Abstract:
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; andassigning 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; andassigning the call to one of the multi-full rate channel combinations identified by the multi-full rate channel sort.
