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
When the communication of FSK mode is adopted at the POS terminal; Accomplish the conversion of FSK communications protocol and TCP/IP communications protocol by communication apparatus such as sound card or multimedia switch and FSK Communication Gateway system, realize and the data interaction of backstage operation system through the E1 relaying special line of communication operator.Under this architecture, a backstage operation system can only be visited in the POS terminal, accomplishes specific business function.When other business functions of another one backstage operation system completion need be visited in the POS terminal; Often need to build in addition a cover FSK Communication Gateway system; Or, caused the overlapping investment and the wasting of resources through the adaptation of the original FSK Communication Gateway of modification system, be not easy to the function expansion at POS terminal.
Summary of the invention
In view of this, the purpose of this invention is to provide a kind of FSK communication apparatus and the multiplexing implementation method of communication line, can realize the multiplexing of communication apparatus and communication line.
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: same set of FSK Communication Gateway system is inserted through same E1 circuit, same set of communication apparatus in the POS terminal of different application; Carry out the transaction message route by said FSK Communication Gateway system according to the routing control field in the transaction message between POS terminal and the background system, be sent to different backstage operation systems; The form of said 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 said routing control field is 5 bytes, and said identifier is hexadecimal 80,1 byte, and said destination address DA is 2 bytes, and said source address OA is 2 bytes.
Further; Said source address OA is by said FSK Communication Gateway system assignment; Be used to identify the source side of message, so that FSK Communication Gateway system carries out addressing, the POS terminal of response message being issued initiation request in view of the above when receiving the response message of backstage operation system;
Said destination address DA is distributed according to the application at POS terminal by the user, is used to identify the target side of message, promptly corresponding backstage operation system.
Further, the setting of said destination address DA is through the user each application aims address to be set on the POS terminal, in FSK Communication Gateway system, sets up the mapping relations of destination address and backstage operation system.
Further, described mapping relations corresponding mapping table is made up of destination address DA+ service IP+service port number.
The present invention is through increasing routing control field in the transaction message head; And in FSK Communication Gateway system, carry out the transaction message route according to routing control field; Like this different application on the POS terminal can through same E1 circuit, same set of communication apparatus, same set of FSK Communication Gateway system by on the POS terminal and the parameter setting of FSK Communication Gateway system be routed to different backstage operation systems, thereby realize that communication apparatus and communication line are multiplexing.
Description of drawings
Fig. 1 is the system architecture sketch map that connects according to the embodiment of the invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Present embodiment provides a kind of FSK communication apparatus and the multiplexing implementation method of communication line; It is that same set of FSK Communication Gateway system (as shown in Figure 1) is inserted through same E1 circuit, same set of communication apparatus in the POS terminal of different application; Carry out the transaction message route by said FSK Communication Gateway system according to the routing control field in the transaction message between POS terminal and the background system, be sent to different backstage operation systems; The form of said transaction message is " message length+routing control field+transaction message ".
In the present embodiment; Wherein said message length is 2 bytes; Be by identifier (hexadecimal 80 in the said routing control field present embodiment; 1 byte), destination address DA (2 bytes, Destination Address be called for short), source address OA (2 bytes, Originator Address is called for short) totally 5 bytes form.Wherein said source address OA is used to identify the source side of message by said FSK Communication Gateway system assignment, so that FSK Communication Gateway system carries out addressing, the POS terminal of response message being issued initiation request in view of the above when receiving the response message of backstage operation system; Said destination address DA is distributed according to the application at POS terminal by the user, is used to identify the target side of message, promptly corresponding backstage operation system.
Be noted that in the present embodiment that the setting of said destination address DA is through the user each application aims address to be set on the POS terminal, in FSK Communication Gateway system, sets up the mapping relations of destination address and backstage operation system.This mapping relations corresponding mapping table 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 representes, destination address for " x00 " POS to use by the IP address be that 22.80.102.176, service port number are that 2000 backstage operation system is handled; And destination address for " x01 " POS to use by the IP address be that 22.80.102.180, service port number are that 3000 backstage operation system is handled; It is that 22.80.102.175, service port number are 1000 acquiescence backstage operation system processing that other POS use by the IP address.
The above is merely preferred embodiment of the present invention, and all equalizations of doing according to claim of the present invention change and modify, and all should belong to covering scope of the present invention.
