Abstract
A paging signal transmission method which transmits the paging signal to a position registration area of a mobile station in response to incoming to the mobile station. When a wireless base station managing a cell belonging to the position registration area of the mobile station does not permit access to the mobile station, the method does not transmits the paging signal to the cell.
Claims8
A paging signal transmission method comprising:
- receiving an incoming call addressed to a mobile station;
- and
- restricting transmission of an initial paging signal from a femto radio base station managing a cell belonging to a location registration area of the mobile station based on the incoming call addressed to the mobile station, when the femto base station has a same location registration area identification that is assigned to a macro-cell radio base station and the femto radio base station is not accepting access from the mobile station.
A femto radio base station used in a mobile communication system and that manages a cell belonging to a location registration area of a mobile station, the femto radio base station comprising:
- an interface that receives a paging signal in response to an incoming call addressed to the mobile station;
- and
- a processor that restricts the femto radio base station from transmitting an initial paging signal based on the received paging signal to the cell when the femto base station has a same location registration area identification that is assigned to a macro-cell radio base station and the femto radio base station is not accepting access from the mobile station.
A network device used in a mobile communication system in which a paging signal is transmitted to a location registration area of a mobile station in response to an incoming call addressed to the mobile station, the network device comprising:
- an interface that receives the incoming call addressed to the mobile station;
- and
- a processor that restricts a femto radio base station managing a cell belonging to the location registration area of the mobile station from transmitting an initial paging signal based on the incoming call addressed to the mobile station when the femto base station has a same location registration area identification that is assigned to a macro-cell radio base station and the femto radio base station is not accepting access from the mobile station.
