Patent ID: 7088960

Claim:
A wireless channel setting method for a mobile communication system in which a common channel, which all mobile stations are permitted to use for signal exchange at the start of communication, and an individual channel, which is tuned through the setting process for each mobile station, are switched so as to be used as a wireless channel between a mobile station and a wireless base station, the method comprising the steps of: receiving, at the wireless base station a transmission signal from a specific mobile station through the common channel; and sequentially comparing, to a respective corresponding predetermined threshold value, a transmission power value to transmit to the mobile station, a communication quality level to transmit with a mobile station, and a utilization ratio of the common channel, wherein when the transmission power value, the communication quality level and utilization ratio are lower than the respective corresponding predetermined threshold values, the wireless base station continues the signal transmission/reception, through the common channel, with the specific mobile station, and when any of the sequentially compared transmission power value communication quality level, and utilization ratio exceed the respective corresponding predetermined threshold value, the wireless base station sets said individual channel and continues signal transmission/reception, through the individual channel, with the specific mobile station.
