1. A centralized base station system based on advanced telecommunication computer architecture ATCA including a main base station subsystem and one or more remote radio frequency subsystems, said remote radio frequency subsystem being in charge of signal reception and transmission of respective cells, said main base station subsystem comprising:

  • one or more shelves based on ATCA platform, each shelf comprising at least one control switch module of ATCA board form;

    one or more base station controller interface modules in form of ATCA boards inserted into the shelves, for providing transmission interfaces with the base station controller for the base station system;

    a signaling module in form of a ATCA board inserted into the shelf, for performing protocol processing required by the signaling transmission between the base station system and the base station controller, so as to provide processing support for said base station controller interface unit;

    one or more baseband processing modules in form of ATCA boards inserted into the shelves, for performing baseband processing of wireless protocol physical layer procedure to uplink wireless signals from the cells and a downlink user data flow from the base station controller;

    one or more remote radio frequency interface modules in form of ATCA boards inserted into the shelves, for providing interfaces with the remote radio frequency subsystems for the main base station subsystem;

    a first switch network comprising shelf back board BASE interface links, said control switch modules and a first network switch unit, wherein the modules of said base station controller interface module, signaling module, baseband processing module and remote radio frequency interface module in the same shelf are connected to the control switch module through the shelf back board BASE interface links, the control switch module provides data exchange within the shelf, the control switch modules within the respective shelves are connected to the first network switch unit, and the first network switch unit provides data exchange between the shelves;

    a second switch network comprising shelf back board FABRIC interface links, said control switch modules and a second network switch unit, wherein the modules of said baseband processing module and remote radio frequency interface module in the same shelf are connected to the control switch module through the shelf back board FABRIC interface links, the control switch module provides baseband signal flow exchange within the shelf, the control switch modules within the respective shelves are connected to the second network switch unit, and the second network switch unit provides baseband signal flow exchange between the shelves;

    a clock synchronization network comprising a shelf back board clock synchronization bus, said control switch module and a clock unit, wherein the clock unit is used for obtaining a reference clock and providing a clock synchronization signal to the control switch modules of the respective shelves, the control switch module provides the clock synchronization signal to the respective modules in the same shelf through the shelf back board clock synchronization bus; and

    a signal transmission network for transmitting baseband signal flows between the remote radio frequency interface modules and the remote radio frequency subsystems,wherein said second network switch unit and clock unit are further connected to the first network switch unit so as to be connected to the first switch network, and said control switch module is in charge of controlling respective portions in the same shelf, and wherein one of the control switch modules of all the shelves is a main control module in charge of controlling the control switch modules within other shelves and other components outside the shelves within the system through the first switch network.
