Abstract: A base station (1) is connectable to a mobile station (4) by a plurality of Radio Access Technologies (RATs) including first and second RATs. The base station (1) is configured to be able to use a communication path (400) that passes through a first upstream network (140) corresponding to the first RAT, when the mobile station (4) performs communication via the second RAT. This enables, for example, efficient use of the upstream networks when the Multi-RAT base station (1) supports a plurality of upstream networks.
