Title: Siu Bun Chan: Innovator in Mobile Network Technology
Introduction
Siu Bun Chan is a prominent inventor based in Kowloontong, China, known for his significant contributions to mobile network technology. With a total of seven patents to his name, Chan has made remarkable advancements in optimizing mobile network bandwidth and enhancing wireless communication systems.
Latest Patents
One of Chan's latest patents focuses on optimizing mobile network bandwidth. This innovation involves a gateway that transforms encrypted PS data traffic on the Iub interface into clear IP packets. This process allows for WAN stream de-duplication and other optimizations, effectively eliminating the transfer of repetitive data across the Iub interface. As a result, the throughput between the NodeB and the RNC of the WCDMA network is significantly increased. The gateway efficiently extracts PS data traffic from Iub without interfering with signaling and CS traffic. The bifurcated PS data traffic is then redirected to the GTP I/O port of the gateway, where stream de-duplication is applied. Notably, the deployment of this gateway is transparent to the WCDMA network, requiring no network reconfiguration.
Another significant patent by Chan is the base station subsystem multiplexer with support for local switching. In this embodiment, a wireless system comprises a host MSC/VLR of a public land mobile network (PLMN) and multiple base station subsystems (BBSs). Each BSS includes a respective base station controller (BSC) and one or more base transceiver stations (BTSs). The system also features a virtual base station controller (VBSC) that is communicatively linked to the BSSs and the host MSC/VLR. From the perspective of the host MSC/VLR, the VBSC functions as a base station controller for the BTSs in the BSSs. This innovation allows for local call switching within the BSSs, enhancing the efficiency of wireless communication.
