Title
(EN) Method and device for transmitting data resources
(ZH) 数据资源传输的方法和设备
Abstract
(EN)
The embodiment of the invention provides a method and device for transmitting data resources in an IOT (internet of things) system. The method for transmitting the node data resources through fragments based on a light application layer protocol in the IOT system comprises the following steps: acquiring node data resource capacity information, wherein the resource capacity information is the capacity size of the data to be transmitted; sending a request message carrying a first fragment option to a node, wherein the first fragment option comprises recommended fragment capacity; receiving a node response message carrying a second fragment option, wherein the second fragment option comprises determined fragment capacity, and the determined fragment capacity is less than or equal to the recommended fragment capacity; and according to the determined fragment capacity and the node data resource capacity information, fragmentally transmitting the node data resources. According to the embodiment of the invention, the capacity information of the data resources of the node needing to be transmitted can be acquired, the fragment capacity used in data transmission is determined through fragmental capacity negotiation, thus the reduction of the error rate can be achieved in the process of transmission, and data can be concurrently transmitted.
