In a communication system, even when a mobile terminal device belonging to some mobile carrier does not have a right or a qualification for accessing the fixed communication network via the local network/gateway that is given in advance, this mobile terminal device is enabled to access the fixed communication network via the local network/gateway, by carrying out a procedure for paying the fee from the user of the mobile terminal device to the fixed communication network provider or a procedure for monitoring the mobile terminal device. Also, a device other than the mobile terminal device is enabled to access the resource in the mobile carrier network to which the mobile terminal device belongs, from the local network through the mobile terminal device.

When a first mobile node is moved, it reports binding information including a compatible node identifier (virtual mobile guaranteed general network identifier and a node identifier) and a compatible position identifier to a first server which is assigned to the first mobile node. A second mobile node reports the binding information to a second server. For communicating with the second mobile node to which a second server is assigned, if the destination address of a packet addressed to the second mobile node is designated with a compatible node identifier, the first mobile node acquires the binding information of the second mobile node from the second server. Then, the first mobile node converts the destination address of the packet into the acquired compatible position identifier and sets the compatible position identifier of the first mobile node as the source address of the packet. The first mobile node then transmits the packet.

In the disclosed information delivery scheme for delivering WWW information provided by information servers on the Internet to mobile computers connected to the Internet through a wireless network, a plurality of cache servers capable of caching WWW information provided by the information servers are provided in association with the wireless network. The cache servers can be managed by receiving a message indicating at least a connected location of a mobile computer in the wireless network from the mobile computer, selecting one or more cache servers located nearby the mobile computer according to the message, and controlling these one or more cache servers to cache selected WWW information selected for the mobile computer, so as to enable faster accesses to the selected WWW information by the mobile computer. Also, the cache servers can be managed by selecting one or more cache servers located within a geographic range defined for an information provider who provides WWW information from an information server, and controlling these one or more cache servers to cache selected WWW information selected for the information provider, so as to enable faster accesses to the selected WWW information by the mobile computer.

摘要:
A disc cartridge for receiving a disc-like recording medium therewithin which recording medium is capable of being inserted and removed from the disc cartridge. The disc cartridge includes an insertion and removal port opening and closing member, and the disc insertion and removal port opening and closing member is moved from the disc cartridge when taking out the recording medium. The disc cartridge has a locking member for locking the insertion and removal port opening and closing member. At least a part of a locking cancellation preventing member which prevents the locking member from moving for canceling the locking is arranged on a moving path of the locking member so as to cancel the locking. Further, the locking cancellation preventing member is a portion for recognizing a history of insertion and removal of the recording medium.
