Latest Patents

Among his latest inventions, Yanagisako has developed a **Communication System and Control Method** that dramatically improves the success rate of handovers in mobile networks. This system features a base station and a mobile management device. The mobile management device includes first reception means for receiving speed information on a mobile terminal based on measurement information by Minimization of Driving Test (MDT), and first transmission means for relaying messages that include this speed information to the base station. In turn, the base station is equipped with second reception means for receiving this speed information and control means for managing handover processes effectively based on the data received.

Another notable patent is the **Heterogeneous-Network-Use Base Station, Mobile Communication Device, and Communication Method**. In this invention, Yanagisako addresses the low reliability of measurement data obtained by mobile devices in a standby state within heterogeneous networks. The base station broadcasts information that includes Almost Blank Subframe (ABS) data which sets the subframe pattern used for MDT measurements, ensuring a more reliable process. The mobile communication device is designed to receive this broadcast information, detect the appropriate subframe pattern, perform necessary measurements, and transmit the result as measurement data.
