An ASN-GW (4) that controls communication of a plurality of BSs (3) of which each wirelessly accommodates MS (2) includes a PGID management table (23A) that manages PG #1 to be set for macro BSs (3A) and PG #2 to be set for a femto BS (3B), a location registration database (23B) that manages PGID of identifying PG in which the MS (2) is currently located and last BSID of identifying BS (3) that performs final location registration of the MS (2), and a GW-side control unit (24) that transmits, upon receiving data for the MS (2), paging information through all the macro BSs (3A) under the PG #1 when the present position of the MS is the PG #1, and that transmits, upon receiving data for the MS (2), the paging information through the femto BS (3B) under the PG #2 based on the last BSID when the present position of the MS (2) is the PG #2. Therefore, the transmission of useless paging information is avoided and thus stable paging control can be realized. |
