US 2022/0286933 A1 · METHOD FOR CELL RESELECTION IN IDLE MODE FOR NEXT GENERATION MOBILE COMMUNICATION SYSTEMS

Abstract

The present disclosure relates to a communication technique of fusing a 5G communication system for supporting higher data transmission rate beyond a 4G system with an IoT technology and a system thereof. The present disclosure may be applied to intelligent services (e.g., smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, security and safety related service, or the like) based on the 5G communication technology and the IoT related technology. A communication method of a base station, the method comprising: establishing at least one bearer with a terminal; receiving a downlink packet being transmitted to the terminal; determining a bearer mapped to quality of service (QoS) information of the downlink packet; and transmitting, to the terminal, the downlink packet through the determined bearer.

Dependent claims

A method performed by a base station in a wireless communication system, the method comprising:

receiving, from a next generation core network (NGCN), a downlink (DL) packet including information for identifying a quality of service (QoS) based on a flow;
identifying whether a data radio bearer (DRB) to which to map the flow exists among established at least one DRB, wherein the flow to the DRB mapping is based on the information for identifying the QoS based on the flow;
in case that the DRB to which to map the flow does not exist among the established at least one DRB, establishing the DRB;
transmitting, to a terminal, the DL packet over the DRB, the DL packet including the information for identifying the QoS based on the flow and an indication associated with a reflective QoS;
and
receiving, from the terminal, an uplink (UL) packet over the DRB, the UL packet being associated with the flow.

A base station in a wireless communication system, the base station comprising:

a transceiver;
and
a controller coupled with the transceiver and configured to:
receive, from a next generation core network (NGCN), a downlink (DL) packet including information for identifying a quality of service (QoS) based on a flow,
identify whether a data radio bearer (DRB) to which to map the flow exists among established at least one DRB, wherein the flow to the DRB mapping is based on the information for identifying the QoS based on the flow,
in case that the DRB to which to map the flow does not exist among the established at least one DRB, establish the DRB,
transmit, to a terminal, the DL packet over the DRB, the DL packet including the information for identifying the QoS based on the flow and an indication associated with a reflective QoS, and
receive, from the terminal, an uplink (UL) packet over the DRB, the UL packet being associated with the flow.

5 more elements

A terminal in a wireless communication system, the terminal comprising:

a transceiver;
and
a controller coupled with the transceiver and configured to:
establish a DRB to which to map a flow associated with a downlink (DL) packet, in case that the DRB to which to map the flow associated with the DL packet does not exist among established at least one DRB, wherein the flow to the DRB mapping is based on information for identifying a quality of service (QoS) based on the flow,
receive, from a base station, the DL packet over the DRB, the DL packet including the information for identifying the QoS based on the flow and an indication associated with a reflective QoS, and
transmit, to the base station, an uplink (UL) packet over the DRB, the UL packet being associated with the flow.
