Document Type and Number:
Japanese Patent JP2656977
Kind Code:
B2
Abstract:
PURPOSE:To increase a connection switching processing speed at the time when an application program of the transfer request destination is managed by the same host system as the transfer request source by providing a transfer request destination judging part and a coupling relation switching part. CONSTITUTION:When a data processing part 10 informs a communication control part 12 to transfer the use right of a terminal 3, which the data processing part 10 uses at present, to a data processing part 11, a transfer request destination judging part 13 judges whether the data processing part 11 of the transfer request destination is under management of a first host system 1 or not. When it is under management of the first host system 1, a coupling relation switching part 14 settles internal coupling relations between the data processing part 11 and the terminal 3 and reports the request for switching to the data processing part 11 to a communication control part 20 of a second host system 2 through a communication line 4, and a communication disconnecting part 21 disconnects communication between the terminal 3 and the data processing part 10. Thus, one set of control data is only transmitted and received to realize the switching processing of connection to the terminal 3.
