`METHOD AND APPARATUSIN A WIRELESS
`COMMUNICATION SYSTEM FOR
`CONTROLLING A DISPLAY OF TEMPLATE
`DATA BY A PROTABLE SUBSCRIBER UNIT
`
`FIELD OF THE INVENTION
`
`This invention relates in general to wireless communica-
`tion systems, and more specifically to a method and appa-
`ratus in a wireless communication system for controlling a
`display of template data by a portable subscriber unit.
`BACKGROUND OF THE INVENTION
`
`Information services are becoming increasingly popular
`in the wireless service market as they can provide subscrib-
`ers with up-to-date information on stocks, sports, news, and
`the like. To increase the value of these servicesit is helpful
`to customize them for each individual subscriber. Customi-
`zation is not desirable, however,if it requires a large increase
`in the amountoftraffic traveling over the air.
`In prior art wireless communication systems, information
`services providers have broadcast data to an information
`service address which the subscriber unit uses to identify
`information. If the subscriber unit has the address activated
`
`in its registry, it reads and processes the data. The display of
`the data, however, has not been configurable by the end-user.
`In a similar vein, prior art wireless communication sys-
`tems have begun to support access to the Internet. Wireline
`techniques and protocols for Internet access have beentried
`in wireless systems, but have encountered problems. The
`technique of requesting a single WEB page(orportion of a
`page) and then displaying the page (or portion) before
`requesting another page (or another portion of the same
`page), as currently used in the wireline protocols, can
`introduce excessive latency in store-and-forward wireless
`systems. This is because such systems must queue each
`response until adequate air time becomesavailable to trans-
`mit the response.
`Oneprior art technique, known as the Wireless Applica-
`tion Protocol (WAP), has partially addressed the latency
`problem by sending multiple WEB pages, for example, in a
`single transmission as a “deck” of “cards,” each card cor-
`responding to a page of structured content and navigation
`specifications. Each WAP card, however, has combined the
`data to be displayed, with formatting instructions used in
`controlling the display of the data,
`thereby disadvanta-
`geously causing data downloadsto be larger than necessary
`wheneverthe data uses a fixed display format.
`Thus, what is needed is a method and apparatus in a
`wireless communication system for controlling a display of
`data by a portable subscriber unit. In particular, what is
`neededis a method and apparatus that can reducethe size of
`data downloads andthat can allow customization the display
`of the data according to the desires of the enduser.
`SUMMARYOF THE INVENTION
`
`An aspect of the present invention is a method in a
`wireless communication system for controlling a display of
`template data by a portable subscriber unit. The method
`comprises the steps of programminga packinto the portable
`subscriber unit, the pack comprising a bundle of templates
`for formatting the template data for display on at least one
`page; and transmitting the template data from a server in the
`wireless communication system. The method further com-
`prises the steps of receiving the template data by the portable
`subscriber unit, and displaying the template data in accor-
`dance with the pack.

`and a processing system coupled to the receiver for process-
`ing the template data, the processing system comprising a
`memory. The portable subscriber unit further comprises a
`user interface coupled to the processing system for display-
`ing the template data and for accepting an input from a user.
`The processing system is programmed with a pack compris-
`ing a bundle of templates for formatting the template data for
`display on at least one page. The processing system is further
`programmedto cooperate with the user interface to display
`the template data in accordance with the pack.
`Another aspect of the present invention is a server in a
`wireless communication system for controlling a display of
`template data by a portable subscriber unit. The server

`DETAILED DESCRIPTION OF THE DRAWINGS
`
`Referring to FIG. 1, an electrical block diagram depicts an
`exemplary wireless communication system in accordance
`with the present
`invention, comprising an infrastructure
`portion 102 including a controller 112 and a plurality of
`conventional base stations 116, the communication system
`also including a plurality of portable subscriber units 122.
`The base stations 116 preferably communicate with the
`portable subscriber units 122 utilizing conventional radio
`frequency (RF) techniques, and are coupled by conventional
`6
`
`IPR2024-00145

`
`3
`communication links 114 to the controller 112, which con-
`trols the base stations 116.
`
`The controller 112 is preferably a combination of the
`Wireless Messaging Gateway (WMG™) Administrator!
`paging terminal, and the RF-Conductor!™ message dis-
`tributor manufactured by Motorola, Inc. The base stations
`116 are preferably a combination of the RF-Orchestra!
`transmitter and RF-Audience!™ receiver manufactured by
`Motorola, Inc. The portable subscriber units 122 are pref-
`erably similar to PageWriter™ 2000 data messaging units,
`also manufactured by Motorola, Inc., and having software
`modified in accordance with the present invention. It will be
`appreciated that other similar equipment can be utilized as
`well for the controller 112, the base stations 116, and the
`portable subscriber units 122.
`Eachof the base stations 116 transmits RF signals to the
`portable subscriber units 122 via an antenna 118. The base
`stations 116 preferably each receive RF signals from the
`plurality of portable subscriber units 122 via the antenna
`118. The RF signals transmitted by the base stations 116 to
`the portable subscriber units 122 (outbound messages) com-
`prise selective call addresses identifying the portable sub-
`scriber units 122, and data messages originated by message
`originators, as well as commandsoriginated by the control-
`ler 112 for adjusting operating parameters of the radio
`communication system, and packsfor formatting the display
`of template data in accordance with the present invention,as
`described further below. The RF signals transmitted by the
`portable subscriber units 122 to the base stations 116
`(inbound messages) comprise responses that include sched-
`uled messages, such as positive acknowledgments (ACKs)
`and negative acknowledgments (NAKs), and unscheduled
`messages, such as registration requests and pack requests.
`The controller 112 preferably is coupled by telephone
`links 101 to a public switched telephone network (PSTN)
`110 for receiving selective call message originations there-
`from. Selective call originations comprising data messages
`from the PSTN 110 can be generated, for example, from a
`conventional telephone 111 or a conventional computer 117
`coupled to the PSTN 110. In addition, the controller 112
`preferably is coupled through a conventional communica-
`tion link 121 to the Internet 120 for acquiring information,
`e.g., packs and template data, from at least one server 124
`also coupled to the Internet. It will be appreciated that,
`alternatively, the server 124 can be included as an integral
`portion of the controller 112.
`The over-the-air protocol utilized for outbound and
`inbound messages is preferably selected from Motorola’s
`well-known FLEX™family of digital selective call signal-
`ing protocols. These protocols utilize well-known error
`detection and error correction techniques and are therefore
`tolerantto bit errors occurring during transmission, provided
`that the bit errors are not too numerous.It will be appreciated
`that other suitable protocols can be used as well.
`FIG. 2 is an electrical block diagram of an exemplary
`portable subscriber unit 122 in accordance with the present
`invention. The portable subscriber unit 122 comprises an
`antenna 204 for intercepting an outbound message and for
`transmitting an inbound message. The antenna 204 is
`coupled to a conventional transceiver 208 for receiving the
`outbound message and for transmitting the inbound mes-
`sage. The transceiver 208 is coupled to a processing system
`206 for processing the outbound and inbound messages and
`for controlling the portable subscriber unit 122 in accor-
`dance with the present
`invention. A user interface 214
`preferably is also coupled to the processing system 206 for

`conventional display 216 for displaying the inbound and
`outbound messages, a conventional alert element 218 for
`alerting the user when the outbound messagearrives, and a
`conventional keyboard 220 for generating the inbound mes-
`sage and for controlling the portable subscriber unit 122. A
`conventional clock 207 is also coupled to the processing
`system 206 for supporting time keeping requirements of the
`portable subscriber unit 122. In addition, a conventional
`read-only memory (ROM) 205is coupled to the processing
`system 206. The ROM 205 comprises a pack 209 for
`formatting template data for display on at least one page, as
`described further below.
`
`The processing system 206 comprises a conventional
`processor 210 and a conventional memory 212, preferably a
`random access memory (RAM). The memory 212 comprises
`software elements and other variables for programming the
`processing system 206 in accordance with the present inven-
`tion. The memory 212 preferably includes a selective call
`address 222 to which the portable subscriber unit 122 is
`responsive. In addition, the memory 212 includes a message
`processing element 224 for programming the processing
`system 206 to process messages through well-knowntech-
`niques. The memory 212 further comprises a pack cache 226
`for storing a pack utilized by the portable subscriber unit 122
`in accordance with the present invention, as is described
`further below. The memory 212 also includes a pack cus-
`tomization element 228 for programming the processing
`system 206 to customize the pack. In addition, the memory
`212 includes a server access element 230 for programming
`the processing system 206 to allow a user to access the
`server 124 for creating, modifying, and downloading a pack.
`FIG. 3 is an electrical block diagram depicting an exem-
`plary server 124 in accordance with the present invention.
`The server 124 comprises a conventional communication
`interface 304 for communicating with the portable sub-
`scriber unit 122 through the Internet and through the infra-
`structure portion 102 of the wireless communication system.
`The communication interface 304 is coupled to a processing
`system 310 for controlling and communicating with the
`communication interface 304. The processing system 310 is
`also coupled to a conventional clock 336 for providing a
`timing signal to the processing system 310. The processing
`system 310 comprises a conventional computer 312 and a
`memory, preferably a conventional mass medium 314,e.g.,
`a magnetic disk drive, programmed with information and
`operating software in accordance with the present invention.
`The mass medium 314 comprises a conventional message
`processing element 320 for processing messages communi-
`cated with the portable subscriber unit 122 through well-
`known techniques. The mass medium 314 also includes
`generic packs 322 that can be downloaded to the portable
`subscriber unit 122 for controlling the display of template
`data. In addition, the mass medium 314 includes custom
`packs 324 that have been customized by a user of the
`portable subscriber unit 122. The mass medium 314 further
`comprises template data 328 whichis to be transmitted to the
`portable subscriber unit 122 and formatted for display in
`accordance with a pack programmed into the portable sub-
`scriber unit 122. In addition, the mass medium 314 com-
`prises a download element 330 for programming the pro-
`cessing system 310 to download a pack to the portable
`subscriber unit 122. The mass medium 314 also includes a
`create/modify element for programming the processing sys-
`tem 310 to allow a user to create and modify a pack. The
`mass medium 314 further comprises a refresh element 334
`for programming the processing system 310 to periodically
`refresh the pack in a portable subscriber unit 122.

`FIG. 4 is a flow diagram 400 depicting an operation of the
`wireless communication system in accordance with the
`present invention. The flow begins when a pack is pro-
`grammed 402 into the portable subscriber unit 122. The pack
`preferably comprises a bundle of templates for formatting
`template data for display on at least one page. A template is
`a pattern utilized by the processing system 206 and the user
`interface 214 to lay out the presentation of informationto the
`user. The template is created by using a template mark-up
`language, similar
`to the Hypertext Mark-up Language
`(HTML) used in creating World Wide Web pages. A tem-
`plate can, for example, define where, and in what size and
`color, the corresponding template data is to be displayed.
`The templates of the pack can berelated or unrelated in form
`and functionality, depending uponthe use for which the deck
`and template data are intended. A “page,” as used herein,
`refers to a screen of displayed information. The distinction
`between “pack” and “template data,” as used herein, is that
`the pack represents a bundle of templates for displaying
`template data, and the template data is used by the process-
`ing system 206 and the user interface 214 to fill
`in the
`templates. It will be appreciated that the pack can consist of
`a single template, e.g., when the amount of template data is
`small. It will be further appreciated that a user can have a
`plurality of packs stored in a plurality of locations, e.g., in
`the server 124, in a personal computer (not shown), in the
`controller 112, or in the portable subscriber unit 122 (either
`in the ROM 205 or in the pack cache 226).
`After an appropriate pack has been programmedinto the
`portable subscriber unit 122, the server 124 transmits 404
`the template data through the wireless communication sys-
`tem to the intended portable subscriber unit 122. The por-
`table subscriber unit 122 receives 406 the template data and
`then displays 408 the template data in accordance with the
`templates of the pack. Because the pack is separated from
`the template data,
`the pack can be kept
`in the portable
`subscriber unit 122 for future reuse. Keeping the pack in the
`portable subscriber unit 122 advantageously reduces latency
`for template data that is repeatedly updated and displayed in
`a fixed format, e.g., information services data such as a stock
`report. When the pack is stored in the portable subscriber
`unit 122, the pack is preferably cached in the pack cache
`226. It will be appreciated that, alternatively, a frequently
`used pack such as the pack 209, can be programmedinto the
`ROM 205 during manufacture or upon activation of the
`portable subscriber unit 122, for long-time use.
`FIG. 5 is a flow diagram 500 depicting a first program-
`ming operation of the wireless communication system in
`accordance with the present invention. The diagram 500
`begins with the server 124 sending 502 a generic pack to the
`portable subscriber unit 122. Preferably, the generic pack is
`transmitted through the wireless communication system as a
`single unit. The user of the portable subscriber unit 122 then
`can modify 504 the generic pack through the user interface
`214 of the portable subscriber unit 122, thereby producing a
`custom pack. The user then returns 506 the custom pack to
`the server 124 for storing the custom pack. Preferably, the
`transactions between the user and the server 124 take place
`through the wireless communication system.
`It will be
`appreciated that, alternatively, the transactions between the
`user and the server 124 can take place through a wireline
`network as well, when the portable subscriber unit 122 is
`equipped with a conventional wireline network interface
`(not shown). The server then downloads 508 the custom
`pack to the portable subscriber unit 122, preferably as a
`single unit transmission, wheneverthe server 124 sends the
`corresponding template data to the portable subscriber unit

`122. This form of operation advantageously saves memory
`in the portable subscriber unit 122, but at the cost of some
`added latency and air link resources. It will be appreciated
`that, alternatively,
`the custom pack can be stored in the
`portable subscriber unit 122 for improved latency, when
`sufficient memoryis available in the portable subscriber unit
`122.
`
`FIG. 6 is a flow diagram 600 depicting a second pro-
`gramming operation of the wireless communication system
`in accordance with the present invention. The diagram 600
`begins when the user accesses 602 the server 124 from an
`input/output device. The input/output device can be, for
`example, a personal computer, a keyboard-display terminal,
`a display with a handwriting recognition device, a speech
`recognition device, or the portable subscriber unit 122, to
`name a few. The user then creates 604 a new pack, or
`alternatively, modifies a generic pack through the input/
`output device, thereby creating a custom pack. The server
`124 then stores 606 the custom pack on behalf of the
`portable subscriber unit 122. The server then preferably
`downloads 608 the custom pack to the portable subscriber
`unit 122 wheneverthe server sends the corresponding tem-
`plate data to the portable subscriber unit 122. Preferably, the
`pack is downloaded through the wireless communication
`system as a single unit.
`It will be appreciated that,
`alternatively, the server 124 can download the custom pack
`to the portable subscriber unit 122 immediately after the user
`creates the custom pack,and the portable subscriber unit 122
`can store the custom pack in the memory 212, when suffi-
`cient space is available therein.
`FIG. 7 is a flow diagram 700 depicting a third program-
`ming operation of the wireless communication system in
`accordance with the present invention. The diagram 700
`begins with the server checking 702 whether it is time to
`send a refresher pack to the subscriber unit 122. If not, the
`server keeps checking. Whenit is time to send the refresher
`pack, the server 124 sends 704 the refresher pack to the
`portable subscriber unit 122 through the wireless commu-
`nication system. In response, the portable subscriber unit
`122 refreshes 706 the previously saved pack in the memory
`212. This technique is advantageous for updating a pack that
`changes frequently, and for replacing a pack that may have
`been lost when the portable subscriber unit 122 was powered
`down.
`
`FIG. 8 is a flow diagram 800 depicting a fourth program-
`ming operation of the wireless communication system in
`accordance with the present invention. The diagram 800
`begins with the user accessing 802 the server 124 to choose
`a pack. The user then selects 804 a pack from a plurality of
`packsstored in the mass medium 314 of the server 124. The
`server 124 then downloads 806 the pack to the portable
`subscriber unit 122. It will be appreciated that, alternatively,
`the server 124 can store the pack on behalf of the portable
`subscriber unit 122, and download the pack to the portable
`subscriber unit 122 each time the server 124 sends template
`data corresponding to the pack to the portable subscriber
`unit 122. When this alternative is employed,
`the pack
`preferably is downloaded through the wireless communica-
`tion system as a single unit.
`Thus, it should be clear from the preceding disclosure that
`the present invention provides a method and apparatus in a
`wireless communication system for controlling a display of
`template data by a portable subscriber unit. In particular, the
`method and apparatus advantageously reduces the size of
`data downloadsby separating the template from the template
`data, and allows customization the display of the template
`data according to the desires of the end-user.
