  • Patent number: 8831200
    Abstract: Systems, methods, and computer readable media for communicating calling name information between signaling system 7 (SS7) and non-SS7 networks are disclosed. According to one aspect, the subject matter described herein includes a method for communicating calling name information between signaling system 7 (SS7) and non-SS7 networks. An entity for processing signaling messages receives an SS7 message that includes a calling party identifier, and uses the calling party identifier to obtain calling name information associated with the calling party. The SS7 message is modified to include the calling name information and sent to a gateway network element for communicating messages between SS7 networks and non-SS7 networks.

  • Patent number: 8532092
    Abstract: The subject matter described herein includes methods, systems, and computer readable media for providing NGN-based end user services to legacy subscribers in a communications network. According to one aspect, the subject matter described herein includes a method for providing NGN-based end user services to legacy subscribers in a communications network that includes, at a service creation system (SCS) node having at least one processor, using the at least one processor for receiving a SS7 call setup message associated with a call involving a legacy subscriber access device and holding the SS7 call setup message. The method also includes, while holding the SS7 call setup message, generating a SIP call setup message related to the SS7 call setup message, and initiating the providing of at least one NGN-based end user service for the call using the SIP call setup message.

  • Patent number: 8059667
    Abstract: Methods, systems, and computer program products for providing an enriched messaging service in a communications system is described. In one embodiment, the method includes receiving a signaling message associated with a call at one of a plurality of service dispatch and control (SDC) functions, wherein the call signaling message includes a subscriber identifier. A plurality of call services associated with the subscriber identifier that is to be applied to the call is determined. The method also includes communicating the signaling message from the SDC function to a service platform and receiving back at the SDC function for each of the plurality of call services and thereby sequentially applying the call services to the call.

  • Patent number: 8050253
    Abstract: Disclosed are methods, systems, and computer program products for decentralized triggerless processing of signaling messages in a multi-application processing environment. According to one method, a signaling message is received at a screening module. At least one application to perform message processing on the signaling message is determined from a screening policy. The signaling message is modified to include application routing information to allow the at least one application to complete signaling message routing. The signaling message is forwarded to, and routed by, the at least one application using the application routing information.

  • Publication number: 20110110274
    Abstract: Methods, systems, and computer readable media for inducing the activation of a service trigger at a switching office in a communications network are disclosed. According to one method, a call setup message associated with a call is received. It is then determined whether service trigger induction is required for the call. In response to determining that service trigger induction is required for the call, the call setup message is modified to include service trigger induction information and the modified call setup message is directed to a destination switching office. At the destination switching office, a service trigger is activated based on the service trigger induction information in the modified call setup message.
