## Title
Adaptive call monitoring

## Abstract

A method of and system for filtering telephone calls receives a call to a called party from a caller and determines if the called party has an event scheduled. If the called party has an event scheduled, the system determines if the caller is associated with the event. The system completes the call if the caller is associated with the event. The system sends the call to voice mail if the caller is not associated with said event unless the caller is on an exception list associated with the event, in which case the system completes the call. The system completes the call if it is determined that said called party does not have an event scheduled.

## Background
FIELD OF THE INVENTION
The present invention relates generally to the field of telephone call processing, and more particularly to a method of and system for adaptive call filtering based upon availability information for the called party and the identity of the caller.
BACKGROUND OF THE INVENTION
Currently, there are few options for filtering phone calls other than programming an extension to ring at a specific place according to a specific schedule or manual selection. These options treat all callers in the same way. There is no simple way to direct calls differently depending upon who the caller is.
One known solution to the problem involves using a call direction system, such as AccesslineTM to control where or whether a called party's phone rings at a specific time. However, this call direction has to be set up in advance, either through a schedule or by logging in to a system and directing calls on the fly. Call direction is easy if the called party has access to the Internet and enough time to plan accordingly. However, this solution is not practical if the called party is caught in traffic or on the way to a meeting. Furthermore, the called party could be driving to the meeting, having diverted calls to voice mail, when an invitee to the meeting are other important person is trying to reach the called party to cancel the meeting or provide important information.
Another known solution involves systems that can detect a caller ID and statically direct a missed call to a predefined mailbox based on that caller ID. These systems are limited to categorizing voicemail to a predefined mailbox, and none of the systems allow a call to be dynamically routed based on criteria from the called party's calendar or from any other similar input. Current systems have to be programmatically changed and the programming last indefinitely until the next programmatic change.
SUMMARY OF THE INVENTION
Embodiments of the present invention provide methods of and systems for filtering telephone calls. A system receives a call from a caller to a called party and determines if the called party has an event scheduled. If the system determines that the called party has an event scheduled, the system determines if the caller is associated with the event. The system completes the call if the caller is associated with the event. The system sends the call to voice mail if the caller is not associated with said event unless the caller is on an exception list associated with the event, in which case the system completes the call. The system completes the call if it is determined that said called party does not have an event scheduled.
A system may determine if the called party has an event scheduled by accessing a calendar for said called party. In certain embodiments of the present invention, the system may determine if the caller is associated with the event from contextual information, such as the subject of the event, in the calendar entry for the event. The system may then access an address book or contacts list for the called party and determine whether to caller is associated with the context of the event. In other embodiments, the calendar entry for the event may include explicit phone settings that specify how to handle calls.

Call manager 103 is programmed according to the present invention to direct calls. Call manager 103 is coupled to a public switched telephone network (PSTN) 105. Call manager 13 may also be coupled to an Internet protocol (IP) network, such as the Internet, 107 through a voice over IP (VoIP) gateway 109. Call manager 103 is also coupled to a voicemail system 111.
System 101 also includes an e-mail/calendar server 113 and an instant message server 115. E-mail/calendar server 113 and instant message server 115 are coupled to call manager 103 through a network 117.
System 101 includes a plurality of the sets of user devices 119. A set 119 may include a personal computer 121, a telephone 123, and a mobile phone 125. Personal computer 121 may be a desktop workstation, a laptop computer, a personal digital assistant (PDA), or the like. Each personal computer 121 is coupled to network 117. Telephones 123 and mobile phones 125 are coupled to call manager 103. Those skilled in the art will recognize that wireless telephone infrastructure is omitted from FIG. 1 for purposes of simplicity of illustration.
As will be explained in detail hereinafter, when call manager 103 receives a call, either from outside system 101 from PSTN 105 or IP network 107, and within system 101 from a telephone 123 or mobile phone 125, call manager 103 may access e-mail/calendar server 113 and/or instant message server 115 to determine how to handle the call. In embodiments of the present invention, call filtering information may be stored in e-mail/calendar server 113 and/or instant message server 115. E-mail/calendar server 113 contains electronic calendar and address book information for users of system 101.
Referring to FIG. 2, there is illustrated a calendar entry 201 for a user of system 101. Calendar entry 201 includes a date field, a time field 205, an event field 207, a subject field 209, and a list of invitees 211. calendar entry 201 thus identifies a meeting scheduled for Jul. 7, 2007, from 12:30 to 13:30. The subject of the meeting is ABC, Inc. The invitees to the meeting are Evans, E., Finn, F., as and Stevens, S.
Referring to FIG. 3, there is illustrated a prescient of an address book for a user, designated by the numeral 301. Address book 301 includes fields that identify contacts and contact information. In address book 301 there is a name field 303, an office phone field 305, a mobile phone field 307, a home phone field 309, a company field 311, and accounts field 313, and the categories field 315.
FIG. 4 illustrates a meeting notice or scheduling dialogue 401. Scheduling dialogue 401 includes a subject field 403 into which may be entered the subject of a proposed meeting. A “When” area 405 contains fields into which the date and time of the proposed meeting may be entered. An “Invitees” area 407 includes fields into which the required, optional, and information invitees to the proposed meeting may be entered. Scheduling dialogue 401 includes a “Chair” field 409, which identifies the chair of the meeting. A “Where” field 411 includes fields into which location and resource information may be entered. Finally, a “Phone Settings” area contains radio buttons and checkboxes that allow a user to set up telephone filters for the meeting according to the present invention. In Phone Settings field 413, the setting is “Public,” which allows all phone calls to bring through during the meeting. When the chair sends meeting notice 401 or an invitee accepts the meeting notice 401, the meeting information, including the phone settings, is entered into the electronic calendar for the chair or invitee.
FIG. 5 illustrates a scheduling dialogue 501. Scheduling dialogue 501 differs from scheduling dialogue 401 in that in Phone Settings area 503, the “Private” radio button is selected and exceptions check boxes Family and Upline are checked. According to the embodiment of FIG. 5, Private phone settings allow phone calls only from callers invited to the meeting. Exceptions allow calls from identified individuals other than invitees to the meeting to be completed.
FIG. 6 illustrates a scheduling dialogue 601. Scheduling dialogue 601 differs from scheduling dialogue 501 in that in Phone Settings area 603, the custom radio button is selected. Custom phone settings 603 enable a user to filter calls to the meeting with a high degree of granularity.
FIG. 7 is a high-level flowchart of processing according to the present invention. In embodiments of the present invention, processing according to FIG. 7 may be performed by call manager 103 (FIG. 1). FIG. 7 processing may also be performed in an intelligent mobile phone that has a calendar.
Referring to FIG. 7, a call is received, as indicated at block 701. The call manager accesses the electronic calendar of the called party, as indicated at block 703. The call manager then determines, as indicated at decision block 705, if an event is scheduled at the current time. If not, the call manager determines, as indicated at decision block 707, if instant message (IM) status processing is set. IM status processing according to present invention provides a second layer of call filtration. If IM status processing is set, then the call manager performs IM status process, as indicated generally at block 708 and described in detail with reference to FIG. 12. If IM status processing is not set, the call manager completes the call, at block 710, and processing ends.
Returning to decision block 705, if an event scheduled at the current time, then the call manager determines, as indicated at decision block 709, if the caller is identified. As is known to those skilled in the art, a caller may be identified in a Signaling System 7 (SS7) initial address message (IAM), or according to other call signaling protocols. If the caller is not identified, then the call manager performs unidentified caller processing, as indicated generally at block 711 and illustrated in detail in FIG. 8. If the caller is identified, then the call manager performs identified caller processing, as indicated generally at block 713, details of which are illustrated with reference to FIG. 9 or 10.
Unidentified caller processing is illustrated in FIG. 8. The call manager prompts the caller to speak his or her name and waits for a response, at block 801. In alternative embodiments, the call manager may prompt the caller to enter his or her telephone number using a telephone key pad. If, as determined at decision block 803, the caller does not respond within a preset time limit, the call is sent to voice mail as indicated at block 805. In an embodiment of the present invention in which the caller is prompted to enter digits, processing may return to block 713 of FIG. 7. If, as determined at decision block 803, a response is received within the time limit, the call manager sends a message to the called party with the caller's name and waits for a response, as indicated at block 807. If, as determined at decision block 809, a response is not received from the called party within a preset response time, then the call is sent to voice mail at block 805. If, as determined at decision block 811, the called party accepts the call, the call manager completes the call, as indicated at block 813.
FIG. 9 illustrates one embodiment of identified caller processing according to the present invention. The call manager may optionally send an instant message advising the called party that a call has been received and asking for instructions for handling the call. Accordingly, the call manager sends an instant message to the called party with the caller's identity and waits for a response, as indicated at block 901. If, as determined at decision block 903, the called party does not respond within a preset time limit, the call manager accesses the address book of the called party, as indicated at block 905. If the called party does respond to the instant message, the call manager determines at decision block 907 if the called party's response is to accept the call. If so, the call manager completes the call, as indicated at block 909, and processing ends. If the called party does not accept the call, the call manager determines at decision block 911 if the called party's response is to forward the call to another number. If so, the call manager forwards the call to that number and processing ends at block 913. If the called party's response is not to forward the call, the call manager sends the call to voice mail and processing ends at block 915.
Returning to block 905, after the call manager has accessed the address book of the called party, the call manager determines if the caller is in the address book, at decision block 917. If not, the call manager sends the call to voice mail, as indicated at block 923, and processing ends. If the caller is in the address book, the call manager determines, at decision block 919, if the caller is associated with the subject of the meeting. If not, the call manager determines, at decision block 921, if the caller is on an exception list. If not, the call manager sends the call to voice mail, as indicated at block 923, and processing ends. If, as determined at decision block 919, the caller is associated with the subject of the meeting, or, as determined at decision block 921, the caller is on an exception list, the call manager determines, at decision block 925, if instant message status processing is set. If instant message status processing is not set, the call manager completes the call, as indicated at block 927, and processing ends. If instant message status processing is set, the call manager performs instant message status processing, as indicated generally at block 929 and described in detail with respect to FIG. 12.
If, as determined at decision block 919, the caller is not associated with the subject of the meeting, the call manager determines, at decision block 921 if the caller is on an exception list. In the embodiment of FIG. 9, an exception list is a list of callers from whom the called party will always take calls. If the caller is on an exception list, then processing continues at decision block 925. If the caller is not on an exception list, then the call manager sends the call to voice mail, at block 923.
FIG. 10 is a flow chart of an alternative embodiment of identified caller processing according to the present invention. The call manager determines, at decision block 1001, if phone settings are selected for the event. If not, the call manager determines at decision block 1003 if IM status processing is set. If not, the call manager completes the call, as indicated at block 1005. If instant message status processing is set, then the call manager performs instant message status processing, as indicated at block 1007.
Returning to decision block 1001, if phone settings are selected for the event, then the call manager determines, at decision block 1009 if the phone settings are public. A public phone setting means that all calls will be accepted. If so, processing continues at decision block 1003. If not, the call manager determines at decision block 1011 if phone settings for the event are set to private. As shown in FIG. 5, private phone settings allow calls to be received from invitees to the event and designated exceptions. If the phone setting is private, then the call manager determines, at decision block 1013 if the caller is invited. If so, processing continues at decision block 1003. If not, the call manager determines, at decision block 1015 if the caller is an exception. If not, the call manager sends the call to voice mail, as indicated at block 1017. If, as determined at decision block 1015, the caller is an exception, then the call manager completes the call, as indicated at block 1005. Returning to decision block and 11, if the phone setting is not private, then, by default, a phone setting is custom and the call manager performs custom processing, as indicated generally at block 1019.
FIG. 11 is a flow chart of custom phone setting processing according to an embodiment of the present invention. Custom phone settings are illustrated in area 603 FIG. 6. The call manager determines, at decision block 1101, if the caller is a “to” recipient of the event notification. It will be recalled that a recipient is a required attendee of the event. If so, the call manager determines, at decision block 1103 if the phone setting is ring. If so, the call manager sends a ring signal to the called party, as indicated at block 1105. If, as determined at decision block 1103, a phone setting is not ring, the call manager determines, at decision block 1107 if the phone settings vibrate. The vibrate setting is most applicable in the mobile phone environment. However, more generally, the vibrate setting may be interpreted as a non-audible signal. If the phone setting is vibrate, then the call manager sends a vibrate signal to the called party, as indicated at block 1109. If the phone setting is not vibrate, then the call manager determines, at decision block 1111 if a phone setting his voice mail. If so, the call manager sends the call to voice mail, as indicated at block 1113. If, as determined at decision block 1111, the setting is not voice mail, then the call manager ignores the call, as indicated at block 1115. The call manager may ignore a call by simply allowing a ring tone to continue on the caller's line.
Returning to decision block 1101, if the caller is not a recipient of the event notification, then the call manager determines if the caller is a CC recipient, at decision block 1117. If so, processing continues at decision block 1103. If not, the call manager determines, at decision block 1119 if the caller is associated with a company identifier. It if so, processing continues at decision block 1103. If not, the call manager determines, at decision block 1121, if the caller is associated with a keyword. If so, processing continues at decision block 1103. If not, the call manager ignores the call, as indicated at decision block 1115.
FIG. 12 is a flow chart of instant message status processing according to an embodiment of the present invention. The call manager checks instant message status, as indicated at block 1201. The call manager determines, at decision block 1203, if a special status is set. If not, the call manager completes the call, as indicated at block 1205. If, as determined at decision block 1203, a special status is set, then the call manager determines, at decision block 1207 if the caller is associated with a special status. If so, the call manager completes the call, as indicated at block 1205. If not, the call manager sends the call to voice mail, as indicated at block 1209. It should be recognized that IM status processing may be performed before calendar filter. Additionally, additional filtering may be performed by a smart wireless phone after the call as been completed by the call manager.
Referring now to FIG. 13, there is illustrated a block diagram of a generic information handling system 1300 capable of performing the server and client operations described herein.
