1. A method for constructing a power spectrum based connection admission control table including the steps of:

  • (a) using a predetermined scheduling policy and a predetermined quality of service for communications, determining a maximum equivalent aggregate average power Ψ

    max of an arrival rate of cells for all calls admitted to a node, which maintains said predetermined quality of service, as a function of at least an aggregate power spectrum DC component γ

    T but not as a function of a constant equivalent half-power bandwidth Be of said arrival rate of cells for all calls, for which Be individual component equivalent average powers Ψ

    e are determined for all calls,(b) storing the value of Ψ

    max determined in step (a) in a table entry that is indexed by at least the value of γ

    T used to determined said stored value of Ψ

    max, and(c) repeating steps (a)-(b) for multiple different values of γ

    T in a range of expected values for γ

    T.
