Description
Technical field
The present invention relates to POS(Point of Sale, point of sales terminal) terminal applied technical field, especially, relate to a kind of on POS terminal, realize business method, system and POS terminal.
Background technology
At present, the application program on POS is generally developed according to bank's demand by manufacturer, and bank is more extensive to the program management on it.Storage space on POS terminal is very limited, program on it is mainly divided into controlling application program, subapplication and POS manufacturer are by IC(Integrated Circuit both domestic and external, integrated circuit) three parts such as card financial payment authentication module, about financial payment certification, the standard of domestic application is PBOC 2.0(People Bank of China, People's Bank of China), external enforcement be EMV standard (EUROPAY, MASTERCARD, the initialism of VISA tri-international credit card companies, these three companies combine the IC-card debit/credit application standard of formulation, referred to as EMV standard).Wherein, mutual, the responsible adjective full dose of controlling application program primary responsibility POS terminal and bank's background system is downloaded and security control, collection terminal program state etc.; The deployment of a certain type service of subapplication primary responsibility bank on terminal; IC-card financial payment authentication module is responsible for the mutual of card and terminal.
For a long time, the banking of POS terminal deploy is always more single, is only to receive single business.In recent years, not only receive single business and have larger development, and all kinds of value-added services businesses and other third-party enterprise applied business have also had significant progress, made the application program on current POS terminal can not meet the needs of development, mainly comprise following some:
(1) how by the program on business need fast Development POS terminal
Generally, bank, when purchasing terminal product, arranges the program developed by manufacturer on POS terminal.Bank proposes general development requires to the program on POS terminal, does not carry out very concrete requirement to its framework and implementation.
Bank technology department, when receiving new business demand, first according to the POS using standard of bank, writes an online business demand and interface document based on 8583 message formats, describes the operation flow on POS terminal and bank's back office interface.Wherein, 8583 agreements are Information Exchange Agreements of the packet format based on ISO8583 message international standard, 8583 bags are made up of 128 field domain at most, there is unified regulation in each territory, and have fixed length and elongated dividing, 8583 bags above one section be bitmap, it is that packing unpacks the key replacement determining field domain, and 8583 agreements are many to be used in the information exchanging process on POS terminal and bank backstage.
There is a lot of drawback in this kind of mode: one is the restriction being limited by 8583 message formats, is beyond expression compared with the business implication of horn of plenty, the interface mode simultaneously also constraining background service to access; Two is that POS terminal program development process is not controlled, and need the longer development time to comparatively complicated program POS manufacturer, bank is uncontrollable; Three is after program development, the realization of all business demands has just been fixed up substantially, when the demand of bank changes, even a small business factor changes, all need remodify and compile original program, again the program on POS disposed and upgrade; Four are programs that each demand generates is full dose programs, cumulative along with business, and the routine data amount on POS terminal is increasing, and this just causes download also increasing; Five is exploitation and deployment of the third-party application do not supported except bank and POS manufacturer, bank is when branching out, if need to dispose third-party business, because the enforcement of third party's business demand is not in the contract range of bank and POS manufacturer, POS manufacturer will not develop, and bank does not have ability to develop alone yet.
(2) how rapid deployment POS terminal program
After program development on POS terminal, notifying bank of POS manufacturer carries out business acceptance and checkout, after banking is checked and accepted, program after examination is given business department by POS manufacturer, program is given to engineering department by business department more again, program is transmitted to engineering department of branch by business department's requirement by engineering department, program is transmitted to business department of branch by engineering department of branch, business department of branch generally adopts manual mode program to be installed on POS terminal, the equipment being put into trade company to cloth also will be visited in-site installation or fetch upgrading, and then again lays.
Due to the requirement of bank's fine-grained management and the demand of business innovation, there is a lot of shortcoming in above-mentioned way: one is that workflow is tediously long, and the program development on POS terminal is complete is put into trade company to cloth needs a very long business processing flow; Two is need to safeguard the program on POS terminal continually according to original pattern, program development, functional test and regression test etc. need a very long time, function add up also cause program to become increasingly complex, cause the program development cycle long, the demand that business markets to trade company can not to be met to the response time of demand; Three to be that program on POS terminal lays cost comparatively large, owing to being install manually, needs bank to pay a large amount of human costs; Four are inefficiencys, owing to being manually lay and need in-site installation to the equipment laid, cause laying efficiency lower, the demand higher to some pressing degrees, as upgraded mistake or laying the characteristic service of some special time period onsets by trade company's requirement, all can be helpless; Five is that remote update technology is immature, although the technical solution of some remote update POS terminal program in recent years, but due to the processing power that is limited by POS terminal and communication function restriction, and because the dynamic base degree of stability that circuit question, far-end in communication process are not controlled, full dose program download data amount is larger, different vendor downloads is different, circuit data transmission quality is disturbed, transmit the many factors such as unstable, cause practical application effect very undesirable.
(3) how to support that IC-card is concluded the business
2011, domestic each big bank all started the hair fastener of IC-card and accepts business.POS tool is in order to support that the IC-card of international card accepts, and each manufacturer POS tool all can by international EMV related specifications certification.By authentication requesting, if changed to some extent the program by the certification of EMV specification, then must certification again, otherwise if there is dispute, the side not pressing code requirement is party responsible, bears total loss by it.
Therefore, for supporting accepting of domestic IC card business, bank must handle the problem of following several respects well: one is how to use the existing IC-card of POS terminal to accept module to support accepting of domestic IC-card; Two are, how to avoid the renewal of service logic from now on and cause manufacturer's relative program need the problem of certification again.

TMS(Terminal Management System, terminal management system) be the system managing POS terminal remote download application program and parameter, it carries out management and control to POS terminal program, comprise the distribution management of existing conventional P OS program, parameter, file etc., POS program remote download and renewal, terminal program version management, terminal program rapid deployment; Management and control is carried out to POS terminal business, comprises business fast Development and test, business rapid deployment etc.
In the prior art, the factor affecting TMS remote download comprises:
(1) terminal operator is uncontrollable: POS terminal is deployed in trade company, and terminal operator is the personnel of trade company, Bu Shi bank personnel, and about needing program updates and the attended operation of Attended mode, bank cannot arrange operating personnel to carry out relevant maintenance work;
(2) terminal environments and state uncontrollable: because POS terminal is deployed in trade company, so trade company determines when startup and shutdown, what does after start, and download program carries out when needing terminal to be in idle condition, program updates needs POS to apply the state after being in clearing, and these are all uncontrollable;
(3) asynchronous communication requires very high to line quality: POS terminal is when carrying out download program, in order to improve download efficiency, require to use asynchronous communication mode, asynchronous communication mode is very high to the quality requirements of communication line, and POS generally adopts phone dialing mode to carry out communication, therefore, the quality of communication line directly affects the success ratio of download;
(4) download program overlong time: according to the standard configuration of POS terminal, the asynchronous communication baud rate that POS is stable is 31200bps, the theoretical download time of the POS full dose program of 1MB is clock more than 4.5 points, and download program needs the long period, also causes teleprogram to download easily failure;
(5) stability of each manufacturer remote download dynamic base is relied on: POS download program, the POS program of different vendor needs the dynamic base using respective manufacturer to provide, the degree of stability in each Manufacturer News storehouse is inconsistent, causes the POS download program success ratio of different vendor also different.
In conjunction with possibility Problems existing in above-mentioned remote download, the following embodiment of the present invention considers how to solve the problem from the following aspects:
(1) possibility of download program is reduced: from investigation in the early stage situation of the project implementation, POS terminal program full dose, asynchronous system download success ratio is lower, effect is poor and the comparatively not successful solution of industry, therefore, as far as possible the preferred plan of head it off reduce the possibility that POS terminal program adopts the download of asynchronous communication mode full dose, particularly, can realize from the following aspects:
(1a) application deployment: namely POS terminal application program carries out renewal and the compiling of full dose no longer according to demand, but adopt the mode of business configuration to carry out, when there being new demand, only change the configuration of original business or Added Business, can realize amendment or newly-increased POS apply, when designing the application program of POS terminal, the decomposed often changed according to business demand in application is become some class resources, as required these resources are reconfigured again, namely define the business procedure of various different application scene; When there being new demand, the object upgrading application program just can be reached by means of only increasing or redefine and configure application resource newly, and when carrying out program updates, only download the renewal that these resources changing or increase newly can realize program on POS terminal, significantly can reduce the download of program updates;
(1b) more new business is applied: adopt the POS application program that configuration mode generates, as long as pass through trading channel when upgrading, synchronous communication mode is adopted to download some controling parameters from backstage TMS, the renewal of program on POS terminal can be realized, such as, if application has increased the printing key element of the receipts list receipt of a business newly, the resource of single receipt is received in printing realization only need being changed this business, the POS terminal of all this resources of deployment finds that there is resource to be needed to download when registering, namely initiated the download of resource by synchronous communication pattern at once, resource needed for being downloaded by the pattern initiating a resource download request business, all resources on POS terminal are all downloaded by synchronous communication pattern, and the downloading mode of program is generally undertaken by asynchronous communication mode,
(1c) applied logic is received: POS terminal is when a process concrete business, main need carry out man-machine interaction, the information interaction of POS terminal and TMS, and IC-card card and POS terminal is mutual, the Service control logic of conventional P OS program is on POS terminal, after gathering a card account, it proceeds to account or produces account, terminal needs to provide clear and definite answer, and be placed on to specify in message territory and pass to TMS service end, this causes service logic to be bundled on POS terminal, as service logic slightly changes, then require that POS terminal revises full dose program, therefore, this partial service is received TMS service end by the present invention in logic, thus reduce the possibility of terminal program updates, after service logic is received, POS terminal is only responsible for by the resource issued in advance (such as, operation flow) image data, the business implication of concrete data is resolved by TMS service end, check that legitimacy is later by the requirement forwarding data of TMS Batch Processing system, after receiving the reply data of operation system, form response message by business need and be transmitted to POS terminal, by POS terminal analytic message, and carry out subsequent treatment to complete whole operation flow according to the every resource be preset on POS terminal.
Fig. 1 is the schematic flow sheet that the present invention realizes an embodiment of the method for business on POS terminal.
As shown in Figure 1, this embodiment can comprise the following steps:
S102, is cured on POS terminal by primary control program and sub-utility control program, and wherein, primary control program mainly realizes the POS terminal function relevant to TMS, carries out message exchange, office terminal program is installed, upgrades, deletion etc. with TMS; Sub-utility control program controls by master control application management.
S104, all kinds of resources on POS terminal needed for pre-configured execution miscellaneous service, wherein, all kinds of resource comprises data dictionary, basic resource, menu resource and process resources.
Particularly, basic resource can include but not limited to printing template information, indicating template information, application parameter, trade company's parameter, function prompt information, operation prompt information, miscue information, index information, business processing daily record, list of labels information, authentication center's PKI, terminal applies information, environmental variance, the positive information of punching, business verification information, clearing daily record, script advise fate, advertised information and logos information.
Menu resource is the resource collection for showing and drive operation flow for the customization of POS terminal, menu can be set to level Four, wherein, can establish at most 9 further menu, every further menu can establish at most 9 second-level menus, and every second-level menu can establish at most 9 three-stage menus, every three-stage menu can establish at most 9 level Four menus, the sum of menu item is no more than 200, in this menu structure, and the corresponding a kind of business of each leaf node.Menu memory block can be set up, for depositing menu relevant information on POS terminal.
Process resources is the set of the whole operation flows for the customization of POS terminal.Process resources comprises operational code collection and parameter set, and wherein, operational code determines the concrete n-back test of each operation steps, the execution of state modulator respective operations code and execution result.Operation flow is the part or all of performing step having described concrete business, its attribute comprises: service code, process mark, Business Name, function prompt index, main flow and sub-process etc., particularly, service code unique identification operation flow, main flow is the operational code collection that performs immediately after selection business and its parameter set, and sub-process is the operational code collection and its parameter set that perform under given conditions according to running status in main flow implementation.Wherein, a concrete flow process can include but not limited to operational code collection and parameter set.
Operational code collection is made up of operational code number and one or more sequence of opcodes; Operational code is made up of instruction and operation prompt information, describes a concrete operation; Instruction is the abstract of terminal specific behavior, and the numbering of distributing for each behavior is instruction number; Instruction sequences number is in flow performing process, to the numbering that the sequencing of instruction operation carries out; Parameter set is made up of order parameter sequence, with instruction one_to_one corresponding in operational code; Parameter is and instruction input or output parameter one to one, and the parameter sent under TMS is the input parameter of instruction, and the parameter that POS terminal send is instruction output parameter.
Data dictionary is for describing the attribute information of POS terminal data element used when the business of execution, and the definition of all data elements meets ISO/IEC 8825 standard and the definition of compatible BER-TLV data object.Wherein, operational code is also a kind of data element, comprises the definition of all data needed for POS terminal in data dictionary.POS terminal is explained by the definition of data element in data dictionary and the operation such as the computing of correct this data element of process and data display.
S106, POS terminal is after sign-out, if want to bring into use, need to go to register to TMS, registering, operator successfully just can operate POS terminal, in response to registering of POS terminal, judge whether need upgrade all kinds of resource and/or whether need to download new resource, now, version number current on the version number of all kinds of resources that POS terminal reports by TMS and backstage TMS compares, under normal circumstances, along with the renewal of version, version number increases gradually, the version number reported as POS is less than the version number on TMS, then determine to need all kinds of resources on POS terminal to carry out synchronously.
S108, as need be upgraded all kinds of resource and/or downloading new resource, then carries out synchronous with the mutual of the POS access gateway subsystem in TMS to all kinds of resources on POS terminal by primary control program, to download new resource and/or to upgrade all kinds of resource.
S110, sub-utility control program performs the flow process corresponding with selected business based on the business of all kinds of resource and selection.
POS terminal, after having gathered data, may perform following three flow processs:
(1) online: to determine subsequent treatment according to response result, comprise execution postpositive disposal, namely confirm and terminate current business, then initiate new business; Additional sub-stream journey, does not namely terminate current business, then initiates new business; Confirm and terminate current business;
(2) not online: winding-up or carry out off-line processing;
(3) online failure: perform OF(offline, off-line) sub-process.
Particularly, as shown in Figure 2, step S110 can be realized by following steps:
S202, the menu resource that sub-utility control program customizes according to POS terminal shows the menu comprising miscellaneous service, and wherein, whether each menu item can have at the attribute of screen display;
S204, receive user-selected menu item information, from process resources, the operation flow corresponding with selected menu item is obtained according to the flow process code that selected menu item is bound, based on the performing an action of Business Process Control POS terminal of data dictionary, basic resource and acquisition, and record the parameter gathered in implementation;
S206, POS terminal by the mode of operational code collection and parameter set and POS access gateway subsystem mutual, such as, after obtaining the parameter gathered, POS terminal can exchange data by operational code collection and parameter set mode, message is sent request to POS access gateway subsystem, also data are exchanged by operational code collection and parameter set mode and POS terminal after TMS process, response message is fed back to POS terminal, POS terminal performs an action according to the Row control POS terminal in response message, if necessary, POS terminal can also send request message according in the instruction again in response message.
POS terminal program Solidification is a primary control program and a sub-utility control program by this embodiment, TMS is that POS terminal has prepared a set of menu, flow process, display and print resource and some other basic resource, above-mentioned two control programs complete the application function on POS terminal according to these resources, reach the object of customization POS terminal application.Secondly, the operational code collection that POS terminal can also be used when flow performing and parameter set deliver to TMS, with the concrete business implication by TMS interpreter operation code and institute's image data, can also be simultaneously that POS terminal issues subsequent operation instruction according to business need, and then realize target that service logic is received.
Fig. 3 is the schematic flow sheet that the present invention realizes another embodiment of the method for business on POS terminal.
As shown in Figure 3, step S302-S310 corresponds to the step S102-S110 in Fig. 1, after step S310, can also comprise the following steps:
S312, after the main flow of business is finished, can judge whether to need to carry out in-line processing according to process mark, wherein, process mark is the controlled attribute of flow performing process, is automatically processed, do not controlled by instruction by POS terminal according to identification conventions;
S314, as need in-line processing be carried out, then the parameter set of the operational code collection performed on POS terminal and collection is reported POS access gateway subsystem, by POS access gateway subsystem, the operational code collection received and parameter set are resolved, and whether feedback performs next flow process and performs which flow process, as online failure, then perform processed offline sub-process;
S316, as without the need to carrying out in-line processing, then current business flow process is disposed or by off line business flow processing, now, the release of POS terminal and the related resource being closed in application in process of service execution and opening.
As can be seen from this embodiment, operational code collection in the present invention and parameter set make an explanation by POS access gateway subsystem, therefore, when demand has small variations, POS terminal refresh routine may not be needed, but undertaken reinterpreting by POS access gateway subsystem, the change of demand can be supported so to a certain extent more neatly.
Fig. 4 is the schematic flow sheet that the present invention realizes the another embodiment of the method for business on POS terminal.
