     BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The present invention relates to telecommunications. More particularly, the present invention relates to a telecommunications system with disparate intelligent peripherals that provide an integrated telecommunications service for a call from a calling party calling a service number. 
         [0004]    2. Background Information 
         [0005]    A need exists to aggregate the services provided by a telecommunications system with multiple disparate intelligent peripherals. For example, the functionality of one interactive voice response device may not be available on another interactive voice response device due to technical considerations. As a result, a service offered by an interactive voice response device may be unnecessarily limited because a particular function or service is unavailable, even though the function or service is available from another interactive voice response device in the telecommunications network. 
         [0006]    An intelligent peripheral may not be able to support a particular function or service because the function or service uses a protocol that is not supported by the intelligent peripheral. Furthermore, the intelligent peripheral may not have the processing ability or available memory to support a highly complex program developed long after the intelligent peripheral is produced and installed. 
         [0007]    In addition, when improvements can be made to an intelligent peripheral service, the improvements may have to be entirely provisioned for each intelligent peripheral that offers the service. A service provider may not be able to justify the costs to upgrade the functionality of every intelligent peripheral that would benefit from the new or upgraded function or service. 
         [0008]    Accordingly, a need exists for a system that integrates the services of multiple disparate intelligent peripherals. For example, an intelligent peripheral is needed that will recognize when to obtain the services of another intelligent peripheral. Additionally, an intelligent peripheral is needed for initiating communications with another intelligent peripheral so that the services of the other intelligent peripheral can be provided to a calling party. Moreover, intelligent peripherals are needed that can interact with each other in order to coordinate the services provided to a calling party. In addition, a system is needed that integrates the services of disparate intelligent peripherals using communications networks such as the public switched telephone network (PSTN) and/or an advanced intelligent network (AIN). 
         [0009]    To solve the above-described problems, a system is provided for integrating the services of multiple disparate intelligent peripherals.

A determining source code segment determines whether to contact a second intelligent peripheral based on the interaction with the calling party. A call connection initiating source code segment initiates a call by establishing a call connection with the second intelligent peripheral. The second intelligent peripheral interacts with at least one of the calling party and the first intelligent peripheral to provide the telecommunications service.

         [0029]    According to still another aspect of the present invention, the computer readable medium includes an entry forwarding source code segment that forwards an entry. The entry includes information related to the call. The entry is forwarded from the first intelligent peripheral to a session database. According to yet another aspect of the present invention, the computer readable medium also includes an update retrieving source code segment that retrieves the update from the session database and resumes interaction with the calling party after the second intelligent peripheral is disconnected from the call. 
         [0030]    According to another aspect of the present invention, the computer readable medium includes a call bridging source code segment that establishes a three way call by bridging the call between the calling party and the first intelligent peripheral with the call between the first intelligent peripheral and the second intelligent peripheral. 
         [0031]    According to an aspect of the present invention, a computer readable medium stores a program that provides a telecommunications service to a calling part using a plurality of intelligent peripherals. The computer readable medium includes a call connection initiating source code segment at a first intelligent peripheral that receives a call from a second intelligent peripheral. The first intelligent peripheral interacts with at least one of the calling party and the second intelligent peripheral to provide the telecommunications service. A call interaction source code segment at the first intelligent peripheral interacts with at least one of the calling party and the second intelligent peripheral. 
         [0032]    According to another aspect of the present invention, the computer readable medium includes an entry retrieving source code segment that retrieves an entry from a session database. The entry includes information related to interaction between the calling party and the second intelligent peripheral. 
         [0033]    According to still another aspect of the present invention, the computer readable medium includes an updated entry forwarding source code segment that forwards an updated entry to the session database. The updated entry includes information related to the interaction between the first intelligent peripheral and at least one of the calling party and the second intelligent peripheral. 
         [0034]    According to yet another aspect of the present invention, the interaction between the first intelligent peripheral and the second intelligent peripheral is an exchange of signals that include at least one of dual tone multifrequency signals, prerecorded speech and computer generated speech. 
         [0035]    A telecommunications system is provided for integrating the services of multiple disparate intelligent peripherals. The telecommunications system includes a switching network, a host intelligent peripheral and a service intelligent peripheral. 
         [0036]    The switching network may be an advanced intelligent network (AIN) that includes service switching points and service control points. A service switching point is connected to an individual communications device, such as a phone or modem. The service switching point responds to particular dialing patterns or sequences input to the individual communications device. The service switching point triggers when it detects a predetermined dialing pattern and sends a query via a signaling network to a service control point. The query to the service control point results in an instruction to forward the call from the service switching point to a host intelligent peripheral. 
         [0037]    In an embodiment, the host intelligent peripheral may correspond to a telephone number, IP address, or other destination identifier for which calls are routed through a switching network without a need to trigger a service switching point of an advanced intelligent network. Accordingly, a telephone call may be routed through the telecommunications system to the host intelligent peripheral without instruction from a service control point, even in a network where a service control point is otherwise provided. 
         [0038]    The host intelligent peripheral may be an interactive voice response device or any other type of device loaded with interactive voice response functionality. The interactive voice response functionality may include, e.g., DTMF recognition and prerecorded messages that instruct the calling party to input data by punching a keypad of the calling party&#39;s phone or speaking. The host intelligent peripheral may also include a text-to-speech processor that dynamically converts text data into audible signals that can be presented to the calling party. The host intelligent peripheral may also include a speech-to-text processor that converts audible signals from the calling party to text data that is processed by the host intelligent peripheral. An exemplary telecommunications service provided using intelligent peripherals is disclosed in U.S. patent application Ser. No. 10/200,977 to BOOK et al., filed Jul. 24, 2002, the disclosure of which is expressly incorporated by reference herein in its entirety. 
         [0039]    Speech recognition functionality, such as speech recognition software, available from, e.g., SpeechWorks, International, or Nuance Communications, may be provided at an intelligent peripheral. The speech recognition software may receive and interpret voice input from the calling party. Accordingly, an intelligent peripheral may receive and interpret voice input and touch tone DTMF signals from the calling party, as long as the intelligent peripheral has an interactive voice response capability and/or speech recognition software. 
         [0040]    The host intelligent peripheral may be a service node/intelligent peripheral that independently determines a sequence of instructions to forward to the calling party. A service node/intelligent peripheral (SN/IP) can be a computer or communications server linked to the switch via, for example, an ISDN link using either ISDN-BRI (Basic Rate Interface) or an ISDN-PRI (Primary Rate Interface) protocol, each of which is known in the art. In another embodiment, the SN/IP can be linked to the switch by, e.g., an analog line, a data line, or high-capacity trunks. A SN/IP may contain resources to offer service enhancements to calling parties of a telecommunications service provider. A SN/IP may combine computer telephony integration (CTI) and advanced speech technologies in a single platform used as a system resource. For example, a SN/IP may provide voice-print authentication, speaker verification, speech recognition, text-to-speech/speech-to-text conversion and dual-tone multi-frequency (DTMF) recognition with external telephony resources. 
         [0041]    In an embodiment, the host intelligent peripheral may provide the responses to, and receive instructions from, a service control point that processes data from the sequence of speech or dual tone multi frequency signals received from the calling party, and that determines the response to provide to the calling party. The host intelligent peripheral and the service control point communicate over a signaling network such as the SS7 network. An intelligent peripheral may internally translate data messages received from a service control point through the SR-3511 protocol, the use of which enables simultaneous compatibility with interactive voice response functionality. Details of the SR-3511 protocol are provided in Telcordia, Recommendations SR-3511 SCP Intelligent Peripheral (IP) Interface Specification for TCP/IP, Version 5.0 (January 1997), the disclosure of which is expressly incorporated by reference herein in its entirety. In an embodiment, the translation program can be coded in C, C++ or JAVA. 
         [0042]    Regardless of whether the host intelligent peripheral is self directing or under the control of a service control point, the host intelligent peripheral receives the speech and/or dual tone multi frequency signals from the calling party and provides the responses to the calling party. When, during the interaction between the calling party and the host intelligent peripheral, a determination is made that the functionality of a service intelligent peripheral should be requested, the host intelligent peripheral initiates communication with the service intelligent peripheral by, e.g., establishing another connection with the service intelligent peripheral and then bridging the two connections. The service intelligent peripheral interacts with the calling party until the functionality of the service intelligent peripheral is no longer needed. The service intelligent peripheral is disconnected and the host intelligent peripheral resumes interaction with the calling party. Accordingly, the disparate host and service intelligent peripherals are integrated to provide a service for a calling party. 
         [0043]      FIG. 1  shows an exemplary service architecture of the telecommunications system of the present invention. As shown, an individual communications device  100  is connected to a switch  105  of the public switched telephone network (PSTN). In the alternative, an individual communications device  102  may be a cellular telephone or other wireless device that communicates with the switch  105  via a cellular tower  104 . 
         [0044]    In an embodiment, a personal computer  101  may be used to connect with the switch  105  via a router  103  and an internet protocol gateway  106 . The router  106  is used to route packets according to a packet-switching protocol, e.g., transmission control protocol/internet protocol (TCP/IP). The internet protocol gateway  106  is an interface between the packet-switched network that includes the router  103  and the PSTN and/or AIN that includes the switch  105 . The personal computer  101  may be used by a calling party to route, e.g., voice over internet protocol (VOIP), packets that are converted at the internet protocol gateway  106  for transmission over a dedicated line to the switch  105 . 
         [0045]    According to an aspect of the present invention, the switch  105  is set with an originating trigger that responds to a particular dialing pattern, such as an 800 dialing pattern used for a telecommunications service provided by the host intelligent peripheral  150 . In response to the trigger, the switch  105  suspends the call and launches a Info Analyzed query to a control point  115  through signaling transfer points (not shown). 
         [0046]    The switch  105 , the signaling transfer points, and the control point  115  may be components of an Advanced Intelligent Network, as is known in the art. The switch  105  and the control point  115  may communicate with each other over a SS7 network using a standard interface protocol. In an embodiment, the interface protocol used by the switch  105  and the service control point  115  to communicate is SS7 protocol. 
         [0047]    In response to receiving the query from the switch  105  the control point  115  processes the query and transfers control to common service logic, which determines a routing solution for the call. In response to the query, the control point  115  executes its internal Called Number Identifier service logic and signals back to the inquiring switch  105  a Forward Call response with the destination routing number corresponding to the host intelligent peripheral  150 . The switch  105  forwards the call to the host intelligent peripheral  150  through a switching network. 
         [0048]    The host intelligent peripheral  150  may be an interactive voice response device or another type of intelligent peripheral device provisioned with interactive voice response functionality. Exemplary interactive voice response devices include a service node/intelligent peripheral, such as an IBM Resource Manager, a Lucent Compact Service Node or a Lucent Enhanced Media Resource Server (eMRS). The host intelligent peripheral  150  plays an introductory message to the calling party. The introductory message may include a request for the calling party to input information by speaking or pressing buttons on a keypad to generate dual-tone multi frequency (DTMF) tones. The buttons on the keypad each correspond to a distinctive DTMF tone that is received by the host intelligent peripheral  150 . 
         [0049]    The host intelligent peripheral  150  receives the information and translates speech or DTMF tones into data. In the case where the host intelligent peripheral  150  is a service node/intelligent peripheral, the host intelligent peripheral  150  independently determines the call flow. However, in the case where the call flow of the host intelligent peripheral  150  is subject to the control of a control point, the host intelligent peripheral  150  forwards the data to the control point  155 , and the control point  155  instructs the host intelligent peripheral  150  to play messages to the calling party. 
         [0050]    Accordingly, the call flow logic of the host intelligent peripheral  150  may be loaded into the host intelligent peripheral  150  if it is a service node/intelligent peripheral. Alternatively, the call flow logic is loaded into a control point  155  that is associated with the host intelligent peripheral  150  and that controls at least part of the call flow of the host intelligent peripheral  150 . 
         [0051]    According to the present invention, when the call flow of the host intelligent peripheral  150  reaches a point where the functionality of a service intelligent peripheral  170  is to be requested, the host intelligent peripheral  150  initiates a communication, e.g., a three way call, with the service intelligent peripheral  170  via the switch  105 . A three way call can be initiated using, for example, a flash hook mechanism that suspends the first call while a second call is placed by the host intelligent peripheral  150 . The first call and the second call are then bridged, via a second flash hook mechanism, into a three way call. When the functionality of the service intelligent peripheral  170  is no longer needed, the three way call is ended using, for example a third flash hook mechanism, so that only the calling party and the host intelligent peripheral  150  remain on the call. 
         [0052]    Alternatively, the call may be redirected using a two B channel transfer (TBCT) methodology. In the case of a two B channel transfer mechanism used to transfer the call to the service intelligent peripheral  170 , the two B channel transfer mechanism is again used to transfer the call back to the host intelligent peripheral  150  by the service intelligent peripheral  170  when the service intelligent peripheral  170  is finished processing the call. In the case where the call is redirected, the host intelligent peripheral  150  and the service intelligent peripheral  170  may communicate indirectly, e.g., through the control point  155 , to coordinate the transfer of the call and the call flow with the calling party. 
         [0053]    In an embodiment, the call flow with the calling party may be coordinated between the intelligent peripherals  150 ,  170  by forwarding the call flow sequence to a session database  180  as an entry after each intelligent peripheral  150 ,  170  is finished with the calling party. When the session database  180  is used, the intelligent peripherals  150 ,  170  retrieve the original or updated session information entry from the session database  180  before interacting with the calling party. When the two B channel transfer mechanism is used, the call can be transferred from one intelligent peripheral  150 ,  170  to the other, a session ID of the session information entry can be indirectly sent from one intelligent peripheral  150 ,  170  to the other via, e.g., the control point  155  and a SS7 network, and the updated call flow information can be forwarded and retrieved from the session database  180  as an entry corresponding to the session ID. 
         [0054]    In the case where a three way call is established, the host intelligent peripheral  150  and the service intelligent peripheral  170  are loaded with logic that enables direct communication between the two. The host intelligent peripheral  150  may be programmed to forward a particular series of DTMF tones to the service intelligent peripheral  170  so that the service intelligent peripheral  170  recognizes the functionality required for the calling party. In another embodiment, the host intelligent peripheral  150  may be programmed to forward a particular analog audio signal, e.g., a prerecorded or computer generated speech segment, to the service intelligent peripheral  170  so that the service intelligent peripheral  170  recognizes the functionality required for the calling party. The host intelligent peripheral  150  and the service intelligent peripheral  170  may interact before the three way call is completely established, e.g., before a second flash hook is performed to bridge the two calls at the switch  105 . 
         [0055]    The host intelligent peripheral  150  and the service intelligent peripheral  170  may interact after the second flash hook is performed also, although each intelligent peripheral  150 ,  170  will need to determine when it is being addressed by, e.g., a DTMF tone. In an embodiment, the host intelligent peripheral  150  will only monitor the call flow for specific messages, such as an end of call DTMF signal generated by the service intelligent peripheral  170 . The host intelligent peripheral  150  may also monitor the call flow for specific speech patterns from the calling party, such as “Help”, “Menu”, “Operator” or any other term that it is programmed to acknowledge. 
         [0056]    The host intelligent peripheral  150  may also monitor the call flow for a predetermined prefix of DTMF tones for signals from the service intelligent peripheral  170 , so that the host intelligent peripheral  150  recognizes when it is being addressed. Accordingly, after a three way call is established, the host intelligent peripheral  150  will monitor the call flow to recognize when it is being addressed by a speech message or DTMF signal. The host intelligent peripheral  170  will remain passive until a predetermined sequence of speech information or DTMF tones is recognized. 
         [0057]    After the second call is initiated by the first flash hook and before the three way call is established by the second flash hook, the intelligent peripherals  150 ,  170  may exchange information directly using, e.g., DTMF tones, prerecorded or computer generated speech. For example, DTMF tones may be used to exchange the session ID for the session information entry that has been forwarded to the session database  180 . The host intelligent peripheral  150  may be programmed to monitor DTMF tones for predetermined addressing prefixes or predetermined sequences, e.g., end of session tones, only during the three way portion of a call, e.g., after a second flash hook is performed by the host intelligent peripheral  150 . 
         [0058]    In an embodiment, the host intelligent peripheral  150  may communicate with the service intelligent peripheral  170  through, for example, a wide area network  160  and/or a local area network  190 . Alternatively, as has been described, the host intelligent peripheral  150  may communicate with the service intelligent peripheral  170  through the control point  155  and/or the switch  105 , in addition to the wide area network  160  and the local area network  190 , depending on the programming logic provided to the host intelligent peripheral  150  and the service intelligent peripheral  170 . 
         [0059]    The local area network  190  may be used for local communications in a subsystem  195  that includes the service intelligent peripheral  170 . The subsystem  195  includes a session database  180  that records information transacted between the calling party, the host intelligent peripheral  150  and the service intelligent peripheral  170 . The session database  180  may be connected to the host intelligent peripheral  150  through the local area network  190  and/or the wide area network  160 . The host intelligent peripheral  150  forwards the call session information entry to the session database  180  so that the service intelligent peripheral  170  can retrieve the entry information before interacting with the calling party. The service intelligent peripheral  170  updates the call session information entry and forwards the updated session information entry to the session database  180  before the host intelligent peripheral  150  resumes interaction with the calling party when the service intelligent peripheral  170  is finished interacting with the calling party. In this manner, once the determination is made to request the functionality of the service intelligent peripheral  170 , each of the host intelligent peripheral  150  and the service intelligent peripheral  170  are made aware of the previous call session information before interacting with the calling party. 
         [0060]    The subsystem  195  may also include an application server  185  that processes the data collected by the service intelligent peripheral  170  based on speech information or DTMF tone information from the calling party. Additionally, the subsystem  195  may include additional databases (not shown) that store instructions used to process the data from the calling party. The application server  185  may be used to retrieve the instructions from the additional database(s) to process information from the calling party and determine the call flow. 
         [0061]    As an example of the uses of the telecommunications network architecture shown in  FIG. 1 , a telecommunications service provider may allow subscribers to review service information by calling a service number corresponding to the host intelligent peripheral  150 . The information may be, for example, call forwarding information, call blocking information, call routing information, voicemail platform information or any other information associated with the telecommunications service provided to the calling party. Additionally, the telecommunications system may allow the calling party to request changes to the service using the host intelligent peripheral  150 . However, the telecommunications service provider may require additional functionality that is not available from the host intelligent peripheral  150  in order to process a particular request for a change in service, such as call forwarding or a change of password for a voicemail service. Accordingly, when the call flow of the call to the host intelligent peripheral  150  reaches the point where the calling party requests to update their call forwarding service, the host intelligent peripheral  150  initiates the three way call to the service intelligent peripheral  170 . 
         [0062]    As an example, the additional functionality may be functionality required to determine that a forwarding number is a valid number that can be used by the calling party. Accordingly, the subsystem  195  with the service intelligent peripheral  170  may be centrally provided and associated with one or more exhaustive databases that the telecommunications service provider does not wish to associate with the host intelligent peripheral  150 . Of course, the service intelligent peripheral  170  and the associated subsystem  195  may be duplicated according to, for example, different geographic regions. The subsystem  195  may be periodically updated, in order to more efficiently process requests that are forwarded to the service intelligent peripheral  170 . Additionally, the service intelligent peripheral  170  and the associated subsystem  195  may be duplicated in order to provide redundancy such that corruption of one subsystem will not necessarily result in corruption of the other. 
         [0063]    The databases associated with the service intelligent peripheral  170  may be any database that stores information for the service intelligent peripheral  170 . In an embodiment, a database associated with the service intelligent peripheral  170  may be a Public Safety database of the type used by emergency call centers, or a Line Information Database (LIDB). The database may store full textual representations of a subscriber name and address or, in the alternative, abbreviations so that data may be efficiently stored. Data corresponding to subscribers of multiple telecommunications service providers may be divided among many databases dispersed in an advanced intelligent network by any criteria, such as different telecommunications service providers, and geography. 
         [0064]    As another example of the uses of the telecommunications network architecture shown in  FIG. 1 , the host intelligent peripheral  150  may be used by a financial institution to allow a calling party to access an account. However, the financial institution may require the calling party to provide additional information in order to perform a transaction. Additionally, the financial institution may not wish to provide a transaction capability at the level of the host intelligent peripheral  150 . Accordingly, the service intelligent peripheral  170  may be used to match information of the calling party with information of the account-holder. Additionally, the service intelligent peripheral  170  may be centrally located in order to limit the number of intelligent peripherals used to arrange financial transactions over the telecommunications network. 
         [0065]    As yet another example, the service intelligent peripheral  170  may be used to change passwords and personal identification numbers. A telecommunications service provider may use a centrally located service intelligent peripheral  170  to minimize the number of intelligent peripherals used to request changes in passwords for a voicemail system. Additionally, a financial institution may use a centrally located service intelligent peripheral  170  to minimize the number of intelligent peripherals used to request changes in personal identification numbers for accounts. The service intelligent peripheral  170  may be associated with databases that store subscriber and customer information. Additionally, the service intelligent peripheral  170  may be more closely monitored than the host intelligent peripherals  150  that are used to reach the service intelligent peripheral  170 . In an embodiment, the service intelligent peripheral  170  may only accept calls from one or more host intelligent peripherals  150 , such that a calling party is blocked from calling the service intelligent peripheral  170  directly. 
         [0066]    As has been noted, the call flow of the host intelligent peripheral  150  and the service intelligent peripheral  170  may be self-directed or may be subject to the control of an external processor such as a service control point  155  of an advanced intelligent network. When call service instructions are stored at or otherwise directly associated with a service control point, the intelligent peripherals  150 ,  170  may retrieve the service information from the service control point  130  using the SR-3511 protocol. When not specified below, the methods and call flows described herein for the host intelligent peripheral  150  and/or the service intelligent peripheral  170  may be substantially under the control of the control point  115 ,  155  or may be substantially under the control of logic programmed into the respective intelligent peripheral  150 ,  170 . 
         [0067]    Additionally, the intelligent peripherals  150 ,  170  may retrieve data from an external database, such as a Name and Address Database (not shown) through a generic data interface (GDI) server (not shown) using, for example, a GetData command. For example, the subsystem  195  associated with the service intelligent peripheral  170  may retrieve data from a database using a generic data interface server. 
         [0068]    Accordingly, the telecommunications system of  FIG. 1  enables the integration of the disparate intelligent peripherals  150 ,  170  so that the functionality of the service intelligent peripheral  170  can be used to enhance the service provided for a call to the host intelligent peripheral  150 . The interaction between the host intelligent peripheral  150  and the service intelligent peripheral  170  may occur via the switch  105 , the control point  155 , wide area network  160  and a local area network  190 , or any other device or system that supports direct or indirect communication between the intelligent peripherals  150 ,  170 . 
         [0069]      FIG. 2  is an exemplary flow diagram showing a method for using the integrated disparate intelligent peripherals service architecture of the present invention. As shown, a calling party using an individual communications device  100  goes off hook and dials the service number to reach a service provided by the host intelligent peripheral  150  at S 201 . Upon receipt of the call, the switch  105  suspends the call and forwards a query to the control point  115  at S 202 . The control point  115  determines the call is for the service provided by the host intelligent peripheral  150  and sends a Forward_Call response to the switch  105  at S 204 . The switch  105  establishes a connection with the host intelligent peripheral  150  at S 205 . 
         [0070]    The host intelligent peripheral  150  processes the call according to a scripted call flow at S 210 . The call flow may vary depending on the information input by the calling party. At S 220 , an instruction to contact the service intelligent peripheral  170  is processed by the host intelligent peripheral  150  as part of the scripted call flow. The instruction is processed, e.g., as a result of the calling party requesting a function that is not supported by the host intelligent peripheral  150 . The host intelligent peripheral  150  is provisioned with logic to initiate a three way call to the service intelligent peripheral  170  and to interact with the service intelligent peripheral  170 . At S 226 , the host intelligent peripheral  150  calls the service intelligent peripheral  170 , e.g., after performing a first flash hook to obtain a new dial tone for calling the service intelligent peripheral  170 . The service intelligent peripheral  170  is also provisioned with logic to accept the call from the host intelligent peripheral  150  and to interact with the host intelligent peripheral  150 . At S 247 , the service intelligent peripheral  170  processes the call according to a scripted call flow. When the functionality of the service intelligent peripheral  170  is no longer needed, the service intelligent peripheral  170  is disconnected at S 252 . To disconnect from the call, the service intelligent peripheral  170  may generate, e.g., DTMF tones that are recognized by the host intelligent peripheral  150  to disconnect the service intelligent peripheral  170  from the call. 
         [0071]    The call flow at S 247  may include interaction between the host intelligent peripheral  150  and the service intelligent peripheral  170  before the three way call is established, i.e., before the call between the calling party and the host intelligent peripheral  150  is bridged with the call between the host intelligent peripheral  150  and the service intelligent peripheral  170  by a second flash hook mechanism. Once any necessary information is exchanged between the intelligent peripherals  150 ,  170 , the calls may be bridged by the second flash hook mechanism. In an embodiment, once the three way call is established, the host intelligent peripheral  150  passively monitors the call until the service intelligent peripheral  170  generates, e.g., predetermined DTMF tones, prerecorded speech or computer generated speech, to signal an end of the call flow between the calling party and the service intelligent peripheral  170 . When the predetermined DTMF tone(s) or speech is received, the host intelligent peripheral  150  performs a third flash hook to end the three way call. In another embodiment, the host intelligent peripheral  150  and the service intelligent peripheral  170  may communicate via the control point  155  or the wide area network  160  and/or the local area network  190 . Accordingly, the host intelligent peripheral  150  and the service intelligent peripheral  170  interact in order to provide an integrated service to the calling party. 
         [0072]      FIG. 3  shows an exemplary flow diagram of a method for using the host intelligent peripheral  150  of the integrated disparate intelligent peripherals. After starting, the call is processed at S 310  according to a scripted call flow. At S 310 , the calling party interacts with the host intelligent peripheral  150  according to a predetermined script that is provided for the host intelligent peripheral  150 . The predetermined script may be one or more software modules that include instructions. The script logic may branch depending on information provided by the calling party. 
         [0073]    The calling party may request a function that is not provided by the host intelligent peripheral  150 . Alternatively, the calling party may request information, e.g., billing information, that is not provided directly by the host intelligent peripheral  150 . Whenever, for any reason, the call flow reaches a point where the services of the service intelligent peripheral  170  are to be requested, an instruction of the script being processed instructs the host intelligent peripheral  150  to contact the service intelligent peripheral  170  at S 320 . 
         [0074]    When the host intelligent peripheral  150  is required to contact the service intelligent peripheral  170 , the host intelligent peripheral  150  creates a session information entry for the session database  180  at S 322 . The session information entry includes information relating to the interaction between the calling party and the host intelligent peripheral  150 . Additionally, the session information entry has a unique identifier that can be forwarded to the service intelligent peripheral  170  so that the service intelligent peripheral  170  can retrieve the session information entry. 
         [0075]    At S 324 , the host intelligent peripheral  150  performs a flash hook to obtain a dial tone to dial the service intelligent peripheral  170 . A flash hook is a process that can be used to establish a three way call. A first flash book is performed at S 324  to obtain the dial tone. The host intelligent peripheral  150  dials the service intelligent peripheral  170  at S 326 . At S 328 , the host intelligent peripheral  150  waits for DTMF tones. In particular, the service intelligent peripheral  170  is expected to generate DTMF tones to request a session ID, so the host intelligent peripheral  150  waits for the DTMF tones after dialing the intelligent peripheral at S 326 . When a determination is made at S 328  that DTMF tones are received, another determination is made at S 330  whether the DTMF tones are the predetermined tones to request the session ID. If DTMF tones are not received at S 328  (S 328 =No) or if the received DTMF tones are not a request for a session ID at S 330  (S 330 =No), a determination is made at S 332  whether a timeout has expired for waiting for the session ID request. If the timeout has expired (S 332 =Yes), a second flash hook is performed at S 344  to initiate the three way call temporarily, and a third flash hook is performed at S 352  to end the three way call by disconnecting the service intelligent peripheral  170 . The second flash hook is performed to “bridge” the first call, between the calling party and the host intelligent peripheral  150 , and the second call, between the host intelligent peripheral  150  and the service intelligent peripheral  170 . 
         [0076]    If the timeout period has not expired at S 332 , the system will again determine whether DTMF tones are received at S 328 , and whether received DTMF tones are a request for a session ID at S 330 . In this manner, the system waits for DTMF tones from the service intelligent peripheral  170  until a determination is made that either the timeout has expired at S 332 , or that received DTMF tones are a request for a session ID at S 330 . 
         [0077]    When a determination is made at S 330  that a request for a session ID has been received (S 330 =Yes), the host intelligent peripheral  150  sends DTMF tones corresponding to the session ID to the service intelligent peripheral  170  at S 334 . The host intelligent peripheral  150  then waits until DTMF tones are received again from the service intelligent peripheral  170  at S 336 . When the DTMF tones are received at S 336  (S 336 =Yes), the host intelligent peripheral determines whether the DTMF tones correspond to a code indicating that the session ID is valid (OK) at S 338 . If the session ID is not valid at S 338  (S 338 =No), a determination is made at S 340  whether the DTMF tones received at S 336  are an error code at S 340 . If the DTMF tones are not received at S 336  (S 336 =No), or if the DTMF codes are not an error code at S 340  (S 340 =No), a determination is made whether a timeout period has expired at S 342 . If the timeout period has not expired (S 342 =No), the host intelligent peripheral again waits for DTMF tones at S 336 . When a determination is made at S 340  that the DTMF codes are an error code (S 340 =Yes), or when the timeout has expired at S 342  (S 342 =Yes), the second flash hook is performed at S 344  and the third flash hook is performed at S 352  to disconnect the service intelligent peripheral  170  from the three way call. 
         [0078]    If the DTMF tones indicate that the session ID is valid at S 338  (S 338  Yes), a second flash hook is performed at S 346  to initiate the three way call so that the calling party can begin to interact with the service intelligent peripheral  170 . The host intelligent peripheral  150  remains passive at S 347  to monitor the DTMF tones that are transmitted by the calling party and/or the service intelligent peripheral  170 . A determination is made whether DTMF tones are received during the passive period at S 348 . If the DTMF tones are received (S 348  Yes), the host intelligent peripheral  150  determines at S 350  whether the DTMF tones correspond to a predetermined signal from the service intelligent peripheral  170  that the service intelligent peripheral  170  has finished with the calling party. If the host intelligent peripheral  150  determines that DTMF tones are not received at S 348  (S 348 =No), a determination is made at S 351  whether a timeout has expired. 
         [0079]    In an embodiment, the host intelligent peripheral  150  may also monitor the call flow at S 347  for other DTMF tones such as a request from the calling party to cancel the transaction that invoked the functionality of the service intelligent peripheral  170 . Additionally, the host intelligent peripheral  150  may monitor the call flow for any other signals from the calling party or the service intelligent peripheral  170 . The host intelligent peripheral  150  may monitor, for example, speech from the calling party, voice prints from the calling party, out of band messages from a calling party or any other audio signals that are transmitted during the three way call. Of course, any action that the host intelligent peripheral  150  takes as a result of recognizing a signal will be coordinated with the service intelligent peripheral  170 . 
         [0080]    For example, if the calling party requests to cancel a transaction and return to the previous menu, e.g., at the host intelligent peripheral  150 , the service intelligent peripheral  170  may automatically suspend its interaction with the calling party. The service intelligent peripheral  170  may also automatically forward the call flow information as an updated session information entry to the session database  180 . Once the host intelligent peripheral  150  obtains the updated session information entry from the session database  180 , the host intelligent peripheral  150  may resume interaction with the calling party. Of course, the host intelligent peripheral  150  and the service intelligent peripheral  170  may also coordinate the service being provided to the calling party by exchanging messages via the control point  155  and the SS7 network or via the wide area network  160 . 
         [0081]    If the DTMF tones are not an indication that the service intelligent peripheral  170  has finished with the calling party (S 350 =No), or if the timeout has not expired at S 351  (S 351 =No), the system again waits for DTMF tones at S 348 . In this manner, the host intelligent peripheral  150  waits until either a determination is made at S 350  that the service intelligent peripheral  170  has finished or a determination is made at S 351  that a timeout has expired. 
         [0082]    When the timeout has expired at S 351  (S 351 =Yes) or when the DTMF tones indicate the end of the service intelligent peripheral&#39;s  170  portion of the call flow (S 350 =Yes), the third flash hook is performed at S 352  to disconnect the service intelligent peripheral  170 . 
         [0083]    At S 354 , the host intelligent peripheral  150  obtains an updated session information entry corresponding to updated information of the call resulting from the calling party&#39;s interaction with the service intelligent peripheral  170 . The host intelligent peripheral  150  then resumes the scripted call flow at S 356  using any information collected from the service intelligent peripheral  170 . 
         [0084]    According to the embodiment of  FIG. 3 , when the three way call is established at S 346 , the host intelligent peripheral  150  monitors DTMF tones at S 347  until a determination is made that an end code is received at S 350 . The end code will be generated by the service intelligent peripheral  170 . Accordingly, the service intelligent peripheral  170  controls the call from the time of the flash hook at S 346  until the host intelligent peripheral  150  drops the service intelligent peripheral  170  from the call at S 352 . 
         [0085]    In an embodiment, information may be passed between the host intelligent peripheral  150  and the service intelligent peripheral  170  using, for example, the control point  155  or the wide are network  160 . Accordingly, the interaction and coordination between the intelligent peripherals  150 ,  170  need not occur via the switch  105 . For example, the call may be rerouted from the host intelligent peripheral  150  to the service intelligent peripheral  170 , in which case information between the intelligent peripherals may be exchanged using a SS7 signaling network and the control point  155 . Accordingly, the calling party can obtain the integrated services of the disparate intelligent peripherals  150 ,  170  as a result of the interaction and coordination between the host intelligent peripheral  150  and the service intelligent peripheral  170 . 
         [0086]      FIG. 4  shows an exemplary flow diagram for using the service intelligent peripheral  170  of the integrated disparate intelligent peripherals. After the process starts, an incoming call from the host intelligent peripheral  150  is answered at S 405 . At S 410 , the service intelligent peripheral  170  generates DTMF tones to request the session ID from the host intelligent peripheral  150 . At S 415 , DTMF tones that correspond to the session ID are received. At S 420 , the service intelligent peripheral  170  retrieves the session information entry from the session database  180 . 
         [0087]    At S 425 , a determination is made whether the session ID is valid. The determination may be made by, for example, determining whether the session ID corresponds to information of a session information entry recently collected by the host intelligent peripheral  150 . If the session ID is erroneous (S 425 =Yes), an error code is generated and forwarded to the host intelligent peripheral  150  at S 430 . The service intelligent peripheral  170  determines whether it has been disconnected from the call at S 435 . If the service intelligent peripheral  170  has not been disconnected (S 435 =No), a determination is made whether a timeout has occurred at S 440 . If the timeout has not expired at S 440  (S 440 =No), a determination is again made whether the host intelligent peripheral  150  has disconnected the service intelligent peripheral  170  from the call at S 435 . In this way, the service intelligent peripheral  170  waits until a determination is made that it has been disconnected at S 435  (S 435 =Yes) or the timeout has expired at S 440  (S 440 =Yes), and the process ends. 
         [0088]    If the session ID is not an error (S 425 =No), the service intelligent peripheral  170  forwards a session ID OK code at S 445 . The service intelligent peripheral  170  then initiates a call flow with the calling party at S 450  based on the information previously obtained by the host intelligent peripheral  150  and stored as the session information entry at the session database  180 . The call flow of the service intelligent peripheral  170  at S 450  corresponds to the passive period of the host intelligent peripheral  150  at S 347 . 
         [0089]    When the call flow of the service intelligent peripheral  170  with the calling party ends, the service intelligent peripheral  170  updates the session database  180  at S 455 . After updating the session database  180  at S 455 , the service intelligent peripheral  170  sends an end of session code to the host intelligent peripheral  150  at S 460 . After sending the end of session code to the host intelligent peripheral  150  at S 460 , the service intelligent peripheral  170  determines whether it has been disconnected at S 435  (S 435 =Yes) or whether the timeout expires at S 440  (S 440 =Yes). 
         [0090]    At S 450 , the call flow with the calling party is executed according to a routine that results in pre-recorded or digitally generated voice message being played to the calling party asking the calling party to provide information by, e.g., pressing buttons on the keypad of the calling party communication device  100  or speaking into the calling party communication device. If the calling party enters digits using the keypad, the service intelligent peripheral  170  collects the digits and translates the collected digits for processing according to the script. If the service intelligent peripheral  170  is controlled by the control point  155 , the collected information is provided to the control point  155  and the control point  155  instructs the service intelligent peripheral  170  to play another message to the calling party according to the script. However, if the service intelligent peripheral  170  is a service node/intelligent peripheral, then the call flow proceeds according to determinations made by the service intelligent peripheral  170  or, for example, the application server  185 . 
         [0091]    Accordingly, the functionality of the service intelligent peripheral  170  is provided to the calling party at the request of the host intelligent peripheral  150 . As is described above, the disparate intelligent peripherals  150 ,  170  are coordinated to provide an integrated service to the calling party. 
         [0092]    As another example of the uses of the integrated disparate intelligent peripherals, a travel agency with a host intelligent peripheral  150  may wish to temporarily connect a calling party to a service intelligent peripheral  170 . The service intelligent peripheral  170  may belong to a third party such as an airport authority, an airline or a governmental agency. The service intelligent peripheral  170  may provide updated flight status. Accordingly, by calling the travel agency, the calling party may be able to obtain information such as an updated flight status. Accordingly, the updated information in the databases associated with the service intelligent peripheral  170  may be easily accessed during a temporary three way call when a calling party calls a business. As a result, the calling party may only have to remember a single telephone number to obtain information from a variety of sources. 
         [0093]    As another example of the uses of the integrated disparate intelligent peripherals, a service intelligent peripheral  170  may be loaded with functionality to obtain and store, e.g., voice information from a calling party. Accordingly, a service intelligent peripheral  170  may be provided with a voice recording capability to store, for example, a customer&#39;s acquiescence to a purchase. After the service intelligent peripheral  170  begins interacting with the calling party, the service intelligent peripheral  170  may, for example, prompt the calling party to say “Yes” if the calling party agrees to purchase an item for a specified price. A portion of the agreement may be recorded and stored in case a disagreement occurs in the future as to whether a customer actually agreed to a purchase. 
         [0094]      FIG. 5  shows an exemplary call flow for a call using the integrated disparate intelligent peripherals. At S 502 , the call flow between the calling party and the host intelligent peripheral  150  occurs. At S 504 , the host intelligent peripheral  150  performs a first flash hook to initiate a call to the service intelligent peripheral  170 . At S 506 , the host intelligent peripheral  150  dials the service intelligent peripheral  170 . 
         [0095]    The service intelligent peripheral  170  answers the call and requests a session ID from the host intelligent peripheral  150  at S 508 . At S 510 , the host intelligent peripheral  150  forwards the session ID to the service intelligent peripheral  170 . The host intelligent peripheral  150  acknowledges the session ID at S 512  with either an OK signal or an Error signal. Additionally, the host intelligent peripheral  150  may forward a timeout expiration signal at S 512  if no session ID is received. 
         [0096]    If the session ID is OK, the host intelligent peripheral  150  performs a second flash hook at S 514  to bridge the call between the calling party and the host intelligent peripheral  150  with the call between the host intelligent peripheral  150  and the service intelligent peripheral  170 . At S 516 , the calling party interacts with the service intelligent peripheral  170 . While the calling party interacts with the service intelligent peripheral  170 , the host intelligent peripheral  150  passively monitors the call. At S 518 , the host intelligent peripheral  150  receives an end of session signal from the service intelligent peripheral  170 . The end of session signal indicates that the service intelligent peripheral  170  has finished interacting with the calling party. Accordingly, at S 520  the host intelligent peripheral  150  performs the third flash hook to disconnect the service intelligent peripheral  170  and end the three way call. At S 522 , the call flow between the calling party and the host intelligent peripheral  150  resumes. 
         [0097]      FIG. 6  shows another exemplary call flow for a call using the integrated disparate intelligent peripherals and a shared session database  180 . At S 602 , the host intelligent peripheral  150  creates a sessionData entry and forwards the entry to the session database  180  for storage. At S 604 , the session database  180  forwards a sessionID for the entry to the host intelligent peripheral  150 . 
         [0098]    The service intelligent peripheral  170  uses the sessionID at S 606  to obtain the sessionData entry from the session database  180  at S 608 . At S 610 , the service intelligent peripheral  170  updates the sessionData for the session by forwarding the sessionData to the session database  180 . 
         [0099]    At S 612 , the host intelligent peripheral  150  uses the session ID to obtain the sessionData from the session database  180  at S 614 . At S 616 , the host intelligent peripheral  150  removes the sessionID from the session database  180 . 
         [0100]    Accordingly, the host intelligent peripheral  150  and the service intelligent peripheral  170  may indirectly share information by loading a session information entry into a session database  180 . The loaded session information entry is retrieved by the next intelligent peripheral  150 ,  170  to interact with the calling party so that the information already collected from the calling party may be utilized. 
         [0101]    Of course, the host intelligent peripheral  150  and the service intelligent peripheral  170  may also share information via the switch  105 , the control point  155  or the wide area network  160  and local area network  190 . However, the indirect communication using the session database  180  may be more efficient than, e.g., using DTMF tones for large amounts of data. 
         [0102]    An exemplary use of the integrated disparate intelligent peripherals may include services for separate business entities. For example, a host intelligent peripheral  150  may belong to Zach&#39;s Chicago information service. A calling party calls Zach&#39;s and requests information on available hotel rooms on a particular date. Zach&#39;s host intelligent peripheral  150  may check a database and return a list of available hotels. The service may also offer to allow the calling party to reserve a room at a particular hotel. However, if the calling party agrees to reserve a room, the host intelligent peripheral  150  may require the calling party to provide information to a service intelligent peripheral  170  that belongs to the available hotel. Accordingly, the host intelligent peripheral  150  may perform a flash hook, dial the service intelligent peripheral  170  of the hotel, interact with the service intelligent peripheral  170 , and perform a second flash hook to initiate the three way call. The call flow may then proceed until the hotel&#39;s service intelligent peripheral  170  has collected the required information, in which case the host intelligent peripheral  150  will then resume interaction with the calling party. 
         [0103]    Of course, the integrated disparate intelligent peripherals may be used for many other purposes. As described above, the integrated disparate intelligent peripherals may be used to provide specific access to a service intelligent peripheral  170  of a third party vendor. Additionally, the integrated disparate intelligent peripherals may be used to provide access to a telecommunications provisioning system in order to request updates to a telecommunications service. Accordingly, the integrated disparate intelligent peripherals may be used in any environment where the functionality of a service intelligent peripheral  170  may be used to enhance the services of a host intelligent peripheral  150 . 
         [0104]    Although the invention has been described with reference to several exemplary embodiments, it is understood that the words that have been used are words of description and illustration, rather than words of limitation. Changes may be made within the purview of the appended claims, as presently stated and as amended, without departing from the scope and spirit of the invention in its aspects. Although the invention has been described with reference to particular means, materials and embodiments, the invention is not intended to be limited to the particulars disclosed; rather the invention extends to all functionally equivalent structures, methods, and uses such as are within the scope of the appended claims. 
         [0105]    For example, instead of a three way call, the integrated disparate intelligent peripherals may use two separate calls, in which case the interaction between the intelligent peripherals occurs only indirectly via, for example, the control point  155 . Additionally, timeouts may be used at any step of the present invention where an intelligent peripheral is waiting for a particular set of data. The present invention may also use error codes to signal, for example, that the host intelligent peripheral  150  should not resume interacting with the calling party, such as when the calling party provides a stolen credit card number to the service intelligent peripheral  170 . 
         [0106]    Additionally, the steps shown in the figures may be performed in a different order, or not be performed at all. Additional steps may also be performed by the integrated disparate intelligent peripherals. For example, S 310  and S 347  of  FIG. 3 , S 450  of  FIG. 4  and S 502 , S 514  and S 522  of  FIG. 5  may each include a variety of interactions between the calling party and one of the intelligent peripherals  150 ,  170 . Accordingly, any method of integrating disparate intelligent peripherals to provide an enhanced service may fall within the purview of the invention. 
         [0107]    In accordance with various embodiments of the present invention, the methods described herein are intended for operation as software programs running on a computer processor. Dedicated hardware implementations including, but not limited to, application specific integrated circuits, programmable logic arrays and other hardware devices can likewise be constructed to implement the methods described herein. Furthermore, alternative software implementations including, but not limited to, distributed processing or component/object distributed processing, parallel processing, or virtual machine processing can also be constructed to implement the methods described herein. 
         [0108]    It should also be noted that the software implementations of the present invention as described herein are optionally stored on a tangible storage medium, such as: a magnetic medium such as a disk or tape; a magneto-optical or optical medium such as a disk; or a solid state medium such as a memory card or other package that houses one or more read-only (non-volatile) memories, random access memories, or other re-writable (volatile) memories. A digital file attachment to email or other self-contained information archive or set of archives is considered a distribution medium equivalent to a tangible storage medium. Accordingly, the invention is considered to include a tangible storage medium or distribution medium, as listed herein and including art-recognized equivalents and successor media, in which the software implementations herein are stored. 
         [0109]    Although the present specification describes components and functions implemented in the embodiments with reference to particular standards and protocols, the invention is not limited to such standards and protocols. Each of the standards for channeled network transmissions (e.g. SS7, BR, PRI), packet switched network tansmission (e.g., TCP/IP, VOIP), and interface protocols (e.g., SR-3511) represent examples of the state of the art. Such standards are periodically superseded by faster or more efficient equivalents having essentially the same functions. Accordingly, replacement standards and protocols having the same functions are considered equivalents.
