摘要： A frequency control assist device is configured to: calculate an average value of pulse numbers each of which is a pulse number of a reference signal generated by an oscillator in one cycle of a PPS signal generated based on a GPS signal, from a total of the pulse numbers counted for a time period whose length is a predetermined number times the one cycle, the average value being an average value of the pulse numbers each for the one cycle; and every time a deviation between a specified value of a reference frequency of the reference signal and the average value falls below a target value, reduce the target value from the current value and increase, from the current value, the predetermined number that specifies the time period for obtaining the total of the pulse numbers from which the average value is to be calculated by an averaging circuit.

摘要： A gateway device (30) relays voice communication between a communication terminal to be connected to a closed network (10) and a communication terminal to be connected to a LAN (20). The gateway device (30) includes a closed network communicator (31) connected to the closed network (10), a communication relay (32) to perform encapsulation or decapsulation of data for enabling voice communication between the closed network (10) and the LAN (20), and a LAN communicator (33) connected to the LAN (20).

摘要： [Problem] Provided is a relaying device that can track and record a communicated voice of a specific communication terminal using a mixing function of the relaying device.
[Solution] When a communication terminal has made a call, a communication session in which the communication terminal that has made a call and a communication terminal that has been called are participating terminals is established. When a voice signal is transmitted from one participating terminal of the established communication session, this voice signal is transmitted to the other participating terminal(s) of the same communication session along with session information. A virtual device is associated with a communication terminal, and is registered in a communication session in which the communication terminal participates as a participating terminal together with the communication terminal. A communication monitoring unit records a voice signal transmitted to the virtual device from the communication session.

摘要： Provided is a method for, upon transmission of a DSC message being instructed, enabling quick start of the transmission. The method includes; (1) instructing, upon transmission of the DSC message being instructed, an antenna tuner to start tuning regardless of whether being busy or not, and switching an antenna from reception to transmission after the tuning is completed, (2) performing busy check, and standing by for a time period defined in the standard, when a reception signal in a transmission channel is no longer a dot pattern, and executing these processes (1) and (2) in parallel.

摘要： An angle calculator calculates, based on acceleration detected by an acceleration sensor, a tilt angle of a transceiver with respect to the vertical direction. A selector (i) selects a first audio filter to operate if the tilt angle is less than a threshold angle, or (ii) selects a second audio filter to operate if the tilt angle is equal to or greater than the threshold angle. The second audio filter has a lower cutoff frequency that is higher than the lower cutoff frequency of the first audio filter.
