Call distribution for a radio exchange station in a mobile communication system

A method of distributing calls in a radio exchanging station for use in a mobile communication system, said radio exchanging station comprising a selection processing execution processor and first through N-th call processing execution processors, where N represents a positive integer which is not less than two, said method comprising the steps of:

• periodically delivering, from an n-th call processing execution processor to said selection processing execution processor, an n-th use condition signal indicative of an n-th use condition of an n-th radio resource managed by said n-th call processing execution processor and an n-th load condition signal indicative of an n-th load condition of said n-th call processing execution processor, where n represents each of 1 through N;
• and
• determining, in said selection processing execution processor, on the basis of first through N-th use conditions and first through N-th load conditions, first through N-th call reception permissible numbers for distributing to said first through said N-th call processing execution processors, respectively.
