Abstract

본 발명은 이동전화서비스를 위한 코드분할 다원접속(Code Division Multiple Access)셀룰라시스템과 이동위성통신 시스템에 대하여 하나의 단말기를이용 두시스템을 이용할 수 있게 하는 이중모드 단말기 서비스 시스템의 접속방법에 관한 것으로서 자동선택 방식과 임의 선택방식으로 구분되어 자동선택 방식인 경우 각 시스템의 서비스신호 세기를 측정하여 이동위성시스템의 신호가 코드분할 다원접속 셀룰라 시스템으로 통신 서비스를 제공하며 임의 선택방식인 경우 선택된 시스템의 서비스를 제공하되 만약 선택된 시스템의 신호가 설정치 이하인 경우 다른 시스템의 신호세기를 측정하여 신호세기가 서비스가 가능한 시스템으로 통신서비스를 제공하는 이중모드 단말기로 통신서비스 시스템을 접속하는 방법이다.The present invention relates to a method of accessing a dual mode terminal service system that enables two systems using one terminal for a code division multiple access cellular system and a mobile satellite communication system. In the case of the automatic selection method, the service signal strength of each system is measured in the case of the automatic selection method, and the signal of the mobile satellite system provides the communication service to the code division multiple access cellular system. If the signal of the selected system is provided below the set value, but the service is provided by measuring the signal strength of the other system is a method of accessing the communication service system to a dual-mode terminal that provides a communication service to the system capable of serving the signal strength.
