`This invention relates to mobile stations in a radio

`the functions of a mobile telephone while transmitting,

`stations

`Heretofore,
`there has not been a self—contained mobile
`
`station capable of operating as a mobile telephone while
`
`performing these more advanced functions in a convenient
`
`manner. An existing solution has been to use a portable
`
`computer such as a laptop or Notepad, such as the Newton
`
`Notepad from Apple Computer, which is connected to a
`
`mobile telephone so that text and images can be displayed.
`There are several problems,
`however, with this

`around the laptop or Notepad computer in addition to the
`
`subscriber's mobile telephone. This is inconvenient at
`
`best, and for some subscribers, or in some circumstances,
`it is not possible.
`Second,
`the subscriber must possess
`the knowledge required to connect
`the portable computer
`to the mobile
`telephone.

`this knowledge. Third,
`the subscriber must take time to

`the portable computer to the mobile telephone.
`connect
`this is inconvenient at best, and may result in
`Again,
`increased cost to the subscriber since a call is either
`lengthened by the time it takes the subscriber to connect
`the computer and the telephone, or two calls must be
`placed:
`a first call to alert the subscriber that text
`or images are to be sent, and a second call to send the
`text or images.
`
`Although there are no known prior art teachings of
`solution
`to
`the
`aforementioned
`deficiency
`and
`a
`shortcoming such as that disclosed herein, a number of
`prior art references exist
`that discuss subject matter
`that bears some relation to matters discussed herein.
`Such prior art references are U.s. Patent Number 5,348,347
`to Shink, a publication titled "Searching for the Perfect
`PDA", and a publication titled "Is it a phone or a PDA?
`Here's what Simon says".
`Each of
`these references is
`discussed briefly below.
`
`a serial port for connecting to a desktop computer or
`
`U.S. Patent Number 5,348,347 to Shink discloses a
`pocketbook size organizer
`that
`can store a portable
`cellular telephone.
`The organizer comprises a flexible
`book that may hold a mobile telephone, a notepad, a pen,
`a calculator, and a timer. However, Shink does not teach
`
`or suggest a personal Communications terminal which can
`perform as
`a mobile
`telephone while
`transmitting,
`receiving, and displaying text or image data.
`
`The publication titled "Searching for the Perfect
`PDA" describes
`three generations of personal digital
`assistants (PDAs).
`The first generation comprised palmtop
`or handheld computers.
`These palmtops were generally
`pocket sized with a split case and a hinge on the spine.
`One side of the palmtop held a display, and the other side
`held a keyboard. External communication was limited to

`When used as a PDA rather than a telephone,
`the device may
`display one of two on—screen keyboards or a numeric keypad

`This creates a

`
`The second generation of PDAs was much
`
`like the first generation, but added the capability to
`recognize handwriting entered with a stylus on the display
`screen.
`The third generation of PDAs are often called

`
`"Is it a phone or a PDA?
`
`Here's what Simon says" is a journal article appearing in
`the October 31, 1994 issue of InfoWorld magazine at pages
`119—120.
`The article describes the Simon as a device
`
`comprising a cellular telephone and a personal digital
`assistant
`(PDA).
`The device may function as a mobile
`
`telephone as well as offering communications features such
`
`as electronic mail

`Almost all of one side of the Simon device is a LCD

`The on—screen keyboard also creates a third
`
`disadvantage because a very limited amount of display area
`remains for displaying text or graphics information when

`
`this solution is not suitable for interactive
`
`programs or programming.
`
`An additional disadvantage of the Simon device is its
`
`exposed display screen which covers virtually all of one
`side of the device and is therefore extremely vulnerable
`to impact damage. Great care must be taken when utilizing
`the Simon device, and this is not always practical when
`when utilizing a mobile station.
`
`It would be a distinct advantage to have a personal
`communications terminal that overcomes the above-mentioned
`disadvantages.
`Such.
`a
`terminal would have the full
`capabilities of a personal computer,
`a keyboard large
`enough for manual data entry without the use of a stylus,
`and
`a display screen with enough usable
`area
`for
`interactive programming.
`In addition,
`the display screen
`would be mounted in a protected location allowing full use
`of the terminal in a rugged mobile environment.
`
`Review of each of the foregoing references reveals
`
`no disclosure or suggestion of a system or method such as
`
`that described and claimed herein.

`functional unit
`
`31, a telephone functional unit 32, a modem 33, a mobile
`
`data-interface (MDI) unit 34, and a PDA Open sensor 35.

`include, for example,
`telephone numbers entered on the PDA

`
`A connecting circuit
`

`
`electronically
`
`connects the PDA unit 31,
`
`the telephone unit 32,
`
`the
`

`
`the MDI unit 34, and the PDA Open sensor 35.
`
`Two power
`
`supply units
`
`(batteries)
`
`36
`
`and 37
`
`supply
`
`electrical power to the PCT.
`
`The batteries are located
`
`in the bottom half 22 of the PCT which includes the PDA
`
`keyboard 24. This configuration provides a low center of
`
`gravity and stability to the PCT 10.
`
`A high power supply
`
`36 provides high power to the wireless telephone unit 32
`
`and the PDA unit 31.
`
`A low power supply 37 provides a
`

`
`PCT/SE96/00992
`
`power supply 36 is detached from the unit for charging or
`when its energy level is low.
`Power to the PDA unit 31
`is turned OFF when the PCT 10 is in the closed position.
`Power may still be supplied to the telephone unit 32 in
`the closed position if the telephone unit is in use.
`Other components of the PDA unit 31 include a read
`only memory (ROM) 41 for storing application programs and
`providing limited operations of
`the
`PDA unit when
`operating off the low power supply 37.
`The PDA unit also
`includes a random access memory (RAM) 42 for storing data,
`the PDA display screen 23,
`the PDA keyboard 24,
`a PDA
`central processing unit
`(CPU)
`43 which may
`be
`a
`microprocessor
`for timing and control of
`the PDA,
`accumulator/register 44 contained within the PDA CPU 43,
`various input/output
`ports 45,
`and a hard drive
`memory device 46.
`The I/O ports 45 send and receive data
`from, for example,
`the mobile data interface 34,
`the modem
`33,
`the PDA Open sensor 35,
`and external
`sources of
`application software programs 47 and data which may be
`loaded onto the hard drive memory 46.
`The hard drive
`memory device 46 stores application software programs and
`data,
`and provides
`the PDA unit with full personal
`computer capabilities.
`The hard drive is powered from the
`high power source 36.

`
`When electrical power from the power supplies exceeds
`the minimum power level required for operation of the hard
`drive,
`the PDA unit 31 may utilize the hard drive to
`access application software programs stored there. This
`capability,
`combined with the PDA's full alpha-numeric
`keyboard 24 and PDA screen 23, make
`the PDA a fully
`functional personal notepad computer. Telephone (PHONE)
`and facsimile (FAX)
`functions are also performed and may
`be indicated with icons shown on the PDA screen 23 or as
`selections on a pull—down menu. When electrical power
`from the power supplies is less than the minimum power
`level required for operation of the hard drive,

`
`The process begins at step 61 where the PCT

`to the telephone unit
`is ON,

`
`process moves to step 63 where normal wireless telephone
`functions are enabled.
`If, however, it is determined at
`
`step 62 that power is not ON to the telephone unit,

`then
`
`the process moves to step 64 where the process stops and

`If power is not
`ON to the PDA unit 31,
`then the process moves to step 66
`where it is determined whether or not power is ON to the
`telephone unit 32.
`If it is determined at step 66 that
`power is not ON to the telephone unit,
`then the process
`returns
`to step 64 where
`the process
`stops
`and no
`functions are enabled.
`If, however,
`it is determined at
`step 66 that power is ON to the telephone unit,
`then the
`process moves to step 67 where normal wireless telephone
`functions are enabled, and the PDA keyboard 24 is enabled
`for entering telephone numbers.
`
`Returning to step 65, if the power is ON to the PDA
`unit 31,
`then the process moves to step 68 where it is
`determined whether or not power is ON to the telephone
`unit 32.
`If it is determined at step 68 that power is ON
`to the telephone unit,
`then the process moves to step 69
