Abstract

There is provided a method of transmitting data between compact control stations using the Ethernet, including a network matching unit generation steps of separately generating the function of a network matching unit of each compact control station according to a data transmission function and data reception function, a data reception step of, when the network matching unit of one of the compact control stations is generated to have the data reception function at the network matching unit generation step, receiving operation maintenance data from the network matching unit of the other compact control station through TCP/IP communication using the Ethernet, and a data transmission step, when the network matching unit of one of the compact control stations is generated to have the data transmission function at the network matching unit generation step, transmitting control data and the operation maintenance data to the network matching unit of the other compact control station through TCP/IP communication using the Ethernet. The invention can perform TCP/IP communication using the Ethernet between the compact control stations having the BSM function and control station function to accurately transmit and receive the operation maintenance data without affecting call processing data between the compact control stations. The invention does not use an expensive network matching apparatus to lighten economic burden. Moreover, TCP/IP communication allows retransmission of data when there is data loss during communication so that accuracy in the transmission of the maintenance data can be guaranteed.
