Definitions

  • This invention relates generally to communication and database systems and, in particular, to a system and a method for having multiple databases interact with each other.
  • Global telecommunication systems such as the IRIDIUM System, provide a subscriber with the ability to make and receive a phone call or page anywhere in the world.
  • Such global telecommunication systems have to track where each of the subscribers is located for determining where to route the subscriber's telephone calls and pages, for determining how to bill the subscriber, and for allowing a subscriber to originate a telephone call in a foreign country.
  • the subscriber equipment including but not limited to satellite cellular phones and satellite pagers, has to interact with the telecommunication provider equipment to communicate location information to the telecommunication provider so that it can determine the current location of the subscriber. In the event that the subscriber equipment is inoperative because it is turned off or the battery is dead, the location information cannot be provided by the equipment. Accordingly, there is a significant need for a system and method that obtains subscriber information, including location information, from other sources not directly associated with the telecommunication system.
  • FIG. 1 shows a high level diagram of a system where a telecommunication system interacts with multiple service providers according to a preferred embodiment of the present invention
  • FIG. 2 shows an example of a highly simplified diagram of a telecommunication system
  • FIG. 3 shows a method for having the telecommunication system interact with multiple service providers.
  • FIG. 1 shows a high level diagram of system 5 where telecommunication system 6 interacts with multiple service providers 7 according to a preferred embodiment of the present invention.
  • system 5 comprises telecommunication system 6 coupled to multiple service provider 7 by connection 8.
  • Each service provider 7 is coupled to at least one database 9.
  • Telecommunication system 6 includes global satellite-based telecommunication providers, such as the IRIDIUM system and the Globalstar system for example, as well as terrestrial-based telecommunication providers.
  • Telecommunication system 6 is capable of supplying one or a combination of voice communication (i.e., telephone and cellular phone calls), paging services and /or facsimile services.
  • Service providers 7 comprise a variety of providers of services, including but not limited to resorts, hotels, credit card companies, airline companies, rental car companies, cable TV companies and restaurants. Service providers 7 may also include other space-based and terrestrial- based telecommunication providers of voice and paging services. Each service provider 7 is coupled to a database 9 where information on a user (i.e., subscriber) may be stored. Although only one database is shown in FIG. 1, there may be multiple databases servicing a single service provider 7.
  • Connection 8 comprises a variety of ways for telecommunication provider 6 to interface with multiple service providers 7, including but not limited to optical communication devices, microwave communication devices, radio frequency devices, and land lines. Land lines may include the Internet. These types of connections 8 are well known to those skilled in the art.
  • Databases 9 are devices capable of storing information about customers. This information may include, but is not limited to users' addresses, telephone numbers, credit cards, bank accounts, and location information. Databases 9 are coupled to service providers 7 and telecommunication system 6. Although FIG. 1 shows a single database 9 servicing a sole service provider 7, in alternative embodiments, multiple databases 9 may service one service provider 7 or a single database 9 may service multiple service providers 7. Similarly, multiple databases 9 may service telecommunication system 6. Databases 9 are well known and many varieties and sizes are commercially available.

  • a “satellite” comprises geostationary, low-earth and medium-earth orbiting satellites and/or any combination thereof.
  • a “constellation” means a number of satellites arranged in orbits for providing specified coverage (e.g., radio communication, remote sensing, etc.) of a portion, portions or all of the earth.

For example, there may be one base station located in Honolulu, another base station located in Los Angeles and another base station in Washington, D.C. Another example is to have separate base stations located in each country on the earth. Base stations 40 may provide satellite signalling commands to satellite 20 so that satellite 20 maintains its proper position in their orbit and perform other essential house-keeping tasks. Base stations 40 may be additionally responsible for receiving voice and/or data from satellites 20.

For telecommunication providers 6, this step could include looking for the information in database 9 based on the user information sent by the requester.
  • This step 104 may also include determining what subscriber unit is owned by or associated with the subscriber, and using the subscriber unit information, sending a request from the base station to the telecommunication system to find the location of the subscriber's subscriber unit.
  • Finding the location of the subscriber unit may be based on GSM protocols and obtaining the HLR (home location register) information and /or VLR (visiting location register) information from the base station or another base station in the telecommunication system.

Abstract

L'invention concerne un système (5) et un procédé (100) qui permettent de localiser un abonné et de transmettre l'information de position à un système demandeur de l'information. Un prestataire de services (7) (société émettrice de carte de crédit, société de location de véhicules, par exemple) adresse à un système de télécommunications (6) une demande de localisation d'un abonné. Le système de télécommunications (6) vérifie que le prestataire de services est habilité à obtenir l'information demandée et, dans l'affirmative, le système de télécommunications (6) localise l'unité appartenant ou associé à l'abonnée (30). L'information est transmise au prestataire de services (7). De même, un système de télécommunications (6) peut adresser à un prestataire de services (7) une demande de localisation d'un abonné. Si le système de télécommunications (6) est habilité à obtenir l'information demandée, le prestataire de services (7) détermine le dernier endroit où l'abonné a fait appel à ses services (par exemple, achat avec une carte de crédit, vol sur une compagnie aérienne, etc.) et transmet cette information de position au système de télécommunications (6).
