A base station apparatus in a wireless communication system and a method for acquiring load information are provided that make it possible to acquire load information per operator, without changing the standardized interface specifications. In a wireless communication system including base stations (10, 20) each capable of supporting a predetermined number of, or fewer, network operators (A, B, C, D), the first base station (10) retains identification information of network operators supported in a neighbor cell that is managed by the second base station (20) (S30); the first base station (10) sends a load information request message based on the identification information of the operators in the neighbor cell (S32); the second base station (20), in response to the load information request message, sets load information of a network operator or network operators supported in the neighbor cell in a load information notification message and sends it (S33, S34); and the first base station (10) acquires the load information per operator of the neighbor cell from the load information notification message (S35). |
