Abstract
Abstract A method, using a call processor, for selecting one of a plurality of call centers in a telephone network. The method begins by generating a routing plan comprising one or more rules that control how calls are to be distributed among the call centers. For each call to be distributed, the rules in the routing plan are executed for a set of valid call center destinations until a destination for the call has been selected or until all rules have been executed. If all rules have been executed and more than one call center is still a valid destination for the call, the remaining call center destinations are then further evaluated according to the rules to select a destination for the call.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
266 words
A method, using a call processor, for selecting which call center among a plurality of call centers in a telephone network is to receive an incoming telephone call, comprising the steps of: generating a routing plan comprising a set of rules, one or more rules in the set of rules having a conditions portion and an actions portion, the conditions portion of the rule defining one or more call routing conditions and the actions portion defining user selectable destination criteria for biasing an ability of at least one call center relative to the plurality of call centers to be selected to receive the incoming telephone call when the call routing conditions of the rule are met, the user selectable destination criteria including: (a) when call center answer statistics are available, timing preferences that apply a bias value to an estimated answer delay of the at least one call center of the plurality of call centers to thereby temporally bias the at least one call center relative to one or more call centers of the plurality of call centers; (b) when call center answer statistics are not available, target routing preferences that apply a bias value to an initial target routing percentage for at least one call center of the plurality of call centers to thereby load bias the target routing percentage of the at least one call center relative to one or more other call centers of the plurality of call centers; using the set of rules to determine which of the plurality of call centers in the telephone network is to receive the incoming call.
Claim 2
Independent Claim
266 words
A method, using a call processor, for selecting which call center among a plurality of call centers in a telephone network is to receive an incoming telephone call, comprising the steps of: generating a routing plan comprising a set of rules, one or more rules in the set of rules having a conditions portion and an actions portion, the conditions portion of the rule defining one or more call routing conditions and the actions portion defining user selectable destination criteria for biasing an ability of at least one call center relative to the plurality of call centers to be selected to receive the incoming telephone call when the call routing conditions of the rule are met, the user selectable destination criteria including: (a) when call center answer statistics are available, timing preferences that apply a bias value to an estimated answer delay of the at least one call center of the plurality of call centers to thereby temporally bias the at least one call center relative to one or more call centers of the plurality of call centers; (b) when call center answer statistics are not available, target routing preferences that apply a bias value to an initial target routing percentage for at least one call center of the plurality of call centers to thereby load bias the target routing percentage of the at least one call center relative to one or more other call centers of the plurality of call centers; using the set of rules to determine which of the plurality of call centers in the telephone network is to receive the incoming call.
Claim 3
Independent Claim
24 words
The method as described in 1 further includes the step of calculating an estimated answer delay for one or more of the call centers.
Claim 4
Independent Claim
24 words
The method as described in 1 further includes the step of calculating an estimated answer delay for one or more of the call centers.
Claim 5
Dependent Claim
52 words
The method as described in claim 2 wherein the step of using the set of rules includes the step of selecting the call center having the shortest estimated answer delay after the estimated answer delay for the at least one call center has been biased as directed by the routing plan rules.
Claim 6
Independent Claim
59 words
The method as described in 1 wherein the step of using the set of rules includes the step of selecting the call center having a smallest number of recently routed calls as compared to initial target percentages after the initial target percentages for the at least one call center have been biased as directed by the routing plan rules.
Claim 7
Independent Claim
59 words
The method as described in 1 wherein the step of using the set of rules includes the step of selecting the call center having a smallest number of recently routed calls as compared to initial target percentages after the initial target percentages for the at least one call center have been biased as directed by the routing plan rules.
Claim 8
Dependent Claim
36 words
The method as described as claim 1 wherein the user selectable destination criteria further include one or more constraints that eliminate call centers from the plurality of call centers that may receive the incoming telephone call.
Claim 9
Independent Claim
209 words
A method, using a call processor, for selecting which call center among a plurality of call centers in a telephone network is to receive an incoming telephone call, wherein the call centers provide call center answer statistics to the call processor, comprising the steps of: generating a routing plan comprising a set of rules, one or more rules in the set of rules having a conditions portion and an actions portion, the conditions portion of the rule defining one or more routing conditions and the actions portion of the rule defining user selectable criteria for biasing an ability of at least one call center relative to the plurality of call centers to be selected to receive the incoming telephone call when the call routing conditions of the rules are met, the user selectable criteria including timing preferences that apply to a bias value to an estimated answer delay of the at least one call center of the plurality of call centers to thereby temporally bias the at least one call center relative to one or more call centers of the plurality of call centers; and using the set of rules to route the incoming call to the call center having a smallest answer delay based on the temporal biasing.
Claim 10
Independent Claim
209 words
A method, using a call processor, for selecting which call center among a plurality of call centers in a telephone network is to receive an incoming telephone call, wherein the call centers provide call center answer statistics to the call processor, comprising the steps of: generating a routing plan comprising a set of rules, one or more rules in the set of rules having a conditions portion and an actions portion, the conditions portion of the rule defining one or more routing conditions and the actions portion of the rule defining user selectable criteria for biasing an ability of at least one call center relative to the plurality of call centers to be selected to receive the incoming telephone call when the call routing conditions of the rules are met, the user selectable criteria including timing preferences that apply to a bias value to an estimated answer delay of the at least one call center of the plurality of call centers to thereby temporally bias the at least one call center relative to one or more call centers of the plurality of call centers; and using the set of rules to route the incoming call to the call center having a smallest answer delay based on the temporal biasing.
Claim 11
Dependent Claim
35 words
The method as described in claim 6 wherein the selectable destination criteria further includes one or more constraints that eliminate call centers from the plurality of call centers that may receive the incoming telephone call.
