No. 7,076,275, and assigned to the assignee of the present application. The subject matter in the above-identified and commonly owned applications is incorporated herein by reference.
- 1. Field of the Invention
- The present invention relates to the field of portable electronic devices such as personal digital assistants or palmtop computer systems. Specifically, the present invention relates to a method and system for allowing a background task to run on a portable electronic device facilitating telephony functionality on the portable electronic device.
- 2. Related Art
- As the components required to build a computer system have reduced in size, new categories of computer systems have emerged. One of the more recent categories of computer systems is the portable or “palmtop” computer system, or personal digital assistant (PDA). A palmtop computer system is a computer that is small enough to be held in the hand of a user and is thus “palm-sized.” As a result, palmtops are readily carried about in a briefcase or purse, and some palmtops are compact enough to fit into a person's pocket. By virtue of their size, palmtop computer systems are also lightweight and so are exceptionally portable and convenient.
- The emergence of the cellular phone technology in the last few years has revolutionized the telecommunications industry. Where in the past telephones were largely confined to homes, offices, and other stationary structures, cellular phone technology has made it possible for phones to be—truly portable and exist nearly anywhere there are people.
- Recently, the technology behind both palmtop computer systems and cellular phones has advanced to the point where it is proposed to integrate cellular phone capabilities into a palmtop computer system, while not increasing the size of the palmtop device. However, the operating systems that control some palmtop computer systems (for example, Palm computer systems) have not been designed especially with cellular phone technology in mind. As a result, difficulty arises for answering incoming calls when palmtop devices are in certain modes.
- Referring to
FIG. 1 , oneprior art process 100 for answering an incoming phone call on a telephony enabled palmtop computer system is shown. Instep 105, an incoming phone call is received by the operating system. The operating system then determines instep 110 whether or not the graphical user interface is busy, e.g. waiting for information from a user. In the event that the graphical user interface is not busy, the incoming phone call interrupt activates causing the device to ring (step 115) and the user may answer the phone call (step 120). However, when the graphical user interface is busy, the incoming call may become ignored thereby preventing the phone call from being answered (step 125). - The graphical user interface of a palmtop computer systems is partially controlled by the operating system. While the operating system is classified as multitasking, all user interfacing is done under one “thread.” As a result, on some occasions, an application may block the operating system from running any other applications. This occurs when the application at use requires a user input through a graphical user interface. In this case, the operating system will not run any other applications until the user has entered an input. The application at use may also block the operating system from running other applications if the application is not processing system events in a timely manner. It would be advantageous to provide an electronic device that is portable and integrates cellular phone technology with portable computer system technology and that facilitates telephony functions regardless of the software state of the portable computer system.
- Accordingly, what is needed is a method and/or system that enables the user of a device, such as a palmtop computer system or a PDA, to answer incoming phone calls using the device even when a graphical user interface of the device is awaiting a user input, and is therefore blocked. What is also needed is a method and/or system for notifying the user of an incoming call when the graphical user interface is blocked. In addition, what is needed is a method and/or system that can satisfy the above needs and that is user-friendly and convenient. The present invention provides these advantages and others not specifically mentioned above but described in the sections to follow.
- A method and system are described for automatic delivery of a phone call on a palmtop device (e.g. a palmtop computer system or a PDA) regardless of whether other tasks are running on the operating system. Embodiments include a separate background task (“thread”) interfacing directly with the telephony functionality of the palmtop device to enable telephony functionality regardless of the state of the graphical user interface. In one embodiment, the background task, which runs under the operating system, is always active and functions to monitor an interrupt line and controls the serial port connected to a phone chipset/module. The background task responds to an incoming call even if the user is in a graphical user interface window that requires some input from the user (e.g. the user interface is blocked), and the task alerts the user of the incoming phone call. Therefore, calls can be answered using the device regardless of the state of the graphical user interface. The background task also senses any of the palmtop device's telephony buttons and controls any ringer, vibrator or LEDs of the device's hardware, as well as any buttons located on a headset or earpiece connected to the device.
- One embodiment is relevant when the graphical user interface is not blocked and one or more phone related displays can automatically be displayed on the device's screen. The phone related displays are similar to those displayed on cellular phones. The background task monitors for and receives incoming phone calls, interfaces with the graphical user interface to display any call information on the device's screen, alerts the user as to the incoming call (via any ringer, vibrator and/or LEDs), and permits the user to answer the phone via a button on the palmtop device itself or a button on any earpiece or headset the user is operating.

This allows a user to be alerted to an incoming phone call (via any ringer, vibrator and/or LEDs) and to answer the phone via a button on the device itself or a button on any earpiece or headset the user is operating, without requiring the use of the device's LCD screen or the screen digitizer.
- In accordance with the present embodiment of the present invention, the telephony functionality is automatically implemented in the background transparent to the user, and thus is convenient and user-friendly. In addition, the user is notified of an incoming phone call even when the graphical user interface is blocked, therefore greatly enhancing the usefulness and commercial practicability of palmtop computer system with telephony functionality.

However, it will be recognized by one skilled in the art that the present invention may be practiced without these specific details or with equivalents thereof. In other instances, well known methods, procedures, components, and circuits have not been described in detail as not to unnecessarily obscure aspects of the present invention.
- Some portions of the detailed descriptions, which follow, are presented in terms of procedures, steps, logic blocks, processing, and other symbolic representations of operations on data bits that can be performed on computer memory. These descriptions and representations are the means used by those skilled in the data processing arts to most effectively convey the substance of their work to others skilled in the art. A procedure, computer executed step, logic block, process, etc., is here, and generally, conceived to be a self-consistent sequence of steps or instructions leading to a desired result. The steps are those requiring physical manipulations of physical quantities. Usually, though not necessarily, these quantities take the form of electrical or magnetic signals capable of being stored, transferred, combined, compared, and otherwise manipulated in a computer system. It has proven convenient at times, principally for reasons of common usage, to refer to these signals as bits, values, elements, symbols, characters, terms, numbers, or the like.
- It should be borne in mind, however, that all of these and similar terms are to be associated with the appropriate physical quantities and are merely convenient labels applied to these quantities.
