  • Patent number: 11399239
    Abstract: An audio calibration system applied to a hearing detection device includes an audio generator, a cloud server, a mobile computing device, and an audio playback unit. The audio generator plays a first test sound. A sound pressure level of the first test sound at any frequency between 500 Hz and 4000 Hz is Z. A computing unit of the mobile computing device generates a first value X after receiving the first test sound through a microphone, and the computing unit generates a second value Y after receiving a second test sound through the microphone. The audio playback unit receives an audio command from an audio control interface, and plays the second test sound to the microphone. The computing unit obtains a calibration value through a relational expression of Z+(Y?X).

  • Publication number: 20210321203
    Abstract: A hearing compensation module disposed in a voice service module includes a control unit, a voice receiving unit, a voice playback unit, a storage unit, and an identity recognition module. The storage unit stores a hearing compensation datum corresponding to a user. The identity recognition module adjusts an access authority of the control unit to the hearing compensation datum. The voice receiving unit receives a first voice message through the user. The control unit converts the first voice message into a second voice message according to the hearing compensation datum. The voice playback unit plays the second voice message to the user.

  • Patent number: 8432991
    Abstract: A measurement processing method is provided. The method includes performing physical layer filtering on measurement sample data obtained in measurement to obtain measurement values. Time-frequency domain normalization filtering may be performed on the obtained measurement values to obtain a measurement result, which, in turn may be evaluated. A measurement processing apparatus is further provided. The measurement processing solutions solve problems in the prior art such as that time domain and frequency domain characteristics of the measurement values are not considered when Layer 3 filtering is performed, and that the system must process more measurement sample data if Layer 3 filtering is not used. In the solutions, time-frequency domain normalization filtering is performed on the measurement values obtained after physical layer filtering to obtain a final measurement result, so that a more accurate measurement result is obtained, thus optimizing the network performance.

  • Patent number: 8233403
    Abstract: The invention provides a method and an element for determining a measurement time of an inter-frequency measurement, used for the dual mode UE supporting FDD mode and TDD mode in the FDD mode to perform the inter-frequency measurement to the TDD cell. If a whole timeslot is found within the measurement time, the PCCPCH mapped from the broadcast channel bearing the system information being located in the timeslot, the measurement time is taken as the valid measurement time for measuring the measurement performance. Accordingly, a method for measuring inter-frequency is also provided. A credible valid measurement time and a credible inter-frequency measurement may be realized according to the invention. Thus, the accuracy for evaluating the measurement performance and the measurement accuracy may be improved.

  • Patent number: 8111628
    Abstract: A method for measuring Inter-Frequency/Inter-RAT (Radio Access Technology) in Multimedia Broadcast/Multicast Service (MBMS) includes: setting an Inter-Frequency/Inter-RAT measurement time to prevent Inter-Frequency/Inter-RAT measurement time from overlapping constantly the transmission time of MCCH information; performing Inter-Frequency/Inter-RAT measurement by a UE according to the Inter-Frequency/Inter-RAT measurement time. In the present invention, the Inter-Frequency/Inter-RAT measurement time can be prevented from overlapping constantly the time when UTRAN transmits the MCCH information, so that the problem that the UE cannot receive MCCH information during Inter-Frequency/Inter-RAT measurement time may be solved. In the invention, a measurement time setting device is also provided for implementing Inter-Frequency/Inter-RAT measurement in Multimedia Broadcast/Multicast Service.
