## Title
Key word programmable caller ID

## Abstract

Methods and systems are disclosed for providing Key Word Programmable Caller ID Screening services. One method monitors a telephone call for a key word call screening request. The telephone call is from a calling telephone number to a called telephone number. An action is taken in response to the key word call screening request. The action could be playing an announcement, terminating the connection, forwarding to voice mail, storing, adding, updating, and or blocking incoming communications matching the ICLID information and/or subscriber identified alphanumeric information. The call screening request may comprise a Dual-Tone Multi-Frequency, a softkey entry, and/or a data message. Subsequent incoming calls from the calling telephone number are characterized as undesirable and are screened from alerting or otherwise establishing a communications connection to the called telephone number.

BACKGROUND
The exemplary embodiments relate to the field of telephony and of computers and, more particularly, to methods and systems for providing communications screening services.
Communications has experienced explosive growth, and more growth is planned as communication access and numerous communications devices improve. This explosive growth is revolutionizing special services offered to subscribing customers. Of the special service offerings, the most relevant to this invention is the caller identification or Caller ID services. A customer or a user of a telephone (or alternate communications device) that is served by the Caller ID service is provided with a calling party's directory information. Presently available Caller ID systems provide the calling party's telephone number and billing name associated with the calling party's telephone number (if available) when an incoming communication line identification (ICLID) signal can be detected, decoded, and transmitted to the called telephone or other display device associated with the called telephone (e.g., a Caller ID device). The Caller ID services also allow a receiving party to receive directory information for other incoming communications while the receiving party's phone is used (e.g., during a conversation with another party); this service is sometimes referred to as Caller ID communication Waiting service. A customer may use the Caller ID information to make a decision whether to answer and/or to prepare for the incoming communication.
In addition, the customer may use Caller ID information to block incoming communications associated with one or more ICLID signals including specific telephone numbers selected by the customer and/or privacy screening services for unidentifiable telephone numbers of incoming communications (e.g., telemarketers). If the customer wants to selectively answer incoming communications using Caller ID information, the customer has several choices—block the communication or ignore the ringing (or other communication handling system), or until the caller hangs up. If the communication is blocked, then the customer may not have immediate notification of the incoming blocked communication to re-evaluate whether to accept the communication since circumstances for accepting the communication may change. If the customer ignores the communication and listens to unwanted ringing, then the customer may be annoyed with the repetitive noise alerting the customer of the call. In recent years, telephony providers and manufacturers have tried to provide alternate systems and methods to alert the customer of selective incoming communications that minimizes interruptions for unwanted calls.
Companies and governments are trying to prevent or otherwise filter telemarketing calls. Nearly everyone has experienced an annoying telemarketing call, and every year many people are defrauded by telemarketers. Many products, such as the TELEZAPPERTM, attempt to reduce telemarketing calls (TELEZAPPER is a trademark of the Royal Appliance Manufacturing Company, www.royalappliance.com). The United States Federal Trade Commission and many state governments have created “Do Not Call” lists/registries that make it illegal for telemarketers to communication a phone number on the list.
Communications service providers also offer services that reduce telemarketing communications. BellSouth Corporation, for example, offers PRIVACY DIRECTOR® service (PRIVACY DIRECTOR® is a registered trademark of BellSouth Intellectual Property Corporation). This service tries to prevent unwanted calls, such as telemarketing calls, from ringing a subscriber's phone. This PRIVACY DIRECTOR® service does not connect a communication when the ICLID information is private. That is, the telecommunications switch recognizes when the ICLID information is marked private, so Caller ID cannot recognize the ICLID information. The PRIVACY DIRECTOR® service requires the calling party to i) unblock their telephone number or ii) announce their name. If the calling party unblocks their telephone number, then the ICLID information is delivered with the communication and the subscriber's Caller ID displays the number. If the calling party decides to announce their name, the telephone communication is routed to a media server. The media server plays an announcement that asks the calling party to record their name. The recorded name is delivered to the called party. The called party, prior to acceptance of the call, hears the recorded name of the calling party. The called party then has the option to accept the call. This PRIVACY DIRECTOR® service puts the called party in control as the recipient of the calls.
Now, however, telemarketers have learned to bypass the PRIVACY DIRECTOR service. For example, telemarketers have begun to use public communications addresses to get around the PRIVACY DIRECTOR service by unblocking their caller ID. The telemarketer's telephone number, then, is public as opposed to private. Because the telemarketer's telephone number is public, the PRIVACY DIRECTOR service does not prevent a connection to the called party. The Caller ID service displays the ICLID information, the subscriber answers the incoming communication, and the subscriber is then subjected to the telemarketer's unwanted proposal.
There is, accordingly, a need in the art for identifying and processing undesirable incoming communications. For example, consumers want a quick and convenient way of disposing of incoming telemarketing and/or unsolicited communications.
SUMMARY
The exemplary embodiments include methods, systems, computer programs, and/or computer program products for screening unsolicited communications, such as incoming calls from telemarketers, surveys, and/or other communications. According to some of the embodiments, a communications service provider (e.g., a telecommunications provider, a data communications provider such as America Online, a cable communications provider, and other communications providers) provides this privacy screening service. According to some of the exemplary embodiments, a key word programmable caller identification service (also referred to herein as “Key Word Programmable Caller ID Screening,” “Key Word Programmable Calling Party Screening,” or “Privacy Screening”) automatically identifies if an incoming communication is from a desirable caller, if the incoming communication is from an undesirable caller, or if service is unable to determine the communication is from a desirable caller.
According to some of the exemplary embodiments, if the communication is from a desirable caller, then the communication may be selectively processed. For example, key words associated with an incoming line identification (ICLID) signal may be matched with key words selected or otherwise identified, programmed, and associated by the subscriber to characterize the incoming call as desirable or undesirable. According to an exemplary embodiment, if the subscriber's surname is “Forsberg,” then the subscriber may associate “Forsberg” with a desirable subscribes such that each communication from a calling party's communications device matching “Forsberg” is automatically connected, processed, or prioritized for call handling. Further, the subscriber may enter a communications address having ICLID information unassociated with “Forsberg,” and subsequently program, reset, or define the communications address with a naming or key work convention that includes “Forsberg,” such as “Rowdy Forsberg” to identify a family member affectionately know as “Rowdy Forsberg,” and thereafter automatically connect, process, or prioritize incoming calls from this programmed family member's communication address. Similarly, if an incoming call from a calling party is associated with an undesirable caller, such as an incoming communication that has “Private” ICLID signal, the subscriber may use the Key Word Programmable Caller ID Screening Module to route this call to a Do Not Disturb announcement and thereafter terminate the call or provide alternative call handling options.
According to exemplary embodiments, if an incoming communication is from a desirable caller, then the communications device may produce a distinct notification (e.g., selected ring tone, audible alert, or other alert). If the communication is from an undesirable caller, then terminate the communication to the subscriber's communications device and route the undesirable communication to a voice messaging and/or do not call service. Or, if the desirability of the caller is unknown, then provide an alternate distinctive alert to the subscriber.
And, according to further exemplary embodiments, the Key Word Programmable Caller ID Screening service may prompt the subscriber (or alternatively receive a communication screening request) to enter or otherwise identify ICLID information associated with a desirable incoming communication or associated with an undesirable incoming communication. For example, the communications screening request may comprise a Dual-Tone Multi-Frequency key (e.g., “Touch Tones”) on a telephone keypad, a softkey entry on a communications device, and/or a data message from an Internet Protocol phone or client application. The communication screening request is accepted and sent to the intelligence controlling a communications switch coupled with the communications device. The intelligence controlling the communications switch interprets the communication screening request and determines what action is required. As an example, heretofore when a party depressed a touch-tone key during a communication, a tone was generated, yet the communications network my not have recognized that tone as requiring an action. This invention, however, implements an action in response to the communications screening request. For example, the action may include playing an announcement, terminating the connection, forwarding the incoming communication to voice mail, forwarding a party of an ongoing communication to a voice messaging system to interrupt and terminate the communication, storing a desirable ICLID signal to the Key Word Programmable Caller ID Screening profile of the subscriber, storing an undesirable ICLID signal to the Key Word Programmable Caller ID Screening profile of the subscriber, adding undesirable ICLID information to a Do Not Call list associated with the subscriber, and/or storing an undesirable ICLID signal in a subscriber's blocked communications list. The Do Not Call list, the subscriber's Key Word Programmable Caller ID Screening profile, and/or the subscriber's blocked communications list may include communications instructions for a called number (e.g., a communications address input by the subscriber or user) as well as include communications instructions for other registered communications addresses (e.g., other telephone numbers associated with the subscriber, an email address of the subscriber, and other communications addresses of the subscriber).
Other systems, methods, and/or computer program products according to the exemplary embodiments will be or become apparent to one with ordinary skill in the art upon review of the following drawings and detailed description. It is intended that all such additional systems, methods, and/or computer program products be included within this description, be within the scope of the claims, and be protected by the accompanying claims.

For example, a first device could be termed a second device, and, similarly, a second device could be termed a first device without departing from the teachings of the disclosure.
The exemplary embodiments include methods, systems, computer programs, and/or computer program products for providing Key Word Programmable Caller Identification screening services. According to some of the exemplary embodiments, a Key Word Programmable Caller ID Screening service allows a subscriber to selectively receive screened incoming communications or to send a Key Word Programmable Caller ID Screening query for ICLID information during an interactive communication (e.g., telephone conversation). The Key Word Programmable Caller ID Screening query may comprise a Dual-Tone Multi-Frequency key (e.g., “Touch Tones”) on a telephone keypad, a softkey entry on a communications device, and/or a data message from an Internet Protocol phone or client application. The Key Word Programmable Caller ID Screening query is accepted and sent to the intelligence controlling the communications switch (and/or communications network). The intelligence controlling the communications switch interprets the Key Word Programmable Caller ID Screening query and determines what action is required. As an example, heretofore when a party depressed a touch-tone key during a live telephone call, a tone was generated, yet the telecommunications network did not recognize that tone as requiring an action. This invention, however, implements an action in response to the Key Word Programmable Caller ID Screening query. The action could include interrupting the conversation, playing an announcement, terminating the connection, forwarding to voice mail, storing incoming line identification (ICLID) information of the communications signal in a Key Word Programmable Caller ID Screening database, adding the ICLID information to a Do Not Call list, updating a subscriber's profile with the ICLID information, and/or storing the ICLID information in a subscriber's blocked communications list. The Do Not Call list, the subscriber's profile, and/or the subscriber's blocked communications list may include communications instructions for the called number (i.e., the subscriber's communications address engaged in a conversation or receiving notification of an incoming communication) as well as include communications instructions for other registered communications addresses (e.g., other telephone numbers associated with the subscriber, an email address of the subscriber, and other communications addresses of the subscriber). According to some of the exemplary embodiments, the incoming communication may be initially filtered by examining key words (e.g., “INC”, “Private”, “Unknown”, and other subscriber identified or network identified key words) and matching key words to words in a subscriber's profile database to determine if the incoming communication is desirable or undesirable, and in some embodiments to further process the incoming communication (e.g., route to voicemail, connect to called party (subscriber's communications address), etc.).
FIGS. 1-3 depict possible operating environments for exemplary embodiments of this invention. A Key Word Programmable Caller ID Screening Module 20 includes computer programs, computer systems, and communications systems that initially screen a call according to a subscriber's screening profile as well as allow a subscriber, in real time during a live telephone call to take actions during the call. The Key Word Programmable Caller ID Screening Module 20, for example, allows the subscriber to hit a Dual-Tone Multi-Frequency key, a softkey, and/or data message to play an announcement to the other party. This announcement may be a recording that rejects the caller, and the Key Word Programmable Caller ID Screening Module 20 could then automatically terminate the telephone call. Because the announcement may be personalized, the wording and tone of the announcement can be tailored to the subscriber's personality (e.g., a “soft” rejection or a “hard” rejection). The call screening request could alternatively forward the call to voice mail, thus still allowing the calling party to leave a message. The Key Word Programmable Caller ID Screening Module 20, however, also offers the subscriber the ability to add selective key word information to associate with the ICLID (or other network associated communications address) signal of the incoming communication.
FIG. 1 is a block diagram showing the Key Word Programmable Caller ID Screening Module 20 residing in a computer system 22. The Key Word Programmable Caller ID Screening Module 20 operates within a system memory device. The Key Word Programmable Caller ID Screening Module 20, for example, is shown residing in a memory subsystem 24. The Key Word Programmable Caller ID Screening Module 20, however, could also reside in flash memory 26 or peripheral storage device 28. The computer system 22 also has one or more central processors 30 executing an operating system. The operating system, as is well known, has a set of instructions that control the internal functions of the computer system 22. A system bus 32 communicates signals, such as data signals, control signals, and address signals, between the central processor 30 and a system controller 34 (typically called a “Northbridge”). The system controller 34 provides a bridging function between the one or more central processors 30, a graphics subsystem 36, the memory subsystem 24, and a PCI (Peripheral Controller Interface) bus 38. The PCI bus 38 is controlled by a Peripheral Bus Controller 40. The Peripheral Bus Controller 40 (typically called a “Southbridge”) is an integrated circuit that serves as an input/output hub for various peripheral ports. These peripheral ports could include, for example, a keyboard port 42, a mouse port 44, a serial port 46 and/or a parallel port 48 for a video display unit, on or more external device ports 50, and networking ports 52 (such as SCSI or Ethernet). The Peripheral bus Controller 40 could also include an audio subsystem 54. Those of ordinary skill in the art understand that the program, processes, methods, and systems described in this patent are not limited to any particular computer system or computer hardware.
The central processor 30 is typically a microprocessor. Advanced Micro Devices, Inc. for example, manufactures a full line of ATHLON® microprocessors (ATHLON® is a trademark of Advanced Micro Devices, Inc., One AMD Place, P.O. Box 3453, Sunnyvale, Calif. 94088-3453, 408.732.2400, 800.538.8450, www.amd.com). The Intel Corporation also manufactures a family of X86 and P86 microprocessors (Intel Corporation, 2200 Mission College Blvd., Santa Cara, Calif. 95052-8119, 408.765.8080, www.intel.com). Other manufactures also offer microprocessors. Such other manufacturers include Motorola, Inc. (1301 East Algonquin Road, P.O. Box A3309 Schaumburg, Ill. 60196, www.Motorola.com), International Business Machines Corp. (New Orchard Road, Armonk, N.Y. 10504, (914 499-1900, www.ibm.com), and Transmeta Corp. (3940 Freedom Circle, Santa Clara, Calif. 95054, www.transmeta.com). Those skilled in the art further understand that the program, processes, methods, and systems described in this patent are not limited to any particular manufacturer's central processor.
An exemplary operating system is WINDOWS® (WINDOWS® is a registered trademark of Microsoft Corporation, One Microsoft Way, Redmond Wash. 98052-6399, 425.882.8080, www.Microsoft.com). Other operating system (UNIX® is a registered trademark of the Open Source Group, www. Opensource.org), the UNIX-based Linux operating system, WINDOWS NT®, and Mac® OS (Mac® is a registered Trademark of Apple Computer, Inc., 1 Infinite Loop, Cupertino, Calif. 95014, 408.996.1010, www.apple.com). Those of ordinary skill in the art again understand that the program, processes, methods, and systems described in this patent are not limited to any particular operating system.
The system memory device (shown as memory subsystem 24, flash memory 26, or peripheral storage device 28) may also contain an application program. The application program cooperates with the operating system and with a video display unit (via the serial port 46 and/or the parallel port 48) to provide a Graphical User Interface (GUI). The Graphical User Interface typically includes a combination of signals communicated along the keyboard port 42 and the mouse port 44. The Graphical User Interface provides a convenient visual and/or audible interface with a user of the computer system 22.
FIG. 2 is a schematic showing the Key Word Programmable Caller ID Screening Module 20 operating within an intelligently-controlled communications network 56. This communications network 56 further represents an operating environment for the Key Word Programmable Caller ID Screening Module 20. The communications network 56 includes a communications switch 60 that may includes Advanced Intelligent Network (AIN) componentry 64 controlling many features of the communications switch 60. The Advanced Intelligent Network (AIN) componentry 64 would include the Key Word Programmable Caller ID Screening Module 20 operating within the computer system (shown as reference numeral 22 in FIG. 1). The communications switch 60 and the Advanced Intelligent Network (AIN) componentry 64 may also interface with a data network 66. The signaling between the communications switch 60, the communications network 62 (e.g., Public Switched Telecommunications Network), the Advanced Intelligent Network 64, and the data network 66, however, is well understood in the art and will not be further described. If a reader desires a more detailed explanation, the reader is directed to U.S. Pat. No. 5,430,719 issued to Weisser (Jul. 4, 1995), with the “Summary of the Invention” and the “Detailed Description of the Preferred Embodiment” sections incorporated herein by reference. The reader is also directed to U.S. Pat. No. 5,917,817 issued to Dunn et al. (Jun. 29, 1999), with the “Summary of the Invention” and the “Detailed Description” sections incorporated herein by reference.
FIG. 3 is similar to FIG. 2, yet FIG. 3 illustrates an exemplary packet network architecture. This exemplary packet network represents an alternative operating environment for the Key Word Programmable Caller ID Screening Module 20. Here the communications switch 60 includes a packet-based “softswitch.” This softswitch uses software control to provide voice, data, and video services by dynamically changing its connection data rates and protocols types. An application server 68 interfaces with the softswitch via a packet protocol, such as Session Initiation Protocol (SIP). This application server 68 includes voice service protocols, triggers, and operations that allow the communications network 62 and the data network 66 to interoperate.
FIG. 4 is a schematic illustrating an exemplary embodiment of providing Key Word Programmable Caller ID Screening services upon receiving an incoming call or during telephone calls. Here the Key Word Programmable Caller ID Screening Module 20 may initially screen a call using information in the Key Word Programmable Caller ID Screening Module 20, such as, ICLID information identifying an alphanumeric directory listing associated with the incoming call, or alternatively, subscriber programmed alphanumeric key words, phrases, and/or symbols associated with the ICLID information. This alternative, subscriber programmed alphanumeric information may be displayed to the subscriber's communications device 72 or alternative Caller ID display device (not shown). For example, key words associated with an incoming line identification (ICLID) signal may be matched with key words selected or otherwise identified, programmed, and associated by the subscriber to characterize the incoming call as desirable or undesirable. According to an exemplary embodiment, if the subscriber's surname is “Forsberg,” then the subscriber may associate “Forsberg” with a desirable subscribes such that each communication form a calling party's communications device matching “Forsberg” is automatically connected, processed, or prioritized for call handling. Further, the subscriber may enter a communications address having ICLID information unassociated with “Forsberg,” and subsequently program, reset, or define the communications address with a naming or key work convention that includes “Forsberg,” such as “Rowdy Forsberg” to identify a family member affectionately know as “Rowdy Forsberg,” and thereafter automatically connect, process, or prioritize incoming calls from this programmed family member's communications address. However, if an incoming call from a calling party is associated with an undesirable caller, such as an incoming communication that has a “Private” ICLID signal, then the Key Word Programmable Caller ID Screening Module may be programmed to automatically route incoming calls having this matched key word to a Do Not Disturb announcement and thereafter terminate the call or provide alternative call handling options.
In addition, the Key Word Programmable Caller ID Screening Module 20 allows a subscriber, in real time during a live telephone call, to take actions during the call. If either party to the telephone call is a subscriber to this Key Word Programmable Caller ID Screening service, then the Key Word Programmable Caller ID Screening Module 20 allows the subscriber to utilize a key word call screening request during the actual telephone call. The key word call screening request may comprise a Dual-Tone Multi-Frequency tone on a telephone keypad, a softkey on a similar keypad, and/or a data message (e.g., an SIP message). As FIG. 4 shows, a telephone call is placed from a calling telephone number 70 (hence the calling party) to a called telephone number 72 (the called party). The telephone call is processed from the calling party (the incoming communications signal with the incoming line identification information 70), into the communications network 62, and to the destination communications switch 60 serving the called party (the called telephone number 72). The intelligence controlling the destination communications switch 60 detects a trigger that identifies either party as a subscriber to this Key Word Programmable Caller ID Screening service. The destination communications switch 60 is then instructed to establish a connection between the ICLID information and the called telephone number, thus allowing the parties to converse.
Once the connection is established, the live telephone call is monitored for the key word call screening request. The live telephone call is monitored for the next event, and that event is entry of the key word call screening request. The terms “monitor,” “monitoring,” and “monitored” mean the communications network 56 listens for, and/or is able to detect, a Dual-Tone Multi-Frequency tone signal, entry of a softkey, or receipt of a data message. The communications switch 60, for example, may listen for the Dual-Tone Multi-Frequency tone, or the communications switch 60 may be instructed to listen for the Dual-Tone Multi-Frequency tone. The terms “monitor,” “monitoring,” and “monitored” may also mean the Advanced Intelligent Network componentry 64, or the application server 68, listens for the Dual-Tone Multi-Frequency tone. The Advanced Intelligent Network componentry 64, or the application server 68, could instruct or command some portion of the communications network 56 to listen for the Dual-Tone Multi-Frequency tone. As those of ordinary skill in the art understand, Dual-Tone Multi-Frequency signaling is a means of transferring information from a party to the communications network 56 through the use of in-band audio tones. Each digit of information is assigned a simultaneous combination of one of a lower group of frequencies and one of a higher group of frequencies to represent each digit or character. The communications network 56 monitors the telephone call for the next event to happen-in this case, the next event is entry of a Dual-Tone Multi-Frequency tone. The Dual-Tone Multi-Frequency tone is accepted and sent to the intelligence controlling the communications switch 60 (such as the Advanced Intelligent Network componentry 64 or the application server 68) for interpretation and for an action.
Upon entry of a Dual-Tone Multi-Frequency tone, the communications network 56 takes an action. This invention allows the subscriber to utilize the touch-tone keys 74 on the telephone keypad 76 during the telephone call. Heretofore when a party depressed a touch-tone key 74 during a live telephone call, a tone was generated, yet the communications network 56 did not recognize that tone as requiring a key word call screening action. This invention, however, implements an action in response to the Dual-Tone Multi-Frequency tone. This invention, for example, launches a next event list and arms the T_DTMF_ENTERED event in the authorize termination message. This event could make the communications switch 60 listen in on the telephone call and wait for a DTMF event. When the subscriber presses any key 74 on the keypad 76, and hangs up, the Key Word Programmable Caller ID Screening Module 20 launches an event back to the Advanced Intelligent Network 64 (e.g., a Service Control Point). The Advanced Intelligent Network 64 checks the digit that was entered by the subscriber and takes the appropriate action. The action could include playing an announcement, terminating the connection, forwarding to voice mail, storing the ICLID information in a database, adding the ICLID information (or other line identification information) to a Do Not Call list, updating a subscriber's profile with selected alphanumeric portions of the ICLID information, and/or storing selected alphanumeric portions of the ICLID information in a subscriber's blocked communications list.
A call screening request, for example, could be used to reject incoming marketing communications such as solicitations. For example, when a subscriber receives a telemarketing call, the subscriber may, in real time during the live telephone call, enter the key word call screening request. The subscriber, for example, could hit a Dual-Tone Multi-Frequency key 74 on the keypad 76, hit a softkey on the keypad, or send a data message from a computer device. The communications network 56 recognizes that key word call screening request tone as requiring an action. Here, for example, that action might be playing an announcement 78 to the calling party. This announcement might be a network-based “telemarketing slam” that rejects the telemarketer. Once the announcement is played, the communications network 56 could also be instructed to terminate the connection between the calling party and the called telephone number. This method of rejecting telemarketing calls (i.e., playing the announcement and then terminating the call) would appeal to those subscriber's who desire a quick, convenient and, yet, polite method of disposing of telemarketers.
Another action might be voicemail. When a subscriber receives a telephone call, the subscriber may, in real time during the live telephone call, enter the key word call screening request. The subscriber, for example, could hit the Dual-Tone Multi-Frequency key 74 on the keypad 76, hit a softkey on the keypad, or send a data message from a computer device. The communications network 56 recognizes that call screening request as requiring an action. Here the action is forwarding the telephone call to voicemail. At any time during the telephone call the subscriber could forward the other party to voicemail. The other party would hear the subscriber's voicemail announcement. The other party to the telephone call could then record a voicemail message to a voicemail database (shown as reference numerals 78, 84 in FIG. 5), and the subscriber could retrieve this voicemail message at a later time. If, for example, a subscriber is intrigued by a telemarketing proposal, yet does not want to talk with the telemarketer, the subscriber could enter a Dual-Tone Multi-Frequency tone and forward the telemarketer to voicemail. The subscriber could then retrieve the voicemail message at a more convenient time.
This voicemail feature, however, is not only for telemarketing. This voicemail feature would also appeal to anyone requiring voicemail during a live telephone call. When, for example, a more important situation arises during the telephone call, the subscriber may forward the other party to voicemail, tend to the important situation, and later retrieve the voicemail message.
The announcement could be personalized. The subscriber could access the intelligence controlling the communications switch 60 and record a personalized announcement. The subscriber, for example, could access a media server using a toll-free administrative telephone number. The media server could utilize Caller ID to recognize the subscriber's home telephone number, or the media server could prompt for a subscribing telephone number. The media server steps the subscriber through a series of prompts and allows the subscriber to record the personalized announcement. The personalized announcement could be any greeting, message, or telemarketing rejection. The personalized announcement could be stored as a specific file in the media server. When the subscriber then enters a DTMF during a live telephone call, the communications switch 60 could then play the personalized announcement. The communications switch 60, instead, could be instructed to forward the telephone call to the media server for the personalized announcement. The subscriber might have a number of different personalized announcements, and the particular announcement depends upon which DTMF is entered. If the subscriber, for example, enters a “4” on the keypad 76, the communications switch 60 sends the telephone call to the intelligence (e.g., the AIN 64 or the application server 68). The intelligence recognizes that Dual-Tone Multi-Frequency tone as requiring action, and this action is playing the particular personalized announcement corresponding to the DTMF. The intelligence returns instructions to the communications switch 60 to forward that call to the media server. The media server accesses the particular personalized announcement corresponding to the called telephone number and the DTMF. The media server then plays the particular personalized announcement.
FIG. 5 is a schematic illustrating another exemplary embodiment for providing Key Word Programmable Caller ID Screening service during telephone calls. Here the action taken is storing the ICLID information as well as subscriber identified alphanumeric information (e.g., “Mom Home” to associate with the home phone number of the subscriber's mother) associated with the incoming marketing communication in a database. When the subscriber enters the call screening request, for example, the communications network 56 could add the ICLID information and/or the subscriber identified alphanumeric information to a Do Not Call list/database 80. This Do Not Call list/database 80 could contain one or more telephone numbers and/or other communications addresses (e.g., email address, IP address, and other communications addresses) of a subscriber that do not wish to receive telemarketing calls. As used herein, the term “subscriber” includes customers, consumers, and users of a communications device at a communications address (e.g., the called number, an email address, a cell phone number, etc.). Because the subscriber need only enter the call screening request to add/register a communications address (e.g., telephone number) to the Do Not Call list/database 80, the Key Word Programmable Caller ID Screening service provides a very quick and convenient method of preventing subsequent marketing communications. Further, the call screening request could also update other Do Not Call lists, such as wireless versions, wireline versions, electronic communications addresses, a spouse's version, a kid's version, and/or combined versions. When the call screening request is entered, the ICLID information and/or subscriber identified alphanumeric information of the incoming undesired communication could be forwarded to a remote database 82 via the data network 66. The remote database 82, for example, could be a government Do Not Call list. The ICLID information and/or subscriber identified alphanumeric information, for example, could be communicated to a subscriber's Do Not Call database 82, voicemail 84, or a governmental Do Not Call database 86 via the data network 66. The governmental Do Not Call database 86 could be provided by a state governmental agency (e.g., the state attorney general), a federal governmental agency (e.g., FCC), and others. The federal Do Not Call database 86 could be provided by a federal agency (e.g., the Federal Trade Commission). When the subscriber enters the call screening request, the communications network 56 could automatically add the ICLID information and/or subscriber identified alphanumeric information to various databases, thus further reducing unwanted telemarketing calls.
This Key Word Programmable Caller ID Screening service also helps the subscriber prove violations of Do Not Call lists and/or monitoring services. Some state and federal laws prohibit telemarketing calls to telephone numbers on these Do Not Call lists. Because the communications network 56 maintains a date and a time of any telephone call, the communications network 56 could “tag” each telemarketing call. When the subscriber enters the call screening request, and the communications network 56 adds/communicates the ICLID information and/or subscriber identified alphanumeric information to a Do Not Call list/database 80, the communication could also include the date and time of the undesired telephone call as well as other line identification information. When future telephone calls are received, the communications network 56 could query the Do Not Call list/database for the line identification information, ICLID information and/or subscriber identified alphanumeric information. If a match is found, the Key Word Programmable Caller ID Screening service could alert the subscriber and provide dates and times of the matching telephone numbers. The subscriber would then have evidence to pursue legal action against the telemarketer.
FIG. 6 is a schematic illustrating still another exemplary embodiment for providing Key Word Programmable Caller ID Screening service during telephone calls. When the subscriber sends the call screening request during a live telephone call, the communications network 56 recognizes that call screening request (such as a Dual-Tone Multi-Frequency tone) as requiring an action. Here the action comprises updating a subscriber's profile information 88 with the ICLID information and/or subscriber identified alphanumeric information of the incoming marketing communication. The subscriber's profile information 88 is stored in a database 90 of subscriber profiles. The database 90 of customer profiles may be maintained on the Advanced Intelligent Network 64 or the application server 68, or as FIGS. 6 and 7 show, a communications service server 92 communicates with the Advanced Intelligent Network 64 or the application server 68. The database 90 of customer profiles could also be maintained on a computer/server operating on the data network 66. As shown in FIGS. 5, 6, and 7, the customer profiles may include key words associated with allowing an incoming call to be connected, such as for incoming calls having alphanumeric ICLID and/or subscriber identified alphanumeric information matching the key words “Forsberg”, “Mom”, “Dad”, and/or “Boss”. Similarly, the customer profiles may include key words, such as, “Brother”, “Mobile”, “MGMT” and/or “INC” that trigger automatic routing of the incoming call to voicemail. And, the customer profiles may include key words, such as “*Dial”, “Private”, and/or “Unknown” that trigger automatic routing of the incoming call to the do not disturb call processing features.
According to an exemplary embodiment, the profile information 88 may be updated with the ICLID information and/or subscriber identified alphanumeric information. That is, when the subscriber enters the call screening request during a live telephone call, the action taken comprises storing the ICLID information and/or subscriber identified alphanumeric information in a subscriber's blocked communications list. The subscriber's blocked communications list contains calling telephone numbers (and other potential marketing communications addresses, such as an identifier of that the incoming call is from a cell phone in Florida) that the subscriber wishes to block or otherwise route to voice mail 94. When the communications switch 60 receives a subsequent telephone call, the intelligence controlling the switch 60 (the Advanced Intelligent Network 64 or the application server 68) suspends processing of the telephone call. A query is sent to determine if the ICLID information and/or subscriber identified alphanumeric information is found in the customer's profile information 88 and, hence, blocked from receipt. If the ICLID information and/or subscriber identified alphanumeric information is blocked, the caller is offered no additional opportunity to bypass the block. The ICLID information and/or subscriber identified alphanumeric information could also be added to related profiles, such as a spouse's profile, a child's profile, a wireless profile, and a wireline profile. Further, the profile information 88 may also include other associated subscriber communications addresses (e.g., a cell phone number, an identifier that the call is from a residential communications address, an identifier that the call is from a business address, an email address, and other communications addresses) that the subscriber wants to prevent subsequent communications from the calling party. That is, the undesired caller would be blocked from calling multiple communications addresses from the subscriber.
FIG. 7 is a schematic illustrating an exemplary embodiment for providing Key Word Programmable Caller ID Screening services to one or more other registered subscriber telecommunications addresses 102 and/or one or more other registered subscriber data communications addresses 112. These other registered communications addresses 102, 112 are stored with the profile information 88 in the database of customer profiles 90. When a subsequent incoming communication is placed from the calling party to one of the registered subscriber communications addresses 102, 112, the subsequent incoming communication to the registered subscriber communications address 102, 112 is also blocked from receipt (or alternatively, the incoming communication is processed according to the profile information, such as routing to voice mail 94, updating a government database, etc.). The registered telecommunications addresses 102 may include communications addresses for a cellular phone 104, another telephone 106, and another personal computer 108. Similarly, the registered data communications addresses 112 may include another cellular phone 114, another telephone 116, and another personal computer 118. Still further, these associated communications devices may also include a Voice over Internet Protocol (VoIP) phone and other communications devices.
As those of ordinary skill understand, the subscriber's profile information 88 relates to the subscriber's Key Word Programmable Caller ID Screening services. The specific information related to the provision, presence, and/or availability of these communication services is termed the “profile information” 88. This profile information 88 may include information related to the subscriber's calendar (e.g., appointments and activities), travel itinerary information, presence and availability information, other associated subscriber communications addresses, the subscriber's patterns of behavior, and most important to alphanumeric information that the subscriber associates with a calling party's communications address—the alphanumeric information may be a portion of the ICLID information or may otherwise be selected and identified by the subscriber and associated with the communications address. If the reader wishes to learn more about the profile information 88, and how the subscriber may view, add, delete, and otherwise define the subscriber's communications services and the profile information 88, the reader is referred to the commonly-assigned U.S. application Ser. No. 10/012,746, filed Dec. 7, 2001, and which the “Summary” and “Detailed Description” sections are incorporated herein by reference. The reader is also directed to the commonly assigned U.S. application Ser. No. 10/107,616, filed Mar. 27, 2002, and which the “Brief Summary of the Invention” and “Detailed Description of the Invention” sections are incorporated herein by reference.
The profile information 88 may also be accessed by the subscriber. The subscriber may use a computer system 94 to access the communications service server 92 via a connection to the communications switch 60 and a connection to the data network 66. The computer system 94 allows the subscriber to access the subscriber's profile information 88 and view/edit/delete information. Although the call screening request causes an automatic update of the blocked communications list, the subscriber could also access the profile information 88 and add telephone numbers to the list of blocked telephone numbers.
FIG. 8 is a flowchart showing a method of providing Key Word Programmable Caller ID Screening service. A telephone call is processed from a calling telephone number to a called telephone number (Block 800). The term “processing,” as used herein, encompasses every event from the time the ICLID information and/or subscriber identified alphanumeric information (shown as reference numeral 70 in FIGS. 4-7) goes off-hook to the termination of the telephone call. “Processing” of the telephone call includes routing a voice path and signaling setup and intelligence (e.g., Local Number Portability queries, queries to retrieve Calling Name/Number information, intelligence queries by the AIN 64 or the applications server 68, and standard signaling messages to determine call routing paths). The term “processing” also includes monitoring an established telephone call for possible Dual-Tone Multi-Frequency tone entry, switch hook flash, other events that indicate a party on the telephone call has requested an action, and delivery of call-waiting tones and data. “Processing,” however, also encompasses billing activities and measurements at the communications switch 60 or other communications network 56 element.
After a connection between the ICLID information and/or subscriber identified alphanumeric information and the called telephone number, the telephone call is monitored for an event (Block 802). Here, that event is entry of a call screening request, such as a Dual-Tone Multi-Frequency tone. Upon entry of the Dual-Tone Multi-Frequency tone, an action is taken in response to the Dual-Tone Multi-Frequency tone (Block 804). The action might comprise playing an announcement (Block 806), forwarding the telephone call to voice mail (Block 808), and updating a subscriber's profile with the ICLID information and/or subscriber identified alphanumeric information (Block 810). The action might also comprise storing the ICLID information and/or subscriber identified alphanumeric information in a database (Block 812), storing the ICLID information and/or subscriber identified alphanumeric information in the subscriber's blocked communications list for the called phone and for other associated communications addresses (Block 814), and/or communicating the ICLID information and/or subscriber identified alphanumeric information to a Do Not Call list (Block 816). The Do Not Call list could be maintained by a telecommunications service provider, a third party, a state government entity, and/or a federal government entity. The action could also comprise terminating the connection (Block 818).
FIG. 9 is a flowchart showing another method of providing Key Word Programmable Caller ID Screening service. A telephone call is detected, decoded, and deciphered in a communications network (Block 900). The telephone call is from a calling telephone number to a called telephone number. The ICLID or other incoming line identification information of the calling telephone number is compared with the subscriber profile to match screening fields. For example, if the incoming call is from a screened cellular phone in Canada matching the profile information, then the Key Word Programmable Caller ID Screening service may play an announcement (Block 904), take an action (Block 906), and terminate the connection (Block 930). If, however, the incoming call is not initially identified as an undesirable call, then the telephone call is connected to the called telephone number (Block 910). A call screening request, such as a Dual-Tone Multi-Frequency tone, is received from the called telephone number (Block 912), and an action is taken in response to the call screening request (Block 914). The action might comprise playing an announcement (Block 926), forwarding the telephone call to voice mail (Block 918), and updating a subscriber's profile with the ICLID information and/or subscriber identified alphanumeric information (Block 920). The action could also comprise storing the ICLID information and/or subscriber identified alphanumeric information in a database (Block 922), storing the ICLID information and/or subscriber identified alphanumeric information in a subscriber's blocked communications list for the called phone and for other associated communications addresses (Block 924), and communicating the ICLID information and/or subscriber identified alphanumeric to a Do Not Call list (Block 926). Thereafter, the connection with the incoming call may be terminated (Block 930).
FIGS. 10 and 11 are flowcharts showing other methods of providing Key Word Programmable Caller ID Screening service. A telephone call is processed from a calling telephone number to a called telephone number (Block 1002) or other associated, registered communications addresses (Block 1102). For example, the other associated, registered communications addresses may include other registered subscriber telecommunications addresses 102 (e.g., cellular phone, DSL, etc.) and/or one or more other registered subscriber data communications addresses 112 (e.g. email). After a connection between the ICLID information and/or subscriber identified alphanumeric information and the called telephone number, the telephone call is monitored for entry of a Dual-Tone Multi-Frequency (Blocks 1004, 1104). Upon entry of the Dual-Tone Multi-Frequency, an announcement is played (Block 1006, 1106). The announcement may be network-based (Block 1008, 1108) or a personalized prerecorded announcement of either party to the telephone call (Block 1010, 1110). The connection is then terminated (Block 1012, 1112).
According to some of the exemplary embodiments, the Key Word Programmable Caller ID Screening service may also be available after termination of the telephone call. After the subscriber hangs up the phone, the subscriber could still have an opportunity to screen the calling telephone. Assume the subscriber accepted the call and, after terminating the call, decides to block receipt of future calls from the same calling telephone number. The call screening request could also be recognized after termination of the call. The Key Word Programmable Caller ID Screening Module (shown as reference numeral 20 in FIGS. 1-7) could query the subscriber's profile information. The subscriber's profile information could contain a “last call received” data field. This “last call received” data field stores the ICLID information and/or subscriber identified alphanumeric information of the last received call. When the subscriber's telephone is offline, and then when the subscriber enters a predetermined call screening request, this call screening request instructs the Key Word Programmable Caller ID Screening Module (or some other application) to add the ICLID information and/or subscriber identified alphanumeric information of the last received call to the customer's profile. The “last call received” data field could even be temporary and change after each incoming call to avoid maintaining a long list of previously received calls. The subscriber could, for example, enter a Dual Tone Multi-Frequency tone to add the last received calling telephone number to the subscriber's profile. The subscriber could then, after termination of the call, add the ICLID information and/or subscriber identified alphanumeric information to the Do Not Call list or blocked communications list.
The Key Word Programmable Caller ID Screening Module (shown as reference numeral 20 in FIGS. 1-7) may be physically embodied on or in a computer-readable medium. This computer-readable medium may include CD-ROM, DVD, tape, cassette, floppy disk, memory card, and large-capacity disk (such as IOMEGA®, ZIP®, and other large-capacity memory products (IOMEGA®, ZIP®, and JAZZ® are registered trademarks of Iomega Corporation, 1821 W. Iomega Way, Roy, Utah 84067, 801.332.1000, www.iomega.com). This computer-readable medium, or media, could be distributed to end-users, licensees, and assignees. These types of computer-readable, media, and other types not mention here but considered within the scope of the present invention, allow the Key Word Programmable Caller ID Screening Module to be easily disseminated. A computer program product for providing Key Word Programmable Caller ID Screening during a telephone call comprises the computer-readable medium and the Key Word Programmable Caller ID Screening Module. The Key Word Programmable Caller ID Screening Module is stored on the computer-readable medium.
The Key Word Programmable Caller ID Screening Module (shown as reference numeral 20 in FIGS. 1-7) may be physically embodied on or in any addressable (e.g., HTTP, I.E.E.E. 802.11, Wireless Application Protocol (WAP)) wireless device capable of presenting an IP address. Examples could include a computer, a wireless personal digital assistant (PDA), an Internet Protocol mobile phone, or a wireless pager.
While this invention has been described with respect to various features, aspects, and embodiments, those skilled and unskilled in the art will recognize this invention is not so limited. Other variations, modifications, and alternative embodiments may be made without departing from the spirit and scope of this invention.
