20100027532 | METHODS, SYSTEMS, AND COMPUTER READABLE MEDIA FOR PROVIDING SEDATION SERVICE IN A TELECOMMUNICATIONS NETWORK - 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. The method further includes responsive to a determination that the SIP server is unavailable to respond to the first message, sending, to the SIP client, a SIP sedation message for reducing the number or frequency of messages sent by the SIP user agent to the SIP server. | 02-04-2010 |
20100030914 | METHODS, SYSTEMS, AND COMPUTER READABLE MEDIA FOR THROTTLING TRAFFIC TO AN INTERNET PROTOCOL (IP) NETWORK SERVER USING ALIAS HOSTNAME IDENTIFIERS ASSIGNED TO THE IP NETWORK SERVER WITH A DOMAIN NAME SYSTEM (DNS) - Methods, systems, and computer readable media for throttling traffic to an IP network server using alias hostname identifiers assigned to the IP network server with a domain name system are disclosed. One method includes maintaining a plurality of weight values and corresponding alias hostname identifiers for the IP network server that are associated with the IP network server in a DNS system. The method further includes throttling network traffic sent to an IP network server by sending, from the IP network server, messages to nodes that send the traffic to the IP network server, where the messages selectively enable or disable traffic flow to the individual alias hostnames. | 02-04-2010 |
20100042731 | METHODS, SYSTEMS, AND COMPUTER READABLE MEDIA FOR SESSION INITIATION PROTOCOL (SIP) DIALOG IDENTIFICATION - Methods, systems, and computer readable media for session initiation protocol (SIP) dialog identification are disclosed. According to one method, a first SIP message associated with a SIP dialog is received. A dialog ID that is associated with the SIP dialog is computed using fields of the first SIP message. A second SIP message associated with the SIP dialog is generated. The computed dialog ID is included in the second message. | 02-18-2010 |
20100075669 | SYSTEMS, METHODS, AND COMPUTER READABLE MEDIA FOR PROVIDING DYNAMINC STEERING OF ROAMING IN A TELECOMMUNICATIONS NETWORK - Systems, methods, and computer readable media for providing dynamic steering of roaming in a telecommunications network are disclosed. According to one aspect, a method for providing dynamic steering or roaming in a telecommunications network includes a method for providing dynamic steering or roaming in a telecommunications network. The method includes, at a mobile telecommunications device, the device being associated with a subscriber of a first network, detecting a trigger condition for updating a roaming preference, where the trigger condition is not controlled by the operator of the first network, determining an identity of a second network, and performing at least one of: making a change to a preferred roaming network for the device by setting the second network as a preferred roaming network for the device, and connecting to the second network. | 03-25-2010 |
20100080371 | METHODS, SYSTEMS, AND COMPUTER READABLE MEDIA FOR PROVIDING ADVERTISING-SUPPORTED CALL SERVICE - Methods, systems, and computer readable media for advertising-supported call service are disclosed. According to one method, a SIP call setup message associated with a first call from a calling subscriber to a called subscriber is received. It is then determined whether the calling subscriber subscribes to a play advertisement pay less (PAPL) service. In response to determining that the calling subscriber subscribes to the PAPL service, an advertisement is presented to the calling subscriber via the subscriber's telephone, the call is connected to the called subscriber, and a reduced charge is effected for the call based on the PAPL service. | 04-01-2010 |
20100154047 | METHODS, SYSTEMS, AND COMPUTER READABLE MEDIA FOR MEDIA SESSION POLICY COMPLIANCE AUDITING AND ENFORCEMENT USING A MEDIA RELAY AND SESSION INITIATION PROTOCOL (SIP) SIGNALING - 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. | 06-17-2010 |
20100161809 | METHODS, SYSTEMS, AND COMPUTER READABLE MEDIA FOR REGULATING NETWORK ADDRESS TRANSLATOR (NAT) AND FIREWALL PINHOLE PRESERVATION TRAFFIC IN A SESSION INITIATION PROTOCOL (SIP) NETWORK - 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. | 06-24-2010 |
20100174821 | METHODS, SYSTEMS, AND COMPUTER READABLE MEDIA FOR GENERATING AND USING STATELESSLY REVERSIBLE REPRESENTATIONS OF SESSION INITIATION PROTOCOL (SIP) INFORMATION BY SIP CLUSTER ENTITIES - 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. | 07-08-2010 |
