To reduce a load on a vehicle when determining a base station of a switching destination, and to stably perform communication between the base station and the vehicle.SOLUTION: A server system 2 includes at least a storage unit (22) having a database accumulating a plurality of time portions of sets of the location of a vehicle at a particular point in time, information on the base station that has emitted the radio waves received by the vehicle at the location, and information including the strength of radio waves received by the vehicle at the location, a receiving unit (23) that receives various information including the location of a target vehicle (3), an identification unit (214) that identifies the most suitable base station for the target vehicle (3) when the receiving unit (23) receives the various information on the basis of the various pieces of information received by the receiving unit (23) and the database, and a transmission unit (24) that transmits a connection instruction to the base station identified by the identification unit (214) to the target vehicle (3).SELECTED DRAWING: Figure 4

    【課題】切替先の基地局を決定する際の車両の負荷を低減するとともに、基地局-車両間の通信を安定的に行えるようにする。【解決手段】サーバシステム2は、少なくとも、一の時点における車両の位置、当該位置にあるときの車両が受信した電波を発した基地局に関する情報、および当該位置にあるときの車両が受信した電波の強度を含む情報の組が複数時点分蓄積されたデータベースを有する格納部(22)と、対象車両(3)の位置を含む各種情報を受信する受信部(23)と、受信部(23)が受信した各種情報、およびデータベースに基づいて、受信部(23)が各種情報を受信したときの対象車両(3)にとって最適な基地局を特定する特定部(214)と、特定部(214)が特定した基地局への接続指示を対象車両(3)へ送信する送信部(24)と、を備える。【選択図】図4
