`ABSTRACT
`A method and system includes the ability for individuals to
`set up an ad hoc digital and voice network easily and rapidly
`to allow users to coordinate their activities by eliminating the
`need for pre-entry of data into a web or identifYing others by
`name, phone numbers or email. This method is especially
`useful for police, fire fighters, military, first responders or
`other emergency situations for coordinating different organi(cid:173)
`zations at the scene of a disaster to elevate conventional
`communication problems either up and down the chain of
`command or cross communication between different emer(cid:173)
`gency units. The method and system provides that the users
`are only required to enter a specific Server IP address and an
`ad hoc event name, a password and perhaps the name of the
`particular unit.

`
`BACKGROUND OF THE INVENTION
`
`1. Field of the Invention
`A communications method and system using a plurality of
`cellular phones each having an integrated Personal Digital
`Assistant (PDA) and Global Positioning System (GPS)
`receiver for the management of two or more people through
`the use of a communications network. The method and sys(cid:173)
`tem provide each user with an integrated handheld cellularl
`PDAlGPS/phone that has Advanced Communication Soft(cid:173)
`ware application programs (hereinafter referred to as ACS) 40
`and databases used in conjunction with a remote Server that
`enable a user to quickly establish a communication network
`of cell phone participants having a common temporary ad hoc
`network using mobile wireless communication devices.
`The invention includes a method and communication sys- 45
`tem to quickly set up and provide ad hoc, password protected,
`digital and voice networks to allow a group of people to be
`able to set up a network easily and rapidly, especially in an
`emergency situation.
`2. Description of Related Art
`The purpose of a communications system is to transmit
`digital messages from a source, located at one point, to user
`destination( s), located at otherpoint(s) some distance away. A
`communications system is generally comprised of three basic
`elements: transmitter, information chaunel and receiver. One 55
`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 60
`phone to engage in conference calls with a small number of
`users. Furthermore, cellular conference calls can be estab(cid:173)
`lished through 800 number services. Cellular telephony also
`now includes systems that include GPS navigation that uti(cid:173)
`lizes satellite navigation. These devices thus unite cellular 65
`phone technology with navigation information, computer
`information transmission and receipt of data.
`
`2
`The method and operation of communication devices used
`herein are described in U.S. Pat. No. 7,031,728 which is
`hereby incorporated by reference and U.S. Pat. No. 7,630,
`724.
`Military, first responder, and other public and private emer(cid:173)
`gency groups need to be able to set up ad hoc digital and voice
`networks easily and rapidly. These private networks may be
`temporary or longer lasting in nature. The users need to be
`able to rapidly coordinate their activities eliminating the need
`10 for pre-entry of data into a web and or identifYing others by
`name, phone numbers or email addresses so that all intended
`participants that enter the agreed ad hoc network name and
`password are both digitally and voice intercounected. When a
`user or users leave the network, no data concerning the net-
`15 work participants need be retained.
`Coordinating different organizations at the scene of a
`disaster presents several problems as there are voice and
`digital data (text messages) communications that need to be
`constantly occurring up and down the chain of command. As
`20 an example, communications are required from a police chief
`to a police captain to a police lieutenant to a police sergeant to
`a policeman and then back up the same chain of command.
`Digital data exchange of GPS data or other means provides
`the location component of the units. Digital chat, text mes-
`25 sages, white boards and photo video exchange provide exten(cid:173)
`sive collaboration. However, during a disaster, other first
`responders such as fire departments must become engaged.
`While the fire department users may have voice and digital
`data (text messages) communications up and down their
`30 chain of command, these individuals do not have the ability to
`cross communicate necessarily with police units without a
`substantial degree of immediate coordination. The method
`and system in accordance with the present invention
`described herein discloses how digital communications along
`35 with Personal Computer (PC) and PDA devices can be used to
`quickly establish user specific password protected private ad
`hoc voice and data networks to enable both data and voice
`communications up and down their chain of command and
`simultaneously with different, not pre-known, organizations
`responding to a disaster. The invention defines a method of
`accomplishing this by providing all persounel that need to
`communicate with each other with a PC or PDA which are
`interconnected to a Server using cellular or other communi-
`cations.
`
`SUMMARY OF THE INVENTION
`
`Applicant's communication system and method described
`herein is embodied in the Advanced Communication Soft-
`50 ware (ACS) application programs developed by applicant and
`installed in the integrated PDAlGPS cell phones used herein
`and remote Servers.
`A plurality of Internet Protocol (IP) capable PDAlGPS
`devices each havingACS application programs and databases
`provides a communication network in conjunction with a
`remote Server that provides the ability to: a) establish an ad
`hoc network of devices so that the devices can either broad(cid:173)
`cast to a group or selectively transmit to each of the other;
`each PDAlGPS phone starts by requesting access to the
`Server and identifYing a mutually agreed to network name
`and password and once granted, reports its GPS position and
`status; the Server then routes the data to all signed on network
`participants so that each of the devices exchange location,
`status and other information; (b) force the received informa(cid:173)
`tion to the recipient's display and enable the recipient to
`acquire additional information by touching the display screen
`at a remote phone's location on the PDA display; (c) make

`the users and stores their IP addresses in the Server. Thus the
`Server has all the users IP addresses stored and can pass
`location and status information among the ad hoc network
`participants even though the network participants have not
`entered other network participants' names, phone numbers or
`email addresses. Thus one of the purposes of the invention is
`to allow an ad hoc network to be formed on a temporary basis
`in a rapid marmer.
`When using the PTT feature, the ACS can enable the net-
`work participant to: 1. PTT with all that are in the ad hoc
`digital network, or 2. PTT with select specific network par(cid:173)
`ticipants, by touching their symbol(s) and then selecting PTT
`soft switch or 3. Specify a group of the network participants
`by assigning their symbols or unit names to a list of network
`participants and then associating the list with a soft switch
`whose function is to enable the operator to have PTT com-
`munications with all in the list.
`Since only one person is transmitting on a PTT voice
`network at any given time, the receiving network partici(cid:173)
`pant's ACS can relate the PTT IP address to the IP address of
`the unit transmitting his identification on the digital ad hoc
`network. This information can then be used by the other PTT
`networked participant's ACS to: 1. flash the transmitting
`unit's name on their PDAIPC screens or 2. if a photograph has
`25 been attached to the ad hoc digital network symbol of the PTT
`transmitting person, to flash that photograph on the receiving
`unit's PDAIPC display.
`It is an object of this invention to enable each participant in
`the communication network to join other ad hoc network
`30 participants to form an ad hoc digital and voice network with
`other cell phone users rapidly for coordinating member
`activities.
`In accordance with these and other objects which will
`become apparent hereinafter, the instant invention will now
`be described with particular reference to the accompanying
`drawings.

`calls to or send data to remote phones by touching their
`display symbols and selecting the appropriate soft switch; (d)
`layer a sufficient number of soft switches or buttons on the
`PDA display to perfonn the above functions without overlay(cid:173)
`ing the map; and (e) allow a polling mode in each cell phone
`that pennits a user to contact other cell phone users that have
`a common interest or relationship with a password and iden(cid:173)
`tifier for communication and to establish quickly a temporary
`ad hoc network especially in an emergency.
`A communication Server acts as a forwarder for IP com- 10
`munications between any combination of cell phone/PDA
`users and/or PC based users. Network participant location,
`identity and status messages are sent to the Server by each
`user. Network participant entered tracks are also sent to the
`Server. Because this network participant location and track 15
`data is of interest to all the network participants, the Server
`forwards the data received from one participant to all other
`participants, causing their displays automatically, without
`any operator action, to display the received information, thus
`providing the information necessary for all network partici- 20
`pants to know the identity, location and status of all other
`network participants.
`The Server also acts as a forwarder of data addressed from
`one participant to one or more addressed participants, thus
`permitting the transmission of free text, prefonnatted mes(cid:173)
`sages, photographs, video, Email and Uniform Resource
`Locator CURL) data from one network participant to other
`selected network participants.
`The above functions can also be accomplished using peer
`to peer WiFi, WiMax or other peer to peer communications.
`However, for use with cellular communications and to assure
`the level of security that cell phone companies require, a
`centralized static IP routable Server is used.
`The IP Server also fills another role of being a database
`from which data can be requested by network participants 35
`(i.e. maps, satellite images, and the like) or can be pushed to
`network participants (i.e. symbology and soft switch
`changes, and the like). The Server is used to establish an ad
`hoc network within certain groups using an ad hoc event name
`and password.
`This invention provides a method and a system establish(cid:173)
`ing an ad hoc password protected digital and voice network
`that can be temporarily set up or longer lasting in nature. The
`invention described herein allows users to rapidly coordinate
`their activities without having to pre-enter data into a web or 45
`identify others by name, Email addresses or phone numbers.
`Essentially the users that establish the ad hoc and password
`protected digital and voice networks are required to enter the
`Server's IP address and an ad hoc event name and a password.
`In the case of military and first responders, the name of the 50
`user's unit may also be used. This action causes the specific
`PDA or PC of the user to commence reporting directly to the
`Server's IP address. Once the Server receives the initial IP
`message from the user's PDA or PC, the server can com(cid:173)
`mence to exchange data with the user's PDA or Pc. The initial
`IP message may also contain additional data such as a license
`number and, if desired, a phone number manually entered or
`automatically acquired by the ACS. The IP address of the
`PDA and PC unit sending the initial IP message is stored by
`the Server. The Server then responds with a message notifY(cid:173)
`ing the user that his PC/PDA is connected to the Server. The
`user PDAIPC then reports its GPS location and other status
`information directly to the Server. This information is
`retained by the Server even when there are no other devices
`initially communicating with the Server. When the other 65
`user's devices sign on to the Server with the same ad hoc event
`name and password, the Server software then recognizes all
