BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates generally to handheld electronic devices and, more particularly, to a handheld electronic device that utilizes phone related inputs, for example from <SEND> and <END> keys, across multiple applications executed by the device. The invention also relates to a method of utilizing phone related inputs across multiple applications executed by the device.

2. Description of the Related Art

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 and provide access to a wide range of integrated applications, including, without limitation, email, telephone, short message service (SMS), multimedia messaging service (MMS), browser, calendar and address book applications, such that a user can easily manage information and communications from a single, integrated device. These applications are typically selectively accessible and executable through a user interface that allows a user to easily navigate among these applications.

Many devices that provide telephone functionality include dedicated <SEND> and <END> keys, or the like, for enabling a user to initiate a new call, answer an incoming call, or terminate a call that is in progress. The <SEND> key, however, is typically only able to initiate a call after the user has either: (i) entered or initiated the device\'s telephone application and entered a phone number or selected a stored phone number (such as in a call log), or (ii) entered or initiated the device\'s address book application and selected a stored phone number. In such a device, the <SEND> and <END> keys are not able to be used from other active applications to initiate telephone related activity. However, with more and more handheld electronic devices including multiple applications, it would be convenient and useful for a user to be able to quickly and easily initiate telephone related activity from applications other than the telephone and address book applications, particularly those applications that may include contact related information for an individual that the user desires to call. For example, a user may receive an email, SMS message or MMS message from an individual and may, while viewing the email, SMS message or MMS message in the associated application, desire place a call to that individual. With known handheld electronic devices, the individual would need to leave the current application (e.g., email, SMS or MMS), activate the telephone application, either enter that individual\'s phone number or access that individual\'s phone number from the address book application, and activate or depress the <SEND> key. These steps, while ultimately achieving the purpose of placing the desired call, are inconvenient and time consuming. Thus, there is a need for a handheld electronic device that will enable a user to utilize phone related inputs, such as the activation (e.g., depression) of the <SEND> key, to execute phone related functions while another application is active and in use.

SUMMARY

An improved multi-application handheld electronic device and an associated method provide added convenience for the user by enabling the user to quickly and easily initiate telephone related functions, such as placing a phone call, directly from applications other than the device\'s phone and address book applications using a dedicated phone related key. A user, when using an application other than the phone or address book application, no longer needs to exit or navigate out of the current application and activate the phone or address book application to initiate telephone functionality, as was the case in the known prior art.

These and other aspects of the invention are provided by a method of using a dedicated phone related key of a handheld electronic device, such as a <SEND> or <END> key, to initiate and execute phone related functions. The handheld electronic device includes a plurality of applications including a phone application, an address book application, and one or more other applications. The device also includes a plurality of use states that are based on the application or portion thereof that is currently active and the information, if any, that is selected by the user. Each one of the plurality of use states has an associated function that is to be initiated upon depression of the phone related key.

The method of the invention includes detecting that the phone related key has been depressed by a user, and then determining the current use state of the handheld electronic device. The current use state is one of the plurality of use states that has an associated function as described above. Also, one of the other applications (other than the phone and address book applications) is the currently active application in the current use state. The method, after determining the current use state, further includes making the phone application active and initiating and executing the function that is associated with the current use state.

According to one aspect of the invention, a portion of information comprising contact related information is selected by the user in the current use state, and the associated function comprises placing a phone call based on the selected portion of information. The contact information may include a phone number, wherein the phone call will be placed to the phone number. Alternatively, the contact related information, such as a person\'s name or an email address, may be used to search the entries stored by the address book application to find an associated phone number. Once found, the phone call is placed to the phone number. The other applications of the handheld electronic device may include one or more of a messaging application, such as an email, SMS or MMS application, a browser application, a memo application, a calendar application, and a task application.

According to another aspect of the invention, in the current use state the user is connected to an active phone call. When the phone related key, such as a <SEND> key, is depressed, the handheld electronic device activates a conference call routine for conferencing another call in to the current call.

According to another aspect of the invention, an improved handheld electronic device is provided that includes an input apparatus including a dedicated phone related key such as a <SEND> or <END> key, a processor, and a memory. The memory stores a phone application, an address book application, and one or more other applications executable by the processor. The memory also stores use state information inducing a plurality of use states of the handheld electronic device and a phone related function associated with each use state that is to be initiated upon depression of the phone related key. The memory further stores one or more routines executable by the processor that include instructions for implementing the various embodiments of the method for using a dedicated phone key to initiate and execute phone related functions across applications as described above.
