ABSTRACT:
A cell searching apparatus and method in an asynchronous mobile communication system allocates an adjacent SCG to each base station according to adjacent degrees. When a mobile terminal is powered on, the mobile terminal receives PSCs and SSCs from the base stations. Multiple searching of SSCs is then performed based on each slot synchronization followed by a frame synchronization and SCG detection through the first searched SSC. If the detected SCG is not an SCG of a base station to which the mobile terminal belongs, the cell searching apparatus detects an SCG with a large size among the adjacent SCGs and detects an SC by using the greatest SCG. Frame synchronization and SCG detection are therefore quickly performed in a cell searching, resulting in a quick search searching.
