Embodiment
The present invention can use a hand-held device in the mobile data network.The example of this mobile data network is two-way personal messages net (for example paging), Cellular Networks, double-direction radio electrical network and PCS Personal Communications System (PCS) network.
Fig. 1 has to a computer network example of the two-way personal messages net of the gateway of the Internet for example.Should note providing the two-way personal messages net of Fig. 1 only to be used to illustrate principle of the present invention.Instruction of the present invention can easily expand to uses any wireless data communication system.
As shown in Figure 1, two-way portable terminal 101a represents personal messages net 100 mobile user devices to 101n.Portable terminal 101a to 101n usually with base station 102a to the 102m two-way communication, base station 102a provides the local station that network is served to 102m.The base station is with Regional Distribution, so that cover a messenger service district.Specifically, specify each base station, for example base station 102a is to each of 102m, the sub-fraction of serving whole messenger service district.Do not have expression among Fig. 1 be spread all over whole service area, to the one or more transmitters of portable terminal 101a to the 101n broadcast.An example of so two-way personal messages net is 08/542 at the sequence number of WeijiaWang, 860, the applying date is open in the patented claim (" co-pending application ") " double-direction radio data network (TWO-WAYWIRELESS DATA NETWORK) " of the pending trial in October 13 nineteen ninety-five, this application transfers universal wireless communication company, should also be assignee of the present invention with department.Combine integral body reference at this to the open text of this co-pending application.
LAN (Local Area Network) 107 inserts backhaul network 103 by backhaul interface 104a to 104c.Provide by Ethernet 108a and be coupled to distributor processes device 105a and the 105b of backhaul interface 104a to 104c, so that according to transmitting stage in the packet and application layer routing iinformation, come route to select application gateway 106a, 106b and the 106c of this packet to appointment by Ethernet 108b.Application gateway is as the information retrieval agency or as the interface of transmitting message between the system that uses different agreement.The application gateway of appointment, for example application gateway 106a checks the suitable action of content to determine to carry out of this packet.For example, a suitable action can comprise the initialization that is used for from the TCP that connects in the Internet of a host access information on the Internet.
If exist, then send it back to this request portable terminal through a link-local (promptly at the request portable terminal and send link between the home base stations of this request) from a bag of specifying application gateway.Otherwise, can provide response by One-to-All Broadcast or by " waking (wake up) a up " message, so that remind this portable terminal to set up a link-local, so that the response that transmits is waited in line in retrieval now.
The present invention relates to the application gateway of many types.Fig. 2 is the block scheme of some examples of the application gateway in expression one embodiment of the present of invention.In this description, the same unit among the different figure of accompanying drawing uses identical label, so that these unit of cross reference.As shown in Figure 2, divider 105a and following gateway communication: (i) application gateway 106a, it is a unidirectional gateway to other unidirectional message system that is represented by reference number 203 collectivities; (ii) application gateway 106b, it is called " information that claims (IOD) " gateway, it is to an information source, an interface of the online service of WWW, the out of Memory on the Internet or transaction services and enterprises for example, and (iii) application gateway 106c, it is the gateway to an e-mail system.
In this embodiment, each among application gateway 106a, 106b and the 106c can comprise that subnet closes, and it is to specify subsystem or the program that is used to carry out a specific function that subnet closes.For example, application gateway 106b and the 106c that is illustrated among Fig. 2 comprises PADL subnet pass 201 and storage and transmits subnet pass 202.For example, this subnet closes and can be realized by a CGI (Common Gateway Interface) (CGI) program that a called gateways is called when requiring, perhaps a built-in function can visiting as called gateways.For example, Fig. 2 represent storage and transmit subnet close 202 can the two calls by IOD application gateway 106b or e-mail applications gateway 106b.For example, storage and forwarding subnet pass 202 can be interfaces to a post office protocol (POP3) e-mail server.This server can also can be visited by a browser program by application gateway 106b by application gateway 106c by an Email User routine access.
Design IOD application gateway 106b is with the acting server as the interface of message net and WWW or the system of enterprise's " in-house network " that is equal to.IOD application gateway 106a carries out this interface task through the following steps: (i) from portable terminal, for example portable terminal 101a receives the IOD request to 101n; (ii) being transformed to standard HTTP (HTTP) request of using on the Internet with the IOD request (" PADL form ") that the application development language PADL that will be described below represents; (iii) the request of the HTTP after the conversion is forwarded to the site of appointment; (iv) receive the standard http response (for example common (plain) text or HTML response) that the HTTP after the conversion is asked from this point; (v) the http response that receives is carried out necessary any filtration of having asked or grammatical analysis; (vi) http response that filter or grammatical analysis is transformed to a kind of form that is suitable for wireless transmission, for example PADL; (vii) the response of conversion (for example PADL form) is transmitted to the request portable terminal, is used for showing or further handling.In the present invention, use data compression in the wireless transmission in backhaul network.
At mobile radio terminal, for example mobile radio terminal 101a when receiving a PADL form, calls " browser " application program so that this PADL form is carried out grammatical analysis to any one terminal of 101n.Fig. 3 illustrates the basic operation of this browser application.As shown in Figure 3, in step 301, this browser program carries out grammatical analysis to this PADL form, so that discern and set up the unit of this form.In an embodiment that will be described below, the unit of each PADL form is carried out one or more following functions usually: (i) this unit is shown on portable terminal, (ii) receive user input data (check box (checkboxes) for example, radio (radio) button, text box (textboxes)), (iii) format and the relevant data in unit (for example URL of Fang Wen site), these data comprise the Any user input data of reception, with as the part of the IOD request that will send to the IOD gateway with (iv) transmit specific instruction (for example filter request) to the IOD gateway.In step 302, browser sends control the unit of foundation to, so that each unit and form therefore can show on portable terminal.In step 303, if the input of request Any user data, then units corresponding and user work in coordination so that obtain user's input.In step 304,, then, be used to send to the IOD gateway by this IOD request of formula of formatting of the unit of this form if IOD request is produced by PADL form (for example the user is by next " submitting (submit) to " button).In step 305, browser makes this IOD request send to the IOD gateway.
Therefore, the present invention is under the situation of the burden that increases the weight of the wireless communication media bandwidth within reason; Visit to the Internet or intranet is provided in two ways: (i) compare with the standard agreement that uses in the present the Internet, the application protocol that the present invention uses is minimum; The (ii) data compression technique that uses in the backhaul network.Notice, although mobile radio terminal 101a is called " terminal " to 101n, but each of these portable terminals is actually a network computer, this is because each terminal is not to be specifically designed to any independent principal computer of visit, but the server and the database of any number that provides by the IOD gateway can be provided.
Notice that each the PADL form that sends to portable terminal can make this portable terminal carry out the existing capability of portable terminal arbitrarily, and make at IOD gateway or effective in any function that from the accessibility any server of this IOD gateway, can carry out.Therefore, the PADL form be can be aloft to the mechanism of each portable terminal " programming ".Therefore, each portable terminal becomes a wireless network computing machine.So, the new application and new function of unrestricted number can be provided to the user, need not is that reprogramming physics transmits portable terminal.And, for Web server, can provide these new application and functions, and not need on the existing WWW network server that HTML and http protocol have been asked, to force any extra requirement to the user radio portable terminal.
For being easy to ask between the standard HTTP request and between the HTTP/ of standard text or HTTP/HTML response and IOD response, carry out conversion and design PADL at IOD.Therefore, between many HTML structures, HTTP structure and PADL structure, can find one-to-one relationship.The example of this corresponding relation provides below.Although PADL realizes in bidirection pager that at first PADL is suitable for being used in the following manner in all devices that requires access the Internet.
PADL mainly concentrates on to relate to and calls on teleprogram (for example cgi script or script) functional, is provided for transmitting the facility of parameter and their value, and allows type number according to the show on mobile radio terminal.In the present embodiment as described below, the PADL structure relates to calling of " form " and cgi script or script.These structures are for particularly useful at visit information on the Internet (for example weather, news and physical culture etc.) and transactional services (for example bank transaction, stock trade etc.) at present.
Usually, utilize the mark in the hypertext document to transmit internal expression text (meta-text) information as HTML.For example, in HTML, at mark＜FORM〉and＜/FORM between definition HTML form, the corresponding shelves note among the PADL is＜f〉and＜/f.The HTML form is to be utilized in browser environment to gather variable and their analog value and to send to the mechanism of site to handle.If this PADL subnet closes the mark that runs into a unknown, then ignore this unknown mark.For example, can utilize HTMT＜form〉mark (describes the grammer of a mark: the selectable flag parameters of parametric representation in a. bracket (i.e. []) in the following description, by following regulation; Flag parameters among b.HTML and the PADL can be any order, except the flag parameters in HTML " CHECKED " or " SELECTED " parameter must be followed this type character; With c. "＜" of no use or "〉" any text of comprising all thinks text data, text data are not by decipher) the specified CGI scripting of " ACTION " field or the processing of the program HTML form of handling the site.＜form〉grammer of mark is as follows:
<form?ACTION＝“URL”[METHOD＝“get”“post”
“put”]>form?elements</form>
Should " METHOD (method) " field the identification mechanism that is used for transmitting parameter be assigned to three key words of the CGI scripting of site: " get ", " post " and " put ".According to " get " method, the argument (argument) of CGI scripting is appended to the URL character string of appointment in the ACTION field.According to " post " method, the character string that these arguments are used as in " entity-body " field of HTTP request provides.
Therefore, this PADL subnet closes and utilizes a corresponding PADL＜F〉HTML＜form of mark replacement〉mark:
<Ft＝“title”h＝host-id?c＝path?to?cgi?program
m＝gou>form?elements</F>
At＜F〉in the marker character, parameter " m " can be taked to represent HTML＜form respectively〉" get ", the character value ' g ' of " post " and " put " key word, ' o ' ' u ' of mark.URL to HTML " ACTION " field carries out grammatical analysis, and this information is splitted into " h " and " c field among the PADL.If occurred a HTML＜title in the past〉and＜/title〉mark, then specify PADL＜F〉" t " field of mark is＜title〉and＜/title〉title that comprises between the mark.
In html file, often using a HTML＜input〉mark is so that regulation is given the input value of CGI scripting.HTML＜input〉grammer of mark is as follows:
<Input?TYPE＝“hidden”“text”
“password”“submit”“reset”
“radio”“checkbox”NAME＝“name”
[VALUE＝“value”
[CHECKED]][SIZE＝“number”][MAXLENGTH
＝“number”>
Give in this form each＜input unique name of mark.If HTML＜input〉mark TYPE (type) fields specify " hidden ", then do not have the user to import and＜input〉mark is relevant.On the contrary, " hidden " HTML＜input〉mark obtains input value from HTML form itself." hidden " HTML＜input〉be marked with and help: the maintenance for the specified states variable is followed the tracks of; The title of the HTML form of CGI scripting is called in expression; Or default value is set for the variable in the CGI scripting.
The PADL subnet closes HTML " hidden "＜input〉mark is converted to PADL＜H〉mark.PADL＜H〉mark has following grammer:
<Hn＝name[，v＝“VALUE”]>
PADL＜H〉" n " and " v " field and HTML＜input in the mark〉" NAME (title) " and " VALUE (value) " field of mark is equal to.The PADL subnet closes ignores " hidden " HTML＜input〉" SIZE (size) " and " MAXLENGTH (maximum length) " parameter in the mark.
If at HTML＜input〉stipulated " text (text) " in the TYPE field of mark, then receive the text line of input.The value of stipulating in " VALUE " field is as the initial value or the default value of the input variable of stipulating in " NAME " field.The size of the line of text that " SIZE " fields specify shows, and the maximum length of the text that returns with form of " MAXLENGTH " regulation.
The PADL subnet closes HTML " text "＜input〉mark is converted to PADL＜L〉mark.PADL＜L〉mark has following grammer:
<Ln＝name[，v＝“value”][，x＝number]>
PADL＜L〉" n " in the mark, " v " and " x " field and " text " HTML＜input〉" NAME ", " VALUE " and " MAXLENGTH " field in the mark be equal to respectively." x " field is stipulated maximum length with byte number, and it can be used in the text that returns.The PADL subnet closes ignores " text " HTML＜input〉" SIZE " parameter in the mark.When showing a PADL form, the line of text of demonstration has fixing length.
If at HTML＜input〉the TYPE fields specify of mark " password (password) " then receive the text line of input.The maximum length of the text that the size of the line of text that " SIZE " fields specify shows and " MAXLENGTH " fields specify are returned with this form.Because character is input in this article one's own profession, so they show as " x " character respectively.
The PADL subnet closes HTML " password "＜input〉mark is converted to a PADL＜X〉mark.This PADL＜X〉mark has following grammer:
<Xn＝name[，x＝number]>
PADL＜X〉in the mark " n " and " x " field respectively with " password " HTML＜input " NAME " and " MAXLENGTH " field of mark is equal to.Should " x " field stipulate maximum length with byte number, it can be used in the text that returns.The PADL subnet closes ignores " password " HTML＜input〉" SIZE " parameter in the mark.
The PADL subnet closes neither replaces " submit " HTML＜input〉mark, do not replace " reset " HTML＜input yet〉mark, because optional software " submit " and " reset " button from the keyboard of portable terminal are provided.
If at HTML＜input〉the TYPE fields specify of mark " radio " or " checkbox ", then select to show a radio button or a check box for the user.At an independent HTML＜input〉can stipulate a plurality of radio buttons in the mark.Thereby shared same " NAME " field.But each check box is defined in an independent HTML＜input〉in the mark.The value of appointment is as the initial value or the default value of the variable relevant with this radio button or check box in " VALUE " field.
The PADL subnet closes this " radio " HTML＜input〉mark is converted to PADL＜D〉mark.PADL＜D〉mark has following grammer:
<D[s]n＝name[v＝“value”]>
This PADL＜D〉in the mark " n " and " v " field respectively with corresponding " radio " HTML＜input " NAME " and " VALUE " field in the mark is equal to.
The PADL subnet closes HTML " checkbox (check box) "＜input〉mark is converted to a PADL＜C〉mark.PADL＜C〉mark has following grammer:
<C[s]n＝“name”[，v＝“value”]>
PADL＜C〉in the mark " n " and " v " field respectively with " checkbox " HTML＜input " NAME " and " VALUE " field in the mark is equal to.In PADL, if do not select and one＜C〉the corresponding check box of mark, then this value does not pass to CGI scripting as parameter.If at HTML＜input〉be provided with " CHECKED " field in the mark, default value that then should " VALUE " field is " on ".For one＜C of prompting in PADL〉default value of mark is " on ", should＜C〉followed character " s " at once behind the mark.
At use＜textarea (text area)〉can provide the multiline text zone among the HTML of mark.In most of Web browsers, automatically for each HTML＜textarea〉mark provides a scroll bar, a HTML＜textarea grammer as follows:
<textarea?NAME＝“name”ROWS＝“number”
COLS＝“number”></textarea>
In the embodiment of this PADL, HTML＜textarea〉mark by have following grammer＜T mark replaces:
<Tn＝name[，v＝“value]>
Should＜the T mark〉" n " field provides and named text filed a kind of mechanism, and＜T〉" v " field of mark allows a default character string to be placed in the text zone.The multiline text district of a fixed size only is provided in the viewing area of portable terminal in this embodiment.Therefore, ignored value among ROWS (OK) and the COLS (row).
Can comprise one＜option by in HTML, using〉one＜select of label table〉mark provides an option table, and this selects to allow to select multinomial (" option ") of this table.Should＜select〉grammer of mark is as follows:
<select?NAME＝“name”[SIZE＝
“number”][MULTIPLE]>text/option
list</select>
If " MULTIPLE (multinomial) " key word, then allow at＜select and＜/select〉select a plurality of option tags between the mark." SIZE " field provides rendering preferences number simultaneously.
＜option〉mark has grammer:
<option[VALUE＝“VALUE”[SELECTED]>
[label]
Each＜option〉mark represents an optional object." SELECTED " key word represents that optional object is by default selection.[label (label)] field is＜option〉option names of mark.
The PADL subnet closes HTML＜select〉mark is with one＜S〉mark replaces, this＜S〉mark has grammer:
<Sn＝name>text/option?list</S>
In PADL, ignore " SIZE " field and be not supported in multinomial selection in the single table (i.e. " mutiple " option), because use＜C mark can obtain substantially the same result.
The PADL subnet closes HTML＜option〉mark is with＜O〉the mark replacement,＜O〉mark has grammer:
<O[s]v＝“value”>[label]
＜O〉" v " and " label " field of mark is corresponding to HTML＜option〉" VALUE " and " label " field of object.
In HTML respectively by＜br and＜p the interruption of nominated bank and section.＜br〉and＜p〉mark has following grammer:
<br[CLEAR＝“left”“right”
“all”]>
<p>
HTML＜br〉＜p〉" CLEAR " field in the mark allows delegation to interrupt around an image.
The PADL subnet closes HTML＜br〉mark and＜p mark the two all with " " character (hexadecimal value 10) replacement.In this embodiment, because do not support on-line image on the portable terminal, so PADL ignores " CLEAR " field.
At last, define a PADL mark＜R 〉, it closes identification with the PADL subnet so that be wave filter of http response appointment.Should＜R〉grammer of mark is as follows:
<Rf＝free?form?response?filtering
rules>
The example of wave filter that can appointment comprises: the wave filter that (a) is used for a HTML formal file is transformed to a PADL formal file; (b) be used to eliminate all HTML marks, and only return the wave filter of a text; If (c) provide http response, then select the wave filter of the column or row value of appointment with a kind of html table formula.
It is to be used to illustrate specific embodiment of the present invention that top detailed description is provided, rather than intended the present invention.Variations and modifications within the scope of the invention are possible.Stipulate the present invention with following claims.
