Claims

1. A communication system, comprising:

a location management server for managing a location of a mobile station;

a base station for deciding an exchange which accommodates the mobile station via the base station in response to a location registration request from the mobile station and making the location registration request to the exchange decided; and

an exchange for making the location registration request to the location management server in response to the location registration request from the base station,

wherein the location management server designates an exchange for accommodating the mobile station in response to the location registration request, and

wherein, when the location management server decides that an exchange different from the exchange which has made the location registration request is to be the exchange for accommodating the mobile station, the location management server instructs the base station which has made the location registration request to make a location registration request again via the different exchange, thereby the mobile station can selectively be accommodated by an exchange different from the exchange normally associated with the base station as would normally be selected by the base station to make the location registration request from a mobile station contacting the base station.
