`CELLULAR PHONEIPDA COMMUNICATION
`SYSTEM
`
`FIELD OF THE INVENTION
`
`This invention relates generally to an integrated cotnmu-
`nications system using a plurality of cellular PDNGPS
`phones for the management of a group of people through the
`use ofa communications net and. specifically. provide each
`user with a cellular phone that has features that permit all the
`users to know each other’s locations and status, to rapidly
`call and communicate data among the users by touching
`display screen symbols and to enable the users to easily
`access data concerning other users and other database infor—
`mation.
`
`DESCRIP’I'ION OF RELATED ART
`
`The purpose of a communications system is to transmit
`information bearing signals from a source, located at one
`point, to a user destination, located at another point some
`distance away. A conununications system is generally com—
`prised of three basic elements:
`transmitter.
`information
`channel and receiver. One form of communication in recent
`
`years is cellular phone telephony. A network of communi-
`cation cells sct up around an area such as the United States
`allows multiple users to talk to each other. either on indi-
`vidual calls or on group calls. Some cellular phone services
`enable a cellular phone to engage in conference calls with a
`small number of users. Furthermore, cellular conference
`calls can be established through 800 ntnnber services. Cel-
`ltllar telephony also now includes systems that
`include
`Global Positioning System (GPS) navigation that utilizes
`satellite navigation. These devices thus unite cellular phone
`cellular technology with navigation information and com—
`puter information transmission and receipt of data.
`Digital SMS (Smart Message Service] and TCI’r‘lP mes
`sages can be transmitted using cellular technology such as
`the various versions of GSM and CDMA or via a Wil': i local
`
`area network. One implementation of these GPS location
`reporting cellular systems is for the data to go to a central
`site where the infonnation is displayed for a person to
`monitor the locations of the units that have the combined
`
`GPS cellular phone. Another implementation permits the
`cellular phone users to also view the location of other GPS
`equipped units. A drawback of the current implementation is
`that these systems are either all on or all oil. There is no way
`to selectively activate participants or to stop the participants
`from participating in the network Another drawback of the
`use of the current combined cellular phone PDA technology
`is that when using the PDA to display a map (that also may
`depict georeferenced businesses, homes and other facilities’
`locations and phone numbers), and the operator wants to
`place a call, the cellular phonelPDA operator is required to
`obtain the phone number by touching the display screen at
`the correct location of that entity on the map to obtain the
`phone number, then the operator has to memorize the phone
`number, then go to a difi'erent display to enter the phone
`number, to make the call and then, if desired, go back to the
`map diSplay. Needless to say, this is a cumbersome process.
`Sending a text message to a location, business, home or
`facility that appears on a PDA map display to another
`cellular phone can also be a cumbersome process as the PDA
`operator has to find the phone number on the map display,
`memorize the phone number, then go to a different display
`to enter a text message, enter the text message, send the text
`message and then shift back to the map display program.
`

`
`Furthermore. for a phone to send data concerning a new
`entity of interest (car. person, tank. accident. or other entity]
`the operator must type in the information and the latitude
`and longitude of the entity.
`In spite of the rapid advance in cellular phone technology.
`it would also be desirable to actuate a remote cellular phone
`to annunciate an audio message to alert the remote user that
`there is an emergency (or for another reason) and that the
`calling cellular phone should be called immediately. l-‘ur—
`thermore. it would be desirable to cause the remote phone to
`display a text message, photograph, video clip or video
`transmission, to announce the caller‘s name and to be able
`to control a remote plume and cause the remote phone to call
`another phone number (as an example, to automatically
`establish an 800 number conference call].
`to vibrate. or
`increase the loudness of an annotuicemenl without any
`action by the remote phone operator.
`The present software invention overcomes many of these
`problems shown in the prior art by providing a cellular
`' phonelPDAlGPS user: a] the ability to selectively poll each
`of the other FDA/GPS phones to start reporting their posi—
`tions and status information directly to all or selected users
`equipped with cellular phonet'l’DA conununicationfGPS
`system in the communications net so that each of the
`systems that the data is transmitted to is provided a display
`of the location. status and other inflammation of the other

`users: b) the ability to exchange other entities of interest
`information and to assign these entities a category (car,
`person,
`tank, accident, or other entity) by touching the
`display screen at their locations on the map, and selecting
`the appropriate category switch; c) the ability to make rapid
`voice and data call initiation to locations, businesses, homes
`and facilities whose phone number is available in a georef—

`location on the FDA display and selecting the appropriate
`switch; and l] the ability to layer a suflicient number of

`U .3. Patent Application No. 200330 [39150 published Jul.
`24, 2003 shows a portable navigation and communication
`system. In one embodiment, the system combines within a
`single enclosure a GPS satellite positioning unit, mobile
`telephony using cellular phone technology and personal
`computing capable of wired or wireless internet or intranet
`access using a standard operating system. The purpose of
`this invention is to provide portable navigation for an
`individual. However, to operate the device, one still needs to
`utilize a keypad with the telephone functions. U.S. Patent

`
`SUMNIARY OF THE INVENTION
`
`A method and system employing cellular telephone com-
`munications to provide the location in limitation to a group
`of geographically dispersed people. and to enable the rapid
`transmission of data concealing entities of interest to the
`members of the group and to coordinate the activities of the
`group through data and voice conununications. Each of the
`cellular telephones includes a visual display with a touch
`screen. a global positioning system (GPS) receiver and
`navigation display. a CPU. melnory. power supply. battery.
`microphone. speaker and commercially available software.
`To this
`is added: a) communications data and voice
`exchange soltware, b) a map database and a database of
`geographically referenced fixed locations including military
`bases, homes. businesses. government facilities. street loca-
`tions and the like. each with a specified latitude and longi-
`tude. along with.
`if available. phone numbers that are
`associated with of each ol'these entities. c) another database
`with the constantly updated GPS location and status of all
`the software equipped cellular phonelPDAlGl’S systems
`that are part of the communications net.
`l'iaclt cellular phonelPlJNGPS system is identified on the
`display of the other phone systems by a symbol that is
`generated to indicate its identity. The symbol is placed at the
`correct geographical location and is correlated with the map
`on the display. Each cellular phonelPDNGPS System may
`enter other entities (locations of people. vehicles. buildings.
`facilities. and other entities) into its database. This informa—
`tion can be likewise transmitted to all the other participants
`on the communications net. The map. fixed entities. and
`cellular phonefPDAi‘GPS System conununications net par-
`ticipants‘ latitude and longitude information is related to the
`display it. y display locations by a mathematical correlation
`algorithm.
`When the cellular plionei’PDAlGPS System user uses his
`stylus or finger to touch one or more of the symbols or a
`location on the cellular phone display. the system’s software
`causes the status and latitude and longitude information
`concerning that symbol or location to be displayed.
`To operate the present invention. the operator (“cellular
`phone one“ or “phone one") starts the system by selecting
`the software which causes: a) the cellular phone to initiate (if
`it has not already been activated). b) the GPS interface to be
`established. c) a map of the geographic area where the
`operator is located and operator‘s own unit symbol to appear

`system selected item read otit area (which provides ampli-
`fication infonnation for the communications net participant
`or object that has been touched on the display screen) to
`appear on the display. f] an insert area that contains various
`varying data including: the list of net participants. a list of
`messages to be read. an indication of what portion of the
`map is being displayed in major area and other information
`to appear on the display. and g) a row of primary software
`created “soil switches” that are always present on the
`display. One of these soft switches when touched causes a
`matrix of software driven layered switches (soft switches) to
`appear on the display in place ofthe readout and insert areas.
`Some of these soft switches. when touched. cause the
`system‘s functions to occur. Other soft switches cause yet
`another layer of soft switches to appear. replacing those that
`were previously displayed. The operator is provided an
`indication of where the operator is in the layer of switches.
`and is able to return to the previous layer or to cause the
`layered switches to disappear and only the basic switches to
`remain. The operator can also use the phone’s hardware
`pointing device (Navigation Pad]
`to control
`the soft
`switches. By using these soft switches. and hard switches
`that are part of the cellular phone. the operator can activate
`difierent maps. change map scales. select which fixed enti-
`ties are desired to be displayed. display the information
`concerning the symbol the operator has touched. initiate
`phone voice calls, send messages (text. photographs and
`videos). enter symbols and information representative of
`other entities. view the locations and statuses of the other
`communications net participants. establish conference calls.
`pro-establish contcrence sub-nets that. when activated.
`cause all the phone numbers that are specified to be confer—
`enced for voice. text and photograph and video communi—
`cations. and transmit messages to remote phones which
`cause the remote phones to make calls. verbal announce-
`ments. vibrate. increase sound levels and other functions. To
`initialize the communications net. the cellular phone one
`operator selects. from a list. the other users (or all of them).
`that the operator desires to be part of the conununications
`net. The system then polls the selected phones to activate
`and become part of the communications net. The selected
`phones then transmit their positions to all the other phones
`in the established net. Through interaction with one or more
`other sollware enabled cellular phones, symbols are gener-
`ated on the operators’ displays based on the participants‘
`latitude and longitude that is exchanged between the cellular
`phones. The transmission of this information is based on an
`algorithm that considers time and or movement or upon a
`polling request. l'iach of the communication net symbols on
`the display represent a difl'erent cellular phone remote from
`cellular phone one. Each of the cellular phones has the
`phone numbers ofall the phones in the communications net
`in its database. Each of the phones also has in its database
`the pre—established phone numbers for the fixed locations:
`people. buildings. facilities. military bases. and other desired
`locations that can be called in its database. The touch screen
`
`provided with the LCD display in the cellular phone
`includes x. y coordinates that are correlated with the map on
`the cellular phone display and the geographic location ofthe
`fixed sites and the cellular phones in the conununications
`net. Each cellular phone can enter objects of interest by
`touching the display screen at the object’s location on the
`display screen map. The operator can then assign these
`objects a category (car. person.
`tank. accident, or other

`
`category). The latitude and longitude of these objects along
`with their category and other information is then sent on the
`communications network. Because each of the receiving
`telephone units has software that automatically converts the
`received data to the correct map location. the transmitted
`symbols appear at
`the correct location without operator
`intervention and their category information is available by
`touching the symbol on the display screen.
`Each cellular phonei'PDMGl’S has the conununications
`hardware along with the circuitry in sotlware to initiate a
`voice telephone call or transmit data messages. photographs.
`or videos by touching the screen with a stylus or linger at the
`symbol location displayed on the screen of the desired phone
`to be called and then selecting the “call" software switch on
`the display touch screen. The software will then cause the
`cellular phone to call to the specific phone number repre-
`sented by the symbol on the screen. This is done automati-
`cally. This action alleviates completely the necessity of
`actually looking up a phone number and manually entering
`the phone numbers required to make a cellular phone call.
`A fizrther benefit ofthe present invention is that more than
`one symbol can be specified to receive a cellular phone voice
`call and or data call. thus automatically conferencing them.
`The operator of the cellular phone can conference a small
`number of phones by touching the display screen locations
`of the communications net participant symbols that
`the
`operator wishes to conference by selecting a “conference"
`soft switch. This action will then cause the selected units to
`
`be conferenced together. The conference call can be
`expanded to a greater number of users by providing addi-
`tional software that would conference phones by sending a
`digital message to the remote celltllar phones from the
`operator cellular phone causing each of the remote cellular
`phones to dial a specified 800 conference call number and
`enter each individual phone participant code. The originator
`phone calls the same number and automatically enters the
`originator host code. Once all the phones have dialed the 800
`number and entered their appropriate participant and host
`numbers. the conference call will be established. Further-
`more. the operator of cellular phone one can pre-establish
`conference acts for voice and data exchange by either
`selecting them from a list or a table or by touching the
`display screen locations of the communication net partici—
`pant symbols that the operator wishes to conference and
`selecting a “conference net" soft switch. Once the operator
`has done that. the soliware associates those communication
`net participants as being part ofan established conference
`net. When the cellular phone operator chooses to call all the
`net participants. all the operator has to do is to select the
`designated software switch for that net to conference the
`pre-selected conference participants together. That action
`will then place a call to all the conferences without further
`action. This method of conference calling can be also used
`to send text messages. photographs and videos.
`Another embodiment of the invention can include a
`unique feature in which cellular phone one can send a digital
`message using SMS, TCPtIP or another protocol to another
`cellular phone on the communications net by touching a
`display screen symbol on the geographical screen and then
`selecting the appropriate soliware switch to transmit a
`digital message that would then remotely activate a program
`in the remote cellular phone to play a recorded audio file to
`announce an emergency and that a call to cellular phone one
`is required immediately. Since each of the remote cellular
`phones has the same software as cellular phone one and
`includes a PDA and the ability to receive digital messages.

`DETAILED DESCRIPTION
`
`Referring now to the drawings and. in particular. FIG. 1.
`the present invention is sltown generally at 10 that includes
`a small handheld cellular phonet'PDA conuttunications sys-
`tem itt housing 12 that includes an ordoll‘ power switch 19.
`a microphone 38. and art LCD display 16 that is also a touch
`screen system. The small area 16a is the Navigation Bar that
`depicts the telephone, GPS and other status data and the
`active software. With the touch screen system. the screen
`syntbols are entered through GPS inputs or by the operator
`using a stylus or finger 14 by ntanipulalively directing the
`stylus or finger 14 to literally touch display screen 16. The
`soft switches displayed on the screen are likewise activated
`by using a stylus or finger l4 and physically and manipu—
`latively directing the stylus or finger
`to literally touch
`display screen 16. The display x. y coordinates of the
`touched point are known by a C I’U in the PDA section of the
`communication systent that can coordinate various infonna-
`tion contained in the PDA portion relative to the x. y
`coordinate position on the screen. Inside housing 12 is
`contained the conventional cellular phone elements includ—
`ing a modem. a CPU for use with a PDA and associated
`circuitry connected to a speaker 24 and a microphone 38. A
`GPS navigational system that can determine the latitude and
`longitude ofthe cellular phone can be internal or extental to
`the housing 12. PDNCellular phone units such as these are
`currently on sale attd sold as a complete tntit (or with an
`external connected GPS) that can be used for cellular
`telephone calls and sending cellular SMS and 'lTil’llP or
`other messages using the PDA‘s display and computer. The
`GPS system is capable of determining the latitude and
`longitude and through SMS. TCPIIP. WiFi or other digital
`messaging software. to also transmit this latitude and [on-
`gitude information to other cellular phones via cellular
`comnuutications. \VIFi or radio. The unit includes a pair of
`cellular phone hardware activating buttons 20 to turn the
`cellular phone on and 22 to tout the cellular phone olT.
`Navigation l’ad actuator 18 is similar to ajoy or force stick
`in that the actuator 18 manually provides movement com-
`tttattds that can be used by the PDA‘s software to move a
`cursor. Switches 26 and 28 are designed to quickly select an
`operator specified software program. Device 24 is the sys—
`tem’s speaker. Device 38 is
`the system’s ttticropltottc.
`Switch 19 at the top left of the unit is the power on and
`power oil" switch.
`Tlte heart ofthe invention lies in the software applications
`provided in the system. Mounted inside housing 12 as part
`of the PDA is the display function screen and the CPU. The
`CPU includes databases that provide for a geographical tnap
`and georeferenced entities that is shown as display portion
`16b that includes as part of the display various areas of
`interest in the particular local ntap section.

`When looking at display 16. the software switches which
`appear at the very bottom of the display 16d are used to
`control many of the software driven functions of the phone.
`The soliware drawn and controlled switches are activated
`
`through the operator’s use of the Navigation Pad 18. or a
`small track ball. force stick or sitttilar hardware pointing
`device. Alternatively. the operator may chose to activate the
`software switch matrix by touching the screen with his
`finger or stylus at the switches' locations. When some of the
`software switches are activated. it will cause yet different
`software switches to appear. The bar display 16d shows the
`software switches “7M 1N. (zoom in)" “ZM OT (zoom
`out)", “(Tl'iN'l‘ (centcr]" “GRAB, (pattr'graby’ at the bottom
`of the screen. These software switches are for the operator
`to perform these functions. The “SWITI—I (switch)" software
`switch at
`the lower right causes the matrix of layered
`software switches to appear above the bottom row of
`switches. Through use of the software switches. one can also
`manipulate the geographical map or chart display. When
`looking at FIG. 1. permanent geographical locations and
`buildings are shown. For example.
`the police station is
`shown and when the symbol
`is touched by the stylus or
`finger. the latitude and longitude of the symbol‘s location. as
`shown in display section 16C“. is displayed at the bottom left
`of the screen. The bottom right side of display 16c is a
