Title: Innovations of David Zhang in 5G Technology

Introduction

David Zhang, a prolific inventor based in San Jose, CA, has made significant contributions to the field of telecommunications, particularly in the development of 5G technologies. With a remarkable 24 patents to his name, Zhang is at the forefront of innovations that are shaping the future of mobile data communications.

Latest Patents

One of David Zhang's latest inventions is titled "Methods and systems for routing mobile data traffic in 5G networks." This routing platform is designed to manage both 4G and 5G mobile data traffic within mobile core networks, specifically implementing Option-3 of 5G Non-Standalone deployment. The platform operates by capturing S6a Diameter messages between a Mobility Management Entity (MME) and a Home Subscriber Server (HSS). It analyzes these messages to ascertain whether a user equipment (UE) is configured for a 5G data connection. If a GTP Create-Session-Request message from a Serving Gateway (SGW) is linked to a UE that has been determined to support a 5G connection, Zhang’s solution either forwards the message to a dedicated 5G Packet Network Data Gateway (PGW) or modifies the GTP message, enabling a single PGW to manage both 4G and 5G traffic effectively.

Another notable invention is the "System and method of selective packet data network gateway discovery." In this innovation, a Slicing Agent node is strategically deployed within the core network to select the appropriate Packet Data Gateway (PGW) based on the subscriber's profile and requirements. This Slicing Agent can be positioned in various core network setups globally, catering to both roaming and non-roaming subscribers without necessitating updates to legacy network nodes.
