Abstract
Abstract A mobile communication system includes first and second switching apparatuses, an information channel provided between the first and second switching apparatuses, a plurality of base stations managed by each of the first and second switching apparatuses, and a mobile station. The mobile station can communicate with the first switching apparatus through one of the plurality of base stations managed by the first switching apparatus and with the second switching apparatus through one of the plurality of base stations managed by the second switching apparatus. The first and second switching apparatuses detect traffics therethrough as first and second traffics, respectively, and the second switching apparatus notifies the second traffic to the first switching apparatus via the information channel. The first switching apparatus controls the mobile station and the second switching apparatus based on the first and second traffics such that the mobile station which is currently communicating with the first switching apparatus communicates with the second switching apparatus.
