A base station management system , comprising: a base station management device , managing a plurality of base stations (120-1, 120-2, 120-3); and a first base station (120-1), sending a first link request to the base station management device based on a default port number and a base station management device address through a communication interface , wherein after the base station management device receives the first link request, the base station management device establishes a link with the first base station (120-1) based on the first link request, and changes a port number corresponding to the first base station (120-1) from the default number to an unused first port number to release the default port number, wherein the first base station (120-1) establishes the link with the base station management device again based on the first port number, wherein after the base station management device changes the port number corresponding to the first base station (120-1) from the default number to the first port number, the base station management device terminates the link with the first base station (120-1), wherein after the base station management device terminates the link with the first base station (120-1), the first base station (120-1) sends the first link request to the base station management device again based on the first port number and the base station management device address through the communication interface , and after the base station management device receives the first link request again, the base station management device establishes the link with the first base station (120-1) again based on the first link request. a base station management device , managing a plurality of base stations (120-1, 120-2, 120-3); and a first base station (120-1), sending a first link request to the base station management device based on a default port number and a base station management device address through a communication interface , wherein after the base station management device receives the first link request, the base station management device establishes a link with the first base station (120-1) based on the first link request, and changes a port number corresponding to the first base station (120-1) from the default number to an unused first port number to release the default port number, wherein the first base station (120-1) establishes the link with the base station management device again based on the first port number, wherein after the base station management device changes the port number corresponding to the first base station (120-1) from the default number to the first port number, the base station management device terminates the link with the first base station (120-1), wherein after the base station management device terminates the link with the first base station (120-1), the first base station (120-1) sends the first link request to the base station management device again based on the first port number and the base station management device address through the communication interface , and after the base station management device receives the first link request again, the base station management device establishes the link with the first base station (120-1) again based on the first link request. <EOS>
