2. Description of Related Art
With today's widespread use of the Internet as a major communication medium, data communication devices are now being designed so that they are capable of communicating over packet-switched networks. For instance, telephones, pagers, personal digital assistant devices, cell phones, handheld computers, and even fax machines can now be accessed and controlled from the Internet. Communication over a packet-switched network using communication devices that traditionally communicate over a circuit-switched telecommunications network is generally known as network telephony, or IP telephony when an IP network is involved.
Various types of user communication devices (e.g., a cell phone, laptop or handheld PC, desktop PC, and the like) can identify themselves to the network using a suitable identifier (e.g., username@company.com). “Presence” refers to, for example, the availability, proximity, activity level or operating state of a user or device on a network. The ability for users to monitor each other's presence is a feature offered in connection with many applications that support network telephony. For example, instant messaging (IM) applications such as MSN®, Yahoo®, et cetera, have an “available buddy” feature, in which a user of the application can determine whether select users are available for engaging in communication. The data retrieved and returned to the buddy list, e.g. “John OFFLINE” or “Susan ACTIVE”, is known as “presence information,” and is generally maintained by a presence server in the data network, often a dedicated server. Typically, the presence server supports network protocols such as the Session Initiation Protocol (SIP). Users can register their communication devices with the presence server in order to have their presence maintained and to allow various programs on the network to facilitate network telephony services. A first device user wishing to detect the presence of a second device user does so by “subscribing” with the presence server, such as via a SIP SUBSCRIBE message. The presence server intermediates between the first device user (also known as the watcher or subscriber) and the second device user to facilitate the communication of the second device user's presence information to the first device user.
Additional details concerning presence and presence data modeling are set forth in the Internet Engineering Task Force (IETF) Request for Comment (RFC) 2778 entitled “A model for Presence and Instant Messaging,” dated February 2002; RFC 2779 entitled “Instant Messaging/Presence Protocol Requirements,” dated February 2002; and Internet-Draft identified as <<draft-schulzrinne-simple-rpids-01.ps>> and entitled “RPIDS—Rich Presence Information Data Format for Presence Based on the Session Initiation Protocol (SIP),” dated Feb. 18, 2003, which are incorporated herein by reference.
Although presence applications have been implemented in a variety of settings such as those exemplified hereinabove, several areas remains deficient in terms of presence and customization of call treatment using presence information.
According to one embodiment, an IM-based call treatment (IMBCT) system and method operable in a communications network environment is disclosed. Upon establishing presence awareness among a plurality of networked entities, a call treatment profile having a number of treatment options is provided for a particular networked party based on presence information. When an incoming communication request intended for the particular networked party is received and that particular networked party is unavailable, a IMBCT functionality is operable to forward an IM that includes call treatment options to the calling party. Upon selection of a specific treatment option by the calling party, a treatment is provided relative to the communication request responsive to the selection.
In one aspect, the present invention is directed to a routing method based on call treatment options provided in a communications network environment. Initially, presence awareness is established among a plurality of networked parties, wherein each party is provided with a first communication device operably coupled to a first network and with a second communication device operably coupled to a second network, the second network operating to facilitate communication of presence information relating to the networked parties. A call treatment profile is provided with respect to an incoming communication request for a particular networked party based on the presence information. Upon receiving a communication request from an originating party, e.g., a customer requesting service from a call center, over the first network, wherein the communication request is intended to be directed to the particular networked party, an instant message is generated to the originating party that includes at least a portion of the call treatment profile having a number of options. A response is generated by the originating party that is responsive to the instant message, whereupon a particular call treatment is provided relative to the communication request based on the response. In one embodiment, the response by the originating party includes providing a reply instant message by the originating party to the particular networked party, wherein the reply instant message comprises a selected call routing option relative to the communication request, e.g., selecting another networked party that has been established as a contact for the particular networked party.
In another aspect, the present invention is directed to a routing system based on call treatment options provided in a communications network environment. A suitable presence application is provided for establishing presence awareness among a plurality of networked parties, wherein each party is provided with a first communication device operably coupled to a first network and with a second communication device operably coupled to a second network, the second network operating to facilitate communication of presence information relating to the networked parties. A database and logic structure module is provided for supporting a call treatment profile for a particular networked party based on the presence information, wherein the call treatment profile includes a list of contacts selected from at least a portion of remaining networked parties. Logic structure is included for generating an instant message to an originating party that includes at least a portion of the call treatment profile, upon receiving a communication request from the originating party over the first network wherein the communication request is intended to be directed to the particular networked party that is unavailable. Responsive to a response message generated by the originating party, routing logic structure is operable for providing a treatment relative to the communication request. In one embodiment, the response message by the originating party includes providing a reply instant message by the originating party to the particular networked party, wherein the reply instant message comprises a selected call routing option relative to the communication request, e.g., selecting another networked party that has been established as a contact for the particular networked party. The routing logic structure accordingly provides a command to a network switch in order for forwarding the communication request to the selected contact.
In yet another aspect, the present invention is directed to a system for routing calls based on treatment options provided via instant messaging. A plurality of phones are interconnected to form a phone network, e.g., an enterprise phone network, wherein a select phone is provided with an instant messaging call treatment function that transmits an instant message to a caller when the select phone is set to an unavailable status, the instant message including a set of call treatment options relative to an incoming call from the caller. A routing manager is provided that is operable responsive to a reply instant message generated by the caller, the reply instant message including a particular call treatment option selected by the caller, wherein a forwarding command is provided by the routing manager to a switch associated with the phone network in accordance with the particular call treatment option selected by the caller.
The accompanying drawings are incorporated into and form a part of the specification to illustrate one or more presently preferred exemplary embodiments of the present invention. Various advantages and features of the invention will be understood from the following Detailed Description taken in connection with the appended claims and with reference to the attached drawing figures in which:
Embodiments of the invention will now be described with reference to various examples of how the invention can best be made and used. Like reference numerals are used throughout the description and several views of the drawings to indicate like or corresponding parts, wherein the various elements are not necessarily drawn to scale. Referring now to the drawings, and more particularly to
At the outset, it should be realized by those skilled in the art that for purposes of the present invention, the first and second networks may comprise any known or heretofore unknown telecommunications or data communications networks, either private or public, as long as one of them, e.g., the second network 104, is capable of operating as a presence-aware network. Accordingly, the first network 102 can be a network selected from the group consisting of an enterprise communications network, e.g., a digital Private Branch Exchange (PBX) network, at least a portion of a public circuit-switched voice communications network such as the Public Switched Telephone Network (PSTN), or a packet-switched network, e.g., an Internet Protocol (IP)-based network. In terms of the type of communications that can be supported, it is envisaged that the first network 102 is capable of supporting voice communications, video communications, data communications, text message communications, electronic mail (email) communications, multimedia communications, or any combination or combinations thereof. As a consequence, the term “call” or “communication request” used in reference to a communication event initiated by the originating party 103 should be construed broadly and can include any communication event relating to the communication types exemplified herein (e.g., voice calls, video calls, text messages, email messages, video mail messages, multimedia calls, et cetera). Correspondingly, the first communication devices 108-1 to 108-N associated with the networked parties may comprise wireline telephones, wireless telephones, PBX digital phones, video phones, text messaging devices, Voice-over-IP (VoIP) or web phones, and the like, depending on particular network implementation and application.
As alluded to in the foregoing, the second network 104 is preferably operable as a presence-aware network wherein presence information relating to the networked parties and associated communication devices may be collected and shared using any presence-capable network protocol. By way of example, the second network may be implemented as an IP-based network that is operable with a presence application protocol selected from the group consisting of SIP, Extensible Messaging and Presence Protocol (XMPP), IBM Sametime protocol, and so on. Furthermore, the second network 104 may comprise a local area network, wide area network, an enterprise intranet network, or a public packet-switched network such as the Internet. Accordingly, the second communication devices 110-1 to 110-N associated with the networked parties may comprise a computing/communication device such as, e.g., a desktop or laptop personal computer, although any hardware platform operable with a presence application may be provided as part of the second network 104 within the context of the present invention. Additionally, in a further embodiment, the first and second communication devices associated with a networked party may be integrated into a single device, e.g., equipment that supports computer telephony integration (CTI), with which the networked parties may access both first and second networks. For instance, additional details regarding integration of PBX phones and presence-capable computer equipment may be found in the following co-pending commonly assigned United States nonprovisional patent application entitled: “CLIENT-BASED INTEGRATION OF PBX AND MESSAGING SYSTEMS,” application Ser. No. 10/750,795, filed Dec. 31, 2003, in the name(s) of Michael S. Wengrovitz, cross-referenced hereinabove.
To facilitate presence information collection and sharing, a presence server 114 may be provided as part of the second network 104. In one embodiment, the presence information relates to the presence state/data of the networked parties and associated communication devices (e.g., “OFFLINE”; “ONLINE”; “OUT TO LUNCH”; “BUSY”; “IDLE”; “ON PHONE”; “IN CONFERENCE”; “WITH CUSTOMER”; “KEYBOARD INACTIVE”; “CALL WAITING”; “OFF-HOOK”; “RINGING”, et cetera) that is helpful in determining whether a networked party or its communication device is available for establishing a connection with respect to an incoming communication request generated by the originating party 103. As will be seen in detail below, such presence information may determine various call treatment options that may be provided as part of a call treatment profile associated with a particular networked party. IM-based call treatment (IMBCT) logic may be provisioned in the communications network environment 100 either in a centralized manner (e.g., as a separate network node or as a co-located module associated with a network switch or a presence server) or by way of a distributed arrangement wherein the IMBCT logic may be partitioned across one or more network entities, i.e., communication devices associated with the networked parties, or in any combination thereof. As shown in
Regardless of where or how the IMBCT logic is provisioned in the communications network environment 100, the logic is operable to facilitate the generation of an IM that includes a number of call treatment options with respect to any incoming communication request, mediated through presence information as well as user preferences and options. In one embodiment, the IMBCT logic is operable responsive to an incoming communication request that is intended to be directed to a particular networked party (e.g., NP-1106-1) that is unavailable for some reason. When it is detected or designated that NP-1106-1 is busy or otherwise unavailable, the IMBCT logic generates an IM towards the originating party, which IM includes a plurality of treatment options selectable by the originating caller party. Also, a set of user preferences configurably associated with NP-1106-1 may be interfaced with the IMBCT logic so as to further refine the various treatment options that may be provided as part of the IM to the originating party. By selecting a particular treatment option, which is transmitted back to the IMBCT logic in a response message, the originating party can therefore influence how its call may be treated within the communications network environment 100. Responsive to the response message from the originating party, which can be a reply IM in one embodiment, the IMBCT logic provides appropriate signaling so that a call treatment is effectuated relative to the communication request. For example, the originating party may select a call forwarding option whereby the communication request is to be forwarded to a contact established as part of the treatment profile of the intended particular networked party, i.e., NP-1106-1. Those skilled in the art will readily recognize that the re-routing process may be facilitated via one or more switching nodes associated with the first network 102 (e.g., a PBX in an enterprise network such as a call center network) over which the communication request is received, although the communication request may have been originated in a separate network altogether. Additionally, it should be further appreciated that the overall IMBCT functionality in conjunction with contact selection and/or user preference mediation is amenable to numerous applications, configurations, modifications, enhancements, et cetera. As a simple example, the user preferences associated with NP-1106-1 may be predetermined or dynamically defined, and may comprise call treatment options based on the contents/type/nature of the incoming communication request, day/date/time stamp information of the request, identity of the originating party, and so on. Determination of contact members for NP-1106-1 may be effectuated automatically or manually, and a suitable contact selection logic may be employed that involves multi-level resolutions resulting in a hierarchical, prioritized decision-making process. Additional details, for instance, regarding selection of multiple contacts among a plurality of networked entities may be found in the following co-pending commonly assigned United States nonprovisional patent application entitled: “PRESENCE-BASED ROUTING IN A COMMUNICATIONS NETWORK ENVIRONMENT,” filed ______, Attorney Docket No. 1285-0145US, in the name(s) of: Timucin Ozugur and Michael S. Wengrovitz, cross-referenced hereinabove.
A IMBCT module 210 includes a routing logic function 212 that is operably coupled to an instant messaging (IM) module 216 (e.g., representative of known IM applications operable to provide IM services), a contact list or database 218 and a database of user preferences and options 214. As alluded to in the foregoing discussion, the contact selection logic 216 may be dynamically configurable, and can involve real-time input from the user (i.e., the networked party intending to re-route communication requests). In addition, the user preferences/options database 214 and contact list database 218 may be populated, updated, and maintained in a number of ways. A display and/or user interface 222 is provided for supporting appropriate GUI-based dialog boxes and menus that facilitate user interaction.
Responsive to the selection by the originating party, a response message is generated thereby that is transmitted to the IMBCT functionality of the particular networked party. Depending on the selection, the response may include a IM-based request that the communication request be routed or re-routed to a party other than the intended particular networked party. In other instances, the originating party may simply request access to a voice recording system (e.g., an interactive voice recording (IVR) service), or may simply disconnect. Regardless, responsive to the response message by the originating party, a treatment relative to the communication request is provided, which in one case may involve forwarding the call to another party, i.e., a selected contact. These actions are consolidated at blocks 308 and 310. Also, as a further variation, another instant message may be directed to the selected contact or contacts that an incoming communication request is being routed thereto. A communication event/session pursuant to the incoming communication request may then be established between the originating party and the selected contact(s), which can be conditionally dependent upon acceptance by both parties (block 312). The communication session is subsequently terminated upon completion of the communication event (block 314).
As part of establishing presence awareness in the network, Workers publish their presence status to the presence server 408 by means of suitable messaging. In response thereto, the presence server 408 provides presence status information to the watcher, which in this scenario is Worker1410-1. As illustrated, Worker2410-2 and Worker3410-3 who provide their presence status via PUBLISH 418 and PUBLISH 422 messages are deemed to be contacts for Worker1410-1. NOTIFY messages 420, 424 are provided to Worker1410-1 by the presence server 408 for establishing presence awareness.
Thereafter, presence status associated with Worker1410-1 is set to busy (to signify unavailability) as indicated by reference numeral 426. As part of activating and configuring the IMBCT logic for Worker1410-1, appropriate call treatment profile is established therefor which includes various call treatment options that can be customized as alluded to before. Reference numerals 428 and 430 refer to these actions, respectively.
When an incoming call 432 (originated by customer 434) is received in Network-1402 for Worker1410-1, IMBCT module 416 transmits an IM 436 including the call treatment options to the originating party 434. Responsive thereto, a reply IM 438 is generated by the originating party towards Worker1410-1, which reply IM includes a call treatment selection, for example, forwarding the communication request to another party, such as Worker3410-3. Responsive thereto, a call forwarding command 439 is provided by IMBCT module 416 to the switch 406 in order to effectuate the selected call treatment option. Also, IMBCT module 416 may generate another IM 440 towards the selected contact, i.e., Worker3410-3, that a call originated by the originating party 434 is being forwarded thereto. Responsive to the call forward command 439, switch 406 effectuates the re-routing of the call to Worker3410-3 as indicated by reference numeral 442. Thereafter, a call session 444 is established between Worker3410-3 and the originating party. Subsequent to completion of the call, the call session may be terminated as indicated by reference numeral 446.
Based on the foregoing Detailed Description, it should be appreciated that the present invention advantageously provides an IM-based call treatment mechanism that enhances caller control as well as supports customization by a called party in a networked environment. Value propositions such as efficient re-routing, servicing calls based on contact member expertise, etc., may be enabled, particularly in enterprises such as call centers and the like.
Although the invention has been described with reference to certain exemplary embodiments, it is to be understood that the forms of the invention shown and described are to be treated as exemplary embodiments only. Accordingly, various changes, substitutions and modifications can be realized without departing from the spirit and scope of the invention as defined by the appended claims.
