1. A method for use in a cellular telephone system for assigning a multi-full rate channel combination of traffic channels to a request for a call, comprising the steps of:

  • performing a full rate channel sort to identify available full rate channels that meet a certain service type for the call below an operator allowed cost threshold related to radio conditions;

    performing a multi-full rate channel sort on the identified full rate channels found in the full rate channel sort to identify multi-full rate channel combinations that meet a certain service rate for the call; and

    assigning the call to one of the identified multi-full rate channel combinations by;

    determining whether at least one multi-full rate channel combination meets the requested service rate by;

    determining that no multi-full rate channel combinations as identified by the multi-full rate channel sort meet the requested service rate;

    determining that the requested service rate for the call has not reached the minimum acceptable service rate level;

    degrading the requested service rate of the call to a next available lower service rate level;

    performing the multi-full rate channel sort process again on the identified full rate channels found in the full rate channel sort to identify multi-full rate channel combinations that meet the degraded service rate; and

    assigning the call to one of the multi-full rate channel combinations identified by the multi-full rate channel sort.
