Wireless parameter control apparatus, wireless base station, wireless communication system, wireless parameter control method, and program

A wireless parameter control method for a wireless parameter control apparatus in a wireless communication system in which a wireless cell which is connected to by a wireless terminal can be controlled by adding an offset value to a wireless quality of each wireless cell measured by the wireless terminal, comprising:

• predicting a wireless cell which is connected to by a first wireless terminal in a first wireless cell upon assuming that an offset value to be added to a wireless quality of each wireless cell measured by the first wireless terminal is changed to a predetermined candidate value;
• predicting at least one communication speed index of a communication speed index of the first wireless terminal and a communication speed index of a second wireless terminal in a second wireless cell existing around the first wireless cell upon assuming that the offset value is changed to the predetermined candidate value;
• and
• controlling at least one coverage of coverage of the first wireless cell and coverage of the second wireless cell based on a prediction result of the communication speed index, wherein
• a wireless cell which is connected to by the first wireless terminal upon assuming that the offset value is changed to the predetermined candidate value is predicted using a value resulting from adding the candidate value to a measurement result of a wireless quality of each wireless cell measured by the first wireless terminal, and
• the at least one communication speed index upon assuming that the offset value is changed to the predetermined candidate value is predicted without adding the candidate value to a measurement result of a wireless quality of each wireless cell measured by the first wireless terminal or the second wireless terminal.

A non-transitory recording medium which records a program for a wireless parameter control apparatus in a wireless communication system in which a wireless cell which is connected to by a wireless terminal can be controlled by adding an offset value to a wireless quality of each wireless cell measured by the wireless terminal, the program making a computer as a wireless parameter control apparatus execute:

• a process of predicting a wireless cell which is connected to by a first wireless terminal in a first wireless cell upon assuming that an offset value to be added to a wireless quality of each wireless cell measured by the first wireless terminal is changed to a predetermined candidate value;
• a process of predicting at least one communication speed index of a communication speed index of the first wireless terminal and a communication speed index of a second wireless terminal in a second wireless cell existing around the first wireless cell upon assuming that the offset value is changed to the predetermined candidate value;
• and
• a process of controlling at least one coverage of coverage of the first wireless cell and coverage of the second wireless cell based on a prediction result of the communication speed index, wherein
• a wireless cell which is connected to by the first wireless terminal upon assuming that the offset value is changed to the predetermined candidate value is predicted using a value resulting from adding the candidate value to a measurement result of a wireless quality of each wireless cell measured by the first wireless terminal, and
• the at least one communication speed index upon assuming that the offset value is changed to the predetermined candidate value is predicted without adding the candidate value to a measurement result of a wireless quality of each wireless cell measured by the first wireless terminal or the second wireless terminal.
