Abstract: An approach provides fraud detection in support of data communication services. A list of single-event attributes (e.g., hot or cold attributes) is generated and includes a network address of an end user host originating a data call or a calling party identification (e.g., Automatic Number Identification (ANI) or an originating Calling Line Identification (CLI)) for network access, wherein entries of the list specify values of the hot attributes. An attribute value associated with the data call is compared with the entries. A fraud alert is generated if the attribute value matches one of the entries.

Abstract: A system and method are provided for providing access communications between customer locations and a core network service edge. Access flows are handled as carrier-tagged flows through a packet switched network comprising network elements that interpret and manipulate carrier tag values associated with traffic-bearing data frames.

Abstract: The present invention is directed to a method for placing a call between a client in one network and a client in another network. The IP network includes a SIP server and a network gateway configured to provide access to a public switched network. The method includes receiving a SIP call request message from the first client. The SIP call request message is authenticated to thereby identify an authentic originating client. Subsequently, a database is searched to find client billing tag corresponding to the authentic originating client. The call is completed if the client billing tag is obtained, and not completed if the client billing tag cannot be obtained. Thus, the present invention provides an efficient method for billing phone calls that are placed from SIP enabled devices to a telephone connected to the Public Switched Telephone Network (PSTN). The method of the present invention also substantially eliminates certain types of fraud.

Abstract: An external processor for a network access system having a programmable access device includes a service controller that provides at least one service for network traffic, a message processor that processes network messages for service processing by the service controller, and a programmable access device controller that programs the programmable access device in response to service controller processing. It is advantageous for the external processor to include primary and secondary service controllers for a particular service so that, if the primary service controller fails, the secondary service controller can provide the particular service for message received from the programmable access device.

Abstract: System and method for providing a layer 2 switch in the access network that switches based upon one or more carrier tags identifying customer traffic. Customer traffic conforming to any variety of different layer 1 or layer 2 protocols may be encapsulated and identified according to carrier tag values. The layer 2 switch may determine how to handle the traffic by interpreting and manipulating the carrier tag values. The layer 2 switch may be capable of switching TDM input traffic to either TDM or packet output traffic, and switching packetized input traffic to either TDM or packet output traffic. Handling classification values may also be processed by the layer 2 switch to affect prioritization of handling of encapsulated traffic.

Abstract: An approach providing the efficient use of speech synthesis in rendering text content as audio in a communications network. The communications network can include a telephony network and a data network in support of, for example, Voice over Internet Protocol (VoIP) services. A speech synthesis system receives a text string from either a telephony network, or a data network. The speech synthesis system determines whether a rendered audio file of the text string is stored in a database and to render the text string to output the rendered audio file, if the rendered audio is determined not to exist. The rendered audio file is stored in the database for re-use according to a hash value generated by the speech synthesis system based on the text string.

Abstract: An approach provides interdomain traversal to support packetized voice transmissions. A request is received and specifies a directory number for establishing a communication session from a first endpoint to a second endpoint. The first endpoint is behind a first network address translator of a first domain, and the second endpoint is within a second domain. A service provider network is accessed to determine a network address for communicating with the second endpoint based on the directory number, to determine existence of a second network address translator within the second domain, and to establish, if the network address can be determined, a media path between the first endpoint and the second endpoint based on the network address to support the communication session. An encrypted session is established with a proxy server according to a cryptographic protocol to support the media path. The proxy server resides within the second domain.

Abstract: A method may include determining that a label distribution protocol (LDP) session is not associated with an interface of a network device, wherein the interface of the network device is included in a targeted LDP session. Interior gateway protocol (IGP) metric information for both a physical interface associated with the network device and a forwarding adjacency label switched path (FA-LSP) associated with the targeted LDP (tLDP) session may be configured to each indicate a high cost. The configured metric information may be transmitted to other network devices in a network that includes the LSP and the targeted LDP session to inhibit selection of the targeted LDP session by the other network devices when routing data through the network.

Abstract: A method of monitoring the stability of a network includes polling an inter-network gateway to collect data related to the inter-network gateway.

Abstract: System and method for providing a termination point for service emulation instances in an access network is provided. In an embodiment, the service emulation instances are implemented utilizing, for example, pseudowires. Communications to and from the access network are aggregated and transmitted via one or more pseudowires to a service emulation instance terminator. The service emulation instance terminator converts the traffic to its native form and, if necessary, converts the traffic to a different type of format or service. The service emulation instance terminator then frames the traffic for the appropriate type of service and transmits the traffic to the service edge. Traffic received from the service is removed prepended with a pseudowire label and aggregated with other traffic. The aggregated traffic is transmitted to the customer via the access network. If necessary, an interworking function may convert the traffic from one type of service to another type of service.
