`
`BACKGROUND OF THE INVENTION
`
`A. Field of the Invention
`
`This invention relates to the field of wireless telecommunications. More
`
`particularly, this invention relates to a wireless intelligent personal server that receives
`
`data transmitted over a wireless communications channel and automatically processes it
`
`so as to maintain a copy of at least one electronic file stored in a source computer.
`
`B. Description of Related Art
`
`A typical modem office uses a number of different databases of information that
`
`i= :~
`
`~=~10
`
`are frequently updated. Examples of such databases include schedules, contact lists,
`
`i=i
`
`i~=
`
`price lists, real estate lists, and incoming e-mails. Such databases are typically stored as
`
`electronic files on either an office-wide server or on individual personal computers
`
`located in the office space. Typically, individual workers in the office space are able to
`
`use personal computers, usually with network connections, to access the databases. More
`
`particularly, the personal computers typically run applications that retrieve the desired
`
`information from the databases and display it to the user. With this configuration, the
`
`most up-to-date versions of the databases are typically available to the individual
`
`workers, even though the electronic database files are frequently updated.
`
`However, many workers often work outside of the office environment at least one
`
`2O
`
`day per week, and, typically, it is more difficult to gain access to the most up-to-date
`
`versions of important electronic files when outside of the office environment. A
`
`currently used solution is to use portable computers to "dial in" to the office network
`
`using the PSTN, Intemet, or other wireline networks. However, mobile workers do not
`
`Page 6 of 398
`
`

`
`always have access to wireline connections at all desired times. Accordingly, wireless
`
`communications systems have been developed by which mobile workers can aeeess their
`
`office databases even without a wireline connection. As an example, some wireless
`
`telephones are able to send and receive limited amounts of data using the wireless
`
`application protocol (WAP).
`
`However, most of these wireless communications approaches, including the WAP
`
`approach, use a "pull" methodology, whereby the user first requests the information and
`
`then waits for a response. This "pull" methodology has the disadvantage of high latency
`
`and, typically, high cost. The high latency arises from the delay that typically occurs in
`
`each step of the process of retrieving the desired information. In particular, there is the
`
`time spent entering the keystrokes needed to make the request, the airtime spent
`
`transmitting the request, the delay in having the request reaching the office network
`
`through intermediate networks, the delay in having the office network search through its
`
`::= 5
`
`!:= ~i
`
`databases to formulate a response, and the delay in transmitting the response through the
`
`intermediate networks and then over the air interface. The high latency is not only
`
`troublesome to the user; it leads to high costs due to the airtime needed to process the
`
`request and the response.
`
`The problem becomes more acute the more interactive the transaction becomes.
`
`A user using WAP to retrieve a new e-mail message with an attachment provides a
`
`20
`
`simple illustration of the problem. First, the user requests the new e-mail message and
`
`receives it after waiting for the latency period described above, for which the user is
`
`typically charged airtime. Second, the user reads the new e-mail message and sees that it
`
`has an attachment. Then the user must make another request to receive the attachment.
`
`Page 7 of 398
`
`

`
`The user waits for another latency period to receive it, thereby typically incurring
`
`additional airtime charges. Moreover, the latency period may be quite long, because files
`
`attached to e-mails are often quite large. Accordingly, existing "pull" approaches, such
`
`as WAP have substantial disadvantages.
`
`5
`
`Another problem with many technologies for receiving data over wireless
`
`channels is that they are highly device-specific, i.e., they are based on providing wireless
`
`functionality to existing devices, such as specific models of personal digital assistants
`
`(PDAs). However, there are a number of problems with device-specific approaches.
`
`First, many people use different computing devices at different times, so that providing
`
`only one of the user’s computing devices with wireless functionality is, at best, only a
`
`partial solution. Second, different computing devices differ in their abilities to handle
`
`different types of data. For example, desktop PCs typically have much more memory
`
`than PDAs, and desktop PCs often have access to high quality monitors, speakers, and
`
`peripherals to display information and provide functionality to the user in ways that are
`
`! = ii
`
`unavailable to typical PDAs. On the other hand, PDAs also have many advantages over a
`
`desktop PC, such as portability. In addition to the availability of different hardware,
`
`different computing devices may have different operating systems and applications
`
`available to them. Accordingly, approaches that provide wireless functionality only to
`
`specific devices have substantial disadvantages.
`
`2o
`
`For example, Kaufman, U.S. Patent No. 6,034,621, discloses systems and
`
`methods for communicating changes made to a data file on a personal computer (PC) to a
`
`personal digital assistant (PDA). In accordance with some of the disclosed embodiments,
`
`when the data file on the PC is changed, synchronization information is transmitted over
`
`Page 8 of 398
`
`

`
`a paging network to a pager that is connected to the PDA, such as by a serial or parallel
`
`connection. A synchronization routine in the PDA then interacts with the
`
`synchronization information output from the pager to update the data file in the PDA.
`
`While potentially reducing the latency problem, at least for small amounts of data,
`
`the Kaufman approach suffers from a number of disadvantages. First, PDAs are not
`
`typically on all of the time. Thus, update information may be missed because of the PDA
`
`being off. Second, PDAs typically have a very limited memory, i.e., 8 megabytes or less.
`
`Because of this limited memory, mobile workers may not be able to access some of the
`
`very large electronic files that they can access at their offices.

`
`SUMMARY OF THE INVENTION
`
`In a first principal aspect, the present invention provides a wireless intelligent
`
`personal server that comprises a radio frequency (RF) receiver for receiving downstream
`
`data transmitted over a wireless communications channel, a memory, a central processing
`
`unit (CPU), a set of embedded machine language instructions that are executable by the
`
`CPU for processing the downstream data to provide at least one electronic file in the
`
`memory, and a first interface for allowing an external display device to access the at least
`
`one electronic file.
`
`In a second principal aspect, the present invention provides a wireless data
`
`communication system that comprises a wireless intelligent personal server and a
`
`wireless telephone in communication with the wireless intelligent personal server. The
`
`wireless intelligent personal server includes a memory and a radio frequency (RF)
`
`receiver. The RF receiver receives downstream data transmitted over a first wireless
`
`communications channel, and the wireless intelligent personal server processes the
`
`downstream data to provide at least one electronic file in the memory. The wireless
`
`telephone transmits an acknowledgement over a second wireless communications
`
`i:i
`
`: = 5
`
`channel when the wireless intelligent personal server receives the downstream data.
`
`In a third principal aspect, the present invention provides a wireless data display
`
`system that comprises a wireless intelligent personal server and a display device in
`
`2O
`
`communication with the wireless intelligent personal server. The wireless intelligent
`
`personal server includes a memory and a radio frequency (RF) receiver. The RF receiver
`
`receives downstream data transmitted over a wireless communications channel, and the
`
`wireless intelligent personal server processes the downstream data to provide at least one
`
`Page 10 of 398
`
`

`
`electronic file. The display device has at least one application that accesses the at least
`
`one electronic file to display information to a user.
`
`In a fourth principal aspect, the present invention provides a method for updating
`
`a target electronic file to reflect changes made to a source electronic file. In accordance
`
`with the method, the target electronic file is stored in a wireless intelligent personal
`
`server. The wireless intelligent personal server receives downstream data transmitted
`
`over a wireless communications channel. The downstream data reflects changes made to
`
`the source electronic file. The wireless intelligent personal server automatically updates
`
`the target electronic file with the downstream data to provide an updated electronic file.
`
`A display device is brought into communication with the wireless intelligent personal
`
`server, and the display device accesses the updated electronic file.
`
`In a fifth principal aspect, the present invention provides a method for creating,
`
`without user intervention, an electronic file on a wireless intelligent personal server. In
`
`accordance with the method, the wireless intelligent personal server receives downstream
`
`i:;. !J 15
`
`data transmitted over a wireless communications channel. The wireless intelligent
`
`personal server automatically creates the electronic file from the downstream data. A
`
`display device is brought into communication with the wireless intelligent personal
`
`server, and the display device accesses the electronic file.

`
`DETAILED DESCRIPTION OF THE INVENTION
`
`Figure 1 is a functional block diagram of a wireless communication system 10 in
`
`~ :i¸
`
`accordance with an exemplary embodiment of the present invention. System 10 includes
`
`an enterprise information technology (IT) system 12, which typically includes a plurality
`
`of computers and other devices networked together to provide computing and
`
`information technology services for a business or other organization. As shown in Figure
`
`1, one or more personal computers, such as personal computer (PC) 14, are connected to
`
`enterprise IT system 12. Enterprise IT system 12 may also have access to a centralized
`
`database for the enterprise, such as enterprise database 16, as shown
`
`in Figure 1.
`
`2O
`
`Enterprise IT system 12 may be located entirely within one office area,
`
`or it may be
`
`distributed over various remote locations.
`
`System 10 also includes a first wireless network 20 and a second wireless network
`
`22.
`
`First wireless network 20 is able to transmit data, at least intermittently, over one or
`
`Page 12 of 398
`
`

`
`more downstream wireless channels to wireless receivers operating within its wireless
`
`coverage area. Preferably, first wireless network 20 uses subcarriers of fi’equency
`
`modulated (FM) radio transmissions and/or televisions transmissions to provide the
`
`downstream wireless channels. Most preferably, the subcarriers used by first wireless
`
`5 network 20 are modulated using orthogonal frequency division multiplexing (ODFM) in
`
`order to minimize multipath effects, such as fading and distortion, and to increase data
`
`throughput. Alternatively, first wireless network 20 may be a one-way paging network,
`
`which may use the FLEXTM protocol of Motorola, Inc., a two-way paging network, which
`
`may use the REFLEXTM protocol of Motorola, Inc., or it may wirelessly transmit data by
`
`some other means.
`
`Second wireless network 22 is preferably a cellular or PCS network that provides
`
`two-way wireless communications, in a format, such as AMPS, TDMA, CDMA, or
`
`GSM, for wireless telephones, such as wireless telephone 24. Thus, with reference to
`
`Figure 1, wireless telephone 24 is able to transmit to wireless network 22 over an
`
`upstream channel 26 and is able to receive from wireless network 22 using a downstream
`
`channel 27.
`
`An intermediate network 28 is connected to first wireless network 20 and to
`
`second wireless network 22, and enterprise IT system 12 uses a wireless network
`
`management system 29 to communicate with wireless networks 20 and 22, via
`
`20
`
`intermediate network 28. Intermediate network 28 maybe any wide-area network (WAN)
`
`or local-area network (LAN) capable of transmitting digital data between enterprise IT
`
`system 12 and wireless networks 20 and 22. Preferably, intermediate network 28 is either
`
`the Internet or a private corporate network.
`
`Page 13 of 398
`
`

`
`A wireless intelligent personal server (WIPS) 30 is able to receive data wirelessly
`
`transmitted by first wireless network 20. When WIPS 30 receives data transmitted by
`
`wireless network 20, WIPS 30 stores it in its memory, as described in more detail below.
`
`WIPS 30 is able to transfer the data stored in its memory to and from different types of
`
`display devices 32, on at least an intermittent basis, as indicated by the dotted line in
`
`Figure 1. WIPS 30 may also be able to transfer data from its memory to and from
`
`wireless telephone 24 on at least an intermittent basis, as indicated by the dotted line in
`
`Figure 1.
`
`Display device 32 is a device that has a user interface for displaying the data
`
`~::{i lo
`
`!:-
`
`stored in WIPS 30. More particularly, display device 32 typically runs one or more
`
`applications to access the data stored in WIPS 30 and to display it to the user. The
`
`applications on display device 32 may also allow the user to modify the data stored in
`
`WIPS 30. Display device 32 may be a fixed-mounted device, such as a desktop PC, an
`
`advanced video game device, such as a Sony "PlayStation 2" device, or a set-top
`
`television controller box, such as the type used to access services such as WebTV© (and
`
`which may also provide game-type functionality), or display device 32 may be a portable
`
`device, such as a laptop PC or a personal digital assistant (PDA). Moreover, WlPS 30
`
`preferably allows different kinds of display device 32 to access the data stored on it at
`
`different times. For example, a user may use a first desktop PC as display device 32 to
`
`20
`
`access the data stored in WIPS 30 at work, may use a PDA as display device 32 to access
`
`the data stored in WIPS 30 while traveling, and may use a Sony "PlayStation 2" device as
`
`display device 32 while at home.

`

`
`Data transfer between WIPS 30 and wireless telephone 24 and display device 32
`
`may occur in various ways. For example, WIPS 30 may be electrically connected to
`
`wireless telephone 24 and/or display device 32. Such electrical connection may be direct,
`
`i.e., so that electrical contacts on WIPS 30 directly contact electrical contacts on wireless
`
`5 telephone 24 and/or display device 32. Alternatively, the electrical connection may be
`
`through electrical cables, which may be provided with standard connectors, such as USB
`
`connectors. Data transfer between WIPS 30 and wireless telephone 24 and display
`
`device 32 may also be wireless. For example, WIPS 30 and either wireless telephone 24
`
`or display device 32 may be provided with infrared ports, such as IrDA ports.
`
`i :::: 71
`
`10
`
`Alternatively, WIPS 30 and either wireless telephone 24 or display device 32 may use
`
`short-range RF communication, such as the Bluetooth protocol, to transfer data. Other
`
`methods for data transfer may also be used. For example, WIPS 30 may be provided
`
`with a flash memory card, in which case data transfer to display device 32 may be
`
`effected by removing the flash memory card from WIPS 30 and connecting it to display
`
`device 32. In any event, the connections between WIPS 30 and wireless telephone 24
`
`and display device 32 may be only intermittent. For example, in some embodiments,
`
`wireless telephone 24 may be directly electrically connected to WIPS 30 most of the
`
`time. However, the user may disconnect wireless telephone 24 from WIPS 30 in order to
`
`make or receive calls.
`
`2O
`
`WIPS 30 receives data transmitted by first wireless network 20 over a
`
`downstream channel 34. Because this data transmission may occur at any time, WIPS 30
`
`is preferably always on in order to receive the transmission. When WIPS 30 receives a
`
`data transmission, WIPS 30 determines whether the transmission is intended for it, and, if
`
`11
`
`Page 15 of 398
`
`

`
`it is, WIPS 30 processes the data transmission accordingly. Typically, this means that
`
`WIPS 30 uses the data from the transmission either to update one or more of the files
`
`stored in its memory or to add a new file to its memory. Preferably, WIPS 30 performs
`
`these functions automatically, so that the user can receive the data while performing other
`
`tasks. As described in more detail below, the user is then able to use display device 32 to
`
`access the data stored in WlPS 30.
`
`Once WIPS 30 has successfully received the data transmission, WIPS 30
`
`preferably sends an acknowledgement signal. In preferred embodiments, WIPS 30 uses
`
`wireless telephone 24 to send the acknowledgement signal to second wireless network 22
`
`...... 10
`
`over an upstream channel 36. To accomplish this, WIPS 30 may make use of electrical
`
`F~-
`
`contacts, provided in most types of wireless telephone 24, that enable wireless telephone
`
`24 to be remotely controlled. Thus, WIPS 30 sends signals to wireless telephone 24 to
`
`cause it to dial a predetermined telephone number and then, once the call is established,
`
`to transmit the acknowledgement signal. Because the acknowledgement signal will
`
`typically be a digital signal, WIPS 30 may use different techniques for transmitting it,
`
`depending on the type of wireless telephone 24.
`
`For example, if wireless telephone 24
`
`can only transmit analog signals, then WIPS
`
`30 preferably modulates the digital
`
`acMlowledgement signal before transmitting it to wireless telephone 24. If wireless
`
`telephone 24 can transmit digital signals, such as signals in CDMA, TDMA, or GSM
`
`2O
`
`format, then WIPS 30 may transmit the acknowledgement signal to wireless telephone 24
`
`in digital packet form.
`
`However, at certain times when WIPS 30 is ready to send the acknowledgement
`
`signal, wireless telephone 24 may not available. For example, wireless telephone 24 may
`
`12
`
`Page 16 of 398
`
`

`
`not be connected to, or in the range of wireless communication with, WIPS 30. Wireless
`
`telephone 24 may also be unavailable because it is turned off or because it is engaged in a
`
`telephone call. When wireless telephone 24 is unavailable, WIPS 30 preferably postpones
`
`the acknowledgement until wireless telephone 24 becomes available for use. First
`
`wireless network 20 will typically re-transmit the data intended for WIPS 30 until the
`
`acknowledgement from WIPS 30 is received.
`
`As an alternative approach, WIPS 30 may be able to transmit wireless signals on
`
`its own, without the need for wireless telephone 24. For example, WIPS 30 may use
`
`cellular digital packet data (CDPD) technology to transmit signals to second wireless
`
`’?il lo
`
`network 22 over upstream channel 26. As another approach, first wireless network 20
`
`may be a two-way network, in which case, WIPS 30 may use the upstream channels of
`
`first wireless network 20.
`
`As noted above, the data stored in WIPS 30 may be accessed by display device
`
`32. Preferably, display device 32 accesses the memory in WIPS 30 as it would an
`
`"~ 15
`
`i,:: =
`
`!’~ !:
`
`external device, such as an external hard drive or a server on a local area network (LAN).
`
`In this way, display device 32 can take advantage of the much larger memory that may be
`
`available in WIPS 30.
`
`In addition, a user may use different display devices to access the data stored in
`
`WIPS 30 at different times. For example, a user may use a desktop PC to access WIPS
`
`20
`
`30 while at home, a laptop PC to access WIPS 30 while at work, a customer’s device to
`
`access WIPS 30 while visiting a customer, and a PDA to access WIPS 30 while traveling.
`
`In this way, WIPS 30 may serve as a convenient storage device so that a user’s important
`
`13
`
`Page 17 of 398
`
`

`
`files are available wherever the user goes and are automatically and continually updated
`
`with new information wherever the user travels within the range of wireless network 20.
`
`In this way, the electronic files stored in WIPS 30 may be automatically updated
`
`to reflect changes in the corresponding electronic files of enterprise IT system 12. This
`
`capability can be very important to a user who maintains important data files on
`
`enterprise IT system 12 at work but who also needs to access the information while the
`
`user is traveling. Such important data files may include the user’s calendar of
`
`appointments, inventory availability and current pricing, contacts, and incoming e-mail
`
`messages.

`
`=: 10
`
`For example, if the user is out of the office, the user’s secretary may use computer
`
`14 to enter a new appointment into the user’s calendar. The calendar is typically stored
`
`as an electronic file on computer 14, enterprise database 16, or elsewhere on enterprise IT
`
`system 12. By means of WIPS 30, the user is able to have access to the updated calendar
`
`in the following way. Enterprise IT 12 sends the information needed to update the
`
`calendar to wireless network management system 29, which, in turn, transmits it to first
`
`wireless network 20 via intermediate network 28. First wireless network 20 then
`
`transmits the update information to WIPS 30 over downstream channel 34. WIPS 30
`
`receives the transmission and uses the information to update the calendar stored as an
`
`electronic file in its memory. To signal that it has successfully received the update
`
`20
`
`information, WIPS 30 uses wireless telephone 24 to transmit an acknowledgement over
`
`upstream channel 26 to second wireless network 22. Second wireless network 22, in
`
`turn, transmits the acknowledgement to wireless network management system 29, via
`
`intermediate network 28. Preferably, wireless network management system 29 resends
`
`14
`
`Page 18 of 398
`
`

`
`the update information, via intermediate network 28, to first wireless network 20 for re-
`
`transmission until management system 29 receives the acknowledgement, in or
