Abstract
A call service center can include a call routing system that can use one or more action object identifiers. In one embodiment, a future action object identifier is associated with a task that is desired or otherwise intended to be performed at the call service center. The call routing system may route the call to a module that is not associated with the future action object identifier or perform a portion of a task within the same module, wherein the portion of the task is not associated with the future action object identifier. In another embodiment, at least two action object identifiers can be passed with a call from one module to another module. In a particular embodiment, a past, current, or future action object identifier, other information related to the call, or any combination thereof may be passed from one module to another module with the call.
Description
BACKGROUND

1. Field of the Disclosure


The present disclosure relates to call routing systems, and more particularly to methods, data processing systems, and data processing system readable media for use in call routing systems.


2. Description of the Related Art


Many businesses use call service centers as a way to conduct business with their customers. Operating a call services center can be expensive, particularly if an attendant needs to interact with every or nearly every caller. Automating call service centers typically includes using a call routing system. Insufficient information may be provided to a call routing system. If insufficient information is provided, the call may be routed to an improper destination, or the call may need to be manually dispositioned by an attendant. The former can be problematic because it can increase the caller's frustration with the call service center and may result in potential lost revenue. The latter can be problematic because the purpose of automating is to reduce having calls, that could otherwise be properly routed, manually dispositioned by an attendant.

DETAILED DESCRIPTION

A call service center can include a call routing system that can use one or more action object identifiers. In one embodiment, an action object identifier can be associated with a task that is desired or otherwise intended to be performed at the call service center. The call routing system may route the call to a module that is not associated with the action object identifier or perform a portion of a task within the same module, wherein the portion of the task is not associated with the action object identifier. The use of the one or more action object identifiers can help a data processing system or a human attendant in more accurately handling the routing of the call. In another embodiment, at least two action object identifiers can be passed with a call from one module to another module. In a particular embodiment, a past action object identifier, a current action object identifier, a future action object identifier, other information related to the call, or any combination thereof may be passed from one module to another module along with the call. By using more than one action object identifier, more complex logic can be used by a data processing system or a human attendant can review the action object identifiers to more accurately route the call, as more variables are available to determine how to route of the call. A log file or other data from a database, storage network, or other memory does not need to be accessed, and thus, the call can be routed quicker and more accurately.


In a first aspect, a method of using a call routing system can include generating an action object identifier at a first module in response at least in part to a call, and routing the call to a second module that does not correspond to the action object identifier. The method can also include routing the call to a third module that is associated with the action object identifier after routing the call to the second module.


In a second aspect, a data processing system can include a first module configured to generate an action object identifier and pass or have passed a call to a second module that does not correspond to the action object identifier. The data processing system can also include a second module configured to perform a first task regarding the call, wherein the first task does not correspond to the action object identifier, and pass or have passed the call to a third module that is associated with the action object identifier. The data processing system can further include a third module configured to perform a second task regarding the call, wherein the second task is associated with the action object identifier.


In a third aspect, a data processing system readable medium can have data to be used with a call routing system, wherein the data is embodied within the data processing system readable medium. The data can include an instruction to generate an action object identifier at a first module in response at least in part to a call, an instruction to route the call to a second module that does not correspond to the action object identifier, and an instruction to route the call to a third module that is associated with the action object identifier after routing the call to the second module.


In a fourth aspect, a data processing system readable medium can have data to be used with a call routing system, wherein the data is embodied within the data processing system readable medium. The data can include an instruction to pass a call, a first action object identifier, and a second action object identifier from a first module to a second module, wherein the first and second modules are within the call routing system.


As used herein, the terms “comprises,” “comprising,” “includes,” “including,” “has,” “having” or any other variation thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, article, or apparatus that comprises a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Further, unless expressly stated to the contrary, “or” refers to an inclusive or and not to an exclusive or. For example, a condition A or B is satisfied by any one of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present).


Additionally, for clarity purposes and to give a general sense of the scope of the embodiments described herein, the use of “a” or “an” are employed to describe one or more articles to which “a” or “an” refers. Therefore, the description should be read to include at least one whenever “a” or “an” is used, and the singular also includes the plural unless it is clear that the contrary is meant otherwise.


Unless stated otherwise, any combination of parts of a system may be bi-directionally or uni-directionally coupled to each other, even though a figure may illustrate only a single-headed arrow or a double-headed arrow. Arrows within the drawing are illustrated, as a matter of convenience, to show a principal information, data, or signal flow within the system or between the system and one or more components outside the system, one or more modules outside the system, another system, or any combination thereof in accordance with an embodiment. Coupling should be construed to include a direct electrical connection in one embodiment and alternatively, may include any one or more of an intervening switch, resistor, capacitor, inductor, router, firewall, network fabric or the like between any combination of one or more components, one or more devices, or one or more modules.


Unless otherwise defined, technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. In addition, the methods and examples disclosed are illustrative only and not intended to be limiting.



FIG. 1 includes a general diagram of a caller 164 using a call service center 100. The call service center 100 can receive a call from a caller 164 that allows the caller to obtain information, products, or services, potentially without using an attendant. Thus, the call service center 100 can be used by a wide variety of businesses including manufactures, retailers, distributors, telephone service providers, airlines, etc. The call service center 100 can be designed as described herein to help automate routing of calls within the call service center 100 while still allowing an attendant or other human to interact with the caller to reduce caller frustration, reduce the likelihood that the caller, who may intend on purchasing a product or service, leaves without successfully making the purchase, etc. After reading this specification, skilled artisans will appreciate that the architectures and methods described herein can be adapted to the need or desires of the entity using a call service center.


The call service center 100 can include a data processing system 120 that is bi-directionally coupled to an antenna 110 and an attendant terminal 142. In another embodiment, the antenna 110 is not used, particularly if the phone 162 is a wireline phone, rather than a wireless phone as illustrated in FIG. 1. A human attendant 144 can be present at the attendant terminal 142. A caller 164 can use a phone 162 to call the call service center 100 and transact business with the entity operating the call service center 100. The call may include speech of the caller 164 that may be received by the call service center 100. The caller 164 may or may not speak at all during the call. In one embodiment, the phone 162 is communicatively coupled to the data processing system 120, via the antenna 110. The phone 162 can include a wireline phone or a wireless phone. The phone 162 can include a conventional telephone, a cell phone, a voice over Internet protocol phone, or the like. Wires, switches, routers, or potentially other equipment (not illustrated) may be used to communicatively couple the phone 162 to the data processing system 120.


The data processing system 120 can be part of or include a call routing system, as described herein. Each of the antenna 110 and attendant terminal 142 can be coupled to the data processing system 120 through one or more input/output (“I/O”) ports 1202. In another embodiment, separate input ports and output ports could be used. For simplicity, I/O ports 1202 will be used to refer to any or all of input ports, output ports or input/output ports. The data processing system 120 further comprises a controller 1220 that is bi-directionally coupled to modules that are designed to perform actions as requested by a caller using the call service center 100. In the embodiment as illustrated in FIG. 1, the controller 1220 is bi-directionally coupled to module 1231, module 1232, module 1233, and module 1234. Although not illustrated, one or more other modules may be present. Each of the modules 1231 through 1234 can perform one or more actions at the call service center 100. Such actions can include authenticating caller 164, determining account status or other account information of the caller 164, providing information regarding products or services of the entity operation the call service center 100, allowing the caller 164 to purchase products or services at the call service center 100, perform other suitable action, or any combination thereof. Each of the modules 1231 through 1234 may or may not be configured to route the call to the other of the modules 1231 through 1234. In another embodiment, more or fewer modules may be used.


The controller 1220 is also bi-directionally coupled to an attendant interaction module 1240, a disposition module 1260, and a routing module 1280. The attendant interaction module 1240 can allow an attendant input signal from the attendant terminal 142 to be received at the data processing system 120 when the attendant 144 is servicing a call. The attendant interaction module 1240 is bi-directionally coupled to the disposition module 1260 and the routing module 1280. The disposition module 1260 can receive an attendant interaction signal from the attendant interaction module 1240 or a signal from the controller 1220 in order to generate a disposition signal at the disposition module 1260 in order to disposition a call. The disposition module is bi-directionally coupled to the routing module 1280. The routing module 1280 may receive signals from the controller 1220, the attendant interaction module 1240, the disposition module 1260, any one or more of the modules 1231 through 1234, or any combination thereof in order to route the call to an appropriate module when servicing the call.


Although not illustrated, other connections and memories may reside in or be coupled to the data processing system 120. Such memories can include a hard disk, content addressable memory, static random access memory, cache, first-in-first-out (“FIFO”), a database, a storage network, other memories, or any combination thereof. The memories can include media that can be read by the data processing system 120. Therefore, each of the types of memory includes a data processing system readable medium.


Portions of the methods described herein may be implemented in suitable software code or other data for carrying out the methods described. In one embodiment, computer-executable instructions may be lines of assembly code or compiled C++, Java, or other language code. In another embodiment, the code may be contained on a data storage device, such as a hard disk, magnetic tape, floppy diskette, optical storage device, networked storage device(s), or other appropriate data processing system readable medium or storage device.


Functions preformed by any one or more of the modules may be combined with one or more other modules or the controller 1220. For example, the disposition module 1260 and the routing module 1280 may be combined into a single module. In still another embodiment, one or more of the modules may be located outside of the data processing system 120. For example, the attendant interaction module 1240 could reside in the attendant terminal 142. Further, more than one type of module may reside in one or more devices. For example, a disposition module may reside within the phone 162, the attendant terminal 142, or both in addition to or in place of the disposition module 1280 within the data processing system 120. Such disposition modules may be substantially the same or different when compared to each other. Also, any single module may be embedded within a plurality of integrated circuits, chip sets, circuit boards, or the like. Additionally, a software program or its software components with such code may be embodied in more than one data processing system readable medium in more than one computer or other item having a controller or a processor.


Attention is now directed toward a method of using a call routing system for the call service center 100 in accordance with an embodiment, as illustrated in FIG. 2. The method can include receiving a call from the caller 164, at block 222. The method can also include generating an action object identifier at a first module in response at least in part to the call, at block 242. The method can further include routing the call to a second module that does not correspond to the action object identifier, at block 262. The method can still further include the call to a third module that is associated with the action object identifier after routing the call to the second module, at block 282. Some details regarding the operations performed as described in blocks 242, 262, and 282 are described with respect to exemplary, non-limiting embodiments, as illustrated in FIGS. 3 and 4. Occasional references will be made to the call service center 100 or one or more portions thereof, as illustrated in FIG. 1, when describing methods as illustrated in FIGS. 3 and 4.



FIGS. 3 and 4 include process flow diagrams that illustrate potential actions that may occur within an authentication module and an account status module. Referring to FIG. 3, signals can be received from an incoming call coming from the caller 164 at phone 162, at item 302. In one embodiment, the call includes a communication in which a caller's voice can be transmitted from the phone 162 to the data processing system 120. The caller 164 may or may not speak during the call. The call from the phone 162 can be received at I/O port 1202 of the data processing system 120 via the antenna 110. The signal can be transmitted from the I/O port 1202 to the controller 1220. The controller 1220 may transmit the signals to an authentication module that may be module 1231 in FIG. 1. The authentication module can be used authenticate the caller 164. The transmission from the controller 1220 may be directly from the controller 1220 to the module 1231 or may occur via the routing module 1280.


The method can include authenticating the caller, at block 322 in FIG. 3. In one embodiment, one or more conventional techniques may be used for authenticating the caller. Referring to FIG. 1, module 1231 may be used to perform the task of authentication. After authentication, the data processing system 120 may transmit one or more options to the caller 164 at phone 162 regarding one or more other actions from which the caller 164 can select. The actions can include obtaining information, such as account information, order status information, product or service information, ordering a product or service, paying a bill, transferring funds, other suitable information or transaction, or any combination thereof.


The method can also include receiving a user input signal associated with purchasing a service, at block 342. In another embodiment, the user input signal could be associated with purchasing a product or any combination of one or more products or one or more services. Referring to FIG. 1, the caller 164 at phone 162 can activate one or more keys, buttons, or other controls, or any combination thereof of the phone 162 to generate the user input signal that is received by the data processing system 120. In this particular embodiment, the caller 164 has selected to purchase a service.


Module 1231 may generate one or more action object identifiers associated with the call. In one embodiment, past, current, and future action object identifiers are generated. An action object identifier can be associated with a task that has been, is being, or is desired or otherwise intended to be performed. In a particular embodiment, a past action object identifier can be associated with a task that has been performed, a current action object identifier can be associated with a task that is being performed, and a future action object identifier can be associated with a task that is desired or otherwise intended to be performed. The past, current, and future action object identifiers may be identified with respect to a particular module. For example, the same action object identifier may have been a past action object identifier at the particular module and may be a current action object identifier at another module that immediately preceded the particular module. The level of detail regarding the action object identifiers can be varied. For example, each of the past, current, and future action object identifiers may include a reference to a module (e.g., module 1231 to 1234) or to a more particular aspect or a portion of a task that was, is, or is desired or otherwise intended to be performed at the module.


In FIG. 3, exemplary action object identifiers include “Past AO: Receive_Call,” “Current AO: Authenticate_Caller,” “Future AO: Buy_Service,” at block 344. The information within block 344 indicates that, at module 1231, an incoming call was received before reaching module 1231, authentication is the task performed by module 1231, and the caller 164 desires to purchase a service. Other information (not illustrated) may be generated, such as whether the current action object was successfully completed, a reason why the current action object was or was not successful, other suitable information regarding the processing of the call, or any combination thereof. The method can include saving the past action object identifier, current action object identifier, future action object identifier, and potentially other information. Such information may be stored within memory (not illustrated) within the data processing system 120, or a database or other storage (not illustrated) coupled to the data processing system 120.


The method can further include determining whether the caller 164 intends to purchase a product, a service, or any combination thereof, at decision act 362. The data processing system 120 can analyze the future action object identifier to determine that the caller 164 desires to purchase a service (“yes” branch from decision act 362). The call and any one or more of the past action object identifier, current action object identifier, future action object identifier, other information, or any combination thereof may be passed to an account status module. In one embodiment, the account status module is module 1322 in FIG. 1. In a particular embodiment, the module 1321 may route the call and associated information to module 1322 or may have the routing module 1280 route the call and associated information to module 1322. Thus, the module 1321 can pass or can have passed the call and the associated information. If the caller 164 at phone 162 does not desire to purchase any products or services (“no” branch from decision act 362), the caller 164 at phone 162 may be routed to another module or allow other action to be taken by the data processing system 120 with or without further input from the phone 162. The determination whether the caller 164 intends to purchase a product, a service, or any combination thereof, at decision act 362, may be performed by the module 1321 or the routing module 1280.


The process at the account status module is illustrated in the process flow diagram in FIG. 4. The call and associated information can be passed to the account status module. In one embodiment, the account status module can be used by the entity that controls and operates the caller service center 100 to reduce the likelihood that the its customers will be allowed to make any purchases if they already are overdue in paying an outstanding balance, are at or have exceeded a credit limit of the caller's account, other one or more indicia that collecting money from the caller for an additional purchase would be difficult, or any combination thereof.


The call and associated information can be passed to the account status module from the authentication module, at item 402 in FIG. 4. The method can include retrieving account information of the caller's account, at block 422. The information may be obtained from memory (not illustrated) within the data processing system 100, or from a database, a storage network, or other external storage network (not illustrated). The method can further determine if the balance of the caller's account is less than zero, at decision act 424.


If the balance is not less than zero (“no” branch from decision act 424), the account status module can generate the past action object identifier, current action object identifier, future action object identifier, other information, or any combination thereof, at block 442. In one embodiment, one or more of the action object identifiers can be changed or otherwise generated by the account status module.


In a particular embodiment, the current action object identifier from the authentication module becomes the past action object identifier within the account status module. Thus, the past action object identifier can include “Past AO: Authenticate_Caller.” The current action object identifier can be associated with the account status module, which is where the call is currently being processed. The current action object identifier can include “Current AO: Check_Account.” Although not illustrated, a result identifier, a reason identifier, or both can be used to indicate that the action was successfully performed and that the account has a zero or positive balance. Note that a positive balance indicator may be used even if the balance is zero. Such information may be passed with the call. Referring to FIG. 4, the positive balance indicates that the determination in decision act 424 has been performed and the call is along the “no” branch from decision act 424.


An optional determination can be made regarding the future action object identifier from the authentication module. If the current module is not associated with the future action object identifier, the future action object identifier from the authentication module may also be the future action object identifier for the account status module. If the current module is associated with the future action object identifier but the call has not yet reached a particular portion of a task associated with the future action object identifier, the future action object identifier from the authentication module may also be the future action object identifier at this point in the process. In one particular embodiment, the caller desires to purchase a service, and therefore, the future action object identifier can be “Future AO: Buy_Service.”


Other information (not illustrated) may be generated, such as whether the current action object was successfully completed, a reason why the current action object was or was not successful, other suitable information regarding the processing of the call, or any combination thereof. The method can include saving the past action object identifier, current action object identifier, future action object identifier, and potentially other information. Such information may be stored within memory (not illustrated) within the data processing system 120, a database, or other storage (not illustrated) coupled to the data processing system 120.


The method can further include routing the call to the “Buy_Service” module, at block 444 in FIG. 4. The call and any one or more of the past action object identifier, current action object identifier, future action object identifier, other information, or any combination thereof may be passed to the “Buy_Service” module. In one embodiment, the “Buy_Service” module is module 1323 in FIG. 1. In a particular embodiment, the module 1322 may route the call and associated information to module 1323 or may have the routing module 1280 route the call and associated information to module 1323. Thus, the module 1322 can pass or can have passed the call and the associated information. The caller 164 at the phone 162 may be able to acquire or otherwise purchase one or more services that the caller 164 desires. At the “Buy_Service” module, the current action object identifier at the account status module becomes the past action object identifier at the “Buy_Service” module.


The future action object identifier at the account status module becomes the current action object identifier at the “Buy_Service” module, or the current action object identifier at the “Buy_Service” module may be different and potentially more specific to the portion of the task being performed at the “Buy Service” module. The future action object identifier can be assigned a zero or null value or may be assigned a different value after a further dialog with the caller 164 at the phone 162. For the example, the caller may desire to acquire a digital subscriber line (“DSL”) service for Internet access, and the future action object identifier can be “Future AO: Buy_DSL.”


The call can continue with the caller 164 at phone 162, the data processing system 120, or a combination thereof providing sufficient information to the caller 164 for him or her to decide whether to acquire the DSL service, provide sufficient information to the service provider to provide the service and properly bill the caller 164 for the service, perform other associated actions, or any combination thereof.


In one embodiment, the future action object identifier can be used to keep track of where the caller 164 at phone 162, the data processing system 120, or any combination thereof desires or otherwise intends to do, even though the call may need to be processed by one or more unassociated, intervening modules, or one or more unassociated, intervening portions of one or more tasks within the same module. By using the future action object identifiers, calls can be more accurately routed while still allowing optional or intervening processing of the call to occur.


Returning to decision act 424 in FIG. 4, a determination may be made that the balance of the caller's account is less than zero (“yes” branch). In one embodiment, the method can include announcing the amount due, and optionally, the due date, at block 462. In a particular embodiment, audio signals can be generated at the data processing system 120 and be transmitted to the phone 162. The phone 162 can receive the audio signals and convert them to audible signals that the caller 164 can hear. The audible signals can also prompt the caller 164 to decide whether he or she wants to make a payment. The caller 164 can activate one or more keys, buttons, or other controls, or any combination thereof of the phone 162 to generate a user input signal that is received by the data processing system 120.


After receiving the user input signal, the method can include determining whether a payment is to be made (decision act 464 in FIG. 4). In one embodiment, the user input signal may be associated with the “yes” branch from decision act 464. The method can further include receiving payment information, at block 482. The method can vary depending on how the payment will be made. A credit, bank, or smart card may be used, a bank checking or savings account may be used, money may be wire transferred, another suitable payment selection may be used, or any combination thereof. The caller 164 at phone 162 may need to take the balance to zero, become positive, reduce the current balance by a predetermining amount (e.g., $50, $100, etc.) or a predetermined fraction (e.g., reduce negative balance by 50%, 80%, etc.). The account status module can generate the past action object identifier, current action object identifier, future action object identifier, other information, or any combination thereof, at block 484. In one embodiment, one or more of the action object identifiers can be changed or otherwise generated by the account status module.


In a particular embodiment, the past action object identifier can include “Past AO: Authenticate.” The “Current AO: Check_Account.” If a payment was made to reduce the balance to zero or become positive, an optional result identifier, reason identifier, or both can indicated that the account status check was successfully performed and that the account has a zero or positive account balance. An optional determination can be made regarding the future action object identifier from the authentication module. If the current module is not associated with the future action object identifier, the future action object identifier from the authentication module may also be the future action object identifier for the account status module. If the current module is associated with the future action object identifier but the call has not yet reached a particular portion of a task associated with the future action object identifier, the future action object identifier from the authentication module may also be the future action object identifier at this point in the process. In one particular embodiment, the caller desires to purchase a service, and therefore, the future action object identifier can be “Future AO: Buy_Service.”


Other information (not illustrated) may be generated, such as whether the current action object was successfully completed, a reason why the current action object was or was not successful, other suitable information regarding the processing of the call, or any combination thereof. The method can include saving the past action object identifier, current action object identifier, future action object identifier, and potentially other information. Such information may be stored within memory (not illustrated) within the data processing system 120, a database or other storage (not illustrated) coupled to the data processing system 120.


The method can further include routing the call to the “Buy_Service” module, at block 486 in FIG. 4. The call and any one or more of the past action object identifier, current action object identifier, future action object identifier, other information, or any combination thereof may be passed to the “Buy_Service” module. The call can be further processed as described herein.


Returning to decision act 464, if the user input signals from phone 162 are associated with not making a payment or not making a sufficient payment, the caller 164 at phone 162 may be having a problem with the call service center 100. The account status module can generate the past action object identifier, current action object identifier, future action object identifier, other information, or any combination thereof, at block 492. In one embodiment, one or more of the action object identifiers can be changed or otherwise generated by the account status module.


In a particular embodiment, the past action object identifier can include “Past AO: Authenticate.” The current action object identifier may include “Current AO: Check_Account” in one particular embodiment. An optional result identifier, reason identifier, or both can indicate that the account status check was or was not successfully performed and that the account has a negative account balance. An optional determination can be made regarding the future action object identifier from the authentication module. If the current module is not associated with the future action object identifier, the future action object identifier from the authentication module may also be the future action object identifier for the account status module. If the current module is associated with the future action object identifier but the call has not yet reached a particular portion of a task associated with the future action object identifier, the future action object identifier from the authentication module may also be the future action object identifier at this point in the process. In one particular embodiment, the future action object identifier can be “Future AO: Buy_Service.”


Other information (not illustrated) may be generated, such as whether the current action object was successfully completed, a reason why the current action object was or was not successful, other suitable information regarding the processing of the call, or any combination thereof. The method can include saving the past action object identifier, current action object identifier, future action object identifier, and potentially other information. Such information may be stored within memory (not illustrated) within the data processing system 120, a database or other storage (not illustrated) coupled to the data processing system 120.


The method can further include routing the call to the attendant interaction module 1240, at block 494 in FIG. 4. The call and any one or more of the past action object identifier, current action object identifier, future action object identifier, future action object identifier, other information, or any combination thereof may be passed to the attendant interaction module 1240. In a particular embodiment, the module 1322 may route the call and associated information to the attendant interaction module 1240 or may have the routing module 1280 route the call and associated information to the attendant interaction module 1240. Thus, the module 1322 can pass or can have passed the call and the associated information.


In still another embodiment, the method may be interrupted at potentially nearly any time because the caller 164 made a wrong selection, the attendant 144 may determine that the caller 164 appears to be lost, the controller 1220 may determine that the call has been in a module too long or is causing an infinite loop to be performed by a module, or for another reason. Therefore, an interrupt signal may be generated by the phone 162, the attendant terminal 142, or the data processing system 120. The interrupt signal can be used to at least temporarily stop processing in order for another action to be taken.


For example, the caller 164 may determine that he or she desires to have an attendant 144 service the call. The phone 162 can generate an interrupt signal that is received by the controller 1220 of the data processing system 120. The controller 1220 can then transmit one or more signals to any one or more modules within the data processing system 120. For example, the controller 1220 can instruct the routing module to route the call, and optionally one or more action object identifiers, a result identifier for a current or other action object, and a reason identifier for the current or other action object to the attendant interaction module 1240. The attendant interaction module 1240 can transmit a notice to the attendant terminal 142 for the attendant 144 to service the call. The attendant terminal 142 can then transmit one or more attendant input signals to the attendant interaction module 1240 that can generate an attendant interaction signal. The attendant interaction signal can be transmitted to the disposition module 1260, which in turn, can generate a disposition signal that can be transmitted to the routing module 1280.


During the process, the call and associated information can be passed from one module to another module. When the past, current, and future action object identifiers, and other associated information are passed with the call, the modules within the data processing system 120, or the attendant 144 at the attendant terminal 142 may quickly analyze status information regarding the call without having to access a log file or otherwise retrieve data from storage. By not having to analyze data within a log file or retrieving information from storage, handling of the call at the call service center 100 may be done more quickly and efficiently.


Whenever a past object identifier, a current object identifier, a future object identifier, any other associated information, or any combination thereof is generated or used to route a call, such information can be stored within a log file. The log file can be used by the attendant, analyzing call data to improve or otherwise change a configuration of the call service center, or for another reason.


In an alternative embodiment, the balance determination 424 may be replaced by or performed in conjunction with a credit limit determination. For example, the determination could include determining whether the caller's account has a zero or negative credit limit (e.g., user was previously allowed to exceed his or her credit limit). If caller's account has a positive credit limit (“no” branch from decision act 424), the method can proceed as described with respect to block 442 and block 444. If the caller's account has a zero or negative credit limit (“yes” branch from decision act 424), the method can proceed as described with respect to decision act 464 and subsequent blocks.


In still another embodiment, the credit limit of the caller's account may be determined after retrieving account information of the caller 164 at block 442. An available amount remaining regarding the credit limit may be determined and the caller 164 may be able to purchase one or more products, one or more services, or any combination thereof to the extent the credit limit is not exceeded. If the caller 164 exceeds the available amount, the data processing system 120 can allow the caller 164 to delete one or more products, one or more services, or a combination thereof until the credit limit for the caller's account is no longer exceeded, require the caller 164 to pay the difference between the value of the purchased items and the available amount, allow the caller 164 to pay for the current items being purchased, or any combination thereof.


The use of one or more action object identifiers, other information, or any combination thereof by a call routing system can allow for more accurate routing of a call within a call service center. The likelihood of inaccurate routing or unnecessary human intervention by an attendant can be significantly reduced. Retrieving a log file or information from a database is not needed in order to use the call routing system as described. Therefore, more accurate automated routing with less human intervention can be achieved with a call routing system.


The call routing system may be used in a variety of call service centers. In one non-limiting embodiment, the call service center 100 can include a speech-enabled, self-service call routing system or call service center for performing one or more transactions or obtaining information from the entity that controls the call service center 100. The methods described herein are highly flexible and can be tailored to the particular needs to desires of the entity.


Note that not all of the activities described above in the general description or the examples are required, that a portion of a specific activity may not be required, and that one or more further activities may be performed in addition to those described. Still further, the order in which activities are listed are not necessarily the order in which they are performed.


Any one or more benefits, one or more other advantages, one or more solutions to one or more problems, or any combination thereof have been described above with regard to one or more particular embodiments. However, the benefit(s), advantage(s), solution(s) to problem(s), or any element(s) that may cause any benefit, advantage, or solution to occur or become more pronounced is not to be construed as a critical, required, or essential feature or element of any or all of the claims.


The above-disclosed subject matter is to be considered illustrative, and not restrictive, and the appended claims are intended to cover all such modifications, enhancements, and other embodiments, which fall within the scope of the present invention. Thus, to the maximum extent allowed by law, the scope of the present invention is to be determined by the broadest permissible interpretation of the following claims and their equivalents, and shall not be restricted or limited by the foregoing detailed description.
