Problems solved by technology

[0003] However, under the 5G system, when integrating with the TSN network, this method can only be used as a reference and reference. In reality, there are some disadvantages, such as how to eliminate the terminal's uncertainty about the two independent clocks that receive the 5G clock and the TSN clock. How to eliminate the problem of resource waste due to the mismatch between business formats and non-scheduling resources; how to eliminate the error accumulation caused by the difference in the granularity of basic events, resulting in the mismatch between service sending time and non-scheduling resources

Abstract

The invention provides a 5G-TSN cross-domain QoS and resource mapping method and device and a computer readable storage medium. The method comprises the following steps: establishing a Markov-based 5G-TSN resource mapping conversion relation model according to arrival rates and service rates of service flows and data packets, and constructing a 5G-TSN system state conversion balance equation according to corresponding transition probability matrix constraint conditions; and completing a network operation state conversion process of service flow QoS resource mapping of the 5G-TSN system in a framework of the balance equation. According to the method, the association relationship between the TSN time slot and the 5G resource block required for bearing the service association data message is researched aiming at the resource characteristic difference of the 5G and the TSN in the physical layer, so that bidirectional mapping of different QoS service characteristics of the heterogeneous network is realized, and rapid data conversion and scheduling are facilitated.

Description

technical field [0001] This application relates to the technical field of collaborative integration of 5G and the industrial Internet, and specifically relates to a 5G-TSN cross-domain QoS and resource mapping method, device, and computer-readable storage medium. Background technique [0002] The DSP implementation scheme applicable to the mapping of distributed virtual resource blocks to physical resource blocks in LTE systems includes: a numbering step, numbering the physical resource blocks of the current system bandwidth, and correspondingly numbering the same number of virtual resource blocks, wherein the physical The number of resource blocks and virtual resource blocks is N PRB ;Matrix generation step, generate ceil(N / N d )×N d Dimensional first matrix, N d is the number of PRBs to which a DVRB is mapped; the matrix mapping step reads elements from the first matrix in a predetermined manner, and writes the read elements into ceil(N / N d )×N d Dimensional second ma...
