  • Patent number: 4802201
    Abstract: Where a carrier wave is received from a called radio telephone set and where the identification signal of the radio telephone set coincides with a preassigned identification signal, transmission of a paging signal from a base unit is stopped. Even when the identification signals do not coincide with each other, the paging signal is sent continuously over a definite interval. Communication is established only when the signal from a handset to the base station has a predetermined strength and a proper I.D.

  • Patent number: 4796291
    Abstract: A mobile radio communications system for wide area mobile radio communications allows any two remote mobile stations to hold communications by way of a public switching network. A fixed station governing an area in which a calling mobile station is located sends to a switching network its own identification (ID) data and ID data associated with a mobile station which is connected to the fixed station by radio. Based on the two kinds of ID data, a called mobile station sees a telephone number assigned to the calling mobile station and a telephone number assigned to the fixed station which is associated with the calling mobile station.

  • Patent number: 4794635
    Abstract: An improved two-way radio communication system having a limited number of channels is disclosed which assigns calls in a max-minimum method, in a first embodiment according to the type of call and sector to be served. This disclosed first embodiment includes a method that ascertains the type of call, handoff or first assignment, and assigns a server with a given central controller to a channel frequency within the requestor sector that minimizes interference to present users. The method of the second embodiment controls requests for assignment to a limited number of channels to reduce adjacent channel interference to and from the requestor with respect to present users operating on a system by utilizing one or more thresholds to arrange channel assignments based upon progressively larger or smaller values of received signal strength.

  • Patent number: 4792968
    Abstract: For use with a public communication facility C incorporating terminals T1-TN, e.g. a telephone system, a statistical analysis system D interfaces with individual stations where a caller is prompted by voice instructions to provide digital data that is identified for positive association with the caller and is stored for processing. Caller data is confirmed by a look-up table and by a signal-commanded voice generator. Files are created in the analysis system wherein callers are assigned designations which are stored along with statistical and identification data. In one embodiment, callers are identified by calling sequence and assigned designations are provided in the form of an acknowledgment. A break-off circuit enables a caller to terminate the computer interface aborting to a terminal for direct communication with an operator.

  • Patent number: 4777647
    Abstract: An interface (10) is disclosed for coupling a conventional pay station telephone (12) to a telephone switching system (16). The interface (10) provides supervision signal detection functions normally provided by a switching system, and thus can be connected thereto by a less costly business line (28). The interface includes processor controlled tone generators (72, 76) and detectors (73, 74, 81, 106, 108) for detecting tones and voltages transmitted by either the telephone (12) or the switching system (16). The interface (10) further includes a detector (106) and a procedure (FIG. 8) for providing an answer call indication. Coin collection or return is controlled by the interface (10) depending on the status of the call which is also determined by the interface (10).

  • Patent number: 4776001
    Abstract: A method and an apparatus are disclosed for controlling a radio telephone system comprising a single master apparatus connected to a subscriber line and a plurality of radio telephone sets connected to the master apparatus by way of radio channel. When a call origination operation is made by one of the radio telephone sets, a call originating signal is sent to the master apparatus from the call originating radio telephone set. In response to the call originating signal, the master apparatus switches its radio channel to an idle speech channel, and sends a channel designating signal representing the idle speech channel to the plurality of radio telephone sets including the call originating radio telephone set so as to switch the radio channels of the radio telephone sets which have received the channel designating signal to the idle speech channel.
