Title: Data packet deletion method, device, and storage medium
Inventor: FU ZHE
IPC: H04L12/851
Filed: 2019-08-16
Abstract: A data packet deletion method, a device, and a storage medium. The method comprises: when a protocol layer entity of a sending end receives an SDU from a high layer, determine a QoS flow to which the SDU belongs; when the QoS flow to which the SDU belongs is a first QoS flow, the protocol layer entity starts a first discard timer, or the protocol layer entity selects a reference timer from the first discard timer and a second discard timer (a discard timer of DRB granularity), and starts the reference timer; when the first discard timer has time out, or the reference timer has time out, the protocol layer entity deletes the SDU and a PDU corresponding to the SDU. By defining, for a protocol layer, a first discard timer of smaller granularity: a first discard timer of QoS flow granularity, a data packet can be deleted according to a QoS flow characteristic of a service, the requirements for deletion of the data packet for QoS flows having different features can be satisfied while the requirement for saving a storage space of the sending end is satisfied. Moreover, when the first discard timer and the second discard timer exist simultaneously, a specific behavior of the sending end is defined, so as to avoid the uncertainty of the behavior of the sending end when two discard timers exist.
