Radio measurement collection method, radio terminal, and radio base station

摘要

In one embodiment, a radio measurement collection method comprises: a step S11 of transmitting, by a E-UTRAN, a MDT Configuration message including a measurement trigger to the radio terminal UE; a step S14 of setting, by the radio terminal UE, the measurement trigger included in the MDT Configuration message received from the E-UTRAN in the radio terminal, and then performing radio environment measurement when an event corresponding to the measurement trigger occurs in an idle state and recording measurement data including a result of the measurement and location information; a step of S16 of transmitting, by the radio terminal UE, trigger type information indicating the measurement trigger to the E-UTRAN when the radio terminal UE is transitioned to a connected state from the idle state; and a step S17 of determining, by the E-UTRAN, whether to request the radio terminal UE to transmit the measurement data on the basis of the trigger type information from the radio terminal UE.

1. A radio measurement collection method comprising:
a step of transmitting, by a network including a radio base station, a setup message including a measurement trigger to a radio terminal; a step of setting, by the radio terminal, the measurement trigger included in the setup message received from the network in the radio terminal, and then performing radio environment measurement in response to the measurement trigger such that the measurement trigger of an event trigger type is prioritized over the measurement trigger of a periodical type and recording measurement data including a result of the measurement and location information in an idle state; and a step of transmitting, by the radio terminal, the measurement data and trigger type information indicating a type of the measurement trigger to the network, wherein the trigger type information indicates an event for initiating the radio environment measurement in the radio terminal.
