Description

Message transfer method, transfer device and terminal device in an online system

technical field

The present invention generally relates to the technical field of data transmission, and in particular relates to a message transfer method, transfer device and terminal device in an online system.

Background technique

With the application of network technology more and more widely, many of people's daily work and life needs are realized through networking. A message can be considered as the basic unit of network transmission, and each network communication node can organize the information to be sent into a data packet, that is, a message for transmission. The data packets transmitted in the information exchange network are usually constructed according to a specific communication protocol, such as the TCP/IP protocol or other data transmission protocols or specifications related to specific purposes. These protocols and specifications usually determine the length of the message, message field division, message field definition and other necessary content to establish effective communication.

In some network architectures, message transmission may require handoffs rather than point-to-point. For example, there is a central node in the star network structure, also known as the central switching station, and all other network devices are directly connected to the central node, and the communication between end users must pass through the central station. The application of network technology in the bank's inter-bank transaction system adopts such a star topology. All merchant terminals and the background processing systems of each bank are connected to an inter-bank transfer system. The transaction request message of the banking system is distributed to the corresponding destination, so that consumers can freely use the consumer card issued by any bank to pay on the merchant terminal and popularize inter-bank business. The above-mentioned inter-bank transfer process is shown in FIG. 1 .

The transmission in the network usually consists of multiple message fields, and each message field defines the data elements that need to appear in the request and response process. There are often a large number of these data elements, and each data element has finely specified value attributes and value ranges for specific applications. If you are not familiar with these regulations or have a biased understanding, it is often easy to lead to system development errors, which in turn cause network communication failures. Especially in a star-structured network such as a bank's inter-bank transaction system, the cause can only be located by checking each other between end users after a communication failure is found, and the problem can only be solved by remodeling the entire system, which not only consumes A large amount of manpower, material resources, and financial resources, and a long transformation cycle, make the system's work efficiency unable to improve for a long time.

Such problems are very common in the development of some special-purpose networking systems. In order to avoid system failure due to message construction errors, although an error correction mechanism has been set up at present, such as comparing with historical experience values stored in the database, etc., it is impossible to realize real-time monitoring of message errors in the online system.

Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the various structures in the drawings are only schematic illustrations, to enable those skilled in the art to best understand the principle of the present invention, and they are not necessarily drawn to scale.

The method or device provided by the present invention is suitable for message transmission in an online system, and is especially suitable for a situation where switching is required during message transmission, such as an online system with a star network. Taking the bank's inter-bank transaction system as an example, the message transfer method and device provided by the present invention are especially suitable for the inter-bank transaction transfer device, and the transaction requests from the transaction terminal or each bank processing system need to pass through the transfer device And reach the destination. Correspondingly, the features of the terminal equipment provided by the present invention can also be incorporated into the transaction terminal in the cross-bank transaction system or the processing systems of each bank.

Fig. 2 shows a schematic structure of a message switching device according to an embodiment of the present invention. As shown in FIG. 2 , the packet switching device 100 may include a checking unit 101 , an error correction unit 102 and a sending unit 103 .

Generally, the message transfer device 100 plays the role of information transfer in the online system, and transfers the message from the terminal node in the contact system to the destination node or other transfer devices. The method and device provided by the present invention are more preferably applicable to the situation where the message transfer device and the terminal node as the sender of the message can directly exchange information, but this is not necessarily necessary.

In the embodiment shown in FIG. 2 , the checking unit 101 may be configured to determine whether the message to be sent has a message field that does not conform to the communication specification complied with by the online system. Here, the online system can be, for example, a bank's inter-bank transfer transaction system, in which communication messages must be constructed in accordance with specific communication specifications. In some embodiments of the present invention, determining whether the message to be sent conforms to the specification may generally include two parts. First, a message unpacking process may be performed on the sent message according to the general message forwarding process. During the unpacking process, it is possible to find an abnormal message field structure, for example, a message field that should have a length of 10 bytes according to the specification only has 8 bytes, and the like. Secondly, regardless of whether there is an abnormal message field structure during the unpacking process, the compliance check of each message field obtained by unpacking is further carried out according to the specification, including checking whether the message includes all the fields required in the specification. Message field, that is, whether there is a problem of multiple fields or few fields, and check whether the length, content, and field value of each message field meet the specifications. Once a non-compliant message field is found, the inspection unit 101 can be configured to transmit the message to be sent and the information related to the non-compliant message field to the error correction unit 102 instead of the conventional message field As in the transfer process, it directly rejects the wrong message or directly sends out the message that only passes the unpacking.

The error correction unit 102 may be configured to perform an error correction process on a message to be sent having a message field that does not comply with a communication specification to generate an error-corrected message to be sent. In some embodiments of the present invention, the error correction process may include: generating an error correction request message based on the information associated with the non-compliant message field, calling the sending unit 103 to transmit the error correction request to the sender of the message to be sent message, and generates an error-corrected message to be sent in response to an error correction request reply from the message sender. For example, the error correction request message may include a message to be sent, an error message field identifier, and an error cause code, wherein the message to be sent is the originally received message itself, and the error message field identifier is used to indicate the message to be sent. Which message fields in the sent message do not conform to the specification, and the error reason code is used to indicate the problems existing in the message field, such as missing message fields, redundant message fields, wrong length or value type of message fields, and Errors such as message field value out of range.

In the online system applying the present invention, the message sender terminal device will be configured to return an error correction response in response to the error correction request generated by the error correction unit 102 . Fig. 3a shows a schematic structure of a message sender terminal device according to an embodiment of the present invention, and Fig. 3b shows its operation flow after receiving an error correction request. The terminal device structure shown in FIG. 3 a can be incorporated into any node terminal in the online system that wants to send messages via the message switching device 100 .

As shown in Fig. 3b, the terminal device 300 receives the error correction request message from the message transfer device 100, and may unpack it according to the general process of receiving a message (not shown in the figure). Furthermore, the content of the error correction request message can be sent to the error correction unit 301, which can be configured to generate a correction message for a previously sent error message in response to the error correction request message. According to the embodiment shown in FIG. 3 b , in the error correction unit 301 , it may first be determined whether there is a history record in the non-compliant message field that needs error correction. For non-compliant message fields with error correction records, correction messages can be generated directly based on error correction records; for non-compliant message fields without error correction records, default settings or real-time notifications can be used for manual processing , and the error correction history can be generated correspondingly. Finally, the sending unit 302 may be called to return the error correction response with the corrected message to the message switching device 100 .

In response to the error correction request response from the message sender device, the error correction unit 102 in the message switching device 100 will generally generate an error-corrected message to be sent and send it to the message to be sent through the sending unit 103. recipient of the text.

In some embodiments of the present invention, the error correction unit 102 may first extract the corrected version of the message to be sent from the content of the error correction response, and perform a service matching check on it. Furthermore, the error correction unit can locate the corrected message field and the corresponding correction value in the correction message returned by the sender. The corrected message field is compared with the non-compliant message field indicated in the error correction request, and if the non-compliant message field is corrected, the error correction unit 102 can forward the corrected message from the sender to the sender The unit 103 is to send to the recipient of the original message to be sent. In some embodiments, the error correction unit 102 may also forward the correction message to the checking unit 101 for checking again, that is, to determine whether the correction is successful. On the other hand, if it is found that the non-compliant message field in the original message to be sent has not been corrected by the sender, the error correction unit 102 will make a record and notify the sender device in the subsequent process through other processing units.

In the online system that needs to perform message transfer, by adding a unit for message field inspection and real-time error correction in the message transfer device, the relevant checks are performed on the message to be transferred based on the message field according to the communication specification. When there are errors related to message field attributes (such as length, value type), value, multiple fields, and few fields, it will enter the error correction unit. By sending an error correction request message online, the network access organization of the message sender will confirm and authorize the error correction content in the message field in real time, and return the corrected message to be forwarded by the message transfer device. The receiver of the message will be more likely to receive the information that the message field is configured correctly, thereby improving the working efficiency of the online system.

Those skilled in the art should understand that the unit division in Figure 2 and Figure 3a is only schematic, and the message switching device 100 provided by the present invention can be implemented in any way, as long as it can realize the above-mentioned units function.

Fig. 4 shows the flow of a message forwarding method according to an embodiment of the present invention. As shown in Figure 3, when the message switching device provided by the present invention receives a message from a certain terminal in the online system, it first unpacks the message to be sent according to the routine, which may include security Calibration and other routine processing. As described above, errors in the message field may be found during the unpacking process, such as multiple fields, few fields, wrong length of the message field, and the like. After the unpacking is completed, regardless of whether a message field error is found during the unpacking process, the process shown in Figure 4 will further determine whether there is a message field that does not meet the specification in the message, that is, determine that the message Whether each message field in conforms to the specified settings, such as message field length, value type, value range, etc.

Next, in the case that the message to be sent has a non-compliant message field, the error correction process described above in conjunction with Fig. 2 and Figs. 3a-3b is performed, thereby obtaining a message to be sent after error correction. In the embodiment shown in FIG. 4 , the error-corrected message to be sent may be further checked to determine whether there is still a message field that does not conform to the specification. The checking process can be consistent with the process of judging whether the original message to be sent has a non-compliant message field, including unpacking the error-corrected message to be sent, and unpacking each message field obtained by unpacking Conduct a compliance check. In the embodiment shown in FIG. 2 , the checking of the error-corrected message to be sent can also be completed by the checking unit 101 .

In practice, when the original message to be sent is found to have a non-compliant message field, a flag indicating that the message enters the error correction process can be set, for example, by setting a certain redundant bit in the original message to Set to "1" to indicate that the message has undergone an error correction process, or by adding a flag bit to the original message and setting it to "1" to indicate that the message has undergone an error correction process. This flag can always be kept in the error-corrected message to be sent, as to distinguish whether the message from the checking unit 101 with the non-compliant message field is from the sender's original message to be sent or the error-corrected message The basis for the message to be sent.

When the error-corrected message to be sent is determined to have no non-compliant message field, it will be directly sent to the receiver of the original message. On the contrary, when the error-corrected message to be sent still has a non-compliant message field, no error correction process will be performed on it. According to the embodiment shown in Figure 4, an error correction log can be recorded for the corrected message with a non-compliant message field, and the sender device can be notified in the subsequent process through other processing units, so as to facilitate error statistics and subsequent system correction . Further, it may also be determined whether to still send the error-corrected message to the receiver according to the error criticality of the non-compliant message field. For example, if the error in the non-compliant message field does not affect the business processing on the transfer device, the transfer device may consider the error to be less critical, so it can still choose to continue forwarding the error-corrected message. Otherwise, it can reply a failure response to the sender of the message. Taking the bank's inter-bank transaction system as an example, if the error of the non-compliant message does not affect the transfer and settlement on the inter-bank transfer device, the inter-bank transfer device can still continue to transfer the error-corrected message to the message receiver.

Figures 5a and 5b schematically show the application of the present invention in the bank's inter-bank transaction system, respectively. When performing cross-bank transfer processing on online transaction messages, if real-time error correction can be performed on the message field of the transaction message from the perspective of the transaction message field, the goal of improving the transaction success rate can be achieved. Taking consumer transactions as an example, Figure 5a shows the message communication process with real-time error correction between the transaction sender, the inter-bank transfer system and the transaction receiver when the transaction request message does not meet the specifications . Figure 5b shows the message communication process with real-time error correction between the transaction sender, the inter-bank switching system and the transaction receiver when the transaction response message does not meet the specifications.

In the case of FIG. 5 a , the cross-row switching device may be configured to have the structure shown in FIG. 2 and be able to execute, for example, the flow shown in FIG. 3 . When it is detected that there are non-compliant message fields in the consumption transaction request message from the transaction sender, the inter-bank switching device sends an error correction request to the transaction sender, that is, sends an error correction request message. Correspondingly, the transaction sender can be configured to have the structure shown in FIG. 4a, and return an error correction response to the inter-bank transfer device according to the flow shown in FIG. 4b. Furthermore, the inter-bank switching device can, for example, generate an error-corrected consumption transaction request according to the flow shown in FIG. 3 and forward it to the transaction receiver. In the case that the consumption transaction response from the transaction receiver meets the specifications, the response message can be directly transferred to the transaction sender through the inter-bank transfer device without performing an error correction process.

The situation in Figure 5b is similar to that in Figure 5a, except that the inter-bank transfer device detects that the consumption transaction response message from the transaction receiver has an illegal message field, so there will be an Error correction request and response process.

In the inter-bank transfer communication process shown in Figure 5a and Figure 5b, once the inter-bank transfer device finds a non-compliant transaction at the terminal, it will not directly reject the transaction as before, but will correct the error through the error correction system. On the one hand Corrected the error information that has been confirmed and authorized by the message sender in real time. On the other hand, for errors that have not passed real-time confirmation and authorization, it can be recorded and subsequently fed back to the banking system without spending a lot of energy to frequently transform the system. In this way It can quickly improve the success rate of cross-bank transactions in a short period of time.

Above enumerated several specific embodiments to illustrate the present invention in detail, these individual examples are only for the usefulness of explaining the principle of the present invention and implementation thereof, rather than limitation of the present invention, under the situation of not departing from the spirit and scope of the present invention, Various modifications and improvements can also be made by those skilled in the art. Therefore, all equivalent technical solutions shall belong to the category of the present invention and be limited by the claims of the present invention.
