    摘要: An example security processing method includes receiving data packets at a packet data convergence protocol (PDCP) layer from an upper layer and parsing header information of each of the data packets to determine a length of each of the plurality of headers within the corresponding header information and whether a security header is present or absent in the corresponding data packets. The method further includes identifying corresponding header information of the data packets in which the security header is present based on the determination. The method further includes encrypting, based on the determined header lengths, only each of the plurality of headers of the identified corresponding header information in which the security header is present, and thereafter transmitting the one or more data packets to a lower layer after adding information regarding each of the encrypted headers along with their encryption length into a PDCP header.

    摘要: The present disclosure relates to a 5G communication system or a 6G communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE). A method for handling segmentation in a converged layer 2 (L2) communication network is provided. The method includes assigning, by a converged L2 of a transmitter, a L2 sequence number (SN) to a protocol data unit (PDU). The L2 SN includes at least one of a last segment indication (LSI) indicating a presence of a last service data units (SDU) of the complete PDU, a length indicator exist (LIE) indicating a presence of a length indicator (LI) after a L2 header, or a SI indicating a segmentation status or stage of the complete PDU, receiving, by a medium access control (MAC) layer of the transmitter, a grant opportunity or a transmission opportunity for transferring the PDU available at the converged L2, and sending the PDU to a lower layer of the transmitter for transmission to a receiver with or without segmentation based on the grant or a transmission opportunity.

    摘要: A method and an apparatus for clustering Internet protocol (IP) packets in a wireless network are provided. The method includes receiving, by a network device in the wireless network, a plurality of IP packets from an upper layer of a user equipment (UE) in the wireless network or vice versa, initiating a timer on receiving the plurality of IP packets from the upper layer, forming a cluster of IP packets having a predetermined maximum size while the timer is running, stopping the timer once the formation of the cluster is completed, and transmitting the cluster of IP packets to a lower layer of the UE, where the lower layer treats the cluster of IP packets as a single payload to minimize the IP packets handled at the lower layer of the UE.
