Channel assignment method for multi-FA CDMA cellular systems

A channel assignment method for multi-FA (Frequency Assignment) CDMA cellular systems in which a base station communicates a plurality of mobile stations, comprising the steps of:

• comparing a first threshold value with cell loading when the base station receives a new call request;
• assigning a traffic channel in a first FA of the request, if the cell loading is less than the first threshold value, and searching a second FA of which cell loading is least, if not;
• comparing a second threshold value with cell loading in the second FA;
• and
• assigning a traffic channel in the second FA, if the cell loading is less than the second threshold value, and rejecting the request, if not.

A channel assignment method for multi-FA (Frequency Assignment) CDMA cellular systems in which a base station communicates a plurality of mobile stations, comprising the steps of:

• comparing a first threshold value with variance of received power when the base station receives a new call request;
• assigning a traffic channel in a first FA of the request, if the variance of received power is less than the first threshold value, and searching a second FA of which variance of received power is least, if not;
• comparing a second threshold value with the variance of received power;
• and
• assigning a traffic channel in the second FA if the variance of received power is less than the second threshold value, and rejecting the request, if not.

A channel assignment method for multi-FA (Frequency Assignment) CDMA cellular systems in which a base station communicates a plurality of mobile stations, comprising the steps of:

• comparing a first threshold value with standard deviation of received power when the base station receives a new call request;
• assigning a traffic channel in a first FA of the request, if the standard deviation of received power is less than the first threshold value, and searching a second FA of which standard deviation of received power is least, if not;
• comparing a second threshold value with standard deviation of received power;
• and
• assigning a traffic channel in a second FA if the standard deviation is less than the second threshold value, and rejecting the request, if not.
