Abstract
A data transmission method comprises: determining whether a switched target Data Radio Bearer (DRB) supports sequential data transmission or not, when a DRB remapping event is detected during a data transmission process of a target data stream; in case that transmitting, through an original DRB, data packets in the target data stream that have been delivered to the original DRB, and transmitting, through the target DRB, data packets in the target data stream that have not been delivered to the original DRB, in case that the target DRB does not support sequential data transmission; and in case that transmitting data packets in the target data stream in a transmission mode in which sequence of data packets is not changed, in case that the target DRB supports sequential data transmission.
Claims20
A data transmission method, comprising:
- determining whether a switched target Data Radio Bearer (DRB) supports sequential data transmission or not, when a DRB remapping event is detected during a data transmission process of a target data stream;
- transmitting data packets in the target data stream that have been delivered to the original DRB through an original DRB, and transmitting data packets in the target data stream that have not been delivered to the original DRB through the target DRB, in case that the target DRB does not support sequential data transmission;
- and
- transmitting data packets in the target data stream in a transmission mode in which sequence of data packets is not changed, in case that the target DRB supports sequential data transmission.
A terminal, comprising at least one processor and a memory that stores at least one instruction, at least one program, a code set or an instruction set thereon, wherein the at least one instruction, the at least one program, the code set or the instruction set is loaded and executed by the processor to implement following steps:
- determining whether a switched target Data Radio Bearer (DRB) supports sequential data transmission or not, when a DRB remapping event is detected during a data transmission process of a target data stream;
- transmitting data packets, in the target data stream, that have been delivered to the original DRB through an original DRB, and transmitting data packets, in the target data stream, that have not been delivered to the original DRB through the target DRB, in case that the target DRB does not support sequential data transmission;
- and
- transmitting data packets, in the target data stream in a transmission mode in which sequence of data packets is not changed, in case that the target DRB supports sequential data transmission.
A non-transitory computer readable storage medium, wherein at least one instruction, at least one program, a code set or an instruction set is stored in the storage medium, and is loaded and executed by at least one processor to implement following steps:
- determining whether a switched target Data Radio Bearer (DRB) supports sequential data transmission or not, when a DRB remapping event is detected during a data transmission process of a target data stream;
- transmitting data packets, in the target data stream, that have been delivered to the original DRB through an original DRB, and transmitting data packets, in the target data stream, that have not been delivered to the original DRB through the target DRB, in case that the target DRB does not support sequential data transmission;
- and
- transmitting data packets in the target data stream in a transmission mode in which sequence of data packets is not changed, in case that the target DRB supports sequential data transmission.
