RADIO COMMUNICATION METHOD

摘要

PROBLEM TO BE SOLVED: To improve the success probability of calling and call reception by using a radio communication system of a large cell when a mobile station is resident at the outside of a small cell but in the coverage of the large cell. SOLUTION: Control information of a different radio communication system is used in common, disable acquisition of a signal by the communication system of a small cell 102 is informed to a base station 100 in an adjacent small cell by using the communication system of a large cell 112 able to acquire the signal. That is, when the base station 100 of the small cell 102 and the terminal equipment 101 cannot acquire the control signal of the outgoing or incoming call from the communication system of the large cell 112 to the communication system of the small cell 102, the communication system of the large cell 112 is used to control the method such that a control signal is being sent within a predetermined time from the base station 100 of the communication system of the small cell 102 to the terminal equipment 101.
