Description
[technical field]
The present invention relates to a kind of POS system that is used for the financial settlement field, relate in particular to a kind of grouping implementation method of on the POS access server, carrying out.
[background technology]
The POS terminal is connected with the bank main system by IP network.During work, bank card " is swiped the card " on the POS terminal and input relevant business information (type of transaction, dealing money, password etc.), give bank main the relevant business information that is obtained by the POS access network by the POS terminal, after the process bank main carries out respective handling, return result to the POS terminal, thereby finish a transaction.
Because the POS business of swiping the card is convenient, fast, can shorten the time of transaction to a great extent, the POS business of swiping the card has all obtained using widely in various fields such as telecommunications, finance, commerce and trade, traffic, social security, medical treatment, health care, the tax, public security, customs, industry and commerce, organization mechanism code and urban service management.
Figure 1 shows that a kind of POS business network structure, bank wherein finishes the POS business of swiping the card by the independent groups net mode.The holder swipes the card by the POS terminal of built-in MODEM chip, the POS terminal is connected to the POS access server by public telephone network (PSTN) or wireless network (GSM/GPRS), set up the transaction path by the POS access server by IP network and corresponding bank POS front end processor and bank transaction main frame again, finish function such as transferring of the information management of card and account through bank main after, by POS front end processor and POS access server the essential information of transaction is passed to the POS terminal again, the POS terminal can print the trading processing result to the holder, promptly finishes a transaction.The calorie requirement that the shortcoming of present technique the is different bank transaction of on the POS terminal of bank separately, just swiping the card.
Along with the unification of financial industry and the application demand development of user POS business, the network of POS service access is also gradually based on Unionpay's pattern.Figure 2 shows that Unionpay unifies POS business network structure under the pattern.Compare with last technology, unify under the pattern in this Unionpay, the card of different bank can be concluded the business in same POS terminal.
The transaction data message adopts the VISA message format between POS terminal and POS front end processor (a certain bank POS front end processor or the POS of Unionpay front end processor), as shown in Figure 3, comprise start bit STX, message length LEN, TPDU TPDU, transaction data, position of rest ETX and verification and LRC in the message, wherein the length of TPDU TPDU is 5 bytes, and its transformat is 0x ' xxxxxxxxxx '.Its effect is to distinguish different banks as bank identifier, and first byte is " 0x60 ", and other bytes change according to different bank.Adopt TCP to be connected between the POS front end processor of POS access server and bank and transmit data, the POS access server divides into groups according to the TPDU of POS transaction data message, the IP address of configuration bank POS front end processor, port numbers and to TPDU that should bank on the POS access server.POS business realizing flow process is as follows:
The first step, call setup: the user swipes the card on the POS terminal, and the POS terminal makes a call, and calls out by setting up between cable/radio telephone set network and POS access server.
Second step, MODEM consult: carry out the negotiation of bottom MODEM between POS terminal and POS access server.
The 3rd step, link layer are set up: carry out link layer negotiation between POS terminal and POS access server and set up.As synchronous SDLC, async-ppp etc.
The 4th step, POS user grouping: after POS physical layer, link layer negotiation were passed through, the POS access server was received the transaction data message that the POS terminal sends, and parsed POS terminal use's TPDU according to message format POS access server.The POS access server finds corresponding bank's grouping according to TPDU.
The 5th step, TCP connect foundation: the POS access server is set up TCP with the POS front end processor that bank divides into groups and is connected.
The 6th step, transaction data transmitting-receiving: after TCP connected foundation, the POS access server sent to the POS front end processor with the data of POS terminal by the TCP connection.The POS front end processor is transmitted to bank accounting system main frame (HOST) to Transaction Information and handles, and is transmitted to the POS access server by the POS front end processor again after disposing.The POS access server is the data of the POS front end processor that receives, according to sending to the POS terminal use behind the protocol analysis.
The 7th step, call tear down: the POS terminal is finished transaction, and dismantling call initiatively, POS access server are removed and being connected and discharging resource of front end processor.
Mainly there is the shortcoming of two aspects in prior art:
When 1, the POS terminal inserted, in physical layer and link layer negotiation stage, the POS access server also can't obtain user's TPDU grouping, can't connect with the bank POS front end processor of corresponding grouping.Must wait for after link layer is set up the transaction data message of successfully receiving the POS terminal and could start TCP foundation.
2, the POS access server application layer data message that need resolve POS transaction just can obtain POS user's TPDU, and making the POS access server handle may to cause when complexity and application layer protocol change can't be compatible.
Because require transactions velocity fast when the user uses the POS terminal transaction, exchange hour is short, so the processing speed to each function device in the POS access network requires all than higher.But because the existence of these two shortcomings after the POS access server must wait for that POS terminal physical layer and link layer negotiation are passed through, receives that the transaction data of POS terminal just can divide into groups and set up TCP with the bank POS front end processor to be connected; Make the time of transaction elongated, what be unfavorable for concluding the business carries out in real time.And the POS access server also needs to resolve POS transaction data message, relates to the protocol processes of application layer more complicated, in case the POS access server must carry out compatible modification when agreement changes, makes troubles to networking.
