Method and device for managing qoe of terminal in wireless communication system
The present disclosure relates to a method and device that allow a user equipment (UE) to manage quality of experience (QoE) in a wireless communication system, and an operation method of the UE managing QoE in the wireless communication system may include establishing a radio resource control (RRC) connection with a base station, transmitting UE capability information to the base station, receiving, from the base station, logged QoE measurement configuration information generated based on the UE capability information, logging QoE measurement results based on the received logged QoE measurement configuration information, reporting availability of logged QoE data to the base station, receiving a QoE data retrieval request from the base station, and transmitting logged QoE measurement result data to the base station.
1 . A method, performed by a user equipment (UE), of managing quality of experience (QoE) in a wireless communication system, the method comprising:
establishing a radio resource control (RRC) connection with a base station;
transmitting UE capability information related to logged QoE measurement to the base station;
receiving, from the base station, logged QoE measurement configuration information;
logging QoE measurement results, based on the received logged QoE measurement configuration information;
receiving a QoE data retrieval request from the base station; and
transmitting logged QoE measurement result data to the base station in response to receiving the QoE data retrieval request,
wherein the method further comprises:
camping on a new base station,
receiving new logged QoE measurement configuration information from the new base station, and
determining whether to perform logging or reporting based on the logged QoE measurement configuration information and the new logged QoE measurement configuration information.
2 . The method of claim 1 , wherein the UE is in an RRC INACTIVE mode or an RRC IDLE mode before the establishing of the RRC connection with the base station.
3 . The method of claim 1 , wherein the UE capability information comprises information indicating a capability for logged QoE measurement by the UE.
4 . The method of claim 1 , wherein the logged QoE measurement configuration information comprises at least one of trace reference information, trace collection entity (TCE) identifier (ID) information, area configuration, or logged QoE PLMN list information.
5 . The method of claim 4 , wherein the logged QoE measurement result data includes at least one of the trace reference information or TCE ID information.
6 . The method of claim 1 , wherein the logged QoE measurement configuration information is received from the base station via an RRC reconfiguration message.
7 . The method of claim 1 , further comprising:
reestablishing the RRC connection with the base station, and
reporting an availability of logged QoE data to the base station via RRC reestablishment complete message, RRC reconfiguration complete message, RRC resume complete message, or RRC setup complete message.
8 . The method of claim 1 , further comprising, before the receiving of the QoE data retrieval request from the base station, transmitting availability of logged QoE measurement results to the base station.
9 . A user equipment (UE) for managing quality of experience (QoE) in a wireless communication system, the UE comprising:
a transceiver; and
a processor coupled to the transceiver and configured to:
establish a radio resource control (RRC) connection with a base station,
transmit, via the transceiver, UE capability information related to logged QoE measurement to the base station,
receive, via the transceiver, from the base station, logged QoE measurement configuration information including at least one of trace reference information, trace collection entity (TCE) identifier (ID) information, area configuration, or logged QoE PLMN list information,
log QoE measurement results based on the received logged QoE measurement configuration information,
transmit, via the transceiver, availability of logged QoE measurement results to the base station,
receive, via the transceiver, a QoE data retrieval request from the base station, and
transmit, via the transceiver, logged QoE measurement result data to the base station,
wherein the processor is further configured to:
camp on a new base station,
receive new logged QoE measurement configuration information from the new base station, and
determine whether to perform logging or reporting based on the logged QoE measurement configuration information and the new logged QoE measurement configuration information.
