LTE-M system based on distributed core network

The utility model provides an LTE-M (Long Term Evolution-Media) system based on a distributed core network. The LTE-M system comprises a central core network, a DCS (Distributed Control System) wired ring network and at least one distributed core network, the central core network is deployed in the control center subsystem and is in communication connection with the train operation control system; the DCS wired looped network is deployed in the trackside subsystem and is in communication connection with the central core network; the at least one distributed core network is deployed in the trackside subsystem and is in communication connection with the DCS wired looped network and the train operation control system; and data interaction between the train operation control system and the trackside subsystem is realized through the central core network, the DCS wired looped network and the distributed core network. According to the utility model, by adopting a mode of deploying the distributed core network in th
