Abstract

본 발명은 이동통신 기술분야에 있어서, 음성데이타를 패킷형태로 전송하는 이동통신망에서의 패킷처리방식에 관한 것으로, 이동국의 음성정보 패킷타이징(Packetizing)에서 발생하는 전송지연의 극복 및 기지국에서 다중채널의 비동기 음성 패킷을 동기화 시키는데 소요되는 지연을 극복함으로서 이동가입자 상호간 또는 고정가입자와 이동가입자의 통신상에서의 반향을 감소하도록 된 디지틀 이동통신망에서 음성 패킷 지연 극복 방법을 제공하는데 그 목적이 있고, 상기 목적을 달성하기 위해 이동국의 실시간 패킷전송과 기지국의 다중채널에서 패킷을 파일롯 채널에 동기시켜 패킷 재배치를 수행하도록 하여 파일롯 동기에 맞추어 동시 진행되며 패킷동기가 이루어진 후 전송은 저장 및 전송과정이 아닌 실시간 전송이 이루어지므로 패킷형 음성 데이타 교환 및 전송에 기인하는 지연과 패킷타이징에 따른 지연을 제거하는 것을 주요 기능으로 하고 있다.BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a packet processing method in a mobile communication network that transmits voice data in the form of a packet in the field of mobile communication technology, and overcomes the transmission delay occurring in the packetizing of voice information of a mobile station and It is an object of the present invention to provide a method for overcoming voice packet delay in a digital mobile communication network which is configured to reduce echoes between mobile subscribers or between fixed subscribers and mobile subscribers by overcoming delays required to synchronize asynchronous voice packets of a channel. In order to achieve the objective, real-time packet transmission of the mobile station and packet relocation are performed in synchronization with the pilot channel in the multi-channel of the base station. Because the transmission takes place, The main function is to eliminate the delay due to the exchange and transmission and the delay due to packetizing.
