  • Publication number: 20080037753
    Abstract: A call priority management system is implemented on or as part of one or more communication networks, for allowing authorized calling parties to control call disposition when the party being called is already on another call. In operation, when a first terminal initiates communication with a second terminal that is already in communication with a third terminal, the system determines if the newly initiated communication is a priority communication. By “priority” communication, it is meant a communication associated with a user and/or terminal having a designated or assigned privilege to interrupt ongoing communications at the second terminal. If so, the ongoing communication between the second and third terminals is interrupted, and a communication link is established between the first and second terminals. Prior to interruption, the calling party may be informed that the second/called terminal is already engaged in another call, for optionally interrupting the ongoing call.

  • Publication number: 20070256113
    Abstract: A user's favorite sources of content are monitored and when such a source generates a content stream of interest, it may be forwarded to the user. If the forwarding of the stream is interrupted, content transmitted during the period of the interruption will not be lost because it can be subsequently accessed by the user at a location, for example, last accessed by the user before the interruption occurred.

  • Publication number: 20060218268
    Abstract: In a VoIP network, based on a set of predetermined rules, a determination is made whether the running of an endpoint-hosted service on an intelligent VoIP endpoint and the running of a network-hosted service could cause a conflict to arise if both services were invoked during a call/session. If a determination is made that a conflict could arise between the endpoint-hosted service and the network-hosted service, then either the intelligent endpoint is instructed not to invoke the endpoint-hosted service during a call/session or to only invoke it with certain restrictions that would avoid the conflict, or alternatively, the network service is not invoked or is only invoked with certain restrictions that would avoid the conflict.

  • Publication number: 20060067323
    Abstract: When an intelligent VoIP endpoint terminal on a VoIP network becomes inoperative for any reason and can't respond to a service request that it had been programmed for, rather than leaving that service request unfulfilled, a VoIP network-hosted instance of that primarily endpoint terminal-provided service is invoked to handle that request and provide the service that would have otherwise been provided by the endpoint terminal. The network-hosted instance thus executes the requested service on behalf of the unavailable endpoint terminal.

  • Publication number: 20050190904
    Abstract: A network-based approach to calling user identification (Calling-user ID). A users identifies and authenticates himself directly to the telephone network. Each user is assigned a preferably unique identifier by a service provider. Before a user places a call, he identifies himself to the telephone network with use of the assigned identifier and authenticates his identity with use of a previously selected PIN (Personal Identification Number). When the user dials the call, the network propagates the saved user identification information corresponding to the provided identifier using the same conventional process used in prior art “Caller ID” systems for providing calling device information. Various telephony services including a service for providing the calling user identification to the called party (Calling-user ID), can then advantageously utilize this information.

  • Publication number: 20050147226
    Abstract: The concept of “roaming” is extended to wireline networks with a network hosted technique which emulates a wireline telecommunications network user's environment when the user is using a wireline telecommunications device located at a physical location other than his or her “home” location, or when using a wireline or wireless telecommunications device other than his or her own regardless of the location. Any telephone or other telecommunications device being used by the user advantageously appears to be logically connected directly to his or her home telecommunications network, irrespective of the location of the telephone or other telecommunications device being used and the telecommunications network to which that device is actually connected.

  • Publication number: 20050048981
    Abstract: A method and apparatus are provided such that when a wireless communication system detects that a connection to one of its subscribers has dropped, an application server within the network is dynamically called to intervene in the call and one or more options are presented to the remaining end-user of a mobile or landline terminal. The options presented to the end-user can be dependent upon whether the cause of the dropped call is one that is associated with likely having a short-term duration or is one that is associated with likely having a longer-term duration. If the cause is short term, the end-user can be given the option of being automatically reconnected to the dropped mobile terminal when it is determined to be available again.

  • Patent number: 6757796
    Abstract: Disclosed is a method and an apparatus for enhancing existing caching systems to better support the live broadcast of streaming multimedia over the Internet and other public network systems. The apparatus includes the use of helper servers in the network for supporting high quality live streaming multimedia (SM) broadcasts. The helper servers (HS), also referred to as helpers, are each positioned in the network to be close to some number of clients. Client requests for live SM broadcast objects are re-routed from the content server to the local HS to be serviced therefrom. Servicing requests from the local HS is advantageous in that the requests are not required to be serviced from the content server as separate unicast datastreams thereby reducing network congestion problems. In addition to servicing requests locally, each HS allocates and maintains PH buffers which operate as a form of dynamic cache to further reduce the playback delay at a client.

  • Publication number: 20040088349
    Abstract: An Internet Service Provider (ISP) intercepts HTTP requests from an end-user's browser, which are addressed to a Web server with which the ISP has an arrangement. If the request does not already include one, the request is modified to include a temporary user ID token that is identifiable with the end-user only by the ISP and not by the Web server. In response to receiving a request from the end-user that includes a token, the Web server generates a responsive message to the ISP that includes that same temporary user ID token, and which requests the ISP to perform a user-specific action. In response to that message, the ISP identifies the user from the token, performs the requested user-specific action and provides the Web server with information relating to the result of the requested action. The Web server then generates a response to the end-user's original request utilizing the provided information.
