     DESCRIPTION OF EXAMPLE EMBODIMENTS 
     Overview 
       [0017]    A method for creating a communication context includes receiving an identification (ID) of a person involved in a current communication. The ID is utilized to access a communication log to determine an active time interval between the start and finish times of a previous communication and a usage log is accessed to identify context material utilized during the active time interval. Access to context material is provided while the current communication is active. 
       DESCRIPTION 
       [0018]    Reference will now be made in detail to various embodiments of the invention. Examples of these embodiments are illustrated in the accompanying drawings. While the invention will be described in conjunction with these embodiments, it will be understood that it is not intended to limit the invention to any embodiment. On the contrary, it is intended to cover alternatives, modifications, and equivalents as may be included within the spirit and scope of the invention as defined by the appended claims. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the various embodiments. However, the present invention may be practiced without some or all of these specific details. In other instances, well known process operations have not been described in detail in order not to unnecessarily obscure the present invention. 
         [0019]    A first example embodiment will now be described that utilizes locally maintained call logs and usage logs. An example of a call log is depicted in  FIG. 1 . At a minimum the call log includes the date of the call, start time of the call, length of the call (or alternatively finish time of the call), and an identifier of the other person participating in the call.  FIG. 1  is only an example, and many other formats and types of information may be utilized without affecting the operation of this embodiment. 
         [0020]      FIG. 2  depicts an example of a usage log utilized by a Web browser. At a minimum this usage log includes a URL (Uniform Resource Locator) of a Web page accessed and the date and time of the access. 
         [0021]      FIG. 3  is an illustration of basic subsystems in a computer system workstation. In  FIG. 3 , subsystems are represented by blocks such as central processor  180 , system memory  181  including random access memory (RAM) and/or read-only memory (ROM), display adapter  182 , monitor  183 , etc. The subsystems are interconnected via a system bus  184 . Additional subsystems such as a printer, keyboard, fixed disk and others are shown. Peripherals and input/output (I/O) devices can be connected to the computer system by, for example, serial port  185 . For example, serial port  185  can be used to connect the computer system to a modem for connection to a network, or serial port  185  can be used to interface with a mouse input device. The interconnection via system bus  184  allows central processor  180  to communicate with each subsystem and to control the execution of instructions from system memory  181  or fixed disk  186 , and allows the exchange of information between subsystems. Other arrangements of subsystems and interconnections are possible. 
         [0022]      FIG. 4  is an architectural framework diagram of an example embodiment. In this example embodiment, the user utilizes a soft-phone  200  implemented by software operating on the workstation, and the call log  110  and usage log  120  are stored on the system memory  181  of the workstation. The context creation software  210  is coupled to receive a caller ID of a called or calling person. The context creation software  210  is also configured to have access to the memory  181  holding the call log  110  and usage log  120  and to the monitor  183 . 
         [0023]    The operation of the example architectural framework will now be described with reference to the flow chart of  FIG. 5 . When a call occurs  220  the ID of the other person is provided to the context creation software  222 . The ID is used to access the call log to determine the start and finish times of the most recent previous call between the parties  224 . These times are then utilized to search the usage log, in this example the usage log created by the user&#39;s Web browser, to identify URLs accessed between the start and finish time of the previous call  226 . These URLs are then displayed as the context of the present call  228 . 
         [0024]    An example of a user interface for the currently described example embodiment is depicted in  FIG. 6 . In this example, when a call occurs, a pop-up window  310  appears that includes the identity of the other person in the call and the context of the previous call. In this example, links to context documents are displayed. The user can then select any item in the context that is relevant to the present call. Alternatively, the context creation software could launch all the web pages in the context. 
         [0025]    In this example, if the user called Joe on the softphone the context creation software would receive the ID of Joe and utilize the ID to access the call log. In the example call log of  FIG. 1  the previous call to Joe was made on Aug. 22, 2007 with a start time of 11:39 AM and finish time of 11:44:37 AM. The example Web browser usage log of  FIG. 2  would be accessed to retrieve URLs of Web pages accessed between the start and finish times. The called person&#39;s name and context URLs are displayed in the user interface, in this example the pop-up window  310 . 
         [0026]    The present example embodiment utilizes the usage log of the Web browser by way of example not limitation. Other types of application software generate usage logs that may be utilized in this embodiment. For example, word processor programs keep track of time of creation, access and modification of a document. Accordingly, file pointers other than links can be displayed by the context creation software. 
         [0027]    Another example embodiment will now be described where the context is dynamic and where the context creation software uses heuristics to determine what information is important to the communicating parties. Through the use of tagging and social networking other potentially useful documents could be added to the context as well. 
         [0028]      FIG. 7  depicts an example architectural framework for this embodiment. A context database  300  is included that is utilized by the context creation software  210  to store all information in the usage log relevant to a particular ID of another person. As depicted in the flow chart of  FIG. 8 , when a call occurs involving the other person a heuristic is utilized  316  to select the context displayed in the user interface. 
         [0029]    Examples of heuristic algorithms include selecting most recently used items or the most frequently used items in the context database. Other heuristics could include forming associations with certain items so that when the item is selected associated items are also included in the heuristic. 
         [0030]    In another embodiment, depicted in  FIG. 9 , the call log and/or usage log is stored centrally on a network server  400  remote from the user&#39;s workstation. 
         [0031]    In this embodiment, as depicted in the flow chart of  FIG. 10 , after receiving the other party&#39;s ID the context creation software must access the server  414  to obtain information from the call log and usage log. The usage database can be created in the server or locally on the user&#39;s workstation. 
         [0032]    In the above described example embodiments a softphone has been utilized. However, the embodiments described can be implemented utilizing external internet phones, cell phones, or phones connected to the standard switched telephone system. Call logs can be created for any type of phone and these call logs can be utilized by the example embodiments as described above. 
         [0033]    Additionally, other types of logs may be utilized to determine search criteria to create a communication context. For example, instant messaging logs and email logs can be accessed to determine start and finish times of previous communications with another person. 
         [0034]    Another example embodiment will now be described with reference to  FIGS. 11 and 12  that considers all communications with another person and is not limited to the media used in a current communication with that person. In  FIG. 11  multiple communication logs  310  and usage logs  320  are stored on a network server  400 . Additionally a policy and preference server  500  operates on the network server  400 . 
         [0035]    In  FIG. 12 , the context creation software receives the ID of the other party of a current communication  424 . Selected communication logs, for example call logs, email logs, and instant messaging logs, are searched at the network server  428 . The search is not limited to the media used for the current communication. For example, if the current communication were by telephone all other communication logs would be searched using the ID of the other party to the current communication. 
         [0036]    The context creation software searches selected communication logs for the start and finish times of previous communications with the other party  430 . These start and finish times are used to search selected usage logs for usages occurring between accessed start and finish times. 
         [0037]    A user interface is then displayed that provides access to the communication context relevant to the current communication  432 . As described above, the context information retrieved can be stored in a database and a heuristic performed to decide which items of context are made available for the present communication. 
         [0038]    When a current communication is initiated the context creation software may access the policy and preference server to determine which modes of communication are available to the other party of the communication. This information is then used to structure the search for previous communications. Also, preferences related to the parties of the communication may be utilized by the context creation software to create a heuristic tailored to the preferences of the parties to the communication. 
         [0039]    For example, the preferences may indicate that usage log data be searched for usages by the other party only after a certain date. This information would then be used by context creation software to tailor a heuristic for creating the context. 
         [0040]    Example embodiments have been described above. Alternatives and substitutions will now be apparent to persons of skill in the art. For example, as understood by persons of ordinary skill, the actual locations of the various logs and databases in a network are not critical to practicing the invention. Accordingly, it is not intended to limit the invention except as provided by the appended claims.
