Abstract
A base station system supporting multi-sector/multi-FA in which, when a board goes out of order, a redundant board is automatically switched on, so as to prevent the call from being cut off and the entire capacity of the system from being influenced, thereby enabling the system to maintain normal operation and to be perfectly managed. In the base station system, signal transmitting and receiving paths of up- and down-converters are separated from each other, each board contains all FAs, and redundant boards are utilized, so that the system can normally operate in soft/hard-redundancy modes without cut-off of the call, even when a problem occurs in the paths.

A signal-receiving system of a base station system of a mobile communication system, the signal-receiving system comprising:
- at least one signal-receiving section;
- a down-converter including at least one down-converter board and at least one redundant down-converter board, wherein one board is selected from among the at least one down-converter board and the at least one redundant down-converter board for downwardly converting a frequency of a signal inputted through the signal-receiving section, the at least one down-converter board corresponding to the signal-receiving section;
- and
- a switching section connected between the signal-receiving section and the down-converter, the switching section being switched to connect the at least one down-converter board with the signal-receiving section when the at least one down-converter board is normal, and as to connect the at least one redundant down-converter board with the signal-receiving section when the at least one down-converter board is abnormal,
- wherein the at least one down-converter board and the at least one redundant down-converter board each comprise:
- a divider dividing the signal inputted through the signal-receiving section into a plurality of signals, a number of which corresponds to that of predetermined multi-frequency assignments (FAs);
- and
- a plurality of converters corresponding to the predetermined FAs for downwardly converting outputs of the divider for the corresponding FAs.
