This application relates to the field of communication technology, and discloses a time delay acquisition method and device, optimization method and device, which are used to solve the problem that the time delay in the data transmission process cannot be optimized in the prior art because the test cannot be segmented question. The delay obtaining method includes: the first device sends a request message to the second device, the request message is used to obtain the delay data of the sub-transmission path between the second device and the third device, and the third device and the second device can directly Establish a transmission path; the first device receives a response message sent by the second device, and the response message includes the delay data of the sub-transmission path between the second device and the third device; the first device saves the corresponding relationship between the sub-transmission path and the delay data , wherein the sub-transmission path is represented based on the device identity group formed by the identity of the second device and the identity of the third device. The present application respectively obtains delay data between devices that can directly establish a transmission path, and realizes segmental acquisition of delay data.
Description
technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular, to a delay acquisition method and device, and an optimization method and device. Background technique [0002] At present, businesses such as mobile Internet, Internet of Things, autonomous driving, and telemedicine are developing rapidly. In order to meet the new requirements and features of these networks, the fifth-generation mobile communication (5G) has become a research and development hotspot in the global communication industry. Typical scenarios in 5G One: Ultra reliable low latency communication (URLLC) is a research and development challenge. How to ensure millisecond-level E2E latency during end-to-end (E2E) data transmission is The key problem that 5G needs to solve is also one of the main characteristics that distinguish 5G from 4G. [0003] Figure 1A The composition of the total delay from the terminal to the application (AP...
