Radio measurement collection method and radio terminal
First Claim
1. A radio base station for a radio measurement collection method using a radio terminal configured to perform a logging process of storing a measurement log including a measurement result of a radio environment according to a measurement configuration set by a measurement configuration message received from a network, the radio base station comprising:
- a transmitter that transmits, to the radio terminal, a log transmission request to request a transmission of the measurement log; and
a receiver that receives, from the radio terminal, a log transmission response to transmit the measurement log, whereinthe measurement configuration includes a timer that defines duration of the logging process, andthe receiver receives, from the radio terminal, the log transmission response even when the measurement log is not stored in the radio terminal due to lapse of 48 hours after an expiry of the timer.

Abstract
A radio measurement collection method using UE configured to perform a process of retaining a measurement log including a measurement result of a radio environment according to a measurement configuration set by a measurement configuration message received from a network includes a step S109 in which the network transmits a UEInformationRequest message to request a transmission of the measurement log to the UE, and a step S110 in which the UE transmits a UEInformationResponse message to transmit the measurement log to the network. In step S110, the UE transmits the UEInformationResponse message to the network even when the measurement log is not retained.

2. A radio base station for a radio measurement collection method using a radio terminal configured to perform a logging process of storing a measurement log including a measurement result of a radio environment according to a measurement configuration set by a measurement configuration message received from a network, the radio base station comprising:
-
a receiver that receives, from the radio terminal, log storing information indicating that the measurement log is stored in the radio terminal, at a time of transition to a connected state from an idle state of the radio terminal; and a transmitter that transmits, to the radio terminal, a log transmission request to request a transmission of the measurement log on the basis of the log storing information, wherein the receiver further receives, from the radio terminal, a log transmission response to transmit the measurement log, the measurement configuration includes a timer that defines duration of the logging process, and the receiver receives, from the radio terminal, the log transmission response even when the measurement log is not stored in the radio terminal due to lapse of 48 hours after an expiry of the timer.

3. A radio measurement collection method using a radio terminal configured to perform a logging process of storing a measurement log including a measurement result of a radio environment according to a measurement configuration set by a measurement configuration message received from a network, the radio measurement collection method performed at a radio base station and comprising:
-
transmitting, to the radio terminal, a log transmission request to request a transmission of the measurement log; and receiving, from the radio terminal, a log transmission response to transmit the measurement log, wherein the measurement configuration includes a timer that defines duration of the logging process, and the radio base station receives, from the radio terminal, the log transmission response even when the measurement log is not stored in the radio terminal due to lapse of 48 hours after an expiry of the timer.
