Description

Data transmission method and device, and storage medium

Technical Field

The present disclosure relates to the field of wireless communication technologies, and in particular, to a data transmission method and apparatus, and a storage medium.

Background

When the functions and the performances of the dual-card dual-pass terminal equipment are evaluated under a test scene (such as main card SA + auxiliary card LTE), the fact that the terminal equipment supports concurrence of main card (NR data) + auxiliary card (VoLTE) services is found, and the concurrence/performances of the dual-card services are the same as those of the dual-card single-pass terminal equipment. But when the main card in the 5G SA data service state receives the voice calling session (VoLTE MT call) sent by the network device, the data rate drops sharply by more than 90%.
