  • the present invention relates generally to information transfer apparatus and methods, and more particularly to a method and apparatus for enabling telephonic transmission of data and other information transfer between a dial up host device and an initially offline remote device.
  • the communication infrastructure generally includes a plurality of servers and a plurality of routers. All of the routers are interconnected to and/or through each other to form a network over which the data may be transmitted.
  • the servers are also connected to this network and store the digitized information at addressable locations, this system of interconnected servers and routers is typically referred to as the Internet, the World Wide Web (WWW), and the Information Superhighway.
  • WWW World Wide Web
  • An individual, or internet user may typically access the internet through a subscription service with an internet service provider (ISP) which maintains a host device.
  • ISP internet service provider
  • the user in turn telephonicallv connects to the host device through a diaiup connection from a remote device, typically a personal computer.
  • a remote device typically a personal computer.
  • the user can access data located at any server by simply entering the Universal Resource Locator (URL), or address, of such data.
  • the data located at the server identified by the URL is retrieved and transmitted through the routers back to the host device of the user who has requested the URL.
  • the host device caches the data and retransmits it to the user ' s remote device where it may then be viewed, stored or printed.
  • public domain data located on any server anywhere in the world is generally instantaneously available to any such user or individual simply by connecting to a host device and entering the URL of the desired data.
  • the user can even establish a scheduling routine at the ISP or with another service connected to the WWW in which a specific URL is periodically checked and monitored for updates. If such updates exist, the scheduling routine retrieves the data and has it forwarded to the user ' s ISP where it is cached. To retrieve the information, the user must log on to the ISP to check for the presence of new information or data cached at the ISP for such user. If such new data is available, the user may then download the data from the host. Typically, the user has no prior knowledge whether such data is in fact available at the time of logging on to the ISP host. Thus, the user may only infrequently check for such updates burdening the host with the storing of the data.
  • the data may be frequently updated in the intervals between access by the user requiring the ISP to store even greater amounts of updated data in the forms of several generations of updates. It can then be readily seen and appreciated by those skilled in the art that as the volume of users subscribing to such services increases, the host becomes unacceptably burdened with establishing ever increasing amounts of memory capacity to store such user data awaiting download to all such user ' s remote devices
  • the message when so placed now contains a header or address portion identifying the POP server to which it is to be routed, the identity of the host device associated with such POP server, and the subscriber to such ISP for whom the message is intended.
  • the ISP for the recipient is now burdened with the storage of this, and a vast quantity of other, email messages awaiting retrieval by their intended recipients.
  • internet telephone Another type of data communication between remote devices involves a technology known as internet telephone.
  • internet telephony Although the present usage for internet telephony is presently minimal in comparison to other uses of the internet, interest and demand for internet telephony are rapidly increasing due to the fact that internet telephony allows a user to connect to any other user located anywhere in the world, and then exchange in real time voice coded data with such user. As the data is encoded and decoded at each users remote device, real time conversation becomes possible.
  • internet telephony requires enabling software in each remote device to encode speech into data for transmission and decode received data into speech.
  • the telephony software interacts with the remote device sound card and web browser software so that the computer's speakers and microphones act as a telephone set.
  • the originator of the telephone call need only make a local call to the ISP's diaiup host to connect to an IP address anywhere on the World Wide Web.
  • the originator beneficially avoids long distance tariffs and tolls which would have been incurred had the call been placed through the telephone service provider and telephone switches.
  • a disadvantage of limitation of internet telephony is that each remote device must be connected to their respective ISP host device prior to the internet call being placed. Thus, the originator and the recipient of the internet telephone call must pre-arrange a connection time between their respective remote devices.
  • Known internet telephony does not use any type of signaling to the recipient remote device
  • interface hardware to interconnect the remote device and the telephone set.
  • the originator of the call establishes a conventional telephone connection through the originator's interface device to the intended recipient.
  • the receiving interface device detects that the telephone connection is not a standard voice call but has originated from another identical interface device.
  • the recipient's interface device launches the appropriate software within the recipient's computer to initialize the computer for receipt of an internet call.
  • one disadvantage and limitation of the above described interface device is that requires the user to establish first a conventional telephone call and bear the burden of incurring charges for such telephone call.
  • Another disadvantage and limitation of the above described interface device is that it requires both the originator and recipient to purchase identical hardware in addition to the computer in telephone set.
  • a host device may be any computer or data processing system established to provide information services to distributed users such as an ISP or other internet or intranet, public or private, hubs.
  • a remote device is a data recording or reception device such as a personal computer or other data client not collocated with the host device. The remote device is offline if it does not have a data connection with the host device.
  • An online device has a data connection to the host device that may be a telephone line, a satellite link, a direct wire link or any conventional equivalent suitable for transferring any manner of digital data.
  • a telephone line as used herein may be any conventional technology from a twisted pair of copper wires to a fiber optic strand or a satellite data link.
  • the host device When the host device receives data intended for a remote device, the host device checks to determine if the remote device is currently online. If the remote device is online, it is notified that the data is available, or the data may be automatically downloaded to the remote device. As used herein, a download is a data transfer from the host to the remote device. If the remote device is not online, the host device may send a signal to the offline remote device to cause the remote device to establish an online data connection to the host device. The host device may use a coded ring signal or set of rings, such as ring once and hang up. to initiate the data connection. The host device may also use a coded signal similar to the caller ID signal or any other suitable conventional technique to initiate the data connection.
  • each of these techniques is the host device does not incur a chargeable telephone call to the remote device, yet the remote device is signaled to come on line.
  • a caller ID type of coded signal may also be sent to the remote device to initiate the data transfer connection. Using caller ID. the originator ' s telephone number is identified during signaling, and before any telephone connection is made, thereby obviating connect charges. The remote device may then initiate a call back to the identified caller ID.
  • the remote device would then call the host back at the user ' s expense, if any. to collect the user ' s data.
  • This signal from the host could be decoded by a device continuously monitoring the telephone lines without completing the telephone connection at the remote device and thus avoid creating a chargeable phone call for the host device or whoever initiated the call.
  • This technique does not necessarily require the receiving station to avoid answering the telephone on the first ring because the coded signal could be sent and received before the receiving telephone could ring.
  • a coded signal could also allow an almost unlimited number of hosts, each with a distinct code, to remotely initiate connections with remote devices.
  • the present invention provides a signal decoder at the remote device for decoding signals from the host device.
  • the decoder may be any conventional device suitable for distinguishing the signal from the host device and initiating a return telephone call from the remote device to the host device on receipt of the appropriate signal.
  • the signal decoder may be included in a modem for connecting a remote device to a telephone line.
  • the present invention may include software for the remote device that allows the remote device to establish an online data connection and to initiate data transfer from the host to the remote device.
  • the software may give the remote device the ability to upload stored data, such as outgoing e-mail, to the host device during a single telephone call initiated to download data from the host.
  • upload is a data transfer from the remote device to the host device.
  • the software would terminate the data connection as soon as the data transfer was complete between the host device to the remote device.
  • the present invention provides software for the host device that allows the host device to identifv which remote device has data to be downloaded and to send the appropriate signal to the appropriate remote device to initiate a return call from the remote device and subsequent data transfer.
  • a still further aspect of the present invention includes a method of initiating a data download to an offline remote device, receiving data at a host intended for a remote device, determining if the remote device is online with the host, sending the data to the remote device if the remote device is online. If the remote device is offline, sending a signal from the host to the remote device to cause the remote device to initiate a procedure to establish an online connection to the host device, transferring the data from the host device to the remote device when the remote is online, and terminating the online connection to the host device at the completion of the data transfer.
  • the method of initiating a data download to an offline remote device further comprises the step of uploading data from the remote device to the host device after the host device has completed downloading data to the remote device but before the remote device terminates the online connection to the host device.
  • An advantage of the present invention is that the host device by signaling the remote device allows the remote device to initiate connection to the host device for receipt of data that the host device would otherwise need to store until the user desired to retrieve such data.

  • Host device 50 may use modem 32 to dial the telephone number of remote device 12.
  • coder 42 controls communication line 31 to allow a predetermined ring signal, for example, only one ring and a hang-up. The single ring and hang-up operates as a call home signal 45 to decoder 18 that data is waiting at host device 50. Since each ring signal is followed by a fixed silent time prior to the next ring signal, the lapse of this time without a subsequent ring signal is decoded as a hang up by decoder 18.
  • Decoder 18 is configured to monitor communication line 13 for the predetermined ring signal, but not to pick-up the line.
  • Signal 45 may be sent from host device 50 to decoder 18 without cost for use of communication system 30 because decoder 18 doesn't answer the ring signal. Receipt and decoding of signal 45 by decoder 18 initiates data retrieval sequence 25 shown in Fig. 3.
  • Data retrieval sequence 25 may be any conventional means of initiating and following a series of preplanned steps.
  • Decoder 18 generates a start signal such as start signal 19 as shown at step 29.
