Abstract: A method of providing streaming audio to a non-streaming telephony audio interface can include receiving audio segments of a complete audio message and storing the audio segments in memory. A size of the audio segments can be determined. A callback can be registered for each of the audio segments, wherein each registered callback can be provided a timer value associated with the size of the audio segment for which the callback was registered. The complete audio message can be played when an active one of the callback timers expires.

Abstract: A method and system for generating multi-modal callback messages for a user of a wireless terminal connected to an access network. A multi-modal response is generated in response to a request for information with a multi-modal callback server. The multi-modal response is transmitted to the wireless terminal using the access network. A text-based response is included in the multi-modal response that includes a means for allowing a predetermined portion of the multi-modal response to be read aloud to the user of the wireless terminal or another message may be read aloud to the user.

Abstract: A system for the facilitation of direct response to conventional advertising and other media, initiated by a mobile subscriber to a wireless network, using a dial keypad on a mobile device, is disclosed. The system allows the subscriber to easily reply to a call to action and to be engaged in a dialogue with a service server or representative in a manner that dynamically matches the capabilities of the subscriber's device and the service requested. The system is implemented without any modifications to the wireless device or network.

Abstract: A method for notifying events to a node in a cluster includes (1) receiving a first event message and a second event message, (2) queuing the first and the second event messages, (3) sending the first event message to a first service callback, wherein the first service callback calls a first callback function to handle the first event message, (4) sending the first event message to a second service callback after (a) a the first service callback has handled the first event message and (b) a corresponding first service callback at a member node has handled the first event message, wherein the second service callback calls a second callback function to handle the first event message, and (5) sending the second event message to the first service callback after the first and the second callback functions have handled the first event message, wherein the first service callback calls the first callback function to handle the second event message. The method may further include sending a dummy message to the first callback function if the first callback function is waiting for a message from a sending node that is down. The method may also include sending a node down message to the first callback function if the first callback function is sending a message to a receiving node that is down.

Abstract: A method and a system for communicating with multiple user interface elements contained in multiple categories on a web page with a single client application program at the client computer. Messages are communicated both to and from users interface elements through callback function scripts that communicate through a single client application program that is connected over a point-to-point connection to an agent process on a server.

Abstract: A system and method for delivering asynchronous callbacks from a network server to clients that are unreachable by the network server. The system provides a callback server that receives callback registration requests from clients. The callback server generates a web service based on the description of the service that is being invoked by the client and an associated URL address based on its own address. The network server uses the dynamically generated service accessible at this URL address to deliver the asynchronous callbacks. The callbacks are either delivered to the clients by the callback server, if they are reachable inside the network domain, or made available on the callback server for the clients to poll. In addition, the callback server provides functionality that may be too expensive for the clients to provide locally.

Abstract: An application programming interface (API) for enabling a business layer of a tiered DICOM application to talk to different implementations of a data management layer The invention has particular application in a PACS view station In particular, the invention is directed to an API that forms the seam between a business layer that requests DICOM service by synchronous messaging and a data management layer that passes on those requests to the service provider by asynchronous messaging Thus, an application developer need not write code for the business layer that accounts for the DICOM callback mechanism, which confirms completion of a requested DICOM service Instead the data management implementation, which is hidden from the user, handles the callback mechanism so that responses to requests for DICOM service appear instantaneous to the user

Abstract: A method, apparatus and system arranged to provide a contract between an application server and a resource adapter that allows the resource adapter to do work (monitor network endpoints, call application components, etc) by submitting work instances to an application server for execution. In the described embodiment, the application server dispatches threads to execute submitted work instances thereby allowing the requesting resource adapter to avoid creating or managing threads directly. In this way, a mechanism for the resource adapter to do its work is provided as well as allowing the application server to efficiently pool threads and have more control over its runtime environment.

Abstract: oRis is a toolkit for interactive simulation : it is both an object-based concurrent programming language and an execution environment. Its features make oRis a generic plat- form for multiagent systems (MAS) implementation. It is a dynamically interpreted language, instance-grained which allows the user, during the execution, to observe the MAS, to interact with the agents or the environment et to modify them in line. With oRis, a MAS is compouned of agents (basically active objects) in an environment containing objets, eventually situated in space (2D or 3D) and time. oRis offers an homogenous solution for interactions, implemented as method invocation or callback or message passing (point-to-point or broadcast, synchronous or asynchronous processing). oRis offers different ways to manage the execution flows and the scheduler guarantees the equity of the time-sharing. oRis is stable and efficient. It has been used in many projects and is integrated in the AReVi virtual reality platform. MOTS-CLES : langage de programmation, programmation par objets concurrents, plate-forme, realite virtuelle, systemes multi-agents, simulation interactive.

Abstract: Designing a two-person game involves identifying the game model to compute the best moves, the user interface (the "view") to play the game, and the controller to coordinate the model and the view. A crucial task is to represent the algorithms used in their highest abstract forms. This can prove to be a difficult and subtle endeavor. It is made easier however by the use of good object-oriented (OO) design principles to help maintain a high level abstract viewpoint during the design process. The state pattern is used to represent the game board and is coupled with the visitor pattern to provide state-dependent, variant behaviors. The min-max algorithm and its variants are implemented as the strategy pattern, which allows flexible and extensible computational capability. Careful analysis is performed to properly abstract the interactions between the model and the view. The command design pattern is used to provide callback services between the model and the view. Leading students through this design process enables them to learn algorithms and architectures that easily scale to full-sized applications.

Abstract: A system and method of distributing contact volume in a contact center when the volume of incoming calls greatly exceeds the number of agents currently answering calls. In an embodiment of the invention, the caller calling in at such a peak time is notified of the relatively long wait time to speak to an agent. The caller is then prompted as to whether he or she wishes to hold or accept a later callback time to receive immediate service. By accepting a later callback, the caller may access the contact center at a later time by dialing a unique telephone number or by entering a unique code when dialing the main line. This scheduled return to queue with priority system and method seeks to essentially eliminate high call volume times by redistributing those calls to times when the agent volume exceeds the incoming call volume, thus ultimately decreasing call center staffing costs.

Abstract: Debugging a multiprocessor system utilizing at least two debuggers is disclosed. A user command is issued through a first debugger to a first processor in the multiprocessor system. The user command can be converted to a debugger RPC command by a first proxy module associated with the first debugger. The user command can be intercepted by a scheduler. A second processor in the multiprocessor system is then informed, for example by the scheduler, of the issuance of the user command. The user command is executed by both the first and second processors and both the first and second debuggers can then be informed by means of processor RPC commands of the execution of the user command. The processor RPC commands can be converted to callback commands by respective first and second proxy modules associated with the first and second processors when being sent to the first and second debuggers.

Abstract: The present invention encompasses various embodiments that provide convenient message callback for users in multi-service communication systems (e.g., 100 ). One set of embodiments enables users leaving messages to provide the callback number or address. This allows the calling party to indicate what communication service is preferable for callback. Another set of embodiments enables users retrieving messages to select the communication service they prefer for callback. The message server ( 114 ) provides this functionality by determining the callback number or address of the preferred type from the callback information provided by the original calling party. The present invention also provides for automatic callback once the called communication unit ( 102 ) receives the callback number or address.

Abstract: In cases when a called participant is not registered on a packet oriented network, a call-back request made by a calling subscriber is transmitted automatically to a substitutional device which is disposed in a network and assigned to the called subscriber. Preferably, the callback request is stored in a separate database. As soon as the called subscriber is registered in the network, the callback request is transmitted to the called subscriber.

Abstract: A system and method for enabling firewalled access to a client object residing behind a firewall, via an exported callback reference, by a server object outside the firewall. The system includes callback registry accessible by a proxy operating in conjunction with the firewall. The callback registry proxifies the callback object reference so that a callback will be directed to the proxy which in turn will redirect the callback to the callback object. Callback registry, additionally, stores callback definitions, callback registration and access control policies associated with registered callback objects. These access policies are applied to the callback for the server object to ensure that only authorized objects make the callback on authorized callback objects and their operations.

Abstract: In order to provide flexibility for a developer, a network API is provided which allows for a network event (for example, the receipt of data over the network) to be handled by one thread from among a predetermined number of dedicated threads. The number of dedicated threads is specified by the application at runtime and can be modified at runtime as well. Where the number of dedicated threads specified is greater than zero, dedicated threads are created which handle network events and call the specific callback functions of the application in response to the network events. Thus the number of such callback events from threads that can occur at one time is limited by the number of dedicated threads specified by the application. When the number of dedicated threads is specified as zero, no callback events can occur except when the application assigns a certain time period for them. Thus, when the number of dedicated threads created is zero, the application has control over the amount of processing time allotted to the network layer. Network events are handled when the application issues calls a “Do Work” method. While executing this method, network events are handled.

Abstract: PROBLEM TO BE SOLVED: To provide a reservation system and method that can allow a user, who wants to receive a telephone inquiry or consultation service but cannot get through because an operator's line is busy, to reliably receive the service by making a callback reservation with a time or condition specified over the Internet without needing further telephone calls. SOLUTION: The user enters customer information such as a customer ID, name, and telephone number, and a reservation time or a reservation condition and makes a callback reservation. A reservation acceptance unit 10 accepts the reservation from the user and notifies the user of reservation completion. When a user-specified time has come or a user-specified condition is satisfied, a reservation monitor unit 40 notifies an operator of the reservation request prompt the operator to call up the user. After the operator starts request processing, a reservation-request-processing update unit 30 updates a processing status of the reservation request. COPYRIGHT: (C)2003,JPO

Abstract: A system and method for providing multi-modal messaging for a wireless communication system. A wireless terminal is connected to a wireless access network, wherein the wireless terminal is capable of generating a voice request. A multi-modal message server is connected to the wireless access network for receiving the voice request generated by a user of the remote terminal. A voice-recognition application is operable to identify words contained in the voice request. A response-generation application uses the identified words to generate a response to the voice request. A unified messaging application is operable to interpret the response and generate a first and second response that is based on the contents of the response generated by the response-generation application. The first and second responses are then transmitted to the wireless terminal in different communication formats.

Abstract: A method of chaining together multiple dependent web-based procedure calls into a single request is disclosed. A request containing multiple MIME encoded service requests is transmitted to a first service. The request is parsed and the first service identified and performed. The results of the first service are appended to the remainder of the request which is forwarded to a second service listed in the request. The second service listed in the request may use the output of the first service as input and performs the second service. The process continues until the last service listed in the request is performed. Any output from the performance of the service requests is returned to the requesting device following execution of a MIME encoded callback request, the callback request being embedded in the original request following the last of the listed service requests.

Abstract: The invention relates to a method of redialing in telecommunication networks for a call back when not engaged, whereby a caller carries out a call attempt to reach a callee, whereby the callee does not respond at firs. According to the invention, the callee may be reached without the caller having to continually undertake a further call attempt, whereby a radialling is automatically carried out by the relevant exchange within a given time window at given time periods and a connection to the callee is established should the same respond.

Abstract: PURPOSE: A method for managing a short message in a mobile communication terminal is provided to decrease a time required for confirming the short message and improve the convenience of a user by classifying an unnecessary advertisement message and a message of a registered caller and managing the classified messages. CONSTITUTION: If a user selects a short message reception environment setting function, a reception group list is selected for separately managing messages according to a caller. If one group is selected among the reception group list, a sub-menu is outputted for setting the environment of the corresponding group. If a reception condition registration menu is selected in the outputted sub-menu, a reception or reception disapproval is selected under the condition that a specific callback number or character series is included. If an alarm sound selection menu is selected in the outputted sub-menu, an alarm sound capable of being designated in a terminal or a mute is selected. If an automatic callback setting menu is selected in the outputted sub-menu, a callback message about each group is registered for automatically returning a message when receiving the message.

Abstract: A method of processing callback requests included in web procedure calls through a firewall is discussed. A requesting device contacts a receiving device and requests the performance of a procedure. The procedure call includes a callback request that includes a destination address and port on the requesting device, as well as the address of a broker device. The receiving device parses the procedure call and identifies the requested service and the callback request and then terminates the connection with the requesting device. The receiving device executes the procedure and then requests a new connection to the broker device once the results of the requested service are obtained. The broker verifies the identity of the device and establishes a connection with the receiving device. The receiving device then transmits the results of the requested procedure to the broker which then forwards the results to the requesting device.

Abstract: A method of utilizing transport protocols to provide bidirectional web procedure calls is disclosed. A callback request included with a web procedure call provides a destination address and port on the requesting device to be utilized in a new connection for receiving the response from the receiving device. The utilization of a callback request included with a web procedure call enables a receiving device to terminate the original connection upon which it received the web procedure call while performing the requested procedure. In situations where the requested procedure takes an extended period of time or the receiving device is responding to a large number of requests, the ability to drop the original connection, perform the procedure, and respond to the requesting device via a new connection saves resources on the receiving device. Replies to the request are sent to the requesting device utilizing the destination address and port included as a parameter in the callback request. Access to the receiving device is increased as connections do not need to be held open.
