Implementation of a segmented delimitation and positioning method for VOLTE end-to-end voice quality problems based on the routing set

In this paper, using VOLTE DPI data resources (S1U interface data), through the study of service characteristics and data correlation, according to the service we construct a routing set based on network topology. By taking the base station as the tree root, we establish a poor quality tree from the base station to the EPC core network, and then to the IMS core network. For the single interface s1u data we accurately realize the segmented delimitation of end-to-end voice quality problems of VOLTE by calculating the voice quality of VOLTE for all routing sets and using the sample space replacement algorithm for comparison. In this paper, the segmented delimitation method based on the single interface data of s1u is Implemented, which can greatly reduce the acquisition cost and storage resource consumption, and can effectively realize the function of segmented delimitation and positioning for the end-to-end voice quality problems of VOLTE.
