A method for serving ip users by graphically-based interaction to agents of a call center

Abstract: Method and apparatus for connecting Internet or IP users to agents of a call center, which may be linked to an Internet web site. Visual information about quality of service, available agents, and history of previous connections, is transferred to the IP user via the IP network prior to voice call establishment, and a voice call is established according to inputs from the IP user which are responsive to the transferred information. An IP user who accesses a web site is identified and initiates a session with the serving call-center. Agent status information is stored at the call-center database. Information about the status and skills of each agent, which is stored at a database, is sent over the IP network and displayed on the screen of the IP user. A first selection menu is displayed on the screen and the IP user is requested to select between waiting for a preferred agent or sending voice or text messages. Available agents are displayed on the first menu, as well as their queuing time. If the IP user selects to wait, a second selection menu is displayed, thereby offering the IP user to continue to queue, or to queue for another agent, or to leave a voice message which may be delivered to the agent via voice mail. The IP user may send a text message which is displayed on the agent's display. After making all the desired selections and knowing the queuing time, a Voice-over-IP call between the IP user and the call-center may be established. The details of the connection between each IP user and his preferred agent during the current session are stored in a database.

Application Server Billing

Abstract: An Application Server entity in an IP Multimedia Subsystem (IMS) network comprises an interface for interfacing with an application and control logic which is arranged to inspect signalling information received from the application via the interface in the form of Extensible Markup Language (XML). The received signalling information is compared with stored rule data which specifies a relationship between an element in the signalling information and an action that should be taken and output data is generated based on the comparison. The Application Server can output operational measurements and/or charging information which more accurately reflect usage made of the Application Server resources. The need for a separate OSA/Parlay-X gateway can be avoided.

ITU-T QoS standards for IP-based networks

Abstract: To support IP/PSTN convergence, future IP networks will need to provide reliable differentiated QoS to a diverse set of user applications, including telephony. To achieve end-to-end QoS solutions, IP network providers will need to agree on a common set of IP packet transfer performance parameters and QoS objectives. This article describes two new ITU-T Recommendations, Y.1540 and Y.1541, that document such an agreement.

Interactive access, manipulation, sharing and exchange of multimedia data

Abstract: In a multimedia environment, end-users are provided with the ability to effectively access, manipulate and share one or more multimedia objects, or select portions thereof, independent of the terminal and/or network capabilities that are associated with the terminals employed by each end-user. This may be accomplished, for example, by identifying a set of multimedia data that is stored in a multimedia database that is accessible by each end-user. The set of multimedia data is then adapted in accordance with an information adaptation service and modified in accordance with a transcoder/scalability service. The functions provided by both of these services are based on a number of user preferences and based on a number of terminal and communication (e.g., network) connection capabilities associated with the terminals corresponding to each of the end-users that are to have access to the modified set of multimedia data.

Communication system supporting simultaneous voice and multimedia communications and method of operation therefore

Abstract: A communication system includes a voice subsystem and a multimedia subsystem. The voice subsystem couples to the PSTN and services a voice communication received by the communication system from a caller. The multimedia subsystem couples to the voice subsystem, supports multimedia communications and provides a multimedia interface to the caller upon receipt of the voice communication from the caller. When the call originates from a phone that supports multimedia communications, the multimedia subsystem directs the multimedia interface to the phone but, when the call originates from a phone that does not supports multimedia communications, the multimedia interface is directed to an associated multimedia enabled device. The voice subsystem provides call processing and routing functions as well as messaging functions and extended services. The multimedia subsystem includes an information posting subsystem and an information access subsystem that allow callers to post information and to access information. The multimedia subsystem may also include an application program interface subsystem that allows the caller to initiate execution of an application program on the multimedia subsystem. A universal inbox subsystem that receives, stores and delivers inbox items including voice messages, text messages and video messages via standard interchange protocols and languages. In operating the universal inbox, the multimedia subsystem supports delivery of all inbox items from the universal inbox subsystem to the caller via a standard transfer protocol. In such operation, the universal inbox subsystem converts inbox items to a standard format upon receipt. Methods of operation proceed according to the communication system described herein.
