## Background
BACKGROUND
1. Field of the Invention
Embodiments of the present invention provide a system and a method for managing a contact center. More particularly, embodiments of the present invention provide a system and a method for enabling a contact center to dynamically modify its routing configuration in response to variations in contacts and resources.
2. Description of Related Art
Contact centers are employed by many enterprises to service inbound and outbound communication with contacts/customers. A typical contact center includes a number of switches and routers for receiving and routing incoming packet-switched and/or circuit-switched contacts, and one or more resources, such as human agents and automated resources (e.g., Interactive Voice Response (IVR) units), to service the incoming contacts.
Contact centers distribute contacts, whether inbound or outbound, for servicing to any suitable resource according to predefined criteria. In many existing systems, the criteria for servicing a contact from the moment the contact center becomes aware of the contact until the contact is connected to an agent are client or operator-specifiable (i.e., programmable by the operator of the contact center), via a capability called vectoring. Normally, in present-day automatic call distribution (ACD), when an ACD system's controller detects an agent has become available to handle a contact, the controller identifies all predefined contact-handling queues for the agent (usually in some order of priority) and delivers to the agent the highest-priority, oldest contact that matches the agent's highest-priority queue. Generally, the only condition that results in a contact not being delivered to an available agent is where there are no contacts waiting to be handled.
The switches and routers that are employed in traditional contact center infrastructure and, more generally, in traditional computer/telecommunications infrastructure, are typically very large, very expensive, and are difficult to reconfigure once a particular network configuration has been established. Thus, while the use of such infrastructure may facilitate a reliable system, it also presents a number of drawbacks. For example, route configurations within the system do not change when resources (e.g., agents, automated media, etc.) are added or removed, resulting in inefficient network utilization. Furthermore, route configurations within the system do not change when networks become congested, because networks have no flexibility to adapt or reconfigure in response to changing traffic patterns. Still further, since switches are responsible for data forwarding and network control, their failure may have a detrimental effect on many other network components.
SUMMARY
In view of the foregoing, it would be advantageous to provide a system and method for enabling a contact center to dynamically modify its routing configuration in response to variations in contact requirements, contact center resources, and traffic patterns in order to optimize routing efficiency and reduce operating costs.
Embodiments in accordance with the present invention provide a self-configuring dynamic contact center. The contact center includes a plurality of resources, each resource associated with a set of attributes. The contact center further includes a plurality of dynamic switches connected to the resources, a dynamic controller connected to the dynamic switches and configured to control the operation of the dynamic switches, and a routing engine connected to the dynamic controller. The routing engine is configured to utilize the dynamic controller and the dynamic switches to determine the states of network paths between the dynamic switches, and is further configured to determine which of the resources are suitable to handle a contact based on requirements of the contact and the attributes of the resources. The routing engine may further be configured to determine which of the suitable resources is an optimal resource based on the requirements of the contact and the states of the network paths, and to utilize the dynamic controller and the dynamic switches to route the contact to the optimal resource, or, the routing engine may be configured to determine which of a plurality of routes between the contact and a suitable resource is an optimal route based on the requirements of the contact and the states of the network paths, and to utilize the dynamic controller and the dynamic switches to route the contact to the suitable resource via the optimal route.
Embodiments in accordance with the present invention further provide a computer-implemented method for establishing a self-configuring dynamic contact center. The computer-implemented method includes receiving a contact at a dynamic switch network comprising a plurality of dynamic switches interconnected by network paths, identifying a plurality of resources within the contact center that are suitable for handling the contact, determining the states of the network paths, designating one of the suitable resources as an optimal resource based on the states of the network paths, and routing the contact to the optimal resource.

FIG. 1 shows an illustrative embodiment of a self-configuring dynamic contact center 100 (hereinafter “the contact center 100”) in accordance with the present invention. The contact center 100 may include a session manager 110, a set of data stores or databases 114 containing contact or customer related information and other information that can enhance the value and efficiency of contact processing, and a plurality of servers, namely a media server 118, an interactive response unit (e.g., IVR) 122, a routing engine 126, and switches 1301-N, all interconnected by a local area network LAN (or wide area network WAN) 142 or other network connection technologies. A plurality of working agents operating packet-switched 1st agent communication devices 1341-N (such as computer work stations or personal computers), and/or circuit-switched 2nd agent communication devices 1381-N may be connected to respective switches 1301-N. The session manager 110 is further connected to a circuit switched network 154 (e.g., a Public Switch Telephone Network or PSTN) and a packet switched network 162 (e.g., a distributed processing network, such as the Internet). The packet-switched network 162 is in communication with one or more external 1st contact communication devices 169, and the circuit-switched network 154 with one or more external 2nd contact communication devices 180, used by customers to communicate with the contact center 100. A session border controller 158 is positioned between the session manager 110 and the networks 154 and 162 for processing communications passing between the session manager 110 and the networks 154 and 162 as further described below.
Although the preferred embodiment is discussed with reference to client-server architecture, it is to be understood that the principles of the present invention apply to other network architectures. For example, the present invention applies to peer-to-peer networks, such as those envisioned by the Session Initiation Protocol. In the client-server model or paradigm, network services and the programs used by end users to access the services are described. The client side provides a user with an interface for requesting services from the network, and the server side is responsible for accepting user requests for services and providing the services transparent to the user. By contrast in the peer-to-peer model or paradigm, each networked host runs both the client and server parts of an application program.
Additionally, the present invention does not require the presence of packet-or circuit-switched networks. The term “switch” or “server” as used herein should be understood to include a PBX, an ACD, an enterprise switch, an enterprise server, or other type of telecommunications system switch or server, as well as other types of processor-based communication control devices such as media servers, computers, adjuncts, etc.
In one embodiment, the session border controller 158 of the contact center 100 may be Avaya Inc.'s, G700 Media Gateway.TM, which may be implemented as a hardware component, such as via an adjunct processor or as a chip onboard the server. The session border controller 158 is responsible for providing the contact center 100 with a security gateway for protecting the contact center 100 from malicious attacks, toll fraud, malformed packets, and the like. It will be appreciated by those of ordinary skill in the art that the session border controller 158 may perform a variety of other functions, such as facilitating network connectivity, monitoring quality of service, and providing regulatory support.
The session manager 110 is responsible for routing and managing contacts inside of the contact center 100 (i.e., after the contacts have been admitted to the contact center 100 by the session border controller 158). Particularly, the session manager 110 communicates with the other SIP enabled devices (e.g., the media server 118, IVR 122, routing engine 126, and switches 1301-N) in the contact center 100 and is configured with routing and dial plans to facilitate appropriate forwarding of incoming contacts as designated by the routing engine 126 as further described below.
The routing engine 126 is responsible for determining where, within the contact center 100, incoming contacts should be routed to and notifying the session manager 110 accordingly. For example, the routing engine 126 may receive a notification from the session manager 110 indicating that an incoming contact has been received. The routing engine 126 may then scan an internal database for available resources (e.g., agents, the media server 118, etc.) within the contact center 100 which are best suited to handle that particular contact. The routing engine 126 may access customer/contact information stored in the database(s) 114 in order to make such a determination. The routing engine 126 may then transmit a response back to the session manager 110 indicating the specific resource to which the contact should be routed. For example, the routing engine 126 may indicate to the session manager 110 that, based on the language requirements of a particular contact, that contact should be routed to an appropriate agent at a particular one of the 1st agent communication devices 1341-N via a respective one of the switches 1301-N.
The IVR 122 provides an interactive, automated menu system for allowing incoming contacts to at least partially navigate to an appropriate resource within the contact center 100. For example, an incoming contact may be connected to the IVR 122, may select options to navigate through an automated menu, and may thereby be connected to an appropriate/desired resource without tying up contact center personnel. The IVR 122 may also perform other functions that will be familiar to those of ordinary skill in the art, such as allowing a contact to select a preferred language of communication, based on which the IVR system may intelligently route the contact to an agent who is fluent in the selected language.
The media server 118 of the contact center 100 is responsible for playing treatment messages for contacts when appropriate. Such treatment messages may include prerecorded announcements (e.g., “an agent will be with you shortly”), on-hold music, etc. The particular format of the treatment message may depend on the type of contact received. For example, video chat contacts may receive video messages, while phone call contacts may receive voice messages.
The first agent communication devices 1341-N are packet-switched devices that may include, for example, IP hardphones such as the Avaya Inc.'s, 4600 Series IP Phones.TM., IP softphones such as Avaya Inc.'s, IP Softphone.TM, Personal Digital Assistants or PDAs, Personal Computers or PCs, laptops, packet-based H.320 video phones and conferencing units, packet-based voice messaging and response units, packet-based traditional computer telephony adjuncts, peer-to-peer based communication devices, and any other communication device.
The second agent communication devices 1381-N are circuit-switched devices. Each of the second agent communication devices 1381-N corresponds to one of a set of internal extensions Ext1-N, respectively. The second agent communication devices 1381-N can include, for example, wired and wireless telephones, PDAs, H.320 videophones and conferencing units, voice messaging and response units, traditional computer telephony adjuncts, and any other communication device.
It should be noted that the present invention does not require any particular type of information transport medium between switch or server and first and second communication devices, i.e., the present invention may be implemented with any desired type of transport medium as well as combinations of different types of transport channels.
It should be emphasized that the particular configuration of the contact center 100 shown in FIG. 1, including all of the components thereof, is presented for purposes of illustration only and should not be construed as limiting the present invention to any particular arrangement of elements.
Referring to FIG. 2, a simplified schematic representation of the contact center 100 is illustrated (in which certain components of the contact center 100 shown in FIG. 1 are omitted for clarity) for presenting certain aspects of the contact center 100 in greater detail. Particularly, the switches 1301-4 of the contact center 100 are OpenFlow enabled switches that are operatively connected to an OpenFlow controller 160 (described in greater detail below) that receives instructions from, and may be implemented as an integral component of, the routing engine 126 of the call center 100.
As will be recognized by those of ordinary skill in the art, OpenFlow is an open communications protocol that may be added to commercial Ethernet switches, routers and wireless access points to enable certain routing control features not found in conventional routers or switches. For example, in a conventional router or switch, fast packet forwarding (data path) and high level routing decisions (control path) occur on the same device. By contrast, OpenFlow enabled switches, such as the switches 1301-4, separate data path and control path functions. Particularly, the data path portions reside on the switches 1301-4 while high-level routing decisions reside a separate controller, such as the OpenFlow enabled controller 160. The OpenFlow enabled switches 1301-4 and controller 160 communicate via OpenFlow protocol, which defines messages, such as packet-received, send-packet-out, modify-forwarding-table, and get-stats The implementation and operation of the various OpenFlow components in the contact center 100 will be described in greater detail below.
It should be noted that the switches 1301-4 and controller 160 may alternatively or additionally be enabled with any other software packages or systems (i.e., other than OpenFlow) that facilitate similar, dynamically controllable routing. Therefore, the switches 1301-4 and controller 160 will hereinafter be referred to as the “dynamic switches 1301-4” and the “dynamic controller 160,” such terminology defined herein to encompass OpenFlow enabled switches and controllers as well as switches and controllers enabled with other, similar technologies that are known in the art or that have yet to be developed.
Still referring to FIG. 2, a plurality of contacts 1701-4 are connected to the packet-switched network 162 and/or the circuit-switched network 154, such as via the 1st and 2nd contact communication devices 169 and 180 shown in FIG. 1. The packet-switched network 162 and the circuit-switched network 154 are connected to the dynamic switches 1301-4, such as via the session border controller 158 and the session manager 110 shown in FIG. 1. The dynamic switches 1301-4 route contact traffic to and from a plurality of agents 1721-7 who are equipped with the 1st and/or 2nd agent communication devices 1341-N and 1381-N shown in FIG. 1.
The dynamic switches 1301-4 are interconnected by network paths 1741-6, and are connected to the dynamic controller 160 by control channels 1761-4. The dynamic controller 160 may thereby transmit instructions to the dynamic switches 1301-4 that dictate the manner in which contact traffic is routed between the dynamic switches 1301-4 and to the agents 1721-7 in accordance with routing decisions made by the routing engine 126. In order to make such routing decisions, the routing engine 126 monitors the attributes/skill sets of all of the active agents 1721-7 (or other resources) in the contact center 100. For example, the routing engine 126 may determine which agents 1721-7 have video call capability, what languages each of the agents 1721-7 speaks, what the agents' respective areas of expertise are, etc. Additionally, by virtue of the communication between the dynamic controller 160 the dynamic switches 1301-4, the dynamic controller 160 enables the routing engine 126 to continuously monitor the states of the network paths 1741-6 between the dynamic switches 1301-4. Thus, by correlating the requirements of each contact 1701-4 (e.g., language requirements, communication device requirements, bandwidth requirements, etc.) with the attributes of available resources and the current traffic levels between the dynamic switches 1301-4, the routing engine 126 may determine the best manner in which to route contact traffic in order to most efficiently utilize contact center resources and optimize customer/contact experience.
The routing engine 126 may use the dynamic controller 160 and the dynamic switches 1301-4 to implement the above-described intelligent routing scheme in either a “passive” manner, wherein contact center resources are allocated based on the monitored state of the switch network, or an “active” manner, wherein the switch network is monitored and actively modified in order to direct traffic to contact center resources in an optimal manner.
In an illustrative, non-limiting example of a passive implementation of the contact center 100, the contact 1701 in FIG. 2 is a high priority customer who places a video call to the contact center 100 which arrives at the dynamic switch 1301. The contact 1701 may then be presented with a treatment message by the media server 118 while the routing engine 126 identifies agents 1721-7 having attributes best suited to handle the call. In this example, the agents 1721 and 1724 both have skill sets that are suitable for the contact 1701, are both equipped to handle video calls, and are both currently available, and are therefore both eligible for selection by the routing engine 126. However, the network path 1741 between the dynamic switch 1301 and the dynamic switch 1303 is currently heavily utilized and has limited available bandwidth for handling a video call without compromising call quality (i.e., audio and/or video quality).
In conventional contact centers, the state of the network paths 1741-6 would not be taken into account when selecting an agent 1721-7 to handle the contact, which could result in a suboptimal agent selection (e.g., agent 1721 is less preferable in this example because the network path 1741 leading to agent 1721 is congested and is not suitable for supporting a video call). However, in the dynamic contact center 100 of the present disclosure, the dynamic controller 160 and the dynamic switches 1301-4 enable the routing engine 126 to monitor the state of the network paths 1741-6 as described above, and to therefore make an informed routing decision in view of current system loads.
In the present example, the routing engine 126 would utilize the dynamic controller 160 and the dynamic switches 1301-4 to route the contact 1701 to the agent 1724 (i.e., via the less congested network path 1745 between dynamic switch 1301 and dynamic switch 1304) instead of to the agent 1721, thereby providing the contact 1701 with a higher quality video call and a better customer experience. The agent 1724 in this scenario may therefore be termed the “optimal resource,” selected from a plurality of suitable resources. However, if the contact 1701 was a low priority contact and/or did not require a great deal of bandwidth for a suitable connection (e.g., if the contact 1701 was a voice call), the routing engine 126 might utilize the dynamic controller 160 and the dynamic switches 1301-4 to route the contact 1701 to the agent 1721, thereby leaving the agent 1724 available for contacts who have higher priority and/or require greater bandwidth connections. The “optimal resource” in such a scenario would therefore be the agent 1721. 
In an illustrative, non-limiting example of the active implementation of the contact center 100, the contact 1701 in FIG. 2 is again a high priority customer who places a video call to the contact center 100 which arrives at the dynamic switch 1301. As in the passive implementation example above, the contact 1701 may then be played a treatment message by the media server 118 while the routing engine 126 identifies an agent 1721-7 who is best suited to handle the call. In this example, only the agent 1721 is available and has the skill set and equipment necessary for handling the requirements of contact 1701. However, as in the example above, the network path 1741 between the dynamic switch 1301 and the dynamic switch 1303 is currently heavily utilized and has limited available bandwidth for handling a video call without compromising call quality.
In conventional contact centers, the contact 1701 might be routed to the agent 1721 via the network path 1741, despite the heavy congestion thereof, due to a static, preconfigured routing scheme. However, in the dynamic contact center 100 of the present disclosure, the dynamic controller 160 and the dynamic switches 1301-4 enable the routing engine 126 to dynamically modify the route between a contact and a specific resource in view of system loads. In the present example, the routing engine 126 would utilize the dynamic controller 160 and the dynamic switches 1301-4 to route the contact 1701 to agent 1721 via the less congested network paths 1745 and 1742 (or network paths 1744 and 1745) instead of the highly congested network path 1741, thereby providing the contact 1701 with a higher quality call and a better customer experience. The network paths 1745 and 1742 in this scenario may therefore be termed the “optimal route,” selected from a plurality of suitable routes.
However, if the contact 1701 was a low priority contact and/or did not require a great deal of bandwidth for a suitable connection, the routing engine 126 might utilize the dynamic controller 160 and the dynamic switches 1301-4 to route the contact 1701 to the agent 1721 via the network path 1741, thereby leaving the less congested network paths 1745 and 1742 available for contacts who have higher priority and/or require greater bandwidth connections. The “optimal route” in such a scenario would therefore be the network path 1741.
Referring to FIG. 3, a flow diagram illustrating an exemplary method for implementing the above-described passive routing scheme of the self-configuring dynamic contact center 100 in accordance with the present disclosure is shown. Such method will now be described in conjunction with the schematic representation of the contact center 100 shown in FIG. 2.
At a first step 300 of the exemplary method, a contact 1701-4 may initiate communication with the contact center 100, such as via the 1st and 2nd contact communication devices 169 and 180 shown in FIG. 1. The contact 1701-4 may then, at step 310, be received at one of the dynamic switches 1301-2. At optional step 320, a treatment message provided by the media server 118 may be presented to the contact 1701-4.
At step 330 of the exemplary method, the routing engine 126 may determine which of the active agents 1721-7 are best suited to handle the contact 1701-4 based on the attributes, skill sets, and availability of the agents 1721-7. The routing engine 126 may then, at step 340, use the dynamic controller 160 to query the dynamic switches 1301-4 to determine the traffic loads (e.g., queues) on the network paths 1741-6.
At step 350 of the exemplary method, the routing engine may correlate the requirements of the contact 1701-4 (e.g., language requirements, communication device requirements, bandwidth requirements, etc.) the traffic loads on the network paths 1741-6 in order to determine which of the suitable agents 1721-7 is an optimal resource that the contact 1701-4 should be routed to in order to most efficiently utilize the network paths 1741-5 while providing the contact 1701-4 with a high quality experience.
For example, if the contact 1701-4 is a video call that requires high bandwidth for a robust, high quality connection, the routing engine 126 may determine that the contact 1701-4 should be routed to a suitable agent 1721-7 that is accessible via a route that has a low level of traffic and high available bandwidth. Conversely, if the contact 1701-4 is a voice call that does not require a great deal of bandwidth, the routing engine 126 may determine that the contact 1701-4 should be routed to a suitable agent 1721-7 that is accessible via a more congested route, thereby leaving less congested routes available for contacts requiring high bandwidth connections.
At step 360, the routing engine 126 may utilize the dynamic controller 160 and the dynamic switches 1301-4 to route the contact 1701-4 to the optimal resource identified in step 350.
Referring to FIG. 4, a flow diagram illustrating an exemplary method for implementing the above-described active routing scheme of the self-configuring dynamic contact center 100 in accordance with the present disclosure is shown. Such method will now be described in conjunction with the schematic representation of the contact center 100 shown in FIG. 2.
At a first step 400 of the exemplary method, a contact 1701-4 may initiate communication with the contact center 100, such as via the 1st and 2nd contact communication devices 169 and 180 shown in FIG. 1. The contact 1701-4 may then, at step 410, be received at one of the dynamic switches 1301-2. At optional step 420, a treatment message provided by the media server 118 may be presented to the contact 1701-4.
At step 430 of the exemplary method, the routing engine 126 may determine which of the active agents 1721-7 is best suited to handle the contact 1701-4 based on the attributes, skill sets, and availability of the agents 1721-7. The routing engine 126 may then, at step 440, use the dynamic controller 160 to query the dynamic switches 1301-4 to determine the traffic loads (e.g., queues) on the network paths 1741-6.
At step 450 of the exemplary method, the routing engine 126 may determine, from the traffic loads on the network paths 1741-6, an optimal route between the contact 1701-4 and the best suited agent 1721-7 (identified in step 430) that will efficiently utilize the network paths 1741-5 while providing the contact 1701-4 with a high quality experience. For example, if the contact 1701-4 is a video call that requires high bandwidth for a robust, high quality connection, the routing engine 126 may determine that the contact 1701-4 should be routed to the best suited agent 1721-7 via a route that has a low level of traffic and high available bandwidth. Conversely, if the contact 1701-4 is a voice call that does not require a great deal of bandwidth, the routing engine 126 may determine that the contact 1701-4 should be routed to the best suited agent 1721-7 via a more congested route, thereby leaving less congested routes available for contacts requiring high bandwidth connections.
At step 460, the routing engine 126 may utilize the dynamic controller 160 to reconfigure the dynamic switches 1301-4 to route the contact 1701-4 to the best suited agent 1721-7 via the optimal route identified in step 450.
