`CONTENT PRESENTATION ADAPTATION
`
`FIELD OF THE INVENTION
`
`[0001] The present invention relates to content presenta
`tion adaptation.
`
`BACKGROUND OF THE INVENTION
`
`[0002] WAP (Wireless Application Protocol) is a Widely
`used protocol for delivering Internet content to Wireless
`devices. A WAP compliant mobile system employs WAP
`gateways, Which perform protocol conversion betWeen the
`WAP protocol stack used in the mobile netWork and the
`TCP/IP and HTTP stack used in a WWW (World Wide Web)
`system. These devices are also sometimes referred to as
`WAP proxy servers. Also content encoders and decoders
`may be utiliZed in WAP gateways, particularly to convert
`conventional HTML (Hypertext Markup Language) pages
`into WML (Wireless Mark-up Language) suitable for trans
`mission over the radio interface to Wireless terminals.
`
`[0003] In conventional HTML pages, the page layout, for
`instance colours and fonts, has to be determined Within the
`page description, i.e. in each HTML ?le. HoWever, cascad
`ing style sheets (CSS) have been developed to control hoW
`the content is presented on the screen in the broWser.
`Cascading style sheets separate the presentation (for
`instance spacing, colors, and fonts) from the content (for
`instance document structure, text, and images). Changes to
`the presentation can be made in the style sheet and the
`changes are automatically re?ected throughout the Whole
`document. Cascading style sheets make it easy and cost
`ef?cient to display the same content on a Wide variety of
`devices, each With their oWn display formats and capabili
`ties.
`
`[0004] CSS support has been developed for mobile sys
`tems, too. XHTML together With cascading style sheets
`enable application developers to more easily provide content
`to both WAP and Web domains by using similar markup
`languages and developer tools. There are mobile stations
`Which can use CSS ?les and also WAP gateWays that can
`deliver CSS ?les to mobile terminals via the WAP protocol.
`HoWever, a content creator or another party forming the CSS
`sheets for a HTML/WML page is not alWays aWare of the
`properties of the recipients, and thus the delivered CSS
`sheets are not alWays appropriate.
`
`BRIEF DESCRIPTION OF THE INVENTION
`
`[0005] There is noW provided an improved solution for
`de?ning content presentation for a recipient terminal. This
`improvement is achieved by methods, a system, a commu
`nications device, a module, a mobile terminal, a computer
`program, and a computer program product, Which are char
`acteriZed by What is stated in the independent claims. Some
`embodiments of the invention are disclosed in the dependent
`claims.
`
`[0006] According to an aspect of the present invention, a
`presentation description format for a received object or for
`data derived from the object, to be transmitted to a recipient
`terminal, is arranged by an intermediary control point. The
`received object or data derived from the object is associated
`With presentation description information according to a
`presentation description format or With a reference to pre
`
`sentation description information according to a presenta
`tion description format and transmitted to the recipient
`terminal. The recipient terminal may then present the object
`or data derived from the object in accordance With the
`presentation description information. The term object as
`herein used generally refers to any data structure comprising
`information that may be presented in a recipient terminal, for
`instance a ?le comprising HTML data. The term presenta
`tion description information refers to any kind of informa
`tion de?ning at least some aspect of the appearance of the
`object, for instance a style sheet for a HTML or WML page.
`The association of the object With the presentation descrip
`tion information is to be understood broadly: it may mean
`that the presentation description information is actually
`included in the object or that the presentation description
`information is included for transmission in a same protocol
`data structure as the object, for instance.
`
`[0007] An advantage of the method and arrangement of
`the invention is that a more appropriate presentation format
`and thus a style for content displayable in the recipient
`terminal may be de?ned. This de?nition is performed by an
`intermediary entity and thus there is no need to specify
`presentation formats for different recipients or end systems
`in the device originating the content. Further, a particular
`style may thus be arranged for an XML-based ?le doWn
`loaded from and/or formed by a source not supporting style
`sheets, for instance. When applied to mobile systems, it is
`possible to consider the speci?c aspects of mobile systems
`and the interests of the mobile operators more effectively.
`
`[0008] In one embodiment, an operator or service provider
`speci?c style can be arranged to the mobile terminal by
`operator or service provider speci?c presentation description
`information (or references to such information) selected by
`the control point. The control point may be part of the
`netWork operator’s or service provider’s system. According
`to an embodiment, original presentation description infor
`mation or original reference to presentation description
`information is removed from the received object. Thus
`original presentation description ?le may be replaced by
`another one, for instance by one including the mobile service
`provider’s logo and colour scheme.
`
`[0009] In another embodiment, at least one property asso
`ciated With the recipient terminal is checked by the control
`point. The suitable presentation description format is
`selected on the basis of the property of the recipient termi
`nal. This embodiment enables selection of suitable style,
`taking into account the properties, for instance screen prop
`er‘ties of the terminal. For instance, terminal model speci?c
`style sheets may be utiliZed.

`
`DETAILED DESCRIPTION OF THE
`INVENTION
`
`[0014] FIG. 1 illustrates a networked system, in which
`content may be transferred from a server S to a terminal TE
`via a mobile network MNW and an intermediate entity, in
`the example of FIG. 1 via a WAP gateway GW. The mobile
`network MNW may be an already known or a future mobile
`network, such as a GSM network, a GSM/GPRS network, a
`3G network [for instance a network according to the 3GPP
`(Third Generation Partnership Project) system], a wireless
`local area network (WLAN) or a network combining some
`of these network functions. The assumption in the following
`embodiments is that, from the point of view of data down
`loading, the terminal TE may serve as the client device and
`the server S as the server. However, it is to be noted that
`client-server relationships may exist between the terminal
`TE and the gateway GW, and between the GW and the server
`S. A network server or a PC typically acts as a server S. A
`terminal TE is typically a mobile phone, a PC, a laptop
`computer or a PDA device.
`
`[0015] In one scenario, the server S is a HTTP (hypertext
`transfer protocol) server and communication between the
`gateway GW and the server S is arranged by the HTTP and
`TCP/IP (transport control protocol/internet protocol). The
`WAP (Wireless Application Protocol) is utiliZed for trans
`ferring the data from the WAP gateway GW to the terminal
`TE. The WSP layer (Wireless Session Protocol) of the WAP
`protocol suite is then used to provide transport service for
`the downloading service layer in the client device TE and
`server S. In WAP version 2.0, an HTTP (Hypertext Transfer
`Protocol) can also be used. In this case, the system com
`prises at least one WAP gateway and optionally one or more
`WAP proxy servers. The WAP supports many lower-level
`transfer techniques, such as circuit or packet-switched data
`transfer or SMS-based transfer in accordance with the
`properties of the underlying mobile network MNW. It is to
`be noted that, instead of the example in FIG. 1, the WAP
`gateway GW may be part of the mobile network MNW, even
`implemented in a device performing some other tasks in the
`mobile network MNW.
`
`[0016] A data processing device functioning as the inter
`mediary control point, in the present embodiment as the
`WAP gateway GW, comprises memory, I/O means for
`arranging data transmission and a processing unit compris
`ing one or more processors. Computer program codes
`executed in the processing unit may be used for causing the
`data processing device to implement means for controlling
`the adaptation of the content presentation for mobile termi
`nals (TE) and more precisely the selection of the suitable
`presentation description format for the recipient terminal.
`Some embodiments of these functions are illustrated later in
`association with FIGS. 2a, 2b, 3a, and 3b. A chip unit or
`some other kind of module for controlling the data process
`ing device may in one embodiment cause the device to
`perform the inventive functions. The module may form part
`of the device and could be removable, ie it is insertable into
`another unit or device. Computer program codes can be
`received via a network and/or stored in memory means, for
`instance on a disk, a CD-ROM disk or other external
`memory means, from where they can be loaded into the
`memory of the data processing device. Hardware solutions
`or a combination of hardware and software solutions may
`also be used to implement the inventive functions. It is to be
`
`noted that the presentation description formats for the recipi
`ent terminal may be stored in an internal memory or an
`external memory of the data processing device.
`
`[0017] FIG. 2a illustrates a method according to an
`embodiment of the invention the steps of FIG. 211 may be
`implemented in an intermediary control point, in the present
`embodiment in the WAP gateway GW. The procedure of
`FIG. 211 may be implemented in connection with the pro
`tocol conversion for a received ?le in the WAP gateway GW,
`for instance. It is to be noted that the gateway GW, in which
`the present functionality is applicable, may instead of a WAP
`gateway be a proxy gateway, a mobility gateway, a browsing
`gateway or another intermediate gateway not performing
`protocol conversion to WAP protocols and used for trans
`mitting Internet content to the mobile network MNW. Alter
`natively, the present functionality may be applied in a
`mobile network (MNW) operator control point not compris
`ing any gateway functionality, for instance by additional
`functionality in a node connecting the packet service system
`of the mobile network MNW to the Internet. Such node in
`the GSM/GPRS system and 3GPP system could be the
`GGSN (gateway GPRS support node) or a PEP (Policy
`Enforcement Point). In an alternative embodiment the
`present functionality may be applied in a control point
`outside the mobile network MNW. For instance, such inter
`mediary control point could reside in the Internet, even
`within the server S.
`
`[0018] In step 201 there is a need to transfer a ?le
`including some displayable content to the mobile terminal
`TE. In one scenario, a ?le is received from a HTTP server
`S and the content of the ?le needs to be transmitted to the
`terminal TE. Therefore, the WAP gateway GW may also
`perform encoding functions before or after step 201 (but
`before step 204) to adapt the content from the original
`HTML format to the WML or XHTML format better suit
`able for transmission over the radio interface. In another
`embodiment, the intermediate entity does not change the ?le
`format as such but arranges the transmission of the (HTML,
`XHTML or WML) ?le using the WAP protocol layers used
`between the GW and the terminal TE.
`
`[0019] In step 202 an appropriate style sheet is selected for
`the mobile terminal TE. There are multiple embodiments for
`this step, which are illustrated in more detail later. The GW
`may be arranged to select a pre-determined style sheet or the
`GW may be provided with pre-determined rules on the basis
`of which the style sheet will be selected. Additional infor
`mation from the ?le and/or other network elements may be
`required for this selection step.
`
`[0020] The selected style sheet or reference to the selected
`style sheet is included 203 in the ?le, or in another embodi
`ment in a data structure carrying the ?le. Thus, it might not
`always be necessary to transfer the style sheet to the mobile
`terminal TE if the style sheet already exists in the terminal
`TE or if it is desired that the terminal TE will retrieve the
`referred style sheet from a storage position. Step 203 may
`involve addition of the style sheet or reference to the style
`sheet, and/or at least partial replacement of an existing,
`original style sheet, with the new selected style sheet. For
`instance, if included in the ?le comprising the displayable
`content, the style sheet information may be de?ned by
`adding one or more <style> tags, or directly adding this
`information in a relevant element of the ?le. Further, if an
`

`
`005
`
`

`
`US 2006/0069790 A1

`
`original style sheet or part thereof needs to be removed in
`step 203 or already earlier, the GW may be arranged to
`search for a particular type of ?le (for instance a .css ?le)
`from the received data. The GW may also be arranged to
`parse a received ?le With displayable content in order to ?nd
`a particular tag, and/or more detailed style sheet informa
`tion. If this kind of ?le or an information element Within a
`?le With a displayable content is found, such a ?le or
`information element is removed before step 204. Thus, the
`GW may be provided With one or more removal criteria
`determining the parts of received data to be removed. The
`?le may be transmitted 204 to the mobile terminal. It is to
`be noted that the ?le may also be internally transmitted for
`the recipient terminal (TE). In the present embodiment, at
`least part of the WAP protocol suite may be used.
`
`[0021] FIG. 2b illustrates functions of an embodiment
`suitable for implementation in a client device, in the present
`embodiment in the mobile terminal TE supporting WAP and
`functioning as the WAP client. In step 210 a ?le With
`displayable content is received from the WAP gateWay GW.
`The style sheet included in the ?le by a control point, such
`as the WAP gateWay GW, is retrieved 211 from the ?le, or
`alternatively, the style sheet referred to in the ?le is retrieved
`from an internal or external storage position. This step is
`typically carried out When the ?le needs to be displayed in
`the device (typically immediately after reception). In step
`212 the content in the ?le is presented in accordance With the
`style sheet.
`
`[0022] FIG. 3a illustrates features of an embodiment
`relating to the selection of the style sheet for the mobile
`terminal TE. The features of FIG. 311 can thus be imple
`mented as part of the method illustrated in FIG. 2a. In step
`301 at least one property associated With the terminal TE is
`checked. There are various properties Which may be used in
`the present embodiment. As examples, the siZe of the display
`or support of colours could be used. In one embodiment, the
`GW is con?gured With instructions determining the one or
`more properties Which should be checked. The properties
`may be checked in step 301 from device information main
`tained by GW, from a netWork element of the mobile
`netWork MNW maintaining a terminal information database,
`or by requesting the property information from the TE.
`
`[0023] A suitable presentation description format, in the
`present embodiment the CSS, is selected 302 on the basis of
`one or more properties of the recipient terminal TE. The GW
`may be provided With instructions, for instance a look-up
`table, de?ning Which style sheet is to be selected for Which
`property attribute. There could also be some default style
`sheet, Which is selected if no speci?c style sheet is associ
`ated With the property obtained in step 301.
`
`[0024] There could be further rules taking also the nature
`of the content to be transferred to the mobile terminal. TE
`into account. Thus the above steps could also include the
`checking of one or more properties of the ?le to be trans
`mitted to the mobile terminal TE, and selection of the style
`sheet taking also the properties of the ?le into account. This
`embodiment could also be used independently of the above
`terminal speci?c style sheet selection. Thus the style sheet
`may be selected in step 202 on the basis of one or more
`properties of the ?le to be transmitted.
`
`[0025] According to an embodiment illustrated in FIG.
`3b, subscriber information associated With the recipient
`terminal TE is checked 310 When there is a need to select the
`style sheet for the ?le to the terminal TE (step 202 in FIG.
`2a). This subscriber or user information may be checked by
`de?ning a recipient identi?er on the basis of the message to
`be transmitted to the terminal TE. The style sheet is then
`selected 311 using the subscriber information. A connection
`may be established to a home location register (HLR) of the
`mobile netWork MNW for determining the correct style
`sheet and/or for retrieving subscriber information. Sub
`scriber or subscriber group speci?c style sheets may thus be
`selected. By this embodiment, it is possible to differentiate
`appearance of the Internet content or WAP pages betWeen
`different subscribers or users. For instance, private mobile
`service users may be provided With different style sheets
`than corporate users. In a further embodiment, the subscriber
`information in the home location register may specify
`Whether it is alloWed to change the style sheet and the style
`sheet may be included in the ?le only if this is alloWed in the
`subscriber information.
`
`[0026] In an embodiment, operator speci?c presentation
`description information or references to such operator or
`service provider speci?c information are stored in the inter
`mediary control point. The WAP gateWays GW are typically
`operator speci?c and thus the operator can easily adapt the
`presentation format to have the same look regardless of the
`broWsed content and the location from Which the content is
`retrieved. For instance, a certain operator logo could be
`de?ned in the style sheet in a background frame and an
`operator speci?c colour could be determined as the back
`ground colour. Service provider is in many netWorks an
`entity separate from the actual netWork operator, and the
`latter may be a transparent entity from the user’s point of
`vieW. Therefore, the WAP gateWay GW may be con?gured
`to apply the style sheet of the service provider providing the
`WAP broWsing service or another service for the mobile
`terminal TE.
`
`[0027] The operators and the service providers can then
`effectively use the style sheets for advertising and brand
`maintenance. The application of the style sheet replacement
`is not limited to style sheets of the mobile services providers
`but basically any style sheet could be arranged by the WAP
`gateWay GW or another intermediate entity attending to
`transmission of content to a mobile terminal TE. These
`control points functioning as intermediate entities may then
`be provided With control of the appearance of information in
`the mobile terminal.
`
`[0028] In the folloWing, an example scenario is illustrated.
`An end user is sur?ng the Internet With his mobile terminal.
`A GET request for a particular Web resource (including a
`URL of the resource) is passed via the GW to the Web server,
`for instance the server S. The server S responds With the
`requested content and a CSS associated With the content.
`The WAP gateWay GW is con?gured to remove the original
`CSS and add a selected CSS of a promotional company.
`When this content Will be presented on the mobile terminal’ s
`TE display, promotional information on the CSS is also
`displayed.
`
`[0029] In one embodiment, the style sheets are associated
`With different priority classes. The control point, for instance
`the GW, may be arranged to select a style sheet having the
`
`WHATSAPP INC.'S EXHIBIT NO. 1006
`
`006
`
`

`
`US 2006/0069790 A1
`
`Mar. 30, 2006
`
`highest priority. These priority classes may be adapted
`according to recipient terminal properties, content properties
`and/or some other criteria. Thus the prioritization can be
`applied in at least some of the above-illustrated embodi
`ments. This embodiment gives more ?exibility on the selec
`tion amongst the available style sheets and is especially
`useful When there are multiple style sheets that could be used
`in the receiving terminal. These prioritiZations may change
`over time, for instance.
`
`[0030] In one embodiment, the WAP CSS is utiliZed. For
`more details on the speci?ed WAP CSS, reference is made
`to WAP Forum (currently under OMA (Open Mobile Alli
`ance) WAP speci?cation “WAP CSS Specification, Version
`26-Oct-2001”, 64 pages. Instead of CSS, other presentation
`description information formats may be applied. As an
`example, XSL (XML style sheet) based formats may be
`applied in the control point.
`
`[0031] In an embodiment, instead of the above illustrated
`gateWay GW, the intermediary control point is implemented
`in the recipient terminal (TE) and/or in a module for the
`recipient terminal TE. This module could be a subscriber
`identity module (SIM) in accordance With the GSM standard
`or the 3GPP standard. The module may be removable and
`comprise also other netWork operator or service provider
`speci?c data. The module typically comprises I/O means for
`data transfer With the recipient terminal TE, memory, and a
`processor controlled by a program code store in the memory.
`When a ?le such as a HTML ?le is received, the ?le is
`transmitted to the module. For instance, ?les for a Web or a
`WAP broWser in the terminal TE could be de?ned in the
`recipient terminal TE as ?les to be submitted to the module
`for presentation adaptation. The processor of the module
`may perform the tasks illustrated above in connection With
`FIG. 2a. For instance, the module may at least partially
`remove original style sheet and add a neW style sheet
`predetermined (and/or stored) in the module. The module
`may then send the modi?ed ?le to an entity further process
`ing the ?le. This entity could be an application process in the
`processor unit of the recipient terminal TE. Further, at least
`part of the above illustrated other embodiments could also
`be applied by the module.
`
`[0032] The advantage especially for operator oWned sub
`scriber identity modules is that operator speci?c appearance
`could be arranged for ?les With displayable content even if
`the ?le Was not transmitted via the operator’s netWork or
`gateWay (GW). For instance, if the user is roaming, the
`home operator’s logo could be displayed on a broWsed page
`although the page Was loaded via a roamed netWork of
`another operator. In an alternative embodiment the module
`folloWs the ?les received in the recipient terminal TE. For
`instance, the module may check the ?les for the Web or the
`WAP broWser and performs the presentation adaptation for
`the ?les before presentation by the broWser. The adaptation
`may even be performed by a processor of the recipient
`terminal TE on the basis of a request and a style sheet from
`the module.
`
`[0033] It should be appreciated that the above-illustrated
`embodiments may be combined in various Ways. It Will be
`obvious to a person skilled in the art that, as the technology
`advances, the inventive concept can be implemented in
`various Ways. The invention and its embodiments are not
`limited to the examples described above but may vary Within
`
`the scope of the claims. Di?ferent features may thus be
`omitted, modi?ed or replaced by equivalents.
