A server-client system or architecture that allows datacast applications to reliably transport data objects from a network server over a unidirectional packet network ('datacast network') to one or more clients, each of which may be listening to the packet stream at different times. The invention allows the clients to listen intermittently to the datacast, yet still receive all of the data objects published by the server in a timely manner, and in a way that is more optimal in terms of client resource use. This ensures that listening clients can receive a complete set of the data objects broadcast while being able to conserve client processing and power resources by not requiring continuous listening by the client to the datacast.

Datacasting system with intermittent listener capability

Applications in a broadcast environment distribute events in real-time to a large number of receivers within specified geographic locations while efficiently sharing bandwidth resources with other applications using the same broadcast network. Applications need not be aware of the other applications sharing the resources, nor of the methods, protocols, and other mechanisms used to actually broadcast the data over the broadcast medium. Server-side applications that serve data, send notifications, or distribute events to specific locations within the network use a broadcast location manager. Client applications that receive such data, notifications, or events use a client location filter to obtain events that are relevant based on the location of the device. The broadcast location manager and client location filter work together to reliably and efficiently transmit data, notifications, and events to specific locations over the broadcast network for all applications involved.

Location specific event broadcasting

Data may be transmitted in a broadcast mode to multiple devices operating in a network. Efficient utilization of bandwidth while providing a desired level of quality of service is enabled for the applications executing on the devices that utilize the broadcasted data. A set of bandwidth constraints may be utilized in combination with a set of heuristics and rules for the allocation and re-allocation of bandwidth among multiple applications in a manner that minimizes the impact on the quality of service metrics of importance to the affected applications when contention exists for the network resources. Quality of service provided to each application may be degraded smoothly, with certain priorities and guarantees being maintained. Event segmentation and reassembly functions for applications may be provided, as well as reliability mechanisms to increase the ability to provide data to client devices that have not been actively receiving for significant periods of time.

Reliable event broadcaster with multiplexing and bandwidth control functions

Datacasting systems may include one or more compound carousels each managing one or more elementary carousels, and managed by a bandwidth manager. Subsets of compounds carousels may be identified, for example, according to priority levels. Bandwidth allocations may be determined for the compound carousels. For example, the bandwidth manager may utilize multiple bandwidth allocation cycles to determine the bandwidth allocations. The multiple bandwidth allocation cycles may form a sequence. Each bandwidth allocation cycle may at least partially allocate an available datacasting bandwidth resource to at least one of the identified subsets of the compound carousels. The allocations may be based at least in part on desired bandwidths determined by the compound carousels and/or one or more bandwidth guidelines of datacast sessions associated with the compound carousels.

Datacasting system with hierarchical delivery quality of service management capability

A system, apparatus, and method for transmitting data in a broadcast mode to multiple devices operating in a network. The invention enables the efficient utilization of bandwidth while providing a desired level of quality of service for the applications executing on the devices that utilize the broadcasted data. The invention utilizes a set of bandwidth constraints in combination with a set of heuristics and rules for the allocation and re-allocation of bandwidth among multiple applications in a manner that minimizes the impact on the quality of service metrics of importance to the affected applications when contention exists for the network resources. The present invention implements processes to cause the quality of service provided to each application to degrade smoothly, with certain priorities and guarantees being maintained. The present invention also provides event segmentation and reassembly functions for applications, and includes reliability mechanisms to increase the ability to provide data to client devices that have not been actively receiving for significant periods of time.

A datacast system, and associated apparatus and method for automatically managing a data object or objects within a hierarchical carousel structure by enabling, among other functions, the dynamic allocation of bandwidth to each carousel within the structure. The dynamic bandwidth allocation enables a server platform to redistribute the bandwidth allocated to a carousel or set of data objects to adjust to desired changes in object transmission policies or priorities of a datacast application.

Datacasting system with automatic delivery of service mangement capability

In one embodiment, a communication device includes an outgoing call alerting agentthat (i) detects that a communication device has entered an off-hook state and that a first line appearance has been selected by a user for an outgoing call, (ii) forwards a first call setup message to a third party call controller, the call setup message including a request to reserve the first line appearance for the outgoing call, and (iii) thereafter collects a set of digits dialed by the user for the outgoing call and provides the collected set of digits to the third party call controller.

Line appearance reservation for SIP endpoints

The present invention is directed to an architecturefor setting up a communication between first and second communication devicesand, the first communication devicecorresponding to a first directing serverand first communication managerseparate from the first directing server, comprising a contact servicing agentoperable to (a) receive a call set up message at least one of addressed to and originated by the first communication device; (b) determine that the first communication devicehas a corresponding first communication manager; (c) forward the call set up message to the first communication managerand request the first communication managerto perform at least one of call originating and terminating processing; and (d) rout the call set up message to a destination referenced in the call set up message.
