摘要： A method for accurately measuring the quality of UDP data when uplinking the UDP data through a mobile communication terminal is provided. A UDP client transmits a UDP uplink scenario which is set up by a user through a mobile communication terminal to a UDP(S10). In case the UDP client receives a response message permitting the UDP uplink scenario from the UDP server, it generates UDP packets as much as the packet size set by the UDP uplink scenario, and then records sequence number and packet size on the generated packets(S12, S16, S18). The UDP client uplinks the completed UDP packets through the mobile communication terminal to the UDP server(S20), and then receives/stores/displays the transmission quality which the UDP server measures(S24).

摘要： An automatic volume level controlling method for MOS(Mean Opinion Score) measurement is provided to be capable of automatically controlling the level of substantial speech volume to a predetermined optimum level before speech quality is measured, thus reliability of an MOS value is improved. When an audio signal having a predetermined type is received as including a speech signal from an MOS measurement equipment of the other party, the speech signal is compared with a reference volume level by measuring volume level of the speech signal(S10-S20). An intrinsic audio frequency signal predetermined according to information indicative of 'proper', 'too much' or 'insufficient' in accordance with the compared results is transmitted to the MOS measurement equipment of the other party(S22-S32). The MOS measurement equipment decodes the intrinsic audio frequency signal, and controls the volume level(S34-S50).

摘要： A time synchronizing method for MOS(Mean Opinion Score) measurement devices is provided to be capable of synchronizing MOS measurement times between an MOS measurement device which is in an environment where a standard time can be obtained and an MOS measurement device unable to obtain the standard time, thus reliability on MOS measurement values is increased. In a state of a channel being open, an MOS measurement device for standard time transmits an MOS measurement audio signal, consisting of a speech signal and a count tone signal indicative of a value obtained by counting the number of times the speech signal is transmitted, to an MOS measurement device for non-standard time(S10-S30). The MOS measurement device for the non-standard time measures an MOS value by the speech signal, and stores the measured value together with the counting value included in the audio signal(S40,S42). The MOS measurement device for the standard time generates a table, where the counting value and an audio transmission time are matched, and sends the table to the MOS measurement device for the non-standard time(S32-S52). The MOS measurement device for the non-standard time extracts the transmission time matched with the counting value from the table, and matches the extracted time with an equivalent MOS measurement value(S54).

摘要： A method for remotely controlling an MOS(Mean Opinion Score) measurement equipment is provided to enable a tester to remotely control a synchronization task such as selection/setup functions for a measurement equipment of a called party without directly visiting a place where the measurement equipment is installed, thus the manpower and time required for MOS measurement are reduced. A self side MOS measurement equipment receives various MOS measurement selection/setup values related to an MOS measurement equipment of the other party from a tester, and stores the received values(S10-S16). The self side equipment attempts a call with the MOS measurement equipment of the other party(S18). If a speech path is open, the self side equipment converts the selection/setup values into audio frequency signals allocated to be previously divided, and sends the converted signals to the MOS measurement equipment of the other party(S20-S30). The MOS measurement equipment of the other party receives the signals to confirm the selection/setup values, and conducts required control(S32).
