Method, system and terminal for system update between mobile communication terminals

The embodiments of the present invention provide a method, system and terminal for system update between mobile communication terminals. The method includes the following steps: a destination mobile terminal judges whether it is compatible with a source mobile terminal on hardware; if the two parties are compatible on hardware, the destination mobile terminal obtains system backup files transmitted by the source mobile terminal through a wireless network; and the destination mobile terminal performs system update on the basis of the system backup files. The advantage of the above technical solutions provided by the embodiments of the present invention lies in that the system update can be realized between mobile phones through the wireless network, no longer depends on an update server, and does not need to download update files from the update server, and thereby the burden of the update server can be reduced and meanwhile it is good for the mobile phone users to exchange their systems conveniently. The success rate of the update can be ensured by judging whether the hardware of the two parties is compatible before an update. With the embodiments of the present invention, users are provided with more convenient update means to choose, rather than totally rely on the operator servers or professionals.

Reverse call origination via a packet switched network

A telephone call is originated in a reverse direction, i.e., from a called party to a calling party, using a packet switched network. According to one embodiment of the invention, a calling party located in a first country may wish to place a call to a party in a second country having cheaper telephone rates. To benefit from the cheaper telephone rates of the second country, the calling party sends a data message—via a packet switched network—to a service provider in the second country requesting reverse call origination. The request message may be sent to an electronic mailbox maintained by the service provider and located on a global computer network, such as the Internet. The service provider of the second country, upon receiving the message, dials the destination number of the called party supplied in the request message. After reaching the called party, the service provider of the second country dials the calling party and bridges the call between the two parties. The calls thus originate from and are billed at the lower telephone rates of the second country. In another embodiment of the present invention, a telephone call may originate from a service provider of a country having lower telephone rates even though the called and calling parties are located at other respective countries.

Sheet paper storage and dispensing device

A sheet paper storage and dispensing device according to the present invention stores and dispenses sheet paper, and includes: a first reel drum onto which a tape is wound from one side of the tape; a second reel drum on which sheet paper is stored by winding the tape thereon from an opposite side of the tape in a state in which the tape and sheet paper supplied from an external sheet paper transporting section to an intake/discharge port are mutually superimposed; a motor which drives the first reel drum and the second reel drum via a drive system; an electromagnetic clutch which switches between transmitting and interrupting drive force from the drive system; an electromagnetic brake which applies a brake to the drive system; a trigger sensor which detects supplying of the sheet paper from the sheet paper transporting section to the intake/discharge port; a tape speed detection section which detects a transporting speed of the tape at the intake/discharge port; a motor speed variation control unit which controls changes in a rotation speed of the motor; and a winding control unit which causes a winding operation by controlling the electromagnetic clutch so as to transmit the driving force of the motor when supplying of the sheet paper to the intake/discharge port is detected by the trigger sensor, the winding operation being a operation in which the tape is dispensed from the first reel drum while the tape is wound onto the second reel drum, so that the sheet paper supplied to the intake/discharge port is wound onto the second reel drum, the winding control unit controlling the motor speed variation control unit such that, during the winding operation, the transporting speed of the tape detected by the tape speed detection unit is held at a fixed speed which is faster by a predetermined amount than a transporting speed of the sheet paper transporting section.

System and device for managing control data

In one embodiment, a content data management system that handles control information on management of content data decryption includes a first device (a recorder / player) for recording / reproducing the content data, a second device (a magnetic disk drive) for storing the content data, and a host processor for controlling data transfer between the first and second devices. The host processor exercises control for the system to inquire of both devices as to a transfer function for internal data of the devices, then depending on particular inquiry results, set up, prior to the data transfer between the two devices, either a first transfer mode for transferring the control information unidirectionally from the first device to the second device, or a second transfer mode for transferring the control information bidirectionally between both devices, authenticate mutual validity between the first and second devices, share key data (symmetric key data) between the first and second devices if authentication results indicate validity, encrypt the control information with the first or second device by using the key data, and transfer the control information that has been encrypted with either device to the other device in the first or second transfer mode that has been set up.
