Claim:
1. A method of measuring communication quality, comprising: setting two or more measurement-time slots with respect to a communication line used for communication quality measurements in communication with two or more communication terminal apparatuses via a mobile communication network, each of the two or more measurement-time slots having a time corresponding to one measurement of communication quality, and the two or more measurement-time slots being continuously arranged at a predetermined period; assigning two or more measurement schedules for measuring communication quality in each of communications with the two or more communication terminal apparatuses to the two or more measurement-time slots; delivering information of the measurement schedule for each of the two or more communication terminal apparatuses to each of the communication terminal apparatuses; performing a communication for the communication quality measurement with the communication terminal apparatus corresponding to the measurement schedule via the communication line when the time of measurement schedule comes; presetting a measurement-time slot for re-assigning the measurement schedule to a part of the forgoing two or more measurement-time slots; re-assigning the measurement schedule for the communication terminal apparatus to the measurement-time slot for re-assigning when the delivery of the measurement schedule information is failed without delivering the measurement schedule information to the communication terminal apparatus by the time of measurement schedule; and delivering information of the re-assigned measurement schedule to the communication terminal apparatus to which the measurement schedule information is failed to deliver.
