The invention provides an interference coordination method and a server. According to the interference coordination method and the server, a message for indicating a second server to reduce same frequency interference with a first server is transmitted when a preset trigger condition is satisfied through monitoring, namely, when determining that a train carrying user equipment is passing through a cell covered by the first server, the problem of same frequency interference between the first server and the second server in the prior art is solved without influencing network traffic of a cell covered by the second server, and the throughput capacity of the first server is improved. The interference coordination method comprises the steps of: generating a message used for limiting frequency usage of overlapping portions occupied by the first server and the second server when the amount of user terminal in the cell covered by the first server reaches a preset threshold value; and transmitting the generated message to the second server.
