Abstract
The present disclosure provides a data transmission method, related devices and system. The method includes: an upper layer transmits a data packet to a corresponding Service Data Adaptation Protocol (SDAP) entity, according to at least one of a network slice identifier, an SDAP identifier, a flow identifier or a session identifier; the SDAP entity adds the flow identifier to the data packet, and transmits the data packet with the flow identifier to a Packet Data Convergence Protocol (PDCP) entity corresponding to a Data Radio Bearer (DRB), according to a corresponding relationship between the SDAP entity and the DRB.
Claims16
A data receiving end, comprising:
- a processor, a memory, a network interface and a user interface, wherein the processor, the memory, the network interface and the user interface are coupled through a bus system, the processor is configured to read a program from the memory to perform:
- receiving, by a Packet Data Convergence Protocol (PDCP) entity, a data packet from a data transmitting end, and transmitting the data packet to a corresponding Service Data Adaptation Protocol (SDAP) entity according to a flow identifier carried by the data packet;
- and,
- forwarding, by the SDAP entity, the data packet to an application protocol layer, or forwarding the data packet to a corresponding network slice, a flow and a Protocol Data Unit (PDU) session;
- wherein the processor is further configured to read the program from the memory to perform:
- establishing the SDAP entity in advance, according to configuration information which is configured by a network or protocol-agreed;
- wherein the configuration information comprises at least one of a network slice identifier, a Data Radio Bearer (DRB) identifier, the flow identifier, a session identifier, or association relationship indication information;
- wherein the association relationship indication information comprises any one of:
- indicating that one SDAP entity corresponds to one flow;
- indicating that one SDAP entity corresponds to one PDU session;
- indicating that one SDAP entity corresponds to one PDCP entity;
- indicating that one SDAP entity corresponds to one Medium Access Control (MAC) entity;
- indicating that one SDAP entity corresponds to one terminal.

A computer readable storage medium, which stores a data transmission program, wherein when the data transmission program is executed by a processor, the processor is caused to perform:
- receiving, by a Packet Data Convergence Protocol (PDCP) entity, a data packet from a data transmitting end, and transmitting the data packet to a corresponding Service Data Adaptation Protocol (SDAP) entity according to a flow identifier carried by the data packet;
- and,
- forwarding, by the SDAP entity, the data packet to an application protocol layer, or forwarding the data packet to a corresponding network slice, a flow and a Protocol Data Unit (PDU) session;
- wherein when the data transmission program is executed by the processor, the processor is further caused to perform:
- establishing the SDAP entity in advance, according to configuration information which is configured by a network or protocol-agreed;
- wherein the configuration information comprises at least one of a network slice identifier, a Data Radio Bearer (DRB) identifier, the flow identifier, a session identifier, or association relationship indication information;
- wherein the association relationship indication information comprises any one of:
- indicating that one SDAP entity corresponds to one flow;
- indicating that one SDAP entity corresponds to one PDU session;
- indicating that one SDAP entity corresponds to one PDCP entity;
- indicating that one SDAP entity corresponds to one Medium Access Control (MAC) entity;
- indicating that one SDAP entity corresponds to one terminal.

A computer readable storage medium, which stores a data transmission program, wherein when the data transmission program is executed by a processor, the processor is caused to perform:
- transmitting, by an upper layer, a data packet to a corresponding Service Data Adaptation Protocol (SDAP) entity, according to at least one of a network slice identifier, an SDAP identifier, a flow identifier or a session identifier;
- adding, by the SDAP entity, a flow identifier corresponding to the data packet, to the data packet;
- and,
- transmitting the data packet with the flow identifier to a Packet Data Convergence Protocol (PDCP) entity corresponding to a Data Radio Bearer (DRB), according to a corresponding relationship between the SDAP entity and the DRB;
- wherein before transmitting, by the upper layer, the data packet to the corresponding SDAP entity, according to at least one of the network slice identifier, the flow identifier or the session identifier, the processor is caused to perform:
- establishing the SDAP entity in advance, according to configuration information which is configured by a network or pre-defined;
- wherein the configuration information comprises at least one of the network slice identifier, a DRB identifier, the flow identifier, the session identifier, or association relationship indication information;
- wherein the association relationship indication information comprises any one of:
- indicating that one SDAP entity corresponds to one flow;
