Wherein, the HTTP Server Service module of user terminal in gateway device sent request, and request is browsed and is arranged in the Web/WAP application server that the Internet or mobile Internet provide content and service.When thinking that there is personal sensitive information in interaction content, user or website can use the HTTPS agreement that the transmission content is encapsulated.

602:HTTP Server Service module is obtained terminal identification information after receiving user's request.

Wherein, HTTP Server Service module is discerned end message, and therefrom obtains the terminal type information (User-Agent header field) that is used to change, the related contents such as area covered by agreement information (Accept header field), user profile and the network information that the user selects.These information are as the main foundation of follow-up Policy Service module application switching strategy.

603:HTTP Server Service module is transmitted to the PolicyService module by api function or soap protocol with user's request, and carries the corresponding terminal identifying information.

Wherein, select api function or soap protocol according to the requirement in the specific implementation process, the api function purpose is to improve performance, and soap protocol then can carry out distributed deployment and open interface.

After 604:Policy Service module is received request from HTTP Server Service module, carry out distribution policy and handle.

Wherein, door is showed if solicited message is request, promptly asks the portal website of this gateway equipment, then directly returns the corresponding information of the portal website of this gateway equipment to terminal, otherwise carries out 605.

605: after Policy Service module confirms that request is for the portal website of non-gateway equipment, Policy Service module will ask to be forwarded to HTTP Client Service module accordingly.

Comprising, forward the request to HTTP Client Service module, and preserve this request relevant terminal identifying information.

The above-mentioned Web/WAP website of asking of 606:HTTP Client Service module forwards to appointment.

Wherein, the Web/WAP website of appointment is that request URL (Uniform Resource Locator, URL(uniform resource locator)) address is specified.

The 607:Web/WAP server is back to HTTP Client Service module with the HTTP/HTTPS response message corresponding with request.

608:HTTP Client Service module is carried out the response message content recognition to response message.

Wherein, the content aware step of response message comprises: the content of Content-Type in the response header field of analysis HTTP/HTTPS, thereby the protocol suite under the clear and definite message; And System-ID and Public-ID in the message content, therefrom obtain the content encoding (as UTF-8, GB2312 etc.) of message and the agreement of content, so clear and definite message content coding, the information such as concrete agreement that message is used.

The HTTP/HTTPS response message that this Web/WAP server of 609:HTTP Client Service module forwards returns is to Policy Service module, and carries the response message content identification information.

610:Policy Service module is carried out distribution policy to response message and is handled.

Wherein, Policy Service module according to before the response message content identification information returned of the terminal identification information preserved and HTTP Client Service module judge, if terminal supports the agreement of request message content then gateway device carries out 617; Otherwise carry out 611.

The 611:Policy Service module switching strategy that carries on an agreement.

Wherein, Policy Service module is according to corresponding transformation rule in terminal identification information, the response message content recognition search database.This transformation rule is that gateway device sets in advance common default (rule that does not promptly have condition), and supports the conditional plan of particular terminal, particular network, particular server, and supports rule to merge.The influencing factor of Rulemaking comprises the agreement that the maximum capacity, the network bandwidth, server of terminal are supported, coordinates each factor and reaches the preferable experience of user.

612:Policy Service module is transmitted to Transform Service module with response message, and carries transformation rule in this response message according to the transformation rule that inquires.

613:Transform Service module is carried out the protocol format checking of response message content.

Wherein, the protocol format checking to the response message content comprises whether checking message content form is good, whether meets DTD and describes.If format verification by carry out 615; Otherwise carry out the format content reparation according to the format verification error reporting, promptly execution in step 614;

Particularly, the response message content is carried out format verification to be comprised: the Name Space (NameSpace) from message content obtains DTD (Document Type Definition, DTD) document name, according to the document name, take out corresponding D TD Format Type defined file from database, whether the authentication response information format of content meets DTD is described.

614:Transform Service module is carried out the message content reparation.

The target of carrying out the message content reparation is to produce to meet the message content that DTD describes, and message content can't be handled when avoiding format conversion.

615:Transform Service module is carried out the conversion of protocol format content.

Wherein, carrying out format content conversion mainly is to be divided into two stages: the transformation rule that provides according to Policy Service module is at first confirmed the agreement from which protocol conversion to appointment, takes out corresponding grammer mapped file then from database; The content of the content of changing fully according to the needs of stipulating in the transformation rule, not exclusively conversion and the content (this content only keeps corresponding literal) do not changed are fully determined the original and the grammer mapped file of needs filtration again, do not handle if the content of the conversion of not requiring is clearly arranged in the foregoing then abandon or keep, at last produce message content after the final conversion according to the grammer mapped file.

In the above-mentioned original of need filtering, the condition of filtration is diversified, and for example can filter in some webpages can not content displayed or filter the content that can't resolve.Because the condition of filtering is diversified, so transformation rule also is variable.

616:Transform Service module will be forwarded to Policy Service module through the message content of conversion.

617:Policy Service module forwards response message is to HTTP Server Service module.

Wherein, with 610 corresponding, Policy Service module directly transmitted response to HTTP Server Service module or notice HTTP Server Service module is carried out HTTP redirection, the content that this HTTP redirection represents finally will to issue the response message of terminal is a redirect response, terminal is obtained the URL that service finally is provided for the user according to redirect response, asks corresponding resource according to this URL again;

Wherein, Policy Service module judges whether the response message content of terminal identification information and the network information, server mates (comprising information such as the network type and the network bandwidth), if coupling, expression needn't be carried out the conversion of protocol format, and then carries out HTTP redirection.

With 616 corresponding, Policy Service module also can be transmitted message content through Transform Service module converts to HTTP Server Service module.

618: terminal equipment receives the HTTP/HTTPS response message, and finally gives the terminal use by browser-presented.

Above-mentioned user use the gateway device browse service method 611 in, the protocol conversion strategy comprises two key contents: the mutual transformational relation of agreement, the conversion granularity.

Below by the transformational relation between Figure 14 description protocol:

As shown in figure 14, this transformational relation comprises that scope is the mutual conversion between WML protocol suite, HTML protocol suite and the XHTML protocol suite.Wherein the WML protocol suite comprises WML 1.X series (being WML 1.1, WML 1.2 and WML 1.3), agreements such as WML 2.0; The HTML protocol suite comprises agreements such as CHTML (Compact HTML), HTML 2.0, HTML 3.0 and HTML 4.0; XHTML has then comprised agreements such as XHTML 1.0, XHTML 1.1 and XHTML 2.0.

The switch target of transformational relation shown in Figure 14 is between the above three big protocol suites and the mutual conversion between protocol suite inside.Conversion refers to two kinds of conversions between agreement mutually.Have six kinds of conversions between WML, HTML and the XHTML.Wherein the dotted line between WML and the HTML is represented directly not change between WML and the HTML, and the conversion between them is changed as medium by means of XHTML, and promptly WML will convert HTML to, and at first WML changes XHTML earlier, is mapped to HTML then, and vice versa.XHTML is the core and the final goal of this method conversion, to keep promoting with present W3C (WorldWide Web Consortium World Wide Web Consortium) congruence of XHTML development.In addition, if XHTML convert to HTML be the former of dotted line because most of browser supports that HTML also can support XHTML, and XHTML 1.0 be the good HTML of form, do not need to change.The protocol suite internal conversion is an example with certain agreement among Figure 14, the mutual conversion of inner other agreement of realization and protocol suite, thereby the mutual conversion of institute's protocols having in the realization protocol suite.

Because the conditions such as agreement that terminal capability, the network bandwidth, server are supported at present are even carry out the demand that protocol conversion completely also can't be satisfied the terminal use.For example file such as flash, zip bag is subject to the network bandwidth, hardware conditions such as mobile phone EMS memory, computing capability.Therefore some content in the response message content can abandon or ignore operations such as modification.And abandon, ignore, the content of operation such as modification need consider granularity problem.About grain size analysis, can be included as module, two kinds of granularities of element.Module is to adopt the thinking of XHTML Modularization (modularization), the response message content can be divided into module (module), definition according to XHTML can probably be divided into 28 modules to message content, as text, and modules such as form, script, image module.Simultaneously can support the more operation of small grain size, for example element in the message content or attribute be operated.

The embodiment of the invention requires the design agreement transformation rule according to above-mentioned transformational relation, protocol conversion scope and conversion granularity.This transformation rule has defined regular collection, and terminal use or terminal phone model can corresponding one or more regular collections.A regular collection can comprise zero or a plurality of rule.Wherein rule has comprised condition, operation and converted contents three parts, wherein the converted contents module and the element that have comprised the translation-protocol type and abandoned and ignore.

User profile (PhoneNumbers), end message (UserEquiment), the network information (NetWork) and response contents message (MessageContent) have been comprised in the condition.User profile has comprised phone number, and identify labels such as user id can be provided with zero or a plurality of user in the condition.End message comprises terminal models, and the information such as area covered by agreement that terminal is supported can be provided with zero or a plurality of end message equally.The network information has then comprised the network bandwidth (network uplink and downstream rate) and network type (Internet, 2.5G (GSM/GPRS), 3G network (CDMA, WCDMA, TD-SCDMA) etc.).The response message content has comprised the protocol suite and the concrete agreement of use under the message.The input of these conditions source terminal request, server response and server carry out data and expand the information that obtains (for example obtain the more detailed more detailed software and hardware information of this terminal according to terminal models from network, and the phone number sign in user's registration or the user's request).

Operation has comprised two selections, promptly whether allows conversion.Allowing is exactly allow, and not allowing is exactly block.

Converted contents has comprised the input (OriginTransform) and output (TargetTransform) form of converted contents, and needs content (DiscardContent) that abandons and the content of ignoring (IgnoreContent) in transfer process.Wherein abandon content (DiscardContent) and ignore the content that content (IgnoreContent) has comprised element and module.Whether element has comprised contents such as script (script), picture, and has comprised corresponding prefix (prefix) and suffix (suffix) condition judgment, promptly abandon or ignore operation to judge whether operation according to the prefix and the suffix of the content in the message.Module contents has comprised nucleus module (coreModule), text module (TextModule) etc.

Referring to Figure 15, the application process flow chart of the protocol conversion rule that provides for the embodiment of the invention comprises the application to above-mentioned transformation rule set in this method.Because in concrete implementation process, for multiple end message, user's different demands and special website, a transformation rule in the XML transformation rule file is difficult to satisfy the requirement of conversion, in order to reach the optimum efficiency of changing between agreement, need the rational Application transformation rule, promptly select the optimum translation rule, therefore method shown in Figure 15 provides the application to above-mentioned transformation rule set, specifically comprises:

801:Policy Service module is obtained XML transformation rule file from database, and reads a rule under rule (rule) root element.

Wherein, Policy Service module is obtained XML transformation rule file according to terminal request message content and server response message content from database.

802:Policy Service module is obtained the daughter element condition (condition) under the rule element, judge subscriber phone number in the terminal identification information, terminal equipment, the network bandwidth, whether meet the requirement of transformation rule condition with the response message type in the server response message content, be then to carry out 804, otherwise carry out 803.

803: abandon this transformation rule, carry out 807 afterwards.

804: judge whether transformation rule allows to use, and is then to carry out 806, otherwise carries out 805.

805: keep not allow the transformation rule used, carry out 807.

806: keep the transformation rule that allows application, and carry out the merging of transformation rule.

Particularly, allow the transformation rule of conversion directly to keep for the article one that runs in the implementation; And allow the transformation rule of conversion for the non-article one that runs into, the content of its content and transformation rule is before merged, the principle that merges is as the criterion with the optimum efficiency of Target Transformation agreement, for example, Target Transform (being target protocol) gets more senior abundant agreement of content or the higher agreement of version.The content that abandons and ignore is then minimum with the content that abandons to be principle.

807: judge whether also to exist next bar rule, if then carry out 801, otherwise execution in step 808.

808: read rule and finish, carry out 809 afterwards.

809: the operation according to 805 and 806 produces final transformation rule content.

Wherein, if whole flow process does not carry out 806, then be as the criterion and do not carry out any conversion with 805 result; If the condition without any rule matches this conversion, promptly the terminal identification information in 802, the response message content of server all do not meet the requirement of rule condition, then keep relevant information to database and to notify administrator terminal to carry out rule newly-increased or revise; Otherwise be as the criterion with 806 converted contents that produce, determine the initiation protocol (OriginTransform) and Target Transformation agreement (TargetTransform) changed; Simultaneously, in the process of conversion, the content that is finally abandoned according to 806 results that produce; The content of finally being ignored according to 806 results that produce.

The purpose that rule merges is provided in the application process of the protocol conversion rule that provides for Fig. 8 to be: since the diversity of rule condition and the content that needs to transform and uncertainty (may continue later on increases, also be extensibility), cause being difficult to annotating terminal, certain server of a certain type, certain user's conversion with a transformation rule.

Select only transformation rule concrete reason to have:

(1) the rule merging emphasizes to reuse (or being called reconstruct) notion, rather than exclusiveness.Much conditions and converted contents are interrelated and interact, and can not just all increase or give up original content newly because of the modification of certain condition and certain converted contents.For example: meta-rule 2G mobile phone access WAP site uses the wap1.x agreement, but uses wap2.0 when certain user wishes to visit the sina website.If service regeulations merge and can reuse, and original rule do not waste yet, and can superpose, and need not any variation for other user.

(2) target of rule merging is the most full rule application, rather than optimal rules is used.If optimal rules will inevitably cause Else Rule to use so.

Use description in the gateway device browse service method flow according to user shown in Figure 13, after Policy Service module was carried out switching strategy, Transform Service module was carried out 613 in the browse service flow process, carries out the corresponding protocol conversion process.

In order to realize the conversion between WML protocol suite, HTML protocol suite and the XHTML protocol suite, conversion process has comprised the conversion to other agreement by HTML, WML and XHTML.

The embodiment of the invention illustrates transfer process between WML protocol suite, HTML protocol suite and the XHTML protocol suite by Figure 16～Figure 18.

Referring to Figure 16, for the WML protocol suite to other method for converting protocol flow charts, this method is that a certain agreement comprises to the step of other protocol conversion in the Transform Service resume module WML protocol suite:

901:Transform Service module receives WML body (message body) content in the http response message, carries the messaging protocol version in the message body.

902:Transform Service module is obtained corresponding DTD formatted file according to the messaging protocol version among the WML body from database, and according to this dtd file checking WML body, judges whether the content format of WML body is legal.If the checking result is legal, then carry out 904; Otherwise will carry out 903.

Particularly, Transform Service module is according to the messaging protocol version among the WML body, NameSpace from message content (NameSpace) obtains the DTD document name, according to the document name, from database, take out corresponding D TD Format Type defined file, according to this dtd file checking WML body.

903: the checking result according to DTD carries out the reparation of message content form, carries out 904 afterwards.

WML body after the reparation meets the requirement of DTD formatted file.For example, the title element does not have content among the WML, and it is Untitle that content then can be set.

904: according to content through the daughter element DiscardContent in the transformation rule of Policy Service resume module, judge whether transformation rule needs to abandon the appropriate section message content, carry out content if desired and abandon and then carry out 905, otherwise carry out 906.

Wherein, the content of daughter element DiscardContent is based on needs the content (DiscardContent) that abandons in the transformation rule through Policy Service resume module in the application process of the transformation rule set that Figure 15 provides.

905: the content at Discard Content is changed operation, carries out 906 afterwards.

Wherein, the content of Discard Content being changed operation comprises operations such as WML body delete, changes.Can use C++ or java to operate simultaneously for the operation of element or attribute, simultaneously, preferably can use the XSLT technology to operate.For example, need the template element is abandoned in this conversion of WML body, the XSLT grammer can be expressed as:＜xsl:if test=" //template "＜/xsl:if 〉.

906: the content according to through the daughter element IgnoreContent in the transformation rule of Policy Service resume module judges whether to ignore the content in the Transformational Grammar.Ignore some syntax conversion if desired and then carry out 907, otherwise carry out 908.

Wherein, the content of daughter element IgnoreContent is based on needs the content (IgnoreContent) ignored in the transformation rule through Policy Service resume module in the application process of the transformation rule set that Figure 15 provides.

907: according to the filter of the content generative transformational grammar of IgnoreContent.

Wherein, the effect of mapping filter is that XSLT grammer mapped file is filtered operations such as comprising deletion, modification, promptly deletes the grammer mapping part of coherent element or attribute.This operation can use traditional C++ or java to make amendment, but the preferred XSLT technology of using.For example: do not need the option element is carried out the grammer mapping in this conversion of WML body, the grammer that the XSLT grammer is made amendment to the grammer mapped file is:＜xsl:iftest=" //template/@match=' option ' "＜/xsl:if 〉.

908:, judge that whether the switch target agreement is the HTML protocol suite, if then carry out 909, otherwise carries out 910 according to content through the daughter element TargetTransform in the transformation rule of Policy Service resume module.

909: from database, take out the xsl file of WML, and this XSL Transformational Grammar file applications filter is filtered, carry out 912 afterwards to the syntax conversion of XHTML 1.0.

Wherein, judged result WML according to 908 will be transformed into HTML, can at first from database, take out XSL (the eXtensible Stylesheet Language that corresponding WML is mapped to the syntax conversion of HTML protocol suite, XSL) file, because the popular browser in the Internet is generally supported Transitional (transition) pattern among the XHTML 1.0 at present, if therefore WML will be transformed into HTML, then can directly take out the xsl file of WML to the Transitional of XHTML 1.0, and this xsl file is used filter carry out the filtration of syntax conversion file, carry out 912 afterwards.

910: whether the content of judging Target Transform is the XHTML protocol suite, if then carry out 911, otherwise carries out 913.

911: from database, take out the syntax conversion xsl file that corresponding WML is mapped to the XHTML protocol suite, and this XSL Transformational Grammar file applications filter is filtered.

912: change by the XSLT technology according to the grammer difference between WML and the XHTML protocol suite, finish afterwards.

Wherein, the grammer of WML can be represented by grammer and the javascript of XHTML self.By XHTML syntactic representation WML, for example: wml card ontimer attribute representation The ontimer event occurs when a timer expires, can use the daughter element refresh of head/meta element among the xhtml to realize.

Concrete grammer implementation method sees the explanation of the embodiment of the invention to the grammer mapping process for details.

913: judge that whether WML converts other agreement in the WML protocol suite to, is then to carry out 914, otherwise carries out 916.

Wherein, the conversion between the WML protocol suite internal agreement for example converts WML 1.1 to from WML 2.0, perhaps converts WML 1.3 to from WML1.1.

914: from database, take out the syntax conversion xsl file that corresponding WML is mapped to the WML protocol suite, and this XSL Transformational Grammar file applications filter is filtered, carry out 915 afterwards.

915: the grammer difference according to WML and other agreement of WML protocol suite is changed by the XSLT technology.

For example, WML 1.3 exists element head, meta, select, differences such as template with WML 2.0.Wherein, template does not exist in WML 2.0.And daughter element that other element comprises and attribute are had nothing in common with each other, and therefore need carry out the grammer mapping.

916: EOC.

Referring to Figure 17, for the HTML protocol suite to other method for converting protocol flow charts, this method is that a certain agreement comprises to the step of other protocol conversion in the Transform Service resume module HTML protocol suite:

1001:Transform Service module receives HTMLbody (message body) content.

1002: HTML is carried out the content format reparation.

Wherein, HTML is carried out the content format reparation, make this content format directly become Transitional pattern among the XHTML 1.0, can adopt preferred conversion regime (XSLT) to change in the subsequent transition procedure thereby make.It is correctly nested that W3C normal structure XHTML 1.0 standards (http://www.w3.org/TR/xhtml1/) have pointed out that mainly XHTML requires, element and attribute need small letter, element must have end mark, property value is wanted double quotation marks, can not minimize by attribute, handle in the space of property value, and spcial character is handled, and replaces name attribute etc. with the id attribute.For example,＜p〉here is an emphasized＜em〉paragraph.＜/p〉＜/em〉in XHTML, belong to illegal, correct content is:＜p〉here is an emphasized＜em〉paragraph＜/em 〉.＜/p 〉.By the content reparation, the HTML content will become the form of XHTML 1.0.

1003:, judge whether to abandon the partial content in the message according to through the DiscardContent content in the transformation rule of Policy Service resume module.Then carry out 1004 if desired.Otherwise carry out 1005.

1004: the content to DiscardContent abandons operation, carries out 1005 afterwards.

Wherein, to the content of DiscardContent change operation comprise to XHTML body delete, operation such as modification.For example, in this conversion, do not need the content of javascript, can use the XSLT grammer to delete, that is:＜xsl:iftest=" //script "＜/xsl:if 〉.

1005: the content according to through the daughter element IgnoreContent in the transformation rule of Policy Service resume module, judge whether to ignore the content in the Transformational Grammar, be then to carry out 1006, otherwise carry out 1007.

1006: according to the filter of the content generative transformational grammar of IgnoreContent.

For example, do not need to use the style element in this conversion, then can use grammer:＜xsl:iftest=" //style "＜/xsl:if 〉.

1007: according to content, judge whether the object content of this conversion is the WML protocol suite, be to carry out 1008, otherwise carry out 1010 through the TargetTransform in the transformation rule of Policy Service resume module.

1008: from database, take out the xsl file that XHTML is mapped to WML, and this XSL Transformational Grammar file applications filter is filtered.

1009: by XSLT syntax parsing protocol conversion xsl file, the XHTML content is changed, produced corresponding WML message.

For example: the message content of XHTML 1.0 protocol formats converts in the message process of WML 1.3, and the body element of XHTML 1.0 refers to the content of message body, among the WML 1.3 then with card element representation message body.Therefore xsl file is described as:＜xsl:template match=" body "〉＜card〉...＜/card〉＜/xsl:template 〉.

1010: whether the content of judge changeing the Target Transform in the rule is other agreement in the HTML protocol suite, is then to represent and need change in HTML protocol suite inside, promptly carries out 1012, otherwise carries out 1011.

1011: whether the content of the TargetTransform in the judgment rule is the XHTML protocol suite, is then to carry out 1012, otherwise carries out 1014.

1012: from database, obtain the xsl file of HTML, and this XSL Transformational Grammar file applications filter is filtered to the Transitional of XHTML 1.0.

Because browser is all supported XHTML 1.0 at present, the mapping unification that therefore converts HTML protocol suite grammer to converts XHTML 1.0 to, is understandable that, according to the actual needs, can carry out accurately protocol conversion.

1013: use XSLT analysis protocol conversion xsl file, finally produce corresponding XHTML file.

1014: finish conversion.

Referring to Figure 18, for the XHTML protocol suite to other method for converting protocol flow charts, this method is that a certain agreement comprises to the step of other protocol conversion in the Transform Service resume module XHTML protocol suite:

1101:Transform Service module receives XHTML body (message body) content.

1102: obtain corresponding dtd file according to the protocol type of XHTML body statement and verify whether form is good to judge XHTML message, be execution 1104, otherwise carry out 1103.

1103: message content is repaired according to DTD checking report.

Message content is repaired, made the XHTML message content meet DTD protocol definition form.

1104: according to judging through the element DiscardContent content in the transformation rule of Policy Service resume module that in this conversion needs whether abandon part of module and the element in the message, are then to carry out 1105, otherwise carry out 1106.

1105: XHTML message is revised according to the DiscardContent content.

For example, do not need the link element in this conversion.Can use the XSL grammer to delete.Grammer is:＜xsl:templatematch=" link "〉＜/xsl:template 〉.

1106: the conversion according to judging through IgnoreContent content in the transformation rule of Policy Service resume module in this conversion whether needs are ignored some element in the message is then to carry out 1107, otherwise carries out 1108.

1107: according to the filter of the content generative transformational grammar of IgnoreContent.

This Transformational Grammar filter can be an xsl file, for example, needs to ignore picture in this conversion, and corresponding grammer is:＜xsl:template match=" img "〉＜/xsl:template 〉.

1108: according to judging through the content of TargetTransform in the transformation rule of Policy Service resume module whether the target protocol of this conversion is the WML protocol suite, is then to carry out 1109, otherwise carries out 1111.

1109: from database, take out the protocol conversion xsl file of XHTML, and this XSL Transformational Grammar file applications filter is filtered to the mapping of WML protocol suite.

1110: by XSLT engine analysis protocol conversion xsl file, the XHTML content is carried out syntax conversion, produce corresponding WML message.

For example, convert in the message process of WML 1.3 at the message content of XHTML 1.1 protocol formats, the form element of XHTML 1.1 refers to terminal to server and submits content to, then acts on like the same representation class of go element among the WML 1.3.Therefore xsl file is described as:＜xsl:template match=" form "〉＜go〉...＜/go〉＜/xsl:template 〉.

1111: whether the target protocol of judging this conversion according to the content of TargetTransform is the HTML protocol suite, is then to carry out 1113, otherwise carries out 1112.

1112: judge that whether this switch target agreement is the conversion of XHTML protocol suite inside, is then to carry out 1113, otherwise carries out 1115.

Wherein, the conversion of XHTML protocol suite inside for example is converted to XHTML 1.1 or XHTML 2.0 from XHTML 1.0.

1113: from database, obtain the xsl file of HTML, and this XSL Transformational Grammar file applications filter is filtered to the Transitional of XHTML 1.0.

Because browser is all supported XHTML 1.0 at present, the mapping unification that therefore converts HTML protocol suite grammer to converts XHTML 1.0 to, is understandable that, according to actual conditions, can carry out accurately protocol conversion.

1114: use XSLT engine analysis protocol conversion xsl file, produce corresponding XHTML file.

1115: no corresponding protocol conversion coupling in the transformation rule, notify the keeper can't handle EP (end of program).

In the transfer process between three above-mentioned big protocol suites, the grammer mapping is a committed step.And the key that realizes the grammer mapping is by the identical semanteme of different grammatical representations, thereby realizes representing same or analogous content and function.The process of grammer mapping is similar to the principle of programming language, and for example, same function can realize by C++, also can realize by java.And the means that the grammer mapping realizes are to resolve source contents and be modified as object content by program.The embodiment of the invention adopts XSLT to substitute C++ and the java grammer carries out source contents is carried out analytic modification, forms syntax conversion and uses.

In the conversion implementation procedure of WML, HTML and XHTML, repeatedly mention the mapping of protocol conversion xsl file and XSL grammer in the processing procedure.No matter adopt which kind of grammer, in the process of conversion, the logic rules of its conversion are constant, are the avatar difference of different grammers.Becoming the logic rules of another agreement mapping below from grammer specific implementation angle explanation a certain protocol conversion from three big protocol suites, is that target XHTML 1.0 is an example with source contents WML 1.3 protocol conversions:

Describe according to the DTD of WML 1.3 and to know and have 36 elements among the WML 1.3 that each element all has corresponding a plurality of attribute.WML grammer and XHTML grammer compare, and wherein element/property comprises four kinds of situations: the element/property of former grammer is present in the target grammer, and the implication unanimity; Though the element/property of former grammer is present in the target grammer, but implication is variant, meta for example, select, optgroup, input, img, a, br, head, option, fieldset, table, tr, td, em, strong, b, i, u, big, small, p, 23 of pre etc.; Former grammer element/property is not present in the target grammer, expresses but can carry out equivalent logic by the target grammer; Former grammer element/property neither is present in the target grammer, can not carry out equivalent logic by the target grammer again and express.Therefore can adopt diverse ways conversion at this four dvielement:

Referring to Figure 19, Grammatical transformation method flow chart between the agreement that provides for the embodiment of the invention comprises:

At first receive the content of protocol message body; Afterwards, carry out 1201:

1201: from protocol contents, take out an element/property, judge whether the element/property of former grammer exists in the target grammer, be then to carry out 1202, otherwise carry out 1204.

1202: judge that the implication of this element/property in former grammer be whether consistent with implication in the target grammer, is that then program carries out 1203, otherwise carries out 1204.

1203: duplicate this element/property in the target grammer.

Wherein, this element/property that the judged result according to 1201,1202 draws former grammer is present in the target grammer, and the implication unanimity, then duplicates this element/property in the target grammer.

1204: judge that whether this element/property in the former grammer has the grammer of implication of equal value in the target grammer, be then to carry out 1205, otherwise carry out 1206.

1205: in the target grammer, use the grammer of implication of equal value to represent or revise to this element/property in the former grammer.

Wherein, judge that according to 1204 drawing this element/property of former grammer can not copy in the target grammer fully, therefore, need in the target grammer, use the grammer of implication of equal value to represent or revise, comprise two kinds of situations: express or revise attribute this element/property in the former grammer; Express or revise element and attribute.

(1) express or the modification attribute.

For example, WML meta element comprises http-equiv altogether, name, and forua, content, scheme, id, attributes such as class, forua wherein, it is peculiar that class belongs to WML.Can analyze the semanteme of forua and class, according to the description of OMA (OpenMobile Alliance, Open Mobile Alliance) standard, the class attribute is negligible; The forua attribute represents then whether meta will delete.This conversion logic can pass through grammers such as C++, java, XSLT to be realized, wherein, adopts the Transformational Grammar of XSL to realize that above-mentioned logic is:

<xsl:template?match＝″meta″>

<xsl:when?test＝″boolean(@forua)and?@forua＝′false′″/>

<xsl:otherwise>

<meta>

<xsl:copy-of?select＝″@http-equiv|@name|@content|@scheme|@id″/>

<xsl:if?test＝″boolean(starts-with(@content，′text/html′))″/>

</meta>

</xsl:otherwise>

</xsl:template>

(2) express or revise element and attribute.

For example, use the XHTML dynamic web page to realize that WML changes to XHTML, can use XHTML self grammer or plug-in unit grammer (as javascript, ActiveX, flash, wmlscript, java applet etc.) to realize its conversion.Self grammer is for example realized, WML card ontimer attribute representation event when timer expires can be used daughter element refresh realization in the head/meta element among the XHTML.

Again for example, some grammer relates to the forward-reverse of browser among the WML, for example onenterforward and onenterbackward.Onenterforward represents the redirect of advancing, and onenterbackward then is that expression retreats redirect.What this WML described is control browser forward-reverse function, the user from other page jump during to this page browser can advance and jump to http:3g.sina.com.cn.The XSLT grammer of advancement function is embodied as:

<xsl:if?test＝″starts-with(//card/onevent/@type，′onenterforward′)and//card/onevent/go/@href″>

<xsl:attribute?name＝″content″>

<xsl:value-of?select＝″concat(1，′；url＝′，//card/onevent/go/@href)″/>

</xsl:attribute>

</meta>

</xsl:if>

1206: gateway device is expressed the implication of this element/property by program.

Judge according to 1204 and to draw in the former grammer that this element/property can not be carried out the grammatical representation of implication of equal value by the target grammer fully or when revising, can adopt this moment gateway device to express the logic implication of this element/property, promptly carry out the WML grammer alternately and control by terminal and gateway device by program.Wherein, the program that gateway device adopts can be C++, Java etc.

The forward-reverse that relates to browser with some grammer among the above-mentioned WML is the example explanation again.Onenterforward represents the redirect of advancing, and onenterbackward then is that expression retreats redirect.It is as follows to carry out the control of WML grammer by gateway device and terminal interaction:

<wml>

<card>

<onevent?type＝″onenterforward″>

<go?href＝″http://3g.sina.com.cn″/>

</onevent>

<onevent?type＝″onenterbackward″>

<go?href＝″http://wap.baidu.com″/>

</onevent>

</card>

</wml>

What this WML described is control browser forward-reverse function, from http: need forward http://wap.baidu.com to when // 3g.sina.com.cn retreats into this page.Do not control to javascript and the forward-reverse function of IE browser is open, therefore can handle by gateway device, can not carry out buffer memory by the program control IE page, gateway device then writes down this request, promptly carries out buffer memory by gateway device.When if the IE browser retreats, the IE browser can be initiated browse request again, can realize page fallback function.

The embodiment of the invention provides a kind of equipment of realizing the syntax conversion of protocol message body protocol contents, and this equipment comprises:

Second judge module is used for judging whether the implication of the element/property in element/property and the target grammer in the former grammer of the protocol message body protocol contents of receiving is consistent;

The 3rd judge module is used for judging whether element/property in the former grammer of the protocol message body protocol contents of receiving exists the grammer of implication of equal value in the target grammer;

Replication module, be used for when the judged result of second judge module when being, duplicate element/property in the former grammer of protocol contents in the protocol message body of receiving to the target grammer;

Expression/modified module, be used for when the judged result of the 3rd judge module when being, use the element/property in the former grammer of protocol contents in the syntactic representation of implication of equal value in the target grammer or the protocol message body that modification is received;

Representation module, be used for when the judged result of the 3rd judge module for not the time, express the element/property in the former grammer of protocol contents in the protocol message body of receiving by logic control.

The equipment of above-mentioned realization syntax conversion is used to realize the syntax conversion between the different agreement, no matter adopts which kind of language to change, all can adopt the said equipment with and corresponding conversion method carry out the conversion of different agreement.

The gateway device of the embodiment of the invention is supported the method for mutually conversing of WML, HTML and XHTML, according to the conversion method between the agreement, the Web/WAP application service that the user can provide in the Internet arbitrarily by terminal accesses such as mobile phone terminal, PDA, notebook computer and desktop computers; For service provider that the WAP/WEB application service is provided and content supplier, the content of service can only be provided emphatically, thereby realize content being provided and representing separating of content, and then realize effective fusion of the Internet and communication network.In addition, the embodiment of the invention proposes the concrete grammar of two kinds of different protocol language conversion logics, makes protocol conversion become a kind of reality, rather than a kind of possibility.

There are problems such as complexity in mutual syntax conversion to the embodiment of the invention between isomery and the three big protocol suites in view of network entities such as terminal, network, application server exist, for example the mobile phone terminal model emerges in an endless stream, the network form has comprised 2G, 2.5G and 3G, and continue evolution; Unit have 36 in WML 1.3 agreements, the attribute number is approximately 2～3 times of element, the embodiment of the invention proposes to programme by xsl file based on the XSLT technology, corresponding transformation rule and response message content modification can pass through the XSL syntactic representation, need not large scale programming, can dispose fast and the response demand, and can be along with the evolution synchronized development of WML and XHTML; In addition, the embodiment of the invention adopts the XSLT technology to carry out the grammer mapping in to the processing procedure of response message content, and the operation of the dom tree of unconventional java or C language can improve efficient, flexibility and the extensibility of conversion.
