Abstract
The invention relates to a method for multiplexing frequency shift keying (FSK) communication equipment and a communication line. The method is characterized by comprising the following steps that: point of sale (POS) terminals of different application are connected to the same set of FSK communication gateway system through the same E1 line and the same set of communication equipment, and the FSK communication gateway system performs transaction message routing according to routing control domains in transaction messages between the POS terminals and background service systems, and transmits the transaction messages to different background service systems, wherein the format of each transaction message is 'message length + routing control domain + transaction message'. The POS terminals bearing different application can be flexibly connected to different background service systems through the same E1 line, the same communication equipment and the same set of FSK communication gateway system according to parameter settings of the POS terminals and the FSK communication gateway system, so that the communication equipment and the communication line are multiplexed.
Description
Technical field
The present invention relates to a kind of FSK communication apparatus and the multiplexing implementation method of communication line.
Background technology
During POS terminal employing FSK mode communication, complete the conversion of FSK communications protocol and TCP/IP communications protocol by the communication apparatus such as sound card or multimedia switchboard and FSK Communication Gateway system, realize the data interaction with Batch Processing system by the E1 relaying special line of communication operator.Under this architecture, POS terminal can only access a Batch Processing system, completes specific business function.When POS terminal needs access another one Batch Processing system to complete other business functions, often need to build a set of FSK Communication Gateway system in addition, or adapted to by the original FSK Communication Gateway system of amendment, cause overlapping investment and the wasting of resources, be not easy to the Function Extension of POS terminal.
Summary of the invention
In view of this, the object of this invention is to provide a kind of FSK communication apparatus and the multiplexing implementation method of communication line, the multiplexing of communication apparatus and communication line can be realized.
The present invention adopts following scheme to realize: a kind of FSK communication apparatus and the multiplexing implementation method of communication line, it is characterized in that: the POS terminal of different application is accessed same set of FSK Communication Gateway system by same E1 circuit, same set of communication apparatus, carry out transaction message route by described FSK Communication Gateway system according to the routing control field in the transaction message between POS terminal and background system, be sent to different Batch Processing systems; The form of described transaction message is " message length+routing control field+transaction message ".
Further, described routing control field is made up of identifier, destination address DA, source address OA.
Further, described message length is 2 bytes, and described routing control field is 5 bytes, and described identifier is hexadecimal 80,1 byte, and described destination address DA is 2 bytes, and described source address OA is 2 bytes.
Further, described source address OA is by described FSK Communication Gateway system assignment, carry out source side for identification message, to carry out addressing accordingly during the response message of FSK Communication Gateway system platform operation system upon receipt, response message is issued the POS terminal of the request of initiation;
Described destination address DA is distributed according to the application of POS terminal by user, for the target side of identification message, and namely corresponding Batch Processing system.
Further, the setting of described destination address DA is the destination address being arranged each application by user in POS terminal, and FSK Communication Gateway system is set up the mapping relations of destination address and Batch Processing system.
Further, mapping table corresponding to described mapping relations is made up of destination address DA+ service IP+service port number.
The present invention by increasing routing control field in transaction message head, and transaction message route is carried out according to routing control field in FSK Communication Gateway system, different application in such POS terminal can by same E1 circuit, same set of communication apparatus, same set of FSK Communication Gateway system by POS terminal and the optimum configurations of FSK Communication Gateway system be routed to different Batch Processing systems, thus realize communication apparatus and communication line is multiplexing.
Accompanying drawing explanation
Fig. 1 is the system architecture schematic diagram connected according to the embodiment of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention will be further described.
The present embodiment provides a kind of FSK communication apparatus and the multiplexing implementation method of communication line, it is that the POS terminal of different application is accessed same set of FSK Communication Gateway system (as shown in Figure 1) by same E1 circuit, same set of communication apparatus, carry out transaction message route by described FSK Communication Gateway system according to the routing control field in the transaction message between POS terminal and background system, be sent to different Batch Processing systems; The form of described transaction message is " message length+routing control field+transaction message ".
In the present embodiment, wherein said message length is 2 bytes, by identifier (hexadecimal 80 in described routing control field the present embodiment, 1 byte), destination address DA (2 bytes, Destination Address is called for short), source address OA (2 bytes, Originator Address is called for short) totally 5 bytes composition.Wherein said source address OA, by described FSK Communication Gateway system assignment, carrys out source side for identification message, to carry out addressing accordingly during the response message of FSK Communication Gateway system platform operation system upon receipt, response message is issued the POS terminal of the request of initiation; Described destination address DA is distributed according to the application of POS terminal by user, for the target side of identification message, and namely corresponding Batch Processing system.
Be noted that in the present embodiment, the setting of described destination address DA is the destination address being arranged each application by user in POS terminal, and FSK Communication Gateway system is set up the mapping relations of destination address and Batch Processing system.Mapping table corresponding to these mapping relations is made up of destination address DA+ service IP+service port number.Concrete:
[IP TABLE]
-1, 22.80.102.175, 1000
00 06, 22.80.102.176, 2000
01 08, 22.80.102.180, 3000；
Above-mentioned route mapping table represents, destination address be " x00 x06 " POS application by IP address be 22.80.102.176, service port number be 2000 the process of Batch Processing system; And destination address be " x01 x08 " POS application by IP address be 22.80.102.180, service port number be 3000 the process of Batch Processing system; Other POS apply by IP address be 22.80.102.175, service port number be 1000 the process of acquiescence Batch Processing system.
The foregoing is only preferred embodiment of the present invention, all equalizations done according to the present patent application the scope of the claims change and modify, and all should belong to covering scope of the present invention.
