发明名称 ECONOMICAL SYNCHRONIZATION SYSTEM FOR ASYNCHRONOUS TRANSFER MODE MOBILE COMMUNICATION NETWORK WITHOUT DEPENDENCE ON EXTERNAL SYSTEM
摘要 An asynchronous transfer mode network includes a high-level station and a mobile station in a boundary zone between service cells of wireless base stations connected to the high-level station through asynchronous transfer mode channels, wherein the high level station transmits a control message through the asynchronous transfer mode channels and the wireless base stations to the mobile station and receives response messages from the mobile station through the wireless base stations and the asynchronous transfer mode channels, and determines a difference between transmission time lags along the asynchronous transfer mode channels so as to make built-in clocks provided for the wireless base stations synchronous with one another.
