Other parameter of the user's of the concrete storage key of memory M2, identifier and transaction card configuration file, for example PIN(Personal Identification Number) sign indicating number and other secure data.With reference to the present invention, memory M2 specifically comprises remaining sum backup (balance backup) and uses specific application SES and the proprietary parameter PP of network.

Memory M3 belongs to RAM type or static RAM (SRAM) (SRAM) type, more specifically is used to handle the data that receive and transmit via the input/output end port PES related with card reader LT.

Call out consumption meter server S CC and comprise remaining sum (balance) manager GS and communication interface IC, and comprise or be connected to database BD.Server can be included in the user-management for customers device system that is used for supervising the network RR.Database specifically comprises customized parameter in advance, and the calling consumption that they have been subscribed to the operator of network RR with the user's of card identity, with the user of card is subscribed configuration file and with the sign of card CP, for example the user's of sequence number, the card of card the international mobile subscriber identifier (IMSI) and the type of blocking are relevant.

Specifically, with reference to the present invention, database BD comprises predetermined information, and it will send card to via terminal by server S C, so that use described information in subscriber equipment under the control of card.Predetermined information is specifically called out the remaining sum of consuming the account by prepayment and is constituted, perhaps the accumulating sum of having been consumed by the calling since nearest payment in a variation constitutes, and constitute by validity date of account and other text and/or image indication (image indication) alternatively, for example be used for making the Application Parametersization that smart card comprises and/or make the portable terminal parametrization.

Database BD comprises and calls out the consumption meter, they respectively with the smartcards of having paid in advance that the user had for the calling of being set up via radio circuit RR.For fear of making Fig. 1 confusion, the calling consumption meter CO relevant with smart card CP only is shown.In the following description, suppose that predetermined information comprises the value of the prepayment calling consumption account's who equates with counting of counter or meter CO remaining sum SD at least.Remaining sum increases progressively certain amount of money when the user of the smart card CP that at every turn authorizes coulometer pays in advance, and from the terminal of related smart card CP, successively decreased after for some incoming call (incoming call) and each call for any outbound call consumption except free outbound call (outgoing call) and emergency services outbound call as terminal TM.

Call meter or call out meter CO be called " attaching position register " (HLR), comprise relevant and database RR initial characteristic that when card being entered serve, be recorded immediately of type with the sign of smart card CP and card and communicate.Described initial characteristic specifically be user's IMSI, mobile subscriber's the telephone number of sequence number, card of card or " travelling carriage ISDN number " (MSISDN) and the type of card.The type of smart card CP specifically identifier, the figure place by handled each word of processor, the characteristic by the operating system of installing in the card and/or virtual machine of the identifier by the type of the processor that comprises in the card, the manufacturer by card waits and discerns.The use of card and other specific characteristic of specifically being used by the user who blocks also can be recorded in HLR when making card enter service, and can be modified between the operating period of card.Described other characteristic is specifically related to the user's of smart card CP reservation configuration file, in this example, its configuration file is to call out pay subscription in advance and can be by user or the data of being made amendment by the operator of control card, for example file of the telephone directory of telephone number and e-mail address and radio circuit identifier.

HLR or the database related with it also are included in and make smart card CP enter viability or be loaded before and/or described smart card enters the identifier of the application program that is downloaded after the service.

In the present invention, one of application identification symbol is specified the remaining sum backup, and specific application SES is used for reception and uses, specifically is used to show predetermined information, for example calls out consumption from prepayment and counts the remaining sum SD that reads the CO.Application program SES is installed among the memory M1 and/or M2 of smart card CP, and is used for coming the more remaining sum SD of new terminal TM according to scheduled event.Specific application SES among the smart card CP can be suitable for disposing radio circuit RR, specifically can be suitable for the application program that puts in place being set by the operator of network, and in this example, can be suitable for having the operation of the server S CC of database BD, be used for the All Files of the proprietary file of predetermined information of visited network operator thereby nonstandardized technique information, as remaining sum SD.Therefore, application program SES and radio circuit RR are irrelevant.In specific application SES, realize the formative standard auto-mechanism of the message that concrete relevant and server S CC, SV exchange, be used for initialization and use the proprietary of Virtual network operator thereby and nonstandardized technique information, as remaining sum SD, and be used to make described information to be shown alternatively in the mode of user transparent, and irrelevant with the type of the type of network RR and the portable terminal TM that admits smart card CP.

The exchange of management of balance device GS management and HLR is so that the function of the calling consumption of carrying out as user's payment in advance and user increases progressively and successively decreases and count CO.HLR transmits to meter CO and comprises calling out the designated call bill (named call ticket) of the required full detail of appraisal.Management of balance device GS also manage with smart card CP in the exchange of application program SES, be used for coming the more remaining sum SD of new terminal TM according to scheduled event.

Communication interface IC transmits and receives message, is specifically to be suitable for counting response and the request that the indirect between server S CC and the network RR networks, for example Internet Protocol (IP) grouping when the indirect networking is the internet.

The message that exchanges between portable terminal TM and calling consumption meter server S CC can be the SMS message of encryption or alternate manner according to routine.Under the sort of situation, server S CC for example is connected with short message service server via special-purpose (renting) link.

In another embodiment, the signaling channel by supplementary service data USSD (unstructured. supplementary service data (Unstructured Supplementary Service Data)) exchanges the message that exchanges between terminal TM and server S CC.For example, " sending USSD " proactive command that is transmitted to terminal TM by card CP makes it possible to exchange request and response by the message of this form.

In yet another embodiment, voice server SV is included in fixing (non-moving) part of network RR, and for example is connected with server S CC via leased line.In a variation, voice server SV is attached to server S CC with the form of the voice service application program that is used for calling out consumption.The voice request message that is used for request call consumption remaining sum that portable terminal sends is transmitted to SCC by voice server SV.Sound identification module among the voice server SV becomes the voice request message conversion by the explainable request message of server S CC, receive the data request information that directly transmits by terminal as described server S CC, so that consumption is called out in monitoring/tracking, and is as mentioned below.Card CP is Interactive Voice Response (IVR) request of voice server SV via terminal T and via the voice request message that voice server SV transmits to server S CC.

With reference to Fig. 2, use the method for the present invention of information to comprise that step e 1 is to E9.

At initial step E1, portable terminal is in standby, and supposition card CP comprises that remaining sum backup and use are at factory or the later specific application SES that loads.The proprietary parameter PP of network of the operator of network RR is stored among the memory M2, makes the content that application program SES visits predetermined information, calls out consumption meter CO as prepayment via the server S CC of operator's management of network RR.Proprietary parameter PP for example comprises: the address of server S CC; The input and output port of management of balance device GS; Calling channel; The request message format of inquiry manager GS, for example SMS message, USSD message or speech message; The form of the proprietary file of predetermined information is used for the language of videotex information comprising text, Virtual network operator in the response message such as SMS message or USSD message for example; And the operator of network RR is used for the reference units to remaining sum value, for example monetary unit.Remaining sum SD is as predetermined information, and its value is the value that is updated after detecting nearest incident, and its incident defines hereinafter, and it is shown on the display of mobile terminal user interface IU usually continuously.

In a variation, for example the smart card in portable terminal TM is first with network RR when attached, and the Download Server of the operator of radio circuit RR is downloaded the proprietary parameter PP of network of the application program SES among the smart card CP via normative document, via terminal TM.Then, application program SES will pass to terminal as the suitable parameter of the function of proprietary parameter, make terminal specifically be suitable for receiving to comprise predetermined information, as the message of remaining sum, they is transmitted to application program SES, and use predetermined information.Terminal TM is used to the network Proprietary Information to discern and is not to be sent to smart card CP and to comprise the message of remaining sum SD with standard mode.Then, these message are passed to application program SES in the smart card, so that analyze remaining sum.Download Server also is used for the function that operator according to network RR wishes the change carried out in certain information of use and revises parameter and message structure.

Event checking module DEV among the application program SES notes monitoring any scheduled event EV.Event checking module can take to be called among the smart card CP form of the application program part of " cardlet " (card applet (card applet)), and the Another application program part that is called " midlet " (mobile information apparatus applet (Mobile Information Device applet)) among this part and the terminal TM again is related.In step e 2, event checking module DEV detects the specified scheduled event EV of correspondence order that transmits by portable terminal TM, and " waking up " application program SES.In a preferred exemplary, scheduled event EV is the outbound call request that takes place after the user acts on the handoff functionality key of terminal TM.The session of SIM application toolkit (SAT) type is opened in call request, during this period, uses SIM application tool packet interleaving asynchronous communications protocol, transmits order by portable terminal TM to smart card CP, and transmits response by smart card CP to portable terminal TM.

Then, SIM or the USIM application program of card among the CP begins to set up with the signaling of the standing part of network RR and is connected, make the terminal that the user asked of the communication interface ICT calling terminal TM in the terminal or any other entity, as server.During the foundation of outbound call, in step e 3, application program SES decides to terminal TE via SIM or USIM application program and transmits the proactive command that comprises balance request RS.This request is formatd by the function of smart card according to proprietary parameter PP, is transmitted to terminal TE then, is transmitted to the request message MRS that calls out consumption meter server S CC so that send.For example, proactive command belongs to " sending SMS message " request type.Balance request belongs to the inquiry type, and specifically comprise the temporarily moved subscriber identification (TMSI) of card CP, the address of meter server S CC, the input and output port of management of balance device GS and the code that indicates the service of asking, it is a balance request in this example.

In server S CC, in step e 4, balance request RS is extracted from message MRS by communication interface IC, and is handled by manager GS, so that identifier IMSI and balance request code from wherein reading card CP.The identifier of card CP sends HLR to by manager GS, and HLR provides the calling among the database BD to consume the address of counting CO to GS after inspection user equipment TM-CP and network RR are attached.

In step e 5, the related remaining sum SD of user of meter remaining and smart card CP that address that provide with HLR is specified among the CO is provided manager GS, and will insert the response message MSD that send subscriber equipment TM-CP to as the remaining sum that form read of proprietary file FP.Also can adopt side information, as account's validity date and specifically be that the content that (promotional insert) replenishes response message MSD is inserted in sales promotion.The information that comprises among the response message MSD can belong to text type or multimedia type (text, sound and image).

Have predetermined length with the data field among the proprietary file FP corresponding response message MSD, and for example comprise five field CH1 to CH5 of form shown in Figure 3.The field CH1 that data field begins to locate comprises to be shown as the text of customized parameter and information in advance, and has minimum length L1m.Field CH2 comprises and equals to read the CO and call out the binary numeral of the mixed decimal point of consumption remaining sum SD with the prepayment of smartcards from meter.The length L 2 of field CH2 changes according to the function of the standard that Virtual network operator determined, and less than maximum length L2M.Field CH3 comprises the character of the reference currencies unit that specifies country, and it is used for remaining sum is evaluated by the operator of network RR.Field CH4 comprises and validity date smartcards and that show in day, Month And Year, and wherein Shuo Zi order and quantity are variable and are selected by the operator of network RR.Therefore, the length L 4 of field CH4 is variable, and less than maximum length L4M.The field CH5 of data field ending comprises to be shown so that present the word of remaining sum, for example " your remaining sum is (remaining sum, a monetary unit), and be (validity date) validity date ".The variable-length of field is the proprietary parameter of network RR.

In terminal TM, network interface IR is applied to communication interface ICT with response message MSD, it relies on by previous recognized to the terminal transmission or by the terminal configuration parameter that terminal reads that response message comprised remaining sum by smart card from smart card, and response message is transformed into the order that sends smart card to.In step e 6, application program SES storage proprietary file FP, and handle received information, promptly consume remaining sum SD and any side information is so that be transformed into normative document FS with it and described normative document be kept among the memory M2 of smart card CP.The predetermined information that is received in the storage standards file is convenient to read described information by main SIM in the smart card or USIM application program, so that at next procedure E7 described information is passed to portable terminal TM.

In a safer realization, in step e 6, application program SES also make the parameter that comprises configurating terminal and consumption remaining sum SD the predetermined information that receives in the particular memory space ES of memory M2, back up (preservation).Form by the proprietary file FD that transmits as management of balance device GS and received via portable terminal TM by smart card CP backs up received information, and need not to be transformed into normative document FS by application program SES.The backup proprietary file FP that comprises the predetermined information that receives can't directly revise by the order from portable terminal, because proprietary file is the portable terminal inaccessible.Therefore, accidental when using as predetermined information that normative document received, it is deleted or rewrite to prevent to back up proprietary file physically.

If admitting the portable terminal TM of smart card CP is " standard " card, then application program SES does not use the backup proprietary file.

On the contrary, if smart card CP is related with specific portable terminal, then application program SES thinks the special properties of portable terminal the function of the characteristic of the portable terminal that obtained by smart card when related with portable terminal.Under the sort of situation, by reading backup proprietary file FP, and it is transformed into normative document when making the normative document of information be delivered to the memory of portable terminal whenever communication interface ICT, upgrade the normative document FS of predetermined information.The deletion unintentionally of the normative document of predetermined information or not influence of rewriting are because predetermined information still backs up in particular memory space ES with the form of proprietary file FP.

In step e 6, the function of proprietary parameter PP of being obtained according to smart card CP of network and the characteristic of portable terminal TM, handle its form by consumption remaining sum SD and any side information among the file FP of operator's implementation of network RR, so that make them be particularly suitable for the form characteristic of the display of user interface IU.The formative by this way received information that comprises remaining sum by SIM or USIM application program be included in standard SIM kit proactive command, as in " setting up idle pulley text (SETUP IDLE MODE TEXT) ", it is transmitted to portable terminal TM in step e 7.

Communication interface ICT in the terminal applies the formatted message that extracts to user interface IU from proactive command.In step e 8, display shows this information continuously, replaces corresponding old information.Therefore, the user receives about remaining consumption remaining sum SD when outbound call begins.Remaining sum SD continue to show in whole calling, till the renewal next time that can occur during calling out or when finishing.

If application program SES detects in step e 5 and sends mistake in the order of smart card to, perhaps can't find remaining sum in the data field of described order in step e 6, then this method is returned step e 2 or E3, and displayed information remains unchanged.

After show confirming that order AC has sent smart card to by terminal, in step e 9, remaining sum backup and user-specific application SES turn to standby, as it in step e 2.Then, event checking module DEV notes monitoring specified another scheduled event EV of communications of Mobile Terminals interface ICT.

In first realizes, manager GS itself decision (push mode) during setting up outbound call, preferably regularly, consume remaining sum SDA as approximately transmitting updating call, shown in the dotted line in the step e 5 every ten seconds.More new balance SDA is read the CO from meter, and preferably regularly by server S CC take new balance message MSDA more form, the out of Memory in proprietary file FP transmits alternatively.After having transmitted more new balance message MSDA in this way, method then forwards step e 6 to from step e 9.Event checking module DEV among the smart card CP detects and comprises the balance updates request command that produces among the message MSDA of proprietary file FP and the communication interface ICT conversion from portable terminal TM.In card, the proprietary file FP with any other side information that comprises among new balance SDA more and the message MSDA is upgraded in application program SES storage and handling, in step e 6.Operating procedure E7 and E8 once more, be transformed into renewal normative document FS so that will upgrade proprietary file FP, upgrade predetermined information so that from upgrade normative document, extract, described renewal predetermined information is inserted proactive command, and the concrete display update remaining sum of the display SDA that passes through portable terminal.Then, the user knows the residue remaining sum SDA of renewal during whole outbound call, and can determine better once more to the time of deposit account (credit) and the time of terminated call.

If in step e 9, event checking module DEV detects the specified on-hook of disconnection connection request order that portable terminal TM transmits, then this method is returned step e 2, makes application program SES transmit to portable terminal TM via SIM or USIM application program and comprises the proactive command of upgrading the proprietary file request.Operating procedure E3 to E9 once more: manager GS reads remaining remaining sum SD among the meter CO when end of calling; The response message MSD that terminal TM will comprise the renewal proprietary file with the more new balance that reads is transformed into order; And the application program SES in the smart card initiates to have the format proactive command of new balance more that passes to portable terminal, and portable terminal shows sets up the remaining sum that is updated once more during the next outbound call in step e 2 at least.

More in general, in other is realized, the balance updates proactive command that transmits to portable terminal E7 by smart card sometimes at beginning of network, be to generate at beginning of management of balance device GS (push mode), and At All Other Times at beginning of smart card (pull mode (pull mode)), be the remaining sum backup and use the beginning of specific application SES to generate, and irrelevant with the detection incident.

In one implementation, new balance is shown in order to make more, and application program SES decides in its sole discretion:

Perhaps, regularly inquire manager GS to the request of network transmission E3 renewal proprietary file by triggering via portable terminal by the update request proactive command;

After perhaps during one or more scheduled events are being called out, indicating and detecting, transmit E3 via portable terminal to network and upgrade the proprietary file request, inquire manager GS by triggering by module DEV by terminal.

In another was realized, for example phone off-hook thereby Traffic Channel became occupied (the line is busy) or phone on-hook thereby Traffic Channel are eliminated scheduled events such as (clear down) by network, for example detected by the management of balance device GS that communicates by letter with HLR once more.This causes that server S CC takes message MSDA form to transmit more new balance to portable terminal in step e 5, and causes that smart card is shown described more new balance.

After scheduled event, when subscriber equipment is in holding state, also can transmit updating call consumption remaining sum SDA to subscriber equipment TM-CP at the beginning of manager GS.For example, scheduled event is that subscriber equipment TM-CP, part are by the indication of the incoming call of called subscriber's paying of subscriber equipment TM-CP and less than the remaining sum of being scheduled to remaining sum.Then, manager GS transmits and comprises the message of remaining sum, and requires subscriber authorisation to charge to (crediting of) user's calling consumption account, makes described user can receive this incoming call.

Scheduled event can also be any incident that finishes to set up outbound call, for example order to " IMSI separates (IMSI detach) " that smart card CP transmits by interface ICT, or because terminal exceeds network coverage, or because in fact call model at user's beginning deactivated (deactivated), is perhaps transmitted by network RR because of detach message (detach message).
