ABSTRACT:
FIELD OF THE INVENTION
The present invention is related generally to a wireless communication device and, more particularly, to a system and method for parsing numbers displayed on a display to assist in operating a wireless communication device.
DESCRIPTION OF THE RELATED ART
Wireless communication devices, such as cellular telephones, are widely used as a replacement for conventional telephone systems. In addition to functioning as a replacement for a conventional telephone, wireless communication devices offer the advantage of portability, thus enabling the user to establish a wireless communication link between virtually any two locations on Earth.
The wireless communication device typically includes some form of display that provides the user with information, such as the destination telephone number for outgoing calls and caller ID for incoming calls. The destination telephone number may be entered manually by the user by activating a keypad on the wireless communication device. Alternatively, the user may select a prestored destination telephone number from a phone book storage area.
In a conventional display, the telephone numbers are shown on the display as a continuous string of digits with no separations for elements such as area codes, telephone exchanges, and the like. This results in difficulty in interpreting the data shown on the display. Therefore, it can be appreciated that there is a significant need for a system and method that will readily allow the user to interpret the data on a wireless communication device display. The present invention provides this and other advantages as will be apparent from the following figures and accompanying description.
SUMMARY OF THE INVENTION
The present invention is embodied in a system and method for providing visual user feedback in a wireless communication device. In one exemplary embodiment, the system includes a dialing plan storage area that contains data related to the dialing plan for the specific location (e.g., a country) of the user. A parser receives a number and applies the number digit by digit to the data contained within the dialing plan storage area. Based on the sequence of digits provided to the parser, a system can determine whether the number corresponds to a valid telephone number for the specified dialing plan. If the number does correspond to a valid telephone number, the parser applies a predetermined format for that telephone number and displays the number on a display with the appropriate formatting characters inserted between the digits. Typical formatting characters include: hyphen, parentheses, space, period and/or slash. If the number does not correspond to a valid telephone number, the system will not apply formatting characters to the number.
In an exemplary embodiment, the user manually enters the number via a keypad. Alternatively, the user may select a number from a phone book storage area or a call history storage area. The number may also be provided to the wireless communication device from a remote location. Numbers, such as caller ID, may be automatically provided to the parser. Similarly, numbers from remote locations may be included in a predetermined portion of a standardized message format. For example, a short messaging services (SMS) standard has a data portion preserved for a callback number. The system can automatically extract the callback number and provide it to the parser. In addition, a callback, or other telephone number may be provided within the SMS message. Again, the system can automatically extract the embedded number and provide it to the parser.
The data in the dialing plan storage area may be stored in the form of a data table. A portion of the data table is used as an index to a location within a parsing format storage area. The parsing format storage area may store parsing formats for a variety of different numbers, such as a local telephone number format, domestic long-distance telephone number format, international long-distance telephone number format, and the like. The formats in a parsing format storage area can correspond to conventional formatting characters used in the user's location. Alternatively, the user may edit the data in the parsing format storage area to personalize formatting character selection.
