Abstract:
본 발명은 적응적 버퍼 관리 방법에 관한 것으로서, 더 상세하게는 음성 트래픽의 중요도를 고려하여 음성 서비스를 용량 증가시키는 적응적 버퍼 관리 방법에 대한 것이다. 본 발명에 따르면, 사용자의 음성 정보를 저장하고 있는 음성 패킷의 전달 성공 확률을 증가시키고 음성 패킷이 종단 간에 전달되는 시간을 단축시켜 사용자 측면의 음성 서비스 품질을 증가시킬 뿐만 아니라 망의 음성 서비스 용량을 증가시키는 효과를 가진다.
Abstract:
The present invention relates to an adaptive buffer management method and, more specifically, to an adaptive buffer management method in consideration of the importance of a voice traffic to increase capacity of voice services. According to the present invention, the method increases the transmission success rate of a voice packet containing voice information of a user, increases the quality of voice services on the user side by reducing the time needed for the voice packet to be transferred end-to-end, and also increases the capacity of the voice services in a network.
Abstract:
PURPOSE: An X band frequency formation apparatus and method are provided to reduce the unnecessary noise of a communications system by suppressing unnecessary signals among doubled signals within the band. CONSTITUTION: An X band frequency formation apparatus comprises a frequency scaler (30), a frequency amplifier (40) and a band divider (50). The frequency scaler generates individual doubled frequency which is multiplied to n times from reference frequency. The frequency scaler forms the output unit and circuit of the frequency scaler in order to amplify the relatively low output state of the individual doubled frequency while suppressing noise. The band divider forms the output unit and circuit of the frequency scaler and transmits each doubled frequency which comes out of the frequency scaler in accordance with a necessary output signal.
