Method for handover between different radio access schemes and wireless communication system

A mobile station which is capable of communicating with a plurality of base stations, each of which supports at least one of two or more radio access schemes, comprising:

• a demultiplexer for demultiplexing transfer information from a control signal received via a first base station from a second base station before the mobile station moves from the first base station to the second base station, wherein the transfer information specifies a radio access scheme allowing the mobile station to make at least initial connection to the second base station;
• and
• a communication section for performing the initial connection to the second base station according to the radio access scheme of the second base station included in the transfer information,
• wherein the second base station notifies the mobile station, via the first base station, of the transfer information which specifies a selected one of the two or more radio access schemes, when the second base station supports the two or more radio access schemes, to make the at least initial connection during a handover from the first base station to the second base station.

A wireless communication system comprising a plurality of base stations and at least one mobile station, wherein each of the plurality of base stations supports at least one of two or more radio access schemes and the mobile station is operable in the two or more radio access schemes, wherein

• each of the plurality of base stations comprises:
• a base station communication section for communicating with a mobile station in at least one of two or more radio access schemes;
• and
• a notifying section for notifying the mobile station, via another base station currently communicating with the mobile station, of transfer information which specifies a radio access scheme allowing the mobile station to make at least initial connection to the base station before the mobile station moves from said other base station to the base station, and
• the mobile station comprises:
• a demultiplexer for demultiplexing transfer information from a control signal via a first base station from a second base station before the mobile station moves from the first base station to the second base station, wherein the transfer information specifies a radio access scheme allowing the mobile station to make at least initial connection to the second base station;
• and
• a mobile station communication section for performing the initial connection to the second base station according to the radio access scheme of the second base station included in the transfer information,
• wherein the second base station notifies the mobile station, via the first base station, of the transfer information which specifies a selected one of the two or more radio access schemes, when the second base station supports the two or more radio access schemes, to make the at least initial connection during a handover from the first base station to the second base station.

A computer program, embedded in a non-transitory computer readable medium, instructing a program-controlled processor of a mobile station which is capable of communicating with a plurality of base stations, each of which supports at least one of two or more radio access schemes, comprising:

• demultiplexing transfer information from a control signal received via a first base station from a second base station before the mobile station moves from the first base station to the second base station, wherein the transfer information specifies a radio access scheme allowing the mobile station to make at least initial connection to the second base station;
• and
• performing the initial connection to the second base station according to the radio access scheme of the second base station included in the transfer information,
• wherein the second base station notifies the mobile station, via the first base station, of the transfer information which specifies a selected one of the two or more radio access schemes, when the second base station supports the two or more radio access schemes, to make the at least initial connection during a handover from the first base station to the second base station.
