Wireless channel setting method for mobile communication system and mobile communication control apparatus

A wireless channel setting method for a mobile communication system between the mobile station and the wireless base station in which a common channel, which every mobile station is 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 obtain a wireless channel for use by a mobile station and a wireless base station, the method comprising the steps of:

• (a) the wireless base station receives a transmission signal from a specific mobile station through the common channel, and compares the communication quality level to transmit with the mobile station with the predetermined threshold;
• (b) when the communication quality level is lower than the predetermined threshold value, the wireless base station continues the signal transmission/reception, through the common channel, with the specific mobile station;
• and
• (c) when the communication quality level exceeds the predetermined threshold value, the wireless base station sets an individual channel and continues the signal transmission/reception, through the individual channel, with the specific mobile station.

• (a) the base wireless station receives a signal from a specific mobile station through the common channel, and compares a utilization ratio of the common channel with a predetermined threshold value;
• (b) when the utilization ratio of the common channel is lower than the predetermined threshold value, the base wireless station continues the signal transmission/reception, through the common channel, with the specific mobile station;
• and
• (c) when the utilization ratio of the common channel exceeds the predetermined threshold value, the wireless base station sets an individual channel and continues the signal transmission/reception, through the individual channel, with the specific mobile station.

A mobile communication apparatus comprising:

• a control signal processor for setting and switching wireless signals in accordance with a received instruction;
• a wireless channel setting controller for determining which wireless channel is to be used by each mobile station based on a notified transmission power over the common channel, and for instructing the wireless channel to be used to the control signal processor;
• and
• a transmission power measuring unit for measuring the transmission power value over the wireless channel for each mobile station, and for notifying the transmission power value to the wireless channel setting controller,
• wherein the wireless channel setting controller compares the transmission power value provided by a specific mobile station through the common channel with a predetermined threshold value and,
• when the transmission power value is lower than the predetermined threshold value, the wireless channel setting controller continues the transmission/reception of signals through the common channel with the specific mobile station, and
• when the transmission power value exceeds the predetermined threshold value, the wireless channel setting controller sets the individual channel for the specific mobile station and transmits an instruction to the control signal processor to continue the transmission/reception of signals through the individual channel.
