Communication method and access network device

A communication method, comprising:

• receiving, by a second access network device, a first message from a first access network device, wherein the first message carries a first quality of service (QoS) flow identification (QFI) for a split bearer corresponding to the first access network device and a first QoS parameter corresponding to the first QFI;
• in response to receiving the first message from the first access network device, performing, by the second access network device, data transmission based on a priority of the first QFI, the priority of the first QFI being determined based on the first QFI and the first QoS parameter;
• and
• sending, by the second access network device, a second message to the first access network device, wherein the second message is a response to the first message, and the second message comprising a second QFI for a split bearer corresponding to the second access network device and a second QoS parameter corresponding to the second QFI.

An apparatus, comprising:

• at least one processor;
• and
• a memory storing instructions executable by the at least one processor, wherein the instructions, when executed by the at least one processor, instruct the at least one processor to perform the following operations:
• sending a first message to a second access network device, wherein the first message carries a first quality of service (QoS) flow identification (QFI) for a split bearer corresponding to a first access network device and a first QoS parameter corresponding to the first QFI;
• receiving a second message from the second access network device, wherein the second message is a response to the first message, wherein the second message carries a second QFI for a split bearer corresponding to the second access network device and a second QoS parameter corresponding to the second QFI;
• and
• in response to receiving the second message from the second access network device, performing data transmission based on a priority of the second QFI, the priority of the second QFI being determined based on the second QFI and the second QoS parameter.
