TL;DR: In this paper, a roaming terminal enciphers a subscriber's number thereof using a public key of a home network and sends the enciphered subscriber number to the home network via a roamed network.
Abstract: A roaming terminal enciphers a subscriber's number thereof using a public key of a home network and sends the enciphered subscriber's number to the home network via a roamed network. The home network deciphers the enciphered subscriber's number using a secret key to derive the subscriber's number. The home network generates a temporary authentication key and enciphers it using a public key of the roaming terminal corresponding to the subscriber's number. Then, the home network notifies the temporary authentication key and the enciphered temporary authentication key to the roamed network which then notifies the roaming terminal of the enciphered temporary authentication key and a random number generated at the roamed network. Then, an authentication process for the roaming terminal is performed between the roaming terminal and the roamed network using the random number, the temporary authentication key and the enciphered temporary authentication key. After completion of the authentication, the roamed network acquires a roaming number of the roaming terminal and notifies it to the roaming terminal and the home network. The roaming terminal, the roamed network and the home network store the roaming number and the temporary authentication key, respectively.

TL;DR: The solid-state image sensor disclosed in this paper includes a package accommodating an image sensor element chip and a plurality of wiring patterns carried by a flexible printed wiring circuit board, each of the wiring patterns is a continuous seamless pattern and has electrode portions for connection with the element chip, and a wiring portion disposed between those electrode portions.
Abstract: The solid-state image sensor disclosed includes a package accommodating an image sensor element chip, and a plurality of wiring patterns carried by a flexible printed wiring circuit board. Each of the wiring patterns is a continuous seamless pattern and has electrode portions for connection with the element chip and for connection with circuit components, and a wiring portion disposed between those electrode portions. The flexible printed wiring circuit board is capable of being bent, extends through and out from the package, and is unitary with the package. The arrangement enables the compact accommodation of the element chip together with other components and the reduction in the number of steps for the fabrication.

TL;DR: In this paper, a passive optical network is coupled to the wireless base station at the central office to provide a link to extend an antenna for wireless operations of the wireless BS to a remote site such that a wireless signal from the BS is transmitted in parallel with a passive fiber network signal through the link.
Abstract: A network system and method include a wireless base station integrated at a central office of a service provider. The wireless base station is configured to provide portable and fixed services to customers. A passive optical network is coupled to the wireless base station at the central office to provide a link to extend an antenna for wireless operations of the wireless base station to a remote site such that a wireless signal from the wireless base station is transmitted in parallel with a passive fiber network signal through the link.

TL;DR: In this paper, a cellular type mobile communication system comprising a plurality of cells, the plurality of base stations disposed in the respective cells, and a mobile station located in the cells is considered, where each base station increases or decreases the transmission power in response to the control command.
Abstract: A cellular type mobile communication system comprising a plurality of cells, a plurality of base stations disposed in the respective cells, and a mobile station located in the cells. On reception of a control command for a transmission power from the mobile station, each base station increases or decreases the transmission power in response to the control command. In addition, each base station renews the transmission power so that the transmission power after increased or decreased approaches a predetermined reference power.
