Definitions

  • the present invention relates generally to two-way radio communication systems, and more particularly to such a communication system which includes the capability of establishing a communication link via point-and-address techniques.
  • Two-way communications as well as the infrastructure and signalling protocols to support such two-way communications, are well established in the prior art.
  • Two-way communications systems include land-line telephone systems, radio, cellular telephony, and a myriad of combinations of these and other such systems. Communications systems of this type have been developed to satisfy the need for one communicator to communicate with a known second communicator. Examples of two-way communications include a police dispatcher calling a patrol officer, an individual placing a telephone call to a friend, and two computers sending data back and forth between remote locations.
  • a common problem with most two-way communications lies in the requirement for the sending communicator/device to know the identity (phone number, radio ID, etc.), for the receiving communicator. That is, the sending communicator must know ahead of time the identification (ID) of the device through which the receiving communicator will accept the call.
  • the infrastructure of the communications system can store the ID'S associated with receiving candidates for retrieval by the sending communicator. But even this arrangement presumes that the first communicator at one point knows the ID of the communicator it wishes to communicate with.
  • the explicit input, or stored and subsequent retrieval, of the receiving end ID has proven to be an undesirable bottleneck in the process of establishing a communication link between two communication devices.
  • the single-most difficult problem with the radio communications systems of today is the low level of the selectivity that the transmitting device is capable of. That is, every signal which is transmitted from the transmitting device can be received by any suitably equipped receiver within range of the transmitting devices signalling power.
  • this type of operation is perfectly acceptable when the receiving units are associated with the same group as is the transmitting unit (e.g., police officers, construction workers, etc.).
  • the receiving unit's identification is not known (receiving unit is not a member of the same group as the transmitting unit), it is impossible to reach that user.
  • the desire to communicate with another user is brought on by seeing the individual (e.g., a passing motorist on the highway). Even though this individual may be carrying a communication device, communication with that individual is currently impossible unless the communication identification (ID) for the communication unit the individual is carrying is known.
  • ID communication identification
  • Another example of this scenario might be when a family on vacation is driving past a hotel which has a vacancy.
  • the driver recognizing the name as being the same as one which is renowned for its reasonable rates, is unable to see the displayed telephone number for the hotel. Supposing the driver wishes to reserve what might be the last vacant hotel room, he must first find a local directory containing the telephone number, and then call the hotel to make the reservation. Alternatively, he might call directory assistance and acquire the phone number that way. Either way, however, requires additional time and effort in determining the telephone, or access, number for the unknown target.
  • the present invention encompasses a method for use in a point-and-address communication system which uses a two-way communication device having directional probe means to establish a communication link.
  • the method includes the step of transmitting, via the probe means, a request signal directionally toward a receiving device.
  • the request signal is then received by the receiving device, which device is in view of the user of the communication device.
  • the receiving device then initiates a process which results, either directly or indirectly, in transmission of the requested target information to the communication device.
  • the communication unit then receives the requested information corresponding to the receiving device that was seen by the user of the communication device.

  • FIG. 1 shows a so-called point and address transmitter (PAT) 100 in accordance with the present invention.
  • the PAT 100 might have many of the same features of today's radio communications transceivers, including a signal processor 111, alpha-numeric keypad 101, an earpiece 102, a microphone 103, and card reader 110.
  • PAT 100 also includes a conventional antenna 104 for transmitting and receiving radio frequency (RF) signals.
  • RF radio frequency
  • the PAT 100 is equipped with a probing device 106 which, while being aimed at a particular receiving device, directionaliy transmits a request signal.
  • the probing device 106 takes the form of a highly sensitive directional antenna which is capable of selectively transmitting a request signal to a receiving device, later described, which is located anywhere within the operators visual range (e.g., line of sight ranging from 0-200 feet).
  • a directional antenna functionally similar to part number HPX1-220 manufactured by Andrew Corp., is employed to provide the transmitter with selective capability (in an alternate embodiment, this capability could be provided by an infrared transmitting device).
  • Engaging button 107 might be used to activate the probing device 106, which device then transmits the aforementioned request signal. The request signal then propagates substantially toward a particular receiving device, which the operator of the PAT 100 intends to receive the request signal.
  • the type of request being made by the first communicator e.g., return call, service info, service call, operation, etc.
  • the PAT 100 might optionally be equipped with a light beam guide 105 which would serve as a feedback mechanism in determining whether or not the desired target has been properly engaged (a condition typically referred to as being locked) by the PAT 100. This feedback means would aid in the selection process when the PAT 100 is trying to isolate a particular receiving device to which the request signal is to be transmitted.
  • PAT 100 might be equipped with a display screen 108, which might be used to display system messages, prompts, target characteristics, etc.
  • FIG. 2 shows a simplified block diagram of a point and address receiving (PAR) device 200 in accordance with the invention.
  • Antenna 206 is suitable for receiving directional request signals 202 and transmitting, where necessary, information back to the communication device (PAT 100), or to any number of other network services.
  • PAR 200 might also be equipped with a display screen 204, on which system messages, prompts, request status indicators, etc. could be displayed.
  • icon area 207 depicts a graphical symbol describing the type of service(s) provided through a particular receiving device 200. That is, the display 204 and the icon area 207 provide for the requestor, via ocular inspection, pertinent system information without the requestor having to know anything more than the physical location of the PAR device 200.
  • Signal processing unit 205 in addition to performing common signal processing functions, decodes the inbound request signal 202, and subsequently encodes the outbound signals (e.g. wireline tones, RF signals, etc. Required for that particular request.
  • outbound signals may be directed to a wireless network via signal 203, such as a service provider, stand alone operation, wide area network (WAN), etc.
  • PAR 200 may also be hard-wired to a wire-line network, such as the public switched telephone network (PSTN), a private voice/data link, etc.
  • PSTN public switched telephone network
  • receiving device 200 may further be coupled to a service data base 201 which contains information about the types of.
  • the point and address transmitter and receiver (PAT and PAR, respectively) pair may be used to perform a number of tasks which are contemplated by the present invention. These tasks include, but are not limited to, obtaining the target device ID, initiating a service for the requestor, remotely activating an operation for the requestor, and providing the requestor with supplemental information about goods or services. All of these tasks have in common the fundamental premise of a requestor requesting from a receiver, via a process which involves physically aiming a communication device, to obtain information associated with a particular receiving device. That is, it is not important that the requestor know the ID of the receiver, but only that the requestor is able to physically aim the PAT device 100 towards the PAR device 200.
  • FIG. 3 shows a simplified block diagram of a process by which a requesting communication device (PAT 301) is able to acquire the communication ID of a particular target, namely receiving device 302.
  • PAT 301 is physically aimed toward the receiving device 302, and a request signal 303 is transmitted.
  • receiving device 302 After receipt of the request signal 303, receiving device 302 transmits an appropriate target information response (e.g.,, the communication ID associated with receiving device 302).
  • the communication device 301 receives the target information and operates on it accordingly (e.g., establishes a communication link with receiving device 302, stores the information, etc.).
  • Communication types contemplated by the present invention include, voice and data communication, as well as any other such entity which falls into the category of so-called multi-media transmissions.
  • An example of the foregoing embodiment might be a scene on a rural highway where a stranded motorist seeks assistance. It would be impractical, indeed impossible, for the -stranded motorist to know the mobile telephone access number for each passing motor vehicle (whose driver would be in the best position to provide immediate assistance). In a particular embodiment of the present invention, the stranded motorist need only point his PAT 301 toward an oncoming vehicle to establish a communication link between himself and the driver of the vehicle.
  • a point-and-address receiver (PAR) 302 located in the oncoming vehicle after receiving the request signal 303, either directly contacts (e.g., return telephone call) the PAT device 301 (via the PAT 301 device ID sent as part of the request signal), or sends the PAT 301 its communication ID (as part of the target information 304). In the latter case, the PAT 301 would then be able to contact the PAR 302 by automatically dialing the received communication ID.
  • the oncoming vehicle may be equipped with both a PAR 302 and a PAT 301 , perhaps even in the same physical housing, to provide fully point-and-address capability.
  • FIG. 4 shows a simplified block diagram of a process whereby the receiving device establishes a communication link or initiates a communication, between a requestor and a remote service provider.
  • Communication device 401 transmits a request signal 405 towards receiving device 402.

Knowing the communication ID for device 401, the service provider 403 is able to communicate, e.g., using communication link 404, with communication device 401.
  • An example of this alternate embodiment might be that of a limousine service system.
  • a business traveler may be at an unfamiiiar airport and looking for a limousine to transport him to a hotel.
  • the traveler can simply point his PAT 401 towards a receiving device 402 located on a wall in the airport terminal.
  • Receiving device 402 in this case, might have a limousine icon (i.e., a pictorial representation, preferably one which is well recognized), or some other identifiable symbol or label to associate it with the type of service to be provided.
  • the receiving device 402 then relays the communication ID of PAT 401 to a local limousine service (e.g., 403).
  • a local limousine service e.g., 403
  • the limousine service then contacts the traveler and arranges for him to be picked up at a particular location in the airport.
  • a service is provided without the traveler having to know the telephone number of the limousine service, or relying on the assistance of any third party.
  • FIG. 5 shows a simplified block diagram of a process by which a stand alone operation is remotely activated by the receiving device.

Abstract

Selon un procédé utilisé dans un système de communication du type à pointage et adressage, l'on utilise un dispositif de communication bidirectionnel (100) pourvu d'une sonde directionnelle (106) pour établir une liaison de communication. Le procédé consiste à transmettre (706) de manière directionnelle, par l'intermédiaire de la sonde (106), un signal de demande (303, 405, 504, 605) vers un dispositif récepteur (200). Le signal de demande (303, 405, 504, 605) est alors reçu (801) par le récepteur (200), celui-ci pouvant être vu par l'utilisateur du dispositif de communication (100). Le récepteur (200) déclenche ensuite un processus (808, 809) dont le résultat est la transmission d'information cible demandée (304, 404) vers le dispositif de communications (100), soit directement, soit indirectement. Ledit dispositif (100) reçoit alors les informations demandées (304, 404) se rapportant au récepteur (200) qui a été vu par l'utilisateur du dispositif de communication (100).
