Abstract: 셀룰러 시스템에서 순방향 전력 제어 방법에 대하여 개시한다. 본 방법은, 무선 링크를 통해 이동 전화기와 연결되는 기지국을 포함하는 셀룰러 시스템에 있어서, 기지국은 이동 전화기로부터 기지국에서 이동 전화기의 방향으로 형성되는 순방향 링크의 품질에 대한 정보를 주기적으로 수신하여, 순방향 링크의 송신 전력을 제어한다. 순방향 링크의 품질이 악화되어 한 주기가 지나도록 이동 전화기로부터 순방향 링크 품질에 대한 정보를 얻지 못하게 되면, 기지국은 순방향 링크의 전력 제어 파라미터를 변경하여, 악화된 순방향 링크의 환경에 대처한다. 기지국은 시스템의 용량을 고려하여, 기존의 송신 전력을 제어하는 과정에서보다, 순방향 링크의 송신 전력을 빠르게 감소시킨다.

Abstract: PURPOSE: The method for analyzing voice activity of the CDMA(Code Division Multiple Access) mobile communication system is provided to measure the voice activity through probability related to transmission speeds per frame of voice data, and to measure exact voice activity, so as to correctly measure a system capacity of the CDMA mobile communication system. CONSTITUTION: If a test terminal(150) senses a call request for a voice activity examination from a user(213), in a state of the test terminal(150) being interfaced through a cable(211), the test terminal(150) performs a call setup through a CDMA(Code Division Multiple Access) mobile communication system(215). The test terminal(150) intends to analyze voice activity with an operator terminal(100). If a set call is connected to other party(217), the operator terminal(100) collects transmission speed data per frame of voice data from the moment when the call is connected(219). The voice data is transceived through the test terminal(150). The operator terminal(100) continues to collect the data, and performs a probability conversion for the transmission speed data(223), until a preset time elapses(221). The operator terminal(100) calculates the voice activity with the probability conversion-performed data. The operator terminal(100) displays the calculated voice activity and returns(227).

Abstract: PURPOSE: An arrangement and a method for constructing a zone database for a homezone service are provided to construct simply and correctly a homezone database by dividing the region in which a homezone service is executed. CONSTITUTION: A region in which a homezone service is executed is divided into spots(3a). Variable n is set to 1(3b). A coverage simulation is performed for the first spot, and then the intensity of pilot signals received from base stations around the above spot are measured(3c). The measured intensity of pilot signals are sorted in order of intensity(3d). From the greatest, the predetermined number of base stations are selected in order to intensity(3e). The zone database is constructed by choosing the selected base stations as homezone of the corresponding spot(3f). It is tested that databases for all the spots are constructed(3g). If not, variable n is increased by one, and then the above processes 3c-3f continue.

Abstract: PURPOSE: A method for determining a subscriber home zone region for home zone service is provided to enable to determine the subscriber home zone region effectively by allowing a subscriber to determine the subscriber home zone region freely. CONSTITUTION: A home zone region in which a subscriber want to register is temporarily indicated on a coordinate map(3a). Points(edges) of which horizontal boundary lines and vertical boundary lines in the temporary home zone region are crossed on the coordinate map each other are indicated(3b). Latitudes and longitudes for the above crossing points are measured by GPS receiver(3c). A latitude and longitude for a bin which includes each crossing point is determined by a latitude and longitude of the corresponding crossing point(3d). By making definite straight lines for linking between bins which a latitude and longitude have been determined, a closed curved surface is formed, where the entire inside of this closed curved surface becomes the home zone region of the corresponding subscriber(3e). All bins in the above closed curved surface are selected(3f). A home zone region is determined by synthesizing the information for sector lists of the above selected bins(3g).
