A mobile communication method according to the present invention includes a step A of generating and storing, by a mobile station UE in a standby state, a MDT log including predetermined information in a period defined by a “Logged MDT measurement period”, a step B of generating and storing, by the mobile station UE, the MDT log when a standby cell is changed, and a step C of transmitting, by the mobile station UE, the stored MDT log to a radio base station eNB after the mobile station UE is changed to an active state.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A mobile communication method comprising: a step A of generating and storing, by a mobile station in a standby state, log information including predetermined information in a predetermined period; a step B of generating and storing, by the mobile station, the log information when a standby cell is changed; and a step C of transmitting, by the mobile station, the stored log information to a radio base station after the mobile station is changed to an active state.
2. The mobile communication method according to claim 1 , wherein, in the step B, the mobile station generates and stores, as the predetermined information, the log information including at least one of identification information of a changed standby cell, radio quality in the changed standby cell, time information, and location information.
3. The mobile communication method according to claim 1 , wherein, after a time point at which a changed standby cell is initially selected, the mobile station generates and stores the log information in the predetermined period.
4. A mobile station comprising: a management unit that generates and stores log information including predetermined information in a predetermined period when the mobile station is in a standby state; and a transmission unit that transmits the stored log information to a radio base station after the mobile station is changed to an active state, wherein when the mobile station changes a standby cell, the management unit is configured to generate and store the log information.
5. The mobile station according to claim 4 , wherein the management unit is configured to generate and store, as the predetermined information, the log information including at least one of identification information of a changed standby cell, radio quality in the changed standby cell, time information, and location information.
6. The mobile station according to claim 4 , wherein, after a time point at which a changed standby cell is initially selected, the management unit is configured to generate and store the log information, in the predetermined period.
