1. A method for determining a least-interfered communications link between a private radio base station and a cellular mobile station, said private radio base station located within an area of said cellular mobile station, said private radio base station and said cellular mobile station sharing a multiplicity of frequencies for communication therein, said method comprising the steps of:

  • determining a first set of candidate frequencies for use by said private radio base station within said area of the cellular mobile station;

    ordering said first set of candidate frequencies into a second set of candidate frequencies pursuant to a first interference measurement;

    expanding said second set of candidate frequencies into a third set containing a multiplicity of frequency and timeslot pairings pursuant to a second interference measurement, each candidate frequency in said second set having a plurality of timeslots associated therewith;

    selecting a subset of said pairings from said third set, said candidate frequencies within said third set pairings having an associated signal interference value less than a given interference value being selected for said pairings subset, said pairings subset comprising said plurality of frequency hop lists in said step of dividing;

    reordering said frequency/timeslot pairings within said pairings subset;

    dividing said third set of said pairings into a plurality of frequency hop lists, each of said frequency hop lists containing a plurality of frequencies from said third set associated with a particular timeslot within said pairings, wherein said step of dividing said third set further comprises another averaging of the signal strengths of said frequency/timeslot pairings within said third set over a plurality of seconds; and

    selecting one of said frequency hop lists as the least-interfered communications link for said private radio base station.
