Abstract
A base station system and method for call setting up, handing over and releasing in hybrid network are disclosed. The base station system consists of BSC, TC, several BTSs and a band-width guaranteed IP (Internet Protocol) network among them, IP mode transport and traditional TDM mode transport between BSC and TC are simultaneity supported in the system, and BTS supports TDM mode or IP mode. The invention is provided with such advantages: compatibility with TDM, which maximally protects the providers' investment; smooth transition from TDM to IP, which decreases investing risk; flexible choice for different physical layer or data link layer transmission apparatuses to bear IP message, which facilitates the providers to constitute their networks. In IP mode, data service can share bandwidth with the mute frames of voice service, the system can coexist with different IP networks such as 3G or WiMax, and the control plane and the user plane is independent each other so as to simplify the developing procedure and reduce the maintaining cost.
