Transmission Rate Control Method And Apparatus

A transmission rate control method, comprising:

• obtaining, by a master base station, a user equipment (UE) aggregate maximum bit rate (UE-AMBR);
• determining, by the master base station, a bearer type of a secondary base station;
• determining, based on the UE-AMBR, a second UE-AMBR used for the secondary base station, wherein the second UE-AMBR is used by the secondary base station to control a terminal transmission rate based on the bearer type of the secondary base station;
• and
• sending, by the master base station, the second UE-AMBR and the bearer type of the secondary base station to the secondary base station.

A communications apparatus, comprising:

• at least one processor;
• and
• a memory, wherein the memory is configured to store instructions executable by the at least one processor, wherein the instructions, when executed by the at least one processor, instruct a secondary base station to perform the following opetations:
• receiving a second user equipment (UE) aggregate maximum bit rate (UE-AMBR) and a bearer type of the secondary base station from a master base station, wherein the second UE-AMBR is determined according to a UE-AMBR received from a core-network;
• and
• controlling a terminal transmission rate based on the second UE-AMBR and the bearer type of the secondary base station.

A communication apparatus, comprising:

• at least one processor;
• and
• a memory, wherein the memory is configured to store instructions executable by the at least one processor, wherein the instructions, when executed by the at least one processor, instruct a secondary base station to perform the following operations:
• obtaining a user equipment (UE) aggregate maximum bit rate (UE-AMBR);
• determining a bearer type of a secondary base station;
• determining, based on the UE-AMBR, a second UE-AMBR used for the secondary base station, wherein the second UE-AMBR is used by the secondary base station to control a terminal transmission rate based on the bearer type of the secondary base station;
• and
• sending the second UE-AMBR and the bearer type of the secondary base station to the secondary base station.
