The present invention relates to a distributed communications system. The distributed communications system comprises: a plurality of digital units each of which receives a communications signal in a heterogeneous network, and generates CPRI data; a framer which converts the CPRI data outputted from the digital units into frames for optical transmission, and outputs the frames for optical transmission; a deframer which divides, into CPRI data, the frames for optical transmission outputted from the framer through an optical line, separately; and a plurality of remote units each of which receives each CPRI data outputted from the deframer. According to the present invention, costs due to the optical line extension can be reduced by not requiring an additional optical line for a heterogeneous network service; convenience can be provided by utilizing handover between different services when a handover between heterogeneous networks occurs due to a movement from one network zone to the other network zone, which is caused by sharing an optical line; and an installation space for the distributed communications system can be efficiently used by not requiring existing additional equipment such as a matching apparatus for a heterogeneous network service. |
