CROSS REFERENCE TO RELATED APPLICATIONS
FIELD OF THE INVENTION
The present application is a continuation in part of U.S. patent application Ser. No. 09/408,640 filed on Sep. 30, 1999, and incorporates the same herein in its entirety.
- BACKGROUND OF THE INVENTION
The present invention generally relates to the field of communication, and particularly to preliminary communication identification and messaging.
With the increase of marketers utilizing direct communications, such as telemarketers, devices capable of identifying an incoming communication to enable a user to determine whether to accept a communication have become increasingly more popular. Previous methods of identification rely on specific information embedded in the signal to display information related to that call. For example, in a traditional “caller id” method a second signal is embedded in the first signal to display where the call originated and the originating caller's number. In another method, the data must be embedded within the signal to display the relevant identification data. There are numerous problems with these methods. First, the signal does not actually identify the originating caller, rather the signal identifies the source. Therefore, a user receiving a call cannot be certain as to who is actually calling them. Second, additional information must be embedded in the signal to even provide this information. Therefore, it would be useful to provide a method for preliminary communication identification wherein an embedded signal is not needed to identify the originating user and the actual user is identified, not simply where the call originated.
Typically, in a system of communication between a remote source and a local host, a connection is established before the transmission of data. For example, a connection may be initiated by a remote source transmitting a signal. The signal is received by the host after which the remote source and the host determine a common mode of operation. Determining a common mode of operation may include the process known as handshaking and negotiating protocols. After determining a common mode of operation, both the remote source and the host send signals, thereby actively communicating from the host to the remote source. Even if an identification system is utilized, both systems are already in contact. It is at this point, once both the remote source and the local host are aware of the connection that the communication of data is begun so as to enable identification data to be displayed. The signal may include caller identification information such as the originating source of the call and number to enable a user to determine whether to accept the call. Utilizing this method, a caller determines whether to accept the call based upon additional information contained in the data that identifies only the source of the call, and not the actual caller. Furthermore, the host is in contact with the remote source before identification data has been utilized so as to indicate to the remote source the reception of the signal by the host.
- SUMMARY OF THE INVENTION
Additionally, technological advances have made possible the utilization of video images along with audio data for communication between two or more parties. Video conferencing equipment, video phones, and the like allow users to actually see the person as they communicate. The numerous benefits of these systems are readily apparent. However, as such systems become more common place, traditional methods of identification of the initiating party may prove inadequate. A user is unable to determine the actual identity of the initiating party without allowing the initiating party to know of the reception of the communication. Therefore, it may also prove useful to provide a system and method for preliminary communication identification wherein the signal is capable of being communicated without indicating to the remote source that the signal is being received.
The present invention is directed to an apparatus and method for preliminary communication identification. The apparatus for preliminary communication identification includes a receiver for receiving a signal from a remote source and a communicator for communicating the received signal. The communicator is capable of communicating the received signal without indicating reception of the received signal to the remote source. The signal may include an image of a second user utilizing the remote source so as to enable a first user utilizing the apparatus to view the remote second user.
The present invention is further directed to a method for preliminary communication identification, which includes receiving a signal by a host system from a remote source and communicating the signal by the host. The signal may communicated without indicating reception of the signal by the host to the remote source.
In an embodiment of the present invention, an apparatus and method may utilize the signal to preliminarily identify a communication. For example, instead of requiring the use of embedded data in a signal to display identification information, the actual signal may be communicated so a user may determine whether to accept the communication. In this way, a viewer may determine the actual content of a communication and not just the source of the communication. In another embodiment of the present invention, a standardized signal may be utilized for preliminary communication identification.

FIG. 9 is a block diagram of a method for using a caller ID window of the receiving telephone to display a brief text message.
Reference will now be made in detail to the presently preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings.
Referring generally now to FIGS. 1 through 8, exemplary embodiments of the present invention for preliminary communication identification will be discussed. Preliminary communication identification is generally achieved between a host system and a remote source. In an exemplary embodiment, the host system and a remote source may include a video phone, video conferencing system, information handling system, convergence system, set-top box, digital information appliance, communication device, etc. A signal communicated between the host and remote source may include digital and analog data in any combination or standard as may be utilized by a person of ordinary skill in the art. Communication between the host and remote source may be accomplished over a network, which may include a local area network (LAN), wide area network (WAN), Internet, Internet service provider (ISP), World Wide Web, telephone line, satellite such as a digital satellite system (DSS), wireless such as a personal communication system (PCS) or any other network or combination of networks capable of communication between two or more devices that may be apparent to a person of ordinary skill in the art. It is understood that the specific order, or hierarchy, disclosed is an example. Based upon design preferences, it is understood that the specific order, or hierarchy, can be rearranged while remaining within the scope of the present invention. The attached method claims present elements of the various steps in a sample order, and are not meant to be limited to the specific order or hierarchy presented.
Referring now to FIG. 1, a presently preferred embodiment of preliminary communication identification 100 is shown. A user utilizing a host system including a video conferencing interface may receive a call 102. In response to the received call, a representation of the caller, such as a video thumbnail of the caller, may be displayed on the host system 104. Some embodiments of the invention use the caller ID window (e.g., LCD display) of the receiving telephone to display a brief text message identifying the caller or the topic of the call.
While the representation is displayed, an equivalent of a “ring” signal on a conventional telephone system may be displayed, such as a “call-in-progress” status indicator, which may be sent to the remote source to indicate the status of the call 106. The user of the host system may then determine the identity of the remote source by utilizing an actual image of the source 108. The call recipient may elect to answer the call, in which case a two-way video conferencing session between the remote source and the user may begin 110. Alternatively, if the user elects not to answer the call 112, the calling party may be treated in a “call-not-answered” mode, such as continuing ring tones or forwarding to voice mail 114.
Referring now to FIGS. 2 through 7, exemplary methods of utilizing the present invention are shown. A variety of methods may be utilized to provide preliminary communication identification of a remote source before indicating reception of the signal by the host system. It is anticipated that by a person of ordinary skill in the art may utilize a variety of combinations and differing orders of steps in practicing the present invention and not depart from the spirit and scope thereof. The following embodiments are shown to describe examples as may be desirable in exemplary instances.
Referring now to FIG. 2, an exemplary embodiment of the present invention is shown. The method 200 of preliminary communication identification is initiated by the transmittal of a signal by a remote source 202. A host receives the signal 204 and communicates the signal 206. For example, this signal may be communicated as an image of the user in a video conferencing system, shown in a window of an information handling system, a screen overlay, etc. A user may then determine whether to respond to the signal 208. If the user decides not to respond to the signal, the signal may be routed to a messaging device 210, such as an answering machine, recording device, etc. Additionally, an automatic system may be employed wherein the signal is routed based upon the type of signal being sent, such as video, audio, etc. or any other data contained in the signal. If the user decides to begin interaction with the signal, the remote source and host may then determine a common mode of operation 212, such as by negotiating protocols and connection rates. At this point, the user is ready to interact with the remote source 214 through the host. In this example, the user may determine whether to initiate interaction before the remote source is aware that a connection has been established. Indication to the remote source by the host may be accomplished at different points in the connection process, depending on the requirements of the connection.
The present invention provides a variety of different methods of accomplishing preliminary communication identification before indicating to a remote source that the signal is being received. As shown in FIG. 3, an exemplary method of preliminary communication identification 300 may utilize a standardized signal from a remote source 302. After the host receives the standardized signal 304, the host may communicate the standardized signal 306 to a user. A standardized signal may include a signal that operates at a predetermined speed and/or protocol so as to enable communication without negotiating a connection. This way, the user may decide to respond to the signal 308, such as by viewing the contents of the signal. If the user decides not to respond to the signal, the signal may be routed to a messaging device 310. However, if the user decides to respond to the signal, the user may then decide whether to optimize the connection 312. For example, the standardized signal may not operate at the optimum settings at which the remote source may connect to the host. By optimizing the connection, the host and the remote source may interact in a maximized manner. After the remote source and the host determine a common mode of operation 314, the user may interact with the signal 315. By utilizing this example, the remote source is not aware that the signal is being received until after the user makes a determination of whether to accept the communication. This method may be preferable when various connection speeds and protocols may be utilized by a connection between a host and a remote source, such as over a modem connection.
Additionally, in some instances the signal itself may be utilized directly for preliminary communication identification. Referring now to FIG. 4, an exemplary method 400 for preliminary communication identification is shown wherein the communication is a video conferencing signal. A remote source initiates contact with a host 402 at which time, the remote host sends a signal containing video conferencing data 404. The host then communicates the signal without sending an acknowledging signal 406. In this way, a user may determine whether to accept the communication signal 408 without indicating to the remote source that the signal is being received. Furthermore, by using the actual video conferencing signal, a user may determine the actual identity of the user of the remote source, instead of just determining where it originated. In this example, if the user decides to accept the signal, the host may send a signal indicating the reception of the signal 410 so as to initiate communication between the parties 412.
Referring now to FIG. 5, yet another exemplary method 500 for preliminary communication identification is shown wherein a determination of a common mode of operation is not needed. It may be preferable to directly utilize data from a remote host for preliminary communication identification when there is no need to negotiate a connection between the host and a remote source. For example, such as when the remote source and the host are connected over the Internet, local area network (LAN), wide area network (WAN), etc. A remote source may initiate contact and send a signal 502. When the host system receives the signal, the signal is communicated 506 to a user without indicating to the remote source the reception of the signal. Therefore, a user may determine whether to accept the signal 508 and send a received signal 510 to begin communication between the host and the remote source 512. The user may alternately decide not to accept the signal wherein no reply is given to the remote source. In this way, a user may identify a remote source yet the remote source may not determine whether the signal was preliminarily communicated.
As shown in FIG. 6, in some instances, it may be necessary to first determine a common mode of operation before preliminary communication may be achieved. In this method 600, a signal is first transmitted from a remote source 602 and received by the host 604. The host and the remote source then determine a common mode of operation 606, which may include connection speeds, protocols, etc. After the common mode of operation is established, the host communicates the signal 608 without sending a response signal to the remote source. A user may then determine whether to respond to the signal 610 and initiate interaction with the remote source 612 or route the signal to a message device 614. In this embodiment, even though a connection has been established, the signal from the remote source may be first communicated to the user by a host before initiating full contact with the remote source. Therefore, even though a connection has been established, the host has not indicated to the remote user that the signal is being received. For example, in a video conferencing network, an example of which is shown in FIG. 1, a host and a remote source may first determine a common mode of operation, such as negotiating connection speeds, protocols, etc. Once the connection is established the signal from the remote source may be communicated to the user so the user may view the originator of the video conferencing session. If the user wishes to respond to the signal, the user may then return video data so the remote source may then view the user. However, a user may wish to route the signal to a messaging device so as to respond to the remote source at a later time. In this example, it is only after the user of the host system has determined to accept the communication, by viewing the user of the remote source, that answering data was sent to the remote source to indicate reception of the signal.
Referring now to FIG. 7, a block diagram of an exemplary network system capable of being utilized for video conferencing is shown. In this embodiment, a host 702 and remote source 704 communicate over a network 706. The network may include Internet, network service provider, local area network (LAN), wide area network (WAN), telephone, etc. Typically, a host suitable for being utilized for video conferencing will include an input device 708 and an output device 714 for communicating with the remote source 704. An input device 708 may include a video-input device 710 for transmitting video data and an audio input device 712 for transmitting audio data. An output device 714 may include a video display device 716 for displaying video data and an audio communication device 718 for communicating audio data received from the remote source 704. Similarly, a remote source 704 may include an input device 720 including video 722 and audio 724 input devices and an output device 726 including video 728 and audio 730 communication devices.
Referring now to FIG. 8, a block diagram of an exemplary information handling system 800 operable to employ the present invention is shown. In this embodiment, processor 802, system controller 812, cache 814, and data-path chip 818 are each coupled to host bus 810. Processor 802 is a microprocessor such as a 486-type chip, a Pentium®, Pentium II®, Pentium III® or other suitable microprocessor. Cache 814 provides high-speed local-memory data (in one embodiment, for example, 512 KB of data) for processor 802, and is controlled by system controller 812, which loads cache 814 with data that is expected to be used soon after the data is placed in cache 812 (i.e., in the near future). Main memory 816 is coupled between system controller 814 and data-path chip 818, and in one embodiment, provides random-access memory of between 16 MB and 128 MB of data. In one embodiment, main memory 816 is provided on SIMMS (Single In-line Memory Modules), while in another embodiment, main memory 816 is provided on DIMMs (Dual In-line Memory Modules), each of which plugs into suitable sockets provided on a motherboard holding many of the other components shown in FIG. 8. Main memory 816 includes standard DRAM (Dynamic Random-Access Memory), EDO (Extended Data Out) DRAM, SDRAM (Synchronous DRAM), or other suitable memory technology. System controller 812 controls PCI (Peripheral Component Interconnect) bus 820, a local bus for system 800 that provides a high-speed data path between processor 802 and various peripheral devices, such as video, disk, network, etc. System controller 812 to assist in routing data between main memory 816, host bus 810, and PCI bus 820 also controls data-path chip 818.
In one embodiment, PCI bus 820 provides a 32-bit-wide data path that runs at 33 MHZ. In another embodiment, PCI bus 820 provides a 64-bit-wide data path that runs at 33 MHZ.

In another embodiment, a television tuner 823 is included for viewing television signals. In yet another embodiment, I/O bridge 822 and graphics controller 827 are each integrated on the motherboard along with system controller 812, in order to avoid a board-connector-board signal-crossing interface and thus provide better speed and reliability. In the embodiment shown, graphics controller 827 is coupled to a video memory 828 (that includes memory such as DRAM, EDO DRAM, SDRAM, or VRAM (Video Random-Access Memory)), and drives VGA (Video Graphics Adaptor) port 829. VGA port 829 can connect to VGA-type or SVGA (Super VGA)-type displays. Other input/output (I/O) cards having a PCI interface can be plugged into PCI connectors 821.
In one embodiment, I/O bridge 822 is a chip that provides connection and control to one or more independent IDE connectors 824-825, to a USB (Universal Serial Bus) port 826, and to ISA (Industry Standard Architecture) bus 830. In this embodiment, IDE connector 824 provides connectivity for up to two standard IDE-type devices such as hard disk drives, CDROM (Compact Disk-Read-Only Memory) drives, DVD (Digital Video Disk) drives, or TBU (Tape-Backup Unit) devices. In one similar embodiment, two IDE connectors 824 are provided, and each provide the EIDE (Enhanced IDE) architecture. In the embodiment shown, SCSI (Small Computer System Interface) connector 825 provides connectivity for up to seven or fifteen SCSI-type devices (depending on the version of SCSI supported by the embodiment). In one embodiment, I/O bridge 822 provides ISA bus 830 having one or more ISA connectors 831 (in one embodiment, three connectors are provided). In one embodiment, ISA bus 1030 is coupled to I/O controller 852, which in turn provides connections to two serial ports 854 and 855, parallel port 856, and FDD (Floppy-Disk Drive) connector 857. In one embodiment, FDD connector 857 is connected to FDD 858 that receives removable media (floppy diskette) 859 on which are stored data and/or program code 860. In one such embodiment, program code 860 includes code that controls programmable system 800 to perform the method described below. In another such embodiment, serial port 854 is connectable to a computer network such as the Internet, and such network has program code 860 that controls programmable system 800 to perform the method described below. In one embodiment, ISA bus 830 is connected to buffer 832, which is connected to X bus 840, which provides connections to real-time clock 842, keyboard/mouse controller 844 and keyboard BIOS ROM (Basic Input/Output System Read-Only Memory) 1045, and to system BIOS ROM 846.
FIG. 8 shows one exemplary embodiment of the present invention, however other bus structures and memory arrangements are specifically contemplated.

FIG. 9 depicts embodiments of the invention using the caller ID window of the receiving telephone to display a brief text message identifying the caller or the topic of the call. A display means for use in this embodiment for the caller ID window may be an LCD display, a CRT screen, an active matrix display, or other like type of visual display device communicatively coupled to the telephone. An exemplary environment for embodiments of the invention is a network connection—e.g., a telephone voice link—via the public switched telecommunication network (PSTN) using protocols which include the Signaling System 7 (SS7) protocol. The invention may be practiced via wireless systems as well as PSTN landlines. Information concerning Caller ID, ISDN, SS7 and other communications protocols may be found in the text entitled “Digital Telephony” by John Bellamy (John Wiley & Sons, Inc., 1991), which is incorporated herein by reference in its entirety. In addition, U.S. Pat. No. 6,038,305 to McAllister, et al. and U.S. Pat. No. 5,490,251 to Clark, et al. generally involve aspects of Caller ID signaling and the PSTN, each of which is incorporated herein by reference in its entirety.
Referring to FIG. 9, an embodiment of preliminary communication identification 900 is shown. In step 901 a caller enters, and the system accepts entry of, a text message to be transmitted to a user in conjunction with an incoming call alert ring signal for the host system telephone. The message may be entered using the keypad of the caller's telephone, or using an alphanumeric keypad for entry of such messages connected to the caller's telephone line. The text message is sent in conjunction with signaling data for the incoming telephone call—for example, as a ring signal—wherein the incoming telephone call may be in the form of video conferencing data, digital data, and analog data. The text message may be transmitted in accordance with the SS7 protocol to the host system telephone. Typical with the SS7 protocol, the caller ID information (CID info) is transmitted using FSK modem tones sent in between the first and second telephone rings only. The text message entered by a user is sent in lieu of CID information between the first and second rings, and in some embodiments, in short block caller ID messaging format between the third and fourth rings and additional rings. That is, a variant of SS7 may be implemented to update the CID info between each ring, thus sending short blocks of a message (e.g., ten characters at a time), until the called party picks up the phone and goes off-hook to answer the call. The message may be repeated if it is sent in its entirety before the call recipient goes off-hook or otherwise acts on the message. A further variant of SS7 makes these features available to multi-line trunk calling systems, e.g., telemarketing call centers. In this embodiment, all callers from the trunk system—or alternatively, predefined subgroups of the trunk system callers—send the same message, e.g., a marketing message identifying the topic of the call to the called party.
In step 902 the telephone call is placed and the entered text message is sent in conjunction with a calling signal. The called party, that is, a user utilizing a host system telephone, receives a call at step 902. In response to the received call, a text message from the caller may be displayed on the host system 903. While the message is displayed, an equivalent of a “ring” signal on a conventional telephone system may be displayed, such as a “call-in-progress” status indicator, which may be sent to the remote source to indicate the status of the call. In step 904 the user of the host system—that is, the called party or call recipient—may then determine the topic of the call and/or the identity of the remote source by utilizing the transmitted text message from the caller. The call recipient may elect to answer the call in step 907, in which case a two-way telephone link, or a two-way video conferencing session, between the remote source and the user begins.
If, in step 904, the user elects not to answer the call, the calling party may be treated in a “call-not-answered” mode in step 905. Step 905 can entail the called party entering a predefined key from the keypad of their telephone to provide a predefined return message to the caller. The predefined return message may be a text message or a voice message which is recorded or computer generated. The recording or computer generation of the return message may take place before the call is received (several alternatives can be created), or while the call recipient is deciding whether to answer the incoming telephone call. The predefined return message may be a message such as: “please remove my name from your calling list;” “this phone line does not accept unsolicited telephone calls;” “you phone call has been rejected;” “please call back at a later time;” or other like type of return message. The return message may be transmitted back from the call recipient to the calling party without ever having the call recipient go off-hook. For example, the incoming call may come in when the call recipient is on the line with another call, and the call recipient can send a return message back to the calling party while the call recipient remains on the line with the other call. Whether or not a return message is provided back to the caller in step 905, the method proceeds to step 906 for either: 1) continuing ring tones; 2) go on-hook and hang-up; or 3) forwarding the incoming call to voicemail in step 906.
The text messages which may be sent in accordance with the embodiment depicted in FIG. 9 can include the caller's name or relationship to the called party. The text messages. The message is displayed between “rings” associated with the incoming telephone call. For example, the caller ID window can be used to display the message, “dad calling about the basketball game.” Some caller ID windows are limited to a predefined number of characters, for example, 10 alphanumeric characters. When using such devices, the caller would most likely provide an abbreviated message, preferably (but not required) in blocks of text no larger than the called party's caller ID window (e.g., 10 characters). For example, the above message—“dad calling about the basketball game”—could be sent in two blocks separated by incoming rings as: (ring) “dad callng” (ring) “re bb game” (ring). This translates to “dad calling regarding basketball game,” roughly the same message as above, except abbreviated to fit into two blocks of ten characters. The message may be most well received if it is sent in the form of a customized message associated with either the calling party (e.g., “dad”) or a topic proposed for conversation in the call (e.g., “basket ball game” or, as below, “sale $2999”).
For telemarketers or other unknown calling parties—that is, calling parties other than friends and family having a close personal relationship—the message preferably should tend to be more self explanatory. For example, a company may wish to use caller ID text messaging to send a brief sales message. Such a message is displayed in the LCD window, by providing additional words between each ring. For example: (ring) “Plasma tv” (ring) “sale $2999” (ring) “Gateway.” The short messages intended to fit within a caller ID display window (e.g., less than 10 characters long) is referred to herein as “short block caller ID messaging format.” In this way, the called party would be provided with some idea of the topic of the incoming call before answering the telephone. In this example, before answering the telephone the called party would most likely understand that the incoming call pertains to Gateway® Inc's sale of plasma televisions for the price of $2999. Such messages are very useful to companies engaged in telephone sales since, presumably, only interested called parties will answer the telephone call based on the content of the message.
In an alternative embodiment which supports the sending of longer text messages (e.g., 100 characters or more), the call recipient's telephone allows the call recipient to scroll back and forth through the message while remaining on-hook. To perform the scrolling, either a pair of standard phone pad keys are used (e.g., the * and # keys), or a pair of specialized arrow keys can be provided on the telephone handset or near the caller ID display. Alternatively, a telephone having a larger CID window can be used, thus eliminating the need to scroll back and forth, except for messages larger than the display window.
Although the invention has been described with a certain degree of particularity, it should be recognized that elements thereof may be altered by persons skilled in the art without departing from the spirit and scope of the invention. One of the embodiments of the invention can be implemented as sets of instructions resident in the main memory 816 of one or more information handling systems configured generally as described in FIG. 8. Until required by the information handling system, the set of instructions may be stored in another readable memory device. For example in a hard disk drive or in a removable memory such as an optical disk for utilization in a CD-ROM drive, a floppy disk for utilization in a floppy disk drive, a floptical disk for utilization in a floptical drive, or a personal computer memory card for utilization in a personal computer card slot. Further, the set of instructions can be stored in the memory of another information handling system and transmitted over a local area network or a wide area network, such as the Internet, when desired by the user. Additionally, the instructions may be transmitted over a network in the form of an applet that is interpreted or compiled after transmission to the computer system rather than prior to transmission. One skilled in the art would appreciate that the physical storage of the sets of instructions or applets physically changes the medium upon which it is stored electrically, magnetically, chemically, physically, optically or holographically so that the medium carries computer readable information.
It is believed that preliminary communication identification of the present invention and many of its attendant advantages will be understood by the forgoing description. It is also believed that it will be apparent that various changes may be made in the form, construction and arrangement of the components thereof without departing from the scope and spirit of the invention or without sacrificing all of its material advantages. The form herein before described being merely an explanatory embodiment thereof. It is the intention of the following claims to encompass and include such changes.
