Latest Patents

One of Qunfeng Shang's latest patents is titled "Base station system and method for call setting up, handing over and releasing in hybrid network." This invention discloses a base station system that consists of a Base Station Controller (BSC), a Traffic Controller (TC), several Base Transceiver Stations (BTSs), and a bandwidth guaranteed IP network. The system supports both IP mode transport and traditional Time Division Multiplexing (TDM) mode transport between the BSC and TC simultaneously. The BTS can operate in either TDM mode or IP mode. The advantages of this invention include compatibility with TDM, which protects providers' investments, and a smooth transition from TDM to IP, reducing investment risks. Additionally, it allows for flexible choices in physical layer or data link layer transmission apparatuses to carry IP messages, facilitating network construction for providers. In IP mode, data services can share bandwidth with voice service mute frames, and the system can coexist with various IP networks, such as 3G or WiMax. The control and user planes operate independently, simplifying development and reducing maintenance costs.
