Abstract

The present invention discloses a method and a system for resending messages with a minimized number of retries and maximized timeliness of delivering the message to the receiving party. The method sets a retry period for a message that needs to be resent, determines a retry time according to the retry period, and sends the message after the retry time is reached. The retry period increases as the number of retries increases. The method and the system can ensure reliable delivery of notification messages and support many transmission protocols between different systems, does not require the receiving party to implement complicated interaction protocols to reliably receive a notification message, and is suitable for widespread use in the Internet. Moreover, the disclosure supports multiple transaction processing, can be used as a common business transaction application platform, and allows flexible expansion of multiple transactions and multiple protocols.

Claims

1. A method of message retransmission, characterized in that the method comprises:

setting a retry period for a message that needs to be resent, and determining a retry time based on the retry period, wherein the retry period increases as the number of retries performed increases; and

sending the message when the retry time is reached.

2. The method of message retransmission as recited in claim 1, characterized in that determining a retry time based on the retry period includes setting the retry time to be a current time plus the retry period.

3. The method of message retransmission as recited in claims 1 or 2, characterized in that the method further comprises:

abandoning auto-retry when the number of retries reaches or exceeds a preset value.

4. The method of message retransmission as recited in claims 1 or 2, characterized in that the method further comprises:

abandoning auto-retry when the retry period reaches or exceeds a preset value.

5. The method of message retransmission as recited in claim 1, characterized in that the retry period has a variable increment as the number of retries performed increases.

6. A system of intersystem message notification, characterized in that the system comprises:

a database, used for storing a message to be sent;

a notification executing unit, used for sending and resending the message, setting up a retry period for the message if the sending of the message fails, and updating a retry time of the message in the database based on the retry period, wherein the retry period increases as the number of retries increases; and

a notification recovering unit, used for identifying the message which has a due retry time, and triggering the notification executing unit to resend the identified message.

7. The system of intersystem message notification as recited in claim 6, characterized in that the notification recovering unit runs at set times.

8. A method of intersystem message notification, characterized in that the method comprises:

storing a notification message;

sending the stored notification message;

setting up a retry period for the notification message and determining a retry time according to the retry period if the sending of the notification message fails, wherein the retry period increases as the number of retries increases; and

resending the notification message when the retry time is reached.

9. The method of intersystem message notification as recited in claim 8, characterized in that the notification message is to be sent to an opposite end by a business application, and a failure of sending the notification message includes no return message being received from the opposite end or no message of a successful transaction being received from the opposite end.

10. The method of intersystem message notification as recited in claim 9, characterized in that sending the stored notification message comprises:

determining an address and a transmission protocol of the opposite end according to a transaction type of the notification message; and

sending the notification message to the address using the transmission protocol.

11. The method of intersystem message notification as recited in claim 9, characterized in that the resending notification message comprises:

periodically identifying notification messages that are due for retry; and

resending the identified notification messages.

12. The method of intersystem message notification as recited in claim 8, characterized in that the method further comprises:

deleting the stored notification message if the notification message is successfully sent.

13. A message resending system, characterized in that the system comprises:

a retry period unit, used for setting a retry period for a message to be resent, wherein the retry period increases as the number of retries increases;

a retry time unit, used for determining a retry time according to the retry period; and

a sending unit, used for sending the message after the retry time is reached.

14. The message resending system as recited in claim 13, characterized in that the system further comprises:

a retry termination unit, used for terminating resending of the message if the number of retries is greater than or equal to a preset value or if the retry period is greater than or equal to a preset value.

15. The message resending system as recited in claim 13, characterized in that an increment of the retry period changes as the number of retries performed increases.
