Latest Patents

Kazuhiro Sasame holds a patent for a "Terminal Usage Limiting Apparatus." This invention is designed to limit the use of portable telephones within a predetermined area. The apparatus functions by providing service to mobile terminals in a usage-limiting area. It outputs control signals as a base station and sends additional usage limit messages. The mobile terminal recognizes the apparatus as a base station, allowing it to switch from the base station to the apparatus. Consequently, the mobile terminal receives a usage limit message and enters a predetermined operation limit mode where call originations are restricted. In this mode, the mobile terminal also receives control messages that include a long code mask corresponding to the apparatus. This unique long code mask further limits the mobile terminal's ability to receive calls from base stations via the paging channel.
