1. A method, comprising:
receiving, by a terminal-side device, first indication information from a first network-side device, wherein the first indication information triggers reestablishment of a first packet data convergence protocol (PDCP) entity of the terminal-side device;
receiving, by the terminal-side device, third indication information from the first network-side device, wherein the third indication information indicates that a first bearer corresponding to the first PDCP entity is used other than to perform duplication transmission between the terminal-side device and a core network-side device; and
when the first bearer corresponding to the first PDCP entity is used other than to perform duplication transmission between the terminal-side device and the core network-side device, in a process in which the terminal-side device reestablishes the first PDCP entity, setting a parameter of the first PDCP entity to an initial value; and
wherein the parameter of the first PDCP comprises at least one of: a first parameter, a second parameter, or a third parameter; and
wherein the first parameter indicates a serial number or a count value of a next PDCP service data unit (SDU) that the first PDCP entity expects to receive, the second parameter indicates a serial number or a count value of a next PDCP SDU to be sent by the first PDCP entity, and the third parameter indicates a serial number or a count value of a 1st PDCP SDU that is not delivered by the first PDCP entity to an upper layer.
