Abstract

본 발명은 디지틀 이동통신망에서 호의 형태에 따라 적응적으로 동작하는 음성 부호화기의 적응적 동작 방법에 관한 것으로, 호의 형태를 설정하고 설정된 호의 정보를 메모리에 저장하는 호의 형태 결정단계(11,12,13), 상기 저장된 호의 정보가 이동국-랜드호, 및 랜드-이동국 호를 나타내는 경우 정상적인 보코딩(Vocoding)모드로 동작시키는 보코딩 모드 동작 단계(14,15) 및 상기 설정된 호가 이동국-이동국인 경우 프리앰블(Preamble) 체크바이트를 추가한 인코디드 패킷을 바이패스모드로 동작시키는 바이패스모드 동작단계(16)에 의해 수행된다. 따라서 본 발명은 이동국-이동국 호의 경우 단말기와 시스템에서의 더블 보코딩으로 인한 음성 품질의 저하 방지 및 MIPS 감소로 인한 전력 소모의 감소 효과를 기대할 수 있어 이동 통신망의 성능을 향상시키는 효과가 있다.The present invention relates to an adaptive operation method of a speech coder that is adaptively operated according to the type of a call in a digital mobile communication network. The method of determining the type of a call and storing the set call information in a memory (11, 12, 13) Vocoding mode operation steps 14 and 15 for operating in a normal vocoding mode when the stored call information indicates a mobile station-land call and a land-mobile station call, and a preamble when the set call is a mobile station mobile station. (Preamble) This is performed by the bypass mode operation step 16 of operating an encoded packet including the check byte in the bypass mode. Accordingly, the present invention can be expected to prevent the degradation of the voice quality due to the double vocoding in the terminal and system, and to reduce the power consumption due to the reduction of MIPS in the case of the mobile station-mobile station call, thereby improving the performance of the mobile communication network.
