A central management server for special communication may include: a spectrum sensing information acquisition unit for acquiring spectrum sensing information from spectrum sensing servers; an OP map generation unit for generating an OP value for each channel if there is an access request from a second layer; and a channel allocation unit configured to allocate a channel based on the OP value to a user terminal of the second layer requesting access if there is an access request from the second layer. The channel allocation unit may allocate a channel corresponding to the highest OP value from among the available channels, if there are available channels unused by both a first layer and a lower-level layer, and may select and allocate a channel unused by the first layer but used by the lower-level layer, if there are no such available channels.
