Latest Patents
Ehara's latest patents include a "Communication method and radio network control device in a mobile communication system." This invention describes a mobile communication system where a mobile station copies data and transmits it to multiple base stations. Each base station sends the copied data to a serving radio network control device (S-RNC), which selectively combines and outputs the received data. A congestion monitoring unit is integrated to monitor the line's congestion state between the drift radio network control device (D-RNC) and S-RNC, optimizing data transmission based on the line's status.
Another notable patent is the "Communication method and intermediate network device with branch selection functions." This method is designed for a radio communications system where a mobile station sends identical data to several radio base stations simultaneously. The intermediate network device monitors the continuity of sequence numbers to detect any missing data. Based on this analysis, the device determines which base stations should continue forwarding data, enhancing the overall efficiency of the communication system.
