Definitions

  • the present invention pertains to communication systems in which messages can be efficiently retransmitted and more specifically to apparatus and methods for efficiently retransmitting substantially any desired messages from a communication terminal to remote receivers and for processing calls to send additional, stored information.
  • the message is fixed in the memory prior to use and can only be changed by either dismantling the pager and exchanging the complete memory with a new memory in which the new messages are pre-stored, or by dismantling the radio and reprogra ming the memory to erase the old messages and pre-store any new messages desired.
  • this requires the pager user to return the pager to the dealer or paging company and may require an extended period of waiting.
  • a message such as an important customer's phone number is changed, the pre-stored system becomes useless since the pre-stored message is no longer valid.
  • the paging terminal may send the call-back or CLI number as all or part of the message data to be displayed by the pager, but present paging terminals do not process the number to obtain further information which could be sent to the pager either with or in lieu of the number itself.
  • a communication system including a communication terminal having a transmitter and a plurality of remote receivers, at least one of which contains an erasable, nonvolatile memory coupled into the receiver to store received messages in a predetermined position in the memory in response to the receipt of an activation signal and to communicate the stored message to the receiver operator each time the storage address of the message is transmitted to the remote receiver.
  • the communication terminal controls the memory and the storage, as well as the modification or complete omission, of the information therein.
  • FIG.l is a functional block diagram of a paging system
  • FIG.2 is a functional block diagram of a single pager in the paging system of FIG.l.
  • a typical communication system including a communication terminal with a transmitter and a plurality of remote receivers.
  • the communications system is a paging system 10.
  • Paging system 10 includes a paging terminal 15 with a transmitter 18 and a plurality of pagers 20, 21, and 22. Since the detailed operation of a paging system is well known to those skilled in the art, such details will not be elaborated upon herein, except to say that pages are called in to paging terminal 15 on devices such as telephone 25 and these pages are then transmitted by transmitter 18 to one or more of the pagers in the usual manner.
  • the received calls are already in digital form or are converted to digital signals by an analog-to-digital (A/D) converter in a central processing unit (CPU) 26 or in an input buffer circuit 28.
  • A/D analog-to-digital
  • CPU 26 simply provides the address of the specific pager which is to receive the information, along with the information, to transmitter 18 and the message is transmitted to the correct pager in the usual and well known manner.
  • the present invention is utilized when the caller indicates that the information is to be stored in the pager, or group of pagers, for future retransmissions of the same message.
  • paging terminal 15 is an automatic terminal, then the caller will indicate his preference by some method, such as providing special digits along with the information to be stored and the number (address) of the specific pager or group of pagers to be paged.
  • paging terminal 15 is controlled by an operator, then the caller may simply inform the operator that the information is to be stored in the pagers. In either case, it may also be necessary to exhibit some authorization to cause the information to be stored in the pagers, which again may be a type of password.
  • the specific details of these features will change with different communications systems and can easily be devised by those skilled in the art so that no further description is required herein.
  • Incoming messages from telephone 25 are received in some form of input apparatus such as, for example, a simple input port or the buffer 28, which is essentially a temporary storage device and may include an A/D converter if necessary.
  • Messages stored in buffer 28 are conveyed by a data and address bus system to CPU 26, a memory 30, and a decoder 32, which may be included as a part or function of CPU 26.
  • CPU 26 is connected by means of the data and address bus system to transmitter 18, memory 30, and an activation circuit 34.
  • Activation circuit 34 is also coupled directly to decoder 32 by means of the data and address bus system.
  • Transmitter 18 transmits signals to pagers 20, 21, and 22 through an antenna 36.
  • Pager 20 receives a transmitted message from pager terminal 15 by way of an antenna 50.
  • the received message is conveyed to a receiver 52 which filters, amplifies, and converts the signals to appropriate digital signals for use in the remainder of pager 20.
  • the output signals from receiver 52 are supplied to a pager/group address decoder 54 which passes only signals addressed to pager 20, either as an individual or as a member of a group.
  • a complete description of apparatus and methods for coding page transmissions is available in U.S. patent No. 4,518,961, entitled "Universal Paging Device With Power
  • address decoder 54 supplies the information, which may be call-back numbers, words, or any combination thereof, to a message decoder 56.
  • the information is also supplied to a temporary memory 58 where it is stored for a short period of time or until the pager operator clears the page.
  • Message decoder 56 is designed to separate addresses from alphanumeric information which may be accomplished on the basis of length of the message (addresses will be much shorter than any alphanumeric information) , position of the address and alphanumeric information in the message, or a specific identifying code that accompanies one or both of the address and the alphanumeric information.
  • Any address in the message is sent to an erasable, nonvolatile memory 60 on a lead 61 and the alphanumeric information is sent by way of an OR gate 62 to a transponder for converting the electrical signals to human detectable signals, in this embodiment a visual display 64.
  • the alphanumeric signals are also supplied to an input terminal 65 of memory 60.
  • Address decoder 54 also passes an activation signal to an erase and reprogra circuit 68, if an activation signal is included in the received message.
  • An address on lead 61 activates the addressed portion of memory 60 so that any information stored in memory 60 at that address is supplied to visual display 64 by way of OR gate 62.
  • circuit 68 causes the addressed portion of memory 60 to be erased and prepared for storage of the alphanumeric information supplied to input 65 with the alphanumeric information subsequently being stored at the addressed location.
  • Erasable, nonvolatile memory 60 is, for example, an EEPROM type of memory or similar device.
  • a call is made by way of telephone 25 to paging terminal 15 requesting that pager 20 be paged.
  • the caller identifies pager 20 by its specific address and inputs alphanumeric information, which may be, for example, "CALL YOUR OFFICE".
  • the pager address and alphanumeric information is supplied to CPU 26 and the pager address is supplied to memory 30 to activate the portion of memory 30 dedicated to that subscriber.
  • CPU 26 compares the present alphanumeric information to any information stored for that subscriber. If no similar information is found in memory 30, CPU 26 orders transmitter 18 to transmit the pager address and alphanumeric information to pager 20.
  • an authorization code peculiar to pager 20, individually or in a group is also inputted with the pager address and the alphanumeric information.
  • CPU 26 compares the authorization code to a code stored in memory 30 and when verified stores the alphanumeric information in the portion of memory 30 dedicated to the subscriber of pager 20. Also, CPU 26 selects an address from the addresses available in memory 60 of pager 20. Since all of the information stored in the dedicated portion of memory 30 also includes the address at which the same information is stored in memory 60, this selection process is a relatively simple comparison.
  • decoder 32 has detected the authorization signal and upon a verification signal from CPU 26, causes activation circuit 34 to produce an activation signal. It will of course be apparent that all of these functions could be programmed into CPU 26, or that CPU 26 as described, could be substantially replaced with a comparator and some control logic. Transmitter 18 now transmits a message including the address of pager 20, an activation signal, an address for memory 60, and alphanumeric information. When the message is received by pager 20 and is passed by address decoder 54, the activation signal is supplied to circuit 68, the memory address is supplied to memory 60 on lead 61, and the alphanumeric information is supplied to input terminal 65 and display 6 .
  • the alphanumeric information is stored in memory 60 at the memory address supplied on lead 61 and, simultaneously, the pager operator visually receives the message "CALL YOUR OFFICE" .
  • a caller again requests the same page be transmitted to pager 20.
  • the entire storage procedure can be transparent to the caller. That is, the caller again identifies pager 20 by its specific address and inputs the alphanumeric information, "CALL YOUR OFFICE".
  • CPU 26 compares the alphanumeric information to information stored in memory 30 and detects a comparison.
  • CPU 26 then orders transmitter 18 to transmit only the address of pager 20 and the address at which the specific information is stored in memory 60.
  • calling numbers are processed to obtain meaningful source descriptions, which are then communicated to pager 20.
  • a set of pager-unique, special-interest source numbers and associated source labels (informative text strings) must be entered for each subscriber in the data base (memory 30) of terminal 15 and stored in memory 30 for use by CPU 26.
  • the source numbers might be, for example, complete telephone numbers such as those assigned to the subscriber's secretary, boss, wife, customers, etc., or the numbers might be partial line numbers indicating a generic class of source, such as calls originating "inside” a PBX as opposed to coming in from "outside”.
  • the source labels briefly describe the source ("SEC”, “BOSS”, "WIFE” etc.).
  • the identifying label of the special interest source is also sent the first time and stored in memory 60, as previously described.
  • pager 20 locates the previously stored descriptive source label associated with the received source tag digit or digits (address) and immediately displays the associated source label followed by the message from the caller (which may, or ma" not, also be prestored) . While one might question t ⁇ . value of source labels when the number of special interest sources is only four (as in this example) , the value of the source label becomes obvious as the number of sources increases (as in steady customers of a salesman or repairman) . For that reason, this invention sets no limit on the number of source tags and source labels which can be used with each subscriber.
  • the pager operator can notify paging terminal 15 and the information along with its address, or source tag, can be erased from memory 30. The address will then be available to CPU 26 for the storing of some other information and will be erased in memory 60 of pager 20 when paging terminal 15 sends the next message to be stored at that location.
  • Many pagers now include a simple transmitter which is capable of sending an acknowledge signal to the paging terminal upon receiving the page. When a stored message is no longer useful or accurate a simple code word, such as the address of the obsolete information, could accompany the acknowledge signal, which code word would signal the paging terminal to erase the stored message.
  • each addressed location in memory 60 can be sufficient to store the largest number of characters that can be produced by display 64.
  • each addressed location can be only one half the length of display 64 and two (or more) messages could be addressed in sequence by a single page.

Abstract

Sont décrits un système et un procédé de téléappel dans lesquels chacun des dispositifs de téléappel (20, 21, 22) renferme une mémoire rémanente effaçable (60) et le terminal de téléappel comporte une mémoire pour chaque abonné, qui contient certains messages ou numéros d'usage fréquent. La première fois qu'un message est transmis, la mémoire du dispositif de téléappel est également activée de sorte que le message est mémorisé à une adresse spécifique. Toute transmission ultérieure du même message s'effectue par la seule émission de l'adresse du message stocké dans la mémoire du dispositif de téléappel. Ce dernier affiche alors le message stocké. Le message mémorisé peut être modifié par simple notification au terminal d'envoyer un nouveau message. Le numéro d'appel peut également être traité pour informer l'abonné de la mémorisation d'informations supplémentaires.
