Title: Toshiya Ouchi: Innovator in Mobile Communication Technologies

Introduction

Toshiya Ouchi is an accomplished inventor based in Tokyo, Japan, known for his significant contributions to mobile communication technologies. With a number of two patents to his name, Ouchi has developed innovative systems that enhance the efficiency and effectiveness of data transmission in mobile networks.

Latest Patents

Ouchi's latest patents include a "Mobile communication system for providing IP packet communications and method for routing IP packets." This invention involves a complex framework where multiple packet gateways (PGWs) connect mobile communication systems to the internet, allowing the setup of corresponding IP subnetworks. The visitor location register (VLR) plays a critical role by notifying PGWs of the location information of mobile stations and the IP addresses of connected data terminals. If an IP address is linked to a different subnet, the PGW communicates with the corresponding PGW for routing purposes, thus managing the location data effectively.

Another notable patent is centered around a "Mobile communication network and control method thereof." This innovation features a network consisting of multiple base stations that engage with various mobile stations. The interconnected base station controllers (BSC) work cohesively to maintain decentralized storage of terminal information in local service points. In cases where essential data is not available locally, the BSC can request information from other BSCs, streamlining the authentication and location data retrieval process for mobile stations.
