1. A bearer control method, applied to a terminal, wherein a target radio bearer RB corresponding to the terminal is configured with a data duplication function, the target RB is configured with N transmission paths, N is an integer greater than 2, and the method comprises:
receiving an indication message sent by a network side device, wherein the indication message is used to indicate to activate or deactivate duplication-function, of the transmission path of the target RB; and
determining an available transmission path of the target RB according to the indication message;
wherein the indication message comprises second MAC CE signaling, wherein the second MAC CE signaling is used to indicate to activate or deactivate duplication function of the transmission path of the target RB;
wherein the second MAC CE signaling comprises: a first field used to identify the target RB, and a second field used to indicate a status of a transmission path whose sequence number is i among the N transmission paths of the target RB;
wherein i is an integer greater than or equal to 0 and less than or equal to N;
wherein the determining an available transmission path of the target RB according to the indication message comprises:
sending, by a MAC entity in the terminal, indication information to a PDCP entity corresponding to the target RB, wherein the indication information is determined according to the second MAC CE signaling; and
determining, by the PDCP entity, the available transmission path of the target RB according to the indication information;
wherein the indication information comprises: m transmission paths in a deactivated state and/or n transmission paths in an activated state, m and n are positive integers, m+n≤N, and the m transmission paths in the deactivated state and/or the n transmission paths in the activated state are determined according to the second MAC CE signaling; and
the determining, by the PDCP entity, the available transmission path of the target RB according to the indication information comprises:
when the indication information comprises the n transmission paths in the activated state, determining the n transmission paths in the activated state as the available transmission path of the target RB; or
when the indication information comprises only the m transmission paths in the deactivated state, determining a transmission path among the N transmission paths of the target RB other than the m transmission paths in the deactivated state as the available transmission path.
