Equipment and method for controllking repetitive structure of subsystem of transceiver in base station

Abstract

An apparatus and method for controlling a duplication structure of a Base station Transceiver Subsystem (BTS) is provided. The BTS has N number of sectors including a first sector to an Nth sector and M number of Frequency Assignments (FAs) including a first FA to an Nth FA. The apparatus and method includes N number of power dividers, each of which has M number of output ports and one redundancy output port, each of the power dividers dividing an input signal into equal-power signals each having 1 / (M+1) power and outputting the power-divided signals through the M number of output ports and one redundancy output port. The apparatus and method further includes (NxM) number of receivers for demodulating signals outputted from the output ports of the N number of power dividers, respectively; a redundancy receiver for demodulating a signal which has been processed by and is switched over from one of the (NxM) number of receivers according to a predetermined control; a switch connected to each of redundancy output ports of the N number of power dividers, the switch connecting a signal outputted from one of the redundancy output ports to the redundancy receiver according to a predetermined control; and a controller which monitors operation states of the (NxM) number of receivers and controls the switch to connect a redundancy signal to the redundancy receiver when the controller detects one abnormally-operating receiver from among the (NxM) number of receivers, the redundancy signal being outputted from a redundancy output port of a power divider connected to the abnormally-operating receiver.

Description

technical field [0001] The present invention relates to a device and a method for a mobile communication system, in particular to a device and a method for controlling a repeating structure of a base transceiver station subsystem (BTS) in a mobile communication system with a sector structure. Background technique [0002] figure 1 is a block diagram depicting the internal structure of a conventional base transceiver subsystem with three sectors and two frequency assignments. [0003] Generally, a base station transceiver subsystem in a mobile communication system employing a Code Division Multiple Access (CDMA) scheme has a fan-shaped cell structure. The sectorized cell structure refers to a structure in which a cell covered by a BTS is divided into and managed with a predetermined number of sectors. Here, the BTS has a cell including three sectors α, β and γ. The number of frequency allocations used by the BTS may vary depending on circumstances. Also, the BTS employs a...

AI Technical Summary

Problems solved by technology

The increased number of ports in a switch also increases the size of the switch, causing the switch to take up more space

Moreover, as the number of ports increases, the auxiliary equipment used to control the ports also increases accordingly, thereby increasing the manufacturing cost

Also, there is no way to know the status of the redundant receiver until it is used

Therefore, even after switching the connection from the faulty receiver to the abnormally functioning redundant receiver, the signal processed by the faulty receiver cannot be demodulated, which causes the BTS to not work properly, thereby deteriorating the quality of service provided by the BTS
