Abstract

Claims (241)

1. A system for balancing agent console load during automated call processing, comprising:

a console to operate a plurality of agent consoles;

a message server to balance a call session load on each agent console, comprising:

a load balance module to continually collect conditions from each agent console, to evaluate the conditions against each agent console, and to determine a load factor as a function of the conditions, wherein the load factor represents a normalized numeric metric 0≦LF i ′≦m determined in accordance with the formula:

a call distributor to assign the call sessions to the agent consoles commensurate to the corresponding load factor.

2. A system according to claim 1 , wherein the conditions comprise at least one of a state of a call previously assigned, a limit on a maximum number of call sessions, a priority of the call previously assigned, and a group to which an agent is assigned.

3. A system according to claim 1 , wherein the conditions comprise values for at least one of a difficulty resolving a caller's concerns and a difficulty experienced by an agent in dealing with the caller.

4. A system according to claim 1 , wherein t ij is set to a value for the current state comprising at least one of a waiting, attention, and active state.

5. A system according to claim 1 , wherein the call distributor performs an alternative call disposition when each agent console is unavailable to take the assigned call comprising at least one of handling one or more of the assigned call sessions through automated response, transferring one or more of the assigned call sessions to a live agent, and placing one or more of the assigned call sessions on hold.

6. A system according to claim 1 , wherein the load balance module assigns a maximum load factor to the agent console that receives one of the assigned call sessions and maintains the maximum load factor until the agent console is ready to accept new calls.

7. A method for balancing agent console load during automated call processing, comprising:

operating a plurality of agent consoles;

processing a plurality of call sessions; and

balancing a call session load on each agent console, comprising:

continually collecting conditions from each agent console;

evaluating the conditions against each agent console and determining a load factor as a function of the conditions to represent a normalized numeric metric 0≦LF i ′≦m in accordance with the formula:

assigning the call sessions to the agent consoles commensurate to the corresponding load factor.

8. A method according to claim 7 , wherein the conditions comprise at least one of a state of a call previously assigned, a limit on a maximum number of call sessions, a priority of the call previously assigned, and a group to which an agent is assigned.

9. A method according to claim 7 , wherein the conditions comprise values for at least one of a difficulty resolving a caller's concerns and a difficulty experienced by an agent in dealing with the caller.

10. A method according to claim 7 , wherein t ij is set to a value for the current state comprising at least one of a waiting, attention, and active state.

11. A method according to claim 7 , further comprising:

performing an alternative call disposition when each agent console is unavailable to take the assigned call sessions, comprising at least one of:

handling one or more of the assigned call sessions through automated response;

transferring one or more of the assigned call sessions to a live agent; and

placing one or more of the assigned call sessions on hold.

12. A method according to claim 7 , further comprising:

assigning a maximum load factor to the agent console that receives one of the assigned call sessions; and

maintaining the maximum load factor until the agent console is ready to accept new calls.

13. A system for balancing agent console load during automated call processing, comprising:

a console to operate a plurality of agent consoles;

a call processor to process a plurality of call sessions; and

a message server to balance a call session load on each agent console, comprising:

a load balance module to assign a fixed limit to the call sessions for each agent console, to continually collect conditions from each agent console, to evaluate the conditions against each agent console, and to determine a load factor as a function of the conditions, wherein the load factor represents a normalized numeric metric 0≦LF i ≦m determined in accordance with the formula:
