An improved handheld electronic device and an associated method also provide a call history for any phone call from the improved call log that is selected by the user. The call history includes a listing of all of the calls stored by the device that are associated with the selected call log call.

## Background
BACKGROUND
The invention relates generally to handheld electronic devices and, more particularly, to a handheld electronic device having an improved phone call log. The invention also relates to a method of logging and displaying information relating to phone calls placed with and received or missed by a handheld electronic device.
Numerous types of handheld electronic devices are known. Examples of such handheld electronic devices include, for instance, personal data assistants (PDAs), handheld computers, two-way pagers, cellular telephones, and the like. Such handheld electronic devices are generally intended to be portable and thus are relatively small. Many handheld electronic devices also feature wireless communication capability, although many such handheld electronic devices are stand-alone devices that are functional without communication with other devices.
Many handheld electronic devices include cellular telephone functionality. Such devices often store a log of phone calls placed, received and/or missed by the device in what is commonly referred to as a call log. Information contained in the call log may be selectively accessed by and displayed to the user of the handheld electronic device. Such information is useful to the user to, among other things, help to recall if and when a particular phone call was placed, received, or missed, and to access information about the call such as, for example, the associated telephone number or the name, address or email address of the person associated with the call.
Prior art call logs typically display the phone call information to the user chronologically based on the time and date associated with each call, usually beginning with the most recent call first. Some prior art call logs group and display the logged calls based on the category in which the call falls, i.e., a missed call, a received called, or a placed call. In this case, the calls are still typically displayed chronologically. No effort has been made, however, in the known prior art to group or link together all logged calls that are associated with the same originating or dialed phone number or contact person so that the user of the handheld electronic device can have a contact based view of phone call history. Thus, with known prior art call logs, if a user is interested in knowing the history of calls associated with a particular originating or dialed phone number or contact person, the user must manually search through the chronologically organized call log for all entries for that phone number or contact person.
SUMMARY
An improved handheld electronic device and an associated method provide an improved call log that presents information relating to logged phone calls in a collapsed manner, meaning that for each phone number having a call stored in the memory of the device, only the most recent in time call is listed on the call log. Another aspect of the invention is to provide a call history for any phone call from the improved call log that is selected by the user. The call history includes a listing of all of the calls stored by the device that are associated with the selected call log call.
These and other aspects of the invention are provided by a method of providing a call log on a handheld electronic device including storing call related information for a plurality of outgoing and incoming phone calls, wherein each of the phone calls is associated with a phone number, compiling a list of call log phone calls, with the call log phone calls being the most recent stored phone call for each of the phone numbers, and displaying the list to a user of the handheld electronic device. The list may include call log information for each of the call log phone calls that may include one or more of the date and time of the call, the phone number associated with the call, and a contact name associated with the call. The call log may display the calls in chronological order, beginning with the most recent call first. The method may further include displaying portions of the call related information for a selected call log call, such as the date, time and duration of and the phone number associated with the selected call.
According to a further aspect of the invention, the method may further include displaying a call history for one of the call log calls selected by the user. The call history preferably includes a listing of all of the stored phone calls associated with the phone number of the selected call log call.
According to still a further aspect of the invention, the method may include providing a menu of user options to the user for either a selected call log call or a selected call history call. The method may further include performing a function associated with the user option that is selected by the user.
According to another aspect of the invention, an improved handheld electronic device having an improved call log capability is provided that includes a display, a processor and a memory storing one or more applications executable by the processor. The one or more applications include instructions for performing the various embodiments of the improved method of proving a call log described above.

Phone application 48 of handheld electronic device 4 includes routines for providing an improved call log for providing information to the user of handheld electronic device 4 relating to outgoing phone calls placed using handheld electronic device 4 and incoming phone calls received and/or missed by handled electronic device 4.
FIG. 3 is an exemplary depiction of display 12 showing call log 56 including a plurality of calls 58 according to the invention. Call log 56 displays logged calls in a collapsed manner, meaning that for each phone number having information relating to a call or calls stored in memory 44 by phone application 48, only the most recent in time call 58 is listed on call log 56. Thus, each individual phone number having information relating to a call or calls stored in memory 44 will have a single entry in call log 56. Preferably, each of the call log calls 58 listed on call log 56 will include the date and time of the call, an icon indicating the nature of the call (i.e., placed, received or missed), and either the name of the caller or person called if that person and the phone number in question are stored as a contact by address book application 50, or the phone number associated with the call if the caller or called person is not stored as a contact. Also, call log 56 preferably lists the call log calls 58 in chronological order, beginning with the most recent call first. As will be described in greater detail below, a user of handheld electronic device 4 may select a particular call 58 from call log 56 and cause a call history associated with the selected call 58 to be displayed on display 12. In particular, the displayed call history will list all calls, incoming and outgoing, stored in memory 44 that are associated with the phone number associated with the selected call 58. The calls in the call history are preferably listed in chronological order beginning with the most recent call (which, as will be appreciated, will be the selected call 58 from call log 56).
A flowchart depicting a routine performed by processor 20 for creating and implementing call log 56 of the invention is shown in FIG. 4. In one embodiment, the routine of FIG. 4 is initiated and call log 56 is created any time phone application 48 is activated by the user of handheld electronic device 4, such that call log 56 will be the default initial view provided on display 12 for phone application 48. Alternatively, the routine shown in FIG. 4 may be initiated and call log 56 may be created and displayed upon request by the user from some other portion of phone application 48.
As shown in FIG. 4, the method begins at 100, where processor 20 obtains from memory 44 information relating to the most recent call, incoming or outgoing, for each phone number that has one or more associated calls stored in memory 44. Next, at 102, a list that includes the most recent in time call for each phone number having one or more associated calls stored in memory 44 is compiled and displayed on display 12 as call log 56. As described above, an example call log 56 is shown in FIG. 3. As used herein, the term “list” shall refer to a compilation of a series of items of information one after another that may or may not be in a predetermined order.
Next, at 104, a determination is made as to whether one of the calls 58 included as an entry on call log 56 is selected by the user, such as by highlighting the call 58 using input apparatus 16. If the answer at 104 is no, then at 106, a determination is made as to whether the user has provided a request using input apparatus 16, to exit either phone application 48 in the embodiment where call log 56 is displayed as the default view for phone application 48 or the call log view (and return to the default phone application view) in the embodiment where call log 56 is not displayed as the default view for phone application 48 but rather must be selected by user. If the answer at step 106 is yes, then the appropriate exit steps are taken at 108. If the answer is no, then the method returns to 102 to continue displaying call log 56.
If, however, the answer at 104 is yes, meaning a call 58 has been chosen by the user, then at 110 a menu 60 of user options 65 is displayed on display 12 as shown in FIG. 5. User options 65 include a number of different functions of handheld electronic device 4 that may be implemented by selecting one of the user options 65. As shown in FIG. 5, such functions may include, without limitation, initiating an application for handheld electronic device 4 for closing menu 60, for calling a selected contact stored by address book application 50, for calling the user's voicemail, for calling the contact listed in call 58, for creating and sending a short message service (SMS) message to the contact listed in call 58, for opening the call 58 to display detailed call information relating to call 58 that is stored in memory 44, for creating and displaying on display 12 a call history for call 58 as described in more detail below, for adding the phone number associated with call 58 to the speed dial list maintained by phone application 48, for deleting call 58 from call log 56, for viewing the speed dial list maintained by phone application 48, for viewing and changing operating options for phone application 48, for viewing status information relating to, for example, the duration of the last call, the total number of minutes for all calls, and the phone number of handheld electronic device 4, for providing help to the user, and for closing phone application 48. Next, at 112 of FIG. 4, handheld electronic device 4 performs the function associated with the selected user option 65, whatever it may be.
Referring to FIG. 6, a flowchart depicting a routine performed by processor 20 for displaying a call history according to the invention is shown. This routine will be initiated if the “view history” user option 65 of menu 60 (FIG. 5) is selected by the user after a particular call 58 has been selected. At 114, processor 20 obtains from memory 44 the call information for all calls associated with the phone number of selected call 58. As an alternative, if the phone number of chosen call 58 matches the phone number of a contact stored by address book application 50, call information for all calls associated with that contact may be obtained at step 114. At 116, a listing of the calls obtained at 114 is created and displayed, along with other information, on display 12 as shown in FIG. 7. As seen on FIG. 7, in addition to the listing of calls, the call history may include, without limitation, the name and phone number associated with the chosen call 58, the nature (i.e., place, received or missed) and duration of the last call, and the number of calls included in the history. Next, at 118 of FIG. 6, a determination is made as to whether a particular call from the displayed list is selected. If no call is selected, then at 120, it is determined whether the user has provided a request to exit the call history functionality. If the answer is yes, then at 122, the method returns to 102 of FIG. 4 wherein call log 56 is displayed. If, however, a call from the displayed list is selected as determined at 118, then, at 124, a menu of user options is displayed similar to menu 60 of user option 65 shown in FIG. 5. Next, at 126, handheld electronic device 4 performs the selected user option, whatever it may be.
Thus, the invention provides a handheld electronic device having functionality for providing a collapsed call log that gives a user a contact and/or phone number based view of the logged calls. In this manner, the user may readily access, view and request functions for all logged calls associated with a particular contact and/or originating or dialed phone number.
While specific embodiments of the invention have been described in detail, it will be appreciated by those skilled in the art that various modifications and alternatives to those details could be developed in light of the overall teachings of the disclosure. Accordingly, the particular arrangements disclosed are meant to be illustrative only and not limiting as to the scope of the invention which is to be given the full breadth of the claims appended and any and all equivalents thereof.
