  • Publication number: 20210084129
    Abstract: A method of processing data includes: receiving, by a Packet Data Convergence Protocol (PDCP) layer, a PDCP Service Data Unit (SDU) from an upper layer; and deleting the PDCP SDU and a PDCP Packet Data Unit (PDU) corresponding to the PDCP SDU upon determining that a discard timer corresponding to the PDCP SDU is not expired and a preset condition is satisfied. The PDCP SDU is mapped to an Unacknowledged Mode (UM) or a Transparent Mode (TM) of a Radio Link Control (RLC) layer. Thus, the PDCP SDU will not reside in a UE cache, thereby reducing cache space occupied by the PDCP SDU.

  • Publication number: 20200404527
    Abstract: The present disclosure relates to an information recording method. The method is applicable to user equipment, and includes: receiving indication information from a base station, wherein the indication information includes mode indication information indicating a mode for recording Minimized Driving Test (MDT) information; and when the user equipment is in an inactive state, recording the MDT information according to the mode indication information. According to examples of the present disclosure, the user equipment may record the MDT information when it is in the inactive state, such that the user equipment transmits the MDT information recorded in the inactive state to the base station when the user equipment establishes or restores a communication connection with the base station later. Thus, the base station can determine various failures of the user equipment in the inactive state, thereby facilitating the base station to perform troubleshooting accurately.
