1. A data processing method, comprising:
determining, by a first device, to change a type of at least one radio bearer of the first device from a first type to a second type; and
receiving, by the first device, first indication information transmitted by a second device, wherein the first indication information is used to indicate that a radio bearer type of data that is of the at least one radio bearer and is received by the first device is a first-type radio bearer or a second-type radio bearer;
wherein the first indication information comprises an RLC sequence number, and the RLC sequence number is a sequence number of an RLC protocol data unit of the at least one radio bearer,
wherein the RLC protocol data unit is a last RLC protocol data unit comprising an RLC service data unit encapsulated based on a format of the first-type radio bearer, or the RLC protocol data unit is a first RLC protocol data unit comprising an RLC service data unit encapsulated based on a format of the second-type radio bearer, and
wherein the first device is a terminal device, and the second device is a base station; or the first device is a base station, and the second device is a terminal device.
