An embodiment of the present application provides a data transmission method, as shown in fig. 2, including:
step 101: when transmitting specific data, the terminal changes the transmission priority of the specific data and/or specific control signaling.
In the embodiment of the application, when sending the specific data, the terminal may change the sending priority of the specific data and/or the specific control signaling, so that when the terminal sends the uplink data in a direct data sending manner, the sending priority of the data may be increased and/or the sending priority of the specific control signaling may be decreased, and the data is preferentially sent to the network side device, thereby increasing the success rate of data sending.
In this embodiment, sending the specific data may refer to sending the specific data by a terminal in an idle (idle) state or an inactive (inactive) state.
It should be noted that the data may be uplink data transmitted by using a direct data transmission method, or may be uplink data transmitted by using another method. When there is data to be sent, the terminal may change the sending priority of the data and/or the specific control signaling according to the configuration of the network side device or the protocol convention, so as to ensure the sending success rate of the data or the specific control signaling.
It should be noted that, when the UE is in an idle (idle) state or an inactive (inactive) state, the UE may directly send data to the network side in the following manner:
(1) msg3 for a 4-step random access procedure for initial access;
(2) MsgA of 2-step random access process of initial access;
(3) dedicated Physical Uplink Shared Channel (PUSCH) resources configured by a network side device include a pre-configured PUSCH; or, pre-allocated Uplink Resource (PUR).
In addition, the network side can directly send data to the UE by:
(1) msg4 for a 4-step random access procedure for initial access;
(2) MsgB of 2-step random access process of initial access;
(3) and the network side equipment configures downlink feedback resources corresponding to the dedicated uplink resources.
Before transmitting data, the terminal may receive reserved configuration context indication information sent by the network side device, where the indication information indicates that the UE reserves its context configuration, such as a Data Radio Bearer (DRB) configuration and a security configuration. The context is configured for the UE to resume connection and/or resume data transceiving use. For example, the network side device sends suspension (suspend) indication information in a Radio Resource Control (RRC) Release (Release) message, and may use the context configuration for UE connection resumption and/or data transmission/reception resumption when releasing a connected (connected) UE to an idle state and/or an inactive state.

In a specific example, the network side device configures DRB-1 to adopt a direct data transmission mode, and when DRB-1 has data to transmit, the UE changes the transmission priority of the DRB-1 data and the specific control signaling.
In some embodiments, the direct data transmission comprises at least one of:
transmitting data in Msg3 by using a 4-step random access process;
transmitting data in MsgA in the 2-step random access process;
and sending data in the dedicated Physical Uplink Shared Channel (PUSCH) resource configured by the network side equipment.
In some embodiments, the bearer indication using direct data transmission includes at least one of:
adopting a direct data transmission bearing type;
and direct data transmission bearer identification is adopted.

In some embodiments, the bearer identification using direct data transmission includes at least one of:
DRB identification;
quality of service flow (QoS flow) identification;
