Abstract: Methods and systems of measuring communication quality in a communication via a mobile communication network are provided. A connection status of a communication terminal apparatus to a mobile communication network is confirmed when a timing of transmitting a measurement data of the communication terminal apparatus side from the communication terminal apparatus to a server comes. The measurement data is transmitted from the communication apparatus to the server when determining that it is a status capable of transceiving the measurement data, based on the confirmation result of connection status, and the measurement data is not transmitted from the communication terminal apparatus to the server when determining it is not a status capable of transceiving the measurement data. A communication quality in the communication via the mobile communication network is measured based on the measurement data received by the server from the communication terminal apparatus.

Abstract: Methods and systems of measuring communication quality are provided, by which measurement schedules of communication quality can be managed and controlled easily. A plural measurement-time slot is set with respect to a communication line used for communication quality measurements between a plural communication terminal apparatus via a mobile communication network, wherein each measurement-time slot has a time corresponding to one measurement of communication quality and the plural measurement-time slot is continuously arranged at a predetermined period, and a plural measurement schedule for measuring communication quality in each of communications with the plural communication terminal apparatus to the plural measurement-time slot. Information of the measurement schedule for each of the plural communication terminal apparatus is delivered to each communication terminal apparatus, and a communication for the communication quality measurement with the communication terminal apparatus corresponding to the measurement schedule via the communication line is performed when the time of measurement schedule comes.

Abstract: Communication systems and communication methods capable of evaluating a voice quality in a voice communication of a communication network and a presence or absence of a call drop of the voice communication are provided. A voice communication of transceiving a test signal for voice communication quality evaluation between a communication terminal apparatus 100 and a voice communication evaluation system 400 via the communication network 300 is performed. A voice quality evaluation value is calculated based on the test signal before transmission and the test signal after reception in the voice communication. A presence or absence of a call drop of the voice communication is determined based on a presence or absence of reception interruption of the test signal.

Abstract: Methods and systems of measuring communication quality are provided, by which various types of communication quality measurements can be flexibly performed as the measurement condition can be set or changed easily and optionally, while load of processing in the communication terminal apparatus can be suppressed. Measurement condition for measuring communication quality is delivered to a communication terminal apparatus capable of communicating via a mobile communication network and a communication with the communication terminal apparatus via the mobile communication network is performed at a predetermined timing that satisfies the measurement condition. Then, at least one of terminal-side measurement data including terminal-status log information and network-side measurement data including terminal-existing base-station quality information corresponding to communication corresponding to the predetermined timing which are recorded in the communication terminal apparatus is acquired, and an index value of communication quality in communication via the mobile communication network is calculated based on at least one of the terminal-side measurement data and the network-side measurement data.

Abstract: Communication systems and communication methods are provided, by which load of a communication network when measuring a voice communication quality can be suppressed. A test signal for voice communication quality evaluation is transmitted to a communication terminal apparatus via a communication network, and a received voice data encoded by a predetermined scheme for the test signal received with the communication terminal apparatus is received from the communication terminal apparatus. A received voice signal is generated from the received voice data received from the communication terminal apparatus, and a evaluation value of voice communication quality is calculated by comparing the generated received voice signal with the test signal before transmitting.
