Method and system for managing quality of service in wireless communications system

A method for managing quality of service in a wireless communications system, the method comprising:

• receiving, by a radio access network device through p bearers between a user equipment and the radio access network device, service data from the user equipment to a packet data network (PDN) network, wherein p is an integer greater than or equal to 1;
• performing, by the radio access network device, flow demapping of data of the p bearers according to a quality of service (QoS) rule, to obtain the service data;
• and
• transmitting, by the radio access network device, the service data to a core network device.

A radio access network device, comprising:

• a communications interface, configured to receive service data transmitted by a core network device from a packet data network (PDN) network to a user equipment;
• and
• a processor, configured to map the service data to t bearers between the radio access network device and the user equipment according to a quality of service (QoS) rule, wherein t is an integer greater than or equal to 1, wherein
• the communications interface is further configured to transmit the service data mapped to the t bearers to the user equipment.
