COMBINER FOR USE IN MULTI-BAND BASE STATION AND METHOD FOR CONTROLLING COMBINER
First Claim
1. A combiner utilized in a multi-band base station system and including a plurality of first ports assigned different frequency bands and a second port in connection with a common feeder cable, the combiner comprising:
- DC signal lines branching from each of the plurality of first ports and the second port, the DC signal lines branching from the first ports being connected to the DC signal line branching from the second port;
control signal lines branching from each of the plurality of first ports and the second port;
switching modules provided on each of the DC signal lines branching from the first ports and the second port;
modems provided on each of the control signal lines to modulate or demodulate an input control signal; and
a control unit configured to control switching of each of the switching modules according to an operation type of the combiner,wherein the operation type comprises a first type being responsive to signal inputs through at least some of the plurality of first ports and a second type being responsive to a signal input through the second port.

Abstract
The present disclosure relates to a combiner utilized in a multi-band base station system and including a plurality of first ports assigned different frequency bands and a second port in connection with a common feeder cable, including DC signal lines each branching from each first port and the second port, control signal lines each branching from each first port and the second port, switching modules on each of the DC signal lines, modems provided on each control signal line to modulate or demodulate an input control signal, and a control unit configured to control switching of each switching module according to an operation type of the combiner. The operation type includes a first type being responsive to signal inputs through at least some of the plurality of first ports and a second type being responsive to a signal input through the second port.

19. A method of controlling a signal input/output at a combiner including a plurality of first ports respectively assigned different frequency bands and a second port connected with a common feeder cable, the method comprising:
-
identifying whether an operation type of the combiner is a first type or a second type, the first type being responsive to signals input through at least some of the plurality of first ports and the second type being responsive to a signal input through the second port; when an identified type is the first type, transferring a DC signal of a first port through which a signal is input among the first ports to the second port, and processing a control signal of the first port through which the signal is input for transferring to the second port; and when the identified type is the second type, transferring a DC signal of the second port to a first port determined based on a preset information among the first ports, and processing a control signal from the second port for transferring to the first port determined determined based on a preset information.
