts an exemplary subnet or workgroup relationship in accordance with the present invention.
  • FIG. 1 depicts an exemplary embodiment of a communications unit display station.
  • the unit includes a built-in color camera 10, color display screen 12, internal GPS receiver and CPU 14, stereo audio speakers 16, audio output jacks 18, user input controls 20, mounting hardware 22, microphone 24, and antenna 26.
  • This device is relatively straightforward to construct, and so we will not describe the hardware of the communications unit in greater detail.
  • the connectivity between communications units can be coordinated using a concept of dynamic subnets or dynamic workgroups, which can be devised upon geographic vicinity or other means.
  • a commumcations unit would determine its current position using a known method such as GPS, and then determine its current geo- id based upon, e.g., a predetermined lookup table or mathematical formula. The geo-id could then be used to determine the unit's current subnet or workgroup setting. Such subnet or workgroup setting may then be used by the commumcations unit to establish itself as a node in a larger network of communications units.
  • the subnet or workgroup setting can also be used in the communications network design to coordinate the dynamic movement of communications units between subnets or workgroups.
  • a diagram depicting an example of possible geo-ids and subnet or workgroup relationships is shown in Figure 2.
  • An adjustable range feature allows the communications units to receive and process or reject transmitted information based upon criteria contained inside each information transmission. Such information may contain criteria be based upon physical geography, such as latitude, longitude and radius of applicability, or it may be based upon logical information, such as group identification (e.g., "all vehicles belonging to our truck fleet"), or combination of criteria ("all vehicles belonging to our truck fleet currently traveling on 1-95 between Phila and NYC”) for applicability.
  • One aspect of the present invention concerns a method of providing dynamic Internet Protocol (IP) addressing in a communications system.
  • IP Internet Protocol
  • a communications device that accesses data from an IP network is associated with a local network having a local pool of dynamic IP addresses.
  • This local pool of IP addresses is associated with a predefined geographic area or volume in space.
  • the inventive method comprises the following acts: determination by a communications device of its current geographic position and a defined geographical boundary; selection of a dynamic IP address from a predetermined pool of LP addresses assigned to the current geographic position's defined geographical boundary; and determining if such dynamic IP address is currently assigned to another communication device within the current geographic boundary.
  • Another aspect of the present invention relates to a method of providing dynamic IP addressing such that the respective communications devices are associated with a local network having a local pool of dynamic LP addresses, such that the local pool of dynamic LP addresses is associated with a predefined geographic area or volume in space.
  • the method includes, determination of the current geographic position of the communications device; assignment of unused dynamic IP address to the communications device; and communicating the assigned IP address to the commumcations device.
  • Yet another aspect of the present invention concerns an addressable group of communications devices created by identifying a contiguous arrangement of distinct geographic areas or volumes, each with a unique identifier, and each with an preassigned pool of IP addresses, which addresses can be dynamically assigned to one or more communications devices inside one of the said geographic areas, resulting in a group of communications devices whose addresses are a subset of the known pool of addresses, thus creating the addressable group of communications devices.
  • the invention also provides a method of providing reassignment of a new dynamic IP address to a commumcations device without disruption of an existing communications session with a remote host via an old IP address.
  • This method includes determining the new IP address while maintaining the existing IP address and communications session; establishing a new communications channel on the communications device, which uses the new IP address; issuing a notification of the new IP address to the remote host, which, upon receipt of such notification, redirects the communications session to the new IP address; and resumption by the communications device of communications with the remote session using the new IP address.
  • the invention further provides a method of establishing data routing between two groups of communications devices. Each group is located in an adjoining geographic area or spatial volume.
  • a communications device maintains two LP addresses, one address belonging to the subset of possible LP addresses preassigned to the first group, and the other address belonging to the set of possible IP addresses preassigned to the second group.
  • the communications device determines the new IP address while maintaining the existing IP address and communication session; establishes a new communications channel on the commumcations device, which uses the new IP address; and issues a notification to members of the group whose possible addresses include the first IP address, and to the group whose possible addresses include the second LP address, that the communications device has established itself as a data router between the two groups.

  • a news discrimination capability that allows each commumcations unit to distinguish information based upon the communications unit's current geographic position and an optional target geography specified in each news broadcast item.
  • a practical application of this news broadcasting system would be to disseminate travel advisories or road condition information. Since the invention has the ability to discern by logical or physical geographic applicability, such travel advisories or road condition information can be very specific to a particular road or stretch of road, and the receiving communications unit can filter in only those broadcasts of interest by specifying filter parameters, such as "Traffic Advisories: 1-95 Southbound between Exit 16 and the Phila International Airport". Such parameter selection can be made easy to use and choose by implementing a user interface such as graphical touch screen, voice activated controls, or memorized settings.
  • Direction System such as graphical touch screen, voice activated controls, or memorized settings.
  • a mobile direction system may use the communications network, permitting requests for directions from a current position to a desired destination.
  • the current position of a communications unit and desired destination could be transmitted to a central direction system that determines and transmits directions to the communications unit, which would display written and graphical directions on its screen.

  • a practical application of the entertainment broadcasting and receiving system would be as an enhancement to the in-vehicle video/audio playback entertainment center accessory currently offered in some vehicles.
  • Position Communication and Display A dynamic position communication and display system can employ the commumcations network.

  • Tracking and Data Logging Electronic vehicle tracking and data logging can be provided by using the communications network, which would perform continuous acquisition of the vehicle's driving profile, such as date, time, location, speed and recording of such data to a storage device located in the vehicle or a remote storage device.

  • the vehicle profiling system could be used to record date, time, location, speed, and relative location of other so equipped vehicles. Using this data, one could determine such parameters as vehicle acceleration, driving distance relative to another so equipped vehicle (i.e., to ascertain tailgating or safe following distances), and even traffic violation situations (i.e., speed beyond posted speed limits, running or jumping red lights at intersections equipped with such device, etc.).

Additional information such as speed, acceleration, and travel paths could assist traffic engineers to further improve the roadways.

Abstract

L'invention concerne un réseau permettant la communication entre des véhicules en mouvement, tels que des voitures, et des stations fixes, telles que des émetteurs-récepteurs. Les récepteurs fixes peuvent se trouver notamment sur un système routier spécialement équipé ou sur des satellites de positionnement global (GPS). Une unité de communications dans chaque véhicule peut émettre des informations et recevoir des informations émises par d'autres unités, fixes ou mobiles, par exemple sur ledit système routier. Dans un mode de réalisation préféré, l'unité de communications émet des données concernant sa position, de telle manière que chaque unité de communications « connaît » l'emplacement physique des autres unités. Afin de communiquer entre elles, les unités de communications utilisent des transmissions sans fil. Un adressage IP dynamique permet d'associer chaque dispositif de communications à un réseau local possédant un ensemble d'adresses IP dynamiques, de telle manière que l'ensemble local d'adresses IP dynamiques est associé à une zone géographique ou un volume prédéfini dans l'espace.
