Abstract: Network resources for a call between a calling party and a called party are allocated. The network resources for the call are reserved based on a reservation request. The network resources are reserved before any one network resource from the reserved network resources is committed. The reserved network resources for the call are committed when a called party indicates acceptance for the call.

Abstract: A client system includes a processor configured to obtain multicast information for a content item, the multicast information including information about a multicast session for a base stream and additional multicast sessions for available incremental streams. The processor is also configured to determine an available bandwidth, and to join a set of initial multicast sessions based on the available bandwidth, the set of initial multicast sessions including the multicast session for the base stream and at least one of the additional multicast sessions for the incremental streams. The processor is also configured to monitor a network condition, and to perform an action based on the network condition, the action selected from the group consisting of joining another of the additional multicast sessions, leaving one of the initial multicast sessions, and a combination thereof.

Abstract: A system and method for routing an incoming call to a subscriber-selected destination number in accordance with dynamic data concerning the subscriber provided by an address book, a calendar and a presence server. A routing system routes the incoming call in accordance with a subscriber-defined routing rule associated with the originating number of the incoming call, as determined from the address book. The routing rule may specify that the incoming call be routed to a destination number associated with the current date and time, as indicated by the calendar. The routing rule may specify, alternatively or in addition thereto, that the incoming call be routed to a destination number associated with a presence-enabled service on which the subscriber is currently active. The subscriber or caller may also be alternatively notified of the routing of the incoming call.

Abstract: Method and apparatus for caching caller-specific information to reduce query costs and to provide faster access when providing caller-specific information to called parties within communication networks.

Abstract: Network resources for a call between a calling party and a called party are allocated. The network resources for the call are reserved based on a reservation request. The network resources are reserved before any one network resource from the reserved network resources is committed. The reserved network resources for the call are committed when a called party indicates acceptance for the call.

Abstract: Segmented resource reservation is performed for at least one call. network resources associated with a first network are reserved according to that network's own reservation policy and based on an indication from a calling party. For the at least one call, network resources associated with a second network are reserved according to its own reservation policy and based on an indication from a called party. The second network is coupled to the first network.

Abstract: A call is forwarded by connecting the call between an originating location and a forwarding location without connecting the call through a terminating location. The originating location is associated with a calling party. The terminating location is associated with a dialed number. The terminating location and the forwarding location is associated with the called party. A bill for the call is apportioned between the calling party and the called party. The bill portion for the calling party is a function of the originating location and the terminating location. The bill portion for the called party is a function of the terminating location and the forwarding location.

Abstract: In a communication network that provides a path through a cable IP network between sending and receiving terminals residing on respective networks (e.g., an HFC, and/or PSTN network) controlled by different network managers or service providers, a controller hands off control of service access of the terminals between the service providers. Subscriber terminals may include broadband telephony interfaces, cable modems, or multimedia terminal adapters. To effect hand-off control, configurable modules of the terminals enable them to respond directly to a network manager (e.g., cable modem termination system or call management server) according to instructions supplied by the controller based either on subscriber authorization, database information, call type, dialing plan, and/or other parameters. Transfer of call control may also occur on a call-by-call basis.

Abstract: A system and method for routing an incoming call to a subscriber-selected destination number in accordance with dynamic data concerning the subscriber provided by an address book, a calendar and a presence server. A routing system routes the incoming call in accordance with a subscriber-defined routing rule associated with the originating number of the incoming call, as determined from the address book. The routing rule may specify that the incoming call be routed to a destination number associated with the current date and time, as indicated by the calendar. The routing rule may specify, alternatively or in addition thereto, that the incoming call be routed to a destination number associated with a presence-enabled service on which the subscriber is currently active. The subscriber or caller may also be alternatively notified of the routing of the incoming call.

Abstract: Network resources for a call between a calling party and a called party are allocated. The network resources for the call are reserved based on a reservation request. In particular, the network resources for the call are reserved based on a reservation request. Prior to the reservation request being made, one or more operational parameters for the call are established by a gate controller and sent to a network edge device or other routing entity associated with one of the parties. An identifier, illustratively a so-called gate identification, is sent to that party. Thereafter the routing entity receives the identifier from the associated party in, for example, the aforementioned resource reservation request. The routing entity is able to use the identifier to determine the one or more parameters established for the call and to thereupon cause the call to be established—including the reserving of resources—in a way that is consistent with the one or more parameters.

Abstract: Signaling messages are exchanged for a call between a calling party to a called party. A setup message for the call is exchanged through at least one gate controller. Network resources are reserved for the call based on the exchanged setup messages. An end-to-end message for the call is exchanged without the end-to-end message being routed through the at least one gate controller.

Abstract: Gates for a call between a calling party and a called party are coordinated. A timer associated with a first gate opened at an originating network edge device is initiated. A first gate open message is sent from the originating network edge device to the terminating network edge device. The first gate at the originating network edge device is released if the timer expires before at least one from the group of: (1) an acknowledgment based on the sent first gate open message is received from the terminating network edge device, and (2) a second gate open message is received at the originating network edge device from the terminating network edge device after the terminating network edge device has opened a second gate associated with the called party.
