Embodiment
For problems of the prior art, the embodiment of the present invention provides a kind of message transmission method, this method application
In the network including POS machine, access device and multiple service servers.Application scenarios using Fig. 1 as the embodiment of the present invention show
It is intended to, POS machine A and POS machine B are linked on access device by interchanger, and access device is respectively connected to industry by wide area network
In server A of being engaged in and service server B.Wherein, service server A and service server B can be the front end processor of bank, business
Server A and service server B all can be Unix/Linux servers, the service server as POS machine.
Under above application scene, as shown in Fig. 2, the message transmission method specifically includes following steps：
Step 201, access device safeguards mapping item.
In the embodiment of the present invention, the corresponding pass between index mark and the application identities of APP is have recorded in the mapping item
System, the index identify the part for being specifically including but not limited to the calling number of POS machine or the calling number of POS machine.
Wherein, APP is specially an application connection, and based on this application connection, access device can take with corresponding business
Business device establishes connection.
For each APP, APP corresponds to a service server, and APP has unique application identities, and multiple APP can be with
Same service server is corresponded to, and the address information of the corresponding service servers of APP, the business can be recorded on access device
The address information of server can include：The corresponding IP address of service server and port information etc..Wherein, when multiple APP pairs
When answering same service server, the corresponding IP address of this multiple APP is identical, but the corresponding port informations of this multiple APP are different.
For example, maintain 3 APP on access device, the application identities of APP1 are application identities 1, the corresponding business of APP1
Server is service server A, and the address information of service server A is address A (i.e. IP address A+ ports 1)；The application of APP2
Application identities 2 are identified as, the corresponding service servers of APP2 are service server A, and the address information of service server A is address
A ' (i.e. IP address A+ ports 2)；The application identities of APP3 are application identities 3, and the corresponding service servers of APP3 are business service
The address information of device B, service server B are address B (i.e. IP address B+ ports 3).
In the embodiment of the present invention, administrator configures APP information on access device, and (application identities and APP of APP are corresponding
The address information of service server) and mapping item, pair between mapping item recording indexes mark and the application identities of APP
It should be related to.
When access device safeguards the correspondence between index mark and the application identities of APP in mapping item, access
Equipment can be recorded in mapping item for accurate matched index mark, and being used for accurate matched index by this identifies,
Unique POS machine can be matched, to improve matched accuracy.For example, when POS machine calling number be 12345678, should
The corresponding APP of POS machine is APP1, and the corresponding index of application identities 1 is identified as when being used for accurate matched index mark, should be answered
It is specially 12345678 with the corresponding index mark of mark 1, and mapping item is as shown in table 1.
When the quantity of POS machine is very much, to reduce the scale of mapping item, access device safeguards index in mapping item
When identifying the correspondence between the application identities of APP, access device can also be recorded in mapping item for fuzzy
The index mark matched somebody with somebody, the index that fuzzy matching is used for by this identify, it is possible to reduce the scale of mapping item.Wherein, this is used for
The index mark of fuzzy matching can be configured by combining asterisk wildcard, started with keyword match or ended up content (such as
First 4, first 2 etc. of calling number of calling number).For example, when POS machine A calling number be 11115678, POS machine B's
Calling number is 11111234, and POS machine A and the corresponding APP of POS machine B are APP2, and the corresponding index of application identities 2 identifies
During to be identified for the index of fuzzy matching, the corresponding index mark of the application identities 2 specially 1111****, and mapping item
As shown in table 2.
The index mark in mapping item can not be matched in order to prevent, so as to cause access device not know how to send
The problem of POS transaction connection request messages, access device is safeguarded in mapping item between index mark and the application identities of APP
Correspondence when, access device can also be recorded in mapping item for it is default it is matched index mark, be used for by this
Default matched index mark, it is ensured that all POS machine can match the record in mapping item.For example, for lacking
Save matched index and be identified as sky, and the corresponding index of application identities 3 of APP3 is identified as default matched index mark
When, then mapping item is as shown in table 3.
Table 1
| Index mark | Application identities |
| 12345678 | Application identities 1 |
Table 2
| Index mark | Application identities |
| 12345678 | Application identities 1 |
| 1111**** | Application identities 2 |
Table 3
| Index mark | Application identities |
| 12345678 | Application identities 1 |
| 1111**** | Application identities 2 |
| It is empty | Application identities 3 |
Step 202, access device receives the POS transaction connection request messages that POS machine is sent.Wherein, POS transaction connection
The device identification of POS machine can be at least carried in request message.
Further, the device identification of the POS machine is specifically including but not limited to the calling number of POS machine.
Under the POS access ways that dial, POS machine sends POS transaction after response user card punching operation, to access device and connects
Request message is connect, and the calling number of POS machine is carried in POS transaction connection request messages, POS machine hair is received by access device
The POS transaction connection request messages sent.
Step 203, access device is obtained from mapping item and set with POS machine after the device identification of POS machine is obtained
It is standby to identify the corresponding application identities of matched index mark.
In embodiments of the present invention, access device is obtained with the device identification of POS machine (such as from mapping item：POS machine
Calling number) matched index identifies the processes of corresponding application identities, it is specifically including but not limited to following manner：Access device
Judge to whether there is in mapping item the completely matched index of the device identification with POS machine to identify；If there is completely matched
Index identifies, then access device obtains completely matched index from mapping item and identifies corresponding application identities；If do not deposit
Identified in completely matched index, then access device is determined whether in mapping item with the presence or absence of the device identification with POS machine
The matched index mark in part；Identified if there is the matched index in part, then access device fetching portion from mapping item
Matched index identifies corresponding application identities；If there is no the matched index mark in part, then access device is from mapping table
Obtained in and specify application identities.
Wherein, the priority for accurate matched index mark is higher than the preferential of the index mark for fuzzy matching
Level, the priority for the index mark of fuzzy matching are higher than the priority for being used for default matched index mark.Based on this, connect
Enter equipment after the device identification of POS machine is obtained, access device is first determined whether in mapping item with the presence or absence of completely matched
Index mark, i.e., matching is used for accurate matched index mark first；If there is no completely matched index mark, then access
Equipment can be just judged in mapping item with the presence or absence of the matched index mark in part, i.e. index mark of the matching for fuzzy matching
Know；If there is no the matched index mark in part, then access device obtains directly from mapping item specifies application identities, i.e.,
It is the application identities corresponding for default matched index mark that this, which specifies application identities,.
For example, access device obtain POS machine device identification be 12345678 after, based on the mapping table shown in table 3
, due to there is the completely matched index mark 12345678 of the device identification 12345678 with POS machine in mapping item,
Access device obtains 12345678 corresponding application identities (application identities 1) of matched index mark completely from mapping item.
And for example, access device is after the device identification for obtaining POS machine is 11112546, based on the mapping item shown in table 3, due to reflecting
The completely matched index of the device identification 11112546 with POS machine is not present in firing table item to identify, but there is the equipment with POS machine
The matched index mark 1111**** in 11112546 parts is identified, therefore access device fetching portion from mapping item is matched
The corresponding application identities (application identities 2) of index mark 1111****.For another example, access device is obtaining the device identification of POS machine
After 12546987, based on the mapping item shown in table 3, since the device identification with POS machine being not present in mapping item
12546987 completely matched index marks, are also not present and are marked with the matched index in 12546987 part of device identification of POS machine
Know, therefore obtained from mapping item and specify application identities, is i.e. the corresponding application identities 3 of index mark " sky ".
In the embodiment of the present invention, after access device receives the POS transaction connection request messages that POS machine is sent, if POS
The device identification of POS machine is not carried in transaction connection request message, then access device is obtained to specify directly from mapping item and answered
With mark, the i.e. corresponding application identities 3 of index mark " sky ".Wherein, for do not support set calling number POS machine, the POS
In the POS transaction connection request messages that machine is sent to access device, the device identification of POS machine will not carried.
Step 204, access device selects a untapped E1POS sub-interface from E1POS interfaces, and passes through E1POS
Sub-interface sends POS transaction connection request messages to the corresponding service server of application identities of acquisition, to be connect by E1POS
Message between mouth transparent transmission POS machine and the service server.
E1POS interfaces are a kind of highly integrated Digital Private Line interfaces based on E1 interfaces, and an E1POS interface includes 30
E1POS sub-interfaces, based on this, access device can arbitrarily select a untapped E1POS sub-interface from E1POS interfaces.
Since each APP has corresponded to a service server, and APP has unique application identities, therefore, from mapping item
After getting application identities, according to the ground of the corresponding service servers of the corresponding APP of the application identities recorded on access device
Location information, access device can know the corresponding service server of the application identities.Further, access device can pass through choosing
The E1POS sub-interfaces selected, and based on the address information of the corresponding service server of application identities, sent to the service server
POS transaction connection request messages.For example, the application identities of APP1 are application identities 1, the corresponding service servers of APP1 are business
Server A, the address information of service server A is address A, it is assumed that the application identities obtained in step 203 are application identities 1,
The E1POS sub-interfaces currently selected are E1POS sub-interfaces 1, and by E1POS sub-interfaces 1, to address A, (i.e. business takes access device
Be engaged in device A) send POS transaction connection request messages.Based on above-mentioned processing, access device is between POS machine A and service server A
Dedicated communication link is established, POS machine A is communicated with service server A by the dedicated communication link, that is, passes through E1POS
Message between interface 1 transparent transmission POS machine A and service server A.Until sign off, access device release E1POS sub-interfaces 1.
Based on above-mentioned technical proposal, in the embodiment of the present invention, by safeguarding that being used for recording indexes identifies on access device
The mapping item of correspondence between the application identities of APP, so that when receiving POS transaction connection request messages, from
Acquisition and the matched index corresponding application identities of mark of the device identification of POS machine in mapping item, and pass through E1POS sub-interfaces
POS transaction connection request messages are sent to the corresponding service server of application identities of acquisition.Aforesaid way proposes a kind of E1POS
The dynamic transparent transmission matching mechanisms of sub-interface, improve the transparent transmission flow of existing E1POS sub-interfaces, effectively make use of E1POS
The highly integrated advantage of sub-interface, and suitable for there are the networking of multiple service servers.Further, aforesaid way will not
Cause access device to establish the dedicated communication link of mistake, and avoid the message transmission of POS machine to irrelevant business service
Device, so that the problems such as solving Fail Transaction and Transaction Information leakage.
For example, when the message of POS machine A needs to pass through service server A, access device when safeguarding mapping item,
Index is identified as the calling number 12345678 of POS machine A, and application identities are the application identities 1 of the corresponding APP of service server A.
Based on this mapping item, access device is when the POS for receiving POS machine A transmissions merchandises connection request message, from mapping item
It is application identities 1 to obtain with the matched index corresponding application identities of mark of the device identification 12345678 of POS machine A.Further
, access device selects a untapped E1POS sub-interface 1 from E1POS interfaces, and by E1POS sub-interfaces 1 to application
Identify 1 corresponding service server A and send POS transaction connection request messages, so as to be built between POS machine A and service server A
Vertical dedicated communication link.Aforesaid way will not cause access device to establish the dedicated communication link of mistake, be lost so as to solve transaction
Lose the problems such as being revealed with Transaction Information.
