Method and apparatus for providing integrated network and operations control for a converged communications network providing all service types on a common architecture.

Apparatus and method for controlling services and operations in converged communications networks

An access architecture for real-time communications is described. The architecture includes an inter-architecture network utilizing a single protocol, a plurality of border elements in communication with the inter-architecture network and with an external network, and one or more call control elements in communication with said inter-architecture network. The external network utilizes any of a variety of known networking technologies and protocols. The inter-architecture network utilizes a single protocol such as SIP. The present architecture provides a single common infrastructure for offering real-time communications services independent of call control protocols and networking technologies.

Access independent common architecture for real-time communications services for networking environments

A method and apparatus for providing routing of calls in a packet network, using one or more criteria extracted from signaling information to determine the routing for the calls are disclosed. The routing criteria extracted from signaling messages comprises at least one of: an access Uniform Resource Identifier, a destination phone number, a destination URI host, a calling party number, a calling party URI host, an incoming IP address, or a requested codec. An access URI and the egress URI are used to enhance routing decisions in a VoIP network. The egress URI can be used to specify egress route selections from the egress point of a VoIP network. The access URI can be used to influence the routing decisions within the VoIP network as well as the routing decisions with regard to egress routes from the egress point of the VoIP network.

Method and apparatus for providing access and egress uniform resource identifiers for routing

A method and apparatus for providing routing of calls in a packet network, e.g., a Voice over Internet Protocol (IP) network, using one or more criteria extracted from signaling information to determine the routing for the calls are disclosed. In one embodiment, the routing criteria extracted from signaling messages comprises at least one of: an access Uniform Resource Identifier, a destination phone number, a destination URI host, a calling party number, a calling party URI host, an incoming IP address, or a requested codec. An access URI and the egress URI are used to enhance routing decisions in a VoIP network. For instance, the egress URI can be used to specify egress route selections from the egress point of a VoIP network. The access URI can be used to influence the routing decisions within the VoIP network as well as the routing decisions with regard to egress routes from the egress point of the VoIP network.

A system and method for processing a plurality of requests for a plurality of multi-media services received at a Private Service Exchange (PSX) from a plurality of IP-communication devices. The system includes an IP Segmentation Directory (IP-SD) coupled to the PSX and to a plurality of IP Service Control Points (IP-SCPs), which are operative to process the plurality of requests for the plurality of multi-media services. The PSX is adapted to receive, process and redirect the plurality of requests for the plurality of multi-media services to the IP-SD. The IP-SD further receives, processes and selectively redirects the plurality of requests for the plurality of multi-media services to a predetermined IP-SCP of the plurality of IP-SCPs based on attributes of each of the plurality of requests for the plurality of multi-media services.

System and method for processing a plurality of requests for a plurality of multi-media services

Subscriber calls in a communications network () are handled in accordance with the subscriber's routing plan for either originating and/or terminating calls irrespective of the manner in which such calls originate and terminate. Upon receipt of a call, a query is launched to a database () to obtain a called party routing number for the call destination in accordance with the subscriber's routing plan. Once the called party's routing number is obtained in response to the query, the called party's routing number is mapped a to physical port in the network when the routing number corresponds to a circuit-switched call destination or to an IP address when the called party's routing number corresponds to a packet-based call destination. The call is routed to the call destination in accordance with the mapping.

Technique for providing intelligent features for calls in a communications network independent of network architecture

A method and apparatus for identifying and prioritizing applications and application servers in a Voice over IP network is disclosed. In a first embodiment, elements of signaling information are extracted from a call and are mapped to parameters associated with the call. These mapped parameters are then used by a service broker in a VoIP network to identify one or more application servers adapted to process the values of the respective parameter. The service broker may illustratively identify the application servers by a pointer to permit flexible reassignment of processing of a given parameter. The matched pointer/parameter combinations are then mapped to a precedence index. Then, according to this precedence index, the aforementioned pointers are mapped to specific addresses of application servers and the elements of signaling information are forwarded to those addresses for processing of applications.

Method and system for providing multi-media services incorporating a segmentation directory adapted to direct requests for multi-media services to one or more processors

A system and method for selectively routing telephone calls in an Advanced Intelligent Network, wherein an edge switch , comprising an AIN-equipped switching system, sends a query message to a service control point and receives a response message containing call discrimination information about a telephone call, whereby the edge switch determines whether to route the telephone call via a toll tandem office for further processing. The system further includes a segmentation directory which contains information determinative of which service control point has the service logic to process the call.
