Patent ID: 8284921

Claim:
A method for sending a call batch that includes a plurality of calls, to one out of a possible “n” providers for near simultaneous transmission by the one provider to a plurality of recipients, wherein each of the “n” providers has an overall capacity, a current level of use, and an actual price charged for each particular call batch, the method comprising; preparing, within a central processing unit, a call batch having a certain size (PBU), the call batch being configured for near simultaneous transmission to a plurality of recipients; determining the overall capacity of each of the “n” providers (OC 1,n ); determining the current level of use by each of the “n” providers (CU 1,n ); for each of the “n” providers, subtracting the current level of use from the overall capacity to determine the actual capacity (AC 1,n ) of each provider; for each of the “n” providers, determining whether the actual capacity is less than the call batch size; eliminating from consideration those providers that have an actual capacity less than the call batch size; modifying the call batch size by a factor equal to the actual price charged by a particular provider (P 1,n ) divided by the highest price charged by any provider (P max ) to produce a price modified call batch size; for each remaining provider that has not been eliminated from consideration, computing, by using the central processing unit, a proportion price modified potential free capacity of each provider by subtracting the price modified call batch size from the actual capacity of each particular provider, and dividing the result by the overall capacity of each particular provider according to the relationship (OC 1,n −CU 1,n,−P 1,n ×PBU/P max )/OC 1,n ; and by using the central processing unit, allocating the call batch to the provider having the largest proportion price modified potential free capacity, and sending the call batch from the central processing unit to the allocated call batch provider; and transmitting the calls from the call batch provider to the plurality of recipients.
