## Abstract

A Method and Apparatus for application layer measurement reporting in RRC_INACTIVE is provided. The method includes receiving an RRC reconfiguration message from the first base station containing the first other configuration1 and the other configuration2, receiving from the first base station an RRC release message containing a suspend configuration and a first terminal identifier and a second terminal identifier, storing the application layer measurement configurations included in said first other configuration1, monitoring paging based on said suspend configuration, receiving a paging message containing said first terminal identifier, releasing said other configuration2, transmitting an RRC resume request message containing said second terminal identifier to the second base station, receiving an RRC resume message containing the second other configuration1 from the second base station, and releasing the application layer measurement configuration indicated in said second other configuration1.

## Claims

### Claim 1

A method performed by a terminal, the method comprising:
transmitting, by the terminal to a base station, UECapabilityInformation, wherein the UECapabilityInformation includes first Quality Of Experience (QoE) capability information for Evolved UMTS Terrestrial Radio Access (E-UTRA), second QoE capability information for E-UTRA, first capability information for New Radio (NR), and second capability information for NR;
receiving, by the terminal from the base station, a first radio resource control (RRC) message, wherein the first RRC message includes first configuration information, wherein the first configuration information includes a first list and a rrc-SegAllowed, and wherein the first list includes at least one measConfigAppLayer;
configuring, by the terminal based on the at least one measConfigAppLayer, at least one application layer measurement;
receiving, by the terminal from the base station, a second RRC message, wherein the second RRC message includes a SuspendConfig;
storing, by the terminal in User Equipment (UE) Inactive Access Stratum Context, the at least one application layer measurement configuration;
receiving, by the terminal in RRC_INACTIVE, a third RRC message;
discarding, by the terminal and in response to the third RRC message, the stored at least one application layer measurement configuration; and
releasing, by the terminal, the at least one application layer measurement,
wherein the third RRC message is a paging message including a temporary terminal identifier allocated by a core network, and
wherein the rrc-SegAllowed controls segmentation of one or more RRC messages relating to the at least one measConfigAppLayer.

### Claim 2 (depends on 1)

The method of claim 1,
wherein the first QoE capability information indicates support of QoE measurement collection for streaming service and the second QoE capability information indicates support of QoE measurement collection for Multimedia Telephony Service for IMS (MTSI) service.

### Claim 3

A terminal in a wireless communication system, the terminal comprising:
a transceiver configured to transmit and receive a signal; and
a controller configured to control the transceiver to:
transmit, to a base station, UECapabilityInformation, wherein the UECapabilityInformation includes first Quality Of Experience (QoE) capability information for Evolved UMTS Terrestrial Radio Access (E-UTRA), second QoE capability information for E-UTRA, first capability information for New Radio (NR), and second capability information for NR;
receive, from the base station, a first radio resource control (RRC) message, wherein the first RRC message includes first configuration information, wherein the first configuration information includes a first list and a rrc-SegAllowed, and wherein the first list includes at least one measConfigAppLayer;
configure, based on the at least one measConfigAppLayer, at least one application layer measurement;
receive, from the base station, a second RRC message, wherein the second RRC message includes a SuspendConfig;
store, in User Equipment (UE) Inactive Access Stratum Context, the at least one application layer measurement configuration;
receive, in RRC_INACTIVE, a third RRC message;
discard, in response to the third RRC message, the stored at least one application layer measurement configuration; and
release the at least one application layer measurement,
wherein the third RRC message is a paging message including a temporary terminal identifier allocated by a core network, and
wherein the rrc-SegAllowed controls segmentation of one or more RRC messages relating to the at least one measConfigAppLayer.
