Embodiment

Current, be to adopt text menu formula structure based on the WVAS of smart card, its interface is simple, dull, and is not strong to user's attraction, and this is that limitation owing to conventional smart card causes.The disposal ability of conventional smart card, interface rate and storage capacity are all very limited, can not do the computing of large amount of complex, can not transmit lot of data, can not preserve lot of data.At this situation, at present, a kind of novel smart card has appearred, and its computing capability, interface rate, memory capacity all have increased significantly with respect to traditional smart card, can use it to do complicated calculations, high-speed transfer and big capacity storage.The present invention is based upon on the basis of the powerful hardware platform that such novel smart card provides.

Realization smart card value-added service graphical interfaces and multimedia display are meant with graphical window and multimedia icon represents value-added service, to substitute traditional text type menu, shown in Figure 1A, 1B, Figure 1A represents traditional smart card value-added service explicit way, every menu item is a literal, and the part mobile phone terminal is supported in the menu text front and has small icon; Figure 1B represents display interface of the present invention, its icon is the multimedia form, except can being the graph image, can also be animation, video, and can change according to selection/operation of user, after selecting a certain menu or icon as the user, its icon can dynamically be adjusted and conversion, can also be equipped with the information of sound/music etc. and so on.

Because the resources such as inlet menu of WVAS are preset in the smart card, and the demonstration of its result or content and broadcast are realized by mobile phone terminal, therefore, consider that the Operational Visit resource needed is distributed in different places, realize the graphical and multimedization function of smart card value-added service, can adopt layer architecture, with mobile phone terminal as server end, specific implementation and finish multimedia display and playing function; And smart card sends multimedia operations request/order as client, thereby forms a kind of server/customer end, perhaps the server/browser framework.

Realize said structure and function, mobile phone terminal and smart card all need to support graphical display and multi-media player function.At present, most of mobile phone terminals have all had graphical display and multi-media player function, and still, smart card does not but have function corresponding, therefore graphical display and multi-media player function need be increased in the software architecture of conventional smart card, promptly shown in Fig. 2 A, 2B.Fig. 2 A represents the software configuration schematic diagram of conventional smart card, Fig. 2 B represents the software configuration schematic diagram of smart card of the present invention, relative traditional structure, the present invention increases graphical display function (Graphical User Interface, GUI) and the multimedia operations function (Multimedia Program Interface, MPI).

Except the software function to smart card strengthens, also need the interface and the agreement thereof of smart card are improved.The interface rate of conventional smart card is slow, does not support Connection-oriented Protocol, therefore, must make improvements, to realize Connection-oriented Protocol.This can realize by increase articulamentum between bottom physical transfer and upper layer application, as shown in Figure 3.Articulamentum is mainly realized the package (packet) of data and unpack (un-packet), and the data packet that is about to the upper strata becomes smart card transmission protocol data bag; Simultaneously, will recombinate, be reduced into the needed packet of upper layer application by the data that mobile phone terminal passes.

The bottom physical transfer interface protocol of smart card both can adopt traditional ISO/IEC 7816 agreements, also can adopt the high-speed interface agreement, as USB, SD/MMC etc.On this basis, for convenience and the unification that realizes, the function of articulamentum is to realize the TCP/UDP transmission according to the ICP/IP protocol standard.Except on smart card, increasing the function corresponding, on mobile phone terminal, also need to increase corresponding support function.Between mobile phone terminal and the smart card new communications protocol as shown in Figure 3, solid line is represented physical connection among the figure, the dotted line presentation logic connects.Like this, mobile phone terminal and smart card just can communicate according to ICP/IP protocol, just can realize more function and used on smart card.

The GUI module mainly realizes the graphical window function, is similar to Windows, XWindows/UNIX.The present invention mainly is with reference to existing embedded window system, as MiniGUI, Nano-X Window, Qt/Embedded, carries out transplanting development.

GUI comprises Drawing Object, as: the user interface of window, icon, menu and text, its structure is formed as shown in Figure 8.Select or activate these objects in some way, cause usually the action or change.Modal Activiation method is the motion of removing to control the mouse pointer on the screen with touch-screen, keyboard, mouse or other pointing device.Press mouse button, indicate selection or other action of object.

Window is mutual base area, mainly comprises title bar, menu bar, toolbar/operating space and viewing area.Icon is the logotype that is used to indicate an object, makes a title or function that operation more intuitively can be arranged.Menu is the action command of selecting for the user.In a software, all user commands all should be included in the menu.Menu will show that usually common type has toolbar (comprising the graphical tool hurdle), pull-down, Pop-up (right-click menu) and tandem type (multi-level menu) by window.Pointer is a figure, carries out visual description in order to the position that pointing apparatus (mouse, trace ball, directionkeys, navigation bar, lever etc.) is input to system.The systematic arrow that the pointer of graphical interfaces is commonly used, cross, text input I, wait hourglass etc.

The embedded type GUI function library is carried out the input-output equipment of embedded system abstract, as shown in Figure 9, it is divided into two kind equipment layers: based on the graph layer of graphic display device (as display screen), based on the input layer of input equipment (as keyboard, touch-screen etc.).Graph layer is finished the operation of system to concrete viewing hardware equipment, and the technology of hidden various different hardware realizes details largely, for the program development personnel provide unified graphical programming interface.Input layer then needs to realize the control operation for all kinds of different input equipments, and unified calling interface is provided.The embedded type GUI function library not only realizes drawing function, also is equipped with necessary function in the embedded type GUI designs such as keyboard/touchscreen events processing, dialog box, window system.Be applied to comparative maturity in the embedded Linux system at present, the GUI system bottom that function is also more powerful supports that there are SVGA lib, LibGGI, Xwindow, framebuffer etc. in the storehouse.

Qt/Embedded is an application framework and a window system that graphic user interface is provided for mini-plant specially.Abundant widget (Widgets) is provided, and the customization of support window parts, so it can provide beautiful graphical interfaces for the user.Qt is that the GUI that project such as KDE is used supports the storehouse, so there are many X Window programs based on Qt to be transplanted to easily on the Qt/Embedded version.The present invention selects for use Qt/Embedded as transplanting object.

The bottom graphics engine of Qt/Embedded is based on framebuffer, and framebuffer appears at the central a kind of UDI of version of the above kernel of Linux 2.2.x.This interface adopts the mmap system call, with display device abstract be frame buffer zone.The user can regard it as a map of display memory, and it is mapped to after the process address space, just can directly carry out read-write operation, and write operation can be reflected on the screen immediately.The framebuffer driver is one of most important driver, and this driver just can make the system screen displaying contents just.Its realization is divided into two aspects: the one, to the initialization of LCD and associated components thereof, comprise the establishment of picture buffer and to the setting of DMA passage; The 2nd, to the read-write of picture buffer, be system call interfaces such as read, write specific to code.

Therefore the bottom graphics engine of the Qt/Embedded framebuffer that places one's entire reliance upon need consider the realization situation of the linux kernel version and the framebuffer driver of target platform when transplanting, comprise the information of resolution and color depth etc.The most inner integrated LCD controller of current embedded type CPU, and support the various configurations mode.Can going wrong when hanging down color scheme except that minority CPU, Qt/Embedded can make up the graphics engine on upper strata preferably according to the existing framebuffer driving interface of system.

Graphic plotting handling function in the Qt/Embedded figure generation engine all is to initiate statement by defined QgfxRasterBase class among the src/kernel/qgfxreaster_qws.cpp among the source sign indicating number catalogue src/kernel/.For the equipment abstractdesription of bottom more, then give corresponding definition in the Qscreen class among the qgfx_qws.cpp in the src/kernel catalogue.These are the bases to framebuffer equipment direct control, comprise all definition realizations therein of functions such as point, line, zone filling, alpha mixing, screen drawing.After the debugging of framebuffer driver is passed through, dispose the compile option of Qt/Embedded, can guarantee the graphics engine operate as normal of Qt/Embedded.

Input equipment among the Qt/Embedded is divided into mouse class and keyboard type equally.Wherein realize among the src/kernel/qwsmouse_qws.cpp of mouse device in the source code catalogue, derive the realization class of some special mouse kind equipments again from such.According to the interface that concrete hardware drive program is realized, can realize similar interface function.

Actual function for keyboard response among the Qt/Embedded is arranged in src/kernel/qkeyboard_qws.cpp, in qkeyboard_qws.h, has defined the base class QWSKeyboardHandler of keyboard type equipment interface.Concrete keyboard hardware interface still will be based upon on the keyboard driver basis, need derive the realization class from such according to keyboard driver during transplanting, realizes that KeyEvent processing function processKeyEvent gets final product.

The UNICODE coding standard has been adopted for the processing of character set in Qt/Embedded inside.The UNICODE coding standard has been adopted for the processing of character set in Qt/Embedded inside.Qt/Embedded supports two kinds of support patterns for other coding standard (as GB2312 and GBK) simultaneously: static compiling and kinematic insert are loaded.Add respective coding by configuration config.h file and support macrodefinition, can obtain of the conversion support of other coding standard, thereby in the Qfont class, changed and demonstration to UNICODE.Because UNICODE has been contained Chinese part, Qt/Embedded is also very good to the Chinese support.

Qt/Embedded can support TTF, PFA/PFB, BDF and QPF font format.Owing to self adopt the UNICODE coded system that character is handled, on certain program, caused the increase of the font file volume that can use.In order to address this problem, Qt/Embedded has adopted the QPF form, and instruments such as use makeqpf can be converted to the font of forms such as TTF the QPF form.

The same with the GUI module, the MPI module is mobile media API (the Mobile Media API with reference to the standard among the J2ME, MMAPI) it is carried out transplanting development, make it provide one to overlap the broadcast of standard and record audio frequency and the interface of video, realize operating functions such as multimedia demonstration, broadcast, for example audio plays and video file, catch sound and image etc., also using for mobile multimedia and develop simultaneously provides a standard, standard, general, extendible and simple interface.In J2ME, class that MMAPI provides and interface are all in javax.microedition.media.

Usually two important links are arranged in multimedia processing procedure, the one, the agreement of deal with data transmission, another is a data type of handling medium.In MMAPI, provide data source (Data Source, DS) and player (Player) finish this important content of two steps.

The process of handling host-host protocol sends it to the process that media data content is handled (player) after being meant and reading media data content from data source (as a file, an acquisition equipment or a stream service).The process that MMAPI uses DS to come the host-host protocol of processing media data.DS encapsulates Data Transport Protocol, no matter it is come wherefrom, can be stream, file or server resource or the like.A DS knows how to read media data from its home position and send media data processing (as player) to.Media data can be stored in different positions, from the remote server to the resource file or RMS (Record Management System, record management system) database.Media data can pass through HTTP from the home position, as the stream transmission agreement of RTP, perhaps other mechanism are transferred to media data and handle (as player).Figure 10 has showed the course of work of data source.

The process of processing media data content need make an explanation and decode usually media data, and needs the type of the output setting of these medium of identification, audio setting or video setting in this way.Give an example, when data source is obtained a MP3 media data from certain media data source, and send it to processing media data content process, this process is at first resolved this MP3 media data and is decoded, detecting these MP3 medium simultaneously is voice data, the audio frequency apparatus of device for opening directly is sent to parsing and decoded media data in the audio frequency apparatus buffering of device, produces audio signal by this audio frequency apparatus according to the data content in the buffering area.

MMAPI uses player (Player) to come the processing media data content.Player then is responsible for decoding work, and is transferred to peripheral hardware, as display screen and loud speaker.

Player reads media data, parsing and decoded data and identification medium output equipment and media data to output equipment etc. from data source.Player provides methodology to go to control the playback of medium with synchronously.

MMAPI also provides one or various control device (Controls) to adjust the behavior of player, can obtain and use controller from a player example in the media conversion data at player.Can be by some the special medium types of some special controller access that provide in the player.

In order to realize effective management to data source and player, use factory's mechanism, be responsible for creating player and data source by keeper (Manager).The entrance of MMAPI is keeper (Manager) class.The keeper not only can create player from data source, but also can create player from this locality or inlet flow (Input Stream).Figure 11 has showed MMAPI overall structure figure.

Simultaneously, in order to guarantee the transmission of figure and multi-medium data, must improve the communication protocol of smart card, with reliable transmission and the unified control that guarantees data, this can realize by increase Connection-oriented Protocol on the basis of the bottom host-host protocol of smart card, as ICP/IP protocol.The bottom physical transmission protocols of smart card both can be traditional ISO/IEC 7816 agreements, also can be the high-speed interface agreement, as USB, SD/MMC etc.Equally, on mobile phone terminal, also need to support corresponding protocol, like this, between mobile phone terminal and smart card, just can set up TCP/IP and be connected, as shown in Figure 6, on this basis, just can realize more, more complicated function and application.

TCP/IP (transmission control protocol/IP(Internet Protocol)) is a kind of network communication protocol, its standard all communication equipments on the network, the especially data between a main frame and another main frame contacts form and load mode.ICP/IP protocol is commonly referred to TCP/IP protocol suite.With it serves as that the INTERNET that the basis is set up is present largest in the world computer network, just because of being extensive use of of INTERNET makes TCP/IP become de facto standards.Why say that TCP/IP is a protocol suite, be because ICP/IP protocol comprises TCP (Transport Control Protocol, transmission control protocol), IP (Internetworking Protocol, the inter-network agreement), UDP (User Datagram Protocol, User Datagram Protoco (UDP)), ICMP (Internet Control Message Protocol, ICMP), RIP (Routing information Protocol, routing information protocol), FTP (FileTransfer Protocol, file transfer protocol (FTP)), SMTP (Simple Mail Transfer Protocol, Simple Mail Transfer protocol), SNMP (Simple Network manage Protocol, Simple Network Management Protocol), ARP (Address Resolation Protocol, address resolution protocol) many agreements such as, these agreements are called ICP/IP protocol together.

TCP/IP provides a scheme to belong to same in-house network and how to adhere between two computers of different physics nets the problem of swap data separately with solving.This scheme comprises mass part, certain part that each member of ICP/IP protocol collection then is used for dealing with problems.Concentrate basic protocol-IP agreement to be used in in-house network swap data and carry out an important function as ICP/IP protocol: Route Selection--select datagram from the A main frame to path that the B main frame will pass through and utilize suitable router to finish leap (hop) the heterogeneous networks.

ICP/IP protocol is observed one four layers model concept: application layer, transport layer, interconnection layer and network interface layer.As shown in figure 12.

The ■ network interface layer: be responsible for the transmission and the reception of Frame, frame is network information transfer unit independently.Network interface layer is placed on frame on the net, or from network frame is taken off.

The ■ interconnection layer: interconnection protocol is dressed up the internet datagram with data envelope, and the necessary routing algorithm of operation.Four interconnection protocols are arranged:

◆ Internet protocol IP: be responsible for addressing and route data packets between main frame and network.

◆ ARP: obtain the hardware host address in the same physical network.

◆ internet control messages agreement ICMP: send message, and the transmission mistake of report relevant data bag.

◆ interconnected igmpinternet IGMP: brought to local multiplex broadcasting router report host groups member by the IP main frame.

The ■ transport layer: host-host protocol provides communication session between computer.The selection of host-host protocol is decided according to data transfer mode.Two host-host protocols:

◆ transmission control protocol TCP: communicate to connect for application program provides reliably.Be suitable for once transmitting the situation of bulk data.And be applicable to and require the application program meet with a response.

◆ User Datagram Protoco (UDP) UDP: connectionless communication is provided, and has not guaranteed reliably to transmitting bag.Be suitable for once transmitting small amount of data, reliability then is responsible for by application layer.

The ■ application layer: application program is by this one deck accesses network.

The BTU of ICP/IP protocol is datagram (datagram).Transmission Control Protocol is responsible for data are divided into several packets, and add packet header (just as adding envelope for an envelope letter) for each packet, corresponding numbers is arranged on the packet header, to guarantee that at data receiver can be original form with reduction of data, the IP agreement is added the receiving terminal host address on each packet header, data find the place (just as writing the address exactly on the envelope) that oneself will go like this, if occur situations such as loss of data, data distortion in the transmission course, Transmission Control Protocol can require data to transmit again automatically, and group is wrapped again.In a word, the IP agreement guarantees the transmission of data, and Transmission Control Protocol guarantees the quality of transfer of data.

In the present invention, mainly realize IP, TCP, three kinds of agreements of UDP, the assurance smart card both can be communicated by letter with mobile phone terminal, also can communicate by letter with the webserver, provided the uniform communication interface for various application again simultaneously.

IP realizes two basic functions: addressing and segmentation.IP can be sent to destination address with datagram according to the destination address that comprises in the packet header, and IP is responsible for selecting the road that transmits in this process, and this selection road is called routing function.If can only transmit the small data newspaper in some network, IP can re-assembly packet and indicate in header field.

The IP layer receives the packet of being sent by low layer (network interface layer, for example ethernet device driver) more, and sends to this packet more high-rise---TCP or UDP layer; On the contrary, the IP layer is also being sent to more low layer from TCP or the next packet of UDP layer reception.The IP packet is insecure because IP do not do anything confirm packet be send in order or do not have destroyed.Contain the address (source address) of the main frame that sends it and the address (destination address) of its main frame of reception in the IP packet.Its form (is example with IPv4) is as shown in figure 13:

■ version (version): 4 bit fields, the version of IP agreement is described, allow to become another version from a protocol version.

■ header length (length): 32 word lengths, the length of description packets headers.

■ COS (Type of service:TOS): 8 bit fields are used to distribute priority, delay, throughput and reliability.Be used for required COS or " quality " of designation data newspaper.

■ total length (Total length): the total length of datagram is described, maximum length is 65,536 bytes.

■ differentiates (Identification): provide the information that connects independent segmented datagram, so the purpose website just can be assembled into them a complete grouping.

■ indicates (flags): be made of 3 bit fields, wherein low two (least important) control burst.

Low level points out whether packet can carry out burst.Interposition points out whether packet is last burst in a series of packet segments.The 3rd is that highest order is not used.

■ field offset amount (Fragment offset): 13 bit fields, for the segment data newspaper, the origin-location of these data in grouping pointed out in this territory, will use this information in the process that re-assemblies.

■ life span (Time-to-live): with the second is unit, and it is the time that datagram can be survived.

In transmission, if surpassed this time, this datagram just is considered to lose, or in a circulation and go out of use.

■ agreement (protocol): the protocol type of identification data newspaper so just can allow non-ICP/IP protocol work.

The check of ■ packets headers and (header checksum): provide an error checking numerical value, to guarantee an integrality that is distributed grouping.

■ source/order address: this is the address of datagram seedbed and this datagram destination.

■ option (option): this territory is optionally, it provide record by network a paths or specify a paths (seedbed Route Selection).

■ fills (Padding): elongated, be used to guarantee that header is 32 a multiple.The filling value is 0.

■ data: comprise upper layer information.

TCP is the transport layer protocol in the ICP/IP protocol stack, and it is confirmed by sequence and the bag retransmission mechanism, provides reliable data flow to send and arrive the virtual Connection Service of application program, allows to operate in the mutual switched traffic of application program on different main frames.TCP is divided into segment with data flow and is called tcp data section (TCPsegments), and utilizes the IP agreement to transmit.In most of the cases, each tcp data section is contained in the IP datagram and sends.But if required, TCP will be divided into a plurality of datagrams to data segment, and the physical data frame of transmission bit stream and byte stream is compatible between then different with the consolidated network main frames of IP datagram.Because I P can not guarantee that the order of the datagram that receives is consistent, TCP can collect mail end assembling tcp data section and form a continual data flow.FTP and Telnet are exactly the TCP/IP application program of two popular dependence TCP.

Because most of web applications all move, must be able to guarantee on the computer that the software program on the machine of destination can obtain packet from the source address machine, and source computer can be received correct answer on same machine.This finishes by using TCP " port numbers ".Network ip address and port numbers are combined into unique sign, are referred to as " socket " or " end points ".TCP connects between end points or virtual circuit carries out reliable communication.

The Transmission Control Protocol structure is as shown in figure 14:

Source Port identification upper strata source processor receives the point of TCP service.

Destination Port identification upper strata target processor receives the point of TCP service.

Sequence Number specifies the sequence number that is assigned to the data first byte in the current information usually.

Connecting establishment stage, this field is used for setting the initial sequence number of transmission.

Acknowledgment Number comprises the sequence number of next byte of data of packet transmitting terminal expectation reception.In case successful connection, this value can be sent out always.

4 of Data Offset.32 word sequence numbers in the Transmission Control Protocol head are represented the data starting position.

6 of Reserved.Reservation must be set to 0 with standby.

6 of Control Bits (Flags).Transmit various control informations.Control bit can be:

16 of Window.Specify the size of transmitting terminal receive window, that is to say eight buffer size that data can be used.

16 of Checksum.Point out whether protocol header is destroyed in transmission.

16 of Urgent Pointer.Point to first significant data byte in the packet.

Option+Padding specifies various tcp options.Option has two kinds of possibility forms: single eight optional types and eight optional types, eight hytes of eight selectable length and actual optional data.

Data comprises upper layer information.

Tcp data is encapsulated in the IP datagram as shown in figure 15.

Another important agreement is User Datagram Protoco (UDP) (UDP).UDP is a kind of connectionless transport layer protocol, and the simple unreliable information transfer service towards affairs is provided.Udp protocol is the interface of IP agreement and upper-layer protocol basically.Udp protocol adopts " port numbers " to differentiate a plurality of application programs that operate on same the equipment.The same with TCP, UDP is a transport layer protocol, serves a lot of well-known application layer protocols, comprises NFS (NFS), Simple Network Management Protocol (SNMP), domain name system (DNS) and simple files transmission system (TFTP).

The udp protocol structure as shown in figure 16.

Source Port-16 position.Source port is an Optional Field.When using, the port of its expression router, it also is considered to not have to need under the situation of out of Memory the answer port that is addressed simultaneously.If do not use, the value of setting is 0.

Destination Port-16 position.Target port has meaning under the situation of special internet destination address.

The Length-16 position.Eight bit lengths of this user datagram comprise protocol header and data.The length minimum value is 8.

The Checksum-16 position.IP protocol header, udp header and data bit are at last with the false protocol header summation of 0 information of filling up.If necessary, can be composited by two eight.

Data-comprises upper layer data information.

The difference of TCP, udp protocol is as shown in the table:

	TCP	UDP
	TCP	UDP	Whether connect	Towards connection	Towards disconnected
Transmission reliability	Reliably	Insecure	Whether connect	Towards connection	Towards disconnected
Transmission reliability	Reliably	Insecure	The application scenario	The transmission lot of data	Low volume data

In like manner, also can realize ICP/IP protocol on the basis of host-host protocols such as USB/SD/MMC.

Along with development of internet technology, surfing Internet with cell phone has become a kind of trend, and a large amount of mobile phone terminals all has been equipped with web browser, and the wireless Internet value-added service obtains great development.But because the opening of the Internet and the diversity of value-added service cause value-added service very different, some harmful contents have had a strong impact on the normal development of wireless internet service, therefore, must strengthen monitoring and management to the wireless Internet value-added service.Since operator to the influence power of mobile phone terminal production firm a little less than, therefore, operator wants to realize monitoring and the management to the wireless Internet value-added service, must realize by smart card, this just requires smart card must realize the function of network browsing, promptly need be embedded in Internet-browser at smart card.

Will be embedded in Internet-browser at smart card, at first must support ICP/IP protocol, this can adopt preceding method of the present invention to realize.But because the open requirement of the Internet, the browser in the mobile phone terminal also is wide-open at present, and promptly browser can be linked into arbitrarily that internet content gets on.And operator is in order to realize the control to the Internet value-added service and content thereof, just must the business that the browser in the smart card can insert be limited, only allow it to be linked into legal value-added service, be that the smart card browser must be the access of restricted property and browse, can only realize opening to a certain extent, so just can accomplish monitoring value-added service.

Realize limited access and the supervision of smart card, can adopt the method for segmentation storage, segmentation visit the wireless Internet value-added service.At first the structure and the content of value-added service are carried out segment processing, be divided into access path and business tine two parts; Then, basic structure is constant or change seldom access path as the part of application program of intelligent card, in smart card production distribution, just be solidificated in the smart card in advance.This part content both can be used as an independently application program existence, visited by the browser in the mobile phone terminal, also can bind together with the smart card browser, as its collection file; And will need the business tine of real-time update or often variation still to be kept on the webserver, and like this, the corresponding network architecture and following Fig. 4 of browsing process and shown in Figure 5 thereof.

At last, when the user passes through the value-added service of smart card (or mobile phone terminal) access internet through browsers, owing at first need smart card to carry out networking certification, therefore, after authentication success, automatically the ingress path of Operational Visit is forced to be directed to the business that presets in the smart card by browser, as among Fig. 4 1. 2. shown in, thereby realize control to service access.This process is repeatedly carried out alternately, visits the service path that all preset step by step, as among Fig. 5 1. shown in, thereby finish service access and navigation function; Be linked into again on the webserver after all service path/contents in having visited smart card, obtain final real time business content, as among Fig. 4 3.～6. shown in.Concrete Operational Visit flow process as shown in Figure 5.Because operator can be preset at smart card with relevant business tine in smart card production distribution (the individualized in advance or individualized) stage, therefore, by this method of the present invention, operator can control the increment contents that the user can insert or visit fully, thereby realizes the purpose of limited access and business monitoring.

Current, WVAS is of a great variety, for the ease of management and search, all adopts classified and layered way basically, according to the thought of " earlier big class, back group, subclass " again to its alignment placement.For ease of explanation, suppose to have a WVAS that is named as " online game ", its business structure and composition are as shown in Figure 6., only be used for exemplary illustration herein, do not represent real business.

This clear in structure is understood, search easily, but because layering many (being illustrated in figure 6 as six layers), cause the service menu or access links (the being referred to as service path) level of value-added service dark excessively, when the user visits value-added service at every turn, to final business tine, need a lot of steps of operation (being five steps shown in Fig. 6) just can find final content from ingress path (be first order menu, or ground floor linking).No matter this business is STK is used, or the WAP/Internet business, and the user must finish multi-pass operation (choice menus or browsing page) could obtain final business tine, causes Operational Visit efficient extremely low.In addition,, also strengthened the communication load of network, caused the wasting of resources for the WAP/Internet business.Trace it to its cause, this is that the Operational Visit level too much causes.When user capture is professional in fact, care be business tine, therefore rather than service path, should obtain business tine with the shortest service path.Because service path level and structure basic fixed are constant, therefore, the user there is no need (as shown in Figure 6 " Chinese chess ") necessary traversal its all service paths at different levels (as the first～Pyatyi menu among Fig. 6) when the same business of each visit fully.For this reason, the present invention proposes a kind of smart card value added service management and visit new method, with the operational access efficient of effective raising smart card value-added service.

Concrete grammar of the present invention and content are: ignore to begin what service path (as the first～level Four menu among Fig. 6) in the service path most, only keep the ingress path (as level V menu in Fig. 6) of the service path of afterbody, point to final business tine by it as necessity; Then, the ingress path (being referred to as " professional shortcut ") with all these reservations concentrates on unified management and use in the first order menu.Like this, when the user uses this new menu, only need two steps of operation just can obtain final business tine, thereby can avoid visiting step by step the inconvenience that brings.

The quick access mode of smart card value-added service mainly is to realize by the service path of smart card value-added service is effectively managed, and this can be by setting up a collection, the shortcut that is used to collect Operational Visit in the smart card browser.Its concrete mode as shown in Figure 6, a newly-built catalogue or window in collection, as " my business ", to need the afterbody service path (as the level V menu " Chinese chess " among the figure) of the business of fast access as its menu item, just its access path is saved in " my business " file of collection, newly-built menu item all points to same service path or content with the service path of original menu item, like this, only need visit this inlet menu when the user visits later on and get final product, thus the partial service path in the middle of can dispensing.Mechanism is similar to the shortcut of PC application program in fact, both can also can adopt embedded database to realize the dynamic menu management with the mode of chained list.New menu item just forms the quick access mode of this value-added service, is directed to final business tine by it.Like this, the user can generate shortcut with all value-added services of often using, and unified being kept in this new catalogue manages and use, thereby shortened access path greatly, improved Operational Visit speed and efficient.

Illustrate above-mentioned thought and its implementation below.As shown in Figure 7, suppose to have two class WVASs (both can be that STK uses, also can be the WAP/Internet Network): online game, Web education, they comprise multi-stage service branch (son) class and service path thereof respectively.

A newly-built first order menu " my business ", comprise " Chinese chess " and " Senior Three chemical experiment content " two kinds of business (son) types, its service path is respectively " Chinese chess ", (the Senior Three chemical experiment) " experiment content " in " Web education " in " online game ", as shown in phantom in FIG..When the user needs to use " Chinese chess " professional, only need " Chinese chess " under the visit " my business " to get final product, must not visit " online game " → " leisure " → " chess category " → " Chinese chess " → several service paths such as " Chinese chesses " successively the conventional method and could obtain business tine and do not need to resemble, thereby reduced operation link, improved access efficiency.

Consider the description of this invention disclosed herein and special embodiment, other embodiment of the present invention are conspicuous for the technical staff in this area.These explanations and embodiment only consider as an example that they all belong to by within the indicated protection scope of the present invention and spirit of claims.
