Definitions

  • the present invention relates generally to a personal communication system which employs two-way wireless communication that can only be initiated by, and billed to, a caller.
  • the system uses a method for billing the calling party in a wireless communication system using a one-way signal transfer. More particularly, the present invention is directed to a system which utilizes a subscriber apparatus having pager and radiotelephone functions to generate two-way wireless communication by an outside caller calling a page number wherein the caller is billed for the communication time and the subscriber is unable to incur communication charges due to their inability to initiate or place a call with the apparatus.
  • Mobile radio communication is well known in the art.
  • Cellular radio has spawned Personal Communication Service.
  • PCS is wireless and the user requires no tether such as the wire pair that connects a conventional telephone to a local serving switch.
  • paging systems provide the mobile and ambulatory user with a means of being alerted that someone wishes to contact or talk to that person.
  • the public switched telecommunications network is vast and includes hundreds of national networks that are interconnected to form a gigantic international network.
  • Cellular service is an adjunct to the network.
  • Cellular radio systems provide two-way signaling and communication by usually connecting a mobile terminal to another user through the PSTN where the other user is most commonly a subscriber of the PSTN. Nevertheless, the other user may be a mobile terminal.
  • Most of the connectivity involves connecting wired telephone service to mobile users.
  • the mobile telephone switching office (MTSO) is the heart of a cellular system for a specific serving area.
  • the MTSO is connected to the PSTN by a trunk group. Trunks are the telephone lines connecting one telephone switch or exchange with another.
  • Paging is a one-way radio alerting system that is a simple extension of the
  • PTSN Unlike cellular radio systems, the direction of transmission is from a fixed paging transmitter to an individual. Some pagers have digital readouts which provide the individual with a number to call back while others give a short message or enable a transmitter to leave a voice mail by hooking into a voice mail system.
  • the cordless telephone is another example of a personal communication system.
  • Technology in recent years has resulted in a vast number of cordless telephones, cellular telephones and paging apparatus which exhibit a variety of unique and multiple features.
  • the following described inventions are directed to cellular telephones.
  • U.S. Patent No. 4,908,848 issued to Hanawa discloses an apparatus for a mobile communication system having a handset which can be programmed to lock calls, restrict calls, or time calls.
  • U.S. Patent No. 5,203,009 issued to Bogusz et al. describes a cellular telephone having a fixed calling capacity which limits the use of the phone by only enabling it to call emergency telephone numbers.
  • a similar cellular telephone is described in U.S. Patent No.
  • U.S. Patent No. 4,906,989 issued to Kasugai describes a paging system having a vehicle mounted repeater with a portable paging receiver detachably mounted on the repeater.
  • U.S. Patent No. 4,940,963 issued to Gutman et al. discloses a paging system having a centrally located terminal and a plurality of remote pager units wherein both automatic and manual acknowledge back signaling is provided.
  • U.S. Patent No. 5,040,204 issued to Sasaki et al. discloses a cordless telephone apparatus with a removably mounted pager which reports an incoming signal from a parent device or radiotelephone; ii) U.S. Patent No. 4,747, 1 22 issued to Bhagat et al.
  • a mobile paging call back system which includes a control unit interconnecting a radio pager, a memory, an indicator, a control switch, and an automatic dialer with the control unit including a logic circuit that is programmed to verify valid telephone number information received from a pager, to store the verified data in memory, to activate the indicator to show that valid data has been received and to transfer the stored data to the automatic dialer to reach a mobile radiotelephone; iii) U.S. Patent No. 5, 1 1 7,449 issued to Metroka et al.
  • Parents would be another target market for this system in that it would enable children to be directly connected to their parents upon being paged by their parents without the expense of cellular telephone charges. Such a system would also prevent the accumulation of billings associated with frivolous or unnecessary calls made by children within the system in that the system does not allow for those possessing the apparatus to make outgoing calls. Further, if the apparatus were stolen, it would be impossible to commit further fraud by charging the communication system for calls because the system employs caller generated billing.
  • the caller only generated two-way wireless communication system includes:
  • FIG. 1 shows a block diagram of one example of the electronic circuitry of an apparatus for use with the personal communication system of the present invention which employs two-way wireless communication that can only be initiated by, and billed to, the caller.

  • the microprocessor 1 8 When a signal is received from an outside caller having the correct mobile identification (M.I.D.) number of the pagephone, the microprocessor 1 8 will activate an alert signal such as an audio signal 20 or vibrator 22. If the pagephone is then fully opened (i.e. a flip element is moved into the open position such as with a flip phone), and not in use, a further switch means is activated in the pagephone. Activation of the further switch means enables the microprocessor to activate the readiotelephone transmitter 1 6 so that the pagephone will receive incoming signals and transmit outgoing signals to thereby allow a conversation to take place between the caller and the user of the unit.

When the call is completed the unit is deactivated 1 52 and the air time count is stopped 1 54. The total air time is calculated and recorded and billed to the outside caller's initiating telephone number 1 56. The unit then returns to the sleep mode 1 58.
