`
`METHOD OF PROVIDING A CELLULAR
`PHONEAPDA COMMUNICATION SYSTEM
`
`FIELD OF THE INVENTION
`0001. This invention relates generally to an integrated
`communications system using a plurality of cellular/PDA/
`GPS phones for the management of a group of people
`through the use of a communications net and, specifically, to
`provide each user with a cellular/PDA/GPS/phone that has
`Software application programs and databases that permit all
`the users to continuously know each other's locations and
`status, to rapidly call and communicate voice, high speed
`internet data, photographs and video clips among the users
`by touching display screen symbols and to enable the users
`to easily access data concerning other users and other
`database information.
`
`DESCRIPTION OF RELATED ART
`0002 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 communications system is generally
`comprised of three basic elements: transmitter, information
`channel and receiver. One form of communication in recent
`years is cellular phone telephony. A network of cellular
`communication systems set up around an area Such as the
`United States allows multiple users to talk to each other,
`either on individual calls or on group calls. Some cellular
`phone services enable a cellular phone to engage in confer
`ence calls with a small number of users. Furthermore,
`cellular conference calls can be established through 800
`number services. Cellular telephony also now includes sys
`tems that include Global Positioning System (GPS) naviga
`tion that utilizes satellite navigation. These devices thus
`unite cellular phone technology with navigation informa
`tion, computer information transmission and receipt of data.
`0003 Digital Smart Message Service (SMS) and TCP/IP
`messages can be transmitted using cellular technology Such
`as various versions of GSM and CDMA or via a WiFi local
`area network. One implementation of these GPS location
`reporting cellular systems is for the data to go to a remote
`central site where the information is displayed for a person
`to monitor the locations of the cellular units that have the
`combined cellular GPS phone. Another implementation per
`mits the cellular phone users to also view the location of
`other GPS equipped units. A drawback of the current imple
`mentation is that these systems are either all on or all off.
`There is no way to selectively activate participants or to stop
`the participants from participating in the network or for
`participants to set their reporting intervals that is based on
`time or distance traveled. The use of the current combined
`cellular phone/PDA technology has drawbacks when call
`ing. When an operator makes a cellular phone call using the
`PDA to display a map (that also may depict geo-referenced
`businesses, homes and other facilities locations and phone
`numbers), the cellular phone/PDA operator is required to
`display the numeric phone number by touching the display
`screen at the correct location of that entity on the map.
`memorize the numeric phone number, and select a different
`display to physically 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 or an email to a location, business, home or
`
`facility that appears on a PDA map display or to another
`cellular phone can also be a cumbersome process as the PDA
`operator has to find the phone number or email address of
`the location on the map display, memorize the phone number
`or email address, 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, not
`currently on the geo-referenced map display (car, person,
`tank, accident, or other entity), the operator must type in the
`information and the latitude and longitude of the new entity
`of interest.
`0004 U.S. Patent Application No. 2003/0139150 pub
`lished Jul. 24, 2003 shows a portable navigation and com
`munication system. In one embodiment, the system com
`bines 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 Application No. 2003/0139150 described a wireless
`communication system operating the PDA in a conventional
`manner. There is no provision for displaying the location of
`other similarly equipped systems. There is no provision to
`cause other similarly equipped cellular phone/PDA users to
`transmit their locations. There is no provision for entering
`other entities of interest by touching the display screen at
`their locations on a map. There is no provision for making
`a telephone call by touching the display Screen at a net
`participants symbol or entered facility (police station, fire
`station, etc.) symbol to initiate automatically the telephone
`call to that user or by touching multiple symbols to make
`conference calls. There is no provision for sending text
`messages, photographs or videos by touching the net par
`ticipant(s) symbol(s) on the display screen to automatically
`send text messages, photographs or videos to that participant
`or participants. There is no provision to go to a facility's web
`site or to automatically fill in a facility's E-mail address.
`There is no description or disclosure of a procedure to cause
`digital messages to be sent to a remote cellular phone that
`would cause the cellular phone to make Verbal announce
`ments, increase Sound intensity, vibrate or to call back or to
`call another phone number. There is no description of the
`uses of layered soft switches which confine the switches to
`a particular vicinity of the PDA’s display screen.
`SUMMARY OF THE INVENTION

`
`PREFERRED EMBODIMENT OF THE
`INVENTION
`Referring now to the drawings and, in particular,
`0021
`FIG. 1, the present invention is shown generally at 10 that
`includes a small handheld cellular phone that includes a
`personal digital assistant (PDA) and a global positioning
`system receiver (GPS) communications device in housing
`12 that includes an on/off power switch 19, a microphone 38,
`and an 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.
`AGIS software refers to the application software used in this
`invention. AGIS is a trademark of AGIS Corporation. Each
`cell phone includes a CPU and databases that store infor
`mation useful in the communication network. The CPU also
`includes a symbol generator for creating touch screen dis
`play symbols discussed herein. With the touch screen 16, the
`screen symbols are entered through GPS inputs or by the
`operator using a stylus 14 (or operator finger) by manipu
`latively directing the stylus 14 to literally touch display 16.
`The soft switches 16d displayed on the display 16 are
`likewise activated by using a stylus 14 and physically and
`manipulatively directing the stylus to literally touch display
`16. The display x, y coordinates of the touched point are
`known by a CPU in the PDA section of the communication
`system in housing 12 that can coordinate various informa
`
`

`

`US 2006/01996 12 A1
`
`Sep. 7, 2006
`
`tion contained in the PDA portion relative to the x, y
`coordinate position on the display 16. 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 speaker 24 and microphone 38. A GPS
`navigational receiver that receives signals from satellites
`that can determine the latitude and longitude of the cellular
`phone housing 12 can be internal or external to the housing
`12. PDA/cellular phone units such as these are currently on
`sale and sold as a complete unit (or with an external
`connected GPS) that can be used for cellular telephone calls
`and sending cellular SMS and TCP/IP or other messages
`using the PDA's display 16 and computer (CPU). The GPS
`system including a receiver in housing 12 is capable of
`determining the latitude and longitude and through SMS,
`TCP/IP, WiFi or other digital messaging software, to also
`transmit this latitude and longitude information of housing
`12 to other cellular phones in the communication network
`via cellular communications, WiFi or radio. The device 10
`includes a pair of cellular phone hardware activating buttons
`20 to turn the cellular phone on and 22 to turn the cellular
`phone off. Navigation pad actuator 18 is similar to a joy or
`force stick in that the actuator 18 manually provides move
`ment commands that can be used by the PDA’s software to
`move a cursor on display 16. Switches 26 and 28 are
`designed to quickly select an operator specified Software
`program. Speaker 24 and microphone 38 are used for audio
`messages. Switch 19 at the top left of device 10 is the power
`on and power off switch for the entire device.
`0022. The heart of the invention lies in the AGIS software
`applications provided in the device. Mounted within housing
`12 as part of the PDA is the display 16 and the CPU. The
`internal CPU includes databases that provide for a geo
`graphical map 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 map section.
`0023. When looking at display 16, the software switches
`(soft switches) which appear at the very bottom of the
`display 16d are used to control by touch many of the
`software driven functions of the cellular phone and PDA.
`The software drawn and controlled switches are activated
`through the operators use of the navigation pad 18, or a
`small track ball, force stick or similar hardware display
`cursor pointing device. Alternatively, the operator may
`choose to activate the software Switch matrix by touching
`the screen with a stylus 14 (or finger) at the switches 16d
`locations. When some of the software switches are activated,
`different software switches appear. The bar display 16d
`shows the software switches “ZM IN (zoom in),”“ZM OT
`(Zoom out),”“CENT (center) and “GRAB (pan/grab) at
`the bottom of the screen. These software switches are for the
`operator to perform these functions. The “SWITH (switch)
`software switch at the lower right causes a matrix of layered
`software switches (soft switches) to appear above the bottom
`row of switches. Through use of the software switches, the
`operator can also manipulate the geographical map 16b or
`chart display. When looking at FIG. 1, permanent geo
`graphical 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
`symbols 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 multifunction inset area that can
`contain a variety of information including: a) a list of the
`
`Case 2:22-cv-00263-JRG-RSP Document 122-7 Filed 09/07/23 Page 11 of 22 PageID #:
`9594
`
`communication link participants; b) a list of received mes
`sages; c) a map, aerial photograph or satellite image with an
`indication of the Zoom and offset location of the main map
`display, which is indicated by a square that depicts the area
`actually displayed in the main geographical screen 16b; d)
`applicable status information; and e) a list of the commu
`nication net participants. Each participant user would have
`a device 10 shown in FIG. 1.
`0024. Also shown on the display screen 16, specifically
`the geographical display 16b, is a pair of different looking
`symbols 30 and 34, a small triangle and a small square,
`which are not labeled. These symbols 30 and 34 can
`represent communication net participants having cellular
`phones in the displayed geographical area that are part of the
`overall cellular phone communications net having the same
`device 10 used in this invention. The latitude and longitude
`of symbol 30 is associated within a database along with a
`specific phone number and, if available, its IP address and
`email address. The screen display 16b, which is a touch
`screen, provides x and y coordinates of the screen 16b to the
`CPU's software from a map in a geographical database. The
`Software has an algorithm that relates the X and y coordinates
`to latitude and longitude and can access a communications
`net participant’s symbol or a fixed or movable entity's
`symbol as being the one closest to that point.
`0025 For describing the network, the operator's phone is
`cellular phone “one.” In order to initiate a telephone call to
`the cellular phone user (communication net participant)
`represented by symbol (triangle) 30 at a specific latitude and
`longitude display on chart 16b, the operator touches the
`triangle 30 symbol with the stylus 14. The operator then
`touches a “call software switch from a matrix of displayed
`soft switches that would overlay the display area 16c.
`Immediately, the cellular phone will initiate a cellular tele
`phone call to the cellular phone user at the geographical
`location shown that represents symbol 30. A second cellular
`phone user (communication net participant) is represented
`by symbol 34 which is a small square (but could be any
`shape or icon) to represent an individual cellular phone
`device in the display area. The ring 32 around symbol 30
`indicates that the symbol 30 has been touched and that a
`telephone call can be initiated by touching the soft switch
`that says “call.” When this is done, the telephone call is
`initiated. Other types of symbolic elements on the display 16
`can indicate that a cellular phone call is in effect. Addition
`ally, the operator can touch both symbol 34 and symbol 30
`and can activate a conference call between the two cellular
`phones and users represented by symbols 30 and 34. Again,
`a symbolic ring around symbol 34 indicates that a call has
`been initiated.
`0026.
`Equally important, the operator of cellular phone
`“one' can call the police station or any other specific
`geographical facility displayed on the map, including:
`(buildings, locations of people, vehicles, facilities, restau
`rants, etc., (whose cellular phone numbers and, if available,
`E-mail addresses, IP addresses and their URLs were previ
`ously stored in the database) by touching a specific facility
`location on the map display using the stylus 14 and then
`touching the cellular phone call Switch. As an example, the
`operator can touch and point to call a restaurant using a soft
`Switch by touching the restaurant location with his stylus
`and then touching the call soft switch. The cellular phone
`will then call the restaurant. Thus, using the present inven

`tion, each participant can touch and point to call to one or
`more other net participants symbolically displayed on the
`map each of whom have a device as shown in FIG. 1 and
`can also point to call facilities that had been previously
`stored in the phone's database. Furthermore, this symbol
`hooking and Soft Switch technique can be used to go to a
`fixed facility's website or to automatically enter the fixed
`facility's E-mail address in an e-mail.
`0027) Each cellular phone/PDA/GPS user device is iden
`tified on the map display of the other participant user phone
`devices by a display symbol that is generated on each user
`phone display to indicate each user's identity. Each symbol
`is placed at the correct geographical location on the user
`display and is correlated with the map on the display. The
`operator of each cellular phone/PDA/GPS device may also
`enter one or more other fixed entities (buildings, facilities,
`restaurants, police stations, etc. and geo-referenced events
`Such as fires, accidents, etc.) into its database. This infor
`mation can be likewise transmitted to all the other partici
`pants on the communications net. The map, fixed entities,
`events and cellular phone/PDA/GPS device communication
`net participants latitude and longitude information is related
`to the 'x' and “y” location on the touch screen display map
`by a mathematical correlation algorithm.
`0028. When the cellular phone/PDA/GPS device user
`uses a stylus or finger to touch one or more of the symbols
`or a location displayed on the cellular phone map display,
`the system's software causes the status and latitude and
`longitude information concerning that symbol or location to
`be displayed. In order to hook a symbol or “track' such as
`another net participant which represents an entity on the
`geo-referenced map display, or a fixed geographical entity
`Such as a restaurant, police station or a new entity observed
`by a cell phone user which is discussed below, the operator
`points at or near the location of a geo-referenced symbol
`appearing on the cellular phone/PDA display that represents
`a specific track or specific participant or other entity. The
`hook application Software determines that the stylus is
`pointed close to or at the location of the symbol and puts a
`circle, square or other indication around the symbol indi
`cating that amplification information concerning the track is
`to be displayed and indicating that additional data or change
`in data can be made to the indicated symbol. The hook
`application code then sends a message to the display appli
`cation code to display the net participant, facility or entity's
`amplifying data. The display application code retrieves the
`primary data and amplification data concerning the track or
`entity from the database and displays the information at the
`correct screen location. The operator can then read the
`amplification data that relates to that specific symbol at the
`specific location. The cellphone operator can also select soft
`Switches on the touch screen display to change the primary
`data and amplification data or to take actions which could
`include making cellular phone calls, conference calls, 800
`number calls, sending a free text message, operator selected
`preformatted messages, photographs or videos to the hooked
`symbol or to drop the symbol.
`0029. Each known net participant has a cellular phone
`number, IP address and, if available, E-mail address that is
`stored in each participant’s device database.
`0030 To use the present invention, the operator (“cellular
`phone one' or “phone one') starts the PDA/cellular phone

`device system by selecting the Software which causes: a) the
`cellular phone to be activated (if it has not already been
`activated), b) the GPS interface receiver to be established, c)
`a map of the geographic area where the operator is located
`and operator's own unit symbol to appear at the correct
`latitude and longitude on the map on the display, d) the
`locations of fixed facilities such as restaurants, hotels, fire
`departments, police stations, and military barracks, that are
`part of the database to appear as symbols on the map, e) the
`device selected item read out area (which provides ampli
`fication information 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
`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 “soft
`Switches' that are always present on the display to appear.
`0031. For point to call network units and fixed facilities,
`the application code detects the x, y display screen location
`of the symbol that is designated by the user's stylus and
`translates the x, y coordinates to latitude and longitude and
`then: (1) searches the database to find the symbol at that
`location, (2) places a “hook' indicator (a circle, square or
`other shape) around the symbol, (3) displays any amplify
