Abstract
A radio base station in a first mobile communication system is disclosed. The radio base station includes a radio communication unit; a network communication unit; and a determining unit. If a massage received by the network communication unit from a switching station indicates that a mobile station is requesting a service which is not provided in the first mobile communication system but which is provided in, a second mobile communication system and it is determined by the determining unit that a handover to the second mobile communication system cannot be conducted, the network communication unit requests the switching station to release a connection with the mobile station. Then the radio communication unit reports to the mobile station that the connection should be released in accordance with an instruction from the switching station.
