1. A mobile communication method, comprising:
- a step A of transmitting first instruction information to a radio base station configured to manage a cell of a first frequency when a mobile station communicating in a cell of the first frequency detects an entry into a predetermined area corresponding to a particular cell using a second frequency; and
a step B of transmitting second instruction information to the radio base station when the mobile station detects an exit from the predetermined area;
a step of the radio base station transmitting, when receiving the first instruction information, a measurement configuration instructing the measurement of a radio quality in a cell of the second frequency to the mobile station; and
a step of the radio base station transmitting, when receiving the second instruction information, a measurement configuration instructing an interruption of measurement of the radio quality in the cell of the second frequency to the mobile station, whereinin the step A, when a predetermined period has not elapsed since the time of transmission of the first instruction information or the second instruction information, the mobile station does not transmit the first instruction information even when the entry into the predetermined area is detected, andin the step B, when a predetermined period has not elapsed since the time of transmission of the first instruction information or the second instruction information, the mobile station does not transmit the second instruction information even when the exit from the predetermined area is detected.

Abstract
To appropriately transmit “entering/leaving proximity indication” while preventing the wastage of radio resources. A mobile station UE according to the present invention is configured not to transmit “entering proximity indication” even when an entry into a predetermined area #1 is detected, and not to transmit “leaving proximity indication” even when an exit from the predetermined area #1 is detected, when a predetermined period has not elapsed since the time of transmission of “entering proximity indication” or “leaving proximity indication”.

9. A mobile station, comprising:
-
a transmission unit configured to transmit first instruction information to a radio base station configured to manage a cell of a first frequency when an entry into a predetermined area corresponding to a particular cell using a second frequency is detected during communication in the cell of the first frequency, and to transmit second instruction information to the radio base station when an exit from the predetermined area is detected; a step of the radio base station transmitting, when receiving the first instruction information, a measurement configuration instructing the measurement of a radio quality in a cell of the second frequency to the mobile station; and a step of the radio base station transmitting, when receiving the second instruction information a measurement configuration instructing an interruption of measurement of the radio quality in the cell of the second frequency to the mobile station, wherein the transmission unit is configured not to transmit the first instruction information, even when the entry into the predetermined area is detected, when a predetermined period has not elapsed since the time of transmission of the first instruction information or the second instruction information, and the transmission unit is configured not to transmit the second instruction information, even when the exit from the predetermined area is detected, when a predetermined period has not elapsed since the time of transmission of the first instruction information or the second instruction information. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
