METHOD OF PROVIDING A CELLULAR PHONE/PDA COMMUNICATION SYSTEM
` DESCRIPTION
`
`Field of the Invention
`[(Para 1]) 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 featuressoftware 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
`[(Para 2]) 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 cellssystems 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 conference calls with a small number of users. Furthermore, cellular conference
`calls can be established through 800 number services. Cellular 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, computer information transmission and receipt of data.
`[(Para 3]) Digital SMS (Smart Message Service (SMS) and TCP/IP messages can be
`transmitted using cellular technology such as the various versions of GSM and CDMA or via a
`
`

`

`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 GPS cellular GPS
`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 off. There is no way to selectively activate participants or
`to stop the participants from participating in the
`
`
`
`
`Page 3 of 46
`
`

`

`
`network Another drawback of theor 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 is that whenhas drawbacks when calling. When an operator
`makes a cellular phone call using the PDA to display a map (that also may depict
`georeferencedgeo-referenced businesses, homes and other facilities' locations and
`phone numbers), and the operator wants to place a call, the cellular phone/PDA
`operator is required to obtaindisplay the numeric phone number by touching the display
`screen at the correct location of that entity on the map to obtain, memorize the numeric
`phone number, then the operator has to memorize the phone number, then go
`toand 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.
`
`In spite of the rapid advance in cellular phone technology, it
`[Para 4]
`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. Furthermore, 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 phone 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 announcement without any action by the
`remote phone operator.
`[Para 5]
`The present software invention overcomes many of these
`problems shown in the prior art by providing a cellular phone /PDA/GPS
`user: a) the ability to selectively poll each of the other PDA / GPS phones to
`
`Page 4 of
`
`
`

`

`
`start reporting their positions and status information directly to all or
`selected users equipped with cellular phone/PDA communication/GPS
`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
`information 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 georeferenced
`database including the cellular phone/PDA/GPS systems in a
`communications net by touching the display screen at the appropriate
`location on the PDA display and selecting a call switch; d) the ability to make
`rapid voice and data conference call initiation to locations, businesses,
`homes and facilities whose phone
`
`
`
`Page 5 of

`
`

`

`
`number is available in a georeferenced database including the cellular
`phone/PDA/GPS systems in a communications net by touching the display
`screen at the appropriate locations on the PDA display and selecting a
`conference call switch; e) the ability to remotely control from one cellular
`phone/PDA/GPS any of the other cellular phone/PDA/GPS systems phones
`including the ability to control remote cellular phones to make verbal
`prerecorded announcements, place return calls, place calls to another
`phone number, vibrate, execute text to speech software, change sound
`intensity and process and display information by touching the display
`screen at their location on the PDA display and selecting the appropriate
`switch; and f) the ability to layer a sufficient number of switches or buttons
`on the PDA display to perform the above functions without overlaying the
`map.
`[(Para 6]4) U.S. Patent Application No. 2003/0139150 published July 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 Application No. 2003/0139150
`described a wireless communication system operating the PDA in a conventional manner.

`is no provision to cause other similarly equipped cellular phone/PDA users to transmit their
`locationlocations. 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 participant's 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
`participant(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 announcements,
`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.

`
`A method and system employing cellular telephone
`[Para 7]
`communications to provide the location information to a group of
`geographically dispersed people, and to enable the rapid transmission of
`data concerning entities of interest to the members of the group and to
`coordinate the activities of the group through data and
`
`
`

`

`

`
`voice communications. Each of the cellular telephones includes a visual
`display with a touch screen, a global positioning system (GPS) receiver and
`navigation display, a CPU, memory, power supply, battery, microphone,
`speaker and commercially available software. To this is added: a)
`communications data and voice exchange software, b) a map database and
`a database of geographically referenced fixed locations including military
`bases, homes, businesses, government facilities, street locations and the
`like, each with a specified latitude and longitude, along with, if available,
`phone numbers that are associated with of each of these entities, c) another
`database with the constantly updated GPS location and status of all the
`software equipped cellular phone/PDA/GPS systems that are part of the
`communications net.
`[Para 8] Each cellular phone/PDA/GPS 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 phone/PDA/GPS
`System may enter other entities (locations of people, vehicles, buildings,
`facilities, and other entities) into its database. This information can be
`likewise transmitted to all the other participants on the communications
`net. The map, fixed entities, and cellular phone/PDA/GPS System
`communications net participants' latitude and longitude information is
`related to the display x, y display locations by a mathematical correlation
`algorithm.
`[Para 9] When the cellular phone/PDA/GPS 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.
`[Para 10]
`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 at the correct
`latitude and longitude on the map, d) the locations of people, vehicles,
`buildings, and the like that are part of the database appear as symbols on the
`map, e) the system selected item read out area (which provides amplification
`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 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
`
`Page 9 of

`
`

`

`
`g) a row of primary software created "soft 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 of the 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
`
`
`
`Page 10 of
`
`
`

`

`
`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
`different maps, change map scales, select which fixed entities 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, pre-establish conference sub-nets
`that, when activated, cause all the phone numbers that are specified to be
`conferenced for voice, text and photograph and video communications, and
`transmit messages to remote phones which cause the remote phones to
`make calls, verbal announcements, 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 communications 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 software enabled cellular phones, symbols are generated 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. Each of the communication net symbols on the
`display represent a different cellular phone remote from cellular phone one.
`Each of the cellular phones has the phone numbers of all 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 of the fixed sites and
`the cellular phones in the communications 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
`
`Page 11 of
`
`
`

`

`
`at the correct location without operator intervention and their category
`information is available by touching the symbol on the display screen.
`[Para 11]
`Each cellular phone / PDA/ GPS has the communications
`hardware along with the circuitry in software to initiate a voice telephone
`call or transmit data messages, photographs, or videos by touching the
`screen with a stylus or finger at the
`
`
`
`Page 12 of
`
`
`

`

`
`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 represented by the symbol on the screen. This is done
`automatically. 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.
`[Para 12] A further benefit of the 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
`additional software that would conference phones by sending a digital
`message to the remote cellular 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. Furthermore, the operator of cellular phone one can
`preestablish conference nets 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 participant symbols that the operator wishes to
`conference and selecting a "conference net" soft switch. Once the operator
`has done that, the software associates those communication net
`participants as being part of an 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 preselected 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.
`[Para 13] Another embodiment of the invention can include a unique feature
`in which cellular phone one can send a digital message using SMS, TCP/IP 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 software switch to transmit a digital message that
`would then remotely activate a program in the remote cellular phone to play
`
`Page 13 of
`
`
`

`

`
`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, the ability to control remote cellular
`phones to make verbal announcements, display images, place return calls,
`place calls to another
`

`

`
`available in a geo-referenced database including the cellular phone/PDA/GPS devices
`in a communications net by touching the display screen at the appropriate map
`location on the PDA map display and selecting a call switch; e) the ability to make
`rapid voice, and conference call initiation to locations, businesses, homes and
`facilities whose phone numbers are available in a geo-referenced database including
`the cellular phone/PDA/GPS devices in a communications net by touching the display
`screen at the appropriate other user locations on the PDA map display and selecting a
`conference call switch; f) the ability to access a facility's URL or to automatically fill in
`their E-mail address; g) the ability to remotely control from one cellular
`phone/PDA/GPS any of the other cellular phone/PDA/GPS systems phones including
`the ability to control remote cellular phones to make verbal prerecorded
`announcements, place return calls, place calls to another phone number, vibrate,
`execute text to speech software, change sound intensity, remotely control software
`and functions resident on the remote phone and process and display information by
`touching the display screen at their location on the PDA display and selecting the
`appropriate switch; and g) the ability to layer a sufficient number of switches or
`buttons on the PDA display to perform the above functions without overlaying the
`map.
`phone number, vibrate, change sound intensity and process and display
`pre-stored data, images and video can be achieved.
`[Para 14]
`In accordance with the present invention, a multiple cellular
`phone communication network is set up using the invention. Each cellular
`phone contains the same software and circuitry that includes cellular phone
`technology, GPS navigation technology, and a PDA for displaying maps,
`georeferenced symbols, and data concerning symbols of interest and
`software created soft switches, transmitting and receiving digital SMS,
`TCP/IP and other protocol messages. To establish each other's
`communication net IP addresses, the cellular phones first exchange SMS
`messages (or use another method) that identifies their IP addresses. Each
`phone then transmits to all others its location and status in accordance with
`an established algorithm that is based on time and or movement. Each
`cellular phone is also able to poll the other cellular phones to transmit their
`locations. Each user is able to transmit to all the other users: text messages,
`photographs and videos. Using the present invention, a cellular telephone
`network can be set up in which all of the parties in the network have almost
`automatic and instant access to and status of any and all other parties in
`Page 15 of
`
`
`
`

`

`
`the network by touching the display screen symbol of the party he desires
`to initiate voice and data calls, thus, instantly activating the calls. This is an
`immense time saver in dealing with a cellular phone network for all the
`parties combined.
`[(Para 15]6)
`It is an object of this invention to provide an improved cellular telephone
`communication network among a plurality of cellular phones for greatly increasing the
`call up and initiation speed ofdecreasing the operator actions necessary to
`establish calling and conferencing between each of the cellular phones with each
`other.

`
`PREFERRED EMBODIMENT OF THE INVENTION
`
`[(Para 27]21)
`Referring now to the drawings and, in particular, Figure 1, the present
`invention is shown generally at 10 that includes a small handheld cellular phone/PDA
`communications system 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 Barnavigation 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 information
`useful in the communication network. The CPU also includes a symbol generator for
`creating touch screen display symbols discussed herein. With the touch screen
`system16, the screen symbols are entered through GPS inputs or by the operator using a
`stylus or finger 14 (or operator finger) by manipulatively directing the stylus or finger 14
`to literally touch display screen 16. The soft switches 16d displayed on the screendisplay
`16 are likewise activated by using a stylus or finger 14 and physically and manipulatively
`directing the stylus or finger to literally touch display screen 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 information contained in the
`PDA portion relative to the x, y coordinate position on the screendisplay 16. Inside housing
`12 is contained the conventional cellular phone elements
`
`
`
`
`Page 20 of 46
`
`

`

`
`including a modem, a CPU for use with a PDA and associated circuitry connected to a
`speaker 24 and a microphone 38. A GPS navigational systemreceiver 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
`
`
`
`Page 21 of
`
`
`

`

`
`communication network via cellular communications, WiFi or radio. The unitdevice 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 Padpad actuator 18 is similar to a joy or
`force stick in that the actuator 18 manually provides movement 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. DeviceSpeaker 24 is the
`system's speaker. Device 38 is the system's microphoneand microphone 38
`are used for audio messages. Switch 19 at the top left of the unitdevice 10 is the power
`on and power off switch for the entire device.
`[(Para 28]22)
`The heart of the invention lies in the AGIS software applications provided in
`the systemdevice. Mounted insidewithin housing 12 as part of the PDA is the display
`function screen16 and the CPU. The internal CPU includes databases that provide for a
`geographical 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.
`
`[(Para 29]23) 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 operator's use of the Navigation Padnavigation pad
`18, or a small trac
