Mobile communication method, femtocell radio base station, and network apparatus

摘要

The disclosed mobile communication method is a mobile communication method in a mobile communication system, wherein at least a part of a macro-cell (#A), with which first broadcast information is transmitted at a first frequency, and a femto cell (#a), in which second broadcast information is transmitted at a second frequency, overlap geographically. The method has step in which a wireless base station (#a) for a femto cell that manages the femto cell (#a) detects the first broadcast information, step in which the wireless base station (#a) for a femto cell transmits guiding broadcast information at a first frequency in response to detection of the first broadcast information, and step (C) in which a mobile station (UE #1) that is communicating in the macro-cell (#A) performs handover to the femto cell (#a) when the guiding broadcast information is detected.

1. A mobile communication method in a mobile communication system in which a macro cell where first broadcast information is transmitted using a first frequency geographically overlaps at least partially with a femtocell where second broadcast information is transmitted using a second frequency, the method comprising:
step A of, based on a setting according to the first broadcast information, transmitting guiding broadcast information guiding the mobile station to the femtocell by the femtocell radio base station using the first frequency in a pilot cell that geographically overlaps with the femtocell; step B of performing a handover or cell reselection to the femtocell by a mobile station communicating in the macro cell, when the mobile station detects the guiding broadcast information; and step C of determining, by the femtocell radio base station, to transmit the second broadcast information in the femtocell by using the second frequency on the basis of broadcast information transmitted in a neighboring cell.
