Abstract:
A pilot signal strength adjusting method in a mobile communication system comprising the steps of:checking total number of calls allocated to a current reference frequency of a base station which is installed with a CPTU Common Pilot Transmit Unit, or calls of mobile stations concentrated on a reference frequency of the base station which is installed with the CPTU Common Pilot Transmit Unit, and comparing the total number of calls to a predetermined threshold value of set-up calls when either a call set-up or a call release is requested by the mobile station; adjusting strength of a pilot signal by increasing and/or decreasing power of a CPCA Common Pilot Control Assembly installed in the CPTU Common Pilot Transmit Unit; and using a total number of calls which are located to reference frequencies of the base station so that hard handoff to different frequencies may be performed smoothly between adjacent base stations, if the call release is performed by the user unit basis.
