1. A Packet Data Convergence Protocol (PDCP) duplication function determination method, comprising:
receiving a PDCP duplication function configuration information sent by a network, where the PDCP duplication function configuration information is obtained by determining whether data packets associated with each priority level of data packets of a Radio Bearer (RB) are configured with a PDCP duplication function based on a number of priority levels of the data packets of the RB in a case that the RB is configured with the PDCP duplication function; and
determining, according to the PDCP duplication function configuration information, whether each data packet of the RB is configured with the PDCP duplication function;
wherein said determining whether each data packet of the RB is configured with the PDCP duplication function according to the PDCP duplication function configuration information comprises:
determining a priority level of each data packet of the RB; and
in response to the PDCP duplication function configuration information using a bitmap to indicate whether data packets associated with each priority level are configured with the PDCP duplication function, determining whether each data packet is configured with the PDCP duplication function according to the priority level of the data packet.
