Abstract:
1. A communication device for adjusting a service area of a mobile communication to a mobile station in a predetermined communication area including a plurality of base stations that adjust a transmission-parameter, the communication device comprising: a data acquiring unit that acquires an index value indicating downstream reception quality of a mobile station in the predetermined communication area from the mobile station via a base station in the predetermined communication area with respect to each mobile station; and a determining unit that determines whether to start or end an execution of arithmetic processing of a transmission parameter of each base station in the communication area by comparing a value based on at least any of a communication quality between the base station and the mobile station in the communication area, throughput, and received power, which is obtained based on the index value of each mobile station that include said mobile station, with a reference value, wherein the execution of the arithmetic processing comprises adjusting the service area to the mobile station in the predetermined communication area that includes the plurality of base stations, wherein the determining unit applies a start of an execution of optimization algorithm on a condition that an average reception quality of mobile stations in the predetermined communication area has deteriorated to below the reference value; and applies an end of the execution of the optimization algorithm on a condition that the average reception quality of the mobile stations in the predetermined communication area has become equal to or higher than the reference value and a reception quality has been improved so as to determine whether to start or end the execution of the arithmetic processing by using the optimization algorithm.
