Patent ID: 8102993

Claim:
A method for routing a network call in a network call center which comprises multiple sub call centers, comprising: receiving a network call routing request from a requesting sub call center; reporting put-through call numbers and call losses by the multiple sub call centers periodically; determining a destination sub call center based on service capacity parameters of the multiple sub call centers corresponding to a network call service, wherein the service capacity parameters comprise put-through rates or call loss rates of the multiple sub call centers and forwarding the network call routing request to the determined destination sub call center for a call process; wherein the process of determining the destination sub call center based on the service capacity parameters of the multiple sub call centers corresponding to the network call service comprises: calculating the put-through rates or the call loss rates of the multiple sub call centers based on the put-through call numbers and the call losses reported by the multiple sub call centers, wherein a cyclic moving window algorithm is used for calculating the put-through rates or the call loss rates of the multiple sub call centers; taking a sub call center with the highest put-through rate or the lowest call loss rate as the destination sub call center.
