Machine-to-machine (M2M)-platform-based message sequential transmission and receiving method and device

Abstract

The invention discloses a machine-to-machine (M2M)-platform-based message sequential transmission and receiving method and an M2M-platform-based message sequential transmission and receiving device. The method comprises the following steps of: when an M2M platform judges interface message transmitted by terminal equipment or an application platform is transparent transmission messages, receiving the transparent transmission messages from the terminal equipment or the application platform; numbering the transparent transmission messages according to a receiving sequence; and transmitting the transparent transmission messages received from the terminal equipment to the application platform according to sequence numbers, or transmitting the transparent transmission messages received from the application platform to the terminal equipment. The device numbers the transparent transmission messages, and sequentially transmits the transparent transmission messages in a sliding window way to improve the transmission efficiency, reliability and the like of transparent transmission messages in the M2M platform.

Description

technical field [0001] The present invention relates to the field of message processing on an M2M platform, in particular to a method and device for orderly sending and receiving messages based on an M2M platform. Background technique [0002] refer to figure 1 , which is a network diagram of an M2M (Machine-to-Machine, machine-to-machine communication technology) platform in the prior art. The M2M platform includes a WEB portal module 51, a service processing module 52, a terminal interface submodule 53, an application interface submodule 54, and the like. The M2M platform communicates with the terminal device 60 through the terminal interface sub-module 53, and can deploy multiple terminal interface sub-modules 53 to share the load when the number of terminal devices 60 is huge. The M2M platform also communicates with the application platform 70 through the application interface sub-module 54 , and similarly, the number of the application interface sub-module 54 can also...

AI Technical Summary

Problems solved by technology

[0006] There are obvious limitations and deficiencies in the above data transmission methods:

In addition, at present, the terminal device 60 can access the M2M platform in multiple ways at the same time. If a data transparent transmission message is sent in two different access ways, the M2M platform may also forward the message. The case of the application platform 70

[0008] 2. The real-time and reliability of the message cannot be guaranteed

Since the business flow data between the terminal device 60 and the application platform 70 is not processed by a separate module, the transparent transmission message received by the terminal interface sub-module 53 and the application interface sub-module 54 and other messages are handed over to the business processing module 52 for processing. Messages and other messages have the same processing priority on the M2M platform. If there are too many messages on the platform, the forwarding time of transparently transmitted messages will be affected, and even packet loss will occur.

[0009] 3. Under the existing subcontracted message sending and receiving mechanism between the terminal device 60 and the M2M platform, the message sending and receiving speed between the terminal device 60 and the application platform 70 is relatively slow
