Technical field

The present invention relates generally to a kind of be used for dialling be the back-up system of formula internet communication and particularly relate to a kind of wireless group of system of making formula visit that is used for from mobile phone personal data management device that be customized.

Background technology

Three new inventions are ripe and improved communication and data practicality----mobile phone, personal digital assistant and the Internet.Mobile phone is being expanded its influence and business.The service of this type of expansion comprises: the beep-pager function of merging, Call Waiting, caller ID and the more recently mobile phone screen that allows text or figure face-to-face communication.The mobile phone industry has been developed a kind of wireless application protocol (wap), and it is supported in the mobile phone with radio modem integrated digital data.

Personal data assistants (PDA) becomes indispensable and all be useful to anyone by the professional personage of typical case just gradually.The PDA that occurs with various sizes merged want address, timetable, do tabulation, the application of expense and other individual service.Communication touches by a small screen and one normally that sheet or keypad carry out.Though common PDA has the black and white screen, trend just develops towards color/graphics.These two equipment of mobile phone and PDA are supposed to be incorporated in the handheld unit of an expansion, and it will keep the individual's application that is closely related with the user and allow the user to link to each other with the world through wireless connections.

The Internet provides diversified data source and performance.HTML and XML are used to encode and transmit the standard language of these data sources.The Internet has formed a kind of global communication medium that make millions of people can share information and manage business electronically.Though its principal traffic route device is visible to be desktop computer, the main means of current accessed the Internet many sense organs that become, internet communication also will change the sort of mode.The Internet provides as the music of CD now and transmits the message as answering equipment.The main capital of the Internet is the ability of the varied information of visit and the search engine capability of searching these information.The major defect of the Internet is because through its caused ever-increasing delay of data capacity and for using needs that connected the computer access the Internet by the Internet time.Just the radio modem of portable computer is just entering general practicality now, but these handheld units than the expansion of anticipation more bother.

The speed that transmits when data increases fully that the Internet has just become a kind of common communication medium when overcoming the trouble factor.When personal visit is that then the Internet uses and is restricted to dialogue and data access when being formula modulator-demodulator from 14.4 to 56kbps speed by dialling with scope.Moved on to ISDN, ASDL and cable along with non-commercial uses, velocity interval is from 128kbps to 2Mbps, and then the use of the Internet has increased and the application such as audio frequency, mobile video and other are used in real time has become more general.

Radio communication speed is not mated wire speed.Current wireless speed is 9.6 to 33.6kbps, and speed just is planned to be lengthened to 2Mbps from 384kbps after 2002.Therefore, wireless Web surfing is limited than the delay during the more the Internet of connected reference uses.

Format most current internet Web resource for the visit of personal desktop machine or laptop computer, in the resolution scope of this display and/or LCD (LCD) from 640 * 480 to 1600 * 1200 pixels approximately.Personal computer can have a big capacity hard disk driver and a sizable random access storage device (reaching 614 Mbytes).The window of each HTML webpage is by the memory size very big (reaching several Mbytes) of the extensive opening and a page.Desktop computer user's Internet Server is supposed the high bandwidth that is connected with to workbench usually.In fact, the bandwidth requirement of the Internet has promoted the communication technology and constantly provides how possible path to desktop computer.

Now begun to make great efforts to utilize the mobile phone of expansion to visit the Internet with visible screen.; current wireless web surfing suffers the long-time download time of page or leaf in the possible interrupted character of slow wireless data rates, wireless connections, the graphical-set, waits for the cost of the information of passing the Internet when the Internet becomes very congested, and suffers an insufficient graphical user interface.

Some effort that alleviates those situations is concentrated on the wireless communication capacity.Global system for mobile communications (GSM) is an extensible circuit-switched technology, and circuit-switched technology is the basis of great majority expansion.Wireless application protocol (wap) is optimised to come current generation work with confined display capabilities and digital radio system.WAP be counted as the leading standard of a centre of the third generation (3G) ability.Among the most interested 3G development of mobile visual communications, there is first enforcement of the packet switching in GPRS (GPRS) and bluetooth, GPRS, the GSM to allow the user to use Internet agreement (IP) to transmit and receive data with the speed that reaches 115kbps.This service is very efficient in its use of shortage frequency spectrum resource and will allows the feature such as " virtual permanent connection " to data source.Bluetooth is a kind of low-power wireless technology, and it will allow equipment to comeswap data 30 meters scopes far away to reach 720 speed.Bluetooth equipment can be grouped in the subnet of local zone.Trial provides any system of service to work in this development program of GSM3G development for mobile visual communications.

Required is a kind of like this method: make hand-held mobile Web browser occur coming with so high data rate and working, and have a response fast like this, it has compensated the traffic congestion of the Internet.The quick renewal of information, user-friendly graphical user interface and for the webpage of smaller screen covert customization must be in handheld unit effectively.

Summary of the invention

Support mobile Internet to visit needed system with two focuses from the handheld unit of expansion: speed and certain content are the center.These two thereby all to place the content of user expectation by the server that physically approaches the user as far as possible serviced.The speed that need be in the supporting business level compensates the cost structure of radio communication and the limitation of low bandwidth and handheld unit screen.The form that needs certain content to translate easily according to the quilt of the speed of replenishing service presents information widely.The speed service not only is positioned in the handheld unit but also be positioned in a self-defined server that is used for ambulatory handheld Web surfing.

According to the present invention, a kind of method that begins to search for is provided, described method is carried out in a handheld device, this handheld device has merged the multinomial function of mobile digital phone, screen, input equipment, loud speaker, processor and memory, and described method comprises: store at least one prior searches theme; The menu that shows at least one theme that is proposed at first on screen, described at least one theme that is proposed at first comprise at least one at least one prior searches theme of described storage; Reception is selected by the theme of input equipment input; Show at least one menu narrower, follow-up theme, described at least one narrower follow-up theme depends on that the theme of described reception selects and comprise at least one prior searches theme of described storage at least one; Repeating described reception and step display selects to be received up to a theme the narrowest; With on a Radio Link, the basis of a server as search selected to be transmitted in the narrowest described theme.

A feature of this new system is that structure goes into to hand an ability in the unit, produces searching request, and it correctly reappears the information of being wanted from network.These searching request increased available wide region function of search and guide the user correctly to define needs so as restriction for the collision quantity of that request.Another feature in the handheld unit is a fast connection; The service that mandate user and Ta is identified as handheld unit is being connected and server is providing for the first time and connects.Another feature in the handheld unit is the ability of translation mark, and these marks allow this handheld unit just to download the data that change and keep static data in the local storage.

Speed also means server, and this handheld unit has special ability to the main entrance of the Internet.One of these abilities are to be the conversion of page of desktop computer form an ability of ambulatory handheld screen format.This can be a page to one of many shieldings directly conversion or by a customization conversion of informant's approval, and it has optimized the demonstration of handheld environment.A kind of device of another ability shielding that to be visit customize for handheld unit is no matter and this screen is resided in the server place or on other database of the communications access that is comprised the Internet.To be that handheld communication is professional guarantee that each emission is quantized and be full of the whole screen in the handheld unit and keep a running status so that start Control on Communication (communicationsride) by a wireless service outage another server-capabilities.In display speed one main the improvement is taken place, because server can directly be visited a many-sided database, this data base manipulation is based on historical use of user and information selected and that need to have planned is full of.Such database has been avoided needing to wait for that complete internet access transmits data and gives handheld unit.When being updated for other parts of the Internet based on the data of the page, database is kept current in real time.

A specific user's server is a member for a cover specialized server of mobile subscriber's customization.High-speed interconnect between these servers allows the formative especially information of quilt that becomes one all available to everyone.Search engine has been distinguished the search that needs internet usage and has been improved the search on the specialized server group of being concentrated in of reciprocation speed.

For hand-held mobile subscriber supports the feature of certain content to comprise to allow the content provider to propose the ability of the renewal of their desktop computer webpage and makes that renewal formatted for desktop computer and hand-screen.The ability of being gone into these application by structure comprises marked capacity.The dynamic area, they are distinguished mutually with the static region in the page, page reformatting so that on most hand-screen, be fit to.Similarly, for selecting not provide hand-screen on the internet but provide the speed that those information provider of approval, quick self-defined transform engine in advance are provided to improve the screen message visit.Based on user's visit and the grouping information that information is remained in most of addressable mediums is a performance that is performed.The ability that conventional desktop computer webpage is converted to a handheld format is provided, and its use is limited on the explicit request of handset user for conversion.Ability in the renewal of information that artificial intelligence technology is applied to continues this visit and improves after an initial subscription information of user.

Embodiment

Along with having become gradually, people rely on E-mail service, remote access so that be organized into the scholar and, then provide the radio telephone of mobile access and hand-held manager to become useful instrument gradually to these resources based on the business of the Internet., the emphasis in the mobile communication industry of today is just moving to many senses from single sense reciprocation and is interacting, and the manufacturer merges in the radio telephone an optional front end (frontend) as those phones to screen and modulator-demodulator.The current low data rate of radio communication the third generation that is proposed (3G) and Bluetooth technology some year in modified up to 384Kbps, this is the global specifications of wireless connections.These improvement are designed to allow wireless device to operate, carry out one in noisy wireless environment to confirm fast and use that a hopping scheme produces link and strengthens., even improve for these, wireless data rates still limit such as web browse and full action video image-watching application.

The requirement that mobile web browses comprises a high data rate, respond fast, avoid that the internet communication amount is crowded, the instant visit to information, user-friendly GUI and the web page or leaf that designs with maximum information content and less text.The present invention uses wireless existing and developing the increasing as the basis that effective mobile applied business is provided of current mobile phone, and these move effectively that the web that uses such as Email, facsimile machine, rapid data retrieval, information search, individuals and organizations' data browses and real-time huge data demonstration and so on.

Fig. 1 has illustrated acurrent webpage 10 that is provided for desktop device.Webpage 10 is characterized in that many-sided application: text, be designed the suggestion search coverage and the esp. classification of some littledynamic area 12 of new data more regularly.Dynamic area 12 can comprise that news in brief, market value of shares or its dynamic property are interested those specialized information of specific user.For a mobile business user, this type of multidate information can comprise his company inventory level, number of times or other information specific turn around.Its feature of the desktop computer page further is to present the information of the data that extend beyond ascreen.Scroll bar 14 allows to check the more multidata and next form with a kind of electrical form ability downward or that laterally roll that offers an opportunity.These abilities are to prevent for a kind of of mobile subscriber's function with the small screen in the environment of the unreliable communication that leakage may occur at any time.For the mobile subscriber, receiving needed data with the increment of the single screen that can guarantee is preferably.

A kind of handheld unit (HHU) that has merged a radio telephone, color video screen, input mechanism and programmable, intelligent will be available in the near future so industry trend is being advanced.The present invention includes in order to use HHU multiple-effect and attractive in appearance and in this HHU and in the program of server location place operation.

Fig. 2 has illustrated system configuration according to the present invention, and the mobile subscriber who is used for being supported in a geographic area carries out the face-to-face communication based on web.A plurality of such structures are used to realize supporting to spread all over a user in the wide zone.This system's support is from not utilizing web and based on the communication in the pre-specified data storehouse of the face-to-face communication of web.Amobile subscriber 20 has a small screen and is connected to network by wireless communication link dialing 21.Mobilesubscriber 20 is connected to a network, and this network can be by the expansion of a network ofdesktop computer user 18 uses.Onhandheld unit 19, use 22 illustratedmany server 24 positions that are applied in by quick search and moved and ancillary equipment.Directly be directed to from the connection ofhandheld unit 19 thismobile subscriber 20 is distinguished an information service provider (ISP)server 24 that comes from desktop computer user 18.Ispserver 24 provides specific capacity for the mobile subscriber and allows mobile subscriber's 20 visits thatdesktop computer user 18 available all are served, such as theE-mail service 26 by the Internet 25.Specific concerning the mobile subscriber is such as the service (RuleInternalDatabase) of 80/20 regular interior database (RIDB) ofacceleration search.Database 28 is increased by a search engine, and this search engine can access internet moveparticular station 30 and the Internetdesktop computer website 32 that can be converted into mobile form 34.Search engine also provides the visit of specific mobile Internet content supplier (ICP)website 38 of Intranet (Intranet) or 36 pairs of reflections of secure internet ICP desktop computer website 40.Alternately,effective conversion 42 of the specific desk-top machine information 44 by ICP is provided, search engine is visited this information.

Ispserver 24 uses amapping server 46 to follow the tracks of the specific data of the position of all thislocality 28, Intranet andsecure internet 36, and these data have a dynamic component that is stored among the 20/80RIDB28.The renewal ofmapping server 46 management data availables.For the information that is stored by this locality,mapping server 46 and inside of RIDB28 use morenew template 48 provide reliable renewal.Alternately,mapping server 46 receives andmanagement update 52 and 54 from various updating the equipment by the Internet or Intranet50.

Figure 15 has illustrated the more such systems on wireless network of focal attention force rate internal system running.Radio network gateway 400 provides connection between the wireless device the radio telephone on being connected to traditional PD A402 or wireless PDA phone (HHU) 404.Radio network gateway 400 is connected tohome server group 406, and its information source goes out toequipment.Server group 406 can be to cover the individual system of 80/20RIDB and other service or can be the network that the system of performance is provided for this zone.The server group is connected to theapplication module 408 of being responsible for these all special service of system.When server group and application module can not be able to not provide needed information, if the Internet 414 of the Web416 of their access search webpages was perhaps during user's privileged trading, by theserver 412 of corporations of asecurity gateway 410 visits.

The high speed that Figure 16 has illustrated the regional composition that forms this system connects.By the high-speed intelligent link 42l that uses landline, optical link or the high-speed radio such as GSM or GPRS to connect, the server in each zone (such as Hong Kong 420) is tied to relevant zone, such as China 422, Taiwan 424 and Singapore 426.These links make in this area server can with a kind of transparent way shared data therefore between them data do not need to be replicated.The part that these high-speed links 421 are not conventional the Internets and by the data that they are visited do not suffer those the restriction the Internets delay.Similarly, because they are dedicated links,, on high-speed interconnect, do not need security gateway or VPN(Virtual Private Network) agreement so they are parts of private network.Some regional servers can be born aninterconnection 438 that keeps with other areas (such as Japan 430, Korea S 436, the U.S. 432 or Europe 434).Remain special-purpose interconnection and be at a high speed though these connect 438, because to the distance of visiting their data and the processing load of the increase such as translation, then shared effective use of the mass part of these databases is limited.

The block diagram of thehandheld unit 19 that is used bymobile subscriber 20 as shown in Figure 3.Unit 19 uses radio frequency (RF)signal 60 that is received by an antenna andRF receiver 62 to communicate by letter, and its decodeddevice 64 decodings become or voice or data and control signal.Be fed to CPU66 from the signal in thedecoder 64, its also withexternal memory card 68,flash memory 67, display device 84 andinterface card 80 interfaces.Handheld unit 19 keeps itsloud speaker 82, display screen and input button (not shown), and as what presented on a PDA or mobile phone usually, buthandheld unit 19 has than a standard P DA or mobile phone strong functions more.In case radio communication is established, then received signal decoded in case definite they whether be audio signal, it is sent to the telephony feature that is combined in the handheld unit, perhaps utilizes the modem portion ofdecoder 64 to come they of decoded digital then.Containmemory 68 and CPU widely inhandheld unit 19, this allows for peak response and speed many application to be positioned among the HHU.

Because the very big speed of improvement, GPRS allows to use standard browser application at HHU place rather than is the self-defined application that customizes of some signal post slowly of conventional wireless environment.In addition, GPRS allows the application such as the stream video that is utilized by the PDA phone.As shown in figure 22,server 24 reappears the video that flows out from private database (being 80/20RIDB28 in this case).Server is divided into the grouping that sends byGPRS service 480, for example P1, P2 and P3 to video.These groupings are launched into other transmitter 140b-140h as queue command from source antenna 140a.Receiver 140 can use the GPRS agreement to rebuild from the video stream in those groupings as user 19.Be used in high data rate in the GPRS communication and allow the delay that do not present on the internet from the transparent reconstruction of the video stream in the grouping.

An application on handheld unit is programmed discerns and translates HTML and XML form, is used for display web page and by standardized demonstration and command lanuage.It is the establishment of screen of webpage subclass that this performance has helped, because this conversion needn't be managed protocol changes.In addition, wap protocol is utilized when being suitable for the communications portion of managing this unit.Fig. 4 has illustrated the function that is included in the handheld unit.Handheld unit 19 be centered in haveloud speaker 82, on thedisplay screen 92 ofmemory 68 and modulator-demodulator 64.The decoder that these equipment allow to be used forvideo 94, figure andtext 96 andmusic 98 together for the user decoded results presents to suitable input-output equipment.Modulator-demodulator 64 is also connected toRF receiver 62 so that receive input with radio from one of manyMobile Serveies 100 that institute's request msg can be provided.

Replace structure for one group and be built in the handheld unit, these structures have bluetooth (short-distance wireless lift-off technology) communication.Therefore the standard modem of the unequipped GSM of being used for of some handheld devices and RF receiver can't visit the legacy system server.Other these handheld devices not only have the conventional wireless receiver but also have Bluetooth communication and be programmed the effect of playing home server.These server handheld devices receive from the information request in the handheld device of bluetooth only and this request and issue system server.When this information was received, it was delivered to the hand-held of these data of request.Replacedly, use a hand-held meeting of bluetooth for other participants, server is hand-held can to work as the link to system.To only need a phone to connect for such meeting, and all participants be visible and handle this data.

Using as this another one that moves the equipment part of web surfing is that search is used fast, and memory exists in the handheld unit, as illustrated in fig. 5.Search service first offers the type of user profile, and the user wishes the conventional option of replacing of also search usually.Thisfirst menu 110 adapt to cause customization so that forexample enterprise 114 consult the stock of user's commercial affairs.In this example, in case the user has selected an input, mapping 112, thennext screen 120 further limits this search, and providing is this user interest known target, such as Asian countries, is provided though enter the option of a diverse location.In this example, option Hong Kong 122 is selected, and implements a narrower search by present afeature menu 130 in the zone, Hong Kong that reappears from the memory of handheld unit.By search sequence is stored in promote to operate in the hand-held handheld unit in, an on-screen menu at any some place such asscreen 130 can be downloaded to this handheld unit from server.Along with search engine becomes when a user's search pattern is familiar with gradually, thereby the best mode that it will advise working out a search obtains the information expected more quickly.By using the transmission medium of voice, progressive will loss the in menu search as these suggestions.In case the user has selected a specific region in the area of having selected, in the example walking 132 in red-letter day, then search is submitted to the search engine that is present on the server.

Because search is narrowed down, so hit at the server place that quantity will diminish and the interactive quantity by Radio Link is minimized.This information specific is provided fast.When requested information was found at the ICP place that mobile form is provided, it is formatted to be used for this handheld unit screen and to launch and utilize symbol rather than word, all is possible anyplace.Search engine can be to provide an important factor in the response in good time to quick search application, and this will be described in detail in the description of search engine.

Fig. 6 has illustrated the connection ofhandheld unit 19 by Radio Link 140 pairs ofmobile web servers 24 of installing in the local reception zone everywhere.Connect shake hands fast contact stipulations and convenient of of carrying out at illustrated in fig. 7 this byhandheld unit 19 and server 24.Importantly meet an affirmation time target of 10 seconds, that is, carry out this contact stipulations rather than carry out of shaking hands fast at the server place by an other equipment in the Internet.

Connection fromhandheld unit 19 has merged the enough information that comprises radio telephone quantity and account sign indicating number so that allowserver 24 call identifying persons 220.Theseidentifications 220 comprise: differentiate user, concludeed a contract or treaty professional of authorized user and the security permission of setting up user's needs in advance.For those users that set up such as the commercial operation of the safe and reliable electron event of needs in bank, finance, telecommunications, amusement, health, education and corporations' information utilization or the like field, this system has merged asecurity gateway 410, as shown in figure 15.Security gateway 410 is realized three ranks: safe and reliable socket layer (SSL) connects, based on the checking of password with based on the end to end security of electronic identification.Security gateway is that Public key infrastructure (PKI) activates, and allows the mobile subscriber to utilize their the individual private key and the Public key of designated company digitally to sign and enciphered message.

The fast signal exchange also determines whether have a quilt to interrupt 222 calling recently, at this, an interruption is defined as not finishing a normal sign-out agreement here.If do not interrupt here, so the user be welcome 232 and server waitinput 228 from the user.If calling in the past is interrupted, then server determine whether before to have launched 224 a full screen.If a full screen is not sent out, server repeatsprevious emission 230 and waits user'sinput 228 so.If a full screen is sent out, server sendsnext screen 226 in order so, and perhaps, if there is not next screen here, then server is welcome this user and waited this user's input 228.By this mechanism, the obstacle that wireless environment is presented of shaking hands fast minimizes, and allows the user to manage his commercial affairs easily.After connect setting up, mobile web server provides the visit to specialized performance, such asmobile search engine 144 and to visit and so on fully of the Internet 146.

Be combined in hand-held in and locate as shown in figure 18 a customer location with the numeric area map that an applications exploiting of the application integration of shaking hands fast provides by GIS-Geographic Information System (GIS) and GPRS performance.The map inarea 450 increases with branch station location 452.When the user called map function on the handheld device, GIS information was used to select the map area that will be presented.This allows user's request local service concerning his position, such as the road between cinema, shopping or two positions.In addition, the user checks that in advance (by a snip or animated advertising) do not need to specify their title by the people that serves that these nearest suppliers provide.The user can subscribe an informing function based on the geographical position simultaneously, such as traffic notifications and weather forecast.

Operating among Fig. 8 ofmobile web server 24 is illustrated.Theserver 24 that has merged asearch engine 144 and a 20/80RIDB database 28 makes formula modem interface 150 be connected tomobile subscriber 20 by dialling.156 data of receiving are converted into handheld unit form based on screen bytransform engine 34 from the page of text form from the Internet by server 24.Because in the data on the Internet 156 in most of the cases is under various usage license agreements, so transformengine 34 will just just be called under specific request of the mobile subscriber 20.Therefore, when being found on the Internet 156 bymodule user 20 information requested,server 24 will send first message and whether wish to have the information that was converted tomobile subscriber 20 these users of inquiry.Have only whenline module 20 is asked the conversion of a specific webpage clearly, just will be converted 34 from the data of that page and be mobile form.In fact, once meet with this, then the data on these internet pages just will be changed, but the page that is converted will not be shown, unless just be requested to show it.This timing allows conversion instantaneous appearance concerning the user.

Mobile Server is necessary to be alocal data base 28, the information that it is established-promptly wants based on 20%/80% pattern 80% signal source 20% in obtain.Along with server is suggested and mobile subscriber's booking service, 20/80RIDB28 loads with information.Fig. 9 has illustrated the flow chart that is used forprestrain 20/80RIDB28.Just be planned as server, the routine information that will become a priority is determined and is loaded in the database 240.The selection of information will be based on experience and targeted customer's local commercial affairs and judge.Before the user is requested, the geography information type will be determined 242.Being exemplified as of geography information type: map, weather, commercial proposal and transporting equipment.Along with the user adds in the business, then they provide about their target geographic factor and select 244 (zone and information types) and their information specific to need 250 information.

Study Web server and mark browser are utilized to load in addition the 80/20RIDB database.User is during for the first time by the new webpage of one of learning server visit, and learning server is remembered all details of this page inside, marks in this page and recording user is visited time of these data.When the user returned this page, learning server was checked return time and check whether this page had been modified since this user is visited it the last time.If a change has been arranged here, then the mark browser is new information and the old next high-speed cache that presents total page and update mark browser to the user of merging.Because most should being reproduced from local cache of this page, so the access speed of this webpage is with modified.New request is added to database 252.

System continues to monitor normal requested data and then upgrade 20/80RIDB254 when needs.Time when system also checks user's request msg.If this class request takes place regularly or at a special time place, then learning server is provided with a notice.This notice makes just in time this on-screen data of being asked regularly of visit before user's rule request of learning server, and in this way, database is fully upgraded and the response time is enhanced when user's request msg.Be used for often being requested rather than locate requested screen a particular moment, learning server is provided with the notice of one-period so that keep renewal for the database entry of that screen.

According to public cimmercial practice, indexed and be labeled in the zone of each screen that is stored in the information of 20/80RIDB44.This mark is discerned these zones and the regional time that last time was updated.The purpose of mark is the transmitting range that is used for reducing between handheld unit and the server.When screen was accessed, system was learned and the mark stagnant zone.A stagnant zone mark indicates this zone no longer need be examined for renewal to logic, further quickens user's dynamic data.

Though annotated logic is arranged in server or handheld unit, the operating sequence that it is performed in handheld unit will be stated by auspicious at this.Whether handheld unit of server identification has the marks for treatment of enabling marks for treatment during connecting and expects that just carrying out mark with a handheld unit that therefore provides selects to communicate by letter.In response to a data request from a mark identification handheld unit, server will be a screen (rather than whole screen) emission mark.Handheld unit this mark and and last time update time in each zone with from this screen of handheld unit request last time the mark of storage compare.If a zone just has been updated since its last time is requested, then handheld unit will be asked the zone of this renewal.This handheld unit will be from new field and is still set up screen in the unconverted field its memory.If no longer in memory, then whole screen will be requested previous screen.Because only disabled data are sent out from server in handheld unit, so screen is set up quickly and the transmission time often is lower than the gate item.

A virtual individual database (VPD) is a memory block of user's special use, and it works and resembles the webpage of a special use.The user is assigned with the space of how available about 20Mb.The VPD relevant with 80/20RIDB saved and comprised these type of common read-only data such as user account number, e-mail address, component software identifier, file server, printer address, web page address and digital certificate.May be archived among the VPD such as electrical form that just needs when the meeting or the more interim data the document in addition.Because VPD is treated just as 80/20RIDB, so all addressable this information of mobile subscriber when needing whenever.Figure 19 has illustrated the tissue of the VPD the when classification that is mapped to access screen when theme is organized.

Being the information of passing PDAphone user can be issued at many signal sources place.These signal sources of minimum customization are to be present on the Internet those with the computer page form.In order with intelligible form this data to be rendered as the PDA screen, the page must be through a conversion process, and because possible license issue, the user must ask this conversion clearly.This system provides a conventional conversion program, and it is translated page HTML sign indicating number and each conversion of page is become a plurality of screens.This routine conversion program is just moved after this page is reproduced by the Internet.Therefore, possible the Internet postpones and the transfer process both has postponed the transmission of this information.If the specific webpage of information often is requested, then this system will learn this custom (as previously described) and spontaneously reappear and change this page., the user will still need to ask clearly this conversion before the transitional information screen is presented.

But the information source that HHU more than is fit to only provides the workbench page participates in by ratifying a conversion process in advance.By remove the approval step then subscriber response time modified and by conversion module then screen quality by modified.The transformation applications of utilizing this system to provide has merged some template that is customized in addition by the informant.The page-map that this provides one group of self-defined conversion module and offered the template of being supported by the informant to this system.The screen that is converted is not stored by this locality usually, but is produced according to request.Yet if the specific webpage of information often is requested, this system will learn this custom (as previously described) and spontaneously reappear and change this page.

A relevant informant provides information with the page and two kinds of forms of screen.In one embodiment, the informant only keeps page info at the remote site place, but any change all is transmitted to this system.The information of screen formatting is maintained in the fast access database, or 80/20RIDB, or is connected to a server on the center system by local area network (LAN) or high-speed communication.Conversion module is applied to the page of each change and only preserves screen and changes.Because system keeps these screens, so above-mentioned marking operation can be applied to further streamline operation.

This system keeps its information with the form of screen.This information, such as local map, local weather or the like and so on, if often accessed it be stored among the 80/20RIDB.Otherwise it is stored in the secondary server of next-door neighbour's main system.

Referring to Fig. 8,, allow the application of the renewal of the page of PDA form to be provided for ICPs because the many data that are stored among the 20/80RIDB28 are dynamic.Mapping server 46protection 20/80RIDB28 are not subjected to unexpected thedeterioration.Mapping server 46 comprises an index to all screen format data, and its mirror database 152 to all dynamic components ofspecific Mobile Server 24 and 20/80RIDB is unique.Any information that is updated in 20/80RIDB28 at first is updated in mirror database 152 and is transmitted toentire database 28 then.One is upgraded ICP virtual private the Internet, reliable interconnect net or local area network (LAN) 162 by as shown in Figure 8 and records in the mapping server.This daily record allows the ICP renewal only the more new template of its data to be conducted interviews.When ICP finished this renewal, it used a password to further this incident of checking to finish.This renewal is written in the mapping server memory 152 then.Locate constantly after a while at one, data will be transferred to 20/80RIDB28 from mapping server mirroring memory 152.

Alternately, ICP upgrades its operatinal data storehouse 160.It records in the mapping server and the notice of information and renewal 162 is sent tomapping server 46 by the Internet or local area network (LAN).After mappingserver 46 had been examined ICP, it extracted this change information and upgrades dynamic data base 152.This process frees the information that guarantees simultaneously among the 20/80RIDB to ICP from only upgrade an on-screen data storehouse be reliably and consistent with the operatinal data storehouse.

Because ICP is not directly connected to mapping server, thus an interface that is used to upgrade be provided, as shown in figure 10.ICP54 provides renewal to mapping server 46 by a reliable the Internet 202.Mapping server 46 specified datas in 20/80RIDB28 where and change record 212 in database 28 so that mobile subscriber's response is distinguished order of priority in information updating.Be used for the instrument that conventional web is converted to the handheld device page is called as intelligent updating mapping window (IUM window) as Figure 17 explanation.This instrument provides stencil design to help the initial creation of the handheld device page and the renewal of the existing page.It also increases template database according to designer's individual character of this instrument of use.An IUM window 440 of a particular type screen as shown in figure 17.It comprises that the preview area 442 that the handheld device screen of display message checks, the Title area 444 of prompting input are used for an input area 446 and an image file zone 448 of input text.Other templates can comprise graphics field, the input of mobile image and interaction region.When every next newtype screen is created, then be saved with its particular design person or the relevant template of content provider.Except adapting to the format of content needs, for the consistency of target handheld device then the IUM window also to check the screen that all are designed.These inspections will comprise relevant total page-size of expecting, the video content size and interactive inspection when a user checks this screen.The IUW window run in the network that comprises the Internet, local area network (LAN) and the many positions in VPN in.

As shown in figure 11, for the data that stem from isp server itself, inside morenew template 48 is utilized.This upgrades does not need mapping server, but data directly is delivered among the 20/80RIDB28 and exterior I CPs54 utilized a renewal mapping window 210 that provides to upgrade before information is delivered tomapping server 46 by network.

Thereby 20/80RIDB 28 is the fastest sources satisfies the request from the mobile subscriber., all information can not be stored among the 20/80RIDB28.Known the Internet has because the delay that router, cross-over connection and its length cause, so each Mobile Server merged a local area network (LAN), its it be connected on the selected mobile ICP server.This kind server comprises to be provided from those of the data of public internet and individual database.Figure 20 has illustrated how the dexterity search of information checkedindividual database 462 andlocal data base 464 before checking other zone 466.Check that other zone will be included in and carry out checking each local database in the area 468 before other areas 470.Search on the internet will be fit to this program.

Found local ofsearch engine 144 trace informations and choose the fastest route of this information.As shown in figure 12, the website of ICP44 can be on the local area network (LAN) 36 identical withMobile Server 38 or on a reliable the Internet.According to a kind of form, for the mobile subscriber formats information inscreen 38, at this, screen has reflected workbench user information available 40.Alternately,workbench information 44 is direct information available only, buteffective transform engine 42 will be provided as the information of each screen formatting.Effectively the advantage oftransform engine 42 is: ICP has verified the conversion of workbench information, and the user just needn't clearly ask this to change so.

The search engine of optimizing for radio communication as shown in figure 13.Speed search is applied in the front end of search engine.In case receive a searching request, then search utility as shown.Search engine is at first searched expectation information 264 in 20/80RIDB28.Because retrieve data does not need access to netwoks from 20/80RIDB28, so this is the fastest visit.Next preferred information source is the ICP mobile site on the local area network 266, after local ICP mobile site, the workbench website that is equipped with effective transform engine be next preferred 268, if it is found that information does not have in locally-attached information source, then a search on the internet is issued 270.From the response in by effective data converted storehouse 274 or standard the Internet the information 276 and preferred network Mobile Server 272, the result of this search is further analyzed after the conversion of request in utilization.In each case, search engine returns a screen or tells user profile to find to the user.

Learn that whensearch engine 28 which workbench internet sites is frequent when accessed, it will visit this website termly, and translation data also is stored in it among the 20/80RIDB.The user will still need clearly to ask a conversion, but needn't pass through the Internet by outstanding message after making this specific request.

According to the coverage of the analysis of each user's behavioural habits records (BHL) being expanded 20/80RIDB28, as shown in Figure 14.On a basis of carrying out, each URL by internet access is recorded in the BHL database 300.Determine the time interval with pre-, based on user's request and the variable such as performance guarantees, the BHL database analyzed as being such as to a URL access frequency with to the classification a URL access time.For surpassing other each classification of predetermined threshold level, the response action such as storage URL dynamic component is issued 304.For high utilization rate each classification that is time correlation, the fast storage of base is issued in the time of one, except analyzing the URL visit, analyzed so that search those classifications that have from effective variation ofprevious use rank 306 to the visit of 20/80RIDB to data so that being increased among the 20/80RIDB.The BHL log analysis is stored by the user as a summary and resolves a datum line of 308 as next.

System sets up on behavior learning so that carry out the just in time timely access process of data, rather than for good and all fills 80/20RIDB.This process comprises data mining (DM) stage and data warehouse (DW) stage.In stage, this process monitoring is each user's surfing on the net as mentioned above at DM, sets up to comprise that URL visit, access time and the time interval between request or the like are at interior surfing configuration file.Termly, search thereby the data of being exploited are analyzed for the very rare still abundant predictable pattern startup DW stage of permanent 80/20RIDB storage.In stage, expect that at a time requested website is asked in advance and is stored in the home server so that improve the response time of feeling at DW.It is to be this user's " interested " not request msg that this process also is used for pushing by precognition in the stand-by moment.

The email type of being supported by the PDA phone is more extensive than the other technologies that have been restricted to about 100 character informations traditionally.So because screen is supported the file attachment such as electrical form, file, image, video file and audio frequency by the message of seamless renewal PDA phone support indefinite length.Chart in the PDA phone and video support allow the full communication of relevant information.

Figure 23 illustrated the literal display screen on themobile phone 520, may be in display screen under the WAP522 and the contrast between the display screen on the HHU524.But the chart ofmap 524 shows to be made its direction that can not only be sent to the three unities transmits relative distance, candidate course line and available service on those course lines.Similarly, the Email on atext display screen 526 does not provide fail safe and presents mail with a kind of continuous form.ThoughWAP Email 528 is considered some fail safe clause, to such an extent as to its display screen is limited very much and can not formats the mail display screen.On the contrary, HHUEmail display screen 530 provides fail safe 532, shows that with a kind ofform 534 that organises the message of wait state and prompting send message andreply 536, and it is convenient to work.

Two examples will illustrate by the progress in the wireless communication technology and the present invention are merged and potential improvement service: online fight color and online stock exchange.Each of these application all needs to move in advance so that allow to continue finishing rapidly of action.The user must know that they will perhaps roam into the expansion of network range in network.This defective is very big one when being performed when foregoing regional communication provides.Type-usefulness that the user then needs to register expectation information comprises the contest database or the registration of each stock database of specific support database of the present invention.Last preliminary step comprises the account of the permission incident of setting up (fight coloured silk or transaction).Fail safe clause of the present invention guarantees that these incidents are done reliably and safely.

At these movable traditional approachs of management, carry out their current mode and in Figure 21, be illustrated with the contrast between their mode of HHU management.Each application will be investigated respectively.For traditional user, set up the background data of relevant contest so that exist the triumph probability of allowing to comprise: read historical record of horses and the track in thenewspaper 508, watch the contest of that track or ontelevision set 510 tracks of horses interested, and onphone 512, convention is discussed.Be not converted into legacy user's information together with many life events of contest (test, training driving or the like).Available analysis is that newspaper proposes which what or legacy user put together.When the time of contest became closely a bit, obtaining further data unique channel was to forward special position (track or the color shop of fighting) to.Actual stake or transfer with the gambling money of having accepted bettor's account in person or by phone.The legacy user finds out the result that he bets by watching contest, makes a telephone call to and gambles the dealer or read second day newspaper.

Current user has the other resource that can use him.If current user treats that atcomputer 506 places they can be up to competition time by the data of ISP's 502 visits about contest and horses.Online fight color need an account and fail safe strick precaution are available still.Utilization is at a high data rate that the docking station place is available, and the stream video can provide exercise operation and contest itself but be current available.Computer also allow current customer analysis can with data in case find the trend and advantage.Current user's defective is this fact that need treat before computer.Therefore need the move around work of finishing them of many people can't be that their hobby uses land-line to connect computer equipment.

All advantages that HHU user has current user have the needed movement of commercial situation simultaneously.In addition, the present invention takes into account the mechanism of the contest of remaining valid.They want to receive any information user's preliminary election.But when the fresh information time spent in those classifications, the user is alarmed and information optionally is written into and is used for preparing visit among the HHU.The validity permission mobile subscriber of stream video watches the practice operation on contest and the HHU.When competition time was asymptotic, the user received the current data of relevant fight color model, stratagem ensuring success and track situation.

For this transaction application, the legacy user obtains main stock information by paper spare newspaper, analysis channel and company's file.The legacy user keeps up-to-date information by television set report, reservation and agency's service or telephone talk.Information quality suffers the time lag between special transaction group and non-special businessman's separation, and suffers such fact: promptly, analyze concerning most people and produced or provide analysis slow.Actual transaction is by phone or activates performance by a keyboard and put.Be confirmed to be by mail call or that in several days, transmit.

Current user utilizes the computer of connection to expand each activity of traditional businessman.Serial story, company's document and analysis are listed by online from the agency's introduction that is not only the businessman agency by online access.Action in one minute one minute of share price also is available.Online transaction provides the affirmation immediately of instant visit and transaction.

PDA user has the advantage identical with current user and the movement sexual clorminance and the feature of the present invention of increase.User's self defining programm is available easily.And the user is alarmed when events of interest takes place.

For these two application, the present invention owing to the individual procedure of verification of accelerating provide improvement response time, provide the improvement visit of data and action possibility and even advanced security when being used in the face of radio communication.

Described the preferred embodiments of the present invention, it will be apparent to those skilled in the art that now other embodiment that merged these notions also can be used.Therefore, the present invention is considered to not limited by described embodiment but only should be limited by the spirit and scope of accessory claim.
