Disclosed is a method of accommodating wireless base stations, comprising: a step A in which a network apparatus (100) manages a set of parameters including at least a single parameter value in each group area; a step B in which, when the position of arrangement of a wireless base station (200) has been determined, the network apparatus (100) selects one set of parameters from the set of parameters for the group area including the arrangement position of the wireless base station (200) and allocates this set to the wireless base station (200); and a step C in which, after the wireless base station (200) has been connected with the network apparatus (100), an operation is conducted using a parameter value included in the parameter set that has been allocated.
