Abstract
A data unit transmission method includes: determining data to be transmitted by a PDU (Packet Data Unit) of a data bearer; and determining whether the data to be transmitted is an entire SDU (Service Data Unit) in an RLC (Radio Link Control) UM (Unacknowledged Mode) or a data segment of the SDU in the RLC UM; if the data is a data segment of the SDU, obtaining a PDU of the data bearer and adding a SN (Serial Number) field, indicating that the data correspond to a header of the PDU.
Claims13
A data unit transmission method, comprising:
- determining data to be transmitted by a PDU (Packet Data Unit) of a data bearer;
- determining whether the data to be transmitted is an entire SDU (Service Data Unit) in an RLC (Radio Link Control) UM (Unacknowledged Mode) or a data segment of the SDU in the RLC UM;
- if the data is a data segment of the SDU, obtaining the PDU of the data bearer and adding an SN (Serial Number) field, indicating that the data correspond to a header of the PDU, and
- receiving a configuration instruction for the data bearer, wherein the configuration instruction is configured to instruct to turn off an ROHC (Robust Header Compression) function of a data bearer in the RLC UM.
A data unit transmission device comprising:
- a processor;
- and
- a memory configured to store an executable instruction of the processor, wherein the processor is configured to:
- determine data to be transmitted by a PDU (Packet Data Unit) of a data bearer;
- determine whether the data to be transmitted is an entire SDU (Service Data Unit) in an RLC (Radio Link Control) UM (Unacknowledged Mode) or a data segment of the SDU in the RLC UM;
- if the data is a data segment of the SDU, obtaining a PDU of the data bearer with adding a SN (Serial Number) field, indicating that the data correspond to a header of the PDU, and
- receive a configuration instruction for the data bearer, wherein the configuration instruction is configured to instruct to turn off an ROHC (Robust Header Compression) function of the data bearer in the RLC UM.
A data unit transmission device comprising:
- a processor;
- and
- a memory configured to store executable instructions for the processor, wherein the processor is configured to:
- obtain a specific field of a PDU (Packet Data Unit), wherein the specific field is configured to indicate whether the PDU comprises a data segment of an SDU (Service Data Unit);
- if the specific field indicates that the PDU comprises an entire SDU, obtain the SDU from the PDU;
- if the specific field indicates that the PDU comprises a data segment of an SDU, continuously receive PDUs until all the PDUs with the same SN (Serial Number) field are received;
- and reordering all the PDUs with the same SN field to obtain an entire SDU, and
- receive a configuration instruction for a data bearer, wherein the configuration instruction is configured to instruct to turn off an ROHC (Robust Header Compression) function of the data bearer in the RLC UM.
