`Systems and methods for locating a cellular phone are pro-
`vided. Moreparticularly, systems and methodsfor providing
`the location of a requested user’s cellular phone from a
`requesting user’s device (e.g., a secondcellular phone) based
`on access rights defined by the requested user. Location
`descriptions may be provided at a multitude of levels. For
`example,ifa cellular phone,or an identity associated to (e.g.,
`loggedinto) a cellular phone, has been given accessrights to
`acell phone’s exact location for an indefinite amount oftime,
`that cell phone can receive, on command,the exact location of
`the approvedcell phone. Other levels of location information
`that can be granted include, for example, proximities, states,
`and countries.

`APPLICATIONS
`
`This application is a continuation of U.S. patent applica-
`tion Ser. No. 10/400,196, filed on Mar. 25, 2003, which
`claims the benefit of U.S. Provisional Application No.
`60/367,967, filed on Mar. 25, 2002, both of which are incor-
`porated by reference herein in their entirety.
`
`BACKGROUND OF THE INVENTION
`
`This invention relates to systems and methodsfor deter-
`mining a device’s location. Moreparticularly, this invention
`relates to systems and methods for remotely determining a
`device’s location.
`
`The Global Positioning System (GPS) has been developed
`in which a ground-based system can receive GPS signals
`from satellites and determine its location based on the time
`
`that it takes the GPS signals to reach the ground-based sys-
`tem. Generally, three satellite signals are needed to determine
`where in the world a receiveris located (i.e., position trian-
`gulation).
`GPS systems have been integrated into cellular phones.
`However, these systems are deficient because the location of
`a device that is determined by these GPSsignals are only
`minimally utilized. It is therefore desirable to provide sys-
`tems and methods whichbetter utilize the information about
`a device’s location.
`
`SUMMARYOF THE INVENTION
`
`In accordance with the present invention, systems and
`methods are provided for locating cellular phones. Morepar-
`ticularly, the present invention provides systems and methods
`for allowing a user of a cellular phone(e.g., a requesting user
`or a requestor) to locate the position of a different user’s
`cellular phone(e.g., a requested user) based upon requestor-
`assigned accessrights.
`One object of the present invention is to provide a security
`feature which allows a user to limit and/or deny location
`access to a particularuser. In preferred embodiments,only the
`usersthat have been granted access to the location of a user’s
`cellular phone can actually locate that user’s cellular phone.
`Furthermore,different types of access levels may be provided
`that allow a userto filter location information to a different
`
`user. In this manner, a cell phone user may give access,
`through his or her cell phone, to a friend so that the friend can
`locate him or her dependent on the level of access that is
`granted to thatfriend.
`For example, suppose that Phil tells Bill that he will be
`shopping in Manhattan andthat Bill should locate him when
`Bill gets to Manhattan through their cell phones. In such an
`example, Phil may grant Bill access the exact location of his
`cell phone for a specific period of time (e.g., the next two
`hours). As a result, when Bill tries to access Phil’s location,
`Bill will be told exactly where in Manhattan Phil’s cell phone
`is located. Thus, Bill does not have to contact Phil directly to
`see where heis and, therefore, Phil does not have to spend any
`time giving Bill verbal directions; Bill can simply see what
`store Phil is currently in and goto it.
`As mentioned previously, levels in the scope of access may
`be controlled by a user such that, for example, only a user’s

`exact location, approximate location, city, state, or country
`can be accessed bya particular user.
`Location alerts and monitoring features are also provided.
`For example, Phil may give Jen, a resident of Pittsburgh,city
`access so that when Phil travels into Pittsburgh, Jen will be
`alerted of Phil’s presence. Such an alert may take the form of,
`for example, a display on Jen’s cell phone that communicates
`to Jen “Phil is in Pittsburgh.”
`Locating a cellular phone may be accomplishedin several
`ways. For example, satellite positioning systems such as the
`GlobalPositional System and the soon to be deployed Galileo
`system may beusedto locate a user’s cell phone.
`User positions and security settings may be regularly or
`manually transmitted to a remote system, such a remote data-
`base so that requesting users can locate a requested user’s
`position even if the requested user turns his/her cell phone
`OFF.Placing the security measures on a remote system (e.g.,
`remote database, computer, or server) provides an informa-
`tion brokering scheme such that the system is still operable
`even when cell phones are added, removed, or modified from
`the system.
`Additionally, the present invention may be configured to
`provide additional information aboutthe location of a user.
`Such additional information may be, for example, a map, a
`location marker on a map, a map that changes as the user
`moves, a compass, coordinates of the located cell phone,
`directions to the located cell phone, where a useris in relation
`to anotheruser, and information aboutthe location the located
`user is currently positioned in or nearby locations such as
`landmarks. Such information may be provided by a remote
`information provider (e.g., a remote map information pro-
`vider) and accessed by an information broker through a com-
`munications network.
`
`Manyother features are also employedthat realizes advan-
`tageous locating functionality. As per an example, suppose
`that a wife wants to see if her husbandhasleft work yet. She
`can locate her husband, without having to talk to him, and
`realize that he is driving home on a highway. Thus, a travel
`time option may beprovidedto the user. This option would
`compute the distance between the wife’s location and hus-
`band’s location by taking multiple location readings of the
`husband’s location to see how fast the husbandis traveling.
`Alternatively, because the husband’s position will map to a
`highway, the system may assumethatthe useris driving and
`may provide the wife with an estimate on the husband’s
`arrival time based on an assumed route. In this manner, the
`present invention may determine how muchtimeit will take
`the husbandto reach the wife and display this information to
`the wife.
`
`Asper other examples, a “see my friends” option mayalso
`be provided that brings up a map ofa desired area. Dots or
`symbols maybe present on the mapto signify the location of
`all user’s from which the requesting user has location infor-
`mation for. Similarly, a “find closest friend” option may be
`employed whichfindsthe closest user with whichthe request-
`ing user has location access to.
`Acell phone location may by accessedby a variety of other
`devices. Alternatively, a cell phone maybe usedto access the
`location of a variety of other devices. For example, ifthe wife
`wasat home, that wife may connectto the internet and access
`a remote databaseto either provide the most recent location
`information about the husband’s cell phoneto her or request
`a location update from the husband’s cell phone. The wife’s
`location may be already stored in such a database by associ-
`ating the location to the IP address of the computer or by a
`manualinput of the wife’s location. The wife’s identity may
`be determined by, for example, a login and password on a
`
`

`

`US 8,374,575 B2
`

`website. Thus, the above-identified security measures are not
`limited to device-to-device locating rather user to user locat-
`ing; the wife may only access the husband’s location if the
`husband has granted access for the wife to do so. If, by
`accident, the wife’s cell phone breaks, she may login on a
`friend’s cell phone and determine the husband’s location
`according to the device that the husbandis loggedinto.
`Security is preferably taken into account in the present
`invention and, therefore, location rights for a specific user
`may be given to a different user only by that specific user.
`However, a user may request location access rights from a
`different user. For example, a user may be provided with a
`request location screen on his cell phoneandthatuser(e.g.,
`user ““X”) may enter in the cell phone numberof the cell
`phone whose location is desired. The user associated to the
`FIG. 1 depicts a network topology of device location net-
`entered cell phone numbermaythenreceive an alert that says

`100 additional facilities and communication paths may be
`included. For example, a main facility (not shown in FIG.1)
`containing user location access rights may be included in

`mation directly from a positioning system or a cellular phone
`and then route this information to a cellular phone or posi-

`Positioning System (GPS)is used as the positioning system
`then GPSreceivers will be incorporated into cellular phones
`of the present invention. Persons skilled in the art will also
`appreciate that devices other than cellular phones may
`include positioning features. For example, watches, clothing,
`laptop computers, personaldigital assistants (PDAs), may all
`contain location systems(e.g., GPS) andutilize the security
`principles of the present invention to allow different user’s to
`access these locations.

`FIG. 2 showsflow chart 200 ofa simplified locating feature
`constructed in accordance with the principles of the present
`invention. Step 202 initiates when a user requests the location
`of another user’s cell phone. Step 206 evaluates if the user
`initiating the location request has the rights to access the
`location ofthe desired user. Ifno accessrights for the request-
`ing user have been granted then step 204 will preferably
`inform the requesting user that he/she has not been given
`access to the requested location. In this manner, every user
`may assign rights (e.g. govern the security) to whom may or
`may not locate him/her. In preferred embodiments, these
`rights will be stored in, or functionality executed from, a
`remote facility and accessed and utilized by a user’s cell
`phoneor other requesting device (e.g., a watch or PDA).
`If access has been given by a particularuser that allows for
`the requesting user to locate that particular user, step 208 is
`initiated and the allowed location information is provided to
`the user in step 210. Step 208 may optionally filter the loca-
`tion information such that only a portion information is
`passed to the requesting user. The requested user may have,
`
`

`

`US 8,374,575 B2
`
`5
`for example, defined that the requesting user only can obtain
`the city, state, or country ofhis/her location. Persons skilledin
`the art will appreciate that only the location ofthe desired user
`needs to have a cell phone or a positioning system. The
`requesting user may user other means(e.g., the internet) to
`request the location of the desired user.
`Personsskilled in the art will appreciate thatthe location of
`a user’s cell phone maybe retrieved, in step 208, from a
`remote database, facility, distribution center, or any other
`system. Moreparticularly, a remote database may periodi-
`cally request the location ofa cell phone user with a position-
`ing system andstore this information. This database mayalso
`keep a record of those people allowed to access that user’s
`location, the extent to which access is allowed, and the extent
`to which a user has requested a user’s location. A user may
`update, add, manipulate, or remove access at any time by
`doing so at this database. Thus, a requesting user only has to
`contact the remote database, have his/her identity recognized,
`have his/her access rights for the requested user location
`determined, and,if the requesting user has the correct access
`rights, be provided with the requested user’s location.
`Instead of a remote database periodically obtaining loca-
`tion information for a user, the database can obtain a user’s
`locations when a request is made for that user’s location,
`providing the requesting user has access to the requested
`user’s location. However, persons skilled in the art will rec-
`ognize that a remote database is utilized in the above
`examples that contains the locations, in most circumstances,
`of a multitude of users. Thus, to increase security even more,
`a requesting user’s cell phone maydirectly request a user’s
`location from the requested user’s cell phone without the
`need for a database. In such an example a user adds, manipu-
`lates, or removes access rights locally on his/her cell phone
`and does not have to worry aboutsecurity issues that surround
`placing his location on a remote database. Furthermore, in
`such an embodiment a user’s location does not have to be
