Abstract
A method for discarding a data packet includes: receiving an instruction message sent by a base station, the instruction message instructing start of monitoring transmission timeout of a data packet in an SDAP layer; when detecting that a target session is initiated, starting, according to the instruction message, a packet discarding timer corresponding to each data packet in a data stream of the target session in the SDAP layer; and when the packet discarding timer expires and it is detected that the data packet corresponding to the packet discarding timer fails to be transmitted, discarding the data packet corresponding to the packet discarding timer.
Claims8
A method for discarding a data packet, comprising:
- receiving an instruction message sent from a base station, the instruction message instructing start of monitoring transmission timeout of a data packet in a Service Data Adaptation Protocol (SDAP) layer;
- starting a packet discarding timer corresponding to each data packet in a data stream of a target session in the SDAP layer according to the instruction message, when it is detected that the target session is initiated;
- discarding the data packet corresponding to a packet discarding timer, when the packet discarding timer expires and it is detected that the data packet corresponding to the packet discarding timer fails to be transmitted;
- determining, whenever a preset period of time passed by, an identification corresponding to a discarded data packet in a current period, wherein the preset period of time is counted through a signaling timer;
- generating data packet discarding information based on the identification corresponding to the discarded data packet;
- and
- transmitting the data packet discarding information to the base station, wherein the data packet discarding information comprises the identification corresponding to the discarded data packet.
A device for discarding a data packet, comprising:
- a processor;
- and
- a memory storing instructions executable by the processor;
- wherein the processor is configured to:
- receive an instruction message transmitted from a base station, the instruction message instructing start of monitoring transmission timeout of a data packet in a Service Data Adaptation Protocol (SDAP) layer;
- start a packet discarding timer corresponding to each data packet in a data stream of a target session in the SDAP layer according to the instruction message, when it is detected that the target session is initiated;
- discard the data packet corresponding to a packet discarding timer, when the packet discarding timer expires and it is detected that the data packet corresponding to the packet discarding timer fails to be transmitted;
- determine, whenever a preset period of time passed by, an identification corresponding to a discarded data packet in a current period, wherein the preset period of time is counted through a signaling timer;
- generate data packet discarding information based on the identification corresponding to the discarded data packet;
- and
- transmit the data packet discarding information to the base station, wherein the data packet discarding information comprises the identification corresponding to the discarded data packet.
