BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The present invention relates to a method and apparatus for providing presence management. In particular, the present invention relates to a method and apparatus for integrating a presence management system with a universal messaging platform to enable tracking and establish communication links across multiple modes of communication.  
         [0003]     2. Description of the Related Art  
         [0004]     Presence Management provides a method for delivering a message to an intended recipient when the recipient has moved from one contact point, such as a telephone, to another. Call forwarding is an example of a Presence Management system in which a call originally placed to one phone number is transferred to another phone number. If a recipient does not pick up, a voicemail option is often available as well. In some presence management systems, a phone system can ring phones in parallel or serial (in an assigned order). In other words, when a call is made, all phone numbers stored in a database are rung at once. Alternatively, the phone stored phone numbers can be rung in a sequential order.  
         [0005]     With the proliferation of newer technologies, there are more modes of communication available, such as phone, text messaging, email, pager, etc. For example, some people have several phone numbers and email addresses at which they can be reached. Current technologies are able to integrate various aspects of presence management. Voicemail can be integrated into Microsoft Exchange or Lotus Notes environment, for example. Also, Microsoft Live Communication Server (LCS) offers Presence Management integration for Microsoft Applications. In general, a user can keep their Microsoft Exchange Server on customer premises and integrate messaging between the Exchange and a network-based messaging platform. Another option is for customers to leverage a Unified Messaging Platform residing on a processor with memory to store email. A more sophisticated Presence Management System is generally needed that can be used to deliver messages across these multiple modes of communication.  
       SUMMARY OF THE INVENTION  
       [0006]     The present invention provides presence management to a multimodal communication network. A unified messaging platform is integrated with a presence managing system. The unified messaging platform provides the ability to deliver messages across multiple modes of communication. In other words, a message that is sent in one mode of communication can be delivered in another mode of communication. For example, a textual message originating as an email can be converted into a voice message to be delivered by telephone. Conversely, a voice message originally spoken into a telephone receiver can be converted to text and delivered as an email. The presence management system stores contact information in a time-related fashion to indicate where a recipient may be at a given time. A unified messaging system receives a message for a recipient from a sender. The unified messaging system retrieves contact information related to the recipient from a presence management system. The recipient is then contacted at a communication device indicated in the retrieved contact information. Once the recipient receives the message, a response can be sent to the sender along the established line of communication. The multimodal communication network can comprise, for instance, wireline telephone communication, wireless telephone, electronic mail, pager, Voice over Internet Protocol (VoIP), Personal Digital Assistant (PDA), video, picture, etc.  
         [0007]     In one aspect of the invention a method and apparatus are provided for providing presence management in a communication network. The method and apparatus receive a message for a recipient from a sender at a unified messaging system (UMS). A function on the UMS retrieves contact information from a presence management system for the recipient and the function contacts the recipient in accordance with the contact information. The method and apparatus further receive a response from the recipient to the message at the unified messaging system and send the response to the sender. The message is sent and received in one communication mode of the unified messaging system comprising at least one email, cell phone; and text display. A message response is sent to the sender. The message and response may be sent and received in different communication modes. A presence management system provides a database for storing contact information. The contact information further may comprise alternate telephone numbers; email addresses; pager numbers; and personal addresses.  
         [0008]     In another aspect of the invention a set of application program interfaces are embodied on a computer readable medium for execution on a computer in conjunction with an application program that provides presence management in a communication network. A first interface is provided that receives a message for a recipient from a sender at a unified messaging system. A second application program interface is provided that receives contact information from a presence management system for the recipient. A third application program interface is provided that receives contact information for contacting the recipient in accordance with the contact information. A fourth application program interface is provided for receiving a response from the recipient to the message at the universal messaging system and sending the response to the sender. The message is received in one mode of the unified messaging system.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0015]     In view of the above, the present invention through one or more of its various aspects and/or embodiments is presented to provide one or more advantages, such as those noted below.  
         [0016]     The present invention provides presence management over multiple modes of communication, including, among others, Voice over Internet Protocol (VoIP) telephony, email, cellular phones, and chat messages. One embodiment of the present invention uses an E-mail/Calendar application, such as Microsoft Outlook, for example, as a central presence management system.  
         [0017]      FIG. 1  illustrates a connection diagram  100  in one aspect of the present invention integrating a messaging platform with a presence management system. A Network-based Unified Messaging Platform  102  comprising a programmed computer with memory is coupled to a Desktop Calendar Schedule located at a web access point  101 , such as a desktop computer, and to a Presence Management System  103  residing on a computer with memory. The Unified Messaging Platform provides conversion capabilities between modes of communication, such as a Speech-to-Text and Text-to-Speech conversion application for forwarding voice messages to a users text device or text email to a phone. The Presence Management System provides a central storage location for contact information, such as telephone numbers and email addresses. The Unified Messaging Platform can communicate with the Presence Management System and the Desktop Calendar Schedule using a suitable protocol, such as Internet Protocol. A signaling protocol, such as Session Initiation Protocol (SIP) can also be used to transfer information from the Presence Management System. The Desktop Calendar Schedule and the Presence Management System provide contact information to the Unified Messaging Platform can access. A client typically enters contact information at a web access point  101  using services such as an Email or Calendar application. Calendar and email information can be stored either directly at the web access point  101  or on the centrally located presence management system  103 .  
         [0018]     A suitable calendar application, such as Microsoft Outlook, can be used to store contact information in a schedule. In an exemplary embodiment, Microsoft Outlook enables a user to store presence information in a file on the desktop computer, such as using a .pst file. If the user stores all contact information in .pst file on their computer, then the Unified Messaging Platform accesses the information from the web access point  101 . If data is stored centrally, communication can be held with the central storage unit (i.e., Presence Management System) instead.  
         [0019]      FIG. 2  illustrates an exemplary implementation  200  of the present invention in which a Unified Messaging Platform  202  routes a message according to contact information stored in a Presence Management System  220 . A sender sends an message  201  (in this illustration, an email) to the Unified Messaging Platform  202 , on which the intended recipient has an account. The Unified Messaging Platform receives the email and checks the Presence Management System for user availability and contact information to enable delivery of the message. Additionally, the Unified Messaging Platform validates the recipient&#39;s contact information (i.e. phone number) against the information retrieved from the Presence Management System  203  to verify that the message can be delivered using an available and appropriate mode of communication. This information is relayed back to the Unified Messaging Platform  204  to convert email to a voice message.  
         [0020]     The message is converted at the Unified Messaging Platform from one mode of communication to another when desired. In  FIG. 2 , the recipient is available at cell phone  206 , which connects to the Unified Messaging Platform  202  via a Public Switched Telephone Network (PSTN)/Cellular Network  205 . While the message originates as an e-mail message, the recipient is equipped to receive a voice message. The Unified Messaging Platform converts the email to voice and then calls the recipient at the cell phone number over the cellular network  205 . If the recipient picks up the call, the Unified Messaging Platform delivers the voice message to the cell phone  206 .  
         [0021]     The present invention further provides “Session Persistence,” in which a line of communication, once established, can be sustained. In the example of  FIG. 3 , the Unified Messaging Platform maintains the line of communication established in  FIG. 2  so that the recipient can communicate a response back to the sender. In one example of response, upon receiving a voice message at a cell phone, the recipient can speak a response into the cell phone. Alternatively, the recipient may only wish to acknowledge that a message has been received rather than respond to the content of the message. In this case, the recipient might, for example, push a single button to acknowledge receipt of a message.  
         [0022]      FIG. 3  illustrates a previously established communication link  300  over which a response can be returned. A voice response at cell phone  301 , for example, can be sent via PSTN/Cellular Network  305  to the Network-Based Unified Messaging Platform  302 . It is converted at the UMS to the appropriate mode of communication for receipt by the sender (i.e. email). From the Unified Messaging Platform  302 , the converted response is delivered to the sender&#39;s email address  303  (as indicated in the original email).  
         [0023]      FIG. 4  illustrates a screenshot  400  of an exemplary scheduling application usable in association with the present invention. The Presence Management System  220  maintains a schedule of contact information stored on it. This receiver information is relayed back to the Unified Messaging Platform  204  upon request. Contact information includes, for example, mobile, phone number, SIP address (email for IP call), and email for written correspondence, among others. In another aspect of the present invention, Voice over Internet Protocol (VoIP) is integrated with the presence management system. The screenshot  400  displays a Microsoft Outlook calendar with contact information stored as entries. There are numerous email/calendar applications in addition to Microsoft Outlook which are suitable for use with the present invention. The function of presence management can be integrated into the calendar application. Once contact information has been entered into the calendar, this information is accessible by the Unified Messaging Platform. Also, the user can add fields to provide instructions for use of the contact information. For example, the user may wish to use his home phone or private contact to be reached for a specific event, but not on a regular basis. These options can be provided using an appropriate calendar application.  
         [0024]     In screenshot  400 , a phone number is provided for the time slot from 9:00 am to 9:30 am, during which an office phone  401  is provided; from 10:30 am to 12:00 pm, during which a cellular phone number  404  is provided; from 1:00 pm to 3:00 pm, at which time a home phone number  409  is provided; and finally, from 4:00 pm and 5:00 pm, during which time an email address  413  is provided while the recipient is in a conference. This information is accessed when a message is received at the messaging platform. For example, a call received at 2:00 pm is transferred to the home phone number indicated from 1:00 pm to 3:00 pm. As some further possibilities, a schedule entry can be marked as “Available for Communication” or “Offline”. An “Offline” entry might result in forwarding of voice and email to a storage destination for later pickup, such as voicemail.  
         [0025]      FIG. 5  illustrates a flowchart  500  describing establishing a connection between sender and recipient using the presence management system of the present invention. In Box  501 , the Network-Based Unified Messaging Platform receives an incoming message from a sender for an intended recipient. The message can be sent using any number of modes of communication. In Box  503 , the Network-Based Unified Messaging Platform retrieves contact information from the Presence Management System indicating a method of contact for the message. In Box  505 , the message is sent to the recipient at the contact location. If the mode of communication is different for the sender and the recipient (i.e. sender is using a telephone and recipient is using email), the message is converted from the sender&#39;s mode of communication to the recipient&#39;s mode of communication before sending the message to the recipient. The recipient&#39;s mode of communication can be derived from the retrieved contact information. In Box  507 , the recipient can send a message response to the sender over the established link. The Network-Based Unified Messaging Platform receives the message response from the recipient and sends the response to the sender. Any appropriate conversions between the modes of communication of sender and recipient are made at the Network-Based Unified Messaging Platform.
