`
`[0001] This non-provisional application claims the benefit
`of the earlier filing date of, and contains subject matter
`related to that disclosed in, U.S. application Ser. No. 9/606,
`350 filed Jun. 29, 2000 having common inventorship, the

`
`BACKGROUND OF THE INVENTION
`
`[0002]
`
`1. Field of the Invention
`
`[0003] The present invention relates, generally, to the field
`of mobile communications and computer processing and
`more particularly,
`to a system, method, apparatus, and
`computer program product for providing location based
`services, mobile e-commerce, and other functions.
`
`[0004]
`
`2. Discussion of the Background
`
`[0005] Mobile phones and personal digital assistants
`(PDA) include functionality that
`is typically limited to
`providing a telephone communication link, which can be
`also sometimes used as a data communication link, and a set
`of software programs such as a calendar, email client,
`mini-browser, word processor, and other similar user appli-
`cations. Such devices therefore typically have limited func-
`tionality. Generally, very few of such devices include image
`input capabilities, voice recording capabilities, significant
`voice control capabilities, location determining or location
`based capabilities, or other capabilities described herein.
`
`In addition, portable devices are often carried with
`[0006]
`users who travel through cities, shopping complexes, and
`other facilities and geographical areas. However, currently
`portable devices do not provide users with many services
`and functions that are related to, or based on, the user’s
`location or changes in location. Similarly, while such
`devices often have capabilities for providing a telephone
`communication link, very few provide capabilities for pro-
`viding wireless Local Area Network (LAN), wireless Per-
`sonal Area Network (PAN), or any other wireless network
`communications. Furthermore, such devices typically do not
`include Web services capabilities or access thereto. As a
`result of these deficiencies and others, such devices fail to
`provide substantial mobile e-commerce services, location
`based functions, and functions or services available through
`the use of a wireless LAN.
`
`[0007] Furthermore, to date, venders have not been able to
`take advantage of location information associated with cus-
`tomers and potential customers or obtain information about
`prospective customers. Typically, a vender only identifies
`the customer, if at all, when the person makes a purchase.
`Consequently, venders are typically not aware of the nearby
`or approaching presence of a past customer, potential cus-
`tomer, or person seeking a product that the venderoffers. In
`addition, even if a vender had such information, venders
`have no mechanism in place for presenting advertisements
`to the person or otherwise enticing the user to visit the
`venderstore location or make a purchase. Furthermore, even
`if such a mechanism wasin place, the vender typically has
`
`no information about the person that can be used as a basis
`for selecting of an advertisement to be presented to the
`person or customizing the advertisement and the person has
`little incentive for viewing such an advertisement.
`
`[0008] These and other deficiencies are overcome by the
`present invention which provides a system, method, appa-
`ratus, and computer program product for providing location
`based services, location based mobile e-commerce, auto-
`mated processing, wireless network communications,
`mobile telephone communications, and many other func-
`tions and services described herein.
`
`SUMMARYOF THE INVENTION
`
`[0009] The primary object of the present invention is to
`overcomethe deficienciesof the prior art described above by
`providing a system, method, apparatus, and computer pro-
`gram product for providing location services and mobile
`e-commerce.
`
`[0010] Another key object of the present invention is to
`provide a system, method, apparatus, and computer program
`product for providing automated processing and mobile
`e-commerce.
`
`{0011] Yet another key object of the present inventionis to
`provide a system, method, apparatus, and computer program
`product for providing mobile capabilities, and functions not
`available on existing mobile devices.
`
`{0012] Another key object of the present invention is to
`provide a system, method, apparatus, and computer program
`product for facilitating localized e-commerce such as in a
`localized auction, shopping complex, vender store location,
`or other facility or geographical area.
`
`[0013] Another object of the present invention is to pro-
`vide a system, method, apparatus, and computer program
`product that can facilitate commercial exchanges through
`the use of wireless communications.
`
`[0014] One embodimentof the present invention achieves
`these objects and others by providing a system, method,
`apparatus and computer program product for providing
`location based functions and mobile e-commerce compris-
`ing a central processing unit including a processor, a storage
`device, and programming stored in the storage device, a
`display device, an audio input device, an audio output
`device, a communications module, and a location module.
`
`[0015] The programming controls the operation of the
`present invention to provide functions based on location
`data,
`to facilitate commercial exchanges by wirelessly
`exchanging paymentand product information with venders,
`to identify services such as venders meeting selection cri-
`teria, to wirelessly exchange select information with other
`users and systems, to restrict and/or monitor the use of the
`device based on user provided parameters, selecting one of
`a plurality networks through which to communicate, trig-
`gering an action based on a change in location and sensed
`data, storing a voice annotation with computer data file,
`determining service providers and associated communica-
`tion parameters, contemporaneously maintaining a wireless
`voice and data link, and many other functions and services
`that are described herein.
`
`[0016] Further features and advantages of the present
`invention, as well as the structure and operation of various
`

`to digital signals at the source, or at an intermediate system,
`and transmitted to the device 101 as a digital signal through
`a wireless communication link. At reception, the signals are
`processed and presented to the user (e.g., via RealPlayer
`Media Player®) as is well knownto those skilled in the art.
`Thus,
`the device 101 includes software for formatting,
`processing, and providing a representation of the signal to
`the display for presentation to the user. The device 101 may
`also optionally include an analog signal receiver(e.g., tuner,
`amplifier, etc.) for receiving and presenting analog radio
`signals directly.
`
`[0046] The device 101 receives the digital signals from a
`remote receiver (e.g.,
`through a wireless PAN from an
`automobile or in XM transmission), which provides the
`signal
`in digital form to the device 101, for immediate
`presentation or storage (e.g., as an MP3file or an MPEG-4
`formatted television broadcast). Furthermore,
`the remote
`receiver(e.g., in an automobile) may receive and store the
`data (e.g., in MP3 format) and transmit the stored data to the
`device 101 upon request by the user.
`
`[0047] The following descriptions of various networks,
`standards, formats and protocols are well-known in the art,
`are provided as a matter convenience, and are not meantto
`be interpreted as a limitation on the communications capa-
`bilities of a device of the present invention. As discussed,
`technology for using any mobile phone network, WLAN,or
`PAN that is suitable for desired application(s) may be used.
`Communication with the wireless networks is accomplished
`through access points that receive and transmit wireless
`signals as is knownin the art. Each access pointis preferably
`individually addressable by a computer system (e.g., a
`client-server computer system)—which may be a vender
`computer system or facility computer system—with whichit
`communicates data.
`
`[0048] Preferably the device 101 includes a short range
`wireless LAN module (a PAN module) for communicating
`via a Bluetooth® network. The Bluetooth® wireless speci-
`fication includes layer and application layer definitions and
`supports data, voice and content-centric applications. As is
`knownin the art, devices that comply with the Bluetooth®
`
`wireless specification operate in the unlicensed, 2.4 GHz
`radio spectrum ensuring communication compatibility
`worldwide. The devices use a spread spectrum, frequency
`hopping, full-duplex signal at up to 1600 hops/sec. The
`signal hops among 79 frequencies at 1 MHzintervals to give
`a high degree of interference immunity and up to seven
`simultaneous connections can established and maintained.
`
`[0049] The short range wireless LAN module (e.g., the
`Bluetooth® module) or PAN module allows the device 101
`to wireless communicate with printers, wirelessly exchange
`payment information, communicate with automobile com-
`puter systems, building computers systems, facility com-
`puter systems, point of sale (POS) devices, vender computer
`systems, and with other devices employing the present
`invention. In addition,
`the PAN module can be used to
`communicate across a WLAN or WWAN.
`
`[0050] Preferably, the device 101 complies with the Blue-
`tooth® Hands-Free profile and imaging profile specifica-
`tions. The Hands-Free profile enables hands-free use of
`mobile phones in automobiles and the imaging profile
`facilitates transmitting digital images over mobile devices.
`More specifically, the Hands-Free profile allows automatic
`establishment of a connection between the automobile’s
`hands-free system and a mobile device the user brings into
`the automobile. The Imaging profile allows digital images to
`be shared among mobile devices. For example, a digital
`camera can share content with a mobile phone, personal
`computer or other handheld or be sent directly to a printer
`equipped with Bluetooth® wireless technology.
`
`[0051] As is knownin the art, Bluetooth® enabled devices
`include a link controller that identifies other Bluetooth®
`devices, coordinates a connection with such devices, and
`facilitates sending and receiving data from such devices. In
`establishing a connection with another Bluetooth® enabled
`device (e.g., a printer, computer, another device, etc.) the
`two devices first exchange a unique global identification
`code (global ID), which indicates the devices’ profiles and
`capabilities. If the device profiles match, a connection is
`made. If the device profiles do not match, the devices ignore
`each other. The profiles include sets of protocols and pro-
`cedures that define device functionality and identity such as
`headset, printer, PDA,cell phone, pager,etc.
`
`[0052] After two devices establish a connection, oneis set
`as the master and the other becomesa slave. The connection
`of two or more Bluetooth enabled devices is creates a PAN
`
`called a piconet in whichall the devices in the same piconet
`are synchronized to the same hopping scheme determined by
`the master. As is known inthe art, a Bluetooth® piconet can
`include up to 255 parked slaves (devicesthat are not actively
`receiving or sending data), which can be unparked by the
`master as needed. Devices in range of the piconet, but not
`connectto the piconet, are referred to as being in a stand by
`mode.
`
`[0053] Bluetooth® compatible devices can be designed to
`have varying distances of communication capability. Con-
`sequently, Bluetooth® access points, which form part of a
`larger WLAN,a WAN,orother network can bestrategically
`positioned so that communication is limited to devices
`within a predetermined and/or selected distance and/or
`direction. The Bluetooth® Specification v.1.1, including the
`Core Specification (Volume I) and Profile Definitions (Vol-
`umeII), is hereby incorporated by reference.

`
`[0054] As an alternate or in addition to Bluetooth tech-
`nology, the device 101 may include hardware and software
`for communicating via the Echnonet standard.
`
`[0055] The device 101 preferably also includes a WLAN
`module for communicating via a wireless local area network
`(WLAN), which are commonly used for corporate or Inter-
`net communications on campusesor enterprises. More pref-
`erably,
`the WLAN module is Wi-Fi (short for wireless
`fidelity) compatible, which meansthat is compliant with the
`TEEE 802.11b specification, which is DSSS—(direct
`sequence spread spectrum) compatible and has a communi-
`cation range of approximately 1,000 feet in open areas and
`250 to 400 feet in closed areas. Specifications for WLAN in
`Europe include HiperLAN2 (High Performance Radio
`LAN), which mayalternately be used.
`
`[0056] As discussed, the device 101 may also include a
`WWAN module. WWANs are commonly is used to link
`cities, states or large enterprises. One commonprotocol for
`this type of network is 802.1la. The IEEE (Institute for
`Electrical and Electronics Engineers) 802.11 standard
`(802.11, 802.11a, 802.11b, and 802.11b) is hereby incorpo-
`rated by reference.
`
`[0057] Preferably, the device 101 includes hardware and
`software for communicating with, or through, a third gen-
`eration (3G) network, which is embodies some, orall, of the
`in IMT-2000 standard established by the International Tele-
`communications Union (ITU) or Universal Mobile Telecom-
`munication System (UMTS). The preferred 3G network
`standard requires support for data packet networking (i.e.,
`packet switched networking) and includes “always on”
`connection capabilities connection (or in other words an
`instant connection) and which allows the device 101 to
`receive incoming transmissions as they are sent. Networks
`employing at least some of the 3G standard include CDMA-
`2000 based services (e.g., CDMA 1XRTT, CDMA 2000
`1XEV) (CDMArefers to Code-Division Multiple Access),
`FOMA(Freedom of Mobile Multimedia Access), and Wide-
`band CDMA.
`
`[0058] Alternately, or in addition, the device 101 of the
`present invention is designed to communicate via a two and
`a half generation (2.5G) network, which is also a packet-
`switched network
