In today's highly competitive telecommunications industry, service providers provide customer's with a wide variety of voice, data, video, and internet services. Because of the complexity of service provider network systems and consumer premise equipment being deploying in the field to provide such services, service providers must utilize highly trained technicians to install and fix problems with the consumer premise equipment. However, such technicians inevitably encounter problems that require assistance.
Typically, service providers utilize call centers that have trained personnel to assist the technicians by answering calls from technicians and performing the analysis of the problem and providing the technician with a proposed solution. Due to the complexity of the systems involved, such call centers may receive a very large number of support calls from technicians in the field installing such products. Such calls can be costly in terms of time and resources needed to train the personnel answering the calls from technicians, and in terms of the time and resources utilized by employing such trained personnel.
Therefore, there is a need for an approach that provides a troubleshooting system that can allow the technician to interact with the system to troubleshoot and solve the problem.
Various exemplary embodiments are illustrated by way of example, and not by way of limitation, in the figures of the accompanying drawings in which like reference numerals refer to similar elements and in which:
A preferred apparatus, method, and software for providing interactive troubleshooting are described. In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the preferred embodiments of the invention. It is apparent, however, that the preferred embodiments may be practiced without these specific details or with an equivalent arrangement. In other instances, well-known structures and devices are shown in block diagram form in order to avoid unnecessarily obscuring the preferred embodiments of the invention.
Traditionally, technicians would contact the call center 105 to obtain help with troubleshooting problems from live agents or operators. That is, these personnel would answer calls from the technicians and perform analysis of the problem to provide the technician with a proposed solution. Because of the complexity of service provider network systems and consumer premise equipment (CPE) being deployed in the field, such call centers would typically receive a very large number of support calls from technicians in the field installing such products. These calls can be costly in terms of the required number of trained personnel for servicing the technicians.
In recognition of the above shortcomings, the interactive troubleshooting system 103 provides an automated service inquiry (e.g., problems relating to installation, service, etc.) resolution mechanism, whereby a robotic chat application is employed. This robotic chat application operates with a database of flow definitions for interacting with technicians in the field to solve their provisioning problems preferably without human interaction. This system can thus reduce the call volume from field technicians to the call center 105, and thus minimize the overhead costs for operating such a call center as well as increase the overall efficiency of the provisioning and troubleshooting processes.
According to one embodiment, the interactive troubleshooting system 103 can communicate with a network management system 115, a provisioning system 117, a service test system 119, and a network activation system 121. The interactive troubleshooting system 103 can have access to the various systems 115, 117, 119, and 121 in order to gather information during troubleshooting and to test and correct problems. For example, the interactive troubleshooting system 103 can access the network management system 115 and/or the provisioning system 117 to collect information regarding the customer network(s) and the services that the customer network currently has or has ordered (e.g., customer telephone or account number that can be used to retrieve customer information via network databases, etc.). Also, the interactive troubleshooting system 103 can access the service test system 119 to conduct tests on the system to aid in troubleshooting problems, and can access the network activation system 121 to help the technicians during, for instance, installation and initiation of services for the customers.
The troubleshooting engine 205 includes a question and answer module 211, a system monitoring module 213, a query execute module 215, and a command sending module 217. The troubleshooting engine 205 has access to the flow definition database 207 and the query database 209, as well as to the various components of the service provider network 101, such as the network management system 115, the provisioning system 117, the service test system 119, and the network activation system 121.
In one embodiment, the queries generated by the module 215 to the database 209 are in form of an XQuery, which is a structured query language (SQL). XQuery provides the capability to generate queries of eXtensible Mark-up Language (XML) data. Although the system query execute module 215 and query database 209 are described with respect to XQuery, it is contemplated that other query languages can be utilized.
Once the chat session is initiated, in step 303, the question and answer module 211 will pose questions to and receive answers from the technician regarding the problem encountered or the process the technician wants to perform. Alternatively, other methods for collecting data pertaining to the service inquiry can be utilized. The system monitoring module 213 can retrieve information regarding the particular customer network under consideration, and can check various network settings, connections, etc., by communicating with the network management system 115, the provisioning system 117, the service test system 119, and the network activation system 121. Thus, the question and answer module 211, in conjunction with the information received by the system monitoring module 213 and the answers provided by the technician via the chat interface 201, can pose any additional question needed or a series of questions in order to narrow down the type of problem being encountered. The question and answer module 211 can also provide the technician with various menus of options via which the technician can request help, for example, regarding testing or initiation of a customer's service.
Based on the answers provided by the technician to the questions posed by the question and answer module 211 and based on the information retrieved by the system monitoring module 213 during the chat session, the robotic chat application 203 will determine whether there are appropriate flow definitions available for the present situation, in step 305. The robotic chat application 203 will thus check the flow definition database 207 to determine if an appropriate flow definition is available. If it is determined that no such flow definition is available (e.g., if this is an uncommon problem for which a flow definition has not yet been defined), then a new flow definition and corresponding query (e.g., xquery) will need to be created and added to their respective databases, as in step 307. In order to create such new flow definitions and xqueries, it may be necessary to utilize the services of the call center 105 in order to research and resolve the service inquiry. If, however, it is determined that an appropriate flow definition is available, then the process proceeds to step 309.
In step 309, the appropriate flow definition is retrieved from the flow definition database 207, based on the answers that the technician provided to the questions posed in step 303, and possibly also based on information gathered by the system monitoring module 213. The flow definition may also include one or more questions that are posed to the technician in order to gather additional information from the technician as needed by the flow definition, in step 311. Once the technician has successfully navigated all the flow definitions in step 311, then the robotic chat application 203 retrieves an xquery, in step 313, from the xquery database 209.
The xquery retrieved in step 313 or created in step 307 can be executed by the xquery execute module 215 to obtain configuration commands in step 315. When the xquery is executed, then the command sending module 217 sends configuration commands to the provisioning system 117 (or other appropriate network component, such as, the network management system 115, the service test system 119, the network activation system 121, etc.), in step 317, in order to correct the problem, or initiate or test the service.
The interactive troubleshooting system 103 thereby provides an interactive robotic chatting session for the technicians, where all the technicians need to do is answer the questions posed. The system 103 provides a solution in a generic format that can be implemented by the various network components without the need for making computer code changes to implement such solutions. For example, the system uses xqueries to generate an XML that is sent to the network component (or service system), and the system can be provided with graphical user interfaces that allow administrative personnel to change the xquery format if necessary. Any change to the interface between the service and system is generic, which thereby eliminates very expensive code changes when the service needs to be changed. It is noted that other standard database languages instead of xquery can be used if desired.
The robotic chat application 203 asks a series of questions of the technician, generates a workflow to activate the xquery to reconfigure the system, and thus uses the xquery to control the flow and configuration to resolve a particular issue. When something needs to be added to the process, the process can simply be modified by adding a question to the flow definition and associating the new xquery with the new question and answer.
The whole flow process of the interactive troubleshooting system 103 advantageously utilizes a generic interface that can be used to be interactive with various client systems. For example, the chat interface 201 can communicate with chat clients of any type and running on any type of system (e.g., web client systems, text-to-speech interactive voice response (IVR) systems, mobile wireless client systems, etc.).
The interactive troubleshooting system can advantageously utilize existing provisioning systems to reduce or eliminate the need to modify such systems, and which ensures that problems are being solved in the proper manner.
Thus, the interactive troubleshooting system is totally configurable. The system can process flow definitions and function calls can be configured without any code change, thus eliminating the dependency on release schedules. The system is also plug-and-play. No restrictions are provided on interface format. Any function available in the systems can be plugged-in to define a step-by-step flow definition to provide interactive solution to complex problems. Also, the system is polymorphic. The system is compatible with a variety of clients (e.g., chat clients, voice portals, mobile devices, etc.). Once the process flow is defined, the system can be invoked from any type of client.

An XQuery processor 419 (e.g., similar to the questions and answer module 211 in
Process steps for the troubleshooting scenarios are defined in the form of a flow definition in the system. When the user launches the interactive troubleshooting for a scenario, a flow engine 421 creates an instance of the flow definition and moves through the steps as per the logic defined in the flow definition.

Process steps for the troubleshooting scenarios are defined in the form of a flow definition in the system. Flow logic that connects boxes W1-W11 represents the flow definition. Each step is identified as either a client or server interaction step depending on the interaction type. In the flow definition section in
An XQuery transformation is defined for each step to generate the necessary xml that needs to be sent. Boxes X11-X14 are the XQuery transformations that generate interactive questions for corresponding client steps. Boxes X21-X27 are the XQuery transformations for server steps to call the functions in the external systems.
All these XQuery transformations are stored in the database 435. When user launches interactive troubleshooting for a scenario at the buddy frontend 401, the flow engine 421 creates an instance of the flow definition and executes the transformation associated with each step and moves through the steps as per the logic defined in the flow.
X11 is the XQuery transformation for client step W1. When XQuery processor 419 executes X11 transformation associated with work step W1, the result is a set of questions that will be sent to the client program as shown in
In this manner, when the flow engine 421 runs from step W1 through step W11, it results in an interactive troubleshooting solution as shown in
The processes described herein may be implemented via software, hardware (e.g., general processor, Digital Signal Processing (DSP) chip, an Application Specific Integrated Circuit (ASIC), Field Programmable Gate Arrays (FPGAs), etc.), firmware or a combination thereof. Such exemplary hardware for performing the described functions is detailed below.
The computer system 600 may be coupled via the bus 601 to a display 611, such as a cathode ray tube (CRT), liquid crystal display, active matrix display, or plasma display, for displaying information to a computer user. An input device 613, such as a keyboard including alphanumeric and other keys, is coupled to the bus 601 for communicating information and command selections to the processor 603. Another type of user input device is a cursor control 615, such as a mouse, a trackball, or cursor direction keys, for communicating direction information and command selections to the processor 603 and for controlling cursor movement on the display 611.
According to an embodiment of the invention, the processes described herein are performed by the computer system 600, in response to the processor 603 executing an arrangement of instructions contained in main memory 605. Such instructions can be read into main memory 605 from another computer-readable medium, such as the storage device 609. Execution of the arrangement of instructions contained in main memory 605 causes the processor 603 to perform the process steps described herein. One or more processors in a multi-processing arrangement may also be employed to execute the instructions contained in main memory 605. In alternative embodiments, hard-wired circuitry may be used in place of or in combination with software instructions to implement the embodiment of the invention. Thus, embodiments of the invention are not limited to any specific combination of hardware circuitry and software.
The computer system 600 also includes a communication interface 617 coupled to bus 601. The communication interface 617 provides a two-way data communication coupling to a network link 619 connected to a local network 621. For example, the communication interface 617 may be a digital subscriber line (DSL) card or modem, an integrated services digital network (ISDN) card, a cable modem, a telephone modem, or any other communication interface to provide a data communication connection to a corresponding type of communication line. As another example, communication interface 617 may be a local area network (LAN) card (e.g. for Ethernet™ or an Asynchronous Transfer Model (ATM) network) to provide a data communication connection to a compatible LAN. Wireless links can also be implemented. In any such implementation, communication interface 617 sends and receives electrical, electromagnetic, or optical signals that carry digital data streams representing various types of information. Further, the communication interface 617 can include peripheral interface devices, such as a Universal Serial Bus (USB) interface, a PCMCIA (Personal Computer Memory Card International Association) interface, etc. Although a single communication interface 617 is depicted in
The network link 619 typically provides data communication through one or more networks to other data devices. For example, the network link 619 may provide a connection through local network 621 to a host computer 623, which has connectivity to a network 625 (e.g. a wide area network (WAN) or the global packet data communication network now commonly referred to as the “Internet”) or to data equipment operated by a service provider. The local network 621 and the network 625 both use electrical, electromagnetic, or optical signals to convey information and instructions. The signals through the various networks and the signals on the network link 619 and through the communication interface 617, which communicate digital data with the computer system 600, are exemplary forms of carrier waves bearing the information and instructions.
The computer system 600 can send messages and receive data, including program code, through the network(s), the network link 619, and the communication interface 617. In the Internet example, a server (not shown) might transmit requested code belonging to an application program for implementing an embodiment of the invention through the network 625, the local network 621 and the communication interface 617. The processor 603 may execute the transmitted code while being received and/or store the code in the storage device 609, or other non-volatile storage for later execution. In this manner, the computer system 600 may obtain application code in the form of a carrier wave.
The term “computer-readable medium” as used herein refers to any medium that participates in providing instructions to the processor 603 for execution. Such a medium may take many forms, including but not limited to non-volatile media, volatile media, and transmission media. Non-volatile media include, for example, optical or magnetic disks, such as the storage device 609. Volatile media include dynamic memory, such as main memory 605. Transmission media include coaxial cables, copper wire and fiber optics, including the wires that comprise the bus 601. Transmission media can also take the form of acoustic, optical, or electromagnetic waves, such as those generated during radio frequency (RF) and infrared (IR) data communications. Common forms of computer-readable media include, for example, a floppy disk, a flexible disk, hard disk, magnetic tape, any other magnetic medium, a CD-ROM, CDRW, DVD, any other optical medium, punch cards, paper tape, optical mark sheets, any other physical medium with patterns of holes or other optically recognizable indicia, a RAM, a PROM, and EPROM, a FLASH-EPROM, any other memory chip or cartridge, a carrier wave, or any other medium from which a computer can read.
Various forms of computer-readable media may be involved in providing instructions to a processor for execution. For example, the instructions for carrying out at least part of the embodiments of the invention may initially be borne on a magnetic disk of a remote computer. In such a scenario, the remote computer loads the instructions into main memory and sends the instructions over a telephone line using a modem. A modem of a local computer system receives the data on the telephone line and uses an infrared transmitter to convert the data to an infrared signal and transmit the infrared signal to a portable computing device, such as a personal digital assistant (PDA) or a laptop. An infrared detector on the portable computing device receives the information and instructions borne by the infrared signal and places the data on a bus. The bus conveys the data to main memory, from which a processor retrieves and executes the instructions. The instructions received by main memory can optionally be stored on storage device either before or after execution by processor.
While certain exemplary embodiments and implementations have been described herein, other embodiments and modifications will be apparent from this description. Accordingly, the invention is not limited to such embodiments, but rather to the broader scope of the presented claims and various obvious modifications and equivalent arrangements.
