Title: Eri Kawai: Innovator in Communication Systems

Introduction

Eri Kawai is a prominent inventor based in Yokohama, Japan. She has made significant contributions to the field of communication systems, holding a total of 13 patents. Her innovative work focuses on enhancing communication technologies, making them more efficient and user-friendly.

Latest Patents

Among her latest patents is a communication system and server that features a SOAP-SIP adapter. This adapter establishes a session with terminals in accordance with a SIP protocol. During this process, the SOAP-SIP adapter sends an INVITE message that includes its own IP address and port number to the terminals. Each terminal responds with a 200 OK message, which also includes its own IP address and port number. The SOAP-SIP adapter then stores this information in memory, allowing it to transfer media streams received from each terminal to the corresponding destination. Additionally, a pseudo RBT is sent to terminal A while establishing the session with terminal B to prevent any silent state.

Another notable patent involves a communication system and server that includes multiple memory units. These units store terminal information, outgoing call history, and incoming call history for at least one of the terminals involved. A processing unit reads this information to control the connection between the terminals and the communication device, ensuring that both parties can effectively communicate.
