ABSTRACT:
A method for setting up perch channels in a mobile communication by a cellular system, capable of setting up a perch channel and a perch channel list for surrounding base stations at each newly provided base station autonomously. At the newly provided base station, reception levels of signals transmitted by mobile stations to surrounding base stations are measured by scanning uplink control channels corresponding to perch channels, and a perch channel of the newly provided base station and a perch channel list to be signaled by the newly provided base station are autonomously set according to the measured reception levels. Alternatively, reception levels of signals transmitted through perch channels by surrounding base stations are measured while receiving perch channel lists signaled by the surrounding base stations, and a perch channel of the newly provided base station and a perch channel list to be signaled by the newly provided base station are autonomously set according to the measured reception levels and the received perch channel lists of the surrounding base stations.
