Title: Ken Takashima: Innovator in Mobile Communication Systems

Introduction

Ken Takashima is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of mobile communication systems. With a total of 2 patents, his work focuses on enhancing communication methods and network control devices.

Latest Patents

Takashima'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 also included to manage line congestion between the drift radio network control device (D-RNC) and S-RNC. When congestion occurs, the D-RNC selectively combines the copied data from the base stations and sends it to the line. Conversely, when the line is not congested, the D-RNC transmits the copied data without selective combination.

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 multiple radio base stations simultaneously. The intermediate network device monitors the continuity of sequence numbers attached to the data received from each base station. It detects missing sequence numbers and, based on this information, selects which base station should continue forwarding data while requesting others to stop.
