Performance Evaluation of Multi-Access Based on ATSSS Rules

Abstract

5th generation mobile communication technology (5G) uses its extended capability, access traffic steering, switching, and splitting (ATSSS) to enable multipath transmission of data, which is currently being standardized. Attempts are being made in both academia and industry to study multi-access technologies based on the ATSSS function. This study follows the tenet of minimal modification of the existing 5G protocol data unit session management and builds a multi-access network architecture to achieve multi-path transmission of data. The results reveal that multi-access technology can significantly improve the average throughput of users and network load balancing.
