Claim 11:
12. A Packet Data Convergence Protocol (PDCP) duplication function activation method, comprising:
determining a PDCP duplication function activation signaling, wherein the PDCP duplication function activation signaling comprises at least one data offload indication identifier of at least one radio bearer configured with a PDCP duplication function; and
transmitting the PDCP duplication function activation signaling to a User Equipment (UE), so that the UE determines a duplication number of a data packet of the at least one radio bearer based on the PDCP duplication function activation signaling;
wherein the PDCP duplication function activation signaling further comprises indication information,
wherein said the UE determining a duplication number of a data packet of the at least one radio bearer based on the PDCP duplication function activation signaling comprises:
based on that the at least one data offload indication identifier indicates that the at least one radio bearer is allowed to perform data offload, determining whether a data amount of the data packet is greater than or equal to a preset offload threshold;
in response to the data amount of the data packet being greater than or equal to the preset offload threshold, dividing the data packet into a first data packet and a second data packet, and determining a number of first logical channels used by the at least one radio bearer and a number of second logical channels used by the at least one radio bearer based on the indication information, to obtain a duplication number of the first data packet and a duplication number of the second data packet; and
in response to the data amount of the data packet being less than the preset offload threshold, determining a number of third logical channels used by the at least one radio bearer based on the indication information, to obtain the duplication number of the data packet,
wherein the first data packet refers to a data packet transmitted through a master node, the second data packet refers to a data packet transmitted through a secondary node, the first logical channels belong to the master node, the second logical channels belong to the secondary node, and the third logical channels belong to the master node.
