Abstract

The invention provides a data transmission method and device, and a storage medium, and relates to the technical field of wireless communication. And when a first user card of the terminal equipment receives voice paging information sent by network equipment, the terminal equipment sends network switching rejection information to the network equipment to indicate the network equipment to reject switching from the 5G network to the 4G network, and in response to the network switching rejection information, the network equipment sends a voice paging request corresponding to the voice paging information to the second user card of the terminal equipment and establishes connection with the second user card of the terminal equipment to perform a voice session, so that the main card is prevented from falling back to 4G, the SA + LTE service concurrence of the main card is realized, the data performance is effectively guaranteed, and the user experience is improved. And meanwhile, the user perception of the bi-pass terminal equipment is greatly improved.

Description

technical field [0001] The present disclosure relates to the technical field of wireless communication, and in particular, to a data transmission method and device, and a storage medium. Background technique [0002] When evaluating the function and performance of a dual-card dual-pass terminal device in a test scenario (such as main card SA+secondary card LTE), it is found that the terminal device supports concurrent main card (NR data) + secondary card (VoLTE) services, and the dual-card business concurrent function / The performance is the same as that of the dual-card single-pass terminal equipment. However, when the main card in the 5G SA data service state receives a voice calling session (VoLTE MT call) sent by the network device, the data rate drops sharply by more than 90%. [0003] After analysis, the reason is that the current 5G SA network mainly falls back to the 4G VoLTE network through EPS Fallback to provide voice services, resulting in the SA data service of...
