IP-based services for circuit-switched networks

A mechanism for providing a connection from an IP-based network to a circuit-switched network, such as a GSM network is disclosed. A temporary routing number for the circuit-switched network, such as an E.164 number, is delivered to a user terminal, and a circuit-switched call leg is established from the user terminal to the IP-based network using the routing number. Thereby, IMS-services are provided for end users which are located in the radio access network not having sufficient QoS required for voice over IP. In the example of a conference call service, a request for a conference call may forwarded via a data channel or data path to an application server which provides that conference call service. The application server then selects a conference routing number and returns the routing number to the conference host terminal via the data channel. Using the received conference routing number, the conference host terminal can then set up a circuit-switched connection as a call leg of the conference call.

Self-healing hierarchical network management system, and methods and apparatus therefor

A hierarchical network management system (NMS) in which a plurality of NMS managers, each responsible for different portions or aggregations of a communications network, are logically arranged in a tree structure. The NMS managers are further organized into various sub-groups. The NMS managers within each sub-group monitor the status of one another in order to detect when one of them is no longer operational. If this happens, the remaining operational NMS managers of the sub-group collectively elect one of them to assume the responsibility of the non-operational NMS manager. The NMS is thus "self-healing" in the sense that one NMS manager can dynamically, without operator intervention, assume the responsibilities for another NMS manager.

Method and apparatus for providing full duplex and multipoint IP audio streaming

A conference server enables collaborative communications among a variety of client processes of varying configurations all operatively coupled over a computer network to each other and to the server. The server receives audio streams from participating client processes in a conference, selects which audio streams are active, and broadcasts one or more of the active audio streams to the client processes participating in the conference depending on the clients receiving capabilities and the conference parameters. The client processes receiving multiple active audio streams perform mixing locally at the client node. Without having to perform mixing at the server, resources are saved and the number of simultaneous participating client processes to the conference may be increased accordingly. The server is further capable of simultaneously accommodating multipoint clients and non-multipoint H.323 clients, as well as operating in multiway and “push to talkmodes.

Method for optimal path selection in traversal of packets through network address translators

Reduction of administrative overhead in maintaining network information, rapid convergence on an optimal routing path through the data network, and utilization of only required network resources are realized by a novel method for establishing a call path between network users. The method is based upon deployment of a network information server that stores network topology information and that is addressable by each end user. In this method, the network information server receives a request to establish a call path. The request identifies at least the calling party. In response to the request, the network information server determines a network traversal between the calling party and a root network wherein the network traversal includes call path information about the sub-networks between the calling party and the root network. The request for establishing a call path can also identify the called party. Based on the calling and called party identification, the network information server also determines a second network traversal between the called party and the root network. The second network traversal is sent to either the calling party or the called party or to both the calling and called parties. The server can determine an intersection of the traversals and send the intersection information to the parties. The intersection information is known as a merge point and represents an optimal call path between the parties.

System and method for multi-channel recording

Embodiments of the present invention are directed generally to recording communication of a call utilizing a multi-channel recording technique. According to one exemplary embodiment, inbound communication from each party to a call (e.g., from each communication device that is party to a call) to a recording system is assigned to a separate channel, and communication on each channel is independently recorded. Further, during the call, a control channel is generated that correlates the multiple communication channels. The independently recorded communication channels and control channel may be used to analyze a recorded call from any desired perspective. For instance, communication from a given party may be analyzed in isolation. Further, the control channel enables the recorded multiple communication channels to be correlated such that the communication received (e.g., heard) by any selected party may be accurately re-created for analysis thereof.

Providing services to packet flows in a network

A system and method for providing services to packet flows in a communication network. The services include enhanced charging, stateful firewalls, traffic performance optimization (TPO) and advanced services such as content differentiated charging, per-subscriber stateful firewalls, and VPNs, for example. A gateway can be used to route each packet flow through the services on a per-subscriber basis by inspecting accounting messages and checking subscriber profiles prior to setting up a new packet flow session. By directing the packet flow through the services requested latency can be reduced as well as the need to have equipment for each session regardless of whether the service is provided to the packet flow. The services can be provided in-line as well.

Apparatus and method for packet-based media communications

Packet-based central conference bridges, packet-based network interfaces and packet-based terminals are used for voice communications over a packet-based network. Modifications to these apparatuses can reduce the latency and the signal processing requirements while increasing the signal quality within a voice conference as well as point-to-point communications. For instance, by selecting the talkers prior to the decompression of the voice signals, decreases in the latency and increases in signal quality within the voice conference can result due to a possible removal of the decompression and subsequent compression operations in a conference bridge unnecessary in some circumstances. Further, the removal of the jitter buffers within the conference bridges and the moving of the mixing operation to the individual terminals and / or network interfaces are modifications that can cause lower latency and transcoding within the voice conference.

In response to the request, information may be obtained from the RAN regarding the capabilities of the user's Customer Premises Equipment (“CPE”). A profile may then be forwarded from the ASP to the RAN that specifies at least one policy regarding the transmission of data associated with the video on demand application flow across the RAN. The data associated with the video on demand application flow may then be forwarded across the RAN in accordance with the profile. The RAN may also be provided a default profile that specifies default policies that apply with respect to video on demand application flows that are transmitted across the RAN prior to obtaining information from the RAN regarding the capabilities of the CPE of any specific user. The user specific profiles may then be used to alter one or more policies specified in the default profile.
