PRIORITY REFERENCE TO RELATED APPLICATIONS 
     This application claims benefit of U.S. Provisional Application No. 60/964,233, entitled CALL SHUFFLING, filed on Aug. 9, 2007 by inventors Itay Sherman, Eyal Bychkov, Hagit Perry and Uri Ron. 
    
    
     FIELD OF THE INVENTION 
     The present invention relates to automated scheduling of phone calls. 
     BACKGROUND OF THE INVENTION 
     People often find themselves in situations where they have a large number of phone calls to make. A salesperson, for example, may have a large number of contacts to follow up on with phone calls. Or a professional returning to his office from vacation may find a large number of phone messages on his answering machine which require return phone calls. Or a person may want to stay in touch with a large number of friends and family on a regular basis, and call them from time to time. 
     When such people have free time, and would like to use the time to make some of their phone calls, it is cumbersome to sort out who to call. Free time may arise sporadically when people are waiting for a service or for an appointment. Free time may also arise in predictable ways when people are exercising or traveling on a train or taxi. Even when people write themselves notes of phone calls to make, using computerized calendars or slips of paper, the notes are not always available with them during their free time. Or the notes may be extensive and difficult to sort through and prioritize. 
     Thus it would be of advantage to have an automated way of making phone calls during free time. 
     SUMMARY OF THE DESCRIPTION 
     The present invention provides a simple and efficient way for a person to automatically schedule phone calls to make, whenever he has free time to make some of his calls. The present invention provides a call shuffler that arranges the person&#39;s calls that have to be made in order of priority, and places the calls. The person does not have to sort through and review his notes to determine what calls to make. 
     The present invention organizes a person&#39;s contacts into groups, one group being contacts that a person wants to call. The contacts are assigned priorities based on factors including inter alia importance, deadlines and special dates such as birthdays and anniversaries, and length of time since the person last spoke with a contact. Whenever the person has free time, the contacts are sorted in terms of priority, contacts with the same priority are randomly sorted, and phone calls are placed accordingly. 
     Priorities are updated dynamically, when factors influencing priorities change, and after phone calls are made. 
     There is thus provided in accordance with an embodiment of the present invention a method for automatically scheduling phone calls, including dynamically assigning priorities to each of a plurality of a user&#39;s contacts, selecting one of the plurality of the user&#39;s contacts based on highest priority, wherein random selection is used in case more than one contact has the highest priority, placing a phone call to the selected contact, and updating the priority of the selected contact, if the placing a phone call successfully reaches the selected contact. 
     There is additionally provided in accordance with an embodiment of the present invention a telephone with an automatic call scheduler, including a memory for storing a plurality of a user&#39;s contacts and priorities assigned thereto, a prioritizer coupled with the memory for dynamically assigning the priorities to the plurality of the user&#39;s contacts, and for updating the priority of a contact when a phone call is successfully made to the contact, a scheduler coupled with the prioritizer and with the memory for selecting one of the plurality of the user&#39;s contacts based on highest priority, wherein the scheduler uses random selection in case more than one contact has the highest priority, and a dialer coupled with said scheduler for automatically placing a phone call to the selected contact. 
     There is moreover provided in accordance with an embodiment of the present invention a computer readable storage medium storing program code for causing a telephone to dynamically assign priorities to each of a plurality of a user&#39;s contacts, to select one of the plurality of the user&#39;s contacts based on highest priority, wherein random selection is used in case more than one contact has the highest priority, to place a phone call to the selected contact, and to update the priority of the selected contact, if the placed phone call successfully reaches the selected contact.

     DETAILED DESCRIPTION 
     The present invention relates to automatic phone call scheduling for some or all of a user&#39;s contacts. The user&#39;s telephone stores his list of contacts, and includes a profile for each contact. Shown in TABLE I is a sample contact profile, in accordance with the present invention. In addition to the contact&#39;s name, phone number and relation to the user, the contact profile includes fields for preferred calling dates and times, excluded calling dates and times, one or more special occasions and desired frequency of calls. 
     The contact profile also includes a free-text field for storing comments. The free-text field may include reminders as to why the user wants to speak with the contact. The contact profile also includes a schedule call flag. Setting the schedule call flag to ON indicates that the user would like to call the contact when he has the time to do so. For example, the contact may be waiting for a return phone call from the user, or the contact may be someone the user wants to stay in touch with professionally or personally.

     Reference is now made to  FIG. 1 , which is a simplified block diagram of a telephone  100  with automated call scheduling, in accordance with an embodiment of the present invention. Telephone  100  may be a land-line telephone or a cellular telephone. Telephone  100  is operated by a user, or by a number of users. 
     As shown in  FIG. 1 , telephone  100  includes a central processing unit (CPU)  110 , a power subsystem  120 , an audio subsystem  130 , a keyboard  140  for user input, a display  150  for output, a SIM card  160 , and a power amplifier  170 . Power subsystem  120  generally includes a rechargeable battery. Keyboard  140  generally includes a small keypad for dialing phone numbers and entering SMS messages. Display  150  is generally a small LCD display. Power amplifier  170  is connected to a GSM antenna. 
     Telephone  100  also includes a memory unit  180 , which stores user data such as contact information for the user&#39;s contacts, SMS messages and phone settings. In accordance with an embodiment of the present invention, user contact information is imported from external databases, such as Facebook® databases managed by Facebook, Inc. of Palo Alto, Calif, or databases from such other social or dating services. 
     Memory unit  180  also stores program code  190  that executes application programs, such as an Internet browser and a personal organizer. In accordance with the present invention, program code  190  also executes an automated call scheduler  200 , which is used to schedule and dial telephone calls. 
     Reference is now made to  FIG. 2 , which is a simplified block diagram of automated call scheduler  200  of telephone  100  of  FIG. 1 , in accordance with an embodiment of the present invention. Shown in  FIG. 2  is a data store  210 , within memory unit  180 , which stores a user&#39;s contacts and their profiles. Some or all of the contacts are designated by the user as being “shuffle-able”; i.e., contacts that the user would like to call when he has free time to do so. For example, the user may designate that contacts that are waiting for a reply phone call from him are shuffle-able. He may also designate that certain friends and family are shuffle-able, as a way of staying in touch with them. In accordance with an embodiment of the present invention, a contact is designated as shuffle-able by setting the schedule call flag in the contact&#39;s profile to ON. 
     A dynamic prioritizer  220  dynamically assigns a priority to each of the user&#39;s shuffle-able contacts, based on a variety of factors. The priorities assigned to the contacts are stored in data store  210 , together with the contacts&#39; profiles. The factors influencing the calculation of a contact&#39;s priority include inter alia:
         a special date relating to the contact, such as the contact&#39;s birth date or wedding anniversary, or Mother&#39;s Day or Father&#39;s Day;   the time remaining until a designated deadline for calling the contact;   the time elapsed since the user last spoke with the contact;   the desired frequency for which the user wishes to speak with the contact;   a metric of importance assigned to the contact;   a status of the contact, such as “busy”, “available”, “running” and “on another phone call”;   contact&#39;s preferred dates and times to call him; and   contact&#39;s excluded dates and times to call him.       

     In accordance with an embodiment of the present invention, telephone  100  includes an activation button for activating automated call scheduler  200 . Thus, when the user has free time to make some of his calls, he may activate automated call scheduler  200  by pressing on the activation button. Phone call scheduler  230  then dynamically sorts the shuffle-able contacts in terms of their priorities, and selects the highest priority contact for placing a phone call. In case multiple contacts have the highest priority, phone call scheduler  230  chooses randomly among them. As such, in a case where all priorities are the same, phone call scheduler  230  uses random selection among all the shuffle-able contacts. 
     After selecting a shuffle-able contact to be called, a user prompter  240  notifies the user of the selected contact, for his confirmation. Such notification may be visually or vocally, or both. User prompter  240  is configured to present information from the selected contact&#39;s profile to the user, to remind the user why he wanted to call the selected contact, and to assist the user in deciding whether to confirm or decline making the call. Information presented to the user by prompter  240  may include inter alia the free-form text from the selected contact&#39;s profile, the last date and time that the user made a phone call to the selected contact, and any special occasion related to the selected contact. 
     If the user confirms the call, then an automated dialer  250  places the call. If the phone call to the selected candidate is successful, then phone call scheduler updates the contact&#39;s priority appropriately. An unsuccessful phone call to a contact is a call for which a busy signal is reached, or for which the contact is not available. In accordance with an embodiment of the present invention, success or non-success of a call is measured by the duration of the call. Calls with duration over 15 seconds, for example, may be deemed successful. 
     Generally a contact&#39;s priority is reset to a low value after a successful call to the contact is made. However, in certain cases the contact&#39;s priority may remain high, such as when the user needs to call the contact back again in order to finish the discussion. The call may have been cut off, or the user or the contact may have run out of time, or the user may need to get more information from the contact. 
     It will thus be appreciated by those skilled in the art that the telephone of  FIG. 2  enables the user to manage a large number of phone calls that he would like to make, and automatically select one or more phone calls whenever the user has free time to speak with his contacts. 
     In an embodiment of the present invention, the user&#39;s shuffle-able contacts may be grouped in categories, such as “sports contacts”, “family contacts” and “dating contacts”. When activating automated call-scheduler  200 , the user may designate a specific group of contacts, in which case phone call scheduler  230  selects from among the designated group of shuffle-able contacts. 
     In some embodiments of the present invention, telephone  100  is implemented as a modular cell phone that attaches to other electronic devices. There are two general types of devices to which the modular cell phone may be attached; namely, jackets and hosts. A jacket is a device that provides a user interface for the modular cell phone, enriches the capabilities of the modular cell phone, and is not able to operate independently when the modular cell phone is not pouched therewith. Conversely, a host is a device that is able to operate independently when the modular cell phone is not pouched therewith, and whose capabilities are enriched by the modular cell phone when the modular cell phone is attached thereto. Generally a host does not have communication functionality independent of the modular cell phone. 
     In this regard, reference is now made to  FIG. 3 , which is an illustration of a modular cell phone  300  being inserted into a jacket/host  400 , in accordance with an embodiment of the present invention. Jacket/host  400  as shown in  FIG. 3  includes a hollow cavity at the top for insertion of modular cell phone  300  therein. 
     Reference is now made to  FIG. 4 , which is a simplified illustration of a communication system constructed and operative in accordance with an embodiment of the present invention. Shown in  FIG. 4  are a variety of modular cell phones  300   a - 300   c , including 2.5G communicators for a GSM network, 3G communicators for GSM network, and CDMA communicators for a CDMA network. It will be appreciated by those skilled in the art that the networks in  FIG. 4  are exemplary of a wide variety of networks and communication protocols that are supported by the wireless communicators of the present invention, such networks and communication protocols including inter alia WiFi, Bluetooth and WiMax. 
     Also shown in  FIG. 4  are a variety of jackets/hosts  400   a - 400   h , including car jackets/hosts, sports jackets/hosts, camera jackets/hosts, gaming jackets/hosts, etc. In accordance with an embodiment of the present invention, each modular cell phone  300   a - 300   c  may be attached to any of the jackets/hosts  400   a - 400   h , so as to operate in combination therewith. The modular cell phones  300   a - 300   c  are substantially of the same form factor and, as such, are able to be attached to each of the various jackets/hosts  400   a - 400   h.    
     Reference is now made to  FIG. 5 , which is a simplified flowchart of a method for automatically scheduling phone calls, in accordance with an embodiment of the present invention. At step  510  a user has time to speak with his contacts, and selects a “shuffle-call” function on his telephone. Some or all of the user&#39;s contacts are designated as being “shuffle-able”; i.e., contacts that the user would like to call when he has the time to speak with them. 
     In an alternative embodiment of the present invention, the shuffle-call is pre-scheduled by the user. For example, the user may insert a shuffle-call event into his calendar. 
     In yet another embodiment of the present invention, the shuffle-call is automatically suggested to the user when specific conditions prevail. The shuffle-call may be automatically suggested to the user inter alia:
         when his calendar is empty, but is generally not empty most of the time;   when the user changes his status on Facebook®, or on an instant messaging service, to “available”;   when a user&#39;s contact changes his status to “available” on Facebook®, or on an instant messaging service; and   when telephone  100  is a modular cell phone  300 , and the user inserts the communicator into a car jacket/host  400 .       

     At step  520  priorities are assigned to the user&#39;s shuffle-able contacts, based on various factors as described hereinabove with reference to prioritizer  220 . It will be appreciated by those skilled in the art that step  520  may be performed after step  510 , as shown in  FIG. 5 , or, alternatively, step  520  may be performed at regular time intervals, such as every 30 seconds, in order that a current prioritization always be readily available. In this alternative embodiment, processing moves from step  510  directly to step  530 . 
     At step  530  the contact with the highest priority is selected. In case more than one contact has the highest priority, then one of them is chosen by random selection. 
     At step  540  the user is informed of the selected candidate contact, and given the opportunity at step  550  to confirm whether or not he wishes to call the contact now. In accordance with an embodiment of the present invention, at step  540  any free-text comments in the contact&#39;s profile are presented to the user, so that the user can be reminded why he wanted to call the contact. Other information from the contact&#39;s profile may be presented to the user instead of or in addition to the free-text comments, such as the last date and time the user spoke with the contact, or today being a special occasion related to the contact. The choice of which information from the contact&#39;s profile to present to the user at step  540  is preferably configured by the user. 
     If the user declines at step  550 , then processing returns to step  530  where the next contact in line is chosen. If the user confirms, then at step  560  a phone call to the selected contact is automatically placed. The user may configure his telephone to skip step  550 , in which case phone calls to selected contacts are always placed. 
     The phone call placed at step  560  may or may not be successful, as determined at step  570 . An unsuccessful call to a contact is one where the contact is not available, or where the call reaches a busy signal. In accordance with an embodiment of the present invention, success or non-success of a call may be determined from the duration of the call. For example, calls with duration over 15 seconds may be deemed successful. 
     If the call was unsuccessful, processing returns to step  530 . If the call was successful, then the contact&#39;s profile is updated appropriately at step  580 . Processing then returns to step  520 , as long as the user continues to make phone calls. 
     It will be appreciated by those skilled in the art that the method of  FIG. 5  enables a user to place phone calls without having to decide a-priori which contacts to call. As such, the user saves time by not having to decide who to call, and the user automatically stays in touch with friends and family. 
     Assignment of Priorities 
     Step  520  of  FIG. 5  involves assigning priorities to user contacts, based on their profiles. In accordance with an embodiment of the present invention, a scoring function is used to accumulate various factors that impact the priority of a user contact. TABLE II below indicates some sample score factors, which cumulatively determine the priority.

     The “closeness of relationship” factor in TABLE II may be input by the user, or may be automatically derived from external databases. For example, certain contacts may have been designated by the user as “best friends” on one or more social databases. 
     It will be appreciated by those skilled in the art that the factors shown in TABLE II are representative of a wide variety of factors. The theme of jacket/host  400  used with modular cell phone  300  may be used in calculating priorities; i.e., contacts related to the theme of jacket/host  400  are assigned higher priorities. E.g., if modular cell phone  300  is housed in a sports jacket  400 , then sports contacts are assigned higher priorities; and if modular cell phone  300  is housed in a gaming host, then gaming contacts are assigned higher priorities. Even astrological factors may be used in calculating priorities; e.g., this is a good day to call contact X, since he is an Aries. 
     In addition to the factors shown in TABLE II, a user&#39;s contact&#39;s priority may be changed when the contact sends to the user an SMS message requesting a phone call, or when the contact&#39;s status changes from “busy” to “available” on an Internet communication service. 
     Reference is now made to  FIG. 6 , which is a simplified block diagram of a communication system with functionality for notifying a user when a contact&#39;s status becomes “available” on an Internet communication service, in accordance with an embodiment of the present invention. Shown in  FIG. 6  are telephones  100  belonging to a user and to two of the user&#39;s contacts, contact # 1  and contact # 2 . Also shown in  FIG. 6  are computers  600  belonging to two others of the user&#39;s contacts, contact # 3  and contact # 4 . Computers  600  are connected to various web sites  610 , which provide communication services, such as Facebook® or an instant messaging service. The communication services enable contact # 3  and contact # 4  to set an availability status, with settings such as “busy”, “available”, “running” and “on another phone call”. The availability statuses are transmitted to a status server  620 , which communicates with web sites  610  using an API, such as an API for XML exchange, and notifies telephones  100  when contact  3  or contact  4  becomes available. 
     In accordance with a first embodiment of the present invention, the user&#39;s contacts (contact # 3  and contact # 4 ) need not have telephones  100 , and notification of contact availability is performed through a social network. The user&#39;s telephone  100  has a Facebook® or instant messaging application installed therein. Web sites  610  report availability of contact # 3  and contact # 4  to status server  620 , using the API. In turn, status server  620  notifies the application in telephone  100  accordingly. 
     In accordance with a second embodiment of the present invention, the user&#39;s contacts (contact # 1  and contact # 2 ) each have a telephone  100 , and notification of contact availability is performed directly through status server  620 . Telephones  100  broadcast availability statuses to status server  620 . Telephone  100  may, for example, send an HTTP request to status server  620 , the request including status information of contact # 1  or contact # 2 , and device information for the contact&#39;s telephone  100 . Status server  620  maintains the status/telephone data, and reports back the status of contact # 1  and contact # 2  to the user&#39;s telephone  100 . Status server  620  may, for example, send an HTTP response to telephone  100 , or alternatively telephone  100  may download the status information from status server  620 . 
     In the foregoing specification, the invention has been described with reference to specific exemplary embodiments thereof. It will, however, be evident that various modifications and changes may be made to the specific exemplary embodiments without departing from the broader spirit and scope of the invention as set forth in the appended claims. Accordingly, the specification and drawings are to be regarded in an illustrative rather than a restrictive sense.
