A mobile communication method comprising: step A of notifying, by a radio base station (NodeB 01, Node B02), a radio network controller (RNC 01) of location information of the radio base station (NodeB 01, Node B02); step B of notifying, by the radio network controller (RNC 01), an exchange station (MSC/SGSN) of the location information of the radio base station (NodeB 01, Node B02)when a mobile station starts communication via the radio base station (NodeB 01, Node B02) and the radio network controller (RNC 01); and step C of controlling each session of the communication by the exchange station (MSC/SGSN) based on the location information of the radio base station (NodeB 01, Node B02), wherein the location information is information independent from a configuration of a mobile communication system including a location registration area configuration, a radio network controller connection configuration, a radio base station connection configuration, and a sector configuration, the radio base station (NodeB 01, Node B02) is configured to store the location information of the radio base station (NodeB 01, Node B02) and a r Geographical Area Identifier, GAI, associated with each other, the GAI being absolute geographic information independent from the configuration of the mobile communication system containing latitude and longitude information, the radio network controller (RNC 01) is configured to store the location information and the GAI associated with each other for each communication of the mobile station which is performed through the radio base station (NodeB 01, Node B02) and the radio network controller (RNC 01), the exchange station (MSC/SGSN) is configured to store the location information and a communication destination associated with each other, and to store the location information associated with each communication of the mobile station which is performed through the radio base station (NodeB 01, Node B02), the radio network controller (RNC 01), and the exchange station (MSC/SGSN), and in the step C, the exchange station (MSC/SGSN) connects the mobile station with the communication destination associated with the location information of the radio base station (NodeB 01, Node B02) in said communication. step A of notifying, by a radio base station (NodeB 01, Node B02), a radio network controller (RNC 01) of location information of the radio base station (NodeB 01, Node B02); step B of notifying, by the radio network controller (RNC 01), an exchange station (MSC/SGSN) of the location information of the radio base station (NodeB 01, Node B02)when a mobile station starts communication via the radio base station (NodeB 01, Node B02) and the radio network controller (RNC 01); and step C of controlling each session of the communication by the exchange station (MSC/SGSN) based on the location information of the radio base station (NodeB 01, Node B02), wherein the location information is information independent from a configuration of a mobile communication system including a location registration area configuration, a radio network controller connection configuration, a radio base station connection configuration, and a sector configuration, the radio base station (NodeB 01, Node B02) is configured to store the location information of the radio base station (NodeB 01, Node B02) and a r Geographical Area Identifier, GAI, associated with each other, the GAI being absolute geographic information independent from the configuration of the mobile communication system containing latitude and longitude information, the radio network controller (RNC 01) is configured to store the location information and the GAI associated with each other for each communication of the mobile station which is performed through the radio base station (NodeB 01, Node B02) and the radio network controller (RNC 01), the exchange station (MSC/SGSN) is configured to store the location information and a communication destination associated with each other, and to store the location information associated with each communication of the mobile station which is performed through the radio base station (NodeB 01, Node B02), the radio network controller (RNC 01), and the exchange station (MSC/SGSN), and in the step C, the exchange station (MSC/SGSN) connects the mobile station with the communication destination associated with the location information of the radio base station (NodeB 01, Node B02) in said communication.
