    • The position of a mobile station is properly monitored and is stored in a home location register. A call which indicates this mobile station as a calling/receiving station is set via any mobile service switching center. When monitoring a communication oriented by this call is necessary, the subscriber number of this mobile station is input by a test work station. Based on this subscriber number, an operation and maintenance center reads position data of the mobile station from the home location register and reports the data to the test work station. Based on the position data, the test work station specifies the mobile service switching center through which the call has been set, and transfer data specifying this mobile service switching center to the operation and maintenance center. The operation and maintenance center extracts the call-oriented voices from this mobile service switching center.

    • A traffic management system with overload control functions which deals with traffic congestion happened in a particular coverage area as part of a telecommunications network system. The traffic management system comprises two main units: an overload controller and a call restriction processor. The overload controller identifies the coverage area in a high-traffic condition and activates the call restriction processor deployed in the identified area. Under the control of the overload controller, the call restriction processor regulates the acceptance of calls from subscribers within the area. To provide such overload control functions, the overload controller comprises the following processors. An originating call analysis processor analyzes each originating call to locate the coverage area where the call setup request was initiated. A call-restricted area search processor determines whether to designate the originating coverage area as a call-restricted coverage area which is subject to call restriction. A restriction control message processor sends a restriction control message that specifies an operation to be executed by the call restriction processor.

    • A frequency detection circuit detects the frequency of a horizontal sync signal, and generates a mode switching signal corresponding to the detected frequency. A voltage-controlled oscillator constituting a PLL circuit has a plurality of oscillation modes obtained by dividing a frequency equal to an integer multiple of the frequency of the horizontal sync signal into a plurality of frequency ranges, and oscillates signals in the respective frequency ranges in accordance with control voltages output from a filter. The oscillation modes of the voltage-controlled oscillator are switched in accordance with the mode switching signal output from the frequency detection circuit. In the voltage-controlled oscillator, since the frequency range in each oscillation mode is narrow, the oscillation gain can be suppressed low, and a deterioration in jitter characteristics can be prevented.
