  • Patent number: 9001664
    Abstract: Methods, systems, and computer readable media for providing sedation service in a telecommunications network are disclosed. According to one aspect, a method for providing sedation service in a telecommunications network is provided. The method includes steps that are performed at a session initiation protocol (SIP) sedation node. The method includes receiving a first message sent from a SIP user agent and intended for a SIP server. The method further includes determining whether the SIP server is unavailable.

  • Patent number: 8893248
    Abstract: Methods, systems, and computer readable media for media session policy compliance auditing and enforcement using a media relay and session initiation protocol (SIP) signaling are provided. One method includes at a SIP policy server, receiving SIP signaling from a user agent client to obtain a policy for media session and, in response, generating at least one media session correlation token. At least a portion of the SIP policy server is implemented in hardware. The media session correlation token and the media policy are communicated to the user agent client and to a media relay. Identification information for the media relay is also communicated to the user agent client. At least a portion of the media relay is implemented in hardware. At the media relay, the media session correlation token is received and used to correlate and store usage information for the media session and to monitor compliance with the media policy.

  • Patent number: 8499082
    Abstract: The subject matter described herein includes methods, systems, and computer readable media for providing services in a telecommunications network using an IOS/SIP adapter. According to one aspect of the subject matter described herein, a method for providing supplementary services to IMS devices and non-IMS devices using common IMS network components is provided. The method includes providing an interoperability specification/session initiation protocol (IOS/SIP) adapter configured to communicate with a base station subsystem and an IMS network. The method further includes, at the IOS/SIP adapter, receiving, from the base station subsystem a request for providing a supplementary service to a non-IMS device in communication with the base station subsystem. In response to the request, the method includes sending a message to an IMS node in the IMS network that provides the supplementary service to the non-IMS device and to IMS devices.

  • Patent number: 8321592
    Abstract: The subject matter described herein relates to methods, systems, and computer readable media for generating and using statelessly reversible representations of SIP information by SIP cluster entities. One method includes, at a first SIP cluster entity, receiving a first SIP message including SIP information. The method further includes generating a second SIP message including a statelessly reversible representation of the SIP information. The method further includes transmitting, to a SIP entity that is not a member of the cluster to which the first SIP entity belongs, the second SIP message with the statelessly reversible representation and information for reaching the cluster.

  • Patent number: 8090850
    Abstract: Methods, systems, and computer readable media for regulating pinhole preservation traffic generated or received by firewall or network address translator (NAT) session initiation protocol (SIP) user agent clients (UACs) are disclosed. One method includes, maintaining a list of contact information for a plurality of SIP UACs registering from behind at least one of a firewall and a NAT. The method further includes iterating through the list to generate SIP messages to the different UACs such that the SIP messages to the different UACs are spaced at substantially regular intervals with respect to each other, wherein the SIP messages to the different UACs trigger responses from the UACs such that the responses are spaced at substantially regular intervals with respect each other.

  • Patent number: 7366768
    Abstract: A method and apparatus for deploying and activating services in a communications network. In the context of a communications network that deploys service functionality by distributing managed software objects to service processing nodes, the present invention relates to selectively dispensing managed objects from a central repository and coordinating the instantaneous activation or deactivation of services throughout the network. Furthermore, where a managed object service creation environment is coupled to such a network, the method and apparatus of the present invention provides security, hack-up, and version control of managed objects and other network data stored in the repository.
