`
`CROSS-REFERENCE TO RELATED
`APPLICATIONS
`0001. This application is a continuation-in-part applica
`tion of U.S. patent application Ser. No. 08/955,834, filed on
`Oct. 21, 1997.
`
`TECHNICAL FIELD
`0002 This invention relates to computer telephone inte
`gration (CTI) and, more specifically, to an improved method
`and apparatus for utilizing CTI techniques to proceSS tele
`phone calls using various applications in a packet Switched
`telephone network.
`
`BACKGROUND OF THE INVENTION
`0.003 Telephony over packet networks, particularly over
`wide area networkS Such as the Internet, has received
`considerable attention in recent months. Specifically, Scien
`tists have begun exploring the possibility of Sending voice
`and Video information Streams over packet Switched data
`networks. The transmission of Such information Streams
`over packet Switched networks can be more cost efficient
`than traditional telephony, which requires a dedicated circuit
`between the calling and called party.
`0004 Computer telephone integration has been widely
`applied to traditional telephony methods and apparatus, but
`has not as yet been Successfully applied to the methods and
`apparatus used for packet network telephony. This invention
`Specifies novel apparatus and methods, Supplementary to
`known packet network telephony apparatus and methods,
`which enable CTI capabilities in such an environment, and
`use them to proceSS telephone calls.
`0005 One possible set of methods and apparatus for
`completing calls over a packet Switched network, which
`calls can handle Voice and other information Streams, is
`defined by ITU recommendation H.323. The H.323 standard
`is available from the International Telecommunication
`Union, of Geneva, Switzerland, and is hereby incorporated
`herein by this reference. The H.323 standard defines various
`protocols dealing with call control, call Setup, call termina
`tion, and other Similar techniques known to those in the
`packet network telephony art.
`0006. The H.323 standard defines a functional entity
`called a gatekeeper. The gatekeeper handles network func
`tions Such as bandwidth control, Zone management, address
`translation, and admissions control for a designated Set of
`network terminals. While all these functions are further
`defined in the previously incorporated Standard, we set forth
`two examples below.
`0007 Bandwidth control provides a protocol by which
`the gatekeeper allocates a particular amount of network
`bandwidth to a particular connection. The gatekeeper can be
`contacted by either the calling or called party in order to
`change the amount of bandwidth allocated to a particular
`call.
`0008. As another example, the gatekeeper performs Zone
`management. This function, as further defined in the H.323
`
`Standard, provides a mechanism for allocating Sets of dif
`ferent terminals and other nodes in the network to a par
`ticular gateway. The H.323 Standard provides a mechanism
`for dynamically altering the allocation of different network
`nodes to different gatekeeperS.
`0009. The gatekeeper function provides services analo
`gous to the call processing function within a private branch
`exchange (PBX) in conventional telephony. In traditional
`telephony, CTI features are provided by creating an interface
`between external application Software and the call process
`ing function within the PBX. By contrast, in the known
`packet network telephony art, interfaces to the gatekeeper
`are only defined from other gatekeepers, end points, and
`other network entities.
`
`SUMMARY OF THE INVENTION
`0010. The above and other problems of the prior art are
`overcome and a technical advance is achieved in accordance
`with the present invention which relates to a packet network
`telephony call controller (e.g., an H.323 gatekeeper) which
`is arranged to interface with a plurality of external call
`processing applications programs which may be located on
`one or more remote computers. In accordance with the
`teachings of the present invention, a call processing appli
`cation computer is connected to a call controller computer,
`via a data network or otherwise, and these two entities
`eXchange messages in the manner Specified by the invention.
`The call controller computer may be located with one of the
`terminals or may be located on a separate computer.
`0011 AS well, the processing application computer may
`be located with the call controller computer, or remote from
`it.
`0012. The call controller computer and applications com
`puter(s) communicate with one another in order to perform
`various call control and other call processing application
`functions over the data network and to provide call infor
`mation and control to a user of the applications computer. AS
`packet Switched telephone connections are Set up between
`various terminals or other nodes, the call controller com
`municates with one or more application computers in order
`to provide the call information and call control functions
`required by the computer telephony applications residing on
`the application computers. Examples of these functions
`include establishing and tearing down calls, transferring
`calls, call conferencing, asSociating the applications com
`puter with one or more specific end points in the call
`controller Zone for monitoring and control, determining the
`State of calls at a given endpoint, determining the length of
`calls in progreSS at a given endpoint, determining the words
`eXchanged in calls in progreSS at a given endpoint, deter
`mining the originating IP address of calls in progreSS at a
`given endpoint, routing unanswered new calls terminating at
`a given endpoint to another to another endpoint, and various
`other functions.
`0013 For illustrative purposes, the invention will be
`described using Systems based upon the H.323 Standard as
`an example. It is understood that the invention is intended to
`cover any and all other protocols, now known or to be
`known in the art, which address packet telephony, Such as,
`for example, ITU H.248, also known as MEGACO, Session
`Initiation Protocol (“SIP”), and Media Gateway Control
`Protocl (“MGCP”). These protocols describe equivalent

`
`modules which are responsible for call Setup, and are thus
`functionally equivalent, within the context of the invention,
`to the gatekeeper of H.323. The names of these modules, of
`course, vary with the given protocol. For example, in SIP the
`gatekeeper functionality is accomplished by what is termed
`a “proxy”, in MEGACO by a “Media Gateway Controller”,
`and in MGCP by a “softswitch.” Like the Shakespearean
`rose, a gatekeeper by any other name is just as Sweet.

`
`DETAIL DESCRIPTION OF THE PREFERRED
`EMBODIMENT
`FIG. 1 illustrates an overview of the interconnec
`0.018
`tion of the gatekeeper computer 102 with the applications
`computer 103 according to the teachings of the present
`invention. To enable Such interconnection, gatekeeper com
`puter 102 is enhanced and extended by the addition of
`Software whose functions are described below. Communi
`cations path 105 may be any type of data communications
`path.
`0019. The arrangement of FIG. 1 includes several exter
`nal telephony applications Systems 104, typically imple
`mented as Software, which may be located on applications
`computer 103 or on Separate computers connected via any
`communications network to applications computer 103.
`Typically, the applications computer may be collocated with
`one of the end points described below.
`0020. The arrangement of FIG. 1 also includes end
`points 106, which may be personal computers, network
`computer devices (NCS), or any other node capable of
`interconnection to the packet network telephony environ
`ment.
`0021. In operation, a command is issued from an appli
`cations computer 103 requesting certain telephony Services
`which will be described below. The message requesting Such
`a Service is transmitted through path 105 to gatekeeper
`computer 102 for processing. The message Sent to gate
`keeper 102 causes gatekeeper 102 to exchange appropriate
`Signaling messages with other packet network telephony
`environment nodes in a manner as described, for example, in
`the incorporated H.323 Standard. As a result of this sequence
`of events, the combined System is able to implement the call
`processing functionality requested by applications computer
`103 on behalf of applications 104.
`
`0022. During operation, various call control functions
`requested by applications computer 103 are performed by
`the gatekeeper 102. Additionally, by making appropriate
`requests of gatekeeper 102, applications computer 103 may
`monitor the outcome of various call control functions and
`transmit Such outcome to any of applications 104.
`0023 FIG. 2 shows an exemplary message flow diagram
`for detecting an inbound call from a remote end point to a
`local end point Supervised by an external computer tele
`phony application using the present invention. The Specific
`example shown in FIG. 2 is the monitoring of an incoming
`call to end point 202 using packet network telephony
`methods and apparatus as described in the H.323 Standard,
`enhanced by the present invention to permit the participation
`of an external Software application 201. End points 202 and
`204 represent audio terminals, for example, computer Sys
`tems equipped as H.323 compliant telephone devices. Gate
`keeper 203 is as described, for example, in the H.323
`Standard and as further enhanced by the present invention,
`and the external application 201 may be present on a
`Separate computer as previously discussed.
`0024.
`In operation, the call initially proceeds according to
`the methods of the packet network telephony environment.
`Abandwidth request message 205 is sent to gatekeeper 203
`and bandwidth is granted by the gatekeeper at message 206.
`A call Setup request, message 207, is issued by the initiating
`end point 204, and gatekeeper 203 causes call Setup request
`message 208 to be transmitted to receiving end point 202. A
`call proceeding message 209 is transmitted by the receiving
`end point back to gatekeeper 203 and relayed to initiating
`end point 210 as shown.
`0025. At approximately the same time gatekeeper 203
`relays the call proceeding indication to the initiating end
`point using message 210, gatekeeper 203 also transmits to
`external application 201 a notification that an inbound call is
`being received by the receiving end point 202. Gatekeeper
`203 sends this message because external application 201 has
`previously indicated that it requires notification of telephony
`events occurring at receiving end point 202.
`0026. In order to connect the inbound call, receiving end
`point 202 requires network bandwidth, and such bandwidth
`is requested from and allocated by the gatekeeper 203 using
`messages 212 and 213. Next, the terminal at monitored end
`point 202 rings to alert the user to the arriving call, and an
`indication of Such ringing is transmitted through messages
`214 and 215 to initiating end point 204 through the gate
`keeper 203. When the call is connected at the receiving end
`point 202 because of user action, end point 202 informs
`gatekeeper 203 via message 216.
`0027. At this point, gatekeeper 203 sends an answer
`notification to the external application 201 via message 217.
`0028. At approximately the same time, gatekeeper 203
`indicates to the initiating end point 204 that the requested
`call has been connected via message 218.
`0029. In accordance with the protocol described herein
`before, the detection of the call by an external application is
`accomplished via a protocol of messages transmitted
`between the gatekeeper and the end points to be connected,
`as well as between the gatekeeper 203 and the external
`application 201, thus enabling gatekeeper 203 to inform

`
`external application 201 regarding the progreSS of relevant
`calls in the packet telephony network.
`0030 FIGS. 3A and 3B show another example of an
`external call processing application requesting the establish
`ment of an outbound call from initiating end point 386 to
`receiving end point 390. Many of the messages involved in
`this operation are Substantially similar to those previously
`set forth with respect to the monitoring of the inbound call
`described in FIG.2. New messages not previously discussed
`in FIG. 2 are described below. As with the discussion of
`FIG. 2, the external application 392 in FIGS. 3A and 3B is
`assumed to have previously communicated with gatekeeper
`388 in accordance with other methods described by this
`invention to indicate its intention to issue call control
`requests with respect to initiating end point 386.
`0031. In FIGS. 3A and 3B, gatekeeper 388 also includes
`the conference control point function as currently known to
`the packet network telephony art. This function is used by
`the invention to interconnect two call Segments, namely the
`Segment between the initiating end point 386 and the con
`ference control point; and between the conference control
`point and the receiving end point 390. The invention con
`nects the call in two stages in order to overcome certain
`limitations of the known packet network telephony art. For
`clarity of description, the combined gatekeeper and confer
`ence control point apparatus is referred to as a gatekeeper
`388.
`0.032 The sequence of messages begins with a new
`message 301, specified by the current invention, through
`which the external application 392 makes a request that the
`first segment of the call be established from gatekeeper 388
`to initiating end point 386.
`0.033
`Next, according to known packet network tele
`phony art, messages 302 and 303 are exchanged between
`gatekeeper and initiating end point 386 in order to Set up that
`first leg of the call.
`0034) Next, the gatekeeper 388 sends a new message 304
`to external application 392 to alert it that the call request has
`been received and is being processed. Much of the remain
`ing Signaling, relating to the establishment of that Segment
`of the call between initiating end point 386 and gatekeeper
`388 in FIGS. 3a and 3b, is substantially similar to that
`previously described with respect to FIG.2 and thus will not
`be repeated. Similarly, once the first leg of the call has been
`Set up, gatekeeper 388 proceeds in Similar fashion to Set up
`the Second leg of the call from itself to receiving end point
`390.
`0035). However, during the process depicted in FIGS. 3A
`and 3B gatekeeper 388 sends new messages to the external
`application 392 at relevant Stages of call processing, includ
`Ing:
`
`0036 1. Message 305 indicating that initiating end
`point 386 has acquired the necessary network band
`width to place the call;
`0037 2. Message 306 indicating that receiving end
`point 390 is processing the request for the call;
`0038. 3. Message 310 indicating that receiving end
`point 390 is alerting its user to the arriving call; and
`0039 4. Message 312 indicating that receiving end
`point 390 has answered the call and a connection has
`been established.
`
`0040 FIG. 4 shows various possible connections for the
`gatekeeper computer-processing application computer link.
`A gatekeeper computer 410 facilitates calls between the
`various H323 or equivalent endpoints 406. As an example,
`these endpoints can be connected to telephones 420 via
`PSTNS 421. Alternatively, the endpoints can be connected to
`other computers or devices, such as PBXs 481, which then
`interface to, as an example, cellular networks 480.
`0041) The processing application computers (AC) 430
`are connected to the gatekeeper computer (GK) 410 in a
`variety of ways, Some of which are shown as examples in
`FIG. 4. The gatekeeper computer Sets up and controls call
`sessions between the various H.323 or equivalent endpoints
`406.
`0042. One or more ACS 430 can be connected to the GK
`410 via a LAN 473, a generic data network 472, or via
`interprocess Software communication 471, where both the
`GK and AC are Software modules on the same physical
`computing device, shown via the dotted line box 490 drawn
`around these components connected via the interprocess
`Software communication 471.
`0043 Alternatively, the AC 4301 and GK 410 can be
`themselves connected via the Internet 450, or other com
`puter communications network. Or, the GK 410 could write
`to a file, stored, and then itself transmitted to an AC 430, via
`a variety of data transmission channels, as described above,
`or as is otherwise known in the art.
`0044) The ACS 430, communicating with the GK in an
`analogous fashion as described above, can implement, via a
`variety of applications programs, applications and Services
`Such as Voice recognition of the words exchanged in the call,
`rerouting the call if unanswered after a determined number
`of rings, measurement of the length of the call, and Storing
`the word content of calls as determined by the above
`described Voice recognizer and writing Such content to a file
`for analysis by another program, to list a few. AS described
`above these applications are usually implemented in Soft
`ware, but could be implemented, wholly or partially, in
`dedicated hardware as well, especially in complex applica
`tions requiring a lot of processing.
`004.5 The method of the invention relates to software
`functional modules, and holds constant no matter what the
`physical arrangement of those modules might be. For
`example, two modules as described above (for example, the
`Application Computer and the Gatekeeper) might reside on
`Separate computing Systems or may reside on a common
`System; they nonetheless remain Separate modules and com
`municate with each other in a similar fashion. Thus, the
`invention is intended to include any Such rearrangement of
`Software modules on a convenient Set of computing Systems.
`0046) The communication methods described above are
`as well intended to includea wide variety of possible imple
`mentations. Thus, for example, two modules residing in a
`common computing System will eXchange messages, but
`may not do So over a physical “data network” in the Sense
`of Signals travelling over external wires.
`0047 There are various methods by which an application
`(running on the application System) actually requests the
`services available over the CSTA-like link (CSTA being the
`standard abbreviation for Computer Supported Telecommu
`nication Applications). One common method is to provide a
`
`IPR2018-00884

`
`Standard Software library on the application machine that
`offers a telephony Application Programming Interface
`(“API”) to the application program. Within the context of the
`invention, this API can be any API that includes call-control
`functions. Two such APIs known to the industry are, for
`example, Microsoft's TAPI (“Telephony API”) and Sun's
`JTAPI (“Java Telephony API”). The APIs are used to pro
`vide convenient access by the application program to the
`services delivered by the invention.
`0.048. There are many possible applications that could
`make use of the capabilities of the invention. These appli
`cations are well known and for the sake of brevity will not
`be exhaustively described herein. Some of the more likely
`applications are the following:
`0049 Call Routing. When a request to handle an incom
`ing call is presented to the call controller (or "gatekeeper” in
`H.323 parlance), the gatekeeper sends a message to the
`application requesting routing instructions. The application
`uses any convenient busineSS logic to decide how the call
`should be routed, and responds to the gatekeeper with
`appropriate instructions. The gatekeeper then routes the call
`to a destination based on those instructions. Several
`examples of Such busineSS logic would include, as examples,
`follow me Services, load balancing, skill based routing,
`Screen pop, universal queueing and unified messaging, each
`of which is summarily described in what follows.
`0050. Follow-me services. A telephone subscriber leaves
`forwarding instructions with the application Specifying the
`telephone endpoint or series of endpoints to which calls
`should be forwarded, and optionally Some rules that govern
`that forwarding. For example, “calls arriving between cer
`tain times of day should be forwarded to this number”; or “I
`am in my car now, Send all calls to my cell phone', or
`“Forward all calls to my voicemail except calls from my
`boss and my children”.
`0051 Load balancing. When a call is made to an enter
`prise and it is determined that any of Several individuals,
`offices or work groups could handle Such a call (for example,
`a call to a customer Service number), the application can
`choose which individual, work group or office should
`receive te call based on its assessment of the current work
`load at each potential destination.
`0.052
`Skill-based routing. When a call is made to an
`enterprise and it is determined that any of Several individu
`als, offices or work groups could handle Such a call (for
`example, a call to a customer Service number), the applica
`tion can choose which individual, work group or office
`should receive the call based on its assessment of the
`capabilities required by the caller (for example, knowledge
`of a particular product or account type, or ability to Speak a
`certain language).
`0.053 Screen pop. When a call is directed to a particular
`endpoint, the gatekeeper Simultaneously alerts the applica
`tion So that the application can retrieve business information
`corresponding to the call (for example, customer or account
`information) and display it for the user at that endpoint.

`Universal Queueing. When an application manages
`multiple forms of communications for a user (for example,
`traditional or packet telephone calls, electronic mail mes
`Sages, facsimile documents, communication requests from
`parties viewing web pages, text chat Sessions) by Sequencing
`
`those communications So that they are Served in an equitable
`and/or efficient fashion, that application can use the inven
`tion to acquire the necessary information about packet
`telephony calls and to direct the holding and release of Such
`calls as may be required to implement the desired Sequenc
`Ing.
`0055 Unified Messaging. When an application manages
`multiple forms of Store-and-forward communications for a
`user (for example, electronic mail messages, voice mail
`messages, facsimile documents) by Storing these communi
`cations, presenting an inventory of those communications to
`the user, and presenting Specific Selected messages to the
`user as directed by that user, that application can use the
`invention to create packet telephony connections between
`the message repository and the user for the purposes of
`presenting Said inventory to the user, allowing the user to
`give Said direction, and presenting the Selected messages.
`0056. The above describes the preferred embodiments of
`the invention. It will be appreciated however that various
`other modifications or additions will be apparent to those of
`ordinary skill in the art.
